Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

Zano Newcomers Introduction/FAQ - please read!

Welcome to the Zano Sticky Introduction/FAQ!

https://preview.redd.it/al1gy9t9v9q51.png?width=424&format=png&auto=webp&s=b29a60402d30576a4fd95f592b392fae202026ca
Hopefully any questions you have will be answered by the resources below, but if you have additional questions feel free to ask them in the comments. If you're quite technically-minded, the Zano whitepaper gives a thorough overview of Zano's design and its main features.
So, what is Zano? In brief, Zano is a project started by the original developers of CryptoNote. Coins with market caps totalling well over a billion dollars (Monero, Haven, Loki and countless others) run upon the codebase they created. Zano is a continuation of their efforts to create the "perfect money", and brings a wealth of enhancements to their original CryptoNote code.
Development happens at a lightning pace, as the Github activity shows, but Zano is still very much a work-in-progress. Let's cut right to it:
Here's why you should pay attention to Zano over the next 12-18 months. Quoting from a recent update:
Anton Sokolov has recently joined the Zano team. ... For the last months Anton has been working on theoretical work dedicated to log-size ring signatures. These signatures theoretically allows for a logarithmic relationship between the number of decoys and the size/performance of transactions. This means that we can set mixins at a level from up to 1000, keeping the reasonable size and processing speed of transactions. This will take Zano’s privacy to a whole new level, and we believe this technology will turn out to be groundbreaking!
If successful, this scheme will make Zano the most private, powerful and performant CryptoNote implementation on the planet. Bar none. A quantum leap in privacy with a minimal increase in resource usage. And if there's one team capable of pulling it off, it's this one.

What else makes Zano special?

You mean aside from having "the Godfather of CryptoNote" as the project lead? ;) Actually, the calibre of the developers/researchers at Zano probably is the project's single greatest strength. Drawing on years of experience, they've made careful design choices, optimizing performance with an asynchronous core architecture, and flexibility and extensibility with a modular code structure. This means that the developers are able to build and iterate fast, refining features and adding new ones at a rate that makes bigger and better-funded teams look sluggish at best.
Zano also has some unique features that set it apart from similar projects:
Privacy Firstly, if you're familiar with CryptoNote you won't be surprised that Zano transactions are private. The perfect money is fungible, and therefore must be untraceable. Bitcoin, for the most part, does little to hide your transaction data from unscrupulous observers. With Zano, privacy is the default.
The untraceability and unlinkability of Zano transactions come from its use of ring signatures and stealth addresses. What this means is that no outside observer is able to tell if two transactions were sent to the same address, and for each transaction there is a set of possible senders that make it impossible to determine who the real sender is.
Hybrid PoW-PoS consensus mechanism Zano achieves an optimal level of security by utilizing both Proof of Work and Proof of Stake for consensus. By combining the two systems, it mitigates their individual vulnerabilities (see 51% attack and "nothing at stake" problem). For an attack on Zano to have even a remote chance of success the attacker would have to obtain not only a majority of hashing power, but also a majority of the coins involved in staking. The system and its design considerations are discussed at length in the whitepaper.
Aliases Here's a stealth address: ZxDdULdxC7NRFYhCGdxkcTZoEGQoqvbZqcDHj5a7Gad8Y8wZKAGZZmVCUf9AvSPNMK68L8r8JfAfxP4z1GcFQVCS2Jb9wVzoe. I have a hard enough time remembering my phone number. Fortunately, Zano has an alias system that lets you register an address to a human-readable name. (@orsonj if you want to anonymously buy me a coffee)
Multisig
Multisignature (multisig) refers to requiring multiple keys to authorize a Zano transaction. It has a number of applications, such as dividing up responsibility for a single Zano wallet among multiple parties, or creating backups where loss of a single seed doesn't lead to loss of the wallet.
Multisig and escrow are key components of the planned Decentralized Marketplace (see below), so consideration was given to each of them from the design stages. Thus Zano's multisig, rather than being tagged on at the wallet-level as an afterthought, is part of its its core architecture being incorporated at the protocol level. This base-layer integration means months won't be spent in the future on complicated refactoring efforts in order to integrate multisig into a codebase that wasn't designed for it. Plus, it makes it far easier for third-party developers to include multisig (implemented correctly) in any Zano wallets and applications they create in the future.
(Double Deposit MAD) Escrow
With Zano's escrow service you can create fully customizable p2p contracts that are designed to, once signed by participants, enforce adherence to their conditions in such a way that no trusted third-party escrow agent is required.
https://preview.redd.it/jp4oghyhv9q51.png?width=1762&format=png&auto=webp&s=12a1e76f76f902ed328886283050e416db3838a5
The Particl project, aside from a couple of minor differences, uses an escrow scheme that works the same way, so I've borrowed the term they coined ("Double Deposit MAD Escrow") as I think it describes the scheme perfectly. The system requires participants to make additional deposits, which they will forfeit if there is any attempt to act in a way that breaches the terms of the contract. Full details can be found in the Escrow section of the whitepaper.
The usefulness of multisig and the escrow system may not seem obvious at first, but as mentioned before they'll form the backbone of Zano's Decentralized Marketplace service (described in the next section).

What does the future hold for Zano?

The planned upgrade to Zano's privacy, mentioned at the start, is obviously one of the most exciting things the team is working on, but it's not the only thing.
Zano Roadmap
Decentralized Marketplace
From the beginning, the Zano team's goal has been to create the perfect money. And money can't just be some vehicle for speculative investment, money must be used. To that end, the team have created a set of tools to make it as simple as possible for Zano to be integrated into eCommerce platforms. Zano's API’s and plugins are easy to use, allowing even those with very little coding experience to use them in their E-commerce-related ventures. The culmination of this effort will be a full Decentralized Anonymous Marketplace built on top of the Zano blockchain. Rather than being accessed via the wallet, it will act more as a service - Marketplace as a Service (MAAS) - for anyone who wishes to use it. The inclusion of a simple "snippet" of code into a website is all that's needed to become part a global decentralized, trustless and private E-commerce network.
Atomic Swaps
Just as Zano's marketplace will allow you to transact without needing to trust your counterparty, atomic swaps will let you to easily convert between Zano and other cyryptocurrencies without having to trust a third-party service such as a centralized exchange. On top of that, it will also lead to the way to Zano's inclusion in the many decentralized exchange (DEX) services that have emerged in recent years.

Where can I buy Zano?

Zano's currently listed on the following exchanges:
https://coinmarketcap.com/currencies/zano/markets/
It goes without saying, neither I nor the Zano team work for any of the exchanges or can vouch for their reliability. Use at your own risk and never leave coins on a centralized exchange for longer than necessary. Your keys, your coins!
If you have any old graphics cards lying around(both AMD & NVIDIA), then Zano is also mineable through its unique ProgPowZ algorithm. Here's a guide on how to get started.
Once you have some Zano, you can safely store it in one of the desktop or mobile wallets (available for all major platforms).

How can I support Zano?

Zano has no marketing department, which is why this post has been written by some guy and not the "Chief Growth Engineer @ Zano Enterprises". The hard part is already done: there's a team of world class developers and researchers gathered here. But, at least at the current prices, the team's funds are enough to cover the cost of development and little more. So the job of publicizing the project falls to the community. If you have any experience in community building/growth hacking at another cryptocurrency or open source project, or if you're a Zano holder who would like to ensure the project's long-term success by helping to spread the word, then send me a pm. We need to get organized.
Researchers and developers are also very welcome. Working at the cutting edge of mathematics and cryptography means Zano provides challenging and rewarding work for anyone in those fields. Please contact the project's Community Manager u/Jed_T if you're interested in joining the team.

the year 2020 in Bitcoin Cash so far: a detailed history

the year 2020 in Bitcoin Cash so far: a detailed history
What follows at the bottom is a four page long chronological overview of what happened in BCH in 2020 so far. To make it more digestable and fun to read I start with my narrating of the story.
My attempt was to remain as objective as possible and "let the facts speak for themselve" with everything sourced. I also link to many read.cash articles, the decision of which are the important ones to include is certainly not easy, I count on the rest of the community if I overlooked anything important.

summary & my narrating of the story:
The year started out relatively calm, with cashfusion in "the news" and an older ongoing controversy between Amaury and Roger Ver being worked out. Starting Jan 22nd all debate broke loose with the announcement of “Infrastructure Funding Plan for Bitcoin Cash” by Jiang Zhuoer of BTC.TOP. To illustrate this point 2 days later coinspice ran the title " Roger Ver Praises Vigorous Debate, [...]" and 6 days, less than a week, later Chris Pacia made a read.cash post titled "The 253rd "Thoughts on developer funding" Article" which might have been only a slight exaggeration or he might have been counting. Part of the reason of the tsunami was the lack of worked out details. By the time of Pacia's post a lot had changed: Both BU, Bitcoin Verde and a group of miners had made announcements not to go along with "the plan".
On feb 1st, the second version of the IFP was announced by Jiang Zhuoer in a post “BCH miner donation plan update”. Two weeks later on Feb 15th, the third iteration was announced by Bitcoin ABC which was to be activated by hashrate voting and on the same day Flipstarter was introduced, a sign of the search for alternative solutions. After a few more days and a few more people coming out more against the IFP (including Jonald Fyookball, Mark Lundeberg & Josh Ellithorpe), BCHN was announced on feb 20th with a formal release a week later. Also feb 27th, the DAA was brought back into the conversation by Jonathan Toomim with his " The BCH difficulty adjustment algorithm is broken. Here's how to fix it." video. By early march the IFP was effectively dead with its author Jiang Zhuoer vowing to vote against it. This became clear to everyone when ABC, a day later sudddenly shifted gears towards non-protocol, donation based funding: the IFP was dead. End march ABCs 2020 Business Plan was announced as a way to raise $3.3 million. Mid april to mid may was the high time for voluntary funding with four node implementations and General Protocols, a BCH DeFi Startup successfully raising funds.
By May 15th, the 6th HF network upgrade things had pretty much cooled down. The upgraded included nothing controversial and even saw an unexpected doubling in the unconfirmed transaction chain. June 15th a month later things started to heat up again with the BCHN announcement to remove the "poison pill" or "automatic replay protection". 8th Jul Jonathan Toomim posted "BCH protocol upgrade proposal: Use ASERT as the new DAA" which promised the solution to the long dragging DAA problem. Jul 23th however an unexpected twist occurred when Amaury Séchet posted "Announcing the Grasberg DAA" an incompatible, alternative solution. This, again, sparked a ton of debate and discussion. Grasberg lasted just two weeks from Jul 23th to Aug 6th when ABC announced its plans for the november 2020 upgrade but it had successfully united the opposition in the meanwhile. ABCs plan for november included dropping grasberg in favour of aserti3–2d and introducing IFPv4. Now we're here August 8th, the IFP which was declared dead after just over a month (Jan 22-Mar 5) is now back in full force. The rest of the history is still being written but if p2p electronic cash is to succeed in any big regard it's very thinkable that these events will get into history books.

ARK. Here's what's it's all about, what's been going on, and what's coming. [Explain Like I'm Busy]

Dude, it said explain like I'm busy I'm not going to read all this

No problem. Check out these hand-picked relevant ARK Crypto Podcast episodes. Learn while you listen, drive to work or home, cook a steak, give your dog a bath, etc.
If you have decided to read all this, thanks, keep reading for a concise breakdown!

So what's the current big thing going on with ARK right NOW?

ARK.io has recently announced on both its blog and its Twitter that ARK Core v2.6 is coming to Mainnet February 11th. The iteration of 2.6 may sound anticlimactic, but it's far from that. Core v2.6 is the biggest upgrade to date- even bigger than the total Core overhaul performed for v2.0, deployed late 2018.
The new version brings new transaction types to the ARK Public Network, including types that will play a role in creating an ecosystem of linked chains. This ecosystem of linked chains will have the ARK Public Network in the center of the action, storing chain details and allowing for chain discovery.
These new transaction types include:
Multipayments — sending to multiple ARK addresses, while just initiating one transaction, saves time and cost
Multisignatures — you can now get all of the benefits of multisignatures where more than one user can propose or spend funds depending on the predefined terms (eg. 2 out of 3 users needed to successfully send tokens, vote, …)
IPFS — register IPFS compliant hashes on the ARK blockchain within Desktop Wallet.
Business & Bridgechain registrations — you can now register your business and bridgechain on the blockchain and soon, you will be able to get verified via our Marketplace to get access to some exciting new features.
Delegate resignation — delegates who don’t want to be voted for anymore can now opt-out of this by simply initiating delegate resignation.
Additionally, the Core v2.6 improves security against double-spend attacks by implementing nonces. Also, massive enhancements were made to the GTI or Generic Transaction Interface, a critical tool for developers who wish to develop decentralized applications.

What is ARK's unique approach to current issues plaguing the blockchain industry?

ARK empowers everyone, regardless of their aim or technical background, to quickly and easily leverage blockchain technology. In the current hype-driven blockchain landscape, ARK acts as a beacon for individuals, groups, and enterprises seeking to apply blockchain technology to both reach their individual goals and affect change in their local community. ARK’s uniquely simple technology stack allows almost anyone to create and deploy standalone blockchains for any use case with an intuitive graphical user interface and experience. These newly created blockchains also known as bridgechains will have the ability to interoperate through ARK SmartBridge Technology. ARK is also reinventing smart contracts with ARK Logic, a collection of tools including custom transaction types, templates, and plugins. ARK Logic brings security, adaptability, and scalability to decentralized computing workflows. Most importantly, the ARK Ecosystem fosters a growing international community of developers, node operators, blockchains, businesses, and enthusiasts who collectively breathe life into this disruptive technology. Get into the interactive whitepaper here.

Tell me about the ARK Public Network

Ok, no problem. Since coming online on March 21, 2017, the APN has operated as a P2P cryptocurrency with fast block times of 8 seconds and low dynamic fees (near a penny and somewhat novel for a DPoS blockchain). However, the end goal of the APN far exceeds that of just a cryptocurrency that is faster and cheaper to use than Bitcoin. I'll explain further in a minute.
The network, as mentioned, is set up as Delegated Proof-of-Stake. This means forging delegates are deemed worthy to secure the chain and add blocks to it by the holders of the ARK token, which vote for delegates using their ARK as vote weight. ARK remains in users' control at all times, and the top 51 delegates in vote weight enter forging status. The network awards each delegate 2 ARK per block (~12,705 ARK/mo) for services rendered. This continues ad infinitum resulting in a declining inflation rate each year (relative to total supply). When users add or remove ARK from a voting wallet address, vote weight adjusts automatically and they don't need to vote again. Voting continues even if user's wallet is offline.
The main uses of ARK as the cryptoasset of the ARK Public Network besides being a P2P cryptocurrency include:

Is team good?

Yes, team good. Team very good. General sentiment among ARK team members is that ARK is a dream project to work on, and this motivates them to do great work on a consistent basis as the ARK technology stack progresses. Very recently, ARK hired an additional half dozen people in various departments, including marketing department. This brings ARK team total to over three dozen experts. The ARK business entity is also well funded with around 10 years of budget. The ARK business entity spends funds in a very sensible manner compared to some other projects who spend with insufficient foresight or discretion.
Members of the board are thoughtful and deliberate, and the CEO FX Thoorens has been hard at work putting a spotlight on ARK, showing an 'intermeshing' of ARK with the global regulatory landscape in regards to crypto. Recently, ARK became a founding member of ADAN, a professional association based in France created to help structure and develop the digital assets industry. Other members include Consensys France and Ledger. ADAN will consult with public authorities, industry leaders and private bodies to promote the use of digital assets and all activities in this sector. This includes exchange platforms, brokers, hardware, protocols, decentralized applications and blockchain technology platforms. Hear FX Thoorens talk more about this in this podcast episode.
The ARK business entity is located in France, but the ARK team is distributed across 10+ countries and multiple continents.

What's going to happen?

Cool stuff. Organizations and open source projects have been stumbling across ARK and really like what they see. Multiple projects are working with ARK technology and are at various stages of development, but since you're busy, I'll highlight the project nOS which recently launched their public testnet and uses ARK technology for their blockchain. nOS also has great things to say about ARK that you can hear in this podcast episode or watch in this video.
We believe that as more businesses, organizations, and open source projects start looking around for blockchain solutions, they will also enjoy ARK's simplicity, flexibility, and feature set. Our powerful technology stack is backed up by a recently upgraded documentation hub for developers.
The product we have that makes it very easy for projects to join the ARK Ecosystem is called the ARK Deployer, which you can learn about in this two minute video. It allows developers from all walks of life to create, customize and launch a standalone blockchain in three simple steps. In the near future, what's going to happen is a big improvement to the Deployer. The ARK Deployer will get an upgraded and more powerful user interface that also facilitates chain management post-launch, as well as interface directly with cloud providers like Digital Ocean to launch genesis node and peers in background. This would allow for a massive leap forward in our vision of 'Point. Click. Blockchain.'
ARK.io is also working on a Marketplace for developers, where custom plugins and tools developed by both ARK.io as well as third parties can be acquired for assembling blockchains much easier. Imagine a wordpress-type environment where you can create a super-powerful and customized blockchain by connecting Legos together. In the same way that early World Wide Web needed WordPress/Squarespace style tools to bring the technology to every business or organization, we believe that this need will be out there for blockchain technology as this new decade progresses.
There is more cool stuff that is going to happen, but I'll wrap it up there for now.

After reading all this stuff, what is it you want me to do?

Well, not make any financial decisions, because that is not the purpose of this information. However, as a developer, there's a lot of interesting things you should know and may want to consider doing. The ARK technology stack uses TypeScript and other JS-style frameworks, so if you know those, you should get excited.
Here's some additional less 'developery' stuff you can do:
Thanks for coming along for the ride of this post. ARK has been out here, it's out here, and it's going to continue to be out here, doing its part to make sure everybody knows that blockchains are, in fact, a thing.

The REAL biggest issue facing Bitcoin Cash: we are under attack and many don't realize it

Many in our community are warning us that we are in danger because we are letting ourselves be defined by BTC, and too negative in how we interact online.
Let me be crystal clear, they are WRONG.
First, watch this video. It's an interview with a KGB defector. It was filmed over 30 years ago, but sounds like it is talking about current events.
What you must understand is that the BCH community is under attack. We, whether we know it or not, are at war. If you don't perceive this as reality, you are nothing more than a useful idiot. It's not just a war, it's an asymmetric war, and the odds aren't in our favor.
At best, BTC and decentralized cryptocurrencies are under attack by bank funded VC's who are trying to rent seek on BTC while keeping it dominant.
At worst, and most likely, BTC and decentralized cryptocurrencies are under attack by state actors, with companies that profit from the attack tagging merrily along.
In the video, Yuri talks about four stages when the KGB would attempt to attack a community/country/adversary during a cold war. It wasn't James Bond and espionage, it was almost all social manipulation. Here are the four stages:
1 Demoralize.
This process takes years. For countries it takes an entire generation, 15-20 years. For crypto, it happened much faster, because they started very early, when culture was still being formed in 2011. With BTC it happened with the "contentious blocksize debate". Developers were installed by blockstream and other companies, spokespeople came out of the woodwork blocking scaling, and progress on BTC was halted. The narrative was controlled by censorship and banning, and figureheads that wanted to scale Bitcoin had their reputations attacked and ruined. I have never been so frustrated and demoralized in my life as I was from 2014 to 2017. I know many of you reading this know what I'm talking about.
2 Destabilize.
This happened with BTC with the SegWit 2x fork, where they double crossed with the 2x increase.
3 Crisis.
This was the fork. The few people who had the tenacity to put up with all of the bullshit in 1 and 2 were forced to fork off into a much smaller community, the refuge called Bitcoin Cash.
4 Normalization.
This is when the adversary takes control. This has happened with BTC. The blocksize will never be increased, and the only scaling that will ever happen will be through bank-like hubs, controlled by the same authorities we have in place today. Anyone that disagrees is cast out and must find a different community. BTC's dominance is cemented because huge financial giants pump the price, and attack alternatives viciously.
But wait... that's not the only attack. BCH was subsequently attacked again!
1 Demoralize.
CSW (the guy who ruined Gavin's reputation, mind you) wormed his way into the community over around a year. Backed by an online gambling billionaire who was on the FBI's most wanted list (hmmmm) and unknown funders behind that front powering "nChain".
2 Destabilize.
nChain and CSW introduce changes that force a hard fork in BCH only days before the scheduled upgrade date, months after the code for the upgrade was agreed to by all parties and frozen.
3 Crisis.
The fork. Planted agents and useful idiots like Ryan Charles leave the project, supporting BSV. Our community is fractured AGAIN. BCH itself is suspected to be 51% attacked, but only through a shift in hash power and the 10 block rollback emergency change, this attack is mitigated.
4 Normalization.
Projects and developers (both agents and useful idiots) left the BCH ecosystem, and now support the fully controlled BSV chain, leaving BCH weaker and demoralized.
This process, demoralize, destabilize, crisis, normalization will be repeated over and over and over, forever, as long as the existing financial institutions and/or state powers deem cryptocurrency a threat.
The Soviets used to murder useful idiots during normalization, when they realized they had been duped. I don't think we've had much murder, thankfully, but if state actors are involved, don't rule it out.
If we are naive, ignore the fact that we are under attack by a larger adversary who will use any tactic to win, and only talk about the positives of BCH, that message WILL be drown out by 10x more Bcash Jihan Roger centralized BS. Our adversaries have more resources, people, and are laser focused on their attack.
It's unfortunate, but we MUST point out common sense, and educate newcomers over and over about the history of the BTC attack, the BSV attack, and any future attacks that can and will be made against BCH.
If we don't, BCH will be drown out by the psychological operation, and become a failed experiment.
It's going to be a long, hard road.

IOTA and Tangle discussion/info, scam or not?

In the past weeks I heard a lot pros and cons about IOTA, many of them I believe were not true (I'll explain better). I would like to start a serious discussion about IOTA and help people to get into it. Before that I'll contribute with what I know, most things that I will say will have a source link providing some base content.
 
The pros and cons that I heard a lot is listed below, I'll discuss the items marked with *.
Pros
Cons
 

Scalability

Many users claim that the network infinitely scales, that with more transactions on the network the faster it gets. This is not entirely true, that's why we are seeing the network getting congested (pending transactions) at the moment (12/2017).
The network is composed by full-nodes (stores all transactions), each full-node is capable of sending transactions direct to the tangle. An arbitrary user can set a light-node (do not store all transactions, therefore a reduced size), but as it does not stores all transactions and can't decide if there are conflicting transactions (and other stuff) it needs to connect to a full-node (bitifinex node for example) and then request for the full-node to send a transaction to the tangle. The full-node acts like a bridge for a light-node user, the quantity of transactions at the same time that a full-node can push to the tangle is limited by its brandwidth.
What happens at the moment is that there are few full-nodes, but more important than that is: the majority of users are connected to the same full-node basically. The full-node which is being used can't handle all the requested transactions by the light-nodes because of its brandwidth. If you are a light-node user and is experiencing slow transactions you need to manually select other node to get a better performance. Also, you need to verify that the minimum weight magnitude (difficulty of the Hashcash Proof of Work) is set to 14 at least.
The network seems to be fine and it scales, but the steps an user has to make/know are not friendly-user at all. It's necessary to understand that the technology envolved is relative new and still in early development. Do not buy iota if you haven't read about the technology, there is a high chance of you losing your tokens because of various reasons and it will be your own fault. You can learn more about how IOTA works here.
There are some upcoming solutions that will bring the user-experience to a new level, The UCL Wallet (expected to be released at this month, will talk about that soon and how it will help the network) and the Nelson CarrIOTA (this week) besides the official implementations to come in december.
 

Centralization

We all know that currently (2017) IOTA depends on the coordinator because the network is still in its infancy and because of that it is considered centralized by the majority of users.
The coordinator are several full-nodes scattered across the world run by the IOTA foundation. It creates periodic Milestones (zero value transactions which reference valid transactions) which are validated by the entire network. The coordinator sets the general direction for the tangle growth. Every node verifies that the coordinator is not breaking consensus rules by creating iotas out of thin air or approving double-spendings, nodes only tells other nodes about transactions that are valid, if the Coordinator starts issuing bad Milestones, nodes will reject them.
The coordinator is optional since summer 2017, you can choose not implement it in your full-node, any talented programmer could replace Coo logic in IRI with Random Walk Monte Carlo logic and go without its milestones right now. A new kind of distributed coordinator is about to come and then, for the last, its completely removal. You can read more about the coordinator here and here.

Mining-Blockchain-based Cryptocurrencies

These are blockchain-based cryptocurrencies (Bitcoin) that has miners to guarantee its security. Satoshi Nakamoto states several times in the Bitcoin whitepaper that "The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes". We can see in Blockchain.info that nowadays half of the total hashpower in Bitcoin is controlled by 3 companies (maybe only 1 in the future?). Users must trust that these companies will behave honestly and will not use its 50%> hashpower to attack the network eventually. With all that said it's reasonable to consider the IOTA network more decentralized (even with the coordinator) than any mining-blockchain-based cryptocurrency
You can see a comparison between DAG cryptocurrencies here
 

IOTA partnerships

Some partnerships of IOTA foundation with big companies were well known even when they were not officialy published. Some few examples of confirmed partnerships are listed below, others cofirmed partnerships can be seem in the link Partnerships with big companies at the pros section.
So what's up with all alarming in social media about IOTA Foundation faking partnerships with big companies like Microsoft and Cisco?
At Nov. 28th IOTA Foundation announced the Data Marketplace with 30+ companies participating. Basically it's a place for any entity sell data (huge applications, therefore many companies interested), at time of writing (11/12/2017) there is no API for common users, only companies in touch with IOTA Foundation can test it.
A quote from Omkar Naik (Microsoft worker) depicted on the Data Marketplace blog post gave an idea that Microsoft was in a direct partnership with IOTA. Several news websites started writing headlines "Microsoft and IOTA launches" (The same news site claimed latter that IOTA lied about partnership with Microsoft) when instead Microsoft was just one of the many participants of the Data Marketplace. Even though it's not a direct partnership, IOTA and Microsoft are in close touch as seen in IOTA Microsoft and Bosch meetup december 12th, Microsoft IOTA meetup in Paris 14th and Microsoft Azure adds 5 new Blockchain partners (may 2016). If you join the IOTA Slack channel you'll find out that there are many others big companies in close touch with IOTA like BMW, Tesla and other companies. This means that right now there are devs of IOTA working directly with scientists of these companies to help them integrate IOTA on their developments even though there is no direct partnership published, I'll talk more about the use cases soon.
We are excited to partner with IOTA foundation and proud to be associated with its new data marketplace initiative... - Omkar Naik
 

IOTA's use cases

Every cryptocurrency is capable of being a way to exchange goods, you pay for something using the coin token and receive the product. Some of them are more popular or have faster transactions or anonymity while others offers better scalablity or user-friendness. But none of them (except IOTA) are capable of transactioning information with no costs (fee-less transactions), in an securely form (MAM) and being sure that the network will not be harmed when it gets more adopted (scales). These characteristics open the gates for several real world applications, you probably might have heard of Big Data and how data is so important nowadays.
Data sets grow rapidly - in part because they are increasingly gathered by cheap and numerous information-sensing Internet of things devices such as mobile devices, aerial (remote sensing), software logs, cameras, microphones, radio-frequency identification (RFID) readers and wireless sensor networks.
 
It’s just the beginning of the data period. Data is going to be so important for human life in the future. So we are now just starting. We are a big data company, but compared to tomorrow, we are nothing. - Jack Ma (Alibaba)
There are enormous quantities of wasted data, often over 99% is lost to the void, that could potentially contain extremely valuable information if allowed to flow freely in data streams that create an open and decentralized data lake that is accessible to any compensating party. Some of the biggest corporations of the world are purely digital like Google, Facebook and Amazon. Data/information market will be huge in the future and that's why there so many companies interested in what IOTA can offer.
There are several real world use cases being developed at the moment, many of them if successful will revolutionize the world. You can check below a list of some of them.
Extra
These are just few examples, there are a lot more ongoing and to explore.
 

IOTA Wallet (v2.5.4 below)

For those who have read a lot about IOTA and know how it works the wallet is fine, but that's not the case for most users. Issues an user might face if decide to use the current wallet:
Problems that could be easily avoided with a better understand of the network/wallet or with a better wallet that could handle these issues. As I explained before, some problems during the "congestion" of the network could be simply resolved if stuff were more user-friendly, this causes many users storing their iotas on exchanges which is not safe either.
The upcoming (dec 2017) UCL Wallet will solve most of these problems. It will switch between nodes automatically and auto-reattach transactions for example (besides other things). You can have full a overview of it here and here. Also, the upcoming Nelson CarrIOTA will help on automatic peer discovery for users setup their nodes more easily.
 

IOTA Vulnerability issue

On sept 7th 2017 a team from MIT reported a cryptographic issue on the hash function Curl. You can see the full response of IOTA members below.
Funds were never in danger as such scenarios depicted on the Neha's blogpost were not pratically possible and the arguments used on the blogpost had'nt fundamentals, all the history you can check by yourself on the responses. Later it was discovered that the whole Neha Narula's team were envolved in other concurrent cryptocurrency projects
Currently IOTA uses the relatively hardware intensive NIST standard SHA-3/Keccak for crucial operations for maximal security. Curl is continuously being audited by more cryptographers and security experts. Recenlty IOTA Foundation hired Cybercrypt, the world leading lightweight cryptography and security company from Denmark to take the Curl cryptography to its next maturation phase.
 
It took me a couple of days to gather the informations presented, I wanted it to make easier for people who want to get into it. It might probably have some mistakes so please correct me if I said something wrong. Here are some useful links for the community.
This is my IOTA donation address, in case someone wants to donate I will be very thankful. I truly believe in this project's potential.
I9YGQVMWDYZBLHGKMTLBTAFBIQHGLYGSAGLJEZIV9OKWZSHIYRDSDPQQLTIEQEUSYZWUGGFHGQJLVYKOBWAYPTTGCX
 
This is a donation address, if you want to do the same you might pay attention to some important details:
  • Create a seed for only donation purposes.
  • Generate a address and publish it for everyone.
  • If you spend any iota you must attach a new address to the tangle and refresh your donation address published before to everyone.
  • If someone sends iota to your previous donation address after you have spent from it you will probably lose the funds that were sent to that specific address.
  • You can visualize how addresses work in IOTA here and here.
This happens because IOTA uses Winternitz one-time signature to become quantum resistent. Every time you spend iota from a address, part of the private key of that specific address is revealed. This makes easier for attackers to steal that address balance. Attackers can search if an address has been reused on the tangle explorer and try to brute force the private key since they already know part of it.

Abstract

The early smart contracts of Era Swap Ecosystem like TimeAlly, Newly Released Tokens, Assurance, BetDeEx of Era Swap Ecosystem, are deployed on Ethereum mainnet. These smart contracts are finance-oriented (DeFi), i.e. most of the transactions are about spending or earning of Era Swap tokens which made paying the gas fees in Ether somewhat intuitive to the user (withdrawal charges in bank, paying tax while purchasing burgers) but transactions that are not token oriented like adding a nominee or appointee voting also needs Ether to be charged. As more Era Swap Token Utility platform ideas kept appending to the Era Swap Main Whitepaper, more non-financial transaction situations arise like updating status, sending a message, resolving a dispute and so on. Paying extensively for such actions all day and waiting for the transaction to be included in a block and then waiting for enough block confirmations due to potential chain re-organizations is counter-intuitive to existing free solutions like Facebook, Gmail. This is the main barrier that is stopping Web 3.0 from coming to the mainstream.
As alternatives to Ethereum, there are few other smart contract development platforms that propose their own separate blockchain that features for higher transaction throughput, but they compromise on decentralization for improving transaction speeds. Moreover, the ecosystem tools are most advancing in Ethereum than any other platform due to the massive developer community.
With Era Swap Network, the team aims to achieve scalability, speed and low-cost transactions for Era Swap Ecosystem (which is currently not feasible on Ethereum mainnet), without compromising much on trustless asset security for Era Swap Community users.

Introduction to Era Swap Network

Era Swap Network (ESN) aims to solve the above-mentioned problems faced by Era Swap Ecosystem users by building a side-blockchain on top of Ethereum blockchain using the Plasma Framework.
Era Swap Network leverages the Decentralisation and Security of Ethereum and the Scalability achieved in the side-chain, this solves the distributed blockchain trilema. In most of the other blockchains, blocks are a collection of transactions and all the transactions in one block are mined by a miner in one step. Era Swap Network will consist of Bunches of Blocks of Era Swap Ecosystem Transactions.

Decentralization

Layer 2


Scalable and Secure

A miner mines all the blocks in a bunch consequently and will commit the bunch-root to the ESN Plasma Smart Contract on Ethereum mainnet.

Development Overview
Initially, we will start with a simple Proof-of-Authority (PoA) based consensus of EVM to start the development and testing of Era Swap Ecosystem Smart Contracts as quickly as possible on the test-net. We will call this as an alpha-release of ESN test-net and only internal developers will work with this for developing smart contracts for Era Swap Ecosystem. User’s funds in a Plasma implementation with a simple consensus like PoA are still secured as already committed bunch-roots cannot be reversed.
Eventually, we want to arrive on a more control-decentralized consensus algorithm like Proof-of-Stake (PoS) probably, so that even if the chain operator shuts down their services, a single Era Swap Ecosystem user somewhere in the world can keep the ecosystem alive by running software on their system and similarly more people can join to decentralize the control further. In this PoS version, we will modify the Parity Ethereum client in such a way, that at least 50% of transaction fees collected will go to the Luck Pool of NRT Smart Contract on Ethereum mainnet and rest can be kept by miner of the blocks/bunch of blocks if they wish. After achieving such an implementation, we will release this as a beta version to the community for testing the software on their computers with Kovan ERC20 Era Swaps (Ethereum test-net).

Era Swap Decentralised Ecosystem
Following platforms are to be integrated:
  1. Era Swap Token Contract (adapted ERC20 on Ethereum) The original asset will lie on Ethereum to avoid loss due to any kind of failure in ESN.
  2. Plasma Manager Contract (on Ethereum) To store ESN bunch headers on Ethereum.
  3. Reverse Plasma Manager Contract (on ESN) Bridge to convert ES to ES native and ES native to ES. User deposits ES on Mainnet Plasma, gives proof on ESN and gets ES native credited to their account in a decentralised way.
  4. NRT Manager Contract (on Ethereum or on ESN) If it is possible to send ES from an ESN contract to luck pool of NRT Manager Contract on Ethereum, then it’s ok otherwise, NRT Manager will need to be deployed on ESN for ability to add ES to luck pool.
  5. Era Swap Wallet (React Native App for managing ESs and ES natives) Secure wallet to store multiple private keys in it, mainly for managing ES and ES native, sending ES or ES native, also for quick and easy BuzCafe payments.
  6. TimeAlly (on Ethereum or on ESN) On whichever chain NRT Manager is deployed, TimeAlly would be deployed on the same chain.
  7. Assurance (on Ethereum or on ESN) On whichever chain NRT Manager is deployed, TimeAlly would be deployed on the same chain.
  8. DaySwappers (on ESN) KYC manager for platform. For easily distributing rewards to tree referees.
  9. TimeSwappers (on ESN) Freelance market place with decentralised dispute management.
  10. SwappersWall (on ESN) Decentralised social networking with power tokens.
  11. BuzCafe (on ESN) Listing of shops and finding shops easily and quick payment.
  12. BetDeEx (on ESN) Decentralised Prediction proposals, prediction and results.
  13. DateSwappers (on ESN) Meeting ensured using cryptography.
  14. ComputeEx (on Ethereum / centralised way) Exchange assets.
  15. Era Swap Academy (on ESN / centralised way) Learn. Loop. Leap. How to implement ES Academy is not clear. One idea is if content is constantly being modified, then subscription expired people will only have the hash of old content while new content hash is only available to people who have done Dayswapper KYC and paid for the course. Dayswapper KYC is required because this way people won’t share their private keys to someone else.
  16. Value of Farmers (tbd) The exchange of farming commodities produced by farmers in VoF can be deposited to warehouses where the depositors will get ERC721 equivalent tokens for their commodities (based on unique tagging).
  17. DeGameStation (on ESN) Decentralised Gaming Station. Games in which players take turns can be written in Smart Contract. Games like Chess, Poker, 3 Patti can be developed. Users can come to DeGameStation and join an open game or start a new game and wait for other players to join.

Alpha-release Development Plan
  1. Deploying Parity Node customized according to Era Swap Whitepaper with PoA consensus.
  2. Setting up Plasma Smart Contracts.
  3. Creating a bridge for ERC20 Swap from Ethereum test-net to ESN alpha test-net.

Alpha Version
Era Swap Network Version 1 : Specification
The Version 1 release of ESN plans to fulfill the requirements for political decentralisation and transparency in dApps of Era Swap Ecosystem using Blockchain Technology. After acquiring sufficient number of users, a version 2 construction of ESN will be feasible to enable administrative decentralization, such that the Era Swap Ecosystem will be run and managed by the Era Swap Community and will no longer require the operator to support for it's functioning.
Era Swap Network (ESN) Version 1 will be a separate EVM-compatible sidechain attached to Ethereum blockchain as it’s parent chain. ESN will achieve security through Plasma Framework along with Proof-of-Authority consensus for faster finality. The idea behind plasma framework is to avoid high transaction fees and high transaction confirmation times on Ethereum mainnet by instead doing all the ecosystem transactions off-chain and only post a small information to an Ethereum Smart Contract which would represent hash of plenty of ecosystem transactions. Also, to feature movement of Era Swap Tokens from Ethereum blockchain to ESN using cryptographic proof, reverse plasma of Ethereum on ESN will be implemented.
Also, submitting hash of each ESN blocks to ESN Plasma Smart Contract on Ethereum would force ESN to have a block time equal to or more than Ethereum’s 15 second time as well as it would be very much costly for operator to post lot of hashes to an Ethereum Smart Contract. This is why, merkle root of hashes of bunch of blocks would instead be submitted to ESN Plasma Smart Contact on Ethereum.
Actors involved in the ESN:
  1. Block Producer Nodes Lesser the number of nodes, quicker is the block propagation between block producers which can help quick ecosystem transactions. We find that 7 block producers hosted on different could hosting companies and locations reduces the risk of single point of failure of Era Swap Ecosystem and facilitates 100% uptime of dApps. Block Producer Nodes will also be responsible to post the small information to the Blockchain.
  2. Block Listener Nodes Rest of the nodes will be Block Listeners which will sync new blocks produced by the block producer nodes. Plenty of public block listener nodes would be setup in various regions around the world for shorter ping time to the users of Era Swap Ecosystem. Users would submit their Era Swap Ecosystem transactions to one of these public nodes, which would relay them to rest of the Era Swap Network eventually to the block producer nodes which would finalize a new block including the user transaction.
  3. Bunch Committers This will be an instance in the block producers which will watch for new blocks confirmed on ESN and will calculate bunch merkle roots and will submit it to ESN Plasma Smart Contract. This instance will also post hash of new Ethereum blocks to ESN (after about 10 confirmations) for moving assets between both the blockchain.
  4. Users These will be integrating with dApps which would be connected to some public ESN nodes or they can install a block listner node themselves. They can sign and send transactions to the node which they are connected to and then that node will relay their transactions to block producer nodes who would finalise a block including their transaction.

Bunch Structure

A Bunch Structure in Smart Contract will consist of the following:
• Start Block Number: It is the number of first ESN block in the bunch.
• Bunch Depth: It is Merkle Tree depth of blocks in the bunch. For e.g. If bunch depth is 3, there would be 8 blocks in the bunch and if bunch depth is 10, there would be 1024 blocks in the bunch. Bunch depth of Bunches on ESN Plasma Contract is designed to be variable. During the initial phases of ESN, it would be high, for e.g. 15, to avoid ether expenditure and would be decreased in due course of time.
• Transactions Mega Root: This value is the merkle root of all the transaction roots in the bunch. This is used by Smart Contract to verify that a transaction was sent on the chain.
• Receipts Mega Root: This value is the merkle root of all the receipt roots in the bunch. This is used to verify that the transaction execution was successful.
• Timestamp: This value is the time when the bunch proposal was submitted to the smart contract. After submission, there is a challenge period before it is finalised.

Converting ES-ERC20 to ERC-NA and BACK

On Ethereum Blockchain, the first class cryptocurrency is ETH and rest other tokens managed by smart contracts are second class. On ESN, there is an advancement to have Era Swaps as the first class cryptocurrency. This cryptocurrency will feature better user experience and to differentiate it from the classic ERC20 Era Swaps, it will be called as Era Swap Natives (ES-Na). According to the Era Swap Whitepaper, maximum 9.1 Million ES will exist which will be slowly released in circulation every month.
Era Swaps will exist as ES-ERC20 as well as in form of ES-Na. One of these can be exchanged for the other at 1:1 ratio.
Following is how user will convert ES-ERC20 to ES-Na:
  1. User will give allowance to a Deposit Smart Contract, and following that call deposit method to deposit tokens to the contract.
  2. On transaction confirmation, user will paste the transaction hash on a portal which will generate a Proof of Deposit string for the user. This string is generated by fetching all the transactions in the Ethereum Block and generating a Transaction Patricia Merkle Proof to prove that user’s transaction was indeed included in the block and the Receipts Patricia Merkle Proof to confirm that the user’s transaction was successful.
  3. Using the same portal, user will submit the generated proofs to a Smart Contract on ESN, which would release funds to user. Though, user will have to wait for the Etheruem block roots to be posted to ESN after waiting for confirmations which would take about 3 minutes. Once, it’s done user’s proofs will be accepted and will receive exact amount of ES- Na on ESN.
Following is how user will convert ES-Na to ES-ERC20:
  1. ES-Na being first class cryptocurrency, user will simply send ES-Na to a contract.
  2. User will paste the transaction hash on a portal which will generate a Proof of Deposit for the user. Again ES-Na being first class cryptocurrency, Transaction Patricia Merkle Proof is enough to prove that user’s transaction was indeed included in the block. Another thing which will be generated is the block inclusion proof in the bunch.
  3. User will have to wait for the bunch confirmation to the Plasma Smart Contract and once it’s done, user can send the proof to the Plasma Smart Contract to receive ES-ERC20.

HARD Exit

Since the blocks are produced and transactions are validated by few block producers, it exposes a possibility for fraud by controlling the block producer nodes. Because ESN is based on the Plasma Model, when failure of sidechain occurs or the chain halts, users can hard exit their funds directly from the Plasma Smart Contract on Ethereum by giving a Proof of Holdings.

HOld ES Tokens Swapping with New ES Tokens

The old ES Tokens will be valueless as those tokens will not be accepted in ESN because of NRT (New Released Tokens) and TimeAlly contracts on mainnet which is causing high gas to users, hence reducing interactions. Also, there was an event of theft of Era Swap Tokens and after consensus from majority of holders of Era Swap Tokens; it was decided to create a new contract to reverse the theft to secure the value of Era Swap Tokens of the community. Below is the strategy for swapping tokens:
TimeAlly and TSGAP: Majority of Era Swap Community have participated in TimeAlly Smart Contract in which their tokens are locked for certain period of time until which they cannot move them. Such holders will automatically receive TimeAlly staking of specific durations from the operator during initialization of ESN.
Liquid Tokens: Holders of Liquid Era Swap Tokens have to transfer the old tokens to a specified Ethereum wallet address managed by team. Following that, team will audit the token source of the holder (to eliminate exchange of stolen tokens) and send new tokens back to the wallet address.

Post-Genesis Tokens Return Program

Primary asset holding of Era Swap tokens will exist on Ethereum blockchain as an ERC20 compatible standard due to the highly decentralised nature of the blockchain. Similar to how users deposit tokens to an cryptocurrency exchange for trading and then withdraw the tokens back, users will deposit tokens to ESN Contract to enter Era Swap Ecosystem and they can withdraw it back from ESN Contract for exiting from ecosystem network. The design of the token system will be such that, it will be compatible with the future shift (modification or migration of ESN version 1) to ESN version 2, in which an entirely new blockchain setup might be required.
To manage liquidity, following genesis structure will be followed:

Holder ES-ERC20 ES-Na
Team Wallet 1.17 billion (Circulating Supply) 0
Locked in Smart Contract 7.93 billion (pending NRT releases) 9.1 billion
Though it looks like there are 9.1 * 2 = 18.2 Billion ES, but the cryptographic design secures that at any point in time at least a total of 9.1 billion ES (ES-ERC20 + ES-Na) will be locked. To unlock ES-Na on ESN, an equal amount of ES-ERC20 has to be locked on Ethereum and vice-versa.
9.1 billion ES-ERC20 will be issued by ERC20 smart contract on Ethereum Blockchain, out of which the entire circulating supply (including liquid and TimeAlly holdings) of old ES will be received to a team wallet.
TimeAlly holdings of all users will be converted to ES-Na and distributed on ESN TimeAlly Smart Contract by team to the TimeAlly holders on their same wallet address.
Liquid user holdings will be sent back to the users to the wallet address from which they send back old ES tokens (because some old ES are deposited on exchange wallet address).
ES-Na will be issued in the genesis block to an ESN Manager Smart Contract address. It will manage all the deposits and withdrawals as well as NRT releases.

Attack Vectors


Following are identified risks to be taken care of during the development of ESN:
Network Spamming: Attackers can purchase ES from the exchange and make a lot of transactions between two accounts. This is solved by involving gas fees. A setting of 200 nanoES minimum gas price will be set, which can be changed as per convenience.
DDoS: Attackers can query public nodes for computationally heavy output data. This will overload the public node with requests and genuine requests might get delayed. Block producers RPC is private, so they will continue to produce blocks. To manage user’s denial of service, the provider in dApps needs to be designed in such a way such that many public nodes will be queried simple information (let’s say latest block number) and the one which response quickly to user will be selected.
AWS is down: To minimize this issue due to cloud providers down, there will be enough nodes on multiple cloud providers to ensure at least one block producer is alive.
User deposit double spending: User deposits ES on Ethereum, gets ES-Na on ESN. Then the issue happens that there are re-org on ETH mainnet and the user’s transaction is reversed. Since ETH is not a fixed chain and as per PoW 51% attack can change the blocks. As Ethereum is now enough mature and by statistics forked blocks are at most of height 2. So it is safe to consider 15 confirmations.
Exit Game while smooth functioning: User starts a hard exit directly from Plasma Smart Contract on Ethereum, then spends his funds from the plasma chain too. To counter this, the exit game will be disabled, only when ESN halts, i.e. fails to submit block header within the time the exit game starts. This is because it is difficult to mark user’s funds as spent on ESN.
Vulnerability in Ecosystem Smart Contracts: Using traditional methods to deploy smart contracts results in a situation where if a bug is found later, it is not possible to change the code. Using a proxy construction for every ecosystem smart contract solves this problem, and changing a proxy can be given to a small committee in which 66% of votes are required, this is to prevent a malicious change of code due to compromising of a single account or similar scenario.
ChainID replay attacks: Using old and traditional ways to interact with dApps can cause loss to users, hence every dApp will be audited for the same.

Conclusion

Era Swap Network is an EVM-compatible sidechain attached to the Ethereum blockchain through Plasma Framework. This allows off-chain processing of Era Swap Ecosystem transactions and posting only the hash of the bunch to Ethereum. This greatly reduces the high network fee and confirmation time issues faced by the current Era Swap Ecosystem DApps deployed on Ethereum. Also, having a separate EVM-compatible blockchain tailored to Era Swap Ecosystem improves the user experience to a higher extent. Since by design, Plasma Framework makes the Era Swap Network as secure as the Ethereum Network, user's funds on the network would be secure as well.
We believe Era Swap Network will help scale dApps of Era Swap Ecosystem to onboard the increasing numbers of users.

11 Years Ago Today Satoshi Nakamoto Published the Bitcoin White Paper

11 Years Ago Today Satoshi Nakamoto Published the Bitcoin White Paper
https://preview.redd.it/comrfanlpuv31.png?width=2000&format=png&auto=webp&s=02324c6250b7dc4aa34313b5fe20ca8b9513dd92
Today, Oct. 31, marks eleven years since the publication of the Bitcoin white paper by the still-mysterious person or group pseudonymously identified as Satoshi Nakamoto.

A revolutionary text

Bitcoin: A Peer-to-Peer Electronic Cash System — published on Oct. 31, 2008 — outlined a tamper-proof, decentralized peer-to-peer protocol that could track and verify digital transactions, prevent double-spending and generate a transparent record for anyone to inspect in nearly real-time.
The protocol represented a cryptographically-secured system — based on a Proof-of-Work algorithm — in which Bitcoins (BTC) are “mined” for a reward by individual nodes and then verified by other nodes in a decentralized network.
This system contained the possibility of overcoming the need for intermediaries such as banks and financial institutions to facilitate and audit transactions — a major disruption to a siloed, monopolized field of centralized financial power.

304033233% all-time-price appreciation

Eleven years on, Bitcoin is consistently setting new records for its network hash rate — a measure of the overall computing power involved in validating transactions on the blockchain at any given time.
More power and participation establishes greater network security and attests to widespread recognition of the profitability potential of Bitcoin mining.
As of the middle of this month, network data revealed that since the creation of the very first block on the Bitcoin blockchain on Jan 3, 2009 — known in more technical language as its “genesis block” — miners have received combined revenue of just under $15 billion.
The figure includes both block rewards — “new” bitcoins paid to miners for validating a block of transactions — as well as transaction fees, which broke the $1 billion mark this week.
Bitcoin’s first-ever recorded trading price was noted on Mar. 17, 2010 — on the now-defunct trading platform bitcoinmarket.com, at a value of $0.003.
The cryptocurrency’s appreciation thus stands at a staggering 304033233% as of press time, with Bitcoin currently trading at $9,120.
As of this August, 85% of Bitcoin’s supply in circulation had been mined — leaving just 3.15 million new coins for the future.
Eleven years on, the mystery enshrouding the white paper’s author remains as impenetrable as ever. Those both within and without the crypto community began attempting to determine Nakamoto’s identity as early as October 2011, just a few months after the mysterious figure first went silent.

When to Sell Bitcoin? ‘Never’ — Mark Yusko Says BTC Like Amazon Stock

When to Sell Bitcoin? ‘Never’ — Mark Yusko Says BTC Like Amazon Stock
https://preview.redd.it/ky7l4t2jn4p31.png?width=1200&format=png&auto=webp&s=49e3f3660787aa481083c1e767fabb8ba22b9fc2
Bitcoin (BTC) is a buy and it has never been the right time to sell it, serial investment manager Mark Yusko has told mainstream media viewers.

Yusko on Bitcoin: All indicators rising

Speaking to CNBC in an interview on Sept. 27, the founder, CEO & chief investment officer of Morgan Creek Capital Management compared Bitcoin’s ten-year history to Amazon.
He was responding to concerns from regular cryptocurrency host Melissa Lee over the Bitcoin price, which fell below $8,000 on Thursday.
For Yusko, while the price of Bitcoin can go up and down, year-on-year growth gives a solid reason to buy and not sell it.
“All the indicators of the network and the network value are rising; the price of any asset fluctuates,” he explained.
Examples included network hash rate, transaction volume and wallet numbers, all of which have continued their upward trajectory this year.

Betting on a bullish return

Yusko thus concluded that selling Bitcoin would be like selling shares in Amazon — so far, there has not been an advantageous point to do so.
“In every year, including this year, it’s had a double-digit drawdown. The average peak-to-trough: 31%, twice 90%. When was the right time to sell? Never,” he said.
Earlier this month, Fundstrat Global Advisors co-founder Tom Lee predicted Bitcoin would rally once the S&P 500 put in new highs.

Initially, I liked SegWit. But then I learned SegWit-as-a-SOFT-fork is dangerous (making transactions "anyone-can-spend"??) & centrally planned (1.7MB blocksize??). Instead, Bitcoin Unlimited is simple & safe, with MARKET-BASED BLOCKSIZE. This is why more & more people have decided to REJECT SEGWIT.

Initially, I liked SegWit. But then I learned SegWit-as-a-SOFT-fork is dangerous (making transactions "anyone-can-spend"??) & centrally planned (1.7MB blocksize??). Instead, Bitcoin Unlimited is simple & safe, with MARKET-BASED BLOCKSIZE. This is why more & more people have decided to REJECT SEGWIT.
Summary
Like many people, I initially loved SegWit - until I found out more about it.
I'm proud of my open-mindedness and my initial - albeit short-lived - support of SegWit - because this shows that I judge software on its merits, instead of being some kind of knee-jerk "hater".
SegWit's idea of "refactoring" the code to separate out the validation stuff made sense, and the phrase "soft fork" sounded cool - for a while.
But then we all learned that:
And we also got much better solutions: such as market-based blocksize with Bitcoin Unlimited - way better than SegWit's arbitrary, random centrally-planned, too-little-too-late 1.7MB "max blocksize".
This is why more and more people are rejecting SegWit - and instead installing Bitcoin Unlimited.
In my case, as I gradually learned about the disastrous consequences which SegWit-as-a-soft-fork-hack would have, my intial single OP in December 2015 expressing outspoken support for SegWit soon turned to an avalanche of outspoken opposition to SegWit.
Details
Core / Blockstream lost my support on SegWit - and it's all their fault.
How did Core / Blockstream turn me from an outspoken SegWit supporter to an outspoken SegWit opponent?
It was simple: They made the totally unnecessary (and dangerous) decision to program SegWit as a messy and dangerous soft-fork which would:
  • create a massive new threat vector by making all transactions "anyone-can-spend";
  • force yet-another random / arbitrary / centrally planned "max blocksize" on everyone (previously 1 MB, now 1.7MB - still pathetically small and hard-coded!).
Meanwhile, new, independent dev teams which are smaller and much better than the corrupt, fiat-financed Core / Blockstream are offering simpler and safer solutions which are much better than SegWit:
  • For blocksize governance, we now have market-based blocksize based on emergent consensus, provided by Bitcoin Unlimited.
  • For malleability and quadratic hashing time (plus a future-proof, tag-based language similar to JSON or XML supporting much cleaner upgrades long-term), we now have Flexible Transactions (FlexTrans).
This is why We Reject SegWit because "SegWit is the most radical and irresponsible protocol upgrade Bitcoin has faced in its history".
My rapid evolution on SegWit - as I discovered its dangers (and as we got much better alternatives, like Bitcoin Unlimited + FlexTrans):
Initially, I was one of the most outspoken supporters of SegWit - raving about it in the following OP which I posted (on Monday, December 7, 2015) immediately after seeing a presentation about it on YouTube by Pieter Wuille at one of the early Bitcoin scaling stalling conferences:
https://np.reddit.com/btc/comments/3vt1ov/pieter_wuilles_segregated_witness_and_fraud/
Pieter Wuille's Segregated Witness and Fraud Proofs (via Soft-Fork!) is a major improvement for scaling and security (and upgrading!)
I am very proud of that initial pro-SegWit post of mine - because it shows that I have always been totally unbiased and impartial and objective about the ideas behind SegWit - and I have always evaluated it purely on its merits (and demerits).
So, I was one of the first people to recognize the positive impact which the ideas behind SegWit could have had (ie, "segregating" the signature information from the sender / receiver / amount information) - if SegWit had been implemented by an honest dev team that supports the interests of the Bitcoin community.
However, we've learned a lot since December 2015. Now we know that Core / Blockstream is actively working against the interests of the Bitcoin community, by:
  • trying to force their political and economic viewpoints onto everyone else by "hard-coding" / "bundling" some random / arbitrary / centrally-planned 1.7MB "max blocksize" (?!?) into our code;
  • trying to take away our right to vote via a clean and safe "hard fork";
  • trying to cripple our code with dangerous "technical debt" - eg their radical and irresponsible proposal to make all transactions "anyone-can-spend".
This is the mess of SegWit - which we all learned about over the past year.
So, Core / Blockstream blew it - bigtime - losing my support for SegWit, and the support of many others in the community.
We might have continued to support SegWit if Core / Blockstream had not implemented it as a dangerous and dirty soft fork.
But Core / Blockstream lost our support - by attempting to implement SegWit as a dangerous, anti-democratic soft fork.
The lesson here for Core/Blockstream is clear:
Bitcoin users are not stupid.
Many of us are programmers ourselves, and we know the difference between a simple & safe hard fork and a messy & dangerous soft fork.
And we also don't like it when Core / Blockstream attempts to take away our right to vote.
And finally, we don't like it when Core / Blockstream attempts to steal functionality away from nodes while using misleading terminology - as u/chinawat has repeatedly been pointing out lately.
We know a messy, dangerous, centrally planned hack when we see it - and SegWit is a messy, dangerous, centrally planned hack.
If Core/Blockstream attempts to foce messy and dangerous code like SegWit-as-a-soft-fork on the community, we can and should and we will reject SegWit - to protect our billions of dollars of investment in Bitcoin (which could turn into trillions of dollars someday - if we continue to protect our code from poison pills and trojans like SegWit).
Too bad you lost my support (and the support of many, many other Bitcoin users), Core / Blockstream! But it's your own fault for releasing shitty code.
Below are some earlier comments from me showing how I quickly turned from one of the most outspoken supporters of Segwit (in that single OP I wrote the day I saw Pieter Wuille's presentation on YouTube) - into one of most outspoken opponents of SegWit:
I also think Pieter Wuille is a great programmer and I was one of the first people to support SegWit after it was announced at a congress a few months ago.
But then Blockstream went and distorted SegWit to fit it into their corporate interests (maintaining their position as the dominant centralized dev team - which requires avoiding hard-forks). And Blockstream's corporate interests don't always align with Bitcoin's interests.
https://np.reddit.com/btc/comments/57zbkp/if_blockstream_were_truly_conservative_and_wanted/
As noted in the link in the section title above, I myself was an outspoken supporter championing SegWit on the day when I first the YouTube of Pieter Wuille explaining it at one of the early "Scaling Bitcoin" conferences.
Then I found out that doing it as a soft fork would add unnecessary "spaghetti code" - and I became one of the most outspoken opponents of SegWit.
https://np.reddit.com/btc/comments/5ejmin/coreblockstream_is_living_in_a_fantasy_world_in/
Pieter Wuille's SegWit would be a great refactoring and clean-up of the code (if we don't let Luke-Jr poison it by packaging it as a soft-fork)
https://np.reddit.com/btc/comments/4kxtq4/i_think_the_berlin_wall_principle_will_end_up/
Probably the only prominent Core/Blockstream dev who does understand this kind of stuff like the Robustness Principle or its equivalent reformulation in terms of covariant and contravariant types is someone like Pieter Wuille – since he’s a guy who’s done a lot of work in functional languages like Haskell – instead of being a myopic C-tard like most of the rest of the Core/Blockstream devs. He’s a smart guy, and his work on SegWit is really important stuff (but too bad that, yet again, it’s being misdelivered as a “soft-fork,” again due to the cluelessness of someone like Luke-Jr, whose grasp of syntax and semantics – not to mention society – is so glaringly lacking that he should have been recognized for the toxic influence that he is and shunned long ago).
https://np.reddit.com/btc/comments/4k6tke/the_tragedy_of/
The damage which would be caused by SegWit (at the financial, software, and governance level) would be massive:
  • Millions of lines of other Bitcoin code would have to be rewritten (in wallets, on exchanges, at businesses) in order to become compatible with all the messy non-standard kludges and workarounds which Blockstream was forced into adding to the code (the famous "technical debt") in order to get SegWit to work as a soft fork.
  • SegWit was originally sold to us as a "code clean-up". Heck, even I intially fell for it when I saw an early presentation by Pieter Wuille on YouTube from one of Blockstream's many, censored Bitcoin scaling stalling conferences)
  • But as we all later all discovered, SegWit is just a messy hack.
  • Probably the most dangerous aspect of SegWit is that it changes all transactions into "ANYONE-CAN-SPEND" without SegWit - all because of the messy workarounds necessary to do SegWit as a soft-fork. The kludges and workarounds involving SegWit's "ANYONE-CAN-SPEND" semantics would only work as long as SegWit is still installed.
  • This means that it would be impossible to roll-back SegWit - because all SegWit transactions that get recorded on the blockchain would now be interpreted as "ANYONE-CAN-SPEND" - so, SegWit's dangerous and messy "kludges and workarounds and hacks" would have to be made permanent - otherwise, anyone could spend those "ANYONE-CAN-SPEND" SegWit coins!
Segwit cannot be rolled back because to non-upgraded clients, ANYONE can spend Segwit txn outputs. If Segwit is rolled back, all funds locked in Segwit outputs can be taken by anyone. As more funds gets locked up in segwit outputs, incentive for miners to collude to claim them grows.

Why are more and more people (including me!) rejecting SegWit?
(1) SegWit is the most radical and irresponsible change ever proposed for Bitcoin:
"SegWit encumbers Bitcoin with irreversible technical debt. Miners should reject SWSF. SW is the most radical and irresponsible protocol upgrade Bitcoin has faced in its history. The scale of the code changes are far from trivial - nearly every part of the codebase is affected by SW" Jaqen Hash’ghar
https://np.reddit.com/btc/comments/5rdl1j/segwit_encumbers_bitcoin_with_irreversible/
3 excellent articles highlighting some of the major problems with SegWit: (1) "Core Segwit – Thinking of upgrading? You need to read this!" by WallStreetTechnologist (2) "SegWit is not great" by Deadalnix (3) "How Software Gets Bloated: From Telephony to Bitcoin" by Emin Gün Sirer
https://np.reddit.com/btc/comments/5rfh4i/3_excellent_articles_highlighting_some_of_the/
"The scaling argument was ridiculous at first, and now it's sinister. Core wants to take transactions away from miners to give to their banking buddies - crippling Bitcoin to only be able to do settlements. They are destroying Satoshi's vision. SegwitCoin is Bankcoin, not Bitcoin" ~ u/ZeroFucksG1v3n
https://np.reddit.com/btc/comments/5rbug3/the_scaling_argument_was_ridiculous_at_first_and/
u/Uptrenda on SegWit: "Core is forcing every Bitcoin startup to abandon their entire code base for a Rube Goldberg machine making their products so slow, inconvenient, and confusing that even if they do manage to 'migrate' to this cluster-fuck of technical debt it will kill their businesses anyway."
https://np.reddit.com/btc/comments/5e86fg/uuptrenda_on_segwit_core_is_forcing_every_bitcoin/
"SegWit [would] bring unnecessary complexity to the bitcoin blockchain. Huge changes it introduces into the client are a veritable minefield of issues, [with] huge changes needed for all wallets, exchanges, remittance, and virtually all bitcoin software that will use it." ~ u/Bitcoinopoly
https://np.reddit.com/btc/comments/5jqgpz/segwit_would_bring_unnecessary_complexity_to_the/
Just because something is a "soft fork" doesn't mean it isn't a massive change. SegWit is an alt-coin. It would introduce radical and unpredictable changes in Bitcoin's economic parameters and incentives. Just read this thread. Nobody has any idea how the mainnet will react to SegWit in real life.
https://np.reddit.com/btc/comments/5fc1ii/just_because_something_is_a_soft_fork_doesnt_mean/
Core/Blockstream & their supporters keep saying that "SegWit has been tested". But this is false. Other software used by miners, exchanges, Bitcoin hardware manufacturers, non-Core software developers/companies, and Bitcoin enthusiasts would all need to be rewritten, to be compatible with SegWit
https://np.reddit.com/btc/comments/5dlyz7/coreblockstream_their_supporters_keep_saying_that/
SegWit-as-a-softfork is a hack. Flexible-Transactions-as-a-hard-fork is simpler, safer and more future-proof than SegWit-as-a-soft-fork - trivially solving malleability, while adding a "tag-based" binary data format (like JSON, XML or HTML) for easier, safer future upgrades with less technical debt
https://np.reddit.com/btc/comments/5a7husegwitasasoftfork_is_a_hack/
(2) Better solutions than SegWit are now available (Bitcoin Unlimited, FlexTrans):
ViABTC: "Why I support BU: We should give the question of block size to the free market to decide. It will naturally adjust to ever-improving network & technological constraints. Bitcoin Unlimited guarantees that block size will follow what the Bitcoin network is capable of handling safely."
https://np.reddit.com/btc/comments/574g5l/viabtc_why_i_support_bu_we_should_give_the/
"Why is Flexible Transactions more future-proof than SegWit?" by u/ThomasZander
https://np.reddit.com/btc/comments/5rbv1j/why_is_flexible_transactions_more_futureproof/
Bitcoin's specification (eg: Excess Blocksize (EB) & Acceptance Depth (AD), configurable via Bitcoin Unlimited) can, should & always WILL be decided by ALL the miners & users - not by a single FIAT-FUNDED, CENSORSHIP-SUPPORTED dev team (Core/Blockstream) & miner (BitFury) pushing SegWit 1.7MB blocks
https://np.reddit.com/btc/comments/5u1r2d/bitcoins_specification_eg_excess_blocksize_eb/
The Blockstream/SegWit/LN fork will be worth LESS: SegWit uses 4MB storage/bandwidth to provide a one-time bump to 1.7MB blocksize; messy, less-safe as softfork; LN=vaporware. The BU fork will be worth MORE: single clean safe hardfork solving blocksize forever; on-chain; fix malleability separately.
https://np.reddit.com/btc/comments/57zjnk/the_blockstreamsegwitln_fork_will_be_worth_less/
(3) Very few miners actually support SegWit. In fact, over half of SegWit signaling comes from just two fiat-funded miners associated with Core / Blockstream: BitFury and BTCC:
Brock Pierce's BLOCKCHAIN CAPITAL is part-owner of Bitcoin's biggest, private, fiat-funded private dev team (Blockstream) & biggest, private, fiat-funded private mining operation (BitFury). Both are pushing SegWit - with its "centrally planned blocksize" & dangerous "anyone-can-spend kludge".

(4) Hard forks are simpler and safer than soft forks. Hard forks preserve your "right to vote" - so Core / Blockstream is afraid of hard forks a/k/a "full node refendums" - because they know their code would be rejected:
The real reason why Core / Blockstream always favors soft-forks over hard-forks (even though hard-forks are actually safer because hard-forks are explicit) is because soft-forks allow the "incumbent" code to quietly remain incumbent forever (and in this case, the "incumbent" code is Core)

Reminder: Previous posts showing that Blockstream's opposition to hard-forks is dangerous, obstructionist, selfish FUD. As many of us already know, the reason that Blockstream is against hard forks is simple: Hard forks are good for Bitcoin, but bad for the private company Blockstream.

"They [Core/Blockstream] fear a hard fork will remove them from their dominant position." ... "Hard forks are 'dangerous' because they put the market in charge, and the market might vote against '[the] experts' [at Core/Blockstream]" - ForkiusMaximus

The proper terminology for a "hard fork" should be a "FULL NODE REFERENDUM" - an open, transparent EXPLICIT process where everyone has the right to vote FOR or AGAINST an upgrade. The proper terminology for a "soft fork" should be a "SNEAKY TROJAN HORSE" - because IT TAKES AWAY YOUR RIGHT TO VOTE.

If Blockstream were truly "conservative" and wanted to "protect Bitcoin" then they would deploy SegWit AS A HARD FORK. Insisting on deploying SegWit as a soft fork (overly complicated so more dangerous for Bitcoin) exposes that they are LYING about being "conservative" and "protecting Bitcoin".

"We had our arms twisted to accept 2MB hardfork + SegWit. We then got a bait and switch 1MB + SegWit with no hardfork, and accounting tricks to make P2SH transactions cheaper (for sidechains and Lightning, which is all Blockstream wants because they can use it to control Bitcoin)." ~ u/URGOVERNMENT
https://np.reddit.com/btc/comments/5ju5r8/we_had_our_arms_twisted_to_accept_2mb_hardfork/
u/Luke-Jr invented SegWit's dangerous "anyone-can-spend" soft-fork kludge. Now he helped kill Bitcoin trading at Circle. He thinks Bitcoin should only hard-fork TO DEAL WITH QUANTUM COMPUTING. Luke-Jr will continue to kill Bitcoin if we continue to let him. To prosper, BITCOIN MUST IGNORE LUKE-JR.
https://np.reddit.com/btc/comments/5h0yf0/ulukejr_invented_segwits_dangerous_anyonecanspend/
Normal users understand that SegWit-as-a-softfork is dangerous, because it deceives non-upgraded nodes into thinking transactions are valid when actually they're not - turning those nodes into "zombie nodes". Greg Maxwell and Blockstream are jeopardizing Bitcoin - in order to stay in power.

"Negotiations have failed. BS/Core will never HF - except to fire the miners and create an altcoin. Malleability & quadratic verification time should be fixed - but not via SWSF political/economic trojan horse. CHANGES TO BITCOIN ECONOMICS MUST BE THRU FULL NODE REFERENDUM OF A HF." ~ u/TunaMelt

"Anything controversial ... is the perfect time for a hard fork. ... Hard forks are the market speaking. Soft forks on any issues where there is controversy are an attempt to smother the market in its sleep. Core's approach is fundamentally anti-market" ~ u/ForkiusMaximus
https://np.reddit.com/btc/comments/5f4zaa/anything_controversial_is_the_perfect_time_for_a/
As Core / Blockstream collapses and Classic gains momentum, the CEO of Blockstream, Austin Hill, gets caught spreading FUD about the safety of "hard forks", falsely claiming that: "A hard-fork forced-upgrade flag day ... disenfranchises everyone who doesn't upgrade ... causes them to lose funds"
https://np.reddit.com/btc/comments/41c8n5/as_core_blockstream_collapses_and_classic_gains/
Core/Blockstream is living in a fantasy world. In the real world everyone knows (1) our hardware can support 4-8 MB (even with the Great Firewall), and (2) hard forks are cleaner than soft forks. Core/Blockstream refuses to offer either of these things. Other implementations (eg: BU) can offer both.
https://np.reddit.com/btc/comments/5ejmin/coreblockstream_is_living_in_a_fantasy_world_in/
Blockstream is "just another shitty startup. A 30-second review of their business plan makes it obvious that LN was never going to happen. Due to elasticity of demand, users either go to another coin, or don't use crypto at all. There is no demand for degraded 'off-chain' services." ~ u/jeanduluoz
https://np.reddit.com/btc/comments/59hcvblockstream_is_just_another_shitty_startup_a/
(5) Core / Blockstream's latest propaganda "talking point" proclaims that "SegWit is a blocksize increase". But we don't want "a" random, arbitrary centrally planned blocksize increase (to a tiny 1.7MB) - we want _market-based blocksizes - now and into the future:_
The debate is not "SHOULD THE BLOCKSIZE BE 1MB VERSUS 1.7MB?". The debate is: "WHO SHOULD DECIDE THE BLOCKSIZE?" (1) Should an obsolete temporary anti-spam hack freeze blocks at 1MB? (2) Should a centralized dev team soft-fork the blocksize to 1.7MB? (3) OR SHOULD THE MARKET DECIDE THE BLOCKSIZE?
https://np.reddit.com/btc/comments/5pcpec/the_debate_is_not_should_the_blocksize_be_1mb/
The Bitcoin community is talking. Why isn't Core/Blockstream listening? "Yes, [SegWit] increases the blocksize but BU wants a literal blocksize increase." ~ u/lurker_derp ... "It's pretty clear that they [BU-ers] want Bitcoin, not a BTC fork, to have a bigger blocksize." ~ u/WellSpentTime
https://np.reddit.com/btc/comments/5fjh6l/the_bitcoin_community_is_talking_why_isnt/
"The MAJORITY of the community sentiment (be it miners or users / hodlers) is in favour of the manner in which BU handles the scaling conundrum (only a conundrum due to the junta at Core) and SegWit as a hard and not a soft fork." ~ u/pekatete
https://np.reddit.com/btc/comments/593voi/the_majority_of_the_community_sentiment_be_it/
(6) Core / Blockstream want to radically change Bitcoin to centrally planned 1.7MB blocksize, and dangerous "anyone-can-spend" semantics. The market wants to go to the moon - with Bitcoin's original security model, and Bitcoin's original market-based (miner-decided) blocksize.
Bitcoin Unlimited is the real Bitcoin, in line with Satoshi's vision. Meanwhile, BlockstreamCoin+RBF+SegWitAsASoftFork+LightningCentralizedHub-OfflineIOUCoin is some kind of weird unrecognizable double-spendable non-consensus-driven fiat-financed offline centralized settlement-only non-P2P "altcoin"
https://np.reddit.com/btc/comments/57brcb/bitcoin_unlimited_is_the_real_bitcoin_in_line/
The number of blocks being mined by Bitcoin Unlimited is now getting very close to surpassing the number of blocks being mined by SegWit! More and more people are supporting BU's MARKET-BASED BLOCKSIZE - because BU avoids needless transaction delays and ultimately increases Bitcoin adoption & price!
https://np.reddit.com/btc/comments/5rdhzh/the_number_of_blocks_being_mined_by_bitcoin/
I have just been banned for from /Bitcoin for posting evidence that there is a moderate/strong inverse correlation between the amount of Bitcoin Core Blocks mined and the Bitcoin Price (meaning that as Core loses market share, Price goes up).
https://np.reddit.com/btc/comments/5v10zw/i_have_just_been_banned_for_from_rbitcoin_fo
Flipping the Script: It is Core who is proposing a change to Bitcoin, and BU/Classic that is maintaining the status quo.
https://np.reddit.com/btc/comments/5v36jy/flipping_the_script_it_is_core_who_is_proposing_a/
The main difference between Bitcoin core and BU client is BU developers dont bundle their economic and political opinions with their code
https://np.reddit.com/btc/comments/5v3rt2/the_main_difference_between_bitcoin_core_and_bu/
TL;DR:
You wanted people like me to support you and install your code, Core / Blockstream?
Then you shouldn't have a released messy, dangerous, centrally planned hack like SegWit-as-a-soft-fork - with its random, arbitrary, centrally planned, ridiculously tiny 1.7MB blocksize - and its dangerous "anyone-can-spend" soft-fork semantics.
Now it's too late. The market will reject SegWit - and it's all Core / Blockstream's fault.
The market prefers simpler, safer, future-proof, market-based solutions such as Bitcoin Unlimited.
