AMA: Learn about One Artist's Journey to paint all 12.8 million digits of Satoshi's BTC codebase. $21 per question answered will be donated charity!
Hello Reddit!
Portraits of a Mind is a global art project to decentralise the founding code behind Bitcoin into 40 fragments. The largest work of art in blockchain history, the work runs to 50 meters in length and forms an entire physical transcription of the 12.8 million digits of code that Satoshi compiled on his laptops over 11 years ago.
The Collectors of the project and Robert Alice will be donating $21 for every question answered, split between CoinCenter and Social Alpha Foundation.
SO ASK ME ANYTHING ABOUT THE MAKING OF THE PROJECT......and lets raise some money!
MORE INFO ON THE PROJECT

The first 20 works were decentralised privately to 14 cities across 3 continents, acquired by some of the most important people in the space, from CZ to Matt Roszak. From San Francisco to Tokyo, the global spread of the works stands testament to you - the crypto community and its globalised nature.
On Wednesday, in just 48 hours time, BLOCK 21 from Portraits of a Mind will make history as the first artwork and NFT of our culture to be sold at Christie's New York. Just eleven years on from its inception, Satoshi's codebase currently hangs alongside masterpieces by Picasso, Cezanne, Rothko, Jackson Pollock and Warhol.
It is a major moment for our culture on the global stage and a moment to reflect on how deeply this codebase has ingrained itself into contemporary society in such a short space of time.

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low
Bearish:
A tendency of prices to fall; a pessimistic expectation that the value of a coin is going to drop.
Bear trap:
A manipulation of a stock or commodity by investors.
Bitcoin:
The very first, and the highest ever valued, mass-market open source and decentralized cryptocurrency and digital payment system that runs on a worldwide peer to peer network. It operates independently of any centralized authorities
Bitconnect:
One of the biggest scams in the crypto world. it was made popular in the meme world by screaming idiot Carlos Matos, who infamously proclaimed," hey hey heeeey” and “what's a what's a what's up wasssssssssuuuuuuuuuuuuup, BitConneeeeeeeeeeeeeeeeeeeeeeeect!”. He is now in the mentally ill meme hall of fame.
Block:
A package of permanently recorded data about transactions occurring every time period (typically about 10 minutes) on the blockchain network. Once a record has been completed and verified, it goes into a blockchain and gives way to the next block. Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:
An unchangeable digital record of all transactions ever made in a particular cryptocurrency and shared across thousands of computers worldwide. It has no central authority governing it. Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.
Bull market:
A market that Cryptos are going up.
Consensus:
An agreement among blockchain participants on the validity of data. Consensus is reached when the majority of nodes on the network verify that the transaction is 100% valid.
Crypto bubble:
The instability of cryptocurrencies in terms of price value
Cryptocurrency:
A type of digital currency, secured by strong computer code (cryptography), that operates independently of any middlemen or central authoritie
Cryptography:
The art of converting sensitive data into a format unreadable for unauthorized users, which when decoded would result in a meaningful statement.
Cryptojacking:
The use of someone else’s device and profiting from its computational power to mine cryptocurrency without their knowledge and consent.
Crypto-Valhalla:
When HODLers(holders) eventually cash out they go to a place called crypto-Valhalla. The strong will be separated from the weak and the strong will then be given lambos.
DAO:
Decentralized Autonomous Organizations. It defines A blockchain technology inspired organization or corporation that exists and operates without human intervention.
Dapp (decentralized application):
An open-source application that runs and stores its data on a blockchain network (instead of a central server) to prevent a single failure point. This software is not controlled by the single body – information comes from people providing other people with data or computing power.
Decentralized:
A system with no fundamental control authority that governs the network. Instead, it is jointly managed by all users to the system.
Desktop wallet:
A wallet that stores the private keys on your computer, which allow the spending and management of your bitcoins.
DILDO:
Long red or green candles. This is a crypto signal that tells you that it is not favorable to trade at the moment. Found on candlestick charts.
Digital Signature:
An encrypted digital code attached to an electronic document to prove that the sender is who they say they are and confirm that a transaction is valid and should be accepted by the network.
Double Spending:
An attack on the blockchain where a malicious user manipulates the network by sending digital money to two different recipients at exactly the same time.
DYOR:
Means do your own research.
Encryption:
Converting data into code to protect it from unauthorized access, so that only the intended recipient(s) can decode it.
Eskrow:
the practice of having a third party act as an intermediary in a transaction. This third party holds the funds on and sends them off when the transaction is completed.
Ethereum:
Ethereum is an open source, public, blockchain-based platform that runs smart contracts and allows you to build dapps on it. Ethereum is fueled by the cryptocurrency Ether.
Exchange:
A platform (centralized or decentralized) for exchanging (trading) different forms of cryptocurrencies. These exchanges allow you to exchange cryptos for local currency. Some popular exchanges are Coinbase, Bittrex, Kraken and more.
Faucet:
A website which gives away free cryptocurrencies.
Fiat money:
Fiat currency is legal tender whose value is backed by the government that issued it, such as the US dollar or UK pound.
Fork:
A split in the blockchain, resulting in two separate branches, an original and a new alternate version of the cryptocurrency. As a single blockchain forks into two, they will both run simultaneously on different parts of the network. For example, Bitcoin Cash is a Bitcoin fork.
FOMO:
Fear of missing out.
Frictionless:
A system is frictionless when there are zero transaction costs or trading retraints.
FUD:
Fear, Uncertainty and Doubt regarding the crypto market.
Gas:
A fee paid to run transactions, dapps and smart contracts on Ethereum.
Halving:
A 50% decrease in block reward after the mining of a pre-specified number of blocks. Every 4 years, the “reward” for successfully mining a block of bitcoin is reduced by half. This is referred to as “Halving”.
Hardware wallet:
Physical wallet devices that can securely store cryptocurrency maximally. Some examples are Ledger Nano S**,** Digital Bitbox and more**.**
Hash:
The process that takes input data of varying sizes, performs an operation on it and converts it into a fixed size output. It cannot be reversed.
Hashing:
The process by which you mine bitcoin or similar cryptocurrency, by trying to solve the mathematical problem within it, using cryptographic hash functions.

Cash: use it or lose it!

Is this the last decade of cash?

The corona pandemic is not helping. Belgian media is picking up the Australian news about the coronavirus found active 28 days on banknotes, without understanding that the 28 days is on the Australian polymer and paper banknotes, while Euro banknotes are made of cotton fibers on which the coronavirus gets inactive rather quick. https://medicalxpress.com/news/2020-04-euro-banknotes-safe-coronavirus-ecb.html
You are touching so much in shops, including the pay terminals everyone is touching, that cash won't add much risk.

Until this year, I used to not care, and pay everything electronically.

But in March I became the victim of an identity theft. My bank account was frozen, my bank cards and payment app blocked. Opening new bank accounts or credit cards was impossible due to being on a blacklist.

My employer could not pay my salary in cash. For most professions this is forbidden by law since 2016.

Friends lent me cash. But I discovered cash was refused at supermarkets, shops, public transport, parkings, fuel stations, hospital, physiotherapist, online webshops, Uber, Deliveroo, etc. Sometimes because of corona anxiety, but often already from before 2020.

Prepaid cards could be a nice solution. But even while they are debit cards, in Belgium they seem to be refused where credit cards are refused, since they are Visa or Mastercards cards. These are refused in many Belgium places, since merchants don't like the higher costs. Not many prepaid cards allow charging with cash. And their availability is in recent decline: this year at least the following prepaid cards stopped or are announced to stop: Carrefour prepaid Flex card, BNP and Hello. The decline might be due to new very strict EU anti-money laundering laws. The anonymous prepaid cards (and generic gift cards) are now restricted to 100 euro maximum recharge in their lifetime and 50 euro payments.

Cryptocurrencies are also in theory a nice solution. But their acceptance in Belgium is extremely limited. Thanks to Takeaway accepting bitcoin, I could order delivery from many local snack restaurants.
But I discovered that bitcoin and most other cryptocurrencies, while having an "anonymous" reputation, are actually only pseudonymous and extremely open and transparent: for every transaction the origin address, destination address, amount and timestamp are recorded for eternity in a public ledger for everyone open to consult. When I buy something, the merchant can see how many coins I have in my wallet address. Buying, spending or selling coins are activities that can get your name connected to your addresses. Developers try to solve this privacy issue, but I'm afraid the war on anonymity (related to the war on cash) will crush that before cryptocurrency payments become popular.

So, my identity theft experience has awakened me: sharing your personal details in so many places caries a lot of danger. Think about it: while the law became more strict, there are still many (online) shops and restaurants taking knowledge of your credit card number, expiry date, CCV and your name. That's still enough information to do fraudulent payments in many places.

The cashless society is a surveillance society, with every payment traced. And it creates a lot of dependencies: electricity, internet, and permission by the banking and payment system. Once you are on a blacklist, even if you did nothing wrong, but somebody pretended to be you and did fraudulent payments, you are screwed for at least months.

So, now that I'm finally off the blacklist, I opened several bank accounts. That will not help for all issues, but still: having only 1 bank is really dangerous.

And from now on I pay everything possible with cash. Not just to keep my personal details safe, but also to keep the cash usage statistics high. Did you notice that the financial sector is regulary reporting the cash withdrawals decline? They report both the total amount withdrawn and the number of withdrawals.

I learned that the bank and payment processors are fighting a war on cash and they are actively lobbying the government for a reduction of the cash payment limit to 50 euro. Yes, an insane fifty euro! The banks are lazy about cash and want to impose negative rent without risking a bankrun. No cash is no bankrun. The payment processors just love the percentage they get from every payment.

Currently the acceptance of euro banknotes and coins for debts is compulsory by European law. But many merchants violated the law and we had at least one Belgian minister ignoring the enforcement. See e.g. this article from 2019: https://www.bruzz.be/samenleving/no-cash-doet-intrede-brusselse-horeca-2019-05-10.
The law has exceptions, e.g. for security reasons such as a pandemic. After the pandemic I will try to report all cash refusing merchants.
Merchants that refuse to accept cash payments can be reported at https://meldpunt.belgie.be or https://pointdecontact.belgique.be/. But I guess it is better to wait until after the pandemic.

We need to defend the right to use cash. And a crucial action to avoid the end of cash is to keep using it as much as possible.

Every time you pay with a bank card or app, you contribute to a cashless future where:
Use cash or lose it!

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer.

Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Advice About Bitcoin Transaction Fees (In anticipation of high fees for the next bullrun)

Hi guys, this is my first post here!
Thanks for having me, I interact a lot on Bitcoin and crypto groups on Facebook but I wanted to find new Bitcoin folks and discussions here!
The other day I saw someone complaining about the wait time for a Bitcoin transaction so I wrote a few pieces of advice in regards to Bitcoin transaction fees. I hope this can be useful for some of you!
Here it is:
For those worried about Bitcoin's high transaction fees and transaction wait times right now, you should brace yourself for the upcoming TRUE Bitcoin Bullrun.
Remember that in 2017, at the peak of the bubble, the average transaction fee was up to $ 50 per transaction and some people even paid $ 1000 for single transactions.
This is sure to repeat itself at an unprecedented level as I believe this time around an even bigger wave of people will be buying Bitcoin. Not only investors like you and me, but also big companies who will buy in tens and hundreds of millions.
Here are some tips to mitigate the impact of transaction fees on your use of Bitcoin.

1. Learn How to Use the Mempool.

The mempool is the space where valid Bitcoin transactions are stored while waiting to be included in a validated Bitcoin block. Obviously, miners will select transactions with higher transaction fees to fill up a valid block.
I recommend this mempool explorer which visually represents how full the mempool is and will indicate to you how many satoshi /vbyte you need to apply on your transaction in order for it to be included in your desired timeframe.
Fee estimators in wallets are not ideal and ultimately none of them has found the perfect recipe for proper fee estimation. Selecting the transaction fee manually by consulting the mempool remains the best option to select the fee.
A few tips:

2. Use wallets that support Segwit and RBF (Replace by Fee)

Segwit is an improvement made to Bitcoin in 2017 that redefined the way transactions take space in a block. Just by using a Bitcoin wallet that supports it, you will save between 20-60% in fees depending on the complexity of the transaction.
RBF is a function in wallets that allows you to modify the transaction fees associated with a transaction following its broadcast on the Bitcoin network. So, if your transaction does not go through quickly enough for your liking, you can increase the fee later.
To find out which Bitcoin software wallet supports both features, you can consult this comparison table from Veriphi where they list several dozen wallets here.
Fun fact:
Veriphi also made a case study to find out how many fees could have been saved by Bitcoin users if they had used SEGWIT and the Batching technique in the cases where they apply.

Results

Between 2012 and August 2020, more than 57,817 .69 BITCOINS would have been saved in transaction costs, or approximately 1 billion Canadian Dollars in transaction fees. For those who are interested in the results, check it out more in detail here.

3. Do not leave your coins on a platform (Bonus: Use a immediate delivery platform)

Custodial exchanges often block Bitcoin withdrawals during high transaction volume episodes because they do not want to pay their user's Bitcoin transaction fees. If they don't block it they will often make their user overpay for the transactions fees.
This has happened in the PAST and even quite recently, so if you want to avoid a lot of the frustration and stress when the Bullrun comes, remove your coins from there before it is too late, preferably right now.
Some non-custodial platform in Canada:
veriphi.io
Bullbitcoin.com
I strongly anticipate the increase in transaction fees. Watch out for platforms that haven't implemented transaction optimization techniques yet, they will have the hardest time sending transactions.
Check out this article about the advantages of an immediate delivery platform here.

Conclusion

High Bitcoin transaction fees are inevitable in Bitcoin and even desired because they will one day have to replace the block rewards. This is a demonstration that Bitcoin works and that the world is using it.
By adopting the best practices and the right technologies, you will be able to mitigate your costs and accumulate more Bitcoin in the end.

*Disclaimer: I work at Veriphi.io but didn't want to be too pushy, I hope you appreciate the tips and the provided resources.
Cheers

Proposal: The Sia Foundation

Vision Statement

A common sentiment is brewing online; a shared desire for the internet that might have been. After decades of corporate encroachment, you don't need to be a power user to realize that something has gone very wrong.
In the early days of the internet, the future was bright. In that future, when you sent an instant message, it traveled directly to the recipient. When you needed to pay a friend, you announced a transfer of value to their public key. When an app was missing a feature you wanted, you opened up the source code and implemented it. When you took a picture on your phone, it was immediately encrypted and backed up to storage that you controlled. In that future, people would laugh at the idea of having to authenticate themselves to some corporation before doing these things.
What did we get instead? Rather than a network of human-sized communities, we have a handful of enormous commons, each controlled by a faceless corporate entity. Hey user, want to send a message? You can, but we'll store a copy of it indefinitely, unencrypted, for our preference-learning algorithms to pore over; how else could we slap targeted ads on every piece of content you see? Want to pay a friend? You can—in our Monopoly money. Want a new feature? Submit a request to our Support Center and we'll totally maybe think about it. Want to backup a photo? You can—inside our walled garden, which only we (and the NSA, of course) can access. Just be careful what you share, because merely locking you out of your account and deleting all your data is far from the worst thing we could do.
You rationalize this: "MEGACORP would never do such a thing; it would be bad for business." But we all know, at some level, that this state of affairs, this inversion of power, is not merely "unfortunate" or "suboptimal" – No. It is degrading. Even if MEGACORP were purely benevolent, it is degrading that we must ask its permission to talk to our friends; that we must rely on it to safeguard our treasured memories; that our digital lives are completely beholden to those who seek only to extract value from us.
At the root of this issue is the centralization of data. MEGACORP can surveil you—because your emails and video chats flow through their servers. And MEGACORP can control you—because they hold your data hostage. But centralization is a solution to a technical problem: How can we make the user's data accessible from anywhere in the world, on any device? For a long time, no alternative solution to this problem was forthcoming.
Today, thanks to a confluence of established techniques and recent innovations, we have solved the accessibility problem without resorting to centralization. Hashing, encryption, and erasure encoding got us most of the way, but one barrier remained: incentives. How do you incentivize an anonymous stranger to store your data? Earlier protocols like BitTorrent worked around this limitation by relying on altruism, tit-for-tat requirements, or "points" – in other words, nothing you could pay your electric bill with. Finally, in 2009, a solution appeared: Bitcoin. Not long after, Sia was born.
Cryptography has unleashed the latent power of the internet by enabling interactions between mutually-distrustful parties. Sia harnesses this power to turn the cloud storage market into a proper marketplace, where buyers and sellers can transact directly, with no intermediaries, anywhere in the world. No more silos or walled gardens: your data is encrypted, so it can't be spied on, and it's stored on many servers, so no single entity can hold it hostage. Thanks to projects like Sia, the internet is being re-decentralized.
Sia began its life as a startup, which means it has always been subjected to two competing forces: the ideals of its founders, and the profit motive inherent to all businesses. Its founders have taken great pains to never compromise on the former, but this often threatened the company's financial viability. With the establishment of the Sia Foundation, this tension is resolved. The Foundation, freed of the obligation to generate profit, is a pure embodiment of the ideals from which Sia originally sprung.
The goals and responsibilities of the Foundation are numerous: to maintain core Sia protocols and consensus code; to support developers building on top of Sia and its protocols; to promote Sia and facilitate partnerships in other spheres and communities; to ensure that users can easily acquire and safely store siacoins; to develop network scalability solutions; to implement hardforks and lead the community through them; and much more. In a broader sense, its mission is to commoditize data storage, making it cheap, ubiquitous, and accessible to all, without compromising privacy or performance.
Sia is a perfect example of how we can achieve better living through cryptography. We now begin a new chapter in Sia's history. May our stewardship lead it into a bright future.
 

Overview

Today, we are proposing the creation of the Sia Foundation: a new non-profit entity that builds and supports distributed cloud storage infrastructure, with a specific focus on the Sia storage platform. What follows is an informal overview of the Sia Foundation, covering two major topics: how the Foundation will be funded, and what its funds will be used for.

Organizational Structure

The Sia Foundation will be structured as a non-profit entity incorporated in the United States, likely a 501(c)(3) organization or similar. The actions of the Foundation will be constrained by its charter, which formalizes the specific obligations and overall mission outlined in this document. The charter will be updated on an annual basis to reflect the current goals of the Sia community.
The organization will be operated by a board of directors, initially comprising Luke Champine as President and Eddie Wang as Chairman. Luke Champine will be leaving his position at Nebulous to work at the Foundation full-time, and will seek to divest his shares of Nebulous stock along with other potential conflicts of interest. Neither Luke nor Eddie personally own any siafunds or significant quantities of siacoin.

Funding

The primary source of funding for the Foundation will come from a new block subsidy. Following a hardfork, 30 KS per block will be allocated to the "Foundation Fund," continuing in perpetuity. The existing 30 KS per block miner reward is not affected. Additionally, one year's worth of block subsidies (approximately 1.57 GS) will be allocated to the Fund immediately upon activation of the hardfork.
As detailed below, the Foundation will provably burn any coins that it cannot meaningfully spend. As such, the 30 KS subsidy should be viewed as a maximum. This allows the Foundation to grow alongside Sia without requiring additional hardforks.
The Foundation will not be funded to any degree by the possession or sale of siafunds. Siafunds were originally introduced as a means of incentivizing growth, and we still believe in their effectiveness: a siafund holder wants to increase the amount of storage on Sia as much as possible. While the Foundation obviously wants Sia to succeed, its driving force should be its charter. Deriving significant revenue from siafunds would jeopardize the Foundation's impartiality and focus. Ultimately, we want the Foundation to act in the best interests of Sia, not in growing its own budget.

Responsibilities

The Foundation inherits a great number of responsibilities from Nebulous. Each quarter, the Foundation will publish the progress it has made over the past quarter, and list the responsibilities it intends to prioritize over the coming quarter. This will be accompanied by a financial report, detailing each area of expenditure over the past quarter, and forecasting expenditures for the coming quarter. Below, we summarize some of the myriad responsibilities towards which the Foundation is expected to allocate its resources.

Maintain and enhance core Sia software

Arguably, this is the most important responsibility of the Foundation. At the heart of Sia is its consensus algorithm: regardless of other differences, all Sia software must agree upon the content and rules of the blockchain. It is therefore crucial that the algorithm be stewarded by an entity that is accountable to the community, transparent in its decision-making, and has no profit motive or other conflicts of interest.
Accordingly, Sia’s consensus functionality will no longer be directly maintained by Nebulous. Instead, the Foundation will release and maintain an implementation of a "minimal Sia full node," comprising the Sia consensus algorithm and P2P networking code. The source code will be available in a public repository, and signed binaries will be published for each release.
Other parties may use this code to provide alternative full node software. For example, Nebulous may extend the minimal full node with wallet, renter, and host functionality. The source code of any such implementation may be submitted to the Foundation for review. If the code passes review, the Foundation will provide "endorsement signatures" for the commit hash used and for binaries compiled internally by the Foundation. Specifically, these signatures assert that the Foundation believes the software contains no consensus-breaking changes or other modifications to imported Foundation code. Endorsement signatures and Foundation-compiled binaries may be displayed and distributed by the receiving party, along with an appropriate disclaimer.
A minimal full node is not terribly useful on its own; the wallet, renter, host, and other extensions are what make Sia a proper developer platform. Currently, the only implementations of these extensions are maintained by Nebulous. The Foundation will contract Nebulous to ensure that these extensions continue to receive updates and enhancements. Later on, the Foundation intends to develop its own implementations of these extensions and others. As with the minimal node software, these extensions will be open source and available in public repositories for use by any Sia node software.
With the consensus code now managed by the Foundation, the task of implementing and orchestrating hardforks becomes its responsibility as well. When the Foundation determines that a hardfork is necessary (whether through internal discussion or via community petition), a formal proposal will be drafted and submitted for public review, during which arguments for and against the proposal may be submitted to a public repository. During this time, the hardfork code will be implemented, either by Foundation employees or by external contributors working closely with the Foundation. Once the implementation is finished, final arguments will be heard. The Foundation board will then vote whether to accept or reject the proposal, and announce their decision along with appropriate justification. Assuming the proposal was accepted, the Foundation will announce the block height at which the hardfork will activate, and will subsequently release source code and signed binaries that incorporate the hardfork code.
Regardless of the Foundation's decision, it is the community that ultimately determines whether a fork is accepted or rejected – nothing can change that. Foundation node software will never automatically update, so all forks must be explicitly adopted by users. Furthermore, the Foundation will provide replay and wipeout protection for its hard forks, protecting other chains from unintended or malicious reorgs. Similarly, the Foundation will ensure that any file contracts formed prior to a fork activation will continue to be honored on both chains until they expire.
Finally, the Foundation also intends to pursue scalability solutions for the Sia blockchain. In particular, work has already begun on an implementation of Utreexo, which will greatly reduce the space requirements of fully-validating nodes (allowing a full node to be run on a smartphone) while increasing throughput and decreasing initial sync time. A hardfork implementing Utreexo will be submitted to the community as per the process detailed above.
As this is the most important responsibility of the Foundation, it will receive a significant portion of the Foundation’s budget, primarily in the form of developer salaries and contracting agreements.

Support community services

We intend to allocate 25% of the Foundation Fund towards the community. This allocation will be held and disbursed in the form of siacoins, and will pay for grants, bounties, hackathons, and other community-driven endeavours.
Any community-run service, such as a Skynet portal, explorer or web wallet, may apply to have its costs covered by the Foundation. Upon approval, the Foundation will reimburse expenses incurred by the service, subject to the exact terms agreed to. The intent of these grants is not to provide a source of income, but rather to make such services "break even" for their operators, so that members of the community can enrich the Sia ecosystem without worrying about the impact on their own finances.

Ensure easy acquisition and storage of siacoins

Most users will acquire their siacoins via an exchange. The Foundation will provide support to Sia-compatible exchanges, and pursue relevant integrations at its discretion, such as Coinbase's new Rosetta standard. The Foundation may also release DEX software that enables trading cryptocurrencies without the need for a third party. (The Foundation itself will never operate as a money transmitter.)
Increasingly, users are storing their cryptocurrency on hardware wallets. The Foundation will maintain the existing Ledger Nano S integration, and pursue further integrations at its discretion.
Of course, all hardware wallets must be paired with software running on a computer or smartphone, so the Foundation will also develop and/or maintain client-side wallet software, including both full-node wallets and "lite" wallets. Community-operated wallet services, i.e. web wallets, may be funded via grants.
Like core software maintenance, this responsibility will be funded in the form of developer salaries and contracting agreements.

Protect the ecosystem

When it comes to cryptocurrency security, patching software vulnerabilities is table stakes; there are significant legal and social threats that we must be mindful of as well. As such, the Foundation will earmark a portion of its fund to defend the community from legal action. The Foundation will also safeguard the network from 51% attacks and other threats to network security by implementing softforks and/or hardforks where necessary.
The Foundation also intends to assist in the development of a new FOSS software license, and to solicit legal memos on various Sia-related matters, such as hosting in the United States and the EU.
In a broader sense, the establishment of the Foundation makes the ecosystem more robust by transferring core development to a more neutral entity. Thanks to its funding structure, the Foundation will be immune to various forms of pressure that for-profit companies are susceptible to.

Drive adoption of Sia

Although the overriding goal of the Foundation is to make Sia the best platform it can be, all that work will be in vain if no one uses the platform. There are a number of ways the Foundation can promote Sia and get it into the hands of potential users and developers.
In-person conferences are understandably far less popular now, but the Foundation can sponsor and/or participate in virtual conferences. (In-person conferences may be held in the future, permitting circumstances.) Similarly, the Foundation will provide prizes for hackathons, which may be organized by community members, Nebulous, or the Foundation itself. Lastly, partnerships with other companies in the cryptocurrency space—or the cloud storage space—are a great way to increase awareness of Sia. To handle these responsibilities, one of the early priorities of the Foundation will be to hire a marketing director.

Fund Management

The Foundation Fund will be controlled by a multisig address. Each member of the Foundation's board will control one of the signing keys, with the signature threshold to be determined once the final composition of the board is known. (This threshold may also be increased or decreased if the number of board members changes.) Additionally, one timelocked signing key will be controlled by David Vorick. This key will act as a “dead man’s switch,” to be used in the event of an emergency that prevents Foundation board members from reaching the signature threshold. The timelock ensures that this key cannot be used unless the Foundation fails to sign a transaction for several months.
On the 1st of each month, the Foundation will use its keys to transfer all siacoins in the Fund to two new addresses. The first address will be controlled by a high-security hot wallet, and will receive approximately one month's worth of Foundation expenditures. The second address, receiving the remaining siacoins, will be a modified version of the source address: specifically, it will increase the timelock on David Vorick's signing key by one month. Any other changes to the set of signing keys, such as the arrival or departure of board members, will be incorporated into this address as well.
The Foundation Fund is allocated in SC, but many of the Foundation's expenditures must be paid in USD or other fiat currency. Accordingly, the Foundation will convert, at its discretion, a portion of its monthly withdrawals to fiat currency. We expect this conversion to be primarily facilitated by private "OTC" sales to accredited investors. The Foundation currently has no plans to speculate in cryptocurrency or other assets.
Finally, it is important that the Foundation adds value to the Sia platform well in excess of the inflation introduced by the block subsidy. For this reason, the Foundation intends to provably burn, on a quarterly basis, any coins that it cannot allocate towards any justifiable expense. In other words, coins will be burned whenever doing so provides greater value to the platform than any other use. Furthermore, the Foundation will cap its SC treasury at 5% of the total supply, and will cap its USD treasury at 4 years’ worth of predicted expenses.
 
Addendum: Hardfork Timeline
We would like to see this proposal finalized and accepted by the community no later than September 30th. A new version of siad, implementing the hardfork, will be released no later than October 15th. The hardfork will activate at block 293220, which is expected to occur around 12pm EST on January 1st, 2021.
 
Addendum: Inflation specifics
The total supply of siacoins as of January 1st, 2021 will be approximately 45.243 GS. The initial subsidy of 1.57 GS thus increases the supply by 3.47%, and the total annual inflation in 2021 will be at most 10.4% (if zero coins are burned). In 2022, total annual inflation will be at most 6.28%, and will steadily decrease in subsequent years.
 

Conclusion

We see the establishment of the Foundation as an important step in the maturation of the Sia project. It provides the ecosystem with a sustainable source of funding that can be exclusively directed towards achieving Sia's ambitious goals. Compared to other projects with far deeper pockets, Sia has always punched above its weight; once we're on equal footing, there's no telling what we'll be able to achieve.
Nevertheless, we do not propose this change lightly, and have taken pains to ensure that the Foundation will act in accordance with the ideals that this community shares. It will operate transparently, keep inflation to a minimum, and respect the user's fundamental role in decentralized systems. We hope that everyone in the community will consider this proposal carefully, and look forward to a productive discussion.

About Ethereum mining pitfalls, risks, and threats

Bitcoin miners are massively switching to Ethereum. According to 8btc estimates, the payback period for a Bitcoin miner is 600 days, while for the same metric on Ether it only takes 200 days. But this goodness won’t last forever. Read about what threatens the development of Ethereum below.
Hardware and Filling – Halfway to Success
Experienced folks advise taking the most productive video cards, for example, the latest models from Nvidia and AMD. When choosing, pay attention to the amount of video memory (ideally from 2 GB), memory speed (with DDR 5 memory), bus width (better with a 256-bit bus), and cooling (basically there’s no competition to Radeon devices). Take Radeon RX 570, this 169 USD card produces 24-30 Mh/s, which is superb.
The Illusion of Stability
The entire multi-million community of Ether lovers trembled in early August when the Ethereum Classic network was subjected to several 51% attacks at once. In addition, in the first half of 2020 alone, over 5 attacks were carried out on popular DeFi platforms, including Balancer ($500,000 stolen) and bZx (17,500 ETH were stolen in total). Moreover, cybercriminals do not always use technical vulnerabilities, sometimes good old social engineering works.
Reduction of Reward
Ethereum developers have proposed to reduce the block mining reward by 75%. ConsenSys Managing Director John Leelik published the EIP-2878 proposal aimed at reducing inflation and preserving purchasing power. If supported, the reward will drop to 0.5 ETH.
The transition of ETH to ETH 2.0 (PoS)
We already wrote about this in the article "Problems of Ethereum Mining", and you can also watch the interview by Peter McCormack with the project founder Vitalik Buterin.
While the opportunity is still there, we offer everyone to get the most out of it and mine profitably. For example, take a closer look at the new CoinFLy ETH Pool, that nowadays offers more rewards than others, at least by 10%.
Profit That is Not Profit
A hidden and obvious problem is choosing the pool based on its profitability. If you only have a few capacities, then it is better to choose a pool that uses the PPS+ model, if you’ve got a lot of them, then a powerful pool with PPLNS is better. And if you’ve got so many capacities that there’s even enough for others, then you can also go SOLO, buddy. More details - here.

Microsoft patent 2020-060606 linking human brain to crypto payment system

Microsoft filed a patent 2020-060606 on June 20, 2019 for the link between the human body and the crypto payment system. It is a cryptocurrency mining system that uses human pulses such as brain waves and body heat to perform online tasks such as using search engines, chatbots, and reading ads. "A user can solve the arithmetically difficult problem unconsciously," says the patent.
In fact, this is a very brief description of a brain computer interface, which can read and write electromagnetic signals from the brain at such a finely meshed level that the brain literally becomes a biocomputer in a network. To understand that, please watch the video below and read on below. This is necessary so that you understand the current technological state of affairs.
Steve Hoffman - Brain Hacking & MindTech - Produced by DingDingTV
How cryptocurrency works The aim is that we are collectively hung in a hyve mind and it seems that what with crpyo-currency like Bitcoin still had to be done on energy-guzzling mining servers, can now be filled in by the “human bio-computer”.
The unique thing about blockchain payment systems was that as soon as you took a so-called wallet into the network, your computer formed a block in the network, where your computer receives a kind of calculation program that calculates the security key of a coin. All computers on the network must then come up with the same key as confirmation. If the entire network sees a transaction of a coin, all those keys are checked and if one is different, the transaction is illegal and rejected. That would create unhackable security.
The problem, however, is that Bitcoin mining requires a lot of computing power and that requires electricity. That's why Bitcoin mining ended up being one of the most energy-guzzling industries in the world. The Microsoft patent seems to aim at making this blockchain principle, which is not only very energy-guzzling, but also puts a heavy burden on the internet in terms of bandwidth (after all, all computers in the chain must always be checked for positive encryption), superfluous to make.
Simply put: Microsoft wants to use the human brain as a block in the blockchain. The 5G network will provide sufficient bandwidth to realize this.

Link digital ID, vaccination ID and social credit system:
The coronavirus pandemic provides the perfect alibi for the introduction of such a system. In concrete terms, this means that a score of your behavior (expressed in points) will initially be kept in the cloud. If you stick to the rules, you can take public transport or plane. If you don't follow the rules, your score will go down. The upcoming social distancing apps are a precursor to such a behavioral scoring system. After all, if you do not keep enough distance from potential infections, you have to quarantine at home. We also see China taking the lead there. Watch the video below and then read on.
Wuhan coronavirus covid-19 totalitarian UN propaganda?
Although Bill Gates officially retired from Microsoft's board this year, we can guess who the big driving force behind patent 2020-060606 is.
Of course, I need not point out to the attentive reader that we recognize here the Biblical number of the mark of the beast from the Bible book of Revelation: 666. It states that the time will come when no one will be able to buy or sell without to bear 'the beast'. This under the statement that this number is six hundred and sixty-six.
The same Bill Gates is behind the ID2020 initiative that wants to develop a digital ID for vaccination registration. If you combine such a digital ID hallmark with a digital passport (ID) and with patent 2020-060606, then you have completely enslaved people.

Revelation 13: 16-18
16: And it causes it to give a mark to all, small and great, and rich and poor, and free and servants, on their right hand or on their foreheads;
17: And that no one should buy or sell except he who has that mark, or the name of the beast, or the number of his name.
18: Here is wisdom: let him that have understanding count the number of the beast; for the number of a man is, and his number is six hundred sixty and six.

The "Official Gazette of the Kingdom of the Netherlands" announced on March 31, 2020 (“coincidentally”) change in law that allows a digital ID. Translated:
Kingdom Act of 6 March 2020 amending the Passport Act in connection with the introduction of electronic identification with a public identification means and the expansion of the basic register of travel documents.
We Willem-Alexander, by the grace of God, King of the Netherlands, Prince of Oranje-Nassau, etc. etc. etc.
All who will see or hear it read, salute! do to know:
Thus We have considered that it is desirable to amend the Passport Act in connection with the introduction of electronic identification with a public means and the extension of the basic register of travel documents;


The consequences:
So if we don't wake up in masses now and discover that we are witnessing a Psychological Operation that fully complies with the master script, then there is no escape. Then we cannot buy or sell anything if we do not meet all the requirements of the state. And to all, it really means all. Making a minor offense once has immediate consequences. Not cooperating with the vaccination obligation (think Bill Gates) will definitely mean the end of being able to travel and participate in society at all. You should consider the most basic things such as being able to buy food and drink.

We must step out of our programming and know that we are sovereign. Please read the article from the official journal above again. In it you see that you can fully rely on your consciousness sovereignty. You are sovereign by nature and no law can bind you to anything. It says "We Willem-Alexander, by the grace of God". Now let him prove "that grace of God".
Every law is signed by the king by the grace of God. There is no evidence whatsoever of this and so the law does not apply. The only problem is the fact that social systems have built up around that grace of God, to which many swear allegiance.
Do we sit back and relax until we are swallowed up by the system of "the internet of things" by the grace of God, or do we activate ourselves to concrete things? Concrete matters means that we have to switch from passive to active and discover who we are in potential and in essence.

Bitcoin Fullnode Install Guide for Dummies ;-)

Bitcoin Fullnode Install Guide for Dummies ;-)
Feel free to stop at Level 0 or Level 1, which is fine. More advanced configs are offered to those with more tech savvy. This guide, obviously assumes a Windows 10 install, but other OSes work fine, just find a different guide. BTW, the "For Dummies" is a callback to a set of "tech" books in the 90's intended to be as easy as possible. It is in jest and not intended to insult the reader. Finally, if you dislike the formatting, a well formatted copy can be found here
There is a fairly small subset of Bitcoin users that run a full node. I think the idea of running a full node has gotten a bad rap over the years since there is so much talk about running on a Raspberry Pi, or getting zippy SSDs. Although all of this can be fun, it is often not really required at all. Here are some ways to run a full node starting with the very simple. I'll get into more complex configs, but these are all optional.

Tech Skill Level: 0 (the basics)

  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
In many cases, thats it. If your running a new machine with a fairly good internet connection, 8 or 9 hours will be enough to complete the "Initial Block Download" (IBD). This may fill up your drive a bit, but again, on most new machines, 300 GB of space isn't that hard to come by.

Tech Skill Level: 1 (encrypted wallet)

One thing we left out in the level-0 exercise is encrypting your wallet. It's easy enough to do well, but a bit more difficult to do right. The main challenge is that humans generate really poor passwords. If you want a good password, the best way is to use something called "diceware". Basically, you just grab 4 or 5 dice and each throw of the dice represents a certain word on a special list. The throw {1,4,5,3,1} for example would be the word camping on the EFF-diceware-wordlist. So you repeat this a few times until you have a list of 8 or so words which becomes the passphrase you use to encrypt your wallet. Write it down, it is always hard to remember at first. So at level-1 your list becomes:
  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Choose Encrypt Wallet from the Settings menu
  5. Enter your 8 word (or so) passphrase generated using the Diceware method

Wallet Encryption Dialog

Tech Skill Level: 2 (enable pruning if needed)

Though I said "300 GB of space isn't hard to come by", some times it actually is. If space is an issue, a simple way to fix it is to tell bitcoin to simple take less space. This is called "pruning" and can take that number from 300 GB down to below 5 GB. If you can't find 5 GB, then you'll have to read ahead to level-4 to add USB storage. But the good news is, enabling pruning is pretty easy, we just add another step to our working list:
  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Do the wallet encryption steps here if you wish
  5. Choose Options from the Settings menu
  6. Choose Prune block storage to: and select the max size for the blocks to use
  7. Exit and restart the bitcoin application for the changes to take effect

Pruning Dialog
Note, even setting this to 1 GB will still leave you with about a 4.5 GB install. The blocks take up a lot of space, but the chainstate and other folders eat up at least 3.5 GB and they can't be pruned. Also, be aware, to disable pruning requires you to perform the entire IBD again. While pruned some other functions my be disabled as well, so just know that pruning does limit some functionality.

Tech Skill Level: 3 (verify the installer)

Although this is arguably something that should be done at level-0, some find the intricacies of comparing hash (thumbprint) values to be tedious and beyond the scope of a beginner. You will find these types of hash compares suggested quite often as a way to prevent running tainted programs. Programs are often tainted by bad disk or network performance, but most often, taint is malicious code inserted by viruses or malware. This is a way to guard yourself against those types of attacks.
What I cover here is a very basic comparison on the certificate, but a more thorough verification advised by mosts uses a program called Gpg4Win, and is beyond the scope of this beginners guide. But regardless, most users should strive to do this minimum level of validation.
  1. Download Bitcoin Core
  2. Launch the downloaded installer
  3. When prompted "Do you want to allow..." click Show more details
  4. In the details section select Show information about the publisher's certificate
  5. In the certificate window select the Details tab
  6. In the Details tab Subject should start with "CN = Bitcoin Core Code Signing Association"
  7. Ensure Thumbprint in Details reads ea27d3cefb3eb715ed214176a5d027e01ba1ee86
  8. If the checks pass, click OK to exit the certificate window and Yes to allow the installer to run.
  9. Launch the installed "Bitcoin Core" app and let it run overnight
  10. Do the wallet encryption steps here if you wish
  11. Do the optional pruning steps here if you wish

Certification Validation Windows
Note: The certificate used to sign the current Bitcoin installer is only valid from March 2020 to March 2021. After that point the thumbprint on the certificate will change. This is by design and intentional. If your reading this post after March 2021, then it is understood that the thumbprint has changed.

Tech Skill Level: 4 (use secondary storage)

We glossed over the "new machine with fairly good internet" part. Truth be known many people do not have fairly new machines, and find the IBD to take longer than the "over night" best wishes. For most people the slowdown is the disk access when calculating what is called chainstate. This requires fast random reads and writes to the disk. If you have an SSD disk, this will be no problem, but if you have a non-SSD "spinning" disk, random writes are always slow. Though an SSD will speed things up, they are pricey, so a nice middle ground may be a simple high-end USB key drive. You can get some with 10 to 15 MB/s random writes for $20 on Amazon. This is usually a order of magnitude faster than a "spinning" disk. And with pruning (see level-2), a small USB drive should be fine.
Once you decide on a drive, the tricky part will be to enable external storage. It requires editing a configuration file and adding a line. First, we want to create a directory on the key drive. You will need to determine the drive letter of your USB key drive. For the sake of this example, we will assume it is D:, but you must determine this yourself and correct the example. Once you know the drive letter, create a blank folder on the drive called Bitcoin. So for this example, creating Bitcoin on drive D: will create the path D:\Bitcoin. Once done, assuming that D: is your drive, here are the new steps including the edit of the configuration file:
  1. Download Bitcoin Core
  2. Launch the installer, verify it, then run it
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Do the wallet encryption steps here if you wish
  5. Do the optional pruning steps here if you wish
  6. Launch "Notepad" by typing "Notepad.exe" in the windows search bar then click Open
  7. Type the line datadir=D:\Bitcoin (depending on your drive letter) in the blank file
  8. Choose Save from the File menu in notepad
  9. Type %APPDATA%\Bitcoin\bitcoin.conf (note the percent signs) in the File name box
  10. Select All Files from the Save as type dropdown
  11. Click the Save button and overwrite the file if prompted
  12. Exit and restart the bitcoin application for the changes to take effect

Save As Dialog
Now that you've reached this level of technical expertise, there are many new configuration options that you can begin to modify if you wish. Most configuration data is contained in the bitcoin.conf file and learning how to maintain it is a key step for a node operator.

Tech Skill Level: 5 (all other customizations)

Here's a short list of various things you can ADD to your bitcoin.conf file. You generally just add a new line for each configuration settings.
  • addresstype=bech32
  • changetype=bech32
The addresstype / changetype allows your wallet to use the native-segwit (bech32) format. This is the most efficient and inexpensive way to spend bitcoin, and is a recommended configuration. The default uses something called p2sh-segwit which is more compatible with older wallets, but more expensive to spend.
  • minrelaytxfee=0.00000011
Changing the minrelaytxfee setting allows you to help propagate lower fee transactions. It will require more memory but TXN memory is capped at 300 MB by default anyways, so if you have enough memory, it is a good setting to choose.
  • dbcache=2048
The dbcache setting controls how many MB of memory the program will use for the chainstate database. Since this is a key bottleneck in the IBD, setting this value high (2048 MB) will greatly speed up the IBD, assuming you have the memory to spare
  • blocksdir=C:\Bitcoin
  • datadir=D:\Bitcoin
In level-4 we discussed moving the datadir to a fast external storage, but the majority of the space used for bitcoin is the blocks directory (blocksdir). Although you should always use for fastest storage for datadir, you are free to use slow storage for blocksdir. So if you only want to consume a small amount of your SSD (assumed D:) then you can keep your blocks on your slow "spinning" drive.
  • upnp=1
One of the harder challenges you may face running a node, is to get incoming connections. If you are lucky, you may find that your firewall and network HW support the uPnP protocol. If they do, this setting will allow bitcoin to configure uPnP to allow incoming connections to your node. Other methods exist to make your node reachable, but they are well beyond the scope of this guide.

Announcement on Preparations of Coming BCH Fork & Launch of Forked Coins Futures Markets

Announcement on Preparations of Coming BCH Fork & Launch of Forked Coins Futures Markets

https://preview.redd.it/etcgo7f7l0p51.jpg?width=900&format=pjpg&auto=webp&s=3fdc41c9077c5d3461e29829c2e76de3853e4915
Dear CoinEx users,
The Bitcoin Cash (BCH) network will undergo a semi-annual hard fork upgrade on November 15 as scheduled. The Bitcoin ABC team plans to introduce new Coinbase rules in this upgrade, and allocate 8% of block rewards to developers to support the infrastructure construction of BCH, namely Infrastructure Funding Plan (IFP). This Plan has aroused hot discussions and controversies in the BCH community. Among them, the Bitcoin Cash Node development team launched BCHN full node that is incompatible with the BCH full node developed by the BitCoin ABC team, and the BCHN full node implementation removed the Coinbase rules and won support from most miners.
Since the Bitcoin ABC full node implementation is widely used and recognized, it is very likely that BCH will be split into two chains during the upgrade. One of which will inherit the name of BCH and the other will adopt a brand new name. If a fork occurs, all BCH holders can get two cryptocurrencies at a 1:1 ratio.
Unlike previous forks, this potential fork may be unable to continue due to lack of hashrate for a certain chain, or it possibly bring about two chains but not knowing which chain will use the name of BCH. More complexly, this fork lacks a transaction replay protection mechanism, which may result in considerable chaos and users’ asset loss.
CoinEx is a strong proponent of the BCH ecosystem, supporting trading markets with BCH as the pricing coin. To provide users with better services, we are going to launch futures markets of BCH forked coins on September 24, 2020. The details are as follows:
  1. Before the official fork on November 15, users can convert BCH into BCHA and BCHN at a 1:1 ratio. BCHA represents the Bitcoin ABC chain after the fork while BCHN represents the Bitcoin Cash Node chain. Also, users can re-convert these two forked coins into BCH at the same ratio before the fork. We will support BCHA/BCH and BCHN/BCH markets soon, and more markets later if needed.
  2. If BCH forks into two chains on November 15, we will appoint the chain with the highest price at the last moment before the fork as BCH. Users who hold the forked coin of that chain can obtain BCH at a 1:1 ratio, and BCH holders can get two different coins at the same ratio. In the future, we will re-adjust the naming rules based on the community consensus.
  3. If Bitcoin Cash does not fork on November 15, then whichever chain wins will inherit BCH. At the same time, we will delist the forked coin of the other chain. Therefore, please be aware of investment risks.
Opening Time
  1. Call Auction 3:00-11:50 September 24, 2020 (UTC)Orders can be placed and cancelled 11:50-12:00 September 24, 2020 (UTC) Orders can be placed but cannot be cancelled
  2. Trading 12:00 September 24, 2020 (UTC)
Risk Warning:Since BCH fork owns great uncertainty, trading or investing in forked coins is risky. Without support of miners, a chain may fail to survive and all related coins will be in vain. Please be note that CoinEx will not promise for the future values of any forked coins!

Minimum Viable Issuance - Why Ethereum’s lack of a hard cap on ETH issuance is a good thing.

This post will explain how the argument used by the average Bitcoin maximalist, thinking that they have found Ethereum’s achilles heel when talking about issuance is actually highlighting one of Ethereum’s strong points and one of the main threats to the longevity of the Bitcoin network.
So first let’s answer the question which I know many people have about Ethereum:

What is Ethereum’s ETH issuance schedule?

Ethereum has an issuance policy of Minimum Viable Issuance. So what does this mean exactly? It means that the issuance of ETH will be as low as possible while also maintaining a sufficient budget to pay miners (and soon to be stakers) to keep the network secure. For example, if ETH issuance was halved, miners would drop off the network and stop mining as it is no longer profitable for them to mine. As a result, the network would be less secure as it would cost less money for an attacker to control 51% of the hash power and attack the network. This means that the Ethereum community plans to change ETH issuance as time goes on to maintain a reasonable security budget which will keep the network secure but will also keep inflation in check. We have done this twice in the past with EIP-649 and EIP-1234 which reduced block rewards from 5 ETH per block to 3 ETH and from 3 ETH to 2 ETH respectively. I previously made a graph of ETH issuance over time here: https://redd.it/it8ce7
So while Ethereum doesn’t have a strictly defined issuance schedule, the community will reject any proposals which either put the security of the network at risk such as the recent EIP-2878, or we will reject proposals which will lead to excessive network security and therefore an unnecessarily high inflation rate (or we will accept proposals which reduce issuance after price rises and therefore the security budget rises). This means that when Bitcoiners accuse the Ethereum Foundation of being no better than a central bank because they can “print more Ether”, this is completely untrue. Any proposals made by the EF which would increase issuance unnecessarily would be rejected by the community in the same way that a proposal to increase the supply of Bitcoin from 21 million to 22 million would be rejected. There is a social contract around both Bitcoin’s and Ethereum’s issuance schedules. Any networks or proposals which break the social contracts of 21 million Bitcoins and minimal viable issuance of Ether would be a breach of these contracts and the new proposed network would be labeled by the community as illegitimate and the original network would live on.

So why is minimum viable issuance better than a hard cap?

Minimum viable issuance is better than a hard cap because it puts the most important part of the network first - the security. MVI ensures that the Ethereum network will always have a security budget which keeps the cost of a 51% attack impractically high. Bitcoin on the other hand, halves its security budget every 4 years until eventually only the transaction fees pay for network security. This means that every 4 years, the amount of money paying for network security halves until eventually, the value of attacking the network becomes greater than the security budget and someone performs a 51% attack (technically the security budget only halves if terms of BTC not in dollars. However, even if the price of Bitcoin more than doubles in the time that the security budget halves, the ratio of security budget to value secured on the network still halves, doubling the financial viability of performing a network attack). The strategy to pay for the security budget once Bitcoin issuance stops is for transaction fees to secure the network since transaction fees are paid to miners. Not only does this have its own security problems which I won’t detail here, but unless Bitcoin scales on layer 1 (layer 2 scaling solutions have their own security mechanisms separate from L1), then fees would have to cost well in the thousands of dollars to secure a trillion dollar market cap Bitcoin that is secured by nothing but fees. If Bitcoin maximalists want a 10 trillion or 100 trillion dollar market cap then expect fees to go up another 10 or 100 times from there.
Ethereum on the other hand, will be able to keep its network secure with approximately 1-2% annual issuance being paid to stakers under ETH 2.0. This is because not all of the network will be staking, so if 33 million of the approximately 110 million Ether in existence stakes under ETH 2.0, then paying this 33 million Ether 6% a year (a very decent yield!) would cost just under 2 million ETH per year which would equate to less than 2% annual ETH inflation. This is also before considering EIP-1559 which will burn a portion of transaction fees which will counter the effect of this inflation and potentially even make ETH deflationary if the sum of all burned transaction fees are greater than the annual inflation. Also, under ETH 2.0, an attacker performing a 51% attack would get his funds slashed (they would lose their funds) if they attack the network, meaning that they can only perform a 51% attack once. However, in Bitcoin, anyone who controls 51% of the mining hash power could perform multiple 51% attacks without losing everything like they could in ETH 2.0.
So in conclusion, while Ethereum doesn’t have the guaranteed anti-inflation security of a hard cap, it does have the guarantee of always paying it’s miners (or stakers under ETH 2.0) enough to keep the network secure. In contrast, while Bitcoin’s social contract may guarantee a hard cap of 21 million, it cannot simultaneously guarantee network security in the long run. Eventually, its users will have to decide if they want a secure network with more than 21 million coins or a tax to pay for security or an insecure network with super high fees and a hard cap of 21 million Bitcoin.
Disclaimer: The details I covered around 51% attacks and network security are simplified. I am not an expert in this field and things are a lot more nuanced than I laid out in my simplifications above.

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.
