The genesis block
The genesis block, which is the first block in a blockchain, in Bitcoin was created by Satoshi Nakamoto. It is statically coded so that everyone who runs a Bitcoin core node will only believe one blockchain state.
The genesis block hash can be fetched by fetching the block hash of the 0th index:
$ bitcoin-cli getblockhash 0 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f
The following are the block details of the Bitcoin genesis block. This block has a coinbase transaction and no other transactions:
$ bitcoin-cli getblock 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f { "hash": "000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f", "confirmations": 521239, "strippedsize": ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
