vectorbt - blazingly fast backtesting and interactive data analysis for quants
I want to share with you a tool that I was continuously developing during the last couple of months. https://github.com/polakowo/vectorbt As a data scientist, when I first started flirting with quant trading, I quickly realized that there is a shortage of Python packages that can actually enable me to iterate over a long list of possible strategies and hyper-parameters quickly. Most open-source backtesting libraries are very evolved in terms of functionality, but simply lack speed. Questions like "Which strategy is better: X or Y?" require fast computation and transformation of data. This not only prolongs your lifecycle of designing strategies, but is dangerous after all: limited number of tests is similar to a tunnel vision - it prevents you from seeing the bigger picture and makes you dive into the market blindly. After trying tweaking pandas, multiprocessing, and even evaluating my strategies on a cluster with Spark, I finally found myself using Numba - a Python library that can compile slow Python code to be run at native machine code speed. And since there were no packages in the Python ecosystem that could even closely match the speed of my own backtests, I made vectorbt. vectorbt combines pandas, NumPy and Numba sauce to obtain orders-of-magnitude speedup over other libraries. It builds upon the idea that each instance of a trading strategy can be represented in a vectorized form, so multiple strategy instances can be packed into a single multi-dimensional array. In this form, they can processed in a highly efficient manner and compared easily. It also integrates Plotly and ipywidgets to display complex charts and dashboards akin to Tableau right in the Jupyter notebook. You can find basic examples and explanations in the documentation. Below is an example of doing in total 67,032 tests on three different timeframes of Bitcoin price history to explore how performance of a MACD strategy depends upon various combinations of fast, slow and signal windows:
import vectorbt as vbt import numpy as np import yfinance as yf from itertools import combinations, product # Fetch daily price of Bitcoin price = yf.Ticker("BTC-USD").history(period="max")['Close'] price = price.vbt.split_into_ranges(n=3) # Define hyper-parameter space # 49 fast x 49 slow x 19 signal fast_windows, slow_windows, signal_windows = vbt.indicators.create_param_combs( (product, (combinations, np.arange(2, 51, 1), 2), np.arange(2, 21, 1))) # Run MACD indicator macd_ind = vbt.MACD.from_params( price, fast_window=fast_windows, slow_window=slow_windows, signal_window=signal_windows, hide_params=['macd_ewm', 'signal_ewm'] ) # Long when MACD is above zero AND signal entries = macd_ind.macd_above(0) & macd_ind.macd_above(macd_ind.signal) # Short when MACD is below zero OR signal exits = macd_ind.macd_below(0) | macd_ind.macd_below(macd_ind.signal) # Build portfolio portfolio = vbt.Portfolio.from_signals( price.vbt.tile(len(fast_windows)), entries, exits, fees=0.001, freq='1D') # Draw all window combinations as a 3D volume fig = portfolio.total_return.vbt.volume( x_level='macd_fast_window', y_level='macd_slow_window', z_level='macd_signal_window', slider_level='range_start', template='plotly_dark', trace_kwargs=dict( colorscale='Viridis', colorbar=dict( title='Total return', tickformat='%' ) ) ) fig.show()
Analyze and engineer features for any time series data
Supercharge pandas and your favorite tools to run much faster
Test thousands of strategies, configurations, assets, and time ranges in one go
Test machine learning models
Build interactive charts/dashboards without leaving Jupyter
The current implementation has limitations though:
It's still experimental and fast evolving, thus API can change quickly.
Fast processing means more memory requirements. Above example created multiple DataFrames each taking 46MB of RAM (price, signals, cash, shares, equity, returns, etc). The issue can be mitigated by deleting at least some artifacts as soon as they are created and by disabling caching.
Usage requires intermediate knowledge of pandas and NumPy to understand what's going on. Numba can be learned faster because of it mimicking NumPy. I tried to make lots of small examples in the documentation to get the idea how everything is glued together.
The approach of merging vectorized and iterative code differs significantly from classic OOP approach of designing strategies, and will require you to rethink how strategies are formulated and implemented (which is kinda fun).
Finally, if you're looking for a pure backtesting solution - it's not. It's more of a data mining tool to get to know your market and approach better.
If it sounds cool enough, try it out! I would love if you'd give me some feedback and contribute to it at some point, as the codebase has grown very fast. Cheers.
JDE Project Rating (A)-Convergent Decentralized Financial Agreement
2020 is the year of the outbreak of the DeFi market. As products of the DeFi 1.0 era, Maker, AAVE, and Compound have become the infrastructure of DeFI. Innovative projects of DeFi 2.0 represented by Uniswap and YFI have gradually attracted the attention of the market. Currently, DeFI 3.0 has emerged, technology innovation + business model innovation has become the theme of 3.0, and innovative projects represented by JDE have gradually occupied the market. This article focuses on the analysis of the JDE project and comprehensively evaluates the JDE project. Project Positioning——A- JDE is called Just for Decentralization. The project is positioned as a decentralized DeFi aggregator protocol. In the current DeFi market, each product is an independent agreement, providing users with independent products. For the user side, every DeFi project operation has a certain threshold. If a user selects multiple DeFi products at the same time, the complexity of the operation will be much higher. JDE's centralized decentralized protocol can better satisfy users' multi-faceted and full-ecological services. You can enjoy DeFi financial services with only one key operation. Aggregation services are the most urgent needs of users in the current market. For example, similar to loan product AAVE, wealth management product Maker, insurance product NXM, etc., users must perform separate operations on each platform if they want to achieve their needs. The high threshold of DeFI will also prevent some users from entering this decentralized world. JDE provides a complete protocol suite to allow users to perform fool-like one-key operations. On JDE's platform, it includes loan agreement, payment agreement, insurance agreement, decentralized transaction agreement and Game ecological agreement. Users can operate a variety of decentralized financial products on the protocol cluster. This positioning is very in line with the needs of current DeFi market users, and can serve millions of DeFi industry users to provide accurate services. Project Technology-A The DeFi project has high technical requirements. Each agreement is an independent individual, so a complete financial agreement aggregator has higher technical requirements. The technology of JDE has been developed for many years. JDE has created an on-chain and off-chain two-layer solution, which allows each protocol to be completed quickly in a short time, and the protocol cluster can also complete the interaction more quickly. Compared with other platforms, JDE's contract interaction time can be reduced by 60%. JDE's Layer 2 solution transfers transactions and transfers on the chain to off-chain, completes a Transaction off-chain, and then performs backup packaging on the chain. At the same time, JDE has added Aztec, a completely anonymous privacy protocol, which can provide more secure and anonymous services than Bitcoin. The following is the technical architecture diagram of JDE JDE implements Full Stake DeFI on the technical side. As the basic ecological platform, JDE integrates mainstream products in the DeFi 1.0 and 2.0 eras, such as Maker, AAVE, BZX, Uniswap, Curve, YFI and other projects. It also provides projects based on ETH Full Stake DeFI, an independent solution, builds mainstream DeFi application components. Realize one end to meet all DeFi requirements. JDE's protocol cluster will choose the most suitable product for users from mainstream products and products built by itself, make intelligent judgments between profitability and security, and then launch products that are most suitable for users. According to the needs of users, it will intelligently choose the products that best meet the users. Each parameter in the JDE aggregation protocol will go through dozens of demonstrations to ensure that each parameter is in the safest state. JDE's technical teams are all from well-known companies around the world, and have a very deep technical foundation in the blockchain field. Compared with the technology of many DeFi projects on the market, the technical requirements of JDE are more complex. The technical aspect scored A. Product solution——A+ JDE provides the safest guarantee for products at the bottom of the technology. Provides the most comprehensive and complete ecological services on the product side. JDE Ecology provides DeFI financial product solutions including asset pools, loan products, payment wallets, trading products DEX, insurance protection products, game products, etc. Throughout the current DeFi financial products on the market, they can only provide a single product and service. But on the JDE platform, users can enjoy all aspects and the entire ecosystem of financial services. From the most basic asset pool for mining, lending to payment, to decentralized DEX platform transactions, insurance services, and game product services. Covers the various needs of mainstream users. The product solution combines the various needs of the market. Focus on the asset pool JDE DAO Pool-V1. This is a more popular mining product today. In this product of JDE, users provide liquidity by depositing mainstream assets ETH, wBTC, USDT, etc., and can perform lending and DEX liquid pool transactions on the platform. Here the user's mortgage loan is a full mortgage, so the platform transplantation can be guaranteed to be in a safe state. When the user's mortgaged assets cannot cover the user's loaned assets, the platform will automatically liquidate. At this time, the platform will charge a 5% liquidation fee. JDE Ecological DEX trading products are also the main source of revenue for the platform. The platform will charge a transaction fee of 0.2%, which is the lowest in the entire network. The handling fees of other platforms are above 0.3%. Users can inject liquidity into the DEX platform to become a market maker. The platform is very friendly to the project party, can list currency without review, and provide automated market services. The DEX trading platform can help the platform earn hundreds of thousands of dollars in handling fees (compared to the trading fee of the Uniswap platform). JDE Eco provides a complete and multi-faceted product solution, and users can enjoy one-stop service. The product angle is rated A. Economic Model-A JDE is the first ecosystem in the entire network to successfully implement DAO governance. If you want to make product-related proposals in the JDE ecosystem, you must get the approval of the autonomous committee, which is composed of all currency holders. Each coin-holding user realizes a complete process of autonomy by voting on proposals. JDE's token, JDE, not only has appreciation rights, but also has very large autonomy rights. Let's take a look at the JDE sub-token economy. The total amount of JDE is 10 million and will never be issued. Among them, 70% is used for community liquidity mining; 5% is owned by the technical team and locked for one year; 1% is for community private placement (20% is issued online, and 10% is released every week); 5% is an insurance pool; 10 % Is the DAO Autonomous Community Ecological Fund. In the JDE economic model, almost 80% of the tokens are allocated to liquid mining, which is a very high proportion. Early rewards can be given to users who participate in the JDE community early. Users can get liquidity rewards for asset deposits, loans, DEX transactions, etc. in the JDE ecosystem. Only the technical section is allocated to the team, and the position is locked for long enough. 10% is the DAO autonomous community ecological fund, which participates in the DAO autonomous ecology. 5% is the insurance pool, which provides liquidity of funds. 1% is given to community welfare and allocated to users who participated in the early stage. The profit of the products and services of JDE ecology will be repurchased in the JDE secondary market, which is always in a state of deflation. This economic model provides a long-term development guarantee for the JDE ecology. The economic model community surpasses most projects in the industry. The economic model is scored as A. Comprehensive analysis, JDE ecology has a layout in the Defi field for many years, and at the same time has a very complete design in project positioning, product solutions, technological development, economic models and other sectors. The products in JDE's product solution will be gradually launched to provide users with the most complete ecological services. The prospects of the JDE project are good. It is currently in the early stages of project development. I look forward to the launch of JDE products to provide users with DeFi ecosystem services!
[OWL WATCH] Waiting for "IOTA TIME" 20; Hans's re-defined directions for DLT
Disclaimer: This is my editing, so there could be some misunderstandings... -------------------------------------------- wellwho오늘 오후 4:50 u/BenRoyce****how far is society2 from having something clickable powered by IOTA? Ben Royce오늘 오후 4:51 demo of basic tech late sep/ early oct. MVP early 2021 --------------------------------------------------- HusQy Colored coins are the most misunderstood upcoming feature of the IOTA protocol. A lot of people see them just as a competitor to ERC-20 tokens on ETH and therefore a way of tokenizing things on IOTA, but they are much more important because they enable "consensus on data". Bob All this stuff already works on neblio but decentralized and scaling to 3500 tps HusQy Neblio has 8 mb blocks with 30 seconds blocktime.This is a throughput of 8 mb / 30 seconds = 267 kb per second.Transactions are 401+ bytes which means that throughput is 267 kb / 401 bytes = 665 TPS. IOTA is faster, feeless and will get even faster with the next update ... ----------------------------------------------------------------------------- HusQy Which DLT would be more secure? One that is collaboratively validated by the economic actors of the world (coporations, companies, foundations, states, people) or one that is validated by an anonymous group of wealthy crypto holders? HusQy The problem with current DLTs is that we use protection mechanisms like Proof of Work and Proof of Stake that are inherently hard to shard. The more shards you have, the more you have to distribute your hashing power and your stake and the less secure the system becomes. HusQy Real world identities (i.e. all the big economic actors) however could shard into as many shards as necessary without making the system less secure. Todays DLTs waste trust in the same way as PoW wastes energy. HusQy Is a secure money worth anything if you can't trust the economic actors that you would buy stuff from? If you buy a car from Volkswagen and they just beat you up and throw you out of the shop after you payed then a secure money won't be useful either :P HusQy **I believe that if you want to make DLT work and be successful then we need to ultimately incorporate things like trust in entities into the technology.**Examples likes wirecard show that trusting a single company is problematic buttrusting the economy as a whole should be at ... **... least as secure as todays DLTs.**And as soon as you add sharding it will be orders of magnitude more secure.DLT has failed to deliver because people have tried to build a system in vacuum that completely ignores things that already exist and that you can leverage on. ---------------------------------------------------------------------------------- HusQy Blockchain is a bit like people sitting in a room, trying to communicate through BINGO sheets. While they talk, they write down some of the things that have been said and as soon as one screams BINGO! he hands around his sheet to inform everybody about what has been said. HusQy If you think that this is the most efficient form of communication for people sitting in the same room and the answer to scalability is to make bigger BINGO sheets or to allow people to solve the puzzle faster then you will most probably never understand what IOTA is working on. -------------------------------------------------------------------------------- HusQy **Blockchain does not work with too many equally weighted validators.****If 400 validators produce a validating statement (block) at the same time then only one can survive as part of a longest chain.**IOTA is all about collaborative validation. **Another problem of blockchain is that every transaction gets sent twice through the network. Once from the nodes to the miners and a 2nd time from the miners as part of a block.**Blockchain will therefore always only be able to use 50% of the network throughput. And****the last problem is that you can not arbitrarily decrease the time between blocks as it breaks down if the time between blocks gets smaller than the average network delay. The idle time between blocks is precious time that could be used for processing transactions. ----------------------------------------------------------------------------- HusQy I am not talking about a system with a fixed number of validators but one that is completely open and permissionless where any new company can just spin up a node and take part in the network. ------------------------------------------------------------------------ HusQy Proof of Work and Proof of Stake are both centralizing sybil-protection mechanism. I don't think that Satoshi wanted 14 mining pools to run the network. And "economic clustering" was always the "end game" of IOTA. ----------------------------------------------------------------------------- HusQy **Using Proof of Stake is not trustless. Proof of Stake means you trust the richest people and hope that they approve your transactions. The rich are getting richer (through your fees) and you are getting more and more dependant on them.**Is that your vision of the future? ---------------------------------------------------------------------------- HusQy Please read again exactly what I wrote. I have not spoken of introducing governance by large companies, nor have I said that IOTA should be permissioned. We aim for a network with millions or even billions of nodes. HusQy That can't work at all with a permissioned ledger - who should then drop off all these devices or authorize them to participate in the network? My key message was the following: Proof of Work and Proof of Stake will always be if you split them up via sharding ... HusQy ... less secure because you simply need fewer coins or less hash power to have the majority of the votes in a shard. This is not the case with trust in society and the economy. When all companies in the world jointly secure a DLT ... HusQy ... then these companies could install any number of servers in any number of shards without compromising security, because "trust" does not become less just because they operate several servers. First of all, that is a fact and nothing else. HusQy Proof of Work and Proof of Stake are contrary to the assumption of many not "trustless" but follow the maxim: "In the greed of miners we trust!" The basic assumption that the miners do not destroy the system that generates income for them is fundamental here for the ... HusQy ... security of every DLT. I think a similar assumption would still be correct for the economy as a whole: The companies of the world (and not just the big ones) would not destroy the system with which their customers pay them. In this respect, a system would be ... HusQy ... which is validated by society and the economy as a whole probably just as "safely" as a system which is validated by a few anonymous miners. Why a small elite of miners should be better validators than any human and ... HusQy ... To be honest, companies in this world do not open up to me. As already written in my other thread, safe money does not bring you anything if you have to assume that Volkswagen will beat you up and throw you out of the store after you ... HusQy ... paid for a car. The thoughts I discussed say nothing about the immediate future of IOTA (we use for Coordicide mana) but rather speak of a world where DLT has already become an integral part of our lives and we ... HusQy ... a corresponding number of companies, non-profit organizations and people have used DLT and where such a system could be implemented. The point here is not to create a governance solution that in any way influences the development of technology ... HusQy ... or have to give nodes their OK first, but about developing a system that enables people to freely choose the validators they trust. For example, you can also declare your grandma to be a validator when you install your node or your ... HusQy ... local supermarket. Economic relationships in the real world usually form a close-knit network and it doesn't really matter who you follow as long as the majority is honest. I also don't understand your criticism of censorship, because something like that in IOTA ... HusQy ... is almost impossible. Each transaction confirms two other transactions which is growing exponentially. If someone wanted to ignore a transaction, he would have to ignore an exponential number of other transactions after a very short time. In contrast to blockchain ... HusQy ... validators in IOTA do not decide what is included in the ledger, but only decide which of several double spends should be confirmed. Honest transactions are confirmed simply by having other transactions reference them ... HusQy ... and the "validators" are not even asked. As for the "dust problem", this is indeed something that is a bigger problem for IOTA than for other DLTs because we have no fees, but it is also not an unsolvable problem. Bitcoin initially has a ... HusQy Solved similar problem by declaring outputs with a minimum amount of 5430 satoshis as invalid (github.com/Bitcoin/Bitcoi…). A similar solution where an address must contain a minimum amount is also conceivable for IOTA and we are discussing ... HusQy ... several possibilities (including compressing dust using cryptographic methods). Contrary to your assumption, checking such a minimum amount is not slow but just as fast as checking a normal transaction. And mine ... HusQy ... In my opinion this is no problem at all for IOTA's use case. The important thing is that you can send small amounts, but after IOTA is feeless it is also okay to expect the recipients to regularly send their payments on a ... HusQy ... merge address. The wallets already do this automatically (sweeping) and for machines it is no problem to automate this process. So far this was not a problem because the TPS were limited but with the increased TPS throughput of ... HusQy ... Chrysalis it becomes relevant and appropriate solutions are discussed and then implemented accordingly. I think that was the most important thing first and if you have further questions just write :) HusQy And to be very clear! I really appreciate you and your questions and don't see this as an attack at all! People who see such questions as inappropriate criticism should really ask whether they are still objective. I have little time at the moment because ... HusQy ... my girlfriend is on tour and has to take care of our daughter, but as soon as she is back we can discuss these things in a video. I think that the concept of including the "real world" in the concepts of DLT is really exciting and ... HusQy ... that would certainly be exciting to discuss in a joint video. But again, that's more of a vision than a specific plan for the immediate future. This would not work with blockchain anyway but IOTA would be compatible so why not think about such things. ----------------------------------------------------------------------- HusQy All good my big one :P But actually not that much has changed. There has always been the concept of "economic clustering" which is basically based on similar ideas. We are just now able to implement things like this for the first time. ---------------------------------------------------------------------------------- HusQy Exactly. It would mean that addresses "cost" something but I would rather pay a few cents than fees for each transaction. And you can "take" this minimum amount with you every time you change to a new address. HusQy All good my big one :P But actually not that much has changed. There has always been the concept of "economic clustering" which is basically based on similar ideas. We are just now able to implement things like this for the first time. ----------------------------------------------------------------------------------- Relax오늘 오전 1:17 Btw. Hans (sorry for interrupting this convo) but what make people say that IOTA is going the permissioned way because of your latest tweets? I don't get why some people are now forecasting that... Is it because of missing specs or do they just don't get the whole idea? Hans Moog [IF]오늘 오전 1:20 its bullshitu/Relaxanidentity based system would still be open and permissionless where everybody can choose the actors that they deem trustworthy themselves but thats anyway just sth that would be applicable with more adoption [오전 1:20] for now we use mana as a predecessor to an actual reputation system Sissors오늘 오전 1:31 If everybody has to choose actors they deem trustworthy, is it still permissionless? Probably will become a bit a semantic discussion, but still Hans Moog [IF]오늘 오전 1:34 Of course its permissionless you can follow your grandma if you want to :p Sissors오늘 오전 1:36 Well sure you can, but you will need to follow something which has a majority of the voting power in the network. Nice that you follow your grandma, but if others dont, her opinion (or well her nodes opinion) is completely irrelevant Hans Moog [IF]오늘 오전 1:37 You would ideally follow the people that are trustworthy rather than your local drug dealers yeah Sissors오늘 오전 1:38 And tbh, sure if you do it like that is easy. If you just make the users responsible for only connection to trustworthy nodes Hans Moog [IF]오늘 오전 1:38 And if your grandma follows her supermarket and some other people she deems trustworthy then thats fine as well [오전 1:38] + you dont have just 1 actor that you follow Sissors오늘 오전 1:38 No, you got a large list, since yo uwant to follow those which actually matter. So you jsut download a standard list from the internet Hans Moog [IF]오늘 오전 1:39 You can do that [오전 1:39] Is bitcoin permissionless? Should we both try to become miners? [오전 1:41] I mean miners that actually matter and not find a block every 10 trillion years 📷 [오전 1:42] If you would want to become a validator then you would need to build up trust among other people - but anybody can still run a node and issue transactions unlike in hashgraph where you are not able to run your own nodes(수정됨) [오전 1:48] Proof of Stake is also not trustless - it just has a builtin mechanism that downloads the trusted people from the blockchain itself (the richest dudes) Sissors오늘 오전 1:52 I think most agree it would be perfect if every person had one vote. Which is pr oblematic to implement of course. But I really wonder if the solution is to just let users decide who to trust. At the very least I expect a quite centralized network Hans Moog [IF]오늘 오전 1:53 of course even a trust based system would to a certain degree be centralized as not every person is equally trustworthy as for example a big cooperation [오전 1:53] but I think its gonna be less centralized than PoS or PoW [오전 1:53] but anyway its sth for "after coordicide" [오전 1:54] there are not enough trusted entities that are using DLT, yet to make such a system work reasonably well [오전 1:54] I think the reason why blockchain has not really started to look into these kind of concepts is because blockchain doesnt work with too many equally weighted validators [오전 1:56] I believe that DLT is only going to take over the world if it is actually "better" than existing systems and with better I mean cheaper, more secure and faster and PoS and PoW will have a very hard time to deliver that [오전 1:56] especially if you consider that its not only going to settle value transfers Relax오늘 오전 1:57 I like this clear statements, it makes it really clear that DLT is still in its infancy Hans Moog [IF]오늘 오전 1:57 currently bank transfers are order of magnitude cheaper than BTC or ETH transactions Hans Moog [IF]오늘 오전 1:57 and we you think that people will adopt it just because its crypto then I think we are mistaken [오전 1:57] The tech needs to actually solve a problem [오전 1:57] and tbh. currently people use PayPal and other companies to settle their payments [오전 1:58] having a group of the top 500 companies run such a service together is already much better(수정됨) [오전 1:58] especially if its fast and feeless [오전 2:02] and the more people use it, the more decentralized it actually becomes [오전 2:02] because you have more trustworthy entities to choose of Evaldas [IF]오늘 오전 2:08 "in the greed of miners we trust"
Author: Gamals Ahmed, CoinEx Business Ambassador https://preview.redd.it/5bqakdqgl3g51.jpg?width=865&format=pjpg&auto=webp&s=b709794863977eb6554e3919b9e00ca750e3e704 A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it. Filecoin announced, that there will be more delays before its main network is officially launched. Filecoin developers postponed the release date of their main network to late July to late August 2020. As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process. Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market. Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors. The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020. They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit. The Filecoin team noted the following: “We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks. Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet. The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020. The updates to the project can be found on the Filecoin Road Map. Filecoin developers stated: “This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage. Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain. In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards. Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21. Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price. Mining in Filecoin In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency. Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data. Filecoin will contain several types of miners: Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out. Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power. Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network. The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into. In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.
The current system specifications recommended for running the miner are:
NVIDIA-manufactured GPU (to be expanded).
SSD drive designated as large buffer (512GB +).
Large amount of RAM for data replication account (128GB +)
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars. Proceed to mining Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract. Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually. After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started. Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page. At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention. Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt. Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network. Duration of operation, cutting and penalties “Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network. In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error. Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily. An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection. The sector will pay an error fee after the penalty of the sector once the error is discovered. Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network. Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function. Filecoin miners Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.” With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices. Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless. Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers. Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network. However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners. These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB). Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development. “Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital. “Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said. Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT. In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive. To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day. As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force. The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million. This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs. After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020. The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process? Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance. In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners: The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue. It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown. It seeks to promote mining using Filecoin Discover Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day. Ian Darrow, Head of Operations at Filecoin, commented on the announcement: “Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”. Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more. Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds. In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations. The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested. “The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”. IPFS and Filecoin Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure. IPFS It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live. The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides. Using IPFS In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data. Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service. Using Filecoin The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone. Filecoin, powered by IPFS It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS. Some advantages of sharing Filecoin with IPFS:
Filecoin and IPFS CIDs share hash specifications.
Use libp2p by Filecoin nodes to create secure connections with each other.
Messaging between nodes and cluster propagation is facilitated in Filecoin by libp2p pubsub.
IPLD use for blockchain data structures.
Use Graphsync to transfer data between nodes.
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol. Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated. PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage. In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected. Resources :
Multi apartment clustered cryptocurrency mining rig
So you’ve probably just heard all your classes are online. And now you’re trying to sublet your apartment but no one’s gonna take it. So now you’re gonna be paying at least $1000/month for an empty apartment. I have a proposal that can reduce that cost and possibly turn a profit. Firstly, we have a very high risk credit market on our hands. The Federal Reserve has been pumping money into the economy and at some point the US dollar will have to inflate while growth stagnates (aka stagflation). During stagflationary periods in the past the price of non-fiat currencies like gold or silver has skyrocketed. Recently cryptocurrencies have emerged with the same general economic properties of such commodities. Therefore we may see an increase in their values as the Fed keeps pumping more money into the economy. As of now in order to generate enough money per month to pay off rent in South Campus Commons, each apartment would need a Bitcoin rig capable of generating ~2200 TH/s (since you don’t pay for electricity). For the Varsity and View this might have to be higher considering the cost of electricity. This is definitely possible with new ASIC chips that are solely built for the purpose of running Bitcoin hashing algorithms. For other cryptocurrencies (Ethereum, Litecoin, Dogecoin), these rates may be different. But like any good portfolio manager, diversifying our investments will ensure we have a profitable outcome. If enough students come together to construct a Bitcoin mining rig in their apartments we could essentially create a multi apartment clustered miner to be able to generate Bitcoin. On top of that, because campus server resources will be diminished due to online classes, we can in turn utilize that computing power to help mine such cryptocurrencies. As a result we won’t have to find people to sublet our apartments to and won’t have to worry about the financial undertakings associated with it. TL;DR: Corona collectively fucked everyone in the ass and we should build a massive Bitcoin rig to pay off our rent.
08-10 07:44 - 'Who is forking Filecoin?' (self.Bitcoin) by /u/paulcheung1990 removed from /r/Bitcoin within 6-16min
''' Forking Filecoin is a $500 million to $1 billion business? On July 17, cryptocurrency analyst Bitfool mentioned via Weibo: “Recently, people who forked Filecoin in the market have been undercurrents; as far as I know, there are 4-5 teams. From a strategic point of view, the project Teams, investors, and miners get two of the three to successfully fork; one of the three can steal 5-10% of the market value. Therefore, Filecoin's fork is a $500 million to $1 billion Business." "It's even more awesome, full of courage, and ready to build a team to fork Fliecoin. Well done, famous in the world, poor done, and scorned by thousands of people." Sun Ming, a partner of Fenbushi Capital, mentioned in an interview: "Miners who have invested a lot of hardware resources are promoting the fork of Filecoin. Hu Feng, operating partner of the FILPool mining pool, said: "Currently, big miners have ideas, but it will only be possible after the mainnet is online. Filecoin economic model is not friendly to miners At the beginning of the establishment of the Filecoin economic model, a pledge and reward and punishment mechanism was proposed, which has undergone many adjustments. The last three adjustments have made the mechanism increasingly stringent. In April of this year, the Filecoin project team introduced their thinking on the economic model and refined the reward and punishment mechanism. Miners who complete file storage can get corresponding block rewards, and fail to store files within the promised period will be punished. This fine is imposed on the Filecoin collateral pool (locked funds) provided by each storage miner. Locked funds include a small amount of early FIL tokens and token rewards obtained from miners. Miners need to mortgage a certain amount of tokens in the early stage. If the amount of mortgage is too large, it will cause a shortage of FIL tokens in the early stage. The improvement made by the economic model is to transfer some of the early-stage costs to future block rewards. The severe punishment mechanism made some miners dissatisfied, and some miners commented that the mechanism was too "crude". In May, Filecoin made major adjustments to its economic model. This adjustment raises the threshold for miners to leave. Filecoin continues to strengthen the miner's mortgage mechanism, and part of the rewards mined by the miners will be locked. The penalty mechanism has also been changed accordingly. Only when the task of file hosting is completed can the mining reward be unlocked. If miners want to profit, they need to have strong computing power and be able to provide stable storage services for a long time. If this is acceptable to miners, the recent "pre-mortgage" mechanism has left miners at a loss. "Pre-mortgage" is proposed in the latest Calibration version of Filecoin, which means that every sector encapsulated requires a certain amount of FIL to be pledged in advance, and the pledged token needs to be locked for 180 days and then released in 180 days. The consequence of "pre-mortgage" is that FIL token has worse liquidity in the early stage. A large number of FIL mortgages are required in the early stage, which will force miners to find the official to buy coins, and the long lock-up period causes most miners to choose to sell coins instead of encapsulation. "The miners have put their money in the hardware, where can they go out and buy coins?" Since there is not enough funds to buy coins as collateral, it loses the qualification for mining. Even if the mortgage funds are saved, it is almost impossible to pay back with the small amount of currency in the early period. Sun Ming said: "The mining output is too small, making it difficult for early miners to maintain operations." The adjustment of the economic model continues to compress the income of early miners, and the voice of miners proposing to fork Filecoin is also getting louder. Sun Ming believes: "On the one hand, it is the protest of the miners against ProtocolLabs (requesting it to modify the economic model), and on the other hand, it is also the desperate fight of the miners forced to do nothing." Li Bai posted a circle of friends to express his attitude. As shown below: [link]1 Another very important point is that, according to the current reward mechanism, Filecoin competition in China is tantamount to "college entrance examination". Take the Filecoin big miner test competition as an example, miners can only be rewarded if they are ranked in the top 50 in their area or in the top 100 among all miners. Looking at the situation of Chinese miners, 9 of the top 10 nodes in the world are from China. According to people familiar with the matter, about 80% of Filecoin miners are concentrated in China. The fierce competition can be imagined. Wang Qingshui expressed his concern: more than 90% of miners may not make money. Many miners saw that they couldn't make money, and they had the idea of opening up Filecoin "other tracks". Therefore, the call for a Filecoin fork is the strongest in China. Unaffordable mining costs and thresholds In addition to Filecoin's economic model, another point that miners complain about is Filecoin's threshold and cost. The cost of Filecoin mining input and the technical threshold of operation are beyond the reach of many miners and mines. Filecoin has a severe punishment mechanism, which can ensure the safety of the data party, but at the same time it will bring a high threshold for mining professionalism and operation and maintenance stability. In order to ensure uninterrupted power and no disconnection, it must be hosted in a high-level IDC computer room. In order to ensure mining efficiency, the network, computing power, and storage hardware must not be poor. Therefore, miners need to use a large sum of money to purchase high-end hardware equipment. Instant window-POST verification and submission requires high algorithms and error repair capabilities, and requires professional algorithms and operation and maintenance teams. In addition, the threshold for Filecoin mining may be above 10TB or even higher. Entry mining has a threshold for storage and technical maintenance, and a lot of money is needed to purchase hardware equipment. Earlier, a blogger did a cost calculation. With 30 mining machines as a cluster calculation, the expenditure for purchasing mining machines alone was as high as 6 million. Coupled with the cost of computer room construction, operation and maintenance, Filecoin mining costs may be more than 10 million yuan. Wang Qingshui also mentioned the flaws: “Many ordinary miners and even servers cannot participate, which is contrary to the original intention of the project.” Some people in the community expressed their concerns: "I have invested so much. What if something goes wrong after Filecoin goes online? Wouldn't it be a loss?" So some miners are thinking, can they lower the threshold of mining while ensuring safety? Some miners pointed out that not all mining machines need to be hosted in the IDC computer room, which is costly and prone to waste of resources. If it can be hosted in different computer rooms according to the performance of each type of mining machine, it can not only ensure safety, but also reduce costs. Judging from the interview, many industry insiders are on the sidelines of the Filecoin fork. Li Bai said: "There are many people who have ideas, but few people can put them into action." Wang Qingshui believes that any popular big project will be forked. Are BTC and ETH forked less? But how many forks can surpass the original version? Some miners think that the fork is just talking: "Someone will follow the official game.", "Who wrote the code for you after the fork? Do you dare to use the code you wrote?" The Filecoin fork is "undercurrent". As the Filecoin mainnet approaches, miners' actions will become more frequent, and we will continue to report. What do you think of the Filecoin fork? Please let us know in the comments section. ''' Who is forking Filecoin?

Bitcoin mining may be a senseless waste of energy. As bitcoin hits mainstream media, the subject of bitcoin mining bubble regarding to pop.For ten years, the media has enjoyed painting bitcoin as a bubble concerning to pop. They’ve gleefully pronounced the bubble popped and bitcoin dead … over 350 times. However the reality regarding bitcoin is that it keeps coming back back. Why? Charlie Munger called bitcoin “worthless artificial gold.” Others in the media have likened bitcoin to a bubble, a “tulip mania,” and different strong statements Each time bitcoin improves itself (like with Segwit Segregated Witnesses. A protocol implemented by Bitcoin to extend transaction speed. SegWit allows a lot of transactions to be written into a single block on a blockchain. or the Lightning Network), or will increase in value, the media is keen and ready to jump on it, decrying and denouncing it. Therefore what’s the reality behind bitcoin’s price -- is it extremely a bubble? The reality regarding bitcoin is straightforward; it's experiencing the same rise and fall cycles as each new technology and asset catego The web also experienced a bubble. Shares of dotcom firms rose by a thousandpercent on a daily basis. Then it all tumbled down. However we have a tendency to’re still using the web, aren’t we have a tendency to? More than ever, in fact. Stocks conjointly experienced big boom and bust cycles, especially in their early days. We might feel like stocks have been around forever -- and to us they need. However stocks conjointly had a starting, and a rough one too. Once upon a time in 1531, when the first stocks were invented, they saw extraordinary volatility, scams, and no regulation. In fact, before stock exchanges, they were sold at occasional shops -- just like cryptocurrencies were sold on la peer to peer marketplace, before exchanges came online. Even property, viewed by the majority as “the safest investment” experienced a dramatic cycle. Business Insider reported that “Between 2006 and 2014, nearly ten million homeowners in America saw the foreclosure sale of their own homes.” And tens of thousands became homeless as a result of of it. Nevertheless --- we have a tendency to’re still living in homes, aren’t we? The future of bitcoin would possibly be the identical as that of stocks, bonds, assets, and the web. It rises and falls like all the others, and it is currently terribly volatile -- but that’s as a result of it’s young. Stocks have been around for 400 years. Dotcom corporations for forty years. Bitcoin is solely 10 years previous -- and cryptocurrencies, normally, are even younger. But slowly, they will become a part of our daily lives. Rich investors are manipulating costs! Look at this headline from the Independent: “Bitcoin price Crash: 'Manipulative Whales Whale A very wealthy individual capable of creating massive trades. View full glossary ' cause Cryptocurrency Market Meltdown!” It’s sensationalism, pure and straightforward. The article goes on to rant against these therefore-known as “whales” -- individuals who own voluminous dollars of BTC -- as evil-doers who’s solely thought is profit. This type of sensationalism is meant to harm Bitcoin’s future; to scare people faraway from doing research and thinking for themselves. Nonetheless, this statement is somewhat true. Up to eighty five% of Bitcoin’s supply is solely owned by onepercent of wallet addresses. But there’s an important point to be made about these numbers. Most of the prime percentage of wallets is not owned by whales -- but by exchanges Exchange On-line platforms on which people can buy and sell cryptocurrencies. View full glossary . However their result is getting smaller and smaller. A company referred to as Chainalysis -- that makes a speciality of analyzing the Bitcoin blockchain -- found that “the actual threat that all whales pose to the cryptocurrency economy is relatively low. If they sold off their entire holdings, it'd be effectively a $3.9 billion sale at current costs. That’s not even tenpercent of this total market capitalization of Bitcoin.” This is as a result of, as I hinted above, several of those wallets holding such vast sums are the ‘cold wallets ’ (wallets held offline) belonging to major exchanges like Coinbase, Kraken, Binance, and more. These wallets cannot be used to manipulate the price, diminishing the potential impact of enormous ‘whales’ selling their positions. Bitcoin is simply too slow for use as a currency. The reality regarding Bitcoin is that yes, it's slower than VISA, Mastercard, and alternative centralized electronic payment systems. Paying together with your credit cards takes seconds and the network can handle payments around the globe twenty fouseven. But, though Bitcoin can additionally be used around the world, confirmation of payment takes an average of 10 minutes; during the bitcoin craze recently 2017, confirmation times might take hours. Moreover, VISA on average processes around 2,00zero transactions per second (tps). This means the amount of payments individuals make per second on the network. VISA includes a maximum of twenty four,00zero TPS. Bitcoin, by distinction, has a maximum of ten TPS. This argument has been place forward by several critics over the years and picked up by the media as the doom of bitcoin’s future. However Bitcoin could be a technology that evolves. Now let’s assume regarding Bitcoin’s past for a moment. The coin and its underlying technology -- the blockchain -- are only ten years previous. When the web was ten years old -- the year was 1989. Do you keep in mind the net in 1989? I sure do. payments in exchange for not revealing sensitive info. So, in bound ways that, BTC and cryptocurrencies offer hackers a lot of options. However money continues to be king for every criminality. Though it’s true that hackers and phishers do typically ask for payment in BTC There’s an aphorism: “money talks.” It means that that if you would like to get something done -- the best argument you can build is to place down a stack of money. When Bitcoin rose to fame, the primary headlines focused around Bitcoin being the prime choice for criminality. But Lilita Infante, Special Agent for the DEA (Drug Enforcement Administration) has some contradictory info regarding this. She was one among a ten-person Cyber Investigative Task Force team whose primary aim was the dark web and crypto-related investigations. This cluster is no little force. They collaborate with the Department of Justice, FBI, and also the Bureau of Alcohol, Tobacco, Firearms and Explosives. And she went on the record to talk regarding what share of bitcoin transactions are literally being employed for illegal things; she said that “illegal activity has shrunk to about 10 p.c.” Only tenp.c of all the transactions on the Bitcoin network could be used for illegal things. Which number is falling. The fall in Bitcoin’s use among criminals is due to several factors. The most prominent factor is that Bitcoin is no longer anonymous. Sciencemag wrote a full report on how governments are developing and using techniques to explore the Bitcoin blockchain and notice criminals by tracing their bitcoin payments. Paying with bitcoin isn’t simple. I’ve heard this argument flow into widely throughout the years. I still hear it from my grandpa each vacation dinner. He didn’t see a Bitcoin checkout option at the grocery when he bought the turkey -- therefore it’ll never be used. Perhaps Bitcoin is on its means to being such a store of worth. For 10 years now bitcoin has been ready to be saved and retrieved and exchanged -- and it’s worth has only gone up (bumpy but up). Need to get more cryptocurrencies? Check out our top 5 cryptocurrencies to shop for, whether you’re a beginner or an experienced investor! Bitcoin is difficult to use. Bitcoin, like all new technologies, isn't the most user-friendly. You would like to line up a wallet, bear in mind a seed phrase, and several additional steps. Sending and receiving BTC payments additionally involves steps of copy/pasting long strings of random letters and numbers. It’s powerful, I hear ya. I additionally keep in mind all the steps I needed to require to send emails back when those were new. Insert a CD from AOL into my computer. Install AOL. Unplug my phone line. Plug in my Modem. Wait for it to make all those noises and finally connect. Then set up my AOL email and password. It was quite the method. My grandfather never thought emails would come out and even my mother said folks would perpetually like handwriting letters (and using a physical dictionary for spell check!) and sending through the post. Think about it the approach we tend to assume about gold. Not everyone has gold. It’s also a bit difficult to own. If you wish to own gold for its ‘store of price’ properties, you wish to seek out a specialized look to buy investment gold. You need to store it somewhere, sort of a personal safe or a bank vault, and bear in mind the password.

2/6 Disclaimer: This is my editing, so there could be some misunderstandings. Anyone who wants to read everything should go to the 'spec' of Paracosm discord. IMHO, Hans's philosophy and motivation is worth sharing widely. Hans Moog [IF]어제 오전7:57 People are more motivated then ever Hans Moog [IF]어제 오전8:02 the point is that the IF is not going to be there forever - its not meant to having a self sustainable ecosystem is very important for the maturity of the protocol Hans Moog [IF]어제 오전8:03 No it's not if IF would cease to exist tomorrow - it would be finished by the people working for the IF anyway I am 100% sure and if i would have to do it alone ... Hans Moog [IF]어제 오전8:05 we can all do it together - and we are actually doing it already hornet and goshimmer have VERY close ties they are really good friends and very capable coders its an honor to work with them Hans Moog [IF]어제 오전8:06 [when do you reckon the shift to binary will take place?] its being merged in goshimmer tomorrow :smile: Hans Moog [IF]어제 오전8:14 [about Multiverse] the last statements of popov was that it "might work" he still has some concerns i guess he still tends to think the chances of it not working as bigger than the chances of it working I am 100% sure it works - but maybe its on me to prove that with a fully functional prototype. Hans Moog [IF]어제 오전8:17 My goal is to show a prototype being able to process 10 million tps by the mid of this year - we will see if I can pull this off maybe time will be rare, considering the parallel work on coordicide maybe I should aim for end of 2020 instead Hans Moog [IF]어제 오전8:19 of course it includes sharding that whole point of IOTA is sharding and a completely new form of sharding Hans Moog [IF]어제 오전8:19 [why 10m TPS?] its just a random number some kind of goal post so you can process the entirety of bitcoins history in 1minute and 30 seconds? would be a nice thing Hans Moog [IF]어제 오전8:21 coordicide and multiverse would essentially use the same sharding principles I hope that we can share more on that soon Oh its quite concrete we are starting to write math papers about it already Hans Moog [IF]어제 오전8:23 FPC is perfectly fine for sharding you have to forget the discrete sharding world of blockchains where you just make n copies of the same thing its very different Hans Moog [IF]어제 오전8:30 I would LOVE to share that with you but maybe just wait a but longer - we will be more open about this pretty soon let's just say that we still have some aces in our sleeves Hans Moog [IF]어제 오전8:49 nope I am completely new in crypto but I am pretty sure that some people might "know me from before" if they would know what I did before Hans Moog [IF]어제 오전8:57 dude the IF has reached a stage where it would survive without anbybody I could drop dead tomorrow and the IF would continue, same goes for David or anybody else Hans Moog [IF]어제 오전9:00 all the corporates and everything ... it might not be fully reflected in the price yet but IOTA has a really really bright future Hans Moog [IF]어제 오전9:01 I think we are starting to see a pretty bullish sentiment around IOTA lately I only hope that its due to our increased transparency with a clear roadmap and everyhting, and not just some random fluke in the prices It would just feel much more "rewarding" to be a consequence of our efforts :joy: Hans Moog [IF]어제 오전9:05 i am buying more IOTA every month : was very happy about the low prices but I can understand that if you just "have to believe" and have no insight about the actual progress, then these prices can feel more concerning than a "bargain" Hans Moog [IF]어제 오전9:13 Do you really expect a guy working on IOTA to not be bullish about the tech and everything? I am not in IOTA for the moneyzzz Hans Moog [IF]어제 오전9:18 if you are asking for investment advice, then I am most probably the worst person to ask as my trades in crypto have always been horrible Hans Moog [IF]어제 오전9:20 I didn't have the chance to be around in the ICO days so I need to take what's left Hans Moog [IF]어제 오전9:27 I don't know man - everybody that I know is not willing to sell Hans Moog [IF]어제 오전9:35 Yassin is the proof that "reputation" is worth something A man of honor - my deepest respect to you man People who stick to their word and can be trusted are sadly a rare thing in today's world Hans Moog [IF]어제 오전9:39 I anyway think that we have way too much tribalism in crypto people should really stop praising "people and projects" and instead start to praise ideas and concepts Hans Moog [IF]어제 오전9:43 I mean I get the whole concept of having a single currency and shit, but if the tech is bad? I mean this is the first time in the history of humans that we can "design" the very foundation of our social and economical layer why would we not go for the best available tech? bitcoin was "a breakthrough" when it was released and it helped to kickstart a whole field of research but its clearly not the best possible solution Hans Moog [IF]어제 오전9:47 ultimately the best tech will win just look at bitcoins dominance its fading long term sure it was time for a correction from the 2017 run of alts Hans Moog [IF]어제 오전9:47 but the overall trend is pretty clear bitcoins days are numbered Hans Moog [IF]어제 오전9:54 maybe I can leak one thing about IOTA's sharding solution without giving away too much: Every single node can individually decide how much data it wants to process - so you can have very very resource-constrained nodes like sensors and stuff in the same network as nodes with hundreds of cores and they will be able to work together seamlessly there will essentially be no "minimum hardware requirements" for a node (of course you have "some" requirements to even be able to run some kind of logic) Hans Moog [IF]어제 오전9:56 We are on the forefront of research when it comes to VDF's but its not really related VDFs would maybe be a way to replace PoW in the future as a rate control mechanism Hans Moog [IF]어제 오전9:58 you don't need big nodes you can be as big as you want to be but naturally some nodes will have more power than others Hans Moog [IF]어제 오전10:01 possible - the whole mana system is based on "reputation", if you run a reliable cluster of nodes that people are willing to use, then you can earn mana and since mana decides how many transactions you can issue, you can of course "allow others to use your resources" for money so operating a reliable node cluster could be sth that people might do "for a living" in the future maybe it would be best to build up a reputation already today Hans Moog [IF]어제 오전10:03 if you have funds in the network, then you will generate more than enough mana to have enough "shares" in the network to use it for free but if anybody wants to just piggyback on the network without holding tokens, then he might have to pay a "fee" Hans Moog [IF]어제 오전10:05 if you want to send a lot of data transactions, then you better have some tokens I mean its just fair, right? you don't have any stake in the network but you wanna use it? then pay for it but people who have funds in the network can use it for free Hans Moog [IF]어제 오전10:07 i think ultimately the community will provide a plugin for the nodes, where you can "automatically" rent your excess reputation for some income Hans Moog [IF]어제 오전10:08 [what would the income be ?] tokens IOTA Hans Moog [IF]어제 오전10:09 by the people who want to use the network more than what their token holding would allow them to so they rent "mana" from the people who have it Hans Moog [IF]어제 오전10:10 the internet took off when flat-rate emerged and prices became predictable the same is true for crypto Hans Moog [IF]어제 오전10:11 thats why companies like IOTA so much ... it creates a platform that has "predictable" prices any mining based crypto will never be able to offer the same Beeing feeless is not just a "funny feature", its the key to mass adoption Hans Moog [IF]어제 오전10:14 If I run a node and have funds in the network, then why would I pay anybody anything? I am supporting the network already by using it Hans Moog [IF]어제 오전10:16 Yeah we are using "mana 2" now which is also the one that is implemented in the goshimmer mana package the formulas are going to change a bit tho we had like 16 different versions of mana with all very different implications on game theory and code Hans Moog [IF]어제 오전10:18 but serguei is the expert when it comes to game theory and we are pretty confident that we have chosen the correct survivor Hans Moog [IF]어제 오전10:19 [The mana implementation does seem like the slipperiest slope] it uses a few economic theories from the early 20th century (from silvio gesell) by having smth like a "demurrage function" so the rich dont get richer its software - if any design decision turns out to be problematic, you patch it Hans Moog [IF]어제 오전10:20 [So it’s hard to maintain a high mana] its not like you have to live with it for thousands of years like in our current FIAT system if you make it right from the start, the rich will never become that powerful that they could even dare to fork Hans Moog [IF]어제 오전10:22 you are "RENTING" out your excess resources that doesn't mean that you will broadcast everything unseen If somebody tries to use your node to perform an attack you will just ignore it of course you might "lose the fees" that they would be willing to pay you to perform this attack, but ultimately you will have to decide what is more valuable to you the few cents of IOTA you earn or your "reputation / mana" Hans Moog [IF]어제 오전10:25 the nodes will perform all of the sanity checks, so they don't "accidently" take part in an attack of course the point is that its a voting system based on mana if I use your node to "issue a transaction", then I maybe pay you for issuing this tx but your "opinion on that tx" is independent of that Hans Moog [IF]어제 오전10:29 actually I even think that the whole coordicide principles especially in connection with the sharding are very much in line with cfb's initial vision - and I am actually a bit sad that he never really dared to honestly look into them Hans Moog [IF]어제 오전10:29 I was even thinking about "naming" the multiverse "cfbs vision" once maybe its more (pauls's vision) than cfbs vision paul handy was one of the other early developers of IOTA btw. and a very very smart person I have to say a lot of the ideas that we are currently pursuing go back to his line of thinking Hans Moog [IF]어제 오전10:32 the infamous "ontology principles" the ultimate goal is to be able to run "anything" on the tangle - not just value transfers but literally anything, event remotely related to DLT's I envision IOTA being a general purpose DLT platform pretty much like TCP/IP was for the internet Hans Moog [IF]어제 오전10:36 I introduced "broadcasts" a few days ago as a new concept that is the equivalent of UDP messages Hans Moog [IF]어제 오전10:49 I think that one of the things where cfb and me disagree regarding the "vision of IOTA" is that he think thats we should "finalize" the protocol as soon as possible (or "set it in stone" as he likes to call it), so hardware manufacturer can start to build hardware, whereas I think that it makes much more sense for it to be something like an "open evolving standard" that is so flexible that you can literally build whatever the fuck you want based on this protocol. The internet wouldn't have been the internet, if it would have "just" been for sending scientific messages between researchers. I can not anticipate and know what humans might do with DLT in the future, so limiting myself to "only value transfers" is IMHO the wrong decision. for something to be successful, it needs to be able to "model" everything that could possibly exist Hans Moog [IF]어제 오전10:51 IOTA will be able to run "anything" on top of it - even "virtual instances of other cryptocurrencies" and its not going to be some quirky slow emulation - it would most probably even be faster and more reliable than when being implemented without it Hans Moog [IF]어제 오전10:52 similar to "INTEL inside" you will most probably see sth like "Tangle inside" soon Hans Moog [IF]어제 오전10:54 "any application" running on top of the tangle (MAM, DID, Qubic, Matrix ... you name them) would ALWAYS have to be able to process IOTA value transfers THAT's what will give the token a value Hans Moog [IF]어제 오전10:55 if everybody can already "speak the same language" anyway, then people will also use that language to communicate which means that people will use the IOTA token to transfer value so we don't need to "force ourselves" on others - they will come by themselves because its the only thing that makes sense Hans Moog [IF]어제 오전10:57 [so Hans, $10 EOY still ?] if btc stays where it is? hard to achieve i'd say most probably not it always takes some time for people to "wake up" dunno maybe it goes fast most weak hands are gone in IOTA Hans Moog [IF]어제 오전11:00 But seriously guys ... the price of course is interesting but if we are able to pull this off, then this will be the start of a new form of society it will affect everything the way we interact .... even the way we behave towards each other I am not even sure if you need to be "rich" in that kind of society Star trek sounds like a nice vision Hans Moog [IF]어제 오전11:20 [once IOTA is completely implemented, its gonna be a matter of energy consumption optimization race I guess?] ultimately, yes whatever crypto is going to be the "cheapest" one to "operate" will win Hans Moog [IF]어제 오전11:22 BUT that is at the same time "expressive" enough to not have "niches" for weird competitors, that claim to be even a "little bit better" in one of the aspects it needs to be the best possible solution that humans are most probably able to come up with Hans Moog [IF]어제 오전11:23 if even the smallest something can be improved, then it should become part of the core rather than a competing project not having miners and being able to "upgrade" whenever it is necessary, is what will give IOTA power not setting stuff in stone today Hans Moog [IF]어제 오전11:29 I guess what fascinates me the most about IOTA is that people have a different kind of philosophy - in crypto people are usually sharing the mindset of "let's destroy the banks ... or .... the FED ... or whoever they consider to be their enemy IOTA for me is not so much about "destroying somebody else" rather than "creating something new" Hans Moog [IF]어제 오전11:30 But the "mindset and motivation" makes all the difference And I feel like large parts of the community "understand and share" that vision Hans Moog [IF]어제 오전11:34 there are plenty of "problems" where DLT is not the right answer but there are most probably also quite a few that we haven't even thought about, yet that go way beyond just "finance" Hans Moog [IF]어제 오전11:38 [Has IF any plans for anonymous transactions Hans?] it's current not our main point of research but I would say ultimately yes the fact thats its feeless make "mixing" funds a very feasible solution But even on top of that (like zero knowledge proofs and stuff) If there is a use case, then you should be able to do it with IOTA. that's what I mean with "general purpose DLT" platform whatever is possible should be doable with the protocol - not "just" IoT value transfers Hans Moog [IF]어제 오전11:42 everything you could most probably think of the same way as TCP/IP allows you to play computer games, send emails, or watch streams Hans Moog [IF]어제 오전11:48 tomorrow I start merging the first ledger-related stuff into the development branch from the outside it will most probably look like any other day : but starting to work on the "final version" which is supposed to be ready end of Q1 is a big milestone for us 2 months left Hans Moog [IF]어제 오후12:04 100% agree - let's finish this shit! we have "talked" for quite a while - the coming months, we will have to show what we "have"
It is a good time to reflect on the departure direction of DeFi
https://preview.redd.it/7qgmezggsnj51.png?width=700&format=png&auto=webp&s=af548c50ffe0568e2c49c6de1f14e298ae8a4ee3 In which direction should DeFi develop in the next step? The market is changing dramatically. The past few days have been like riding a roller coaster. But after several rounds of fluctuations, the DeFi segment in the stock market is still unabated. However, the hidden worries lurking under the surface are always existing. Almost all resources in the DeFi ecology are on Ethereum. However, there are problems with the DeFi network built by Ethereum, such as the single system performance brought by the foreseeable homogeneous sharding in the future, high gas fee, low security, and low scalability, etc. These vulnerabilities make the many applications hard to use on the DeFi network, including high-frequency trading and the transaction matching modes (We use the Uniswap asset pool model today.) The problem with ETH1.0 is that the performance is limited, and all the transactions are mixed without any organization. Although there is composability for the DeFi applications, the network needs to operate both DeFi applications and other transactions or DApps.
Network congestion and skyrocketing gas fees
As we all know, Ethereum relies on the consumption of GAS to run its economic operation. Every step of the chain requires the consumption of GAS. Bitcoin plummeted by almost 50% to $3,800, and ETH fell as much as 65.2% just on March 12 and 13, 2020. The plummet caused a run, the Ethereum miner fees that carried a large number of DeFi and DApps skyrocketed, and the network was also congested. The Ethereum GAS fee increased to 10 times of the usual, and the GAS fee was once as high as 1 ETH to successfully package transactions. After that, because the lending operations of DeFi applications require frequent interaction with contracts, the gas fees on Ethereum have also remained high.
Problems inherited from ERC20 tokens are affecting the DeFi products on Ethereum.
If you use Ethereum’s native token ETH, the operation is simple. As long as the ETH is transferred to the contract of the target DeFi application, the contract operation will be the same as when we use cash to invest in stocks or wealth management products. No other operations are required. However, the operation of tokens minted using ERC20 contracts is very different from native ETH, regardless of whether the tokens minted by these ERC20 contracts are well-known. Before trading, the ERC20 contract first authorizes the DeFi platform’s contract to transfer a specified number of ERC20 tokens on the account, such as USDT, USDC, or WBTC. After approval, the DeFi contract is called to transfer money. The intuitive understanding is to avoid frequent password input in small transactions, we authorized Paypal to open a password-free payment, so that the payment can be directly deducted during consumption. It sounds convenient, but is it that good? There is a crucial problem here: if the DeFi contract is malicious during the approval process, this DeFi contract has the right to transfer all the ERC20 tokens on our account to any account. It is similar to that we authorize Paypal to perform a password-free operation of the balance, but if a hacker attacked Paypal successfully, this hacker could transfer all our money to his account. Similar things have happened before. There is a famous project called Bancor, which used to rely on the type of authorization contract for ERC20 processing. However, there was a bug in the contract that allowed the contract to transfer the tokens in the user’s wallet to any hacker designated address after the user was authorized, which caused a loss of almost 100,000 US dollars. The loss was not so significant because it occurred in the early stage of DeFi development. If it happens today that the DeFi asset scale on Ethereum already reached hundreds of millions, it would cause severe damage to the entire Ethereum ecosystem and the development of DeFi.
Cold shard and hot shard
DeFi needs composability, convenience, and a stronger capability of anti-run. If the throughput is insufficient, sharding technology can be introduced, which is what ETH2.0 does. However, due to the combinability of DeFi, these applications tend to aggregate into one shard, which is prone to clustering effects. This will result in different shards gathering different contents. This is called hot shards and cold shards, which are analogous to different types of cities such as metropolises as New York and Tokyo, and other places like Kyoto and Alaska. Some places have become Wall Street, while other places may become scenic or living areas. Because of the aggregation of different functions, different shards will have different features. It is quite unwise to develop algorithms to forcibly redistribute load balancing on shards. This is equivalent to using a simple system to determine the development of a complex system, much like a planned economy. However, we can design different features in advance to make them more capable to display their own features, just as humans transformed and utilized the natural resources based on their understanding of nature, thereby improving efficiency. That means, to set up some shards with different performance and even different consensus algorithms (e.g., the features of PoW and PoS are different). Maybe there will be a major financial shard, like London, or two other special shards with their own features, like New York City and Chicago. Financial shards require high throughput and high cost. These are called hot shards, which carry large-value transactions, otherwise, the gas fee may be too high. Most people will live in the countryside, which means cold shards here. When you need the hot shard features, you don’t need to live in Manhattan, nor do you need to travel to Manhattan occasionally. Most of the time, you will live well on another shard. When one really needs to run on a DeFi shard, it only takes a few minutes of cross-shard transactions. But the problem generated from this is that since each shard has its own features, it may cause the shards to be independent. What we need is that shards can be harmonious but keep their differences, that is, cross-sharding DeFi needs to be achieved. Today’s multi-chain heterogeneous technology can contribute to solving this problem. Only by solving these problems can more DeFi applications be stimulated. In our opinion, a mature DeFi platform must have the following features: Higher Efficiency: Have faster concurrent processing capabilities, i.e., high TPS. Lower Gas Fee: Lower gas fee can stimulate the enthusiasm of DeFi users and even catalyze the development of high-frequency trading. More Secure: There are fewer interactive processes in the contract, at least structurally to avoid the problems ERC20 caused due to the different permissions, which leads to complicated interactions and lengthens the operation chain and increases loopholes. Easier to Use: Various multi-native tokens can be used to pay gas fees during transactions, and thus no need to use designated tokens to pay gas fees. Easier Combination: It can support the combination of a wide range of contracts, including the combination of different consensus in the same chain, ledger structure, and other elements, and even cross chains, making DeFi a real “Lego”.
Multi-chain heterogeneous + DeFi, one unhindered currency is helping to reach the perfect
Multi-chain heterogeneity has formed “cities” and “villages”, and DeFi has become the financial center among the cities. Since we use cities for comparison, how can we avoid each city’s independent governance and link up the chains of urban interests to form a greater network? The answer is the same as in real life, that is, the so-called currency everywhere. Ethereum also provides currency, but this currency is not only inefficient, but also indirectly causes security risks. If you want long-term development, such a design is unreasonable. In the QuarkChain mainnet, multi-native tokens are our primary function for building the next generation of DeFi. Multi-native tokens have basically the same status as QKC in the QuarkChain system. They can call contracts, perform cross-chain operations, and pay gas fees under certain conditions. Native tokens can achieve all of QKC’s functions, including cross-chain transactions, except participating in QKC governance. Most of the non-native asset inconvenience problems faced by Defi can be solved. In the future contracts, the functions of native tokens will be exactly the same as QKC, with the last barrier to the application of multi-native tokens being removed. This also avoids the problem of reducing the security of the entire DeFi system due to the ERC20 token’s authority issue. Next, we will launch our DEX, and then users will have the true feeling of the unimpeded DeFi platform on QuarkChain. Thus, the last piece of the puzzle of multi-chain heterogeneous + DeFi + multi-native tokens has been fulfilled, which brings cost efficiency, user easiness, and security to a new level. Ethereum’s performance and contract security restrictions have affected development. After our repeated introduction and numerous testing, the multi-native token function is ready to be officially delivered to the community. Soon, community members can mint their own tokens and use them to transfer funds (including cross-sharding), pay gas fees, directly call smart contracts, etc. In conjunction with the DEX that we will launch in the next step, users can actually experience the convenience and innovation brought by multi-native tokens to the blockchain system. To verify the validity of this theory, we recently launched the Game of DeFi Campaign. In the last stage of the campaign, we launched a simple DEX application and a game: QSwap — the multi-native token version of Uniswap, and Element Miner — a fun mining trading game. This is the new value that DEX and game-based mining will be able to bring to DApp and DeFi applications based on the verification of multi-native tokens with the game format. Because the gas fee is low enough, every step of the operation will be on the chain to ensure security. Meantime, instead of ETH’s high gas fee, which made users either high-cost and low-efficiency, or low-cost and low-security, the multi-native token proves the real security and convenience. Our Game of DeFi Campaign has already entered the final stage. There are still millions of QKC reward pools waiting for the users to share. Users can download QPocket wallet to participate in this event.
Phase III: King’s Landing — Dex and Liquidity Mining
In this phase, all the community members can have the experience to use our two new products:
QSwap: Multi-native token version Uniswap
Unlike Uniswap, which can only support ERC20 tokens, QSwap supports multi-native tokens. Thus, no extra pre-authorized approval is required in the process, and any multi-native token can be used to pay gas fee ( not only QKC ). Users will get a better experience and maintain more security by avoiding granting unlimited authorization. Moreover, there will be a much lower gas fee due to sharding technology provided by QuarkChain infrastructure.
Element Miner: Interesting mining and trading DApp game
The player’s goal is to collect 5 elements to join the reward pool. However, since these elements are reinforcing to each other (just like the mining throughputs from different projects are different), using QSwap will be the most efficient approach. One last question: This DeFi campaign uses test tokens. What if the network uses tokens with real value?

Bithumb Global Officially Launched "Mining Coin Optimization Plan"
https://preview.redd.it/ok4pgo2jsl651.png?width=1024&format=png&auto=webp&s=b47ae7df4c842efe272144644db8fc60411a06d3 With the continuous popularization of the value of Bitcoin, the concept of digital mining has been recognized by the public, and more and more digital currencies based on "mining" have been transformed from the concept of geeks to the industrial economy, becoming the investment objects favored by investors. In order to meet the investment needs of users as much as possible, Bithumb Global officially launched the "Mining Coin Optimization Plan" to build a mining coin trading cluster. Specific measures are as follows:
Open the Mining Coin section, creating a unique function for the Mining Coin project.
Open the channel for mining coins to facilitate miners, communities and developers to submit applications for coins.
Provide media and promotion resources for high quality mining coins.
Connect mining coins community to top mining pool resources.
Provide multi-language community support to provide an international platform for high-quality mining coin projects.
In order to ensure the interests of Bithumb Global users and select projects with development potential, the basic requirements for participating in the "Mining Coin Optimization Plan" are as follows: 1) The project's code and algorithms have undergone rigorous security audits and have been approved by third parties (e.g., MIT License). 2) The project has no pre-excavation and the code is open source, so any miner can participate in the mining competition fairly. 3) Physical equipment must be involved in the mining process, i.e. new consensus mechanism supporting POW, POC and other physical equipment to participate in the mining process. 4) In the case of wallet stability, give priority to support the practice of new encryption algorithm and encourage innovative mining coins.

This article will cover both, so stay where are you are and learn about what separates ChainX from other Polkadot Parachains. ChainX is one of the several Parachains of Polkadot, a Web3 Foundation project focused on bringing the numerous blockchains of the sector together through interoperability and easy integration. The ChainX team is building a public blockchain ecosystem of multi-currency integration. With a unique PoS consensus algorithm that follows an asset mining model, “One Asset One Vote” measures mining power based on market value of large caps like BTC, ETH, EOS, and other assets from users inter-chain deposits. Deposit data is then used with Bitcoin’s model to halve output eventually, and distribute PCX tokens in the fairest way possible. If you are ready to start asset mining across different chains with ChainX, read on!
Tutorial: how to deploy your ChainX node on Ankr
Head to app.ankr.com, create an account if you don’t have one already, then click the Deploy a Node button.
Now you are taken to the configuration page. The hardware configuration is already set to the optimal system requirements, but you are allowed to increase the specifications if you wish to do so by using the Advanced button.
The platform also recommends a cluster, which is usually the one that has the most freely available resources. In this particular case, the recommended cluster is the UK cluster, but another cluster may be recommended depending on where resources are most available at the time.
If you are deploying a Full node, select if you need archiving. In case you want to query historical data, please select Archive. If this is not the case, you can go with the Non-Archive option for less disk space and faster performance.
Ethereum 2.0 Ethereum 2.0 (Eth2) is the next phase in the evolution and improvement of the public Ethereum network. With a shift from a Proof of Work to Proof of Stake consensus algorithm, Ethereum 2.0 will result in improved scalability, security, and usability for the network. Eth2 will go live in multiple phases, beginning with Phase 0 in 2020. Proof of Work Proof of Work (PoW) is a class of consensus algorithm that rewards miners who expend computational energy to solve mathematical problems to propose new blocks. With PoW, the probability of mining a block and thus receiving block rewards is a function of how much computational energy (known as hash power) a miner expends. Popular blockchains such as Bitcoin, Ethereum (1.0), and Litecoin are all Proof of Work blockchains. Proof of Stake Proof of Stake (PoS) is a class of consensus algorithm that selects and rewards validators as a function of a validator’s economic stake in the network. Unlike PoW, the probability of creating a block in a PoS network is not a result of hash power from burning energy, but rather the result of economic value-at-loss. Proof of Stake will be the consensus mechanism that Ethereum 2.0 uses to maintain the network. Unlike Proof of Work networks, Proof of Stake networks can achieve finality. Staking Staking replaces mining as the consensus mechanism in Proof of Stake blockchains. A stake is a fixed amount of funds that are ‘committed’ to a blockchain by a validator in order to participate in block creation and attestation. On Ethereum 2.0, validators will stake 32 ETH to the network and will be rewarded in ETH for their effort. If an ETH holder does not have 32 ETH, they may elect to use a staking pool to participate in Ethereum 2.0. Validators that break the rules of the network are subject to slashing of their stakes. Validator A validator is an actor on Ethereum 2.0 who proposes and attests new blocks on the network. In Proof of Stake, a validator stakes 32 ETH in order to participate in maintaining the network. If a validator is chosen to attest the next block, they are rewarded in ETH as a percentage of their stake. Conversely, validators who do not perform their duties––if they are offline, for example––receive penalties, or slashes, in the form of small amounts of ETH subtracted from their stakes. Phase 0 of Ethereum 2.0 Phase 0 is the first upgrade to the Ethereum blockchain, and marks the first stage of Ethereum 2.0. Phase 0 is the launch of the beacon chain. Phase 0 will exist only to implement the Proof of Stake consensus mechanism by managing the list of validators. It will not offer other blockchain features such as shard chains or execution: in short, participants won’t be able to make transactions or call smart contracts on Eth2 yet. Beacon Chain The beacon chain stores and manages the registry of validators, and will implement the Proof of Stake consensus mechanism for Ethereum 2.0. The beacon chain will go live in Phase 0. The original Ethereum 1.0 PoW chain will continue to run alongside the new Ethereum PoS chain, ensuring that there is no break in data continuity. Deposit Contract The Ethereum 2.0 deposit contract will be released before the beacon chain goes live in Phase 0. In order to register as a validator on the network, a user must generate Ethereum 2.0 keys by making a one-way deposit of ETH into the deposit contract that will be live on the Eth2 Launchpad, hosted by the Ethereum Foundation. Staking Provider Staking providers offer services––such as staking-as-a-service and/or staking pools––that stake funds and create, propose, or vote on blocks added to the blockchain on behalf of token holders. Staking providers help offload the technical burden of maintaining an online validator and/or reduce financial barriers to participation for participants. Staking-as-a-Service Staking-as-a-service tools with offload the technical efforts of running one own’s validator node by allowing an individual with 32 ETH to select which client they wish to use to remotely run a node and stake their funds. Staking Pools In order for an individual to become a “full” validator on Ethereum 2.0, they must stake 32 ETH. Should a user be unwilling or unable to stake 32 ETH, they may elect to send fewer than 32 ETH to a staking pool, which will combine the funds of others and stake on their behalf. Pool participants will receive rewards as a percentage of their contribution. Phase 1 of Ethereum 2.0 Phase 1 is the second upgrade to Ethereum 2.0, following Phase 0 in 2020. The primary improvement of Phase 1 is the integration of shard chains to improve scalability. Sharding / Shard Chains Sharding is a form of database partitioning, also known as horizontal partitioning, wherein large databases are divided into smaller, more manageable clusters to reduce data burden and improve scalability. On Ethereum 2.0, sharding will take the form of 64 chains running alongside the beacon chain, increasing overall throughput and scalability. Phase 1.5 of Ethereum 2.0 Phase 1.5 is a term being used to describe a period during the Phase 1 upgrade where the Ethereum 1.0 and Ethereum 2.0 blockchains are merged. After Phase 1.5, the Ethereum 1.0 chain will run as a shard of the Ethereum 2.0 PoS blockchain. This will be the moment when the full functionality of the Ethereum 1.0 chain – including the use of ETH – will become functional on Ethereum 2.0 without risking a break in data consistency. Phase 2 of Ethereum 2.0 Phase 2 is the third phase of Ethereum 2.0, following Phase 0 and Phase 1. This phase is currently less clearly defined than the preceding two phases, but it will involve adding ether accounts, enabling transfers and withdrawals, implementing cross-shard transfers and contract calls, building execution environments so that scalable applications can be built on top of Ethereum 2.0, and bringing the Ethereum 1.0 chain into Ethereum 2.0 so that Proof of Work can finally be turned off. Finality Proof of Stake blockchains can offer finality. After a small period of time, a block is declared final, which means that it can never be changed. All the transactions in that block and all previous transactions are permanent, immutable, and guaranteed forever. Proof of Work chains offer much weaker guarantees around finality. Slashing Ethereum 2.0’s consensus mechanism has a couple of rules that are designed to prevent attacks on the network. Any validator found to have broken these rules will be slashed and ejected from the network. Slashing means that a significant part of the validator’s stake is removed: up to the whole stake of 32 ETH in the worst case. Validator software and staking providers will have built-in protection against getting slashed accidentally. Slashing should only affect validators who misbehave deliberately.
Problem: I am running python codes for a few million iterations and my computer can't handle the workload. It ends up crashing and and my CPU and Memory usage are through the roof. (Specs: i5-7200U CPU 2.50 GHz 2.70 GHz, 8G RAM) Solutions I am thinking: 1) Build a cluster computer from Raspberry Pis but I dont know how to calculate how many Pis (nodes) I need and if this is the best solution. 2) Build a custom computer but I am not sure what specs I need. I am aware that people in bitcoin mining use crazy FLOP rates and I thought I can use a similar product to run my programming project however, I am confused because some use CPU/GPU methods and others use strong graphic cards. I will only use the new computer system to run my programming codes i.e. no requirements for gaming, movies etc. I welcome any ideas you might have and would love some help.
