The Genesis Block
The genesis block (AKA block0) is Satoshi Nakamoto’s hard coded block that launched the Bitcoin network on 3 January, 2009 (at approx 18:15:05 UTC). (R1)
For Bitcoin (and most of its’ altcoin children), block0 is hard coded and generates un-spendable rewards because it is the first block in a new chain (hence the phrase “blockchain”). Bitcoin’s block0 contains a message in its’ coinbase parameter (a field used to send block rewards to miners). It is a reminder of why Bitcoin was invented to begin with.
It reads: “The Times 03/Jan/2009 Chancellor on brink of second bailout for banks”. Meaning Bitcoin was invented to make future financial institutions accountable for their actions.
At the time, banks all over the world were getting bailed out by their governments, because the banking system had allowed massive debts in the real estate market that nearly caused the whole global economy to collapse. You can learn a lot more about the 2008 financial crisis here and here.

(R1) Genesis Block hex message converted to ASCII on the right hand side
3 January 2009 was the start of Web3 because at the core of its beginnings is decentralized accountability and self-sovereignty over existing Web2 control, censorship, and most of all – centralization. Bitcoin brought accountability to a financial system that long abandoned that idea in favor of mountains of debts and it “sparked the idea that peer-to-peer and censorship-resistant money can exist, removed from governments, corporations, and any single entity.” (R1)
Web3 is essentially the opposite of how the Web2 Internet works today, because the blockchain makes all transactions using it accountable and secure. Accountable because blockchains record and keep all transactions that ever used it; and secure because all blocks in a chain build upon each other.
Also, users own their own data (ie. they have “self-sovereignty”), meaning users can be their own bank and not need third parties to help settle transactions for them. They are free to spend their money wherever they want, whenever they want.
Future Web3 technologies may even go beyond blockchain to achieve the same level of accountability and consensus at much higher speeds than we have today with Visa and Mastercard.
After block0 the timestamp for block1 came 6 days later: “One interpretation is that Satoshi was working on bitcoin for some time beforehand and the The Times front page prompted him to release it to the public. He then mined the genesis block with a timestamp in the past to match the headline. It is also possible that, since the block’s hash is so low, he may have spent 6 days mining it with the same timestamp before proceeding to block 1” (R2)
