It had been a long time coming.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-are-pos-and-pow\"><span class=\"ez-toc-section\" id=\"What_are_PoS_and_PoW\"><\/span>What are PoS and PoW?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a href=\"https:\/\/metaschool.so\/blockchains?ref=Article&amp;utm_source=Blog_Organic\">Blockchains<\/a> essentially work through ledgers. These ledgers are like huge registers or spreadsheets, if you will, that are used to do record-keeping of all the transactions.&nbsp;<\/p>\n\n\n\n<p>There are also nodes in a blockchain. These nodes are great in number and it is important for all of them to have a consensus. Some use the PoW system and some use the PoS system.<\/p>\n\n\n\n<p>PoW is where you have miners, individuals, who use energy, electricity, coding, and mathematics to do the needful. Whereas, in PoS, it is more of a <a href=\"https:\/\/metaschool.so\/articles\/staking-meaning\/\">staking<\/a> game.<\/p>\n\n\n\n<p>With PoW, there is an exorbitant amount of energy and computational power that is used. PoW also involves competition which sometimes increases the possibility of a big chunk of <a href=\"https:\/\/metaschool.so\/articles\/block-meaning-blockchain\/\">blocks<\/a> being owned by a certain miner, jeopardizing the security of a blockchain.<\/p>\n\n\n\n<p>Thus, the <a href=\"http:\/\/metaschool.so\/blockchains\/ethereum?ref=Article&amp;utm_source=Blog_Organic\">Ethereum blockchain<\/a> decided to shift.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-did-the-merge-take-so-long\"><span class=\"ez-toc-section\" id=\"Why_did_the_Merge_take_so_long\"><\/span>Why did the Merge take so long?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a href=\"https:\/\/articles.metaschool.so\/vitalik-buterin-ethereum-profile\/\">Vitalik Buterin<\/a> and other Ethereum core members had planned the merge for a long time but it was delayed for more than 6 years. This was due to engineering complexities and billions of dollars at risk. Once it was achieved, it was considered a massive milestone in blockchain history.<\/p>\n\n\n\n<p>The Merge was the joining of Ethereum\u2019s already established execution layer with its new PoS consensus layer which is called The <a href=\"https:\/\/ethereum.org\/en\/upgrades\/beacon-chain\/#:~:text=The%20Beacon%20Chain%20was%20the,proof%2Dof%2Dwork%20Ethereum.\" target=\"_blank\" rel=\"noopener\">Beacon Chain<\/a>.<\/p>\n\n\n\n<p><em><strong>To understand layers better, read the following:<\/strong><\/em><\/p>\n\n\n\n<p><a href=\"https:\/\/articles.metaschool.so\/plasma-chain-ethereum-blockchain\/\"><em><strong>Plasma chain<br><\/strong><\/em><\/a><a href=\"https:\/\/articles.metaschool.so\/layer-1-blockchain\/\"><em><strong>Layer 1<br><\/strong><\/em><\/a><a href=\"https:\/\/articles.metaschool.so\/layer-2-crypto\/\"><em><strong>Layer 2<\/strong><\/em><\/a><\/p>\n\n\n\n<p>It happened in a two-step process called (1) Bellatrix and (2) Paris.<\/p>\n\n\n\n<p>Bellatrix was the process of network update in the consensus layer while Paris was the execution layer that helped transition from the (PoW) to the (PoS) consensus mechanism.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"some-amazing-benefits-of-the-ethereum-merge\"><span class=\"ez-toc-section\" id=\"Some_amazing_benefits_of_the_Ethereum_Merge\"><\/span>Some amazing benefits of the Ethereum Merge<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>It will increase the efficiency of the Ethereum Blockchain and PoS will help decrease the energy consumption of the Ethereum network.<\/li><li>In PoW, it was costly for individuals to stake their ETH as it used to include the purchase of hardware and power supply.

It is a process that breaks down data into smaller shards to increase the speed of transactions in a blockchain.
