By genesis block he meant\u00a0<strong>the first block of the Bitcoin blockchain.<\/strong><\/p>\n<p>The function of the first block was\u00a0<strong>crucial<\/strong>\u00a0to start the whole functioning of Bitcoin. This block was created on\u00a0<strong>January 3, 2009<\/strong>. This block was different from the rest of the blockchain, as it is unique in that it has no\u00a0<strong>previous<\/strong>\u00a0block. Therefore, the parameters for its creation were modified.<\/p>\n<p>It took\u00a0<strong>six days<\/strong>\u00a0from the creation of the Genesis block to the launch of the software. Although it was created on\u00a0<strong>January<\/strong>\u00a0<strong>3<\/strong>, Satoshi Nakamoto did not send the e-mail announcing Bitcoin until\u00a0<strong>January 9<\/strong>. In the genesis block, the first<strong>\u00a050 BTC were added to the Bitcoin network<\/strong>. These Bitcoins have not been transferred again due to certain features included in the code.<\/p>\n<p>A curious aspect about the genesis block of Bitcoin is that in the block code Satoshi Nakamoto left a message that read: \u201c<strong>Chancellor of the Times January 3, 2009 about to get a second bailout for the banks<\/strong>\u201c.<\/p>\n<p>This title belongs to the headline of an article published in<strong>\u00a0the London Times<\/strong>\u00a0on January 3, 2009 in which it was specified that the banks were receiving aid and rescue from the British government.<\/p>\n<p>Because of this, the newspaper headline has been the subject of countless<strong>\u00a0analyses<\/strong>\u00a0which has turned the physical copy of the newspaper into a\u00a0<strong>collector\u2019s<\/strong>\u00a0item. The main reason is that the headline is attributed to\u00a0<strong>Satoshi Nakamoto\u2019s idea<\/strong>\u00a0of creating a cryptocurrency that would not need the intervention of banks.<\/p>\n<p>The creator of Bitcoin never made any\u00a0<strong>statement<\/strong>\u00a0about this message, so the reason for the message on the block remains<strong>\u00a0unknown<\/strong>.<\/p>\n<div class=\"is-divider divider clearfix\"><\/div>\n<p>&nbsp;<\/p>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div id=\"image_331365992\" class=\"img has-hover x md-x lg-x y md-y lg-y\">\n<div class=\"img-inner dark\"><img fetchpriority=\"high\" decoding=\"async\" class=\"attachment-large size-large lazyloaded\" src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/07\/bloque-genesis-bitcoin.jpg\" sizes=\"(max-width: 914px) 100vw, 914px\" srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/07\/bloque-genesis-bitcoin.jpg 914w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/07\/bloque-genesis-bitcoin-300x205.jpg 300w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/07\/bloque-genesis-bitcoin-768x524.jpg 768w\" alt=\"bloque-genesis-bitcoin\" width=\"914\" height=\"624\" data-srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/07\/bloque-genesis-bitcoin.jpg 914w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/07\/bloque-genesis-bitcoin-300x205.jpg 300w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/07\/bloque-genesis-bitcoin-768x524.jpg 768w\" data-src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/07\/bloque-genesis-bitcoin.jpg\" data-sizes=\"(max-width: 914px) 100vw, 914px\" \/><\/div>\n<\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<p>&nbsp;<\/p>\n<div class=\"is-divider divider clearfix\"><\/div>\n<h2><span class=\"ez-toc-section\" id=\"how_does_a_genesis_block_work\"><\/span><strong>How does a Genesis Block work?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div class=\"is-divider divider clearfix\"><\/div>\n<p>The functions of block 0\u00a0<strong>differentiate<\/strong>\u00a0it from the rest of the blocks because it is the root of the whole chain and without it,\u00a0<strong>the system would not work.<\/strong>\u00a0Therefore, every blockchain has\u00a0<strong>its own genesis block<\/strong>\u00a0no matter what type of blockchain it is.

This is because each block can be traced back to a\u00a0<strong>previous block<\/strong>. As we already know, the\u00a0<strong>difficulty of mining<\/strong>\u00a0is increasing as the\u00a0<strong>number<\/strong>\u00a0of mined blocks increases.<\/p>\n<p>By this rule, the first block had a very<strong>\u00a0low<\/strong>\u00a0mining difficulty, specifically the difficulty was\u00a0<strong>level 1<\/strong>. To get an idea, the current difficulty of mining a bitcoin block is\u00a0<strong>23,137,439,666,498<\/strong>. Therefore, Satoshi Nakamoto was able to mine the genesis block\u00a0<strong>without competition<\/strong>\u00a0<strong>or difficulty<\/strong>. At that time\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-bitcoin\/\">bitcoin<\/a>\u00a0was nothing more than an\u00a0<strong>experiment<\/strong>\u00a0and even remained easy to mine until a year later when it started to catch on.<\/p>\n<p>Because block 1 was not mined until\u00a0<strong>six days after the initial block<\/strong>, there are numerous<strong>\u00a0theories<\/strong>\u00a0as to why it took Satoshi Nakamoto so long to mine it. Among these theories are that he was testing the\u00a0<strong>system and making sure it was working properly<\/strong>. However, there are other less technical theories that claim that Satoshi intended to recreate the story of\u00a0<strong>God\u2019s<\/strong>\u00a0rest after six days of creation.<\/p>\n<p>Another curiosity surrounding the Bitcoin genesis block is that although the Bitcoin genesis block contained\u00a0<strong>50 BTC<\/strong>, it has never been used. It may be\u00a0<strong>premeditated programming<\/strong>\u00a0or it may have been an\u00a0<strong>accident<\/strong>.<\/p>\n<p>The fact is that many users, in honor of Satoshi Nakamoto, have been\u00a0<strong>sending BTC<\/strong>\u00a0for years to the same address where the first 50 BTC were sent. This is a kind of\u00a0<strong>donation or tip<\/strong>, since users are aware that once the BTC have been sent to that address they cannot\u00a0<strong>get them back<\/strong>.<\/p>\n<p>Currently the Genesis Block for many users is the key to know the true identity of Satoshi Nakamoto. This is because only\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/who-is-satoshi-nakamoto\/\">Satoshi Nakamoto<\/a>\u00a0can access the private key associated with the first block and other blocks where the same signature is used to send a message.<\/p>\n<p>If any user capable of\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-are-the-blind-signatures\/\">signing<\/a>\u00a0the messages using the private key that was used in the initial block would appear, it would be solid evidence of Satoshi Nakamoto\u2019s\u00a0<strong>identity<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Tiempo de lectura:<\/span> <span class=\"rt-time\"> 4<\/span> <span class=\"rt-label rt-postfix\">minutos<\/span><\/span>You have probably heard about the\u00a0genesis block\u00a0when it comes to cryptocurrencies.
