This is an article that helps such people to understand the ideology of blockchain as it summarizes its most important concepts.<\/span><\/p>\n<\/blockquote>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Firstly, it is important to know that blockchain is not a cryptocurrency, although a lot of people came to know about the technology after the success of bitcoin, the two are entirely different from each other. It is also not a programming language, neither is it a cryptographic codification or an AI or Machine Learning technology or a Python library or framework.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Blockchain is the name of a technology, and just as the name implies, it is a chain of block or group transactions that is distributed among users. It is an incorruptible record of transactions that do not depend on an external authority for it to validate the authenticity of data.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">The key function of the blockchain is its distributed security system and the 5 key characteristics or concepts that form the basis of the blockchain are the cryptographic hash, the immutable ledger, the p2p or peer to peer network, the consensus protocol and the block validation or mining. These characteristics will be further explained for easy comprehension.<\/span><\/p>\n<p>&nbsp;<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_32 counter-hierarchy counter-decimal ez-toc-grey\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\">Table des mati\u00e8res<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" style=\"display: none;\"><label for=\"item\" aria-label=\"Table des mati\u00e8res\"><i class=\"ez-toc-glyphicon ez-toc-icon-toggle\"><\/i><\/label><input type=\"checkbox\" id=\"item\"><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1'><li class='ez-toc-page-1 ez-toc-heading-level-1'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/satt-token.com\/blog\/archives\/1749\/#The_Cryptographic_Hash\" title=\"The Cryptographic Hash\">The Cryptographic Hash<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-1'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/satt-token.com\/blog\/archives\/1749\/#The_Immutable_Ledger\" title=\"The Immutable Ledger\">The Immutable Ledger<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-1'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/satt-token.com\/blog\/archives\/1749\/#The_Peer_to_Peer_P2P_Network\" title=\"The Peer to Peer (P2P) Network\">The Peer to Peer (P2P) Network<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-1'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/satt-token.com\/blog\/archives\/1749\/#The_Consensus_Protocol\" title=\"The Consensus Protocol\">The Consensus Protocol<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-1'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/satt-token.com\/blog\/archives\/1749\/#The_Block_Validation_or_Mining\" title=\"The Block Validation or Mining\">The Block Validation or Mining<\/a><\/li><\/ul><\/nav><\/div>\n<h1><span class=\"ez-toc-section\" id=\"The_Cryptographic_Hash\"><\/span><b>The Cryptographic Hash<\/b><span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Any data that transforms from a <\/span><b>Cryptographic function<\/b><span style=\"font-weight: 400\"> into a fixed-length string of numbers is called a <\/span><b>Hash<\/b><span style=\"font-weight: 400\">. Every input of the hash function produces a different output. If you use the same input, it produces the same output value. The blockchain creates a unique identity for every block of transactions with the hash value of the previous block added to each new block.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u00a0<img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-1752\" src=\"https:\/\/satt-token.com\/blog\/wp-content\/uploads\/2020\/02\/image.jpg\" alt=\"\" width=\"650\" height=\"390\" title=\"\" srcset=\"https:\/\/satt-token.com\/blog\/wp-content\/uploads\/2020\/02\/image.jpg 722w, https:\/\/satt-token.com\/blog\/wp-content\/uploads\/2020\/02\/image-300x180.jpg 300w\" sizes=\"auto, (max-width: 650px) 100vw, 650px\" \/><\/span><\/p>\n<h1><span class=\"ez-toc-section\" id=\"The_Immutable_Ledger\"><\/span><b>The Immutable Ledger<\/b><span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Every chain in the block of transactions works as an immutable digital ledger as every block of the chain contains the hash of the previous block, making it impossible to alter any block without affecting the entire chain.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<h1><span class=\"ez-toc-section\" id=\"The_Peer_to_Peer_P2P_Network\"><\/span><b>The Peer to Peer (P2P) Network<\/b><span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">No external or internal trust authority is needed by the blockchain because every data on the blockchain is distributed among all the users. Every user has his\/her own copy of the transactions and hashed blocks and the information of any new transaction is spread to the entire network. This makes it impossible for anybody to change the information on the chain as it is not stored by an individual but for the entire network of node users.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<h1><span class=\"ez-toc-section\" id=\"The_Consensus_Protocol\"><\/span><b>The Consensus Protocol<\/b><span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">For each time a node adds a new block, all the users will have to validate the block using a common protocol. This is typically done using the <\/span><b>proof of work <\/b><span style=\"font-weight: 400\">or <\/span><b>proof of stake method<\/b><span style=\"font-weight: 400\">. The nodes have to check that the new block meets the requirement of their proof method which includes the validation for all the transaction in the block. If the block is confirmed to be valid, it is added to the blockchain and new blocks will be created.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<h1><span class=\"ez-toc-section\" id=\"The_Block_Validation_or_Mining\"><\/span><b>The Block Validation or Mining<\/b><span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Mining simply means meeting the proof of work requirement needed to add a new block while other transactions are pending on the blockchain network. The proof of work usually requires that users create a block with restrictions on its Has code. The restrictions determine the difficulty of the network.<\/span><\/p>\n<p><span style=\"font-weight: 400\"> <img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-1753\" src=\"https:\/\/satt-token.com\/blog\/wp-content\/uploads\/2020\/02\/miner-du-bitcoin-et-cloud-mining-crypto-monnaie-1024x417.png\" alt=\"\" width=\"650\" height=\"265\" title=\"\" srcset=\"https:\/\/satt-token.com\/blog\/wp-content\/uploads\/2020\/02\/miner-du-bitcoin-et-cloud-mining-crypto-monnaie-1024x417.png 1024w, https:\/\/satt-token.com\/blog\/wp-content\/uploads\/2020\/02\/miner-du-bitcoin-et-cloud-mining-crypto-monnaie-300x122.png 300w, https:\/\/satt-token.com\/blog\/wp-content\/uploads\/2020\/02\/miner-du-bitcoin-et-cloud-mining-crypto-monnaie-768x313.png 768w, https:\/\/satt-token.com\/blog\/wp-content\/uploads\/2020\/02\/miner-du-bitcoin-et-cloud-mining-crypto-monnaie.png 1280w\" sizes=\"auto, (max-width: 650px) 100vw, 650px\" \/><\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400\">In conclusion, the blockchain is a technology that allows users to create a trustworthy and incorruptible system for recording any type of information or transaction. It does not require the assistance of an external or internal authority as every user relies on the technology itself by following a predefined rule to meet the consensus and ensure the authenticity of the data.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The blockchain is a term that has been flying around for years now, and although so many people her that term, not everyone is able to truly why the technology is talked about in every innovation even if they do [&hellip;]<\/p>\n","protected":false},"author":7,"featured_media":9576,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[611],"tags":[],"class_list":["post-1749","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-non-classe-en"],"_links":{"self":[{"href":"https:\/\/satt-token.com\/blog\/wp-json\/wp\/v2\/posts\/1749","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/satt-token.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/satt-token.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/satt-token.com\/blog\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/satt-token.com\/blog\/wp-json\/wp\/v2\/comments?post=1749"}],"version-history":[{"count":0,"href":"https:\/\/satt-token.com\/blog\/wp-json\/wp\/v2\/posts\/1749\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/satt-token.com\/blog\/wp-json\/wp\/v2\/media\/9576"}],"wp:attachment":[{"href":"https:\/\/satt-token.com\/blog\/wp-json\/wp\/v2\/media?parent=1749"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/satt-token.com\/blog\/wp-json\/wp\/v2\/categories?post=1749"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/satt-token.com\/blog\/wp-json\/wp\/v2\/tags?post=1749"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
