Knowledge Notes | The History of Bitcoin
① In early 2023, the Ordinals protocol emerged, allowing people to inscribe data such as images into Bitcoin transactions. BRC-20 tokens followed.
② On January 3, 2009, the Bitcoin genesis block was created. Embedded in the block was a front-page headline from that day’s *The Times*.
③ When checking dates and block heights in Bitcoin’s history, rely on records from block explorers rather than secondhand accounts.
