Before launching Bitcoin on 8 Jan 2009 Satoshi had an early version coded. This is known as the November 2008 Version. Here are the 10 changes he made to what became Bitcoin as we know it today. 🧵Thread👇

I am running the EXACT same client Hal was running when he made this tweet? (on my Mac M1 Max) Why is it Bitcoin v.0.1.1? How do I know? How did I do it? 🧵Thread👇

Happy Gavin went to the CIA to talk about Bitcoin day. (for those who celebrate)

Yes, this is what I'm doing in 2025.

I want to sell a .pdf via LN. Is there a service I can use to set this up? I will share a link to someone and if they pay 1$ they get a .pdf I know I could do this with BTCPay or LNBits if I host it, but don't want to host anything, and more importantly I do not want to set up a node, manage liquidity.

Did you know Satoshi worked for 1 year and a half on Bitcoin's code before releasing the White Paper? He mentions this in a conversation on the Cyphterpunk Mailing list on 17 Nov 2008. 2weeks after the lunch of the White Paper.

Did you know Satoshi initially implemented a review system in #Bitcoin. This was meant to work with the market-place. Code for both of these was still present in the 1st versions of Bitcoin, but not used.

Did you know that on 30 March 2010 bitcointalk user SmokeTooMuch wanted to auction 10,000 BTC for $50. No one took the offer. 24 Feb 2012 (2 years later) he shares no one took the offer, but it would be quite a lot of money. They were worth $50,000 | 1000x increase.

Did you know? The 1st Bitcoin price was $1 = 1,309 BTC on New Liberty Standard exchange. 5 October 2009 The price was calculated by dividing $1.00 by the average amount of electricity required to run a computer with high CPU for a year. And the 1st EVER transaction on this platform was done by legendary super OG bitcoin dev @Sirius aka Sirius.

Found the first known bitcoin to USD transaction from my email backups. I sold 5,050 BTC for $5,02 on 2009-10-12. https://t.co/8XcBmzJljf

Did you know? The original Bitcoin Client v0.1 release by Satoshi had an unfinished Poker game & an eBay-style marketplace in the source code. Satoshi also had plans to implement an escrow system but this never came to fruition.

Absolute must watch

How did Satoshi chose the 21M limit for #Bitcoin? He reveals in an email with @Sirius that it was an educated guess. He wanted to pick a number and issuing schedule that would work if Bitcoin would become mainstream but also if it stayed niche.

Did you know the original Bitcoin client had a Generate Coins button? When activated it would use the CPU to mine Bitcoins. It was removed with Bitcoin 0.3.22 in June 2011 as mining become more specialised and moved away from solo-miners.

Did you know that on 15 August 2010 two TXs that contained 184 BILLION bitcoins were created at block 74,638? This exploited the lack of checks on the values of TX outputs. A fix that enforced the check was deployed 5 hours after the discovery. The problematic TXs was removed.

Over the last 2 years 96% to 99% of the blocks were mined by only six mining pools.

Did you know that the Bitcoin white paper was created on Windows XP with Open Office Writer 2.4? We know this from the .pdf meta data + WizSec Bitcoin Research recreated the white paper perfectly only in these conditions. At lunch Bitcoin 0.1 was only for Windows. Linux came on 0.2
