As the first block ever created, the genesis block is the start of the immutable database that is the Bitcoin blockchain, and represents the first example of a peer-to-peer digital currency secured by sound cryptographic principles. But unlike other blocks, it has several unique properties, adding a layer of hidden meaning that might not be apparent at first glance. The Genesis of Bitcoin The Bitcoin genesis block was originally referred to as 'block 1', but is now generally described as 'block 0' by modern clients—this number refers to its block height, i.
Every successive block is linked together, hence the term 'blockchain', and according to AllianceBlock Founder and CTO Matthijs de Vries, this is integral to the security of the blockchain. The next block will contain the hash of all the data from the previous block, and so on: 'the merkle tree,'" Matthijs de Vries told Decrypt. As the first-ever block mined, this reward was exactly 50 BTC, but due to a succession of block reward halvings over the years, newly-mined blocks now yield just 6.
Typically, 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. This is due to a possibly intentional quirk or bug, which prevented the transaction from being added to Bitcoin's UTXO database.
The 50 BTC block reward associated with block 0 is unspendable. Image: blockchain. Nonetheless, any other BTC sent to the first Bitcoin address can be spent as usual by the address' owner who is, presumably, Satoshi. In total, an additional The address tends to receive several payments each week and nobody knows exactly why—some theorize that it's a way of saying "thank you" to Satoshi or that others have simply set it as their change address. However, it's also 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 ', which could potentially be used to link a transaction to a real-world identity under the right conditions.
Unlike the vast majority of Bitcoin blocks mined today, the genesis block was almost certainly mined 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. Comparatively, the block mining difficulty is now at Bitcoin difficulty over time. Image: btc. This has led some to speculate that Satoshi was emulating the story of creation from the Book of Genesis—in which the Judeo-Christian God creates the Earth and everything around it in 7 days, with the 7th day being a day of rest.
The early days of Bitcoin On 31 October, , Bitcoin was announced via a popular cryptography mailing list. It wasn't until three months later that the Bitcoin network actually became operational—when Satoshi mined the aforementioned genesis block. Blocks are labeled by their block height, which is the numerical value of their distance from the genesis block.
Blocks are also referenced by their timestamp, but because timestamps can be out of order block height is preferred. This was six days before the official release of the Bitcoin Version 0. After Satoshi mined the genesis block, the next block was mined on January 9th, Some bitconers theorize that the gap between block 0 and block 1 has a religious connotation. He was the only miner, and he had to keep hashing until others joined the network.
But it is unspendable. This is because when a node initializes its copy of the block chain, the genesis block is not included. Rather it is hardcoded to act as the base root to assist nodes to synchronize the block chain in a way that guarantees that all nodes start at the same beginning. More specifically, the genesis block is included in the block database but not in the transaction database.
As a result, any attempt to spend the genesis block subsidy would be rejected by the nodes because the initial transaction is not found on the public ledger. Block explorers however may show the first transaction for illustration. It is likely that Satoshi decided not to add this coinbase transaction to the global transaction database to promote transparency and fairness. By ensuring that the rewards in the genesis block cannot be spent, the block chain also remains immutable.
If this initial coin was to be spent, the genesis block and subsequent blocks could be pruned, which would make it impossible for nodes to sync correctly or verify historical records from thereon. However, there was no block header from a prior block. Hidden Message in the Genesis Block Contained in the genesis block is a hidden message in its coinbase parameter hexadecimal. The British government had failed to stimulate the economy, and things were falling apart.
Also, fractional-reserve banking, which began in , meant that the US dollar was no longer backed by gold and was steadily losing value. Satoshi was calling for something new, something better. Bitcoin was a digital currency secured by sound cryptographic principle. It caps the money supply to prevent inflation, relies on no centralized authority, and allows anyone to mine its supply or transact its coin through an anonymous P2P network. Contrarily, some bitcoiners feel that the encoded message only serves as proof that the genesis block was mined on January 3, These details were discovered by data scientists because the 48 machines hashed a different set range of nonces so that the hash work was not duplicated.
This behavior creates a unique saw pattern in nonce data analysis. It also seems that Patoshi may have intentionally slowed down the block pace in the first years by intermittently unplugging mining machines. This allowed room for other miners to join the network and receive BTC rewards. Hal Finney and Martii Malmi, among others, also report participating in mining blocks alongside Satoshi in the beginning years.
These early miners also joined coins so that they could sell them to other bitcoiners. For instance, 60, BTC, worth only a few dollars in , took over a week to mine. So rather than give a buyer over a thousand single wallets with one 50 BTC coinbase reward in each, bitcoin was consolidated into new wallets.
The bitcoin that Satoshi mined up to block 54, was sent to wallets which remain untouched today. Bitcoiners continue to make small donations to these wallets as coin burns. According to Whale Alert the estimated combined value of these wallets is 1,, bitcoin. This would make Satoshi the 23rd richest person in the world according to Forbes.
But, Nakamoto has good reason not to collect the coin. For instance, individuals who designed or used alternative currencies before Satoshi were punished. Similarly, Bitcoin was the main currency used in the infamous Silk Road, a digital black market place from
