In short
- Bitcoin first launched on January 3, 2009, with the creation of the genesis block.
- Though its pseudonymous creator Satoshi Nakamoto could have mined 1.1 million BTC, he’s solely identified to have ‘spent’ 10 BTC.
- The block incorporates quite a lot of easter eggs, considered one of which strongly hints on the goal of the Bitcoin blockchain.
On Saturday, January 3, 2009, Bitcoin was born. With the creation of the very first Bitcoin block—referred to as the ‘Genesis Block’—the primary set of fifty BTC was mined into existence.
This genesis block is taken into account the beginning of the Bitcoin blockchain—and the start of the cryptocurrency revolution.
Many would argue that the day it was minted represents Bitcoin’s birthday. Although others as an alternative consider that Bitcoin’s birthday is definitely three months earlier—when the Bitcoin whitepaper was first launched.
As the primary block ever created, the genesis block is the beginning of the immutable database that’s the Bitcoin blockchain, and represents the primary instance of a peer-to-peer digital forex secured by sound cryptographic ideas. However not like different blocks, it has a number of distinctive properties, including a layer of hidden that means that may not be obvious at first look.
What’s a Genesis Block?
A genesis block is just the primary block mined on a blockchain community.
Blocks are usually added to blockchains both by miners (on proof-of-work networks equivalent to Bitcoin) or validators (on proof-of-stake networks equivalent to Ethereum). Every new block data transactions and references the earlier block within the chain.
Nonetheless, as a result of the genesis block initiates the blockchain and doesn’t have any earlier blocks to refer again to, it’s created by the blockchain’s builders. Within the case of Bitcoin, that’s its pseudonymous creator, Satoshi Nakamoto.
The genesis block establishes the principles beneath which the blockchain operates, equivalent to mining problem and block rewards. Bitcoin’s genesis block set the reward for mining a block at 50 BTC, which halves roughly each 4 years till its provide cap of 21 million BTC is reached.
The Genesis of Bitcoin
The Bitcoin genesis block was initially known as ‘block 1’, however is now usually described as ‘block 0’ by trendy shoppers—this quantity refers to its block peak, i.e. its distance from the very first block within the blockchain.
Each successive block is linked collectively, therefore the time period ‘blockchain.’ That is key to blockchain’s immutability and safety.
Every block incorporates details about the transactions in that block and a hash from the earlier block it’s linked to, with the following block containing the hash of all the information from the earlier block, and so forth. It signifies that if one transaction is altered, the entire chain is corrupted.
Like all blocks, Bitcoin’s genesis block had a block reward related to it. Because the first-ever block mined, this reward was precisely 50 BTC, however following a succession of block reward halvings, as of April 2024 newly-mined blocks now yield simply 3.125 BTC as a reward.
Sometimes, this subsidy could be distributed to the miner liable for efficiently mining the related block, who might then spend it as they please. However the genesis block is the exception to this rule. Although the reward was transferred to a daily deal with: ‘1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa’—it can’t be spent. This is because of a presumably intentional quirk or bug, which prevented the transaction from being added to Bitcoin’s UTXO database.
“The genesis block, as the primary block in existence, can’t be linked to a earlier block, which provides it some bizarre properties. This doubtless led to Satoshi’s choice to not submit the 50 BTC reward to Bitcoin’s transaction database,” AllianceBlock Founder and CTO Matthijs de Vries informed Decrypt.
Nonetheless, every other BTC despatched to the primary Bitcoin deal with will be spent as regular by the deal with’ proprietor (who’s, presumably, Satoshi). In whole, a further 99.80 BTC (price round $6.1 million) has been despatched to the deal with as of April 2024.
The deal with tends to obtain a number of funds every week and no person is aware of precisely why—some theorize that it is a manner of claiming “thanks” to Satoshi or that others have merely set it as their change deal with. Notably, in January 2024, one consumer despatched 26.92 BTC, then price over $1.2 million, to the “genesis pockets” deal with.
It is potential that at the very least a few of these transfers intend to pressure Satoshi to inadvertently reveal his (or her) identification by way of the ‘common-input-ownership heuristic‘, which might probably be used to hyperlink a transaction to a real-world identification beneath the precise circumstances.
Not like the overwhelming majority of Bitcoin blocks mined at present, the genesis block was nearly definitely mined by a pc utilizing its central processing unit (CPU). The primary block solely had a problem of 1, which suggests it was doubtless mined virtually immediately. As of April 2024, the block mining problem stands at 88.1 trillion (and rising)—requiring extremely specialised mining {hardware} referred to as an ASIC to stay aggressive.
Curiously, there was a 6-day delay between the creation of the primary block and the second block—somewhat than the 10-minute delay that we see at present. This has led some to invest that Satoshi was emulating the story of creation from the Ebook of Genesis—by which the Judeo-Christian God creates the Earth and every thing round it in 7 days, with the seventh day being a day of relaxation.
The early days of Bitcoin
On 31 October, 2008, Bitcoin was introduced through a preferred cryptography mailing list. That is when Satoshi Nakamoto printed the Bitcoin whitepaper, titled Bitcoin: A Peer-to-Peer Electronic Cash System.
It wasn’t till three months later that the Bitcoin community really grew to become operational—when Satoshi mined the aforementioned genesis block.
The earliest model of Bitcoin’s supply code, dated November 17, 2008, was uploaded on Bitcointalk by consumer ‘Cryddit’ in 2013 and incorporates a number of attention-grabbing options that trace at Satoshi’s thought course of when creating it.
For instance, Satoshi refers back to the smallest unit of a Bitcoin (now referred to as a satoshi) as a cent—indicating he could have believed that 100 millionths of a Bitcoin could be the equal of 1 cent—placing the worth of Bitcoin at $1 million apiece.
He additionally described the Bitcoin blockchain as a ‘timechain’, since it’s primarily a chronological document of all of the occasions that occurred on the Bitcoin community.

Though the Bitcoin community first went reside on January 3, 2009, it took greater than per week earlier than the primary Bitcoin transaction was really made. In accordance with January 12, 2008 tweet, it seems that early cypherpunk Hal Finney was the primary individual to obtain Bitcoin on the community.
This transaction passed off in block 170 and was a direct switch of 10 BTC from Satoshi Nakamoto to Hal Finney. Past this, it’s thought Satoshi Nakamoto hasn’t spent any of this estimated 1.1 million BTC hoard.
The worth of BTC was largely arbitrary for the primary 12 months and a half of its existence, however one of many first documented business purchases utilizing the cryptocurrency occurred in Could 2010, when pc programmer Laszlo Hanyecz paid 10,000 BTC for 2 pizzas price $41. On the time, this pegged the worth of every BTC at roughly $0.04—a far cry away from its present worth of $61,000. As of April 2024, the Bitcoin that paid for these pizzas could be price round $612 million.
The Easter Egg
When the Bitcoin whitepaper was first launched in November 2008 the world was within the midst of a worldwide recession
This era, now referred to as the ‘Nice Recession’, noticed a dramatic decline in nationwide economies between 2007 and 2009, with many international locations seeing their unemployment charges skyrocket, inventory markets crash, and housing markets plummet.
Furthermore, numerous each personal and business banks collapsed, main governments and banks around the globe to start implementing fiscal insurance policies designed to stimulate struggling economies—together with quantitative easing and slashing rates of interest.
As a reference to this example, Satoshi included a hidden message referencing British newspaper The Times on the genesis block’s coinbase timestamp parameter:
Satoshi additionally hid the identical textual content in reverse on line 1616 of Bitcoin’s authentic code. This was hidden because the hexadecimal string, which when transformed into textual content utilizing a HEX to TEXT converter reveals the textual content:
Due to the timing of its launch, along with the hidden message contained within the genesis block, it’s broadly believed that Bitcoin was launched to offer an alternate financial system designed to withstand the challenges confronted by many conventional currencies—like inflation, counterfeiting, and corruption.
