In brief<\/h4>\n\n- The block contains a number of easter eggs, one of which strongly hints at the purpose of the Bitcoin blockchain.<\/li>\n<\/ul>\n<\/div>\n
On Saturday, January 3, 2009, Bitcoin<\/a><\/span> was born. With the creation of the very first Bitcoin block\u2014known as the ‘Genesis Block’\u2014the first set of 50 BTC was mined into existence.<\/p>\nThis genesis block is considered the start of the Bitcoin blockchain<\/span><\/a>\u2014and the beginning of the cryptocurrency<\/span><\/a> revolution.<\/p>\nMany would argue that the day it was minted represents Bitcoin’s birthday. Though others instead believe that Bitcoin’s birthday is actually three months earlier\u2014when the Bitcoin whitepaper<\/a> was first released.<\/p>\nWhat is a Genesis Block?<\/h2>\n
However, because the genesis block initiates the blockchain and doesn\u2019t have any previous blocks to refer back to, it is created by the blockchain\u2019s developers. In the case of Bitcoin, that\u2019s its pseudonymous creator, Satoshi Nakamoto<\/a>.<\/p>\nThe genesis block establishes the rules under which the blockchain operates, such as mining difficulty and block rewards. Bitcoin\u2019s genesis block set the reward for mining a block at 50 BTC, which halves<\/a> approximately every four years until its supply cap of 21 million BTC is reached.<\/p>\nThe Genesis of Bitcoin<\/h2>\n
Like all blocks, Bitcoin\u2019s genesis block had a block reward associated with it. As the first-ever block mined, this reward was exactly 50 BTC, but following a succession of block reward halvings, as of April 2024<\/a> newly-mined blocks now yield just 3.125 BTC as a reward.<\/p>\nTypically, this subsidy would be distributed to the miner responsible for successfully mining the associated block, who could then spend it as they please. But the genesis block is the exception to this rule. Though the reward was transferred to a regular address: ‘1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa’<\/a>\u2014it cannot be spent. This is due to a possibly intentional quirk or bug, which prevented the transaction from being added to Bitcoin’s UTXO database.<\/p>\nThe 50 BTC block reward associated with block 0 is unspendable.

This likely led to Satoshi\u2019s decision to not submit the 50 BTC reward to Bitcoin\u2019s transaction database,” AllianceBlock<\/span><\/a> Founder and CTO Matthijs de Vries told Decrypt<\/i><\/span>.<\/p>\nNonetheless, any other BTC sent to the first Bitcoin address<\/a><\/span> can be spent as usual by the address’ owner (who is, presumably, Satoshi). In total, an additional 99.80 BTC (worth around $6.1 million) has been sent to the address as of April 2024.<\/p>\nThe address tends to receive several payments each week and nobody knows exactly why\u2014some theorize that it’s a way of saying “thank you” to Satoshi or that others have simply set it as their change address. Notably, in January 2024, one user sent 26.92 BTC, then worth over $1.2 million<\/a>, to the \u201cgenesis wallet\u201d address.<\/p>\nIt’s possible that at least some of these transfers intend to force Satoshi to inadvertently reveal his (or her) identity through the ‘common-input-ownership heuristic<\/a>‘, which could potentially be used to link a transaction to a real-world identity under the right conditions.<\/p>\nUnlike the vast majority of Bitcoin blocks mined today, the genesis block was almost certainly mined<\/a> by a computer using its central processing unit (CPU). The first block only had a difficulty of 1, which means it was likely mined practically instantly.
