Bitcoin's 777,777th Block.

The 777,777th block of the Bitcoin blockchain was mined on January 14th, 2021. This block contained 1,187 transactions and had a block size of 1.25 MB. It also marked a significant milestone for the Bitcoin network as it represented the successful completion of the 3rd Bitcoin halving event, which occurred on May 11th, 2020.

Bitcoin halving is an event that occurs approximately every four years when the reward given to Bitcoin miners for solving a block is reduced by half. This event is built into the Bitcoin protocol and is designed to limit the supply of Bitcoin to a maximum of 21 million coins, ensuring that the digital currency retains its value.

The 777,777th block also contained a special message in its coinbase transaction, which is the transaction that generates new Bitcoin and rewards it to the miner who successfully solved the block. This message read "NYTimes 10/Mar/21 House Gives Final Approval to Biden’s $1.9T Pandemic Relief Bill."

This message was a reference to the famous message included in the first block of the Bitcoin blockchain, which read "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks." The inclusion of this message in the 777,777th block was a nod to the fact that Bitcoin has come a long way since its inception and has become a significant player in the global financial system.

Overall, the 777,777th block was a significant milestone for the Bitcoin network, marking the completion of a major event and highlighting the continued growth and adoption of the world's most popular cryptocurrency.
