Epic Cash AMA Recap with CryptoDiffer Community

CryptoDiffer team Hello, everyone! We are glad to meet here: Max Freeman (@maxfreeman4), Project Lead at Epic Cash Yoga Dude (@Yogadude), PR&Marketing at Epic Cash Xenolink (@Xenolink), Advisor at Epic Cash
Max Freeman Project Lead at Epic Cash Thanks Max, we are excited to be here!
Yoga Dude PR&Marketing at Epic Cash Hello Everyone! Thank you for having us here!
Xenolink Advisor at Epic Cash Thank you to the CryptoDiffer team and CryptoDiffer community for hosting us!
CryptoDiffer team Let`s start from the first introduction question: Q1: Can you introduce yourself to the community? What is your background and how did you join Epic Cash?
Yoga Dude PR&Marketing at Epic Cash
Hello! My background is Marketing and Business Development, I’ve been in crypto since 2011 started with Bitcoin, then Monero in 2014, Ethereum in 2015 and at some point Doge for fun and profit. I joined Epic Cash team in September 2019 handling PR and Marketing.
I saw in Epic Cash what was missing in my previous cryptos — things that were missing in Bitcoin and Monero especially.
Xenolink Advisor at Epic Cash
Hello Cryptodiffer Community, I am not an original co-founder nor am I a developer for the Epic Cash project. I am however a community member that is involved in helping scale this project to higher levels. One of the many beauties of Epic Cash is that every single member in the community has the opportunity to be part of EPIC’s team, it can be from development all the way to content producing. Epic Cash is a community driven project. The true Core Team of Epic Cash is our community. I believe a community that is the Core Team is truly powerful. EPIC Cash has one of the freshest and strongest communities I have seen in quite a while. Which is one of the reasons why I became involved in this project. Epic displayed some of the most self community produced content I have seen in a project. I’m actually a doctor of medicine but in terms of my experience in crypto, I have been involved in the industry since 2012 beginning with mining Litecoin. Since then I have been doing deep dive analysis on different projects, investing, and building a network in crypto that I will utilize to help connect and scale Epic in every way I can. To give some credit to those people in my network that have been a part of helping give Epic exposure, I would like to give a special thanks to u/Tetsugan and u/Saurabhblr. Tetsugan has been doing a lot of work for the Japanese community to penetrate the Japanese market, and Japan has already developed a growing interest in Epic. Daku Sarabh the owner and creator of Crypto Daku Robinhooders, I would like to thank him and his community for giving us one of our first large AMA’s, which he has supported our project early and given us a free AMA. Many more to thank but can’t be disclosed. Also thank you to all the Epic Community leaders, developers, and Content producers!
Max Freeman Project Lead at Epic Cash
I’m Max Freeman, which stands for “Maximum Freedom for Mankind”. I started working on the ideas that would become Epic in 2018. I fell in love with Bitcoin in 2017 but realized that it needs privacy at the base layer, fungibility, better scalability in order to go to the next level.
CryptoDiffer team
Really interesting backgrounds I must admit, pleasure to see the team that clearly has one vision of the project by being completely decentralized:)
Q2: Can you briefly describe what is Epic Cash in 3–5 sentences? What technology stands behind Epic Cash and why it’s better than the existing one?
Max Freeman Project Lead at Epic Cash
I’d like to highlight the differences between Epic and the two highest-valued privacy coin projects, Monero and Zcash. XMR has always-on privacy like Epic does, but at a cost: Its blockchain is over 20x more data intensive than Epic, which limits its possibilities for scalability. Epic’s blockchain is small and light enough to run a full node on cell phones, something that is in our product road map. ZEC by comparison can’t run on low end devices because of its zero knowledge based approach, and only 1% of transactions are fully private. Epic is simply newer, more advanced technology than prior networks thanks to Mimblewimble
We will also add more algorithms to widen the range of hardware that can participate in mining. For example, cell phones and tablets based around ARM chips. Millions of people can mine Epic that can’t mine Bitcoin, and that will help grow the network rapidly.
There are some great short videos on our YouTube channel https://www.youtube.com/channel/UCQBFfksJlM97rgrplLRwNUg/videos
that explain why we believe we have created something truly special here.
Our core architecture derives from Grin, so we are fortunate to benefit on an ongoing basis from their considerable development efforts. We are focused on making our currency truly usable and widely available, beyond a store of value and becoming a true medium of exchange.
Yoga Dude PR&Marketing at Epic Cash
Well we all have our views, but in a nutshell, we offer things that were missing in the previous cryptos. We have sound fiscal emission schedule matching Bitcoin, but we are vastly more private and faster. Our blockchain is lighter than Bitcoin or Monero and our tech is more scalable. Also, we are unique in that we are mineable with CPUs and GPUs as well as ASICs, giving the broadest population the ability to mine Epic Cash. Plus, you can’t forget FUNGIBILITY 🙂 we are big on that — since you can’t have true privacy without fungibility.
Also, please understand, we have HUGE respect to all the cryptos that came before us, we learned a lot from them, and thanks to their mistakes we evolved.
Xenolink Advisor at Epic Cash
To add on, what also makes Epic Cash unique is the ability to decentralize the mining using a tri-algo model of Random X (CPU), Progpow (GPU), and Cuckoo (ASIC) for an ability to do hybrid mining. I believe this is an issue we can see today in Bitcoin having centralized mining and the average user has a costly barrier of entry.
To follow up on this one in my opinion one of the things we adopted that we have seen success for , in example Bitcoin and Monero, is a strong community driven coin. I believe having a community driven coin will provide a more organic atmosphere especially when starting with No ICO, or Premine with a fair distribution model for everyone.
CryptoDiffer team
Q3: What are the major milestones Epic Cash has achieved so far? Maybe you can share with us some exciting plans for future weeks/months?
Yoga Dude PR&Marketing at Epic Cash
Since we went live in September of 2019, we attracted a very large community of users, miners, investors and contributors from across the world. Epic Cash is a very international project with white papers translated into over 30 languages. We are very much a community driven project; this is very evident from our content and the amount of translations in our white papers and in our social media content.
We are constantly working on improving our usability, security and privacy, as well as getting our message and philosophy out into the world to achieve mass adoption. We have a lot of exciting plans for our project, the plan is to make Epic Cash into something that is More than Money.
You can tell I am the Marketing guy since my message is less about the actual tech and more about the usability and use cases for Epic Cash, I think our Team and Community have a great mix of technical, practical, social and fiscal experiences. Since we opened our YouTube channels content for community submissions, we have seen our content translated into Spanish, French, German, Polish, Chinese, Japanese, Arabic, Russian, and other languages
Max Freeman Project Lead at Epic Cash
Our future development roadmap will be published soon and includes 4 tracks:
Usability
Mining
Core Protocol
Ecosystem Development
Core Protocol
Epic Server 2.9.0 — this release improves the difficulty adjustment and is aimed at making block emission closer to the target 60 seconds, particularly reducing the incidence of extremely short and long blocks — Status: In Development (Testing) Anticipated Release: June 2020
Epic Server 3.0.0 — this completes the rebase to Grin 3.0.0 and serves as the prerequisite to some important functional building blocks for the future of the ecosystem. Specifically, sending via Tor (which eliminates the need to open ports), proof of payment (useful for certain dex applications e.g. Bisq), and our native mobile app. Status: In Development (Testing) Anticipated Release: Fall 2020
Non-Interactive Transactions — this will enhance usability by enabling “fire and forget” send-to-address functionality that users are accustomed to from most cryptocurrencies. Status: Drawing Board Anticipated Release: n/a
Scaling Options — when blocks start becoming full, how will we increase capacity? Two obvious options are increasing the block size, as well as a Lightning Network-style Layer 2 structure. Status: Drawing Board Anticipated Release: n/a
Confidential Assets — Similar to Raven, Tari, and Beam, the ability to create independently tradable assets that ride on the Epic Blockchain. Status: Drawing Board Anticipated Release: n/a
Usability
GUI Wallet 2.0 — Restore from seed words and various usability enhancements — Status: Needs Assessment Anticipated Release: Fall 2020
Mobile App — Native mobile experience for iOS and Android. Status: In Development (Testing) Anticipated Release: Winter 2020
Telegram Integration — Anonymous payments over the Telegram network, bot functionality for groups. Status: Drawing Board Anticipated Release: n/a
Mining
RandomX on ARM — Our 4th PoW algorithm, this will enable tablets, cell phones, and low power devices such as Raspberry Pi to participate in mining. Status: Needs Assessment Anticipated Release: n/a
The economics of mining Epic are extremely compelling for countries that have free or extremely cheap electricity, since anyone with an ordinary PC can mine. Individual people around the world can simply run the miner and earn meaningful money (imagine Venezuela for example), something that has not been possible since the very early days of Bitcoin.
Ecosystem Development
Atomic Swaps — Connecting Epic to other blockchains in a trustless way, starting with ETH so that Epic can trade on DeFi infrastructure such as Uniswap, Kyber, etc. Status: Drawing Board Anticipated Release: n/a
Xenolink Advisor at Epic Cash
From the Community aspect, we have been further developing our community international reach. We have been seeing an increase in interest from South America, China, Russia, Japan, Italy, and the Philippines. We are working on targeting more countries. We truly aim to be a decentralized project that is open to everyone worldwide.
CryptoDiffer team
Great, thank you for your answers, we now can move to community questions part!
Cryptodiffer Community
You have 3 mining algorithms, the question is: how do they not compete with each other? Is there any benefit of mining on the GPU and CPU if someone is mining on the ASIC?
Max Freeman Project Lead at Epic Cash
The block selection is deterministic, so that every 100 blocks, 60% are for RandomX (CPU), 38% for ProgPow (GPU), and 2% for Cuckoo (ASIC) — the policy is flexible so that we can have as many algorithms with any percentages we want. The goal is to make the most decentralized and resilient network possible, and with that in mind we are excited to work on enabling tablets and cell phones to mine, since that opens it up to millions of people that otherwise can’t take part.
Cryptodiffer Community
To Run a project smoothly, Funding is very important, From where does the Funding/revenue come from?
Xenolink Advisor at Epic Cash
Yes, early on this was realized and in order to scale a project funds are indeed needed. Epic Cash did not start with any funding and no ICO and was organically genesis mined with no pre-mine. Epic cash is also a nonprofit community driven project similar to Monero. There is no profit-driven entity in the picture. To overcome the revenue issue Epic Cash setup a development fund tax that decreases 1% every year until 2028 when Epic Cash reaches singularity with Bitcoin emissions. Currently it is at 7.77%. This will help support the scaling of the project.
Cryptodiffer Community
Hi! In your experience working also with MONERO can you please clarify which are those identified problems that EPIC CASH aims to develop and resolve? What’s the main advantage that EPIC CASH has over MONERO? Thank you!
Yoga Dude PR&Marketing at Epic Cash
First, I must admit that I am still a huge fan and HODLer of Monero. That said:
✅ our blockchain is MUCH lighter than Monero’s
✅ our transaction processing speed is much faster
✅ our address-less blockchain is more private
✅ Epic Cash can be mined with CPU (RandomX) GPU (ProgPow) and Cuckoo, whereas Monero migrated to RandomX and currently only mineable with CPU

  1. the feature ‘Cut Through’ deletes old data, how is it decided which data will be deletes, and what are the consequences of it for the platform and therefore the users?
  2. On your website I see links to download Epic wallet and mining software for Linux,Windows and MacOs, I am a user of android, is there a version for me, or does it have a release date?
Max Freeman Project Lead at Epic Cash
  1. This is one of the most exciting features of Mimblewimble, which is its extraordinary ability to compress blockchain data. In Bitcoin, the entire history of a coin must be replayed every time it is spent, and comprehensive details are permanently stored in the blockchain. Epic discards spent transaction inputs and consolidates outputs, storing neither addresses or amounts, only a tiny kernel to allow sender and receiver to prove their transaction.
  2. The Vitex mobile app is great for today, and we have a native mobile app for iOS and Android in the works as well.

$EPIC Have total Supply of 21,000,000 EPIC , is there any burning plan? Or Buyback program to maintain $EPIC price in the future?
Who is Epic Biggest competitors?
And what’s makes epic better than competitors?
Xenolink Advisor at Epic Cash
We respect the older generation coins like Bitcoin. But we have learned that the supply economics of Bitcoin is very sound. Until today we can witness how the Bitcoin is being adopted institutionally and by retail. We match the 21 million BTC supply economics because it is an inelastic fixed model which makes the long-term economics very sound. To have an elastic model of burning tokens or printing tokens will not have a solid economic future. Take for example the USD which is an inflating supply. In terms of competitors we look at everyone in crypto with respect and also learn from everyone. If we had to compare to other Mimblewimble tech coins, Grin is an inelastic forever inflating supply which in the long term is not sound economics. Beam however is an inelastic model but is formed as a corporation. The fair distribution is not there because of the permanent revenue model setup for them. Epic Cash a non-profit development tax fund model for scaling purposes that will disappear by 2028’s singularity.
Cryptodiffer Community
What your plans in place for global expansion, are you focusing on only market at this time? Or focus on building and developing or getting customers and users, or partnerships?
Yoga Dude PR&Marketing at Epic Cash
Since we are a community project, we have many developers, in addition to the core team.
Our plans for Global expansion are simple — we have advocates in different regions addressing their audiences in their native languages. We are growing organically, by explaining our ideology and usability. The idea is to grow beyond needing a fiat bridge for crypto use, but to rather replace fiat with our borderless, private and fungible crypto so people can use it to get goods and services without using banks.
We are not limiting ourselves to one particular demographic — Epic Cash is a valid solution for the gamers, investors, techie and non techie people, and the unbanked.
Cryptodiffer Community
EPIC confidential coin! Did you have any problems with the regulators? And there will be no problems with listing on centralized exchanges?
Xenolink Advisor at Epic Cash
In terms of structure, we are carefully set up to minimize these concerns. Without a company or investors in the picture, and having raised no funds, there is little scope to attack in terms of securities laws. Bitcoin and Ethereum are widely acknowledged as acceptable, and we follow in their well-established footprints in that respect. Centralized exchanges already trade other privacy coins, so we don’t see this as much of an issue either. In general, decentralized p2p exchange options are more interesting than today’s centralized platforms. They are more censorship resistant, secure, and privacy-protecting. As the technology gets better, they should continue to gain market share and that’s why we’re proud to be partnered with Vitex, whose exchange and mobile app work very well.

What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Max Freeman Project Lead at Epic Cash
Because our blockchain is so light (only 1.16gb currently, and grows very slowly) it is naturally well suited to become a decentralized mobile money standard because people can run a full node on their phone, guaranteeing the security of their funds. Scalability in Bitcoin requires complicated and compromised workarounds such as Lightning Network and light clients, and these problems are solved in Epic.
With our forthcoming Mobile Mining app, hundreds of millions of cell phones and tablets will be able to easily join the network. People can quickly and cheaply send money to one another, fulfilling the long-envisioned promise of P2P electronic cash.
As an investor, it’s important to ask a few key questions. Bitcoin Standard tokenomics of disinflation and a fixed supply are well proven over a decade now. We follow this model exactly, with a permanently synchronized supply from 2028, and 4 emission halvings from now until then, with our first one in about two weeks. Beyond that, we can apply some simple logical tests. What is more valuable, money that can only be used in some cases (censorable Bitcoin based on a lack of fungibility) or money that can be used universally? (fungible Epic based on always-on privacy by default). Epic is also poised to be a more decentralized and therefore resilient network because of wider participation in mining. Epic is designed to be Bitcoin++ Privacy, Fungibility, Scalability
Cryptodiffer Community
Q1. What are advantages for choosing three mining algorithms RandomX+, ProgPow and CuckAToo31+ ?
Q2. Beam and Grin use MimbleWimble protocol, so what are difference for Epic? All of you will be friends for partners or competitors?
Max Freeman Project Lead at Epic Cash
RandomX and ProgPow are designed to use the entirety of a CPU / GPU’s unique processing capabilities in a way that other types of hardware don’t work as well. You can run RandomX on a GPU but it doesn’t work nearly as well as a much cheaper CPU, for example. Cuckoo is a “memory hard” algorithm that widens the range of companies that can produce the hardware.
Grin and Beam are great projects and we’ve learned a lot from them. We inherited our first codebase from Grin’s excellent Rust design, which is a better language for community participation than C++ that Beam currently uses.
Functionally, Mimblewimble is similar across the 3 coins, with standard Confidential Transactions, CoinJoin, Dandelion++, Schnorr Signatures and other advanced features. Grin is primarily ASIC-targeted, Beam is GPU-targeted, and Epic is multi-hardware.
The biggest differences though are in tokenomics and project structure. Grin has permanent inflation of 60 coins per block with no halvings, which means steady erosion of value over time due to new supply pressure. It also lacks a steady funding model, making future development in jeopardy, particularly as the per coin price falls. Beam has a for-profit model with heavy early inflation and a high developer tax. Epic builds on the strengths of these earlier mimblewimble projects and addresses the parts that could be improved.
Cryptodiffer Community Some privacy coin has scalability issues! How Epic cash will solve scalability issues? Why you choose randomX consensus algorithem?
Xenolink Advisor at Epic Cash
Fungibility means that you can’t distinguish one unit of currency from another, in example Gold. Fungibility has recently become a hot issue as people have been noticing Bitcoins being locked up by exchanges which may of had a nefarious history which are called Tainted Coins. In example coins that have been involved in a hack, darknet market transactions, or even processing coin through a mixer. Today we can already see freshly mined Bitcoins being sold at a premium price to avoid the fungibility problem Bitcoin carries today. Bitcoin can be tracked by chainalysis and is not a fungible cryptocurrency. One of the features that Epic has is privacy with added fungibility, because of Mimblewimble technology, Epic has no addresses recorded and therefore nothing can be tracked by chainalysis. Below I provide a link of an example of what the lack of fungibility is resulting in today with Bitcoin. One of the reasons why we chose the Random X algo. is because of the easy barrier of entry and also to further decentralize the mining. Random X algo can be mined on old computers or laptops. We also have 2 other algos Progpow (GPU), and Cuckoo (ASIC) to create a wider decentralization of mining methods for Epic.
Cryptodiffer Community
I’m a newbie in crypto and blockchain so how will Epic Cash team target and educate people who don’t know about blockchain and crypto?
What is the uniqueness of Epic Cash that cannot be found in other project that´s been released so far ?
Yoga Dude Pr&Marketing at Epic Cash
Actually, while we have our white paper translated into over 30 languages, we are more focused on explaining our uses and advantages rather than cold specs. Our tech is solid, but we not get hung up on pure tech talk which most casual users do not need to or care to understand. As long as our fundamentals and tech are secure and user friendly our primary goal is to educate about use cases and market potential.
The uniqueness of Epic Cash is its amalgamation of “whats good” in other cryptos. We use Mimblewimble for privacy and anonymity. Our blockchain is much lighter than our competitors. We are the only Mimblewimble crypto to use a unique cocktail of mining algorithms allowing to be mined by casual miners with gaming rigs and laptops, while remaining friendly to GPU and CPU farmers.
The “uniqueness” is learning from the mistakes of those who came before us, we evolved and learned, which is why our privacy is better, we are faster, we are fungible, we offer diverse mining and so on. We are the best blend — thats powerful and unique
Cryptodiffer Community
Can you share EPIC’s vision for decentralized finance (DEFI)? What features do EPIC have to support DEFI?
Yoga Dude PR&Marketing at Epic Cash
We view Epic as ideally suited to be the decentralized digital reserve asset of the new Private Internet of Money that’s emerging. At a technology level, atomic swaps can be created to build liquidity bridges so that wrapped Epic tokens (like WBTC, WETH) can trade on other networks as ERC20, BEP2, NEP5, VIP180, Algorand and so on. There is more Bitcoin value locked on Ethereum than in Lightning Network, so we will similarly integrate Epic so that it can trade on networks such as Uniswap, Kyber, and so on.
Longer term, if there is market demand for it, thanks to Scriptless Script functionality our blockchain has, we can build “Confidential Assets” (which Raven, Tari, and Beam are all also working on) that enable people to create tokenized assets in a private way.
Cryptodiffer Community
If you could choose one celebrity to promote Epic-cash, who that would be?
Max Freeman Project Lead at Epic Cash
I am a firm believer that the strength of the project lies in allowing community members to become their own celebrities, if their content is good enough the community will propel them to celebrity status. Organic celebrities with small but loyal following are vastly more beneficial than big name professional shills with inflated but non caring audiences.
I remember the early days of Apple when an enthusiastic dude named Guy Kawasaki became Apple Evangelist, he was literally going around stores that sold Apple and visited user groups and Evangelized his belief in Apple. This guy became a Legend and helped Apple become what it is today.
Epic Cash will have its OWN Celebrities
Cryptodiffer Community
How does $EPIC solve scalability of transactions? Current blockchains face issues with scalability a lot, how does $EPIC creates a solution to it?
Xenolink Advisor at Epic Cash
Epic Cash is utilizing Mimblewimble technology. Besides the privacy & fungibility aspect of the tech. There is the scalability features of it. It is implemented into Epic by transaction cut-through. Which means it allows nodes to remove all intermediate transactions, thus significantly reducing the blockchain size without affecting its validation. Mimblewimble also does not use addresses like a BTC address, and amount of transactions are also not recorded. One problem Monero and Bitcoin are facing now is scalability. It is evident today that data is getting more expensive and that will be a problem in the long run for those coins. Epic is 90% lighter and more scalable compared to Monero and Bitcoin.
Cryptodiffer Community
what are the ways that Epic Cash generates profits/revenue to maintain your project and what is its revenue model ? How can it make benefit win-win to both invester and your project ?
Max Freeman Project Lead at Epic Cash
There is a block subsidy of 7.77% that declines 1.11% per year until 0, where it stays after that. As a nonprofit community effort, this extremely modest amount goes much further than in other projects, which often take 20, 30, even 50+ % of the coin supply. We believe that this ongoing funding model best aligns the long term incentives for all participants and balances the compromises between the ends of the centralized/decentralized spectrum of choices that any project must make.
Cryptodiffer Community
Q1 : What are your major goals to archive in the next 3–4 years?
Q2 : What are your plans to expand and gain more adoption?
Yoga Dude Pr&Marketing at Epic Cash
Max already talked about our technical plans and goals in his roadmap. Allow me to talk more about the non technical 😁
We are aiming for broader reach in the non technical more mainstream community — this is a big challenge but we believe it is doable. By offering simpler ways to mine Epic Cash (with smart phones for example), and by doing more education we will achieve the holy grail of crypto — moving past the fiat bridges and getting Epic Cash to be accepted as means of payment for goods and services. We will accomplish this by working with regional advocacy groups, community interaction, off-line promotional activities and diverse social media targeting.
Cryptodiffer Community
It seems to me that EpicCash will have its first Halving, right? Why a halving so soon?
Is a mobile version feasible?
Max Freeman Project Lead at Epic Cash
Our supply emission catches up to that of Bitcoin’s first 19 years after 8 years in Epic, so that requires more frequent halvings. Today’s block emission is 16, next up are 8, 4, 2, and then finally 0.15625. After that, the supply of Epic and that of BTC stay synchronized until maxing out at 21m coins in 2140.
Today we have a mobile wallet through the Vitex app, a native mobile wallet coming, and are working on mobile mining.
Cryptodiffer Community
What markets will you add after that?
Yoga Dude PR&Marketing at Epic Cash
Well, we are aiming to have ALL markets
Epic Cash in its final iteration will be usable by everyone everywhere regardless of their technical expertise. We are not limiting ourselves to the technocrats, one of our main goals is to help the billions of unbanked. We want everyone to be able to mine, buy, and most of all USE Epic Cash — gamers, farmers, soccer moms, students, retirees, everyone really — even bankers (well once we defeat the banking industry)
We will continue building on the multilingual diversity of our global community adding support and advocacy groups in more countries in more languages.
Epic Cash is More than Money and its for Everyone.
Cryptodiffer Community
Almost, all cryptocurrencies are decentralized & no-one knows who owns that cryptocurrencies ! then also, why Privacy is needed? hats the advantages of Private coins?
Max Freeman Project Lead at Epic Cash
With a public transparent blockchain such as Bitcoin, you are permanently posting a detailed history of your money movements open for anyone to see (not just legitimate authorities, either!) — It would be considered crazy to post your credit card or bank statements to Twitter, but that’s what is happening every time you send a transaction that is not private. This excellent video from community contributor Spencer Lambert https://www.youtube.com/watch?v=0blbfmvCq\_4 explains better than I can.
Privacy is not just for criminals, it’s for everyone. Do you want your landlord to increase the rent when he sees that you get a raise? Your insurance company to raise your healthcare costs because they see you buying too much ice cream? If you’re a business, do you want your employees to see how much money their coworkers make? Do you want your competitors to trace your supplier and customer relationships? Of course not. By privacy being default for everyone, cryptocurrency can be used in a much wider range of situations without unacceptable compromises.
Cryptodiffer Community
What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Xenolink Advisor at Epic Cash
Epic Cash can be used as a Private and Fungible store of value, medium of exchange, and unit of account. As Epic Cash grows and becomes adopted it can be compared to how Bitcoin and Monero is used and adopted as well. As Epic is adopted by the masses, it can be accepted as a medium of exchange for store owners and as fungible payments without the worry of having money that is tainted. Epic Cash as a store of value may be a good long term aspect of investment to consider. Epic Cash carries an inelastic fixed supply economic model of 21 million coins. There will be 5 halvings which this month of June will be our first halving of epic. From a block reward of 16 Epic reduced to 8. If we look at BTC’s price action and history of their halvings it has been proven and show that there has been an increase in value due to the scarcity and from halvings a reduction of # of BTC’s mined per block. An inelastic supply model like Bitcoin provides proof of the circulating supply compared to the total supply by the history of it’s Price action which is evident in long term charts since the birth of Bitcoin. EPIC Plans to have 5 halvings before the year 2028 to match the emissions of Bitcoin which we call the singularity event. Below is a chart displaying our halvings model approaching singularity. Once bitcoin and cryptocurrency becomes adopted mainstream, the fungibility problem will be more noticed by the general public. Privacy coins and the features of fungibility/scalability will most likely be sought over. Right now a majority of people believe that all cryptocurrency is fungible. However, that is not true. We can already see Chainalysis confirming that they can trace and track and even for other well-known privacy coins today such as Z-Cash.

  1. You aim to reach support from a global community, what are your plans to get spanish speakers involved into Epic Cash? And emerging markets like the african
  2. How am I secure I won’t be affected by receiving tainted money?
Max Freeman Project Lead at Epic Cash
Native speakers from our community are working to raise awareness in key markets such as mining in Argentina and Venezuela for Spanish (Roberto Navarro called Epic “the holy grail of cryptocurrency” and Ethiopia and certain North African countries that have the lowest electricity costs in the world. Remittances between USA and Latin American countries are expensive and slow, so Epic is also perfect for people to send money back home as well.
Cryptodiffer Community
Do EPICs in 2020 focus more on research and coding, or on sales and implementation?
Yoga Dude PR&Marketing at Epic Cash
We will definitely continue to work on research and coding, with emphasis on improved accessibility (especially via smartphones) usability, security and privacy.
In terms of financial infrastructure will continuing to add exchanges both KYC and non KYC.
Big part of our plans is in ongoing Marketing and PR outreach. The idea is to make Epic Cash a viral sensation of sorts. If we can get Epic Cash adopters to spread the word and tell their family, coworkers and friends about Epic Cash — there will be no stopping us and to help that happen we have a growing army of content creators, and supporters.
Everyone with skin in the game gets the benefit of advancing the cause.
Folks also, this isn’t an answer to the question but an example of a real-world Epic Cash content —
https://www.youtube.com/watch?v=XtAVEqKGgqY
a challenge from one of our content creators to beat his 21 pull ups and get 100 epics! This has not been claimed yet — people need to step up 🙂 and to help that I will match another 100 Epic Cash to the first person to beat this

I was watching some videos explaining how to send and receive transactions in EpicCash, which consists of ports and sending links, my question is why this is so, which, for now, looks complex?
Let’s talk about the economic model, can EpicCash comply with the concept of value reserve?
Max Freeman Project Lead at Epic Cash
In V3, which is coming later this summer, Epic can be sent over Tor, which eliminates this issue of port opening, even though using tools like ngrok.io, it’s not necessarily as painful as directly configuring the router ports. Early Lightning Network had this issue as well and it’s something we have a plan to address via research into non-interactive transactions. “Fire and Forget” payments to an address, as people are used to in Bitcoin, is coming to Epic and we’re excited to develop functionality that other advanced mimblewimble coins don’t yet have. We are committed to constant improvement in usability and utility, to make our money system the ease of use leader.
We are involved in the project (anyone can join the Freeman Family) because we believe that simply by choosing to use a form of money that better aligns with our ideals, that we can make a positive change in the world. Some of my thoughts about how I got involved are here: https://medium.com/epic-cash/the-freeman-family-e3b9c3b3f166

Huge thanks to our friends Maks and Vladyslav, we welcome everyone to come say hi at one of our friendly communities. It is extremely early in this journey, our market cap is only 0.5m right now, whereas the 3 other mimblewimble coins are at $20m, $30m and $100m respectively. Epic is a historic opportunity to follow in the footsteps of legends such as Bitcoin and Monero, and we hope to become the first Top 5 privacy coin project.

I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

Requirements:
1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

read.cash censorship! 🤬

Well, now that I've got your attention, I want to talk with you about something serious.
Something that we've been expecting from day one opening read.cash happened. We've had to hide an article from the main page and the topic pages.
The article is (in our subjective opinion) an insulting piece of content to some people. And I, as the one who removed it, wanted to show it to you, including our whole discussion with its author.
We at read.cash want to be clear from day one that "We strive to build a place with great content to read and watch, where authors can be compensated by their readers, not the place with never-ending fights or spam" This is written in the "About" page from day one.
Unfortunately, it also means having to moderate discussions, something that some people refer to as "censorship".
We don't hide this fact. We are ok with discussions.
Want to discuss why Bitcoin SV made some bad choices and how it would never amount to anything - avoid name-calling and trash-talking and be our guest - aboslutely OK.
Do you want to criticize Bitcoin Cash because you believe that 32 MB blocks are too big and Raspberry Pis should be the miners? Be polite and you're welcome to explain yourself.
Do you want to call people "cuckolds", "bcashers" or "coretards"? Please leave, the content is going to be removed.
Anyway, we're not forcing people to love read.cash, it is, what it is. We want to make sure that authors that write great content - get compensated well by their fans.
Do you want endless flame wars? There's Twitter, and other sites that are more appropriate.
You are all grown ups and free to make your own mind about whether read.cash is suitable for you or not, we're making our policy clear.
Feel free to read this post in full and we encourage @kos (don't know the Reddit username) to join the discussion. He(she?) feels it's "haha funny article m'dude", we feel it crosses the like of being "hate-filled" (subjective term, but we stand by it).
Here's the article with discussion in full:

Best $100-$300 FPGA development board in 2018?

Hello, I’ve been trying to decide on a FPGA development board, and have only been able to find posts and Reddit threads from 4-5 years ago. So I wanted to start a new thread and ask about the best “mid-range” FGPA development board in 2018. (Price range $100-$300.)
I started with this Quora answer about FPGA boards, from 2013. The Altera DE1 sounded good. Then I looked through the Terasic DE boards.
Then I found this Reddit thread from 2014, asking about the DE1-SoC vs the Cyclone V GX Starter Kit: https://www.reddit.com/FPGA/comments/1xsk6w/cyclone_v_gx_starter_kit_vs_de1soc_board/‬ (I was also leaning towards the DE1-SoC.)
Anyway, I thought I better ask here, because there are probably some new things to be aware of in 2018.
I’m completely new to FPGAs and VHDL, but I have experience with electronics/microcontrollers/programming. My goal is to start with some basic soft-core processors. I want to get some C / Rust programs compiling and running on my own CPU designs. I also want to play around with different instruction sets, and maybe start experimenting with asynchronous circuits (e.g. clock-less CPUs)
Also I don’t know if this is possible, but I’d like to experiment with ternary computing, or work with analog signals instead of purely digital logic. EDIT: I just realized that you would call those FPAAs, i.e. “analog” instead of “gate”. Would be cool if there was a dev board that also had an FPAA, but no problem if not.
EDIT 2: I also realized why "analog signals on an FPGA" doesn't make any sense, because of how LUTs work. They emulate boolean logic with a lookup table, and the table can only store 0s and 1s. So there's no way to emulate a transistor in an intermediate state. I'll just have play around with some transistors on a breadboard.
UPDATE: I've put together a table with some of the best options:
Board Maker Chip LUTs Price SoC? Features
icoBoard Lattice iCE40-HX8K 7,680 $100 Sort of A very simple FPGA development board that plugs into a Raspberry Pi, so you have a "backup" hard-core CPU that can control networking, etc. Supports a huge range of pmod accessories. You can write a program/circuit so that the Raspberry Pi CPU and the FPGA work together, similar to a SoC. Proprietary bitstream is fully reverse engineered and supported by Project IceStorm, and there is an open-source toolchain that can compile your hardware design to bitstream. Has everything you need to start experimenting with FPGAs.
iCE40-HX8K Breakout Board Lattice iCE40-HX8K-CT256 7,680 $49 No 8 LEDs, 8 switches. Very similar to icoBoard, but no Raspberry Pi or pmod accessories.
iCE40 UltraPlus Lattice iCE40 UltraPlus FPGA 5280 $99 No Chip specs. 4 switchable FPGAs, and a rechargeable battery. Bluetooth module, LCD Display (240 x 240 RGB), RGB LED, microphones, audio output, compass, pressure, gyro, accelerometer.
Go Board Lattice ICE40 HX1K FPGA 1280 $65 No 4 LEDs, 4 buttons, Dual 7-Segment LED Display, VGA, 25 MHz on-board clock, 1 Mb Flash.
snickerdoodle Xilinx Zynq 7010 28K $95 Yes Xilinx Zynq 7-Series SoC - ARM Cortex-A9 processor, and Artix-7 FPGA. 125 IO pins. 1GB DDR2 RAM. Texas Instruments WiLink 8 wireless module for 802.11n Wi-Fi and Bluetooth 4.1. No LEDs or buttons, but easy to wire up your own on a breadboard. If you want to use a baseboard, you'll need a snickerdoodle black ($195) with the pins in the "down" orientation. (E.g. The "breakyBreaky breakout board" ($49) or piSmasher SBC ($195)). The snickerdoodle one only comes with pins in the "up" orientation and doesn't support any baseboards. But you can still plug the jumpers into the pins and wire up things on a breadboard.
numato Mimas A7 Xilinx Artix 7 52K $149 No 2Gb DDR3 RAM. Gigabit Ethernet. HDMI IN/OUT. 100MHz LVDS oscillator. 80 IOs. 7-segment display, LEDs, buttons. (Found in this Reddit thread.)
Ultra96 Xilinx Zynq UltraScale+ ZU3EG 154K $249 Yes Has one of the latest Xilinx SoCs. 2 GB (512M x32) LPDDR4 Memory. Wi-Fi / Bluetooth. Mini DisplayPort. 1x USB 3.0 type Micro-B, 2x USB 3.0 Type A. Audio I/O. Four user-controllable LEDs. No buttons and limited LEDs, but easy to wire up your own on a breadboard
Nexys A7-100T Xilinx Artix 7 15,850 $265 No . 128MiB DDR2 RAM. Ethernet port, PWM audio output, accelerometer, PDM microphone, microphone, etc. 16 switches, 16 LEDs. 7 segment displays. USB HID Host for mice, keyboards and memory sticks.
Zybo Z7-10 Xilinx Zynq 7010 17,600 $199 Yes Xilinx Zynq 7000 SoC (ARM Cortex-A9, 7-series FPGA.) 1 GB DDR3 RAM. A few switches, push buttons, and LEDs. USB and Ethernet. Audio in/out ports. HDMI source + sink with CEC. 8 Total Processor I/O, 40 Total FPGA I/O. Also a faster version for $299 (Zybo Z7-20).
Arty A7 Xilinx Artix 7 15K $119 No 256MB DDR3L. 10/100 Mbps Ethernet. A few switches, buttons, LEDs.
DE10-Standard (specs) Altera Cyclone V 110K $350 Yes Dual-core Cortex-A9 processor. Lots of buttons, LEDs, and other peripherals.
DE10-Nano Altera Cyclone V 110K $130 Yes Same as DE10-Standard, but not as many peripherals, buttons, LEDs, etc.

Winner:

icoBoard ($100). (Buy it here.)
The icoBoard plugs into a Raspberry Pi, so it's similar to having a SoC. The iCE40-HX8K chip comes with 7,680 LUTs (logic elements.) This means that after you learn the basics and create some simple circuits, you'll also have enough logic elements to run the VexRiscv soft-core CPU (the lightweight Murax SoC.)
The icoBoard also supports a huge range of pluggable pmod accessories:
You can pick whatever peripherals you're interested in, and buy some more in the future.
Every FPGA vendor keeps their bitstream format secret. (Here's a Hacker News discussion about it.) The iCE40-HX8K bitstream has been fully reverse engineered by Project IceStorm, and there is an open-source set of tools that can compile Verilog to iCE40 bitstream.
This means that you have the freedom to do some crazy experiments, like:
You don't really have the same freedom to explore these things with Xilinx or Altera FPGAs. (Especially asynchronous circuits.)

Links:

Second Place:

iCE40-HX8K Breakout Board ($49)

Third Place:

numato Mimas A7 ($149).
An excellent development board with a Xilinx Artix 7 FPGA, so you can play with a bigger / faster FPGA and run a full RISC-V soft-core with all the options enabled, and a much higher clock speed. (The iCE40 FPGAs are a bit slow and small.)
Note: I've changed my mind several times as I learned new things. Here's some of my previous thoughts.

What did I buy?

I ordered a iCE40-HX8K Breakout Board to try out the IceStorm open source tooling. (I would have ordered an icoBoard if I had found it earlier.) I also bought a numato Mimas A7 so that I could experiment with the Artix 7 FPGA and Xilinx software (Vivado Design Suite.)

Questions

What can I do with an FPGA? / How many LUTs do I need?

Had a thought yesterday... (sorry it's a long one).

... About OP_RETURN and the question of allowing large amounts of data to be uploaded to the block chain. I have seen and read various opinions on this. Allow me to add what might be a different perspective to the mix and see what you all think.
~~~~~~
TL;DR: Allowing large OP_RETURN uploads is a form of testing/proving the network, and whilst the demand for lots of small transactions does not yet exist, it (uploading large amounts of data) is economical. As demand for smaller transactions increases, the cost to post large OP_RETURNs will increase proportionately and so those kinds of transactions will slowly become less of the used block space. It's actually a smart way of testing and demonstrating that BSV is open for business. Proving that scaling works on the real network, before it's needed. This reduces the risk for new entrants (users, application builders etc).
~~~~~
When thinking about this yesterday I came to the conclusion that opening up OP_RETURN is actually a genius move. Let me explain.
For Bitcoin to scale we need to support large blocks. By "support" this means the entire eco-system from miners to tools that deal with parsing transactions and data. I'm not sure about you folk, but I can't think of a better way to test and exercise those systems than allowing people to post real transactions with real data attached. Comparatively speaking, you can either stress test with thousands of transactions or a single transaction with a large OP_RETURN. Sure, these are not exactly the same thing, but every day that goes on where large blocks are being produced is more proof that the network can handle large blocks and is able to propagate them. (Testing large amounts of small transactions is also advisable, but that doesn't need to be the primary method for testing block propagation and validation).
People have argued that uploading photos and the like is a silly idea, and even though I think I understand their rationale, I think there should always be the opportunity for people to upload an important file or document or photo is they so choose to do so, and they are happy to pay the fee for it. A free market in action. Miners get to decide how they manage the storage (or maybe in future that's a service provided to miners by someone else). To make sure that the use case works, however, it needs to be (and is being) tested. Plus there's the tools like Bitstagram that are making use of the feature now; creating ideas for new tools.
What all the above does though, and this is the key point I have been pondering, is that it all simply shows that the network can handle large blocks, and as time goes on, likely larger and larger blocks, and that the sky doesn't fall, like has been prophesized by the opposition, especially those that believe every single Raspberry Pi needs to be able to run a full validating node. The fact that the sky doesn't fall and the network keeps on trucking, builds up confidence in the network and its ability to scale on-chain.
Once this happens, the door is open for large numbers of transactions on a proven network. I haven't checked the exact numbers but based on what I see on BTC, a rough back of the envelope calculation yields that, for example, 32MB blocks likely allow for around 80 million transactions per day (with no or little OP_RETURN data), or about 90 Tx/s.
I hear you saying "Wait.... but we can fill up a 32MB block with a relatively small number of transactions with large OP_RETURN data, so we now need even bigger blocks!". But here's the genius part. We don't. At least not for the 32MB to be highly utilized by small transactions. (Of course larger blocks mean more support for of all types of transactions...)
... The available block space is still subject to use by people's willingness to pay the associated fees. In a recent post by Ryan Charles, and IIRC, he was talking about $120 worth of fees to upload a series of about 30 or so, high resolution photos. Fees are still sats/byte. So if people want to do small transactions they can still pay a tiny fee, even if they double or triple the sats/byte that they pay. The effect that this has though (the doubling or tripling), is that now Ryan's exercise to upload the large OP_RETURN data just doubled or tripled in price (assuming competition for block space). In other words, what I am trying to say is that people will always be more readily able to pay for and afford very small transactions (so long as they are not personally making thousands of them), even if others are using large portions of block space though large OP_RETURNS. The cost of posting larger amounts of data will scale up accordingly with the demand for regular transactions. (And even if people are making thousands of transactions, they can still decide how much they are willing to pay for them, in the context of whatever they are doing that necessitates the need to execute those transactions). The Utopian goal is to always have more block space available, or at least enough so that fees stay at a reasonable level.
So actually, whilst the block space is not being used, we shouldn't have a problem with people uploading photos and whatever they want to; it's proving the network can handle it and allowing participants of the network to test and improve their setups based on that usage. Furthermore, there are no doubt people taking notice of this fact, and seeing how BSV is providing something that neither of the other two Bitcoin projects can provide; which is a network that has demonstrated scaling in practice, whilst keeping the approach as simple and as secure as possible.

Spock & CoinEx AMA Recap

Spock & CoinEx AMA Recap

https://preview.redd.it/1lagrcjnc9o31.png?width=1074&format=png&auto=webp&s=3136db9ca685dc17477d307df722e5b73ba80030
Spock Network is a decentralized storage platform. In the early stage, Spock Network mainly stores Proof of Capacity (POC) consensus data to effectively utilize the most suitable decentralization technology to encourage miners providing hard disk space. Recently, Spock has been growing rapidly and getting listed on four famous exchanges including CoinEx. On Sept. 19, CoinEx will launch Accelerator for Spock, allowing users to subscribe SPOK with 0.0075 USD. Besides, in order to help our users to dig more about Spock, we have invited the open source code contributor of Spock, Titian Xie, to throw an AMA among our community. Below is the recap of the AMA and enjoy your reading!

Q1: How will Spock solve the existing problems in blockchain?
A: Spock is a decentralized storage application network. Judged from the current development of blockchain technology, PoC is the only choice for a decentralized incentive mechanism in a distributed network composed of a large amount of hard disk space and bandwidth. On one hand, this solves the problem of excessive power consumption in the current mining industry, and on the other hand, it solves the problem of fair competition among a large number of existing hard-disk mining machines. At the same time, on that basis, Spock also supports Solidity smart contracts, which makes the entire ecosystem more prosperous.
Q2: Could you please say something about the team?
A: The core members of our team are all early users on Bitcointalk forum and developers of Burst. They are very familiar with the technology development trend and the details of the bottom of the blockchain technology. Even I with such a R&D background could only throw myself down at their feet in admiration. Their ideals are also very pure, that is, to make Spock a community coin like Bitcoin and Litecoin.
Q3: Community building has just started. What will you do to build the social media that remain active and continuously focus on Spock?
A: Spock is a decentralized application platform. The community also relies on spontaneous word of mouth. Since Spock was put on the test net and later on the main net, many miners and holders have spontaneously joined in to become owners, and maintained and promoted the community. The upcoming Solidity smart contracts can be carried out by polling among the holders, and members of the community will vote through the smart contract to determine the project function expansion and community governance.
Q4: Spock is a decentralized storage application platform, so what advantages does it have compared with the traditional centralized storage platform?
A: Traditional centralized storage platforms generally adopt cloud storage. Most of the data is stored on a few cloud platforms, which leads to serious centralization problems arising from data accumulation. There are also problems including higher cost, slower transfer rate, and poorer data security. The decentralized storage application platform encrypts and distributes data through a distributed network, meaning that no party, other than the data holder, could get access to the data, thus ensuring security. And one of the key issues is that the open decentralized platform can do better in protecting private data. As with the case of the assets of the digital assets of Huobi, the private key represents the ownership of the assets, and, on the decentralized storage platform, it can represent the disposition and access rights of the data.
Q5: Spock adopts the consensus mechanism of PoC. What advantages and disadvantages does PoC have compared with PoW and PoS?
A: In terms of resource usage, PoC is just between PoW and PoS, unlike PoW which consumes a lot of power, or PoS that almost costs nothing. Besides, since the core mechanism of PoC is similar to storing the “hashrate” of PoW on the hard disk, it also makes it possible for the mining equipment to mine in different projects at the same time, provided that several different projects use the same data structure.
Q6: We noticed that Spock also introduced the PoS mechanism on the basis of PoC. What is the consideration?
A: With the POS mechanism added in SPOCK, when a miner package a block, if its address balance satisfies the condition, he or she get get all the proceeds; otherwise, the proceeds will be reduced, and those that fail to meet the conditions will be destroyed. So in my opinion, developers introduce POS mechanisms to create a more equitable and sustainable ecosystem.
Q7: What will the team do to attract more developers to join the Spock ecosystem?
A: Spock is the first public link that supports the Solidity Smart Contract and has been put on the main net. It allows developers to port the DApp on the Ethernet to the network at a very low cost, while developers can design the mining and pledge mechanisms for the tokens of PoC distributed on this network.
Q8: What is the form of Spock mining? What are the conditions for miner application?
A: In SPOCK, mining is carried out through the storage device. First, you write the result of the hash calculation to the device, and reduce the huge hash calculation required in PoW algorithm by retrieving the data in the hard disk. Only a small amount of hash calculation will be required in execution stage. You can mine as long as you have storage equipment and meet the hashrate conditions. Ordinary miners just need an ordinary computer with a hard disk and access to the internet, then they need to go through hard drive mapping, download the wallet, install nodes and so on before mining.
Q9: I am a Windows phone user. How do I download a SPOK wallet?
A: At present there is only the Android version. Versions of other platforms are subject to the official arrangement.
Q10: Miners don’t know how much hashrate they have or how much they could pledge.
A: Check http://www.spockpool.com. There is a calculator to check the amount of pledges required for the time being.
Q11: Does the mining cost anything or a certain amount of SPOK tokens?
A: Now we have a market for cooperative mining. Miners can borrow tokens from owners for mortgage.
Q12: Is there a detailed tutorial for mining?
A:https://www.spockchain.org/download/SpockChain%20Mining%20Tutorial%20V1.3.2.pdf
Q13: What are the advantages compared with Lambda or such? The larger the hard disk, the higher the hashrate?
A: My suggestion is to experience the mining process on both official sites so you may understand the differences between them.
Q14: Can we use the Raspberry Pi to mine at home?
A: Yes, theoretically. Yet the weak computing power of Raspberry Pi itself may affect efficiency in hard drive mapping.

This is the end of the sharing. See you next time!

A 14-year-old's experience with Bitcoin

First-time poster here, don’t bully me, apologies for the potentially atrocious formatting :) TL;DR at the end
So in the wake of Bitcoin’s explosive rise in value and media attention, I’ve been encouraged by others to share my experience over the past few years as a miner. Here's my story (it's kinda long, you've been warned)

Humble Beginnings

It all started almost three years ago in the beginning of 2015 when Bitcoin flew under my radar. Looking into it, I admittedly wasn’t drawn in because of the decentralisation or the anonymous payments, I was hooked on the idea that anyone could get their hands on some just by running a program and leaving it to do its own thing. I know, how shallow of me. But the idea of making even a bit of money without ‘any work’ was convincing enough for 11-year-old me to do more digging into the matter.
To my disappointment, I soon found out that the era of mining Bitcoins with a PC’s CPU or GPU was long obsolete and instead it was all ASICs at that point.
So that summer, for my twelfth birthday, I got a little ASIC machine for €60, an Antminer U3. This little thing took up less space than a graphics card but could mine at 60 GH/s. Because, at the time, I didn’t have a controller device that could be kept up and running all day long so it could run the program that mined Bitcoin using the U3, I went ahead and got a Raspberry Pi. After setting up the Pi and installing all the necessary stuff (took an awfully long time), I connected it to AntPool and plugged the U3 in. Two days past and the mining pool sent the first Bitcoin I ever received to my wallet (I was using Blockchain.info). It was just 30 cents worth of BTC but I felt a bit of a rush because I was earning a bit of money through this completely new thing and the idea of that was thrilling.
Let’s back up for a second. I just used the term ‘earning’ as if I was profiting, and naive me 2 years ago was no different. In reality, I was at first oblivious to the fact that I was most likely LOSING money overall because of how much energy that little sucker was taking in. But, I was comforted thinking that using that machine was just a practical way of learning about this modern currency and that the loss of several cents’ worth of energy was acceptable in the name of education and learning.
Fast forward ten months to the wonderful summer of 2016. I had recently turned 13 and the Antminer U3 had been running on and off throughout. Various pauses and breaks in mining would be observed, as I had to manually get everything up and running after frequent breaks in the Internet connection. You’d expect my newly-turned-teenage brain to lose interest in Bitcoin as it does with many other gimmicks, but – even surprising myself – I miraculously didn’t. Good thing I maintained interest thinking about it now, not so good at the time for my parents. Why do I say this? I felt like it was time to get a little upgrade in my hardware.

Getting an upgrade

Days passed with me comparing every ASIC miner I could at that price point. It was then I set my eyes upon the Antminer S7 (same folks who did my U3, nice). I had put it up against a plethora of other miners and I figured the S7 was my best bet; the thing costs only about 10 times that of my U3 but could run at 4.73 TH/s, almost 80 times as powerful. The only problem being its power consumption was at 1300 watts, which would put a massive dent in the electricity bill and eliminate any profit I would make. Fortunately, I had a secret weapon up my sleeve – or rather my mum did. She had rented out an office outside our apartment where she would keep files and paperwork. The office’s electricity bill was a flat rate as far as I’m aware and it ended up being my saving grace because it virtually got rid of the “oh no I’m actually going to be losing money because of how much electricity I’m eating up” factor, making this whole hardware upgrade viable.
After convincing my parents, they finally agreed to shell out the requested amount, with the initial investment being paid back with time. I went to a local Bitcoin vendor and purchased 1 BTC for about $665 in cash (sigh yes, I know. $665 dollars). Shortly after, I used about 0.9 BTC to purchase the Antminer S7 and a 1600W power supply for a grand total of $600. The products would be made and shipped from China so I was definitely in for a wait.
A month passes and the package arrives at last. I connected all the wires from the power supply into the S7 and – with great anticipation – I plugged it into the wall to start its first ever run. And what do you know? An extremely loud and high-pitched whirring sound blasted out from the fans on both the power supply as well as the S7. After killing the thing, I questioned my choices. I couldn’t dare put that thing anywhere near my mum’s office in the event it drive everyone in the building absolutely nuts. I was at a loss. However, I soon recovered from my temporarily debilitated state and got working on a solution.
The first idea that came to my mind: change the fans. The stocks fans were by Evercool and spun at around 3000 RPM. The power supply used a small, robust fan that looked like a cube that must’ve spun at extremely high speeds judging by how high the sound it produced was. I got my parents to give me some more funding so I could acquire the replacement fans and I did. Bust. After installation and testing, none of the fans would work. I managed to configure the S7 to connect to my Antpool account and the machine would manage mining for several minutes running at peak performance but ultimately be automatically cut off because of how hot the machine was getting (I’m talking about 80 degrees Celsius kinda hot in that thing). The fans got refunded and I was back to the drawing board.
After combing through some forum posts and videos, I came across this video and a forum post in which people have their mining rigs placed inside a ventilated, muffled cabinet. Undertaking a project like this would be time-consuming and risky but I had no better ideas so I decided to go through with the idea anyway.
Firstly, I sought out a cabinet with suitable dimensions. I managed to get just what I needed at a second-hand IKEA shop. Great. Secondly, I went ahead and acquired some sound-absorbing acoustic foam from a local provider. Fantastic. Finally I had to get a ventilation system going within the cabinet, otherwise, all the hot air would roast the machine alive in there in a bloody mess. With the help of my dad, we found a pair cabinet fans on the Internet that were close to silent but could circulate the air well enough.
Eventually, all the materials came and, with the help of my parents, put everything together. The process took quite long time and we had a couple hiccups along the way, but we got it done and it came out pretty nice.
The moment of truth came and, to my relief, it ran so much quieter than without the cabinet. It was nowhere near silent but it reduced the noise a great deal. Soon after, I got the thing into the office and set everything up from there. Unfortunately, I was forced to underclock it because you could still hear the machine’s whining from outside the thin office door. Gunning the hashrate down about 25% to 3.7TH/s, I could lower the fan speed without risking the machine burning up. Sure, I wasn’t getting the full potential of the machine but I didn’t complain because electricity was not an issue there and it was still a whole lot better than my U3. With it up and running, I could leave it there, periodically checking to see if it was mining on Antpool.

The aftermath

In the months that followed, I was getting a solid $2.5 worth of BTC on daily basis. Half a year later, May of 2017, I had accumulated a satisfactory $600. I thought, “At this rate, I’d be able to pay my parents’ investment back in a few months” (the total investment came close to $900). Bitcoin had risen to over $1500 so I was already over the moon at that point because of how well everything was going. Little did I know…
I hit 0.5 BTC midway through September this year. The price of BTC had dropped after a sudden rise to $5000, but I couldn’t have asked for more. Although I possessed only half the amount of BTC I paid for the machine, its value was over twice that of the initial investment. I thought BTC would level off at around $4000 but nope.
In the month of October, the price skyrocketed. Since September, I had only mined 0.017 BTC but the value was already over $3000. It was just a matter of selling it, but I decided to hodl. Good thing I did.
As of November 5, I have approximately 0.52 BTC mined in total from my S7, valued at $4000. If I were to sell it right now, I’d have a profit of over $3100. And as for my miner, it’s churning out 0.0006 BTC daily, sounds like nothing but it’s still the equivalent of $5 today and I couldn’t be happier, at least with the miner and Bitcoin.
You remember that $665 for 1 BTC that I mentioned earlier? In hindsight, it would’ve been such a better idea to just keep that one Bitcoin and not do anything with it until today (in the interest of making much more money), as I’d theoretically have upwards of $7000. The idea of that still haunts me sometimes if I dwell on it too long but knowing that I’m in possession of an already hefty amount, the pain of it had numbed slightly. It’s not all doom and gloom for me from the exponential increase in Bitcoin’s value, however. Those first $0.3 payments from my humble little U3 all those years ago now are now the equivalent of over $6 today!
Bitcoin and everything it encompasses has been and still is a journey of discovery and an adventure. Looking back, starting with a modest €60 Antminer U3 to having a sum of Bitcoin equivalent to two extremely high-end gaming rigs (first thing I could think of as a comparison, sorry) has been something I can’t really describe. Through the course of the past few years, I’ve learned more about technology, I’ve unexpectedly gotten insight into economics and business and – of course – I’ve made a lot of money (if I decide to stop hodling that is).
Also, props to my parents for keeping an open mind throughout, I know some parents would be horrified at their kids being involved in something that has been used in some less-than-savoury ways and it's great knowing mine have been supportive all the way.
TL;DR got into Bitcoin mining 3 years ago at age 11 with an Antminer U3 that ran at 60 GH/s, got an Antminer S7 (4.73TH/s) and built a sound-muffling, ventilated cabinet for it. Am sat here today with $3000 profit if I decide to sell right now.

Lightning!

Lightning Network
Today I am going to talk about the “Lightning Network” which is a proposed solution to the issue of scaling Bitcoin faces. Lightning Network (I will use the acronym “LN” to refer to the Lightning network from this point forth) LN has its fair share of criticism in the crypto space. Some claim its brilliant, while others claim it is the antithesis of what Bitcoin was supposed to be. I am going to try my best to touch on the reasoning both crowds use to come to these conclusions. First things first, lets discuss how the whole thing got started.
The LN was first proposed in 2015 by Thaddeus Dryja and Joseph Poon in a white paper they wrote (White paper for LN can be viewed at the following linkhttps://www.weusecoins.com/assets/pdf/library/Lightning%20Network%20Whitepaper.pdf ) They decided that Bitcoin has a scalability issue and were looking for the best way to solve that issue without ultimately sacrificing the fundamentals that make BTC such a great currency. They decided that building a 2nd layer on top of Bitcoin was the best solution (rather than another useless hard fork to add to the 103 or so other Bitcoin forks out there) Many claim that coins like Bitcoin SV and Bitcoin Cash are the solution to scaling issues, but they are forks and centralized when compared to Bitcoin which sacrifices decentralization for scalability. Lightning is different than a fork as it is basically a payment channel that connects 2 or more parties directly. This makes payments almost instant, which is something people using Bitcoin core have desired since its creation. How does it work? Lets discuss that!
How does the Lightning Network work?
Okay so you have been hearing your friend Phil go on and on about how great the LN is, but why is he so excited? Lets figure it out! The LN is a payment channel that is set up between 2 or more parties. They start by creating the payment channel which is a multisig wallet (a multisig wallet is a BTC wallet that cannot be accessed by just one party as it takes “multiple signatures” to access the funds. Now that Phil and I have set up the payment channel we can now transact with each other as much as we like with no transaction fees (until we close the channel). The payment channel gets updated every time a payment is made. So if Phil and I have 2 Bitcoin on the channel, lets say I have 1 BTC and Phil has 1 Bitcoin in the multisig wallet me and him created for the Lightning channel. I could send Phil ½ of a BTC and the ledger would show that Phil now has 1.5 Bitcoin while I only hold .5 Bitcoin. This transaction occurred off the Bitcoin blockchain so it avoided the hefty transaction fees that accompany Bitcoin core transactions at times. The channel can be left open and the ledger will update every time me and Phil transact with each other (until we decide to close the channel) This layer makes micro transactions more feasible as people are not paying a 3 $ transaction fee for a 1$ transaction.
People that would like to use the LN can get a node (Casanode, Raspberry Pi 3 etc.) which will also act as a BTC core node along with a lightning node. This is a popular way to be a part of Lightning payments. It is not the only way though. There are wallets that can be used to access the LN without having to own a casanode or raspberry pi. You can still use the LN without owning a casanode by downloading an app like “Blue Wallet” which will allow you to access LN without necessarily owning a node. Apps like this make LN more available to the general public that may not quite grasp the reason people own casanodes. Either way removing barriers that could potentially hinder people from using LN is a big part of wide spread adoption. Lightning is still in its infancy really so more and more apps should pop up similar to Blue Wallet in the near future. (This is not an endorsement of Blue Wallet, I simply used it as an example) If you would like to order a casanode it can easily be found with a simple google search. I personally know a few people that paid for the node and most of them did it just to help the LN network grow and to actually be able to use it! They typically run for around $300 USD. (I see the price going down in the future as LN becomes more used and the casanodes become more in demand)
Now just because you aren’t connected to someone directly through a payment channel you can still send payments to someone in many cases. So, Lets say Phil and I want to transact with each other but we don’t have a channel connecting us. We could utilize a 3rd party to connect the payment channels. For example, I am trying to send Phil 1 BTC, but we don’t have a channel set up, but we want to transact with each other. The node will find the fastest path it can to Phil so I do not necessarily need to create a channel with him. We could use anyone to bridge the gap and transact with each other in this way. This is referred to as a “Hop”. Some people may worry that the link between me and Phil may act maliciously and attempt to take the payment, but that’s the beauty of LN. It can’t be taken in this way. So I send Phil .1 BTC. A 3rd party would first receive the .1 BTC and would send it to Phil automatically. The 3rd party cannot stop the transaction in the middle if he were to try and steal the funds. LN doesn’t allow that.
LN offers almost instant payments with Bitcoin (and soon many altcoins will also utilize LN) with minimal fees. Some think the LN is absolutely a terrible idea. They believe transaction fees will be severely diminished in the wake of LN due to the fact payments made on LN do not post to the BTC chain until the channel has been closed charging a one-time fee for multiple transactions. I would say that with LN we will see a surge of new adoption that will increase the use of BTC and in the long run should increase the amount of transaction fees collected by miners for the work the perform. People like to claim LN is centralized and the antithesis of what Satoshi was thinking when he created BTC. I have to say I disagree. LN is a layer on top of BTC. It doesn’t effect the fundamentals of BTC core and that is important to me and many others. Bitcoin is a work of art because of decentralization. LN doesn’t hinder this. It is simply an option for people that want BTC payments faster to have a means to do so. In the future people will most likely do plenty of transactions on LN (I think most dealings will be done via LN) But the big transfers will still likely be done on BTC core itself. Bitcoin is a work in progress and LN is a step towards adoption.
Right now, LN is very new and still untested in many ways. It is an experiment in my eyes that is likely to succeed. Even if LN went belly up tomorrow BTC will still be here. I have a lot of faith in LN and I think it will be a huge part of mass adoption in the future. Nobody can see the future… But we can speculate! I enjoyed writing this and I hope you learned something. I sure did.

Let's Talk About Litecoin Nodes

I decided to write this up because there's a lot of confusion about what a "Node" is. I personally had to do a lot of research to figured this out myself. If anyone would like to suggest edits, I welcome them.
Due to the decentralized nature of Litecoin, sometimes key terms or definitions don’t get standardized. This is particularly problematic for newcomers who want to learn about Litecoin but get confused by variant vocabulary. For example, a Full Litecoin Node to one person may mean something slightly different to another. In light of this, below I suggest a list of terms to help the community use the same definitions and language in regards to Litecoin Nodes.

A Node

Before we talk about Litecoin Nodes, let’s talk about nodes in a broad sense. In a distributed network, the simplest way to define a node would be to say it is a point of intersection or connection with the network. It can act as both a redistribution point or a communication endpoint. This loose definition helps us better understand the different ways a Litecoin Node functions within the Litecoin Network. The following definitions should collectively be considered Litecoin Nodes.

A Full Node

A Full Litecoin Node is an integral component of the Litecoin Network because it validates the blockchain. It does this by downloading a copy of it. It is also capable of relaying transactions and recent blocks, but this isn’t required to be considered a Full Node. Now when you first open up a Full Node client like Litecoin Core, most people are sitting behind a firewall. In this case, your Full Node is limited in the number of connections it can connect to (around 8) and only looks for Super Nodes a.k.a. Listening Nodes. The reason for this is because your Full Node isn’t publicly connectable yet.

A Super Node a.k.a. Listening Node

In a distributed network, a Super Node functions as a highly connected redistribution point as well as a relay station. Therefore this would be an appropriate term to describe a publicly connectable Full Litecoin Node. This means many nodes can connect to it to obtain relayed transactional data and blockchain history. This may require more bandwidth and CPU than a Full Node because of all the extra work it’s doing. These Super Nodes are normally on 24/7 and are reliable focal points for other nodes to connect to. In order to activate this within a Litecoin client functioning as a node, you must make it publicly connectable. One way to do this is to bypass any potential firewalls and/or setup port forwarding. Some manuals suggest running litecoind(litecoin daemon) in the background instead of Litecoin-Qt, but this isn’t necessary.
u/aaron0791 Raspberry Pi guide can either be a super node or a full node depending on whether it is publicly connectable. You can run it with the litecoind as well in order to avoid setting up a GUI with the Raspberry Pi.

A Miner’s Node

Today, miners utilize mining programs separate from Litecoin Core to mine Litecoin blocks. Some miners choose to solo mine and therefore use their own Full Node to maintain a full copy of the blockchain via litecoind. Others choose to pool mine and work together to solve blocks. In this case, the admin of the pool maintains a Full Node while pool miners contribute their hashpower. A third method, though highly discouraged and harmful to the network, is to SPV mine by mining on top of blocks before fully validating them. These SPV pool miners typically trust another mining pool’s Full Node as a reference to build on top of. In light of this, a Miner’s Node can be further subcategorized as either a Solo Miner’s Full Node or a Pool Miner’s Full Node.

A Simplified Payment Verification(SPV) Client a.k.a. Thin Client a.k.a. Light Wallets

SPV clients like Loafwallet (the Litecoin App for smartphones) are not Full Nodes because they don’t download the blockchain. SPV clients do this by ensuring your transactions are put in a block and then confirm that other blocks are being added to it. Therefore in the loosest sense, an SPV Client may fit the criteria of a node. However, they don’t do much to support and validate the distributed trustless ledger of Litecoin. Instead, they store just copies of all the headers of all the blocks in the blockchain that are taken from other Super Nodes. Therefore, SPV clients are unable to verify any transactions in the chain because they don’t have access to it. In this way, they function as communication endpoints as they are are unable to relay transactions or blockchain data. Additionally, it is important to put your own full nodes behind them to securely use SPV clients as wallets.

Specialized “Edge Routing” Nodes

Other types of nodes exist where Full Nodes are stripped of its wallet and mining capabilities. Entities such exchanges and merchant payment processors then build on top of these specialized “edge routing” nodes.

Conclusion

Above, I’ve briefly described the various roles a Litecoin Node can have. I’ve also included a broad overview of the necessary steps a user would need to take to use Litecoin Core in these roles. Hopefully by providing this list of terminology, it will empower users to understand what exact role they are playing in the network and to inform them of the steps they can take if they want to play a different one.

Dark Net/Decentralized Net, Hypothetical layer 2 solutions for DEX's, phone nodes/MeshNets

There was an incredibly important episode of Max Keiser today, the second half he interviews a Venezuelan entrepreneur who is building encrypted meshnet nodes that can send bitcoin transactions and encrypted messages with 3g and 4g without sms, in places that are heavily censored, offgrid, or out of power, they also said you can repurpose old bitcoin miners into these things as well.
With the direction that governments are going, I think it is increasingly important to seperate the blockchain from the internet backbone itself by using meshnets (and to ultimately make Tor and exchanges a part of it as well)

In any case to the point- G20 summit recently said that they more or less plan to wage a global KYC AML war on cryptocurrency. Many of their proposals undermine the entire privacy and safety of crypto and are antithetical. They are proposing building parallel identity associated traceable refutable, mutable systems and barring countless people out of the economy globally. They could try to break constitutional rights to put backdoors in open source software developers, to persecute miners, node operators, software and wallet releases like Wasabi. And now with FATF, the exchanges will lean towards, they will have a motive to simply ban non compliant or non identity attributed 'smart contract' wallets, a defacto ban on peer 2 peer anonymouty. Countries would attempt to force these wallets onto people and they would essentially have their bitcoin trapped in a statist parrallel bitcoin ecosystem with no way to send money to anonymous wallets, they would attempt to ban and regulate normal wallets and hardware wallets and to ban VPN and Tor, to seize DNS and domain.

IT's very easy to cencor crypto and thus money and economic freedom, because the stupid Decentralized exchanges have seizable servers, addresses, business, name, etc, and the order book and matching engine require a server adn resolver, and have temporary custodianship over crypto assets, happenoff chain, etc.
What is needed is a real time atomic swap over a decentralized DNS/servecomputation like with IFPS/ZeroNet/Namecoin/Blockstack, but there definitely needs to be hostable nodes, proliferated meshnet node phones. I think ethereum 2.0 scaling will be the breakthrough moment for speed/size, etc.
This tendency towards controlled DEX like Binance is just utterly unsustainable and needs to be readily undermined, but it will require the merging of many blockchain systems with meshnet strategies.

I am trying to gain some insight into what people are working on and envisioning for a lot of the coming layer 2 solutions in regard to a broader decentralized ecosystem, notably for DEX and smart contracts.
-How can layer 2 aid and help the concept of something like Ren VM where you have decentralized computing and smart contracts privately interacting with liquidity pools?
-How is layer 2 going to strengthen the feasibility of proliferating full nodes on raspberry pi and phones, and will it help DEX?
I feel like a really big issue like a front and center issue is the reliance of exchanges on a central server for orderbook matching and offchain settlement, margin, colateralization, the data involved. Non custodial wallets aren't enough. The central servers are a vector point for centralization, counter party risk, over reliance upon high capital institutions.
Arguably bitcoin needs something much more decentralized, that could be achieved with layer two solutions that either integrate with or emulate things like namecoin, ethereum smart contracts, and the new Ren VM tools. The biggest issue is of course speed and scalability.
The server function and data of these exchanges should be held inside smart contracts because its more secure, it seems like a virtual machine approach is in fact a better way to go about the challenges of linking liquidity pools and orderbooks.
There's also a project from back in the day called Gridcoin. It was or is used to link up computer processing power for science applications and scientific engine rendering solutions for modeling things. Richard heart is making a project similar for science applications.
I believe this is a much more secure way to approach DAPP's and layer 2 protocols, to get virtual machines that are not located on central servers to help process a lot of the advanced needs of the network, to slowly make the entire exchange and reliance of these failurepoints of bitcoin to be a part of the bitcoin protocol itself, to remove the ecosystem itself away from the clear net and central servers, and to begin to upload it into satellites and proliferated phone nodes.

Bitcoineum: Virtual mining on Ethereum

Hi Guys,
I'm officially announcing that I have started mining Bitcoineum on the Ethereum network as of 4:00 am EST July 19, 2017, and anyone is free to join me. This is a fair mined, no founder's reward, no premine, no hidden shenanigans token. I was going to make this public announcement even earlier but due to scheduled travel I wanted to make sure I was available to answer questions if there were any.
Bitcoineum attempts to duplicate the value preserving aspect of Bitcoin and bake it into the Ethereum network as an ERC20 Token while employing a completely novel virtual mining system. Think of it as a modular base token that abstracts the mining, and has functionality for converting into other types of tokens and systems as the ERC20 infrastructure evolves. A transferrable proof-of-burn that is designed to bootstrap a value store right onto the Ethereum smart contract network. A simpler and more straight forward approach than trying to attach a separate smart contract network to your value store, such as what is happening in Bitcoin right now.
Further, anyone who has Ether can mine Bitcoineum from a web interface right now without any special hardware. That means device independent mining, mobile phones, the web, embedded, raspberry pi, whatever. I wanted to create a fair, equitable, distributed and accessible mining system that can drive value into other tokens. The example web miner works but is very bare bones, and needs further improvement but anyone can build a miner that interfaces with the smart contract. I can imagine a very sleek front end built around it to start, but the actual mining algorithm can be tweaked to try and optimize returns. A little bonus for the people interested in algorithmic trading. I am also actively working on a mining pool contract that will aggregate multiple users which will both increase the likelihood of mining the block, and proportionally increase the reward. The idea that other contracts will drive mining in the future is central to Bitcoineum. The possibilities behind that are very interesting and could help create actual on chain financial products.
You can read more about it, including motivations, technical white paper, and other general information at: http://www.bitcoineum.com/
You can check out the Solidity smart contract code, testing harnesses, and miner frontend at http://www.gitlab.com/mbrix/bitcoineum Pull requests gladly accepted. If you have the chops to security audit the contract code I'd be glad to hear your feedback.
You can start mining directly with a locally unlocked Geth/Parity node, and the web miner at http://www.bitcoineum.com/mine It is web console based, and tested mostly on Chrome. The one feature that is worth noting is that you can set the credit account to a cold wallet address, so you can limit the funds the miner has access to in your unlocked geth instance and still securely deliver any mining rewards to cold storage directly. I recommend doing this to limit any potential loss of funds due to bugs, misconfiguration, etc. I don't want to get reports back that someone lost a million ether on their unlocked instance because of a hack or a silly bug. Keep the accessible miner account limited, and verify the contract address on the transactions being done.
If you are concerned about the integrity of the web site for some reason (it is completely statically served on S3) you can run the miner directly from the git repo, although that's a bit outside of the scope of this post.
It is also possible to mine using MetaMask, but without being able to unlock your wallet it is extremely tedious. Once this is addressed upstream it will not be necessary to run a local node to mine Bitcoineum, really easy decentralized mining. Currently I disable metamask/parity chrome client when mining since they tend to interfere.
The contract address is 0x73dd069c299a5d691e9836243bcaec9c8c1d8734
Finally, a quick word about proof-of-burn. There was a rigorous debate about it's merits last time I released a token for registering Lost ether. I am a strong proponent of proof-of-burn as a substitute for proof-of-work, but I am cognizant of the argument that there must be a reason to exist beyond simply store-of-value, deflationary, fixed cap semantics. Although, I believe that Bitcoineum's structure is useful and complementary to inflationary Ether, I've taken it one important step further. I think there are several things about an ERC20 token that we are only beginning to explore. You can think of it as an atom in a larger structure, a building block towards more sophisticated capabilities. Bitcoineum's user-oriented mining and value semantics are meant to serve as a base token for a wide range of other applications. I've built a simple but effective interface into the token called Transmutable. This let's one Bitcoineum seamlessly turn into other ERC20 tokens that have yet to be created. The value burned to create Bitcoineum can than transfer directly into these other types of tokens in a standardized way. A a tangible example users could migrate value into a successor ZkSnark Bitcoineum token once that functionality makes it into Etheruem. So the value store itself can directly be used as an input into more advanced tokens. This is both new and novel functionality, that when combined with it's other properties makes it a worthy thing to mine. Please join me :D.
I'll be around for a little while to answer questions, but I'm also on the road the next few weeks, so if I'm slow to respond to pull requests for the awesome new miner your wrote please be patient. You can email me at [email protected], reach me here on Reddit, or come at me on twitter @brantonbits. Despite the testing and work I've put into it this is still a beta product, so you mine at your own risk. I'm hoping this makes a useful addition to the Ethereum ecosystem, and chips away at the idea that Bitcoin can survive simply as a store-of-value when developers can create these types of systems right on Ethereum.

The 8 most informative comments about 21inc's bitcoin computer dev kit

"Anyone who thinks this is about making money by mining has very little insight into what Bitcoin actually offers the world. This is not about bringing the old economy (banks, businesses, governments) into the Bitcoin family. This is about building entirely new economies, ones that have never and could never have existed before. 21inc can see the vision and they just bootstrapped the IoT on the Bitcoin blockchain. Thank your lucky stars on your way to the moon." - PhiMinD
"I'm fairly sure this is NOT an end user device. This device appears to be solely for the purpose of prototyping integration with other devices, and allow people to work out the ends and outs of the process. My assumption is that in like 6 months to a year, a much more compact and integrated device will be released that would be far cheaper, and suitable for installation in actual consumer devices. This is for developers." - DakotaChiliBeans
"The more I think about it, the more incredible and groundbreaking this seems. When every piece of hardware and software has the ability to transfer money, our entire concept of how we do everything changes. We're only beginning to imagine the possibilities. Even the few simple ones I've been thinking of make my head spin. Bitcoin as a human currency is exciting. Creates a more open system, breaks monopoly, gives you the option of true, non-revocable ownership. All great stuff. But it's these revolutionary ideas that make me believe that Bitcoin, or a successor very much like it, will take over the world. As someone invested in bitcoin, I'd like to see it succeed and my investment pay off, but goddamn will this be an exciting ride regardless. At this point, I'm seriously thinking of buying and developing on it. The potential here is lightyears beyond what most people are thinking." - consideranon
"Seeing the 21 Bitcoin computer reminds me of the developer kits for oculus rift. It took a lot of time to perfect before going fully public. It was also tested with a pre-release through Samsung's VR headset. Other more resourceful people bought the cardboard much like the same people would buy the Raspberry Pi instead of this. Anyway, the 21 computer is very likely the first iteration of many." - Hiro_Y3
"I think it removes a step in the process. Instead of learning about wallets, private keys, maintaining a login and password, etc, the computer takes care of all of that without the user having to think about any of it. The mining function provides initial liquidity to get the ball rolling. This is the first step of payments being built into the IoT." -TDBit
"Most of everybody here is missing the point. This is a bitcoin computer. This is not made to simply mine to generate a profit but rather a miner is just an added part. The miner is used to continuously supply the Bitcoin computer with bitcoin. It uses the bitcoin to "write" to the blockchain. It's like a digital quill with an endless bitcoin inkwell." -Fuzzypickles69
"Ok, this takes a leap of faith, but what they're trying to do is build a full-stack device which can send/receive bitcoin and which also solves the "how do devices get bitcoin in the first place" problem. Imagine the whole thing being a lot smaller and cheaper, and embedded in lots of devices globally. Now you have a world in which millions of devices (machines) can send and receive tiny payments, and which natively have a currency unit to use for that purpose." - melbustus
"ServiceXYZ: Links your 21 box to your Twitter account, and any paywall website lets you read anything you want without popups, ads, or subscriptions. There, I just made up a business in 10 seconds, someone go make it :)" - evoorhees

LYNX: AN ECO-FRIENDLY CRYPTOCURRENCY

Lynx is a new Crypto project that is solving and tackling one of the biggest problems in crypto-currencies and that is the cost to maintain and run the network normally called, “mining.”
AN ECO-FRIENDLY CRYPTOCURRENCY
Bitcoin’s business rules and energy requirements create an over-reliance on fossil fuels; Lynx does the opposite and strives to solve this problem. For cryptocurrency to be considered a secure platform for exchange in today’s global marketplace, it must be created with global sustainability in mind.
GLOBALLY SUSTAINABLE NETWORK
Unlike Bitcoin, the Lynx code discourages high-volume mining rigs because the code purposefully lacks incentives to mine it for profit. As a result, the entire Lynx network is designed to operate on a collaboration of low power devices that anyone can run, resulting in a collective global mining cost of only dollars a day.
From Lynx’s white paper:
LYNX CREATED THE HYBRID PROOF OF WORK SOLUTION. LYNX BUSINESS RULES ENCOURAGE THE USE OF LOW-COST COMPUTING (LIKE A RASPBERRY PI WHICH ONLY CONSUMES AROUND 3 WATTS OF ELECTRICITY) TO MINE THE COIN. AS A RESULT, THE ELECTRICAL COST TO MAINTAIN THE LYNX NETWORK IS A FRACTION OF BITCOIN’S, YIELDING A LOW ENVIRONMENTAL IMPACT. THE EMPHASIS ON LOW-COST COMPUTING ALSO CREATES A MORE DECENTRALIZED, BROAD MINER BASE WHICH STRENGTHENS THE STABILITY AND SECURITY OF THE CURRENCY. AND, THE EASY-TO-USE TOOLS AND BROAD MINER BASE CREATES A MORE EQUITABLE CRYPTOCURRENCY THAT ANYONE CAN USE FOR GENERATIONS TO COME. LYNX WAS DESIGNED TO HAVE MINIMAL ENVIRONMENTAL IMPACT BECAUSE IT’S COMMITTED TO CREATING GLOBAL SOLUTIONS AND MAINTAINING A SMALL CARBON FOOTPRINT.
FOR A CRYPTOCURRENCY TO BE CONSIDERED ECO-FRIENDLY29, THE ELECTRICITY REQUIREMENTS TO RUN THE GLOBAL NETWORK (INCLUDING THE HARDWARE AND SOFTWARE) MUST HAVE A MINIMAL IMPACT ON THE ENVIRONMENT.30 TO ENSURE ENVIRONMENTAL SUSTAINABILITY, LYNX DEVELOPED HYBRID PROOF OF WORK (HPOW). LYNX HPOW STILL USES POW ​BUT MODIFIES IT SO IT ISN’T PROFITABLE AND, AS A RESULT, CREATES AN ENTIRE CRYPTOCURRENCY NETWORK THAT CAN RUN ON ENERGY EFFICIENT, EASY TO SET-UP, LOW-COST COMPUTERS OR CLOUD SERVICES. THIS REMOVES ANY BARRIERS TO ENTRY FOR NON-TECHNICAL INDIVIDUALS OR ORGANIZATIONS WHO WANT TO GET INVOLVED WITH, SUPPORT, AND BUILD APPLICATIONS ON A STABLE AND SECURE CRYPTOCURRENCY PROJECT.

Making pooled mining immune to 51% attacks, selfish mining, etc. by bundling an SPV client into mining software.

This idea has been floating in my mind for a while, but I haven't seen anyone else mention it. Figured it was worth discussing.

The problem

The threat posed by pools is that they indirectly control large amounts of hashing power. Miners are mining blindly on whatever header the pool gives them, and hence can be made to attack the network at their leisure.

GetBlockTemplate

GetBlockTemplate was supposed to fix this problem by allowing miners to do their own transactions (and making what they're mining completely transparent). This works, but adoption is low for a few reasons:
TLDR: GBT is a great way to neuter the ability of pools to do bad things™, but it isn't widely deployed due to the resource requirements and setup effort of using it properly.
Most/All the big threats posed by a large pool boil down to:
In both cases, the fact that this is occuring is actually detectable regardless of mining protocol (getwork,stratum,GBT), because the parent block hash is part of the header the miner is hashing. So the information you need to know whether you're being used to attack the network has been available all along.

The suggestion

By bundling an SPV client into mining software, all miners can verify that they're building on top of a block that is:
  1. Known to the network (blocking selfish mining).
  2. The tip of the longest chain (blocking orphaning of other blocks/51% attacks).
If this isn't the case, they can switch to their backup pool.

Advantages of the approach:

Disadvantages:

Does this work, or am I missing something obvious?

FOR IMMEDIATE RELEASE: After Butterfly Labs collapses, engineers find new jobs at 21 Inc.

BEGIN BLOG POST

After Butterfly Labs collapses, engineers find new jobs at 21 Inc.

A bitcoin miner has shipped on time. Yes, that is news. A new venture-capital backed company, 21 Inc., has released a miniature bitcoin miner that they call a "Bitcoin computer". For $399.99, you get a Raspberry Pi, an SHA-256 ASIC board, and a giant fan.
Again, this is news: normally, a manufacturer of bitcoin miners would overdesign and underengineer their equipment, or, if they managed to ship something functional, it would be so poorly engineered -- and over budget -- that it be an explosion waiting to happen and/or priced comparably to a four-door sedan.
21 Inc. has done something remarkable in the Bitcoin world: they started a company that operates like a legitimate business. They're even listed on Amazon.com, a company that's so strict with vendors that Nintendo was kicked off their system for not kissing enough customer ass.
Okay, enough with the praise.

This thing sucks.

The 21.co "computer" certainly deserves a place in the VC world, along with the other products consisting of wild promises and inane use cases. For the price of 4 Raspberry Pi computer kits, you get the following:
(If you have a remote desire to develop applications that use bitcoin, stop here. Go through that list and buy just those items above. You don't need anything else. If you're looking for comedy, or if you're a sucker with too much money, read on...)

Is that all I get for my money?

Those products alone don't allow you to make Bitcoin applications, apparently. You need these things, too:

How about the software demos?

It's difficult to justify developing a $400 computer that can't do much. So, to entice some customers, 21 Inc. included demos that try really hard to make customers feel inspired. Here are just a few things that 21 Inc. claims were totally impossible before their product existed:

What are the real customers saying?

The packaging is slick:
"This @21dotco computer came already opened..."
The hardware is reliable:
"...it must have lost power, which caused my SSH keys to become corrupted."
The software is revolutionary:
"...it will be more expensive to pay for your spotify subscription via your electricity bill, but a lot of people don't care."

I want to buy it anyway!

Go ahead. I won't stop you. Oh, and 21 Inc. doesn't accept bitcoins.

Setup with the USB bitcoin miner to the USB powered hub with fan. USB hub must be at lest 1.5 - 2.0 amps. Also the Rpi heatsink and fan. You need this heatsink and cooling fan if you are overclocking the Rpi for maximum mining capability and planning to keep the raspberry pi up 24/7 without burning the core processor. There are also a range of mini miners for hobbyists and individuals interested in getting into mining crypto currencies and this project will show how the Raspberry Pi can be adapted to this purpose. Once a block on the blockchain has been verified then the reward for this processing power and time is a coin of that specific currency. Raspberry Pi in combination with a USB ASIC miner chip makes a good Bitcoin miner (PiMiner) due to its low power usage and ease of configuration. ASIC devices are specialised computing processors specific to the SHA256 algorithm used in Bitcoin hashes. As such, a Raspberry Pi can totally serve as an inexpensive crypto miner. However, the distinction is that the Raspberry Pi can mine, but doesn’t necessarily do so profitably. Mostly, this depends on the specific cryptocurrency, what it’s valued at and how much the Pi can generate each day.
