In very simple terms, we can say that <strong>if a system is \u201cdecentralized\u201d, then its control and\/or its components are distributed (split)<\/strong> between several parties. In theory, there\u2019s not a single point of failure, and there\u2019s not a single leader either.<\/p>\n\n\n\n<p>In the software world (which includes cryptocurrencies), decentralization can be applied to numerous platforms at different levels. The computer scientist and entrepreneur Rohit Khare defines this complicated concept <a href=\"http:\/\/isr.uci.edu\/projects\/pace\/decentralization.html\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">de esta manera<\/a>:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>\u201cA decentralized system is one which requires multiple parties to make their own independent decisions. In such a decentralized system, there is no single centralized authority that makes decisions on behalf of all the parties. Instead, each party, also called a peer, makes local autonomous decisions towards its individual goals which may possibly conflict with those of other peers. Peers directly interact with each other and share information or provide service to other peers.\u201d<\/p><\/blockquote>\n\n\n\n<p><strong>Now, as he mentions, decentralization is kind of chaotic if the peers have conflicts<\/strong> for a lack of consensus rules. Open decentralized systems, in which everyone can participate without any requirements (again, such as <a href=\"https:\/\/alfacash.blog\/2020\/08\/18\/what-is-cryptocurrency-why-should-care-reasons\/\" target=\"_blank\" rel=\"noreferrer noopener\">CRIPTOMONEDAS<\/a>), can lead to welcome malicious peers who will attack the entire network or its participants. For example, malware inside files shared via P2P file-sharing apps.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"614\" src=\"https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/blockchain-3448529-1024x614.jpg\" alt=\"Decentralization-cryptocurrencies-P2P-sharing\" class=\"wp-image-9257\"\/><\/figure><\/div>\n\n\n\n<p>For Rohit Khare, there are mainly <a href=\"http:\/\/isr.uci.edu\/projects\/pace\/trustmgmt.html\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">two ways<\/a> to prevent attacks in a decentralized system: a layer of reputation or a layer of credentials for every peer. <a href=\"https:\/\/alfacash.blog\/2020\/08\/30\/dummies-what-is-blockchain-how-it-works\/\" target=\"_blank\" rel=\"noreferrer noopener\">cadena de bloques<\/a> structures go further, though. To achieve consensus among all participants and do without the trust that we would put in centralized entities (such as companies or governments), special systems have been created with cryptography.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>A little about consensus and cryptos<\/strong><\/h2>\n\n\n\n<p><a href=\"https:\/\/alfacash.blog\/2020\/08\/20\/how-buy-bitcoin-simple-steps-nice-recipe\/\" target=\"_blank\" rel=\"noreferrer noopener\">Bitcoin<\/a> and many others use Proof-of-Work (PoW). <a href=\"https:\/\/alfacash.blog\/2020\/08\/25\/cryptocurrency-mining-dummies-how-works\/\" target=\"_blank\" rel=\"noreferrer noopener\">This one<\/a> is an algorithm that develops a difficult math problem or riddle which must be solved to verify virtual transactions and create new coins. The device (usually the computer or <a href=\"https:\/\/alfacash.blog\/2020\/11\/21\/easy-crypto-miners-how-mine-cryptocurrencies-problems\/\" target=\"_blank\" rel=\"noreferrer noopener\">ASIC machine<\/a>) uses real-world electricity to solve this complex riddle. The new coins and transactions fees paid by users worldwide go as a reward for the miners \u2014the people who set up, maintain, and paid the needed machines and energy to make the system work.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"540\" src=\"https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/btc-k-3-1024x540.jpg\" alt=\"Decentralization-Bitcoin-mining-PoW\" class=\"wp-image-9223\"\/><\/figure>\n\n\n\n<p><strong>This way, a Bitcoin transaction is only valid if it\u2019s approved by numerous miners<\/strong> and registered as it on the blockchain. Therefore, if a malicious peer (miner) tries to validate a fraudulent transaction, the results for them would only be self-damaging. They\u2019d lose time and energy to no avail since the transaction won\u2019t be approved by other miners. So, to get some results, a malicious actor or group would need to control at least 51% of the total mining power \u2014which is known as a 51% attack.<\/p>\n\n\n\n<p>However, the more miners (power) inside a blockchain, the more expensive are theoretical attacks. For example, <a href=\"https:\/\/www.crypto51.app\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">el costo<\/a> to make a 51% attack on Bitcoin is $1.5 million <em>per hour<\/em>. The possible profits don\u2019t worth it because the system was designed exactly for that.<\/p>\n\n\n\n<p>Other popular cryptocurrencies, such as <a href=\"https:\/\/alfacash.blog\/2021\/09\/12\/cardano-vs-ethereum-which-one-better\/\" target=\"_blank\" rel=\"noreferrer noopener\">Cardano<\/a> (and Ethereum in <a href=\"https:\/\/alfacash.blog\/2020\/11\/14\/ethereum-2-new-features-prices-more-ethereum-chains\/\" target=\"_blank\" rel=\"noreferrer noopener\">the future<\/a>), use another cryptographic system: Proof-of-Stake (PoS). In PoS systems, the figure of the \u201cminer\u201d is replaced by the \u201cvalidator\u201d. This validator, which can be anybody who wants to, won\u2019t need any real-world resource. Instead, they lock a number of their own coins inside a special wallet. So, they can verify transactions and mint new coins, if necessary, and are rewarded for it.<\/p>\n\n\n\n<p>We\u2019ll back to these two systems and their decentralization (or not) ahead.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Types of decentralization<\/strong><\/h2>\n\n\n\n<p>To understand a bit more about our cryptocurrency world and its goal of decentralization, the Ethereum founder Vitalik Buterin prepared an analysis <a href=\"https:\/\/medium.com\/@VitalikButerin\/the-meaning-of-decentralization-a0c92b76a274\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">about this<\/a>. He considers that <strong>there are mainly three types of decentralization: architectural, political, and logical. <\/strong>Not all of them are present (or achievable) in cryptocurrencies since they implied different factors.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-1024x683.jpg\" alt=\"Solana-criptomoneda-flechas-tableta\" class=\"wp-image-8538\" srcset=\"https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-1024x683.jpg 1024w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-300x200.jpg 300w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-150x100.jpg 150w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-18x12.jpg 18w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-270x180.jpg 270w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-770x515.jpg 770w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-761x508.jpg 761w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-772x515.jpg 772w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-370x247.jpg 370w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-554x370.jpg 554w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-306x204.jpg 306w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-367x245.jpg 367w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-260x173.jpg 260w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280-87x58.jpg 87w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/01\/interactive-6300483_1280.jpg 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n\n<p>Architectural decentralization is about \u201chow many physical computers is a system made up of\u201d and \u201chow many of those computers can it tolerate breaking down at any single time\u201d. Political decentralization is about \u201chow many individuals or organizations ultimately control the computers that the system is made up of\u201d. And logical decentralization implies that the interface and data structures can be cut into several parts and still work.<\/p>\n\n\n\n<p>In this line, his conclusion is:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>\u201cBlockchains are politically decentralized (no one controls them) and architecturally decentralized (no infrastructural central point of failure) but they are logically centralized (there is one commonly agreed state and the system behaves like a single computer).\u201d<\/p><\/blockquote>\n\n\n\n<p>Of course, it\u2019s easily assumed that no central company or organization is behind blockchains, so, they\u2019re (in theory) politically decentralized. They\u2019re also architecturally decentralized because are formed by numerous miners or validators with their own devices worldwide. But they need to be logically centralized (work as one) to reach consensus, i.e., to agree that a transaction is valid. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why does decentralization matter?<\/strong><\/h2>\n\n\n\n<p>In the cryptocurrency world, decentralization is a core feature. <strong>Architectural decentralization is necessary to increase the security and stability of blockchains<\/strong>. For example, if a miner (or a bunch of them) goes offline for any reason, the system will still work with few to no consequences. That, indeed, already happened with Bitcoin when <a href=\"https:\/\/alfacash.blog\/2021\/09\/24\/bad-and-good-news-china-bans-bitcoin-twitter-adopts-it\/\" target=\"_blank\" rel=\"noreferrer noopener\">China completely banned<\/a> crypto mining last year.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/light-bulbs-1125016-1024x576.jpg\" alt=\"Decentralization-bitcoin-mining-China\" class=\"wp-image-9258\"\/><\/figure><\/div>\n\n\n\n<p>It&#8217;s believed that at least 65% of all Bitcoin miners were operating in China back then. Despite the irrevocable fact that this isn\u2019t much decentralized, when all those miners went offline amid the legal crisis, the network wasn\u2019t affected on a large scale. The users experienced a slower network for a few days while <a href=\"https:\/\/alfacash.blog\/2022\/02\/21\/where-are-bitcoin-miners-2022\/\" target=\"_blank\" rel=\"noreferrer noopener\">the miners moved<\/a>, and that was it. Architectural decentralization lets us have that advantage.<\/p>\n\n\n\n<p><strong>Political decentralization, for its part, let us have liberty over our money<\/strong>. If there\u2019s not a single party controlling the system behind cryptocurrencies, that means they\u2019re resistant to confiscation and censorship. The situation <a href=\"https:\/\/alfacash.blog\/2021\/03\/11\/top-countries-most-crypto-users-laws\/\" target=\"_blank\" rel=\"noreferrer noopener\">in Nigeria<\/a> during the last two years is a great example. The government decided to impede the fund\u2019s inflow from banks for the protesters since they can order the banks what to do.<\/p>\n\n\n\n<p>However, the protesters still could receive funds in cryptocurrencies. Even when the government banned crypto, it was perfectly possible to exchange crypto in external services or directly between people, because they can\u2019t control the blockchains (as they do with the banks).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Decentralization in blockchain systems<\/strong><\/h2>\n\n\n\n<p>At this point, we can say that <strong>most cryptocurrencies make a nice try, but they\u2019re not fully decentralized \u2014yet<\/strong>. We still can\u2019t assume that they\u2019re controlled by no one, as Buterin stated. Every cryptocurrency has different levels of decentralization (or not), but we can talk about Bitcoin first.<\/p>\n\n\n\n<p>As we mentioned before, 65% of the miners were concentrated in China until last year. Now, they\u2019re more distributed worldwide, but we still might have an issue with mining pools. There are over 15,000 Bitcoin nodes worldwide, but only four mining pools control over 59% of the hashrate.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"510\" src=\"https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-1024x510.jpg\" alt=\"Decentralization-Bitcoin-Mining-Pools\" class=\"wp-image-9251\" srcset=\"https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-1024x510.jpg 1024w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-300x149.jpg 300w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-150x75.jpg 150w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-18x9.jpg 18w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-270x135.jpg 270w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-770x384.jpg 770w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-1019x508.jpg 1019w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-900x448.jpg 900w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-370x184.jpg 370w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-554x276.jpg 554w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-306x152.jpg 306w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-260x130.jpg 260w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC-87x43.jpg 87w, https:\/\/alfacash.blog\/wp-content\/uploads\/2022\/03\/Bitcoin-Mining-Pools-share.-Source-BTC.jpg 1174w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption>Bitcoin Mining Pools share.

In DeepOnion (ONION), for example, a 51% attack would cost barely $1 per hour, and only one <a href=\"https:\/\/miningpoolstats.stream\/deeponion\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">grupo de miner\u00eda<\/a> (Zpool) already has over 55% of the total hashrate. Of course, it would be much easier to attack than Bitcoin and other more robust currencies.<\/p>\n\n\n\n<p><strong>The code is something else to consider.<\/strong> Talking about Bitcoin again, only six men have access to the code of the main Bitcoin implementation, <a href=\"https:\/\/alfacash.blog\/2020\/10\/22\/bitcoin-core-people-behind-bitcoin\/\" target=\"_blank\" rel=\"noreferrer noopener\">Bitcoin Core<\/a> \u2014used by 98% of the entire community [<a href=\"https:\/\/coin.dance\/nodes\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">CoinDance<\/a>].

The community would only take the last healthy version, make a fork (divide the network), and start from there again.<\/p>\n\n\n\n<p>Nevertheless, there\u2019s still a (tiny) chance that the Bitcoin Core code fails somehow, as it did <a href=\"https:\/\/www.coindesk.com\/markets\/2018\/09\/25\/in-wake-of-major-failure-bitcoin-code-review-comes-under-scrutiny\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">in 2018<\/a>. That\u2019s why the use of other implementations might be welcome.

Jeff Bezos, with $200 billion in net worth, gets 2 billion votes, and earns $2 billion from the government for voting.
