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.

vectorbt - blazingly fast backtesting and interactive data analysis for quants

I want to share with you a tool that I was continuously developing during the last couple of months.
https://github.com/polakowo/vectorbt

As a data scientist, when I first started flirting with quant trading, I quickly realized that there is a shortage of Python packages that can actually enable me to iterate over a long list of possible strategies and hyper-parameters quickly. Most open-source backtesting libraries are very evolved in terms of functionality, but simply lack speed. Questions like "Which strategy is better: X or Y?" require fast computation and transformation of data. This not only prolongs your lifecycle of designing strategies, but is dangerous after all: limited number of tests is similar to a tunnel vision - it prevents you from seeing the bigger picture and makes you dive into the market blindly.
After trying tweaking pandas, multiprocessing, and even evaluating my strategies on a cluster with Spark, I finally found myself using Numba - a Python library that can compile slow Python code to be run at native machine code speed. And since there were no packages in the Python ecosystem that could even closely match the speed of my own backtests, I made vectorbt.
vectorbt combines pandas, NumPy and Numba sauce to obtain orders-of-magnitude speedup over other libraries. It builds upon the idea that each instance of a trading strategy can be represented in a vectorized form, so multiple strategy instances can be packed into a single multi-dimensional array. In this form, they can processed in a highly efficient manner and compared easily. It also integrates Plotly and ipywidgets to display complex charts and dashboards akin to Tableau right in the Jupyter notebook. You can find basic examples and explanations in the documentation.

Below is an example of doing in total 67,032 tests on three different timeframes of Bitcoin price history to explore how performance of a MACD strategy depends upon various combinations of fast, slow and signal windows:
import vectorbt as vbt import numpy as np import yfinance as yf from itertools import combinations, product # Fetch daily price of Bitcoin price = yf.Ticker("BTC-USD").history(period="max")['Close'] price = price.vbt.split_into_ranges(n=3) # Define hyper-parameter space # 49 fast x 49 slow x 19 signal fast_windows, slow_windows, signal_windows = vbt.indicators.create_param_combs( (product, (combinations, np.arange(2, 51, 1), 2), np.arange(2, 21, 1))) # Run MACD indicator macd_ind = vbt.MACD.from_params( price, fast_window=fast_windows, slow_window=slow_windows, signal_window=signal_windows, hide_params=['macd_ewm', 'signal_ewm'] ) # Long when MACD is above zero AND signal entries = macd_ind.macd_above(0) & macd_ind.macd_above(macd_ind.signal) # Short when MACD is below zero OR signal exits = macd_ind.macd_below(0) | macd_ind.macd_below(macd_ind.signal) # Build portfolio portfolio = vbt.Portfolio.from_signals( price.vbt.tile(len(fast_windows)), entries, exits, fees=0.001, freq='1D') # Draw all window combinations as a 3D volume fig = portfolio.total_return.vbt.volume( x_level='macd_fast_window', y_level='macd_slow_window', z_level='macd_signal_window', slider_level='range_start', template='plotly_dark', trace_kwargs=dict( colorscale='Viridis', colorbar=dict( title='Total return', tickformat='%' ) ) ) fig.show() 

https://reddit.com/link/hxl6bn/video/180sxqa8mzc51/player
From signal generation to data visualization, the example above needs roughly a minute to run.

vectorbt let's you
The current implementation has limitations though:

If it sounds cool enough, try it out! I would love if you'd give me some feedback and contribute to it at some point, as the codebase has grown very fast. Cheers.

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.

RiB Newsletter #15 – Turbofish in the Blocksea

Rust blockchain development continued at its typical blistering pace, and again it's impossible to follow everything going on.
This month we see continued advancement in zero-knowledge computing, an obvious focus from the entire blockchain industry on the DeFi phenomenon, and some new hackathons with opportunities for Rust developers.
Every month seems to bring advancements in zero-knowledge proofs, and new implementations in Rust. It is a research area that will probably impact the general computing industry eventually, and one where the blockchain industry is leading the way, and one where Rust has a huge foothold. Even projects that are not written in Rust we see implementing their zero-knowledge cryptography in Rust. But this stuff is extremely technical, and improving at a rapid pace. We fear we will never understand it.
There are several Rust blockchains now in development that are built around zero-knowledge VMs, whose smart contracts create zero-knowledge proofs:
These are networks that support nearly arbitrary computation over secret inputs. Like programable Zcash.
Speaking of Zcash, the zkSNARK pioneers announced their next-generation zero-knowledge proof system, called Halo 2, which uses a new zkSNARK construction, PLONK.
Two projects built on Rust blockchains launched this month: Serum, a decentralized exchange built on Solana; and Flux, a prediction market built on NEAR. Next month Secret Network launches their mainnet.
Finally, Mozilla laid off all but one of its full-time Rust employees. There are a few other people left at Mozilla who actively contribute to Rust as part of their role in Firefox, but this mostly ends Mozilla's commitment to Rust's development.
There's no need to worry though. Rust was designed to outlive Mozilla's withdrawal, and the project will continue nearly unaffected.

Project Spotlight

Each month we like to shine a light on a notable Rust blockchain project. This month that project is…
Fluence.
This is a blockchain with built-in software license management. We’re excited about this because license management is a rare non-currency use case for blockchains that makes a lot of sense. While we might expect to see more blockchain platforms devoted solely to digital licensing, fluence is actually a complete distributed computing platform, with a unique vision about using license management to generate profit from open source software.

My thoughts

I wasn’t active during this last hack on Reddit and the hack on the servers,but I have to say this hack is not made by a rocket scientist!!!
First for cracking the password of the accounts u can use Jack the Ripper or even more advanced software can be found in the dark web with a cost of literally some cents in bitcoin.
For hacking the servers u can use a built-in app in Kali Linux that find vulnerabilities on the web but as with the password cracker more advanced can be found but as a built in app it is very reliable.
Now with the vulnerabilities found the hacker can use other Linux app that come bundled with Kali or get some open source from Github and I have to say there’s a lot of them out there .
I can’t blame Dygn about the security of the servers till I see the complete number of vulnerabilities in there .
Keep strong Reddit!!

Why I think Ren is a game-changer for decentralized finance.

I'm Ken the author of The Weekly Coin newsletter, where every week I highlight high potential lower cap cryptocurrency projects one might have overlooked, the projects listed beyond the first page of CoinMarketCap. The Weekly Coin is merely a jumping-off point for you to do your own research.
If you're interested you can sign up for The Weekly Coin here. No ads, no spam, just the results of my research.
This week in The Weekly Coin we’re highlighting Ren. Ren currently lands on the 77th slot on CoinMarketCap. Yea, it's not hidden in the realms of the 2nd CMC pages and beyond. But, after researching this coin, I think it's a game-changer for DeFi and well, the cryptocurrency world as a whole. Also important to note is that I'm not invested in Ren, no one paid me to write this, and of course, I'm not a financial adviser. 😁
TL;DR
Ren allows the free movement of value between all blockchains and transfer of tokens in zero-knowledge. Unlocking new liquidity and resources to power a new wave of value in the open finance movement. With Ren all decentralized applications can run in secret, preserving the privacy of all users and data. (Renproject.io)

What is Ren?

Ren had humble beginnings as a project called Republic Protocol. Republic Protocol launched in 2017 and had their ICO on February 3, 2018. The platform focused on providing decentralized dark pools. A dark pool is a term used in traditional finance for anonymous over-the-counter (OTC) order books without moving the market (more on dark pools here). Republic Protocol's decentralized dark pools were specially designed to combat OTC trading which is known for their high fees and also to help increase institutional money flow into crypto. The technology behind these decentralized dark pools is called RenVM.
💡 Institutional investors want to get in the game but are staying on the sidelines until crypto has matured and risk is low.
RenVM turned out to be the perfect solution for interoperability between blockchains. This is because in a decentralized dark pool blockchains need to see each other. Republic Protocol then saw how massive this opportunity was and rebranded to Ren.
Ren is the evolution of the technology that underpins RepublicProtocol, in its most useful and general form. It becomes something much bigger than Republic Protocol and will empower developers to build decentralized and trustless applications, with a distinct focus on financial applications. Using our own newly developed secure multiparty computation protocol, all DeFi applications will have access to interoperable liquidity and run in complete secrecy. (Ren —The Evolution of a Protocol)
💡 To dumb it down a bit, Ren is the organization's name, REN is the ERC-20 based token, and RenVM is Ren’s core product.

Token use

To put simply, for now, the REN token is used as a work token. The token is used as a bond to run a Darknode. What is a Darknode?
RenVM is replicated over thousands of machines that work together to power it, contributing their network bandwidth, their computational power, and their storage capacity. These machines are known as Darknodes.
Darknodes communicate with other Darknodes around the world to keep RenVM running. Without them, there is no virtual machine upon which Ren can exist. RenVM uses Byzantine Fault Tolerant consensus algorithms and secure multiparty computations so that Darknodes can be operated by anyone without needing to trust them. This is what makes RenVM — and by extension, Ren itself — decentralized, trustless, and private. (Ren Documentation)
Ok so now we know what a Darknode is but what is REN Tokens used for?
The decentralized network of Darknodes is permissionless, but to prevent the forging of a large number of identities a good behavior a bond of 100,000 REN tokens is required in order to register and run a Darknode. This prevents malicious adversaries from running an unbounded number of Darknodes and overwhelming the network with misbehaving Darknodes. (Ren Documentation)
As stated, to run a Darknode you'll need 100,000 REN. You can liken this to Proof of Stake (PoS) systems in which you stake a certain currency to encourage honest behavior in block production. The benefits of running a Darknode is you will be paid transaction fees. Initially, the fees were paid in REN tokens but now Darknode operators can be paid other cryptocurrencies such as BTC, ETH, ZEC, and other ERC20 tokens.
The REN token is required to run a Darknode but the tokens are not required to use RenVM. Let’s say someone wants to acquire BAT with their BTC using a RenVM enabled DEX; where would they get the REN to preform the transaction? A centralized exchange? That defeats the purpose. A decentralized exchange? They'd need ETH or an ERC-20 token. Idk if you've used Uniswap before but you don't need an Uniswap token to swap, send, or pool. Using the RenVM is similar, you don't need to use the REN token.

Why I think Ren is a game-changer

With around 900 million dollars locked up in DeFi it's no secret that DeFi is booming right now. Go to DeFi Pulse and take a look at which chains all the DeFi applications are being built on, go on. What you'll see is every application is built on Ethereum.
Ethereum has a smart contract platform for business logic, whereas Bitcoin doesn't. You can loan and mint something like DAI without trusting an intermediary, all of this is done on Ethereum. But what if you wanted to use Bitcoin on a DEX to get DAI? Another problem is Ethereum doesn't know Bitcoin exists and vice versa. Ren fixes this. You can trade Bitcoin on a DEX like Uniswap against Ethereum or mint Dai with Bitcoin. Check out this Github repo outlining how to enable BTC and ZEC in Uniswap. As a developer of a decentralized exchange myself, I think this is huge. 🔥
Well you might be saying "We have wrapped Bitcoin", well wBTC isn't actually Bitcoin, it's more like an IOU token or a proxy. An imposter!
Well, you might be saying "We have Atomic Swaps", well Atomic Swaps are slow and a bit annoying and complex. The two parties looking to transact have to send the transaction, wait for confirmation, then send a transaction and then finally wait for a confirmation. What if the internet goes down for a person in the party? What happens if the market gets flooded?
With the RenVM it's only one transaction, it's quick, easy, and you send actual Bitcoin. There is also no need for specialized software. The RenVM takes care of it all. Check out these examples of RenVM in action.
https://youtu.be/7nqTpNt4BD0
https://youtu.be/FfQ5gBbhzlc
Also, check out Ren's Chaos Dex where you can swap SAI (DAI) for BTC or ZEC. For more information on Chaos Dex go here. Idk about you but this stuff blows my mind.
Ren is in talks with dApps in the DeFi space making sure RenVM is aligned with their platforms. There also is documentation and integrations for you to build on RenVM. Ren also has been making great strides recently in inter-blockchain liquidity by recently announcing The Ren Alliance.
The Ren Alliance is a consortium of DeFi companies and/or projects that are helping secure, develop, and utilize RenVM. (Introducing the Ren Alliance)
Also, Important to note is Ren has top tier investors in the likes of FGB Capital, Polychain Capital, and Kenetic Capital. But its headlining investor is crypto giant Huobi, which this past July launched its Huobi Cloud platform for OTC desks. Work is being done and a lot of progress is being made.

Why do we even need Interoperability?

I'm gonna yank the text straight from an article by Capgemini which explains the benefits of interoperability quite nicely.
The blockchain-based networks are being built to offer specific capabilities such as making payments, storing and trading assets and others. However, these capabilities are being offered in isolation where these networks don’t talk to each other and cannot share data. Existing centralized systems have evolved to offer the same capabilities in a more integrated way where these systems are able to run end to end transactions seamlessly making it easier for users.
If blockchain-based networks have to make a strong case for their adoption, they have to be able to work with each other and offer this seamless integration of capabilities to their users.
Strong interoperability would give users a much more useful, user-friendly experience. With this interoperability, users will be able to experience the seamless integration of capabilities being offered by the blockchain-based networks. If we have to hypothesize an example, it would look something like this – User will be able to tokenize the asset (e.g. artwork) over Ethereum based DApp, will be able to transfer the tokenized asset to another address over Cardano, and pay any corresponding transaction fees over the bitcoin network. (Capgemini)
The cryptocurrency space is pretty fragmented at times. There also is a bunch of tribalism. It can be a bit annoying. One coin makes massive efforts over here and another coin is making massive efforts over there. What if we could combine the efforts into one big force of nature? I think we can take over the world. Which, would be, huge.
Idk about y’all but I’m gonna be following the Ren team to see what they come up with. The impact this coin can have could be massive. I think Ren is definitely a coin you should look at.

In my next newsletter I plan to highlight Ren. Anything I should add or remove?

Hey guys I'm the author of a short weekly newsletter called The Weekly Coin where I highlight high potential lower cap projects. Next week I plan to highlight Ren. I want to consult the community to see if I missed out or should add any details.
(If you're interested you can check out The Weekly Coin here, but no pressure at all.)
Here is the newsletter.

Remember when smart phones had different operating systems? I’m talking about early cell phone days, the days of the flip phone. The Motorola Razr V3, Sony Ericsson K300, and Samsung SGH-D500 all had its their own proprietary OS. It was all a jumbled mess. The cell phone industry couldn’t move together as one.
Nowadays there is much less variety to contend with. Operating systems have dwindled down to mainly just iOS and Android and as a result cell phones have advanced greatly.
Blockchains today operate just like the operating systems of those ancient dark times. Ethereum has no clue Bitcoin exist, Bitcoin has no clue ZCash exists and vice versa. The communication between blockchain networks is called interoperability and Ren is doing just that.
Ren is…
"The first and only open protocol that provides access to inter-blockchain liquidity for all decentralized applications. Bringing BTC, BCH and ZEC to your Ethereum dApp." (renproject.io)
Along with interoperablity Ren focuses heavily on privacy for true decentralization.
"Trustless privacy and interoperability are absolutely necessary for achieving truly decentralized applications that are secure, usable, and liquid." (docs.renproject.io/ren)
Overview
- CoinMarketCap Rank: 82
- Current Price: $0.026782
- Market Cap: $52,693,330
- Max Supply: 1,000,000,000 REN
- Where to buy REN: Binance, Huobi, Kyber Network, Uniswap
- Development Frequency: On Github the Ren organization has a number of active repositories that help developers integrate Ren into their own dApps even providing a TypeScript example as well as documentation on getting started. As a developer this is a beauty to see.
Ren has been making great strides recently in inter-blockchain liquidity by recently announcing The Ren Alliance.
"The Ren Alliance is a consortium of DeFi companies and/or projects that are helping secure, develop, and utilize RenVM." (Introducing the Ren Alliance)
Ren is putting in work and a lot of it. There needs to be a standardized way of communication so this space can move together more concurrently or at the very least pool resources together. I think Ren is definitely a coin you should take a look at.

Let me know what you think!

ngPost v4.2 : monitoring for the HMI :)

Hi,
As many people were asking for this, I've implemented the Monitoring for the HMI :)
ngPost v4.2
So there is a new "Monitor Folder" in the Auto Posting Tab.
Monitoring will only post new files, not current ones. For current one, press the Scan Button, then Generate Posts.
I've added the same color system than for the Quick Post: each new incoming file in the Monitoring folder will arrive in dark blue as Pending. When it is Posting, it became gold, once posted, either green red or yellow depending on success.
I've also added the "delete files once posted (only for Monitoring)" option, that does what it says ;)
Few fixes have also been added to this release: #################################################### ### Release: ngPost v4.2 ### ### date: 2020/02/02 ### ####################################################
- Monitoring for the HMI \o/ (only one folder although you could use several in CMD)
- correct crash when stopping CMD during rar or par2
- add nzbPath to the HMI. (also inputDir)
- new config MONITOR_NZB_FOLDERS (request/issue #15)
- fix Article retry when error on connection (the current one was previously skipped)
- limit characters allowed in nzb name
- fix rar command on windows for shared folder

Hope you'll enjoy it!
Please don't forget to make a contribution (paypal or bitcoin) if you'd like to reward the work and/or would like more features.
For those who didn't see it, here is a description of the v3.1 with the GUI features and here for the 4.1 with the monitoring in command line.
Releases are available here on github for Linux 64bit, MacOS, Windows (32 and 64bit) and Raspbian for Raspberry PI (amrhf).

Why did I build AmputatorBot?

Why did I build AmputatorBot?

This thread was automatically archived (RIP). Check out the new one here.

Update #3: www.AmputatorBot.com is now live!
Update #2: AmputatorBot is now open source!
Update #1: You can now summon AmputatorBot!

Why AMP is bad for everyone

TL;DR: Google’s AMP is a major threat to the Open Web and your privacy.
AMP means “Accelerated Mobile Pages” and is a framework designed to make websites faster. In many cases, it does exactly that. However, it comes at a high price.
Google's AMP is a major threat to the Open Web. AMP was developed in secret alongside some major news organisations. By the time it was released, Google’s spec and infrastructure were basically settled and non-negotiable. And now Google is prioritizing AMP pages in their search results and they only allow AMP pages to appear on their news carousel. This forces more and more organisations to implement AMP, thereby increasing the power of an already huge and monopolistic company.
And while Google is increasing their control over the internet, you’re losing control over your privacy. Google’s entire business model is about collecting as much personal data as possible. AMP is just another tool to do so. As described in Google’s Support article:
When you use the Google AMP Viewer, Google and the publisher that made the AMP page may each collect data about you.
To protect the Open Web and your privacy, u/AmputatorBot provides the direct link (bypassing Google).

And now, for the nerds among us, some rather technical stuff:

Automatic working subreddits

u/amputatorbot currently works automatically with a select number of subreddits: amputatorbot, audio, chrome, degoogle, economy, europe, europrivacy, firefox, gaming, programming, robotics, security, seo, tech, technology, test, upliftingnews and worldnews.
You can summon the bot almost everywhere else by typing: u/AmputatorBot, more info here.
Hit me up with questions or suggestions and I will try to respond ASAP!

Non-working subreddits

AmputatorBot doesn't work in these subreddits: android, beer, bitcoin, books, conservative, CryptoCurrency, economics, ELI5, flying, Futurology, gadgets, google, history, korea, kitchener, movies, nottheonion, news, PoliticalDiscussion, politics, popheads, todayilearned, truecrimediscussion and worldpolitics for diverse reasons. Summoning the bot will not work there either.

Www.AmputatorBot.com

Remove AMP in just one click with www.AmputatorBot.com!
I've made quick and free online version of AmputatorBot over at www.AmputatorBot.com. It's really easy, just paste an AMP URL in the input box, click the button and that's all! See the announcement post here.
A quick demo of www.AmputatorBot.com

Browser extension

The 'Redirect AMP to HTML' extension by Daniel Aleksandersen enables users to choose to opt-out of using Accelerated Mobile Pages (AMP) and choose to use the standard web instead. In other words, it does the same thing as u/AmputatorBot, but automatically and it works great. 10/10 would recommand!

Changelog

Check out the changelog here. Latest major update: 16/12/2019

Opt-out & opt-back-in

The bot works automatically in the subreddits mentioned above and manually using mentions.
Opt out: If you want to prevent the bot from replying to your comments and submissions, click here to opt out.
Opt back in: Did you opt-out and regret it? Click here to opt back in.

Support the project

AmputatorBot is a really important project for me and I want to spend as much time and resources into accomplishing it's goal: to make people aware of the dark side of AMP and to give people a choice. You can support the project in a couple of ways:

Donate to help me cover some of the costs
If you have some spare change laying around, you could make a small donation to keep the servers running. You can donate via PayPal by clicking on this link: https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=EU6ZFKTVT9VH2. It costs €8.26 per month to host the bot 24/7. You can fill in any amount of money, but don't feel obligated to donate much, I'm just trying to cover the costs.

Give feedback and contribute (AmputatorBot is open-source!)
If you have some spare time laying around, please give me feedback! You can:

Summon the bot
Have you spotted an AMP link in a submitted page or comment? Mention u/AmputatorBot in a reply and I'll do my best to share the direct source (just remember that this won't work on the non-working subreddits). More info about this feature can be found here.

Thanks for the tremendous support you've given me and u/AmputatorBot <3

For devs and advanced users that are still in the dark: Read this to get redpilled about why Bitcoin (SV) is the real Bitcoin

This post by cryptorebel is a great intro for newbies. Here is a continuation for a technical audience. I'll be making edits for readability and maybe even add more content.
The short explanation of why BSV is the real Bitcoin is that it implements the original L1 scripting language, and removes hacks like p2sh. It also removes the block size limit, and yes that leads to a small number of huge nodes. It might not be the system you wanted. Nodes are miners.
The key thing to understand about the UTXO architecture is that it is maximally "sharded" by default. Logically dependent transactions may require linear span to construct, but they can be validated in sublinear span (actually polylogarithmic expected span). Constructing dependent transactions happens out-of-band in any case.
The fact that transactions in a block are merkelized is an obvious sign that Bitcoin was designed for big blocks. But merkle trees are only half the story. UTXOs are essentially hash-addressed stateful continuation snapshots which can also be "merged" (validated) in a tree.
I won't even bother talking about how broken Lightning Network is. Of all the L2 scaling solutions that could have been used with small block sizes, it's almost unbelievable how many bad choices they've made. We should be kind to them and assume it was deliberate sabotage rather than insulting their intelligence.
Segwit is also outside the scope of this post.
However I will briefly hate on p2sh. Imagine seeing a stunted L1 script language, and deciding that the best way to implement multisigs was a soft-fork patch in the form of p2sh. If the intent was truly backwards-compatability with old clients, then by that logic all segwit and p2sh addresses are supposed to only be protected by transient rules outside of the protocol. Explain that to your custody clients.
As far as Bitcoin Cash goes, I was in the camp of "there's still time to save BCH" until not too long ago. Unfortunately the galaxy brains behind BCH have doubled down on their mistakes. Again, it is kinder to assume deliberate sabotage. (As an aside, the fact that they didn't embrace the name "bcash" when it was used to attack them shows how unprepared they are when the real psyops start to hit. Or, again, that the saboteurs controlled the entire back-and-forth.)
The one useful thing that came out of BCH is some progress on L1 apps based on covenants, but the issue is that they are not taking care to ensure every change maintains the asymptotic validation complexity of bitcoin's UTXO.
Besides that, The BCH devs missed something big. So did I.
It's possible to load the entire transaction onto the stack without adding any new opcodes. Read this post for a quick intro on how transaction meta-evaluation leads to stateful smart contract capabilities. Note that it was written before I understood how it was possible in Bitcoin, but the concept is the same. I've switching to developing a language that abstracts this behavior and compiles to bitcoin's L1. (Please don't "told you so" at me if you just blindly trusted nChain but still can't explain how it's done.)
It is true that this does not allow exactly the same class of L1 applications as Ethereum. It only allows those than can be made parallel, those that can delegate synchronization to "userspace". It forces you to be scalable, to process bottlenecks out-of-band at a per-application level.
Now, some of the more diehard supporters might say that Satoshi knew this was possible and meant for it to be this way, but honestly I don't believe that. nChain says they discovered the technique 'several years ago'. OP_PUSH_TX would have been a very simple opcode to include, and it does not change any aspect of validation in any way. The entire transaction is already in the L1 evaluation context for the purpose of checksig, it truly changes nothing.
But here's the thing: it doesn't matter if this was a happy accident. What matters is that it works. It is far more important to keep the continuity of the original protocol spec than to keep making optimizations at the protocol level. In a concatenative language like bitcoin script, optimized clients can recognize "checksig trick phrases" regardless of their location in the script, and treat them like a simple opcode. Script size is not a constraint when you allow the protocol to scale as designed. Think of it as precompiles in EVM.
Now let's address Ethereum. V. Buterin recently wrote a great piece about the concept of credible neutrality. The only way for a blockchain system to achieve credible neutrality and long-term decentralization of power is to lock down the protocol rules. The thing that caused Ethereum to succeed was the yellow paper. Ethereum has outperformed every other smart contract platform because the EVM has clear semantics with many implementations, so people can invest time and resources into applications built on it. The EVM is apolitical, the EVM spec (fixed at any particular version) is truly decentralized. Team Ethereum can plausibly maintain credibility and neutrality as long as they make progress towards the "Serenity" vision they outlined years ago. Unfortunately they have already placed themselves in a precarious position by picking and choosing which catastrophes they intervene on at the protocol level.
But those are social and political issues. The major technical issue facing the EVM is that it is inherently sequential. It does not have the key property that transactions that occur "later" in the block can be validated before the transactions they depend on are validated. Sharding will hit a wall faster than you can say "O(n/64) is O(n)". Ethereum will get a lot of mileage out of L2, but the fundamental overhead of synchronization in L1 will never go away. The best case scaling scenario for ETH is an L2 system with sublinear validation properties like UTXO. If the economic activity on that L2 system grows larger than that of the L1 chain, the system loses key security properties. Ethereum is sequential by default with parallelism enabled by L2, while Bitcoin is parallel by default with synchronization forced into L2.
Finally, what about CSW? I expect soon we will see a lot of people shouting, "it doesn't matter who Satoshi is!", and they're right. The blockchain doesn't care if CSW is Satoshi or not. It really seems like many people's mental model is "Bitcoin (BSV) scales and has smart contracts if CSW==Satoshi". Sorry, but UTXO scales either way. The checksig trick works either way.
Coin Woke.

https://pandawanfr.github.io/GarlicRecipes/
You can also find community guides in our discord linked above.
3. What is Garlicoin?
Garlicoin is a cryptographic, transactional, and secure virtual currency, similar to Bitcoin and Litecoin. By nature, this was started as not only a meme-currency, but also a community-driven currency as well.
Birth of Garlicoin
Although it looks like a joke at first glance, it’s a real currency that was built with a community focus. We wanted to give the community a chance to be a part of a cryptocurrency’s development from A to Z. No other cryptocurrency has ever accomplished this pre-launch on a scale that we have. We’ve had the opportunity to pool suggestions from over 100,000 users allowing us to hear concerns, suggestions, and develop around these.
Garlicoin was built on the basis of three selling points, in order of importance:
  • A fun, light-hearted way to introduce and educate a new demographic to these uncharted waters that we call “Cryptocurrency”
  • ASIC resistance
  • Scalability
4. Garlicoin Technical Details
At launch, Garlicoin will include:
Max coin supply: 69 million (decided by community vote)
Block time: Every 40 seconds
Starting block reward: 50 GRLC
Proof of work: Scrypt-adaptive-N (ASIC resistant)
Difficulty Adjustment: Dark Gravity Wave (alters difficulty every block for more regular block times)

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
