Bitcoin Unix Epoch "Y2K bug"?

I'm new to bitcoin, and have been reading the excellent Mastering Bitcoin O'Reilly book by A Antonopoulos and like, I have a really obvious question. Blockchain headers contain a 4-byte Unix timestamp (seconds since Jan 1, 1970). Unix timestamps will overflow on January 19, 2038 03:14:07 GMT, but the bitcoin network is supposed to be more or less operational (ie handing out more bitcoin to lucky miners) until 2140.
Ok so my question: what's going to happen to bitcoins mined before the epoch expiration? since this is in the block header, will it fuck up the chain? why didn't anyone think of this when they were putting the protocol together? or are people actively fixing this? is bitcoin as we know it fucked?
discuss.

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.

I've been sharing conspiracies on reddit longer than this sub has been around. I have a story to tell.

This story is mostly crafted from my own experiences, my conversations with some of the people involved, and the rest is my own guesswork as I try to fill in the gaps...so bear with me!
That's why I wanted to share with this community, which I've watched grow over the years. I remember posting about the death of Barry Jennings (who witnessed explosions in the WTC on 9/11) the day after it happened. This was before /conspiracy (or right around when it was formed), and I remember thinking "we really need a sub for conspiracies on reddit!"
And here we are, 12 years later and over 1.3 million subscribers...incredible!
So...
My story starts with a young man. We'll call him Andrew.
Andrew grew up in the 90's in a coastal US town and quickly blossomed into a tech whiz at a young age.
He began building his own computers, and after a brief stint using Windows, he decided that Bill Gates was everything wrong with technology (and the world), and he made it his mission to make sure folks like Gates were NOT the future of computers.
He really believed that the use of technology was a fundamental human right, and that charging people for "proprietary" OS's that hid their source code was a violation of these rights.
He saw a possible Deus Ex-like future, with a technocracy literally around the corner if we didn't act now.
Andrew soon joined the Free Software Foundation and began rubbing elbows with the likes of Richard Stallman. He begun exclusively using GNU/Linux and was the type to correct you if you called it just "Linux". He also began visiting tech-savvy forums like slashdot and started networking in earnest.
By 2006 (his senior year of high school) Andrew was completely over his "education" and decided to just drop out completely.
Shockingly, a college accepted him anyway. A small East Coast school had been actively courting Andrew, and when they learned he had failed to get his HS diploma, they accepted him anyway!
Now sometime during this period Andrew went to Iceland and stayed in Reykjavik for several months.
This trip may have happened during the summer, fall, or early winter of 2006. The reason for his trip had something to do with his efforts in the FSF or similar group. The possible significance of this trip will become clear as we go on.
What is clear is that Andrew started college in the fall of 2006, and that the circumstances were unusual. Andrew soon met several like-minded individuals and began building a social and technological network at his school.
Two individuals in particular would become key players in his life (one more prominently in this story, but the other was significant as well), and eventually the 3 would live together in town for several years.
But for now let's stick with Andrew.
Andrew had an idea to build a social network for his college. Except, it wasn't just a network, it was a wiki for information about the school...and beyond. Soon, it began to morph into something much bigger in Andrew's mind.
He saw his project as being one of many data "hubs" for leaks of important documents and otherwise sensitive information.
So yeah, he saw the opportunity for a wiki for leaks (see where this is going yet...?).
As his ambitions grew, his behavior started to become increasingly erratic. He was caught with drugs and arrested. Strangely, the charges were pretty much dropped and he was given a slap on the wrist. Eventually he decided to leave the school, but still lived in town and had access to the servers on campus.
By 2010 Andrew was still living in the small town with his two "hacker" buddies, who were still enrolled at the school.
This house was in some ways legendary. It appears that many "interesting" people spent time at or visited the residence. Indeed, some of the early movers and shakers of /conspiracy itself passed through.
There was usually a full NO2 tank for anyone who was into that kinda thing, and they were stocked with every hallucinogen and research chemical known to man.
It was also likely under surveillance by multiple intelligence agencies (NSA/Mossad/etc).
Over time, the mental state of Andrew was slowly starting to deteriorate, which wasn't helped by his abuse of drugs.
Still, Andrew decided to move his base of operations to Europe, spending time in Belgium, the Czech Republic and elsewhere.
One of his housemates was soon to join him on his adventures in Europe and elsewhere abroad. We'll call him "Aaron."
Aaron had a very similar story and upbringing as Andrew. Aaron was also from a coastal US town and was born into privilege. He was also, supposedly, born into a family with some serious connections to intelligence agencies, including an uncle with ties to the NSA, and both parents connected to military brass.
By 2015, Andrew and Aaron were living together in the Czech Republic. During this time they were working directly and/or indirectly for the NSA (via Cisco and other companies).
You see, the "college" they met at was actually a front for the recruitment of kids into the IC. Apparently, many "schools" in the US function that way. Go figure.
Their intelligence and valuable skill set (hacking etc) made them valuable assets. They were also possibly involved with the distribution of certain "research chemicals" (of the 2C* variety) to dignitaries and their entourages (in one example, they provided 2CB to a group with David Cameron).
In addition, Andrew was allegedly involved with, or stumbled upon, an NSA-linked surveillance project directed at the entire country of Malaysia, while Aaron was involved with Cisco.
Aaron himself had gotten into hot water for releasing damaging information about the NSA, and even claimed to be an NSA whistleblower, and was also possibly the individual who leaked the 2014 (or 2015) Bilderberg meeting list.
And then things went bad. Andrew quit the Malaysia project and Aaron left Cisco. It seems Andrew and Aaron were "set up" during a fiery false flag event in the Czech Republic in 2015. It may have happened at an embassy, but it's unclear which. There is no information on the web about anything like this (afaik).
Aaron was immediately targeted and spent several years on the run. Allegedly, he was added to the list of victims in the so-called "Great Game".
The Great Game is the term used for an international assassination program where intelligence agencies share a list of targets to be neutralized. The German BND and Mossad are heavily involved, as other networks. Individuals targeted by the Great Game may be offed by actual assassins, or by NPC-like humans whose minds will be influenced by mind control tech (a la Matrix...say influencing someone to ram your car unwittingly ie).
As Aaron went on the lam, Andrew soon returned to the US, shell-shocked by his experience.
Both Andrew and Aaron continue to suffer from some sort of PTSD from these series of events, rendering Andrew largely incapacitated and Aaron scattered and discombobulated.
The Meat of the Matter
OK...where does that leave us? Why am I sharing all of this? I think there's much more to this story.
So let's start speculating! Everything I'm about to say is stuff that was told to me personally. I can't vouch for any of this information, though obviously I thought it was compelling enough to share.
Here's the gist: The so-called whistleblowers you see in the media are almost all fake.
This includes: Edward Snowden, Julian Assange, Thomas Drake and William Binney (hey look, his AMA is pinned on this sub right now...no comment!). These individuals, and others, are controlled opposition. The real whistleblowers are severely punished.
For example, Bradley Manning was punished with chemical castration in jail. His "transformation" was chemically induced torture.
Andrew was not alone in his passion. There were lots of other young visionaries like him who dreamed of a freer and more transparent world.
In this story, Julian Assange was an intelligence asset...a psyop meant to steal the thunder from real activists like Andrew.
In this story, a small college-based "wiki" for government leaks was used as the model for an intelligence operation known as "wikileaks".
In this story, Andrew traveled to Iceland at some point in 2006.
When was Wikileaks founded? Wikileaks was founded by Julian Assange in December 2006, in Iceland.
Aaron discovered (legally, like Manning who had clearance to access all the data he leaked) damning information about surveillance happening by the NSA, specifically against recruits entering the US army and elsewhere.
In this story, the "Andrew" identity was co-opted and turned into "Julian Assange", and "Aaron" became "Edward Snowden".
Granted, there were probably other people that these whistleblower imposters were modeled after, but Andrew and Aaron seem like very strong contenders for some of this inspiration.
Now, much of the following may be gobbledygook (lol I spelled that right first try!) for all I know, but since I'm having a really hard time making sense of it all, I'll just include everything I can and let you guys run with it.
Here are some phrases, ideas, terms and people of note that may be involved with this story...MODS: None of this is doxing! All of the links of people are wikipedia pages or published interviews/articles. So yeah. Not dox!
IN CONCLUSION
I don't know how these terms, theories and individuals fit into this story, but that they may be somehow related.
Hopefully there are enough bread crumbs in here to keep some of you busy!
Any help/insight would be appreciated. I confess I'm not so tech-minded so I can't offer any more explanation about some of the more techy terms.
Anyway, thanks for reading, and thanks for continuing to stimulate after all these years! It's really nice to see this place continuing to thrive after all of this time!

Integration broker for P2P apps on BCH Chain
Alright guys, I apologize for all the shilling on this sub for this project, but it was suggested by the admin.
This flipstarter has 1 day left before it expires, and needs one last push to get it through.
CashSQL: the integration broker helps you get data out of (and put data into) the BCH chain through a nice and easy SQL database of your choosing. It's designed to help build P2P apps rapidly. Enveloping data transactions inside layer-1 BCH is tough. If apps could rely on a simple SQL DB, with community developed data-transformers, life is easier for all apps using those layer-2 protocols. This means more devs, more apps and more activity on BCH.
If this project makes sense to you, consider a PLEDGE NOW!

CashSQL Vision

DELIVERABLE SUMMARY

  • Full Blockchain Database: the entire BCH blockchain available as SQL database. Useful for chainalysis, data analytics, etc. This database can be optionally deployed by users.
  • Light-weight Database: lean and mean database for tracking user-specific blockchain data. Most applications will only need to use this.
  • DBMS support: SQL Server, MySQL/MariaDB and SQLite (has plug-n-play design, others can be added later).
  • Mempool Integration: JSON/XML/Web-Socket API for real-time event data.
  • Simplified Schema Design: blockchain data is extracted and processed into higher-level data abstractions that developers can easily use. For example, account balances, debits and credits for BCH and SLP addresses, confirmations for transactions, etc.
  • Extensible Schema: users can extend scheme with custom columns and tables that suit their applications.
  • Transformable Data: users can plug-n-play custom data-transformations that extract meaningful high-level data from compressed blockchain data.
  • Real-Time Capability: databases are maintained in real-time with minimal locking.
  • Send Capability: includes “outbound” tables for users to push out transactions onto the network. Includes send receipts and history tables.
  • High-performance: expertly-tuned database design for large and small deployments.
  • Enterprise-ready: Written in latest C#/.NET, a popular enterprise-class platform.
  • Cross-Platform: Target platform is .NET 5 which runs on Windows, Linux, macOS and Unix.
  • Simple GUI: an explorer-like GUI is shipped with the backend based on HTML5.
  • Open Source: Fully open-sourced under MIT license.
A prototype is currently available at http://blockchainsql.io.

WHO WE ARE

Sphere 10 Software (ABN: 39600596316) is an Australian based LLC led by Director and Chief Software Architect, Herman Schoenfeld. Herman has been involved in cryptocurrency since 2011, and was the "retrospective co-founder" of the PascalCoin cryptocurrency. Herman has appeared in commercial programming aired on Bloomberg and Fox Business News as well as radio broadcasts in the NYC area. Herman has been a long-time supporter of Bitcoin Cash and has always promoted it as the true, original Bitcoin as laid out in the Satoshi whitepaper. However, due to certain personalities dominant in BCH, Herman was de-motivated from participating until now. Since the BSV split and with the prospect of BCHN taking node leadership in November, Herman is very bullish on BCH and motivated to support BCH into the bright future and imminent explosive growth it was destined for. Sphere 10 Software will allocate 2 developers to work on CashSQL (one of them Herman). All the funds from this fund-raiser will be used for paying the time and material of development.

Hi, All!
I made the Makefile (for local-user home directory only! You need root access only for adding a 'bitcoin' user!) for compiling the bitcoin UASF-enforced node from sources for any Unix with old prerequired-software for Bitcoin node - for example for CentOS 6.. For example this OS has old (for bitcoin sources): pkg-config, autotools, gcc (main reason!), openssl and etc. Now you can add the bitcoin user in Unix, put there Makefile and do from 'bitcoin' user in shell: "make bitcoin-uasf_install" and everything will be done! Don't need root access for installing and starting! And everything will be compiled and installed from sources (autotools, pkg-config, m4, openssl, gcc 7. and of course bitcoin UASF) under local home directory. After you can 'tar' this home directory, to move to other host with same OS and untar there! All will work! I tested it many times!
Welcome!

Is there a curl or nc command to test node reachability?

I'm looking for a simple curl or nc command to tell me if a node is reachable. The only thing I can come up with when I read through the docs would be to send the "version" message described below, but it only partially succeeds.
Are there any simpler bits I can fling at the port to know if its up?
My failed attempt to send a version message to my node. I just hand crafted this message so the fact that the IP and port are wrong may be fatal. I'm not sure if the bitcoin protocol responds on the same connection or opens a separate port for the verack message.

Now it's time to promote BCH as the real bitcoin

BTC and ETH fees are consistently high and BCH now has a unique opportunity to gain wider recognition.
We have to market BCH as a coin that's designed better than BTC and ETH because it can accomodate 10x more users.
BTC was designed poorly even as a store of value/hodl coin because only rich people can accumulate, shuffle and transfer coins without losing hundreds of dollars on fees.
ETH was designed poorly because you never know how much gas you should pay and the gas price bidding process is similar to BTC's.
BCH is best for payments - we all know that but it is more important that we promote it as a store of value because that will attract mainstream adoption and institutional investors.
People can use BCH to accumulate wealth over time, buying when they have only a few dollars to spare. They can also shuffle coins and stay anonymous without paying hundreds of dollars on fees.
We need a strong stablecoin like tether (centralized) and DAI (decentralized) because it's easier to pay with a stablecoin and calculate taxes where applicable.
It would be great if USDH or a similar stablecoin gets some investors/funding + media coverage and possibly audits...

I was following 402 Payment Required's LN video over here (https://www.youtube.com/watch?v=q0siLF9zmWo) and everything was good so far, until the moment of the first Initialization of my LN node, I got an (dial tcp my-external-ip:9735: connect: connection timed out) error.
I was starting the Initialization by the following way

Problem with the first Initialization of my LN node, dial tcp my-external-ip:9735: connect: connection timed out

Background
I was following 402 Payment Required's LN video over here (https://www.youtube.com/watch?v=q0siLF9zmWo) and everything was good so far, until the moment of the first Initialization of my LN node, I got an (dial tcp my-external-ip:9735: connect: connection timed out) error. Your environment
I was starting the Initialization by the following way
lnd --externalip=X.X.X.X
And I've my lnd configuration file with the following attributes
alias= debuglevel=debug bitcoin.active=1 bitcoin.mainnet=1 bitcoin.node=bitcoind
I created the file (before) I started the Initialization.
version of lnd: I don't know, I guess it's the latest version. which operating system (uname -a on *Nix): Ubuntu 18.04 version of btcd, bitcoind, or other backend: bitcoind 0.19.1 any other relevant environment details: My Ubuntu is running on a VM machine with a (bridged) internet connection

Make your own stakebox. Ultimate beginners guide how to compile any wallet on AARCH64 (Raspbery pi and other SBC)

I contemplated to wrote this for a long time, so it's finally time.
As you know a lot of altcoins uses PoS (Proof-of-stake) way of "mining" coins. Which basically means, that you hold coins on your unlocked wallet and you are receiving stakes as a reward. This requires very little power and it can bring you a lot of rewards, at just 10W from the wall.
So first I am using latest Raspbian on RPI4B 4GB in this example.Setting up Raspbian is not part of this process since it's very well documented. I recommend to change user from pi to something else due to security concerns and you can also do other stuff just search "security Raspberry PI" and you find a lot of articles, but this is not the focus of this guide.
I know there are a lot of guides on the internet, but I am using like 5 sources, so it's compiled what other people wrote and some of my research.
I am using AnyDesk insted of SSH or VNC server, because it works it's ligthweit and it just works.
So after you see the gui of Raspbian, just launch terminal (CTRL + ALT + T) and do basic thing:
sudo apt-get update && sudo apt-get upgrade
Than press Y and let it run, after is finished, we need to prepare so dependency packages. Since most of the wallets using Berkeley DB 4.8 we need to obtain it.
So in terminal wrote:
cd cd Downloads wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install 
So wait unti it's finished and than you can delete files in Downloads folder in gui or use:
sudo rm -r [folder] 
So next thing we need to install some libraries.
sudo apt-get install git build-essential libtool autotools-dev autoconf pkg-config libssl-dev libcrypto++-dev libevent-dev libminiupnpc-dev libgmp-dev libboost-all-dev devscripts libdb++-dev libsodium-dev 
And pres y and let it run. After that another set of libraries:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libcrypto++- dev libminiupnpc-dev qt5-default 
And then again pres y and let it run. Some wallets need older version of libssl1.0-dev, so for for safe compiling we install that as well:
sudo apt-get install libssl1.0-dev 
Pres y and let it run. Warning don't use sudo-apt get autoremove, since it would wipe this package, since it's old.
Next thing we are going to obtain Bitcoin PPA filest, which can be done like this.
cd /etc/apt/sources.list.d/ sudo nano bitcoin.list 
Paste this in there:
deb-src http://ppa.launchpad.net/bitcoin/bitcoin/ubuntu artful main 
And CTRL+X and than y, then do this:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv C70EF1F0305A1ADB9986DBD8D46F45428842CE5E sudo apt-get update 
So now we are ready for compiling. So we are going create folders. CD yourself where this folder should be situated, if you for example have plugged in some external drive. Then:
mkdir Crypto cd Crypto 
And then we have to choose wallet which you want to compile. I am choosing Streamies (STRMS) as an example, since it's pretty good coin for staking. So:
mkdir Streamies cd Streamies 
Then go to the github page and click on the green button on the left and click copy to clipboard, which gives you git link.
git clone https://github.com/Streamies/Streamies.git 
Watch the output folder which it creates, it's stated in the first two lines and copy then by highliting the text and CTRL+SHIFT+C copy it to your clipboard.
cd Streamies (this is that git created folder) ./autogen.sh ./configure CPPFLAGS="-I/uslocal/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/uslocal/BerkeleyDB.4.8/lib" sudo make (this could take hours) sudo make install 
And you are done, files is going to be in folder /uslocal/bin (DO NOT delete git created folder, because you are going to need it for faster compiling, when wallet get's and update.)
cd /uslocal/bin 
Now you can list files by:
ls 
And then you can copy/move them where ever you want by using:
sudo mv * [destination full path] 
Let it run and go back to folder where you move those files.
sudo chmod +x streamies-qt (since we want to run wallet) 
In most cases compiled files are going to in format of "shared library" so we need to create script to run it. Open up a text editor from gui or through nano. And paste this to that file:
#!/bin/bash ./streamies-qt 
And save it as a sh file, for example run.sh. Then we need to make it runnable so:
sudo chmod +x run.sh 
Now to run it, it's just:
./run.sh 
And here we are glorious GUI wallet appears and you are done, you can paste blockchain, wallet.dat from other sources, so this migration is pretty easy and you, if you have it on for exaple flash disk.
So this is basic how to compile QT wallets on AARCH64. I am running 7 wallets, 2 of those are Masternodes and RPI 4B 4GB would handle way more, I am at best on half of my RAM.
Some wallets need more package, but it's not much of and issue, since compiling stops and you just copy paste nape which is missing put it in the google and add "apt-get" after the name of package and you are going to see, what is the name of the packages so it can be retreived from package assinstant aka apt-get. So basically:
sudo apt-get install [package name] 
Then press y and again wrote:
sudo make 
This process is going to continue where it was left off, so nothing is going to run from beginning.
Updating wallets is basically exactly same, just repeat steps from "git clone" and after that proceed as it was written above.
So I hope this helps some of you, to use this at home and not on some VPS, if you are anxious as me, to host my wallets on remote server.
