That is why today we want to clarify this doubt and tell you\u00a0<strong>what Bitcoin Core is<\/strong>\u00a0and why it is so important for the first and most famous crypto in history.<\/p>\n<p>Bitcoin Core refers to the original and complete<strong>\u00a0implementation of the Bitcoin protocol.\u00a0<\/strong><\/p>\n<p>Bitcoin core is a full client application, a free open source\u00a0<strong>software<\/strong>,\u00a0<strong>fundamental to the functioning of the bitcoin network<\/strong>\u00a0and also a free Bitcoin wallet, called Bitcoin Core Wallet and used by nodes operating in the Bitcoin network to validate transactions.<\/p>\n<p>Initially, the software was that of Satoshi Nakamoto, released under the name \u2018Bitcoin\u2019 and later renamed \u2018Bitcoin Core\u2019 to distinguish it from the network name. For this reason it is also known as the \u2018Satoshi Client\u2019.<\/p>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<h2><span class=\"ez-toc-section\" id=\"history_of_bitcoin_core\"><\/span>History of Bitcoin Core<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>The birth of Bitcoin Core dates back to January 9, 2009<\/strong>, parallel to the release of version 0.1.0 by Satoshi Nakamoto.<\/p>\n<p>At this stage the Bitcoin software was in its primordial phase and was a very rudimentary application that nevertheless managed to run the first version of the Bitcoin network.<\/p>\n<p>Thanks to Nakamoto\u2019s great work, bitcoin software began to attract the attention of several developers and\u00a0<strong>the community of those who would be called\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-a-cypherpunk\/\">Cypherpunk<\/a>\u00a0gradually grew larger<\/strong>. This same group was in charge of improving the original software created by Nakamoto until it reached a more formal image with the publication of the code of version 0.1.5 in the development repository on GitHub.<\/p>\n<p>Since then, the development of Bitcoin Core grew exponentially and focused on resolving major issues and adding new features. This was mainly taken care of by Nakamoto and Gavin Andresen, a professional software developer.<\/p>\n<p>In 2010<strong>\u00a0Satoshi Nakamoto left the project in the hands of Gavin Andresen<\/strong>\u00a0and this decision made the quality of Bitcoin Software evolve in a very obvious way, as the new leader rewrote more than half of Nakamoto\u2019s original code.<\/p>\n<p>Another major contribution was made by\u00a0<strong>Amir Taaki<\/strong>\u00a0who on August 19, 2011 presented the<strong>\u00a0Bitcoin Improvements Proposal<\/strong>\u00a0scheme, known by its acronym\u00a0<strong>BIP<\/strong>.<\/p>\n<p>This proposal was inspired by the design of the well-known PEP (Python Enhancement Proposals) in order to include a similar structure that allowed developers from all over the world to freely introduce enhancements to the Bitcoin Core protocol, with the only condition that they had to demonstrate the usefulness and applicability of their enhancements.<\/p>\n<p>Later, developer Wladimir J. van der Laan created the official Bitcoin graphical interface,\u00a0<strong>Bitcoin-QT<\/strong>. Since then the development of Bitcoin Core started to progress without limits.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"bitcoind_segwit_and_lightning_network\"><\/span>Bitcoind, SegWit and Lightning Network<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>With the development of Bitcoin Core,\u00a0<strong>Gavin Andresen<\/strong>, having certain powers to manage the software code, wanted to improve the scalability of Bitcoin and therefore\u00a0<strong>proposed to increase the Bitcoin block size<\/strong>\u00a0but did not receive the expected support from the community. In 2014, after his attempt to change the code without community consensus, he was relieved of his position and denied access to the development repository.<\/p>\n<p><strong>Thus the leadership of Bitcoin Core passed to Wladimir J. Van der Laan<\/strong>, an IT expert and cypherpunk from Amsterdam who, until recently, maintained the role of project leader, until announcing on January 21, 2021, that he would have started, for personal reasons, to cover a more secondary role in the development of Bitcoin Core.<\/p>\n<p>In 2014, after some attempted security breaches of the OpenSSL project, Van der Laan suggested changing the OpenSSL library, used in Bitcoin, to one of his own. Despite community disagreement, Van der Laan\u2019s proposal won and the\u00a0<strong>Bitcoin project officially abandoned the OpenSSL library to use its own library, today called \u2018Bitcoind\u2019.<\/strong><\/p>\n<p>In 2016, the bitcoin scalability problem was discussed again, an issue that led the community to seek an alternative solution and introduce\u00a0<strong>SegWit which prepared the network for an additional feature, the\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-the-lightning-network\/\">Lightning Network<\/a><\/strong>, which would have solved the scalability problem.<\/p>\n<p>This decision provoked a strong dissent that resulted in the division of the community that, until then, supported Bitcoin Core and in the birth of several projects such as Bitcoin Classic, Bitcoin Unlimited, Bitcoin XT and Bitcoin Cash.<\/p>\n<p>Fortunately the development of Bitcoin Core continues to grow incredibly and also BTC, the most important cryptocurrency in history, continues to develop excellently and is growing non-stop.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"features_of_bitcoin_core\"><\/span><strong>Features of Bitcoin Core<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div id=\"row-35392435\" class=\"row\">\n<div class=\"col small-12 large-12\">\n<div class=\"col-inner text-center\">\n<div id=\"image_1436000612\" 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\/05\/Qu%C3%A9-es-Bitcoin-Core2.jpg\" sizes=\"(max-width: 768px) 100vw, 768px\" srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/05\/Qu\u00e9-es-Bitcoin-Core2.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/05\/Qu\u00e9-es-Bitcoin-Core2-300x205.jpg 300w\" alt=\"Qu\u00e9-es-Bitcoin-Core\" width=\"768\" height=\"526\" data-srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/05\/Qu\u00e9-es-Bitcoin-Core2.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/05\/Qu\u00e9-es-Bitcoin-Core2-300x205.jpg 300w\" data-src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/05\/Qu\u00e9-es-Bitcoin-Core2.jpg\" data-sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p>As mentioned at the beginning, Bitcoin Core consists of\u00a0<strong>a \u201cfull node\u201d software<\/strong>\u00a0to fully validate the blockchain<strong>\u00a0and a bitcoin wallet.<\/strong><\/p>\n<p>Below we will show you all the features that characterize Bitcoin Core:<\/p>\n<ol>\n<li aria-level=\"1\">First of all, Bitcoin Core Software\u00a0<strong>allows you to download part or all of the Bitcoin blockchain<\/strong>, turning your computer into a complete node of the Bitcoin network;<\/li>\n<li aria-level=\"1\">The software is open source, which means that\u00a0<strong>anyone can review the code and suggest changes<\/strong>\u00a0in the development part;<\/li>\n<li aria-level=\"1\">Bitcoin Core<strong>\u00a0comes with its own library, called Bitcoind<\/strong>, and has a graphical interface that allows easy navigation or access to the wallet;<\/li>\n<li aria-level=\"1\">It allows the creation of<strong>\u00a0a highly secure wallet of any type<\/strong>\u00a0(single or\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-a-multi-signature-wallet\/\">multi-signature<\/a>), as it automatically generates a key tree that the user can access using a 12- or 24-word phrase based on the tree, called\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-the-seed-phrase-and-why-is-it-so-important\/\">security seed<\/a>.<\/li>\n<li aria-level=\"1\">Although the wallet\u00a0<strong>does not charge any fees<\/strong>, there are some costs that do apply to the user.
