Most popular DeFi and NFT projects run on Ethereum.<\/p>\n<\/div>\n<div class=\"wp-block-text-wrappers-cards single_card\">\n<h2 class=\"card_label\">Who created Ethereum, and when?<\/h2>\n<p>The main creator and public face of Ethereum is <a href=\"https:\/\/forklog.com\/en\/news\/who-is-vitalik-buterin\">Vitalik Buterin<\/a>. He was born in 1994 in Kolomna, near Moscow. At the age of six he moved with his parents to Canada, where he still lives. From childhood he was keen on programming and computer science; at university he studied cryptography.<\/p>\n<p>In 2011 Vitalik Buterin became a co-founder of one of the first media outlets about <a href=\"https:\/\/forklog.com\/en\/news\/what-is-cryptocurrency-simply-put\">cryptocurrencies<\/a>\u2014Bitcoin Magazine.<\/p>\n<p>In 2013 he published Ethereum\u2019s <a href=\"https:\/\/ethereum.org\/en\/whitepaper\/\" target=\"_blank\" rel=\"noreferrer noopener\">whitepaper<\/a>\u2014a <a href=\"https:\/\/forklog.com\/en\/news\/what-is-blockchain-2\">blockchain<\/a> on which developers could create decentralised applications powered by smart contracts. Other co-founders included Gavin Wood, Charles Hoskinson, Anthony Di Iorio and Joseph Lubin.<\/p>\n<p>After the whitepaper, Buterin received a $100,000 grant from the Thiel Fellowship, created by entrepreneur Peter Thiel. He used this money to conduct an ICO. The token sale raised 31,550 BTC\u2014about $18.5m at the time.<\/p>\n<p>Ethereum\u2019s main network launched in the summer of 2015. Since its inception, the project\u2019s development has been overseen by the <a href=\"https:\/\/ethereum.org\/en\/foundation\/\" target=\"_blank\" rel=\"noreferrer noopener\">Ethereum Foundation<\/a>, a non-profit organisation registered in Switzerland.<\/p>\n<\/div>\n<div class=\"wp-block-text-wrappers-cards single_card\">\n<h2 class=\"card_label\">What are Ethereum\u2019s key features?<\/h2>\n<h3 class=\"wp-block-heading\">Smart contracts<\/h3>\n<p>Ethereum\u2019s chief distinction from Bitcoin was support for full-fledged <a href=\"https:\/\/forklog.com\/en\/news\/what-is-a-smart-contract\">smart contracts<\/a>\u2014computer programs that allow deals to be executed without a third party. In effect they are \u201cdigital contracts\u201d with pre-set terms that self-execute when conditions are met. This moves business operations onto the blockchain and reduces the \u201chuman factor\u201d. The use-cases for smart contracts are myriad.<\/p>\n<h3 class=\"wp-block-heading\">Virtual machine (EVM)<\/h3>\n<p>The EVM (<a href=\"https:\/\/forklog.com\/en\/news\/what-is-the-ethereum-virtual-machine-evm\">Ethereum Virtual Machine<\/a>) is a \u201cdistributed computer\u201d responsible for executing smart contracts. If Bitcoin\u2019s main function is recording transactions between accounts in a distributed ledger, the EVM can handle much more complex operations encoded in smart contracts (which, nonetheless, ultimately represent transfers between blockchain addresses).<\/p>\n<h3 class=\"wp-block-heading\">User-created tokens<\/h3>\n<p>Ethereum enabled users to issue their own tokens. For such tokens developers created the <a href=\"https:\/\/forklog.com\/en\/news\/what-is-the-ethereum-virtual-machine-evm\">ERC-20 standard<\/a>. These tokens derive value from utility within a particular application. Ethereum became the first popular blockchain for startups that monetised via native tokens.<\/p>\n<h3 class=\"wp-block-heading\">Non-fungible tokens (NFTs)<\/h3>\n<p>Ethereum also became popular as a blockchain for <a href=\"https:\/\/forklog.com\/en\/news\/what-are-nfts\">NFTs<\/a> thanks to the ERC-721 standard. These are non-fungible tokens, each of which encodes unique information\u2014an image or another file. An NFT is a unique digital item that cannot be reproduced. In 2022 <a href=\"https:\/\/forklog.com\/en\/news\/what-are-soulbound-tokens-and-how-do-they-differ-from-nfts\">soulbound tokens<\/a> also began to gain popularity.<\/p>\n<\/div>\n<div class=\"wp-block-text-wrappers-cards single_card\">\n<h2 class=\"card_label\">What is the ether (ETH) cryptocurrency?<\/h2>\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/forklog.com\/wp-content\/uploads\/ethereum2-1024x819.jpg\" alt=\"What is Ethereum (ETH)?\" class=\"wp-image-108109\" width=\"768\" height=\"614\" srcset=\"https:\/\/forklog.com\/wp-content\/uploads\/ethereum2-1024x819.jpg 1024w, https:\/\/forklog.com\/wp-content\/uploads\/ethereum2-300x240.jpg 300w, https:\/\/forklog.com\/wp-content\/uploads\/ethereum2-768x614.jpg 768w, https:\/\/forklog.com\/wp-content\/uploads\/ethereum2.jpg 1200w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><\/figure>\n<p>Ether (ETH) is the colloquial name for Ethereum\u2019s native cryptocurrency. It is needed to run decentralised applications and to pay transaction fees on the network.<\/p>\n<p>After The Merge was activated in September 2022, <a href=\"https:\/\/forklog.com\/en\/news\/what-is-staking-and-how-to-make-money-from-it\">staking<\/a> of ether began on Ethereum: holders of ETH can lock coins and earn income. However, withdrawing cryptocurrency from staking will be possible only after sharding is implemented\u2014this was expected during 2023. To participate in ether staking, you must run your own node (requiring hardware and 32 ETH) or use a centralised service such as Everstake, <a href=\"https:\/\/forklog.com\/en\/news\/what-is-lido\">Lido<\/a> or <a href=\"https:\/\/forklog.com\/en\/news\/what-is-binance\">Binance<\/a>.<\/p>\n<p>ETH is the second-largest digital asset by market capitalisation. As of late October 2022 the total value of all ether exceeded $192bn. The Ethereum price rose tenfold in less than two years: in July 2020 one coin cost $300, but by late 2021 its price had settled above $3,000. Ethereum can be bought on practically any cryptocurrency exchange.<\/p>\n<\/div>\n<div class=\"wp-block-text-wrappers-cards single_card\">\n<h2 class=\"card_label\">How did The DAO hack shape Ethereum\u2019s development?<\/h2>\n<p>Ethereum\u2019s first major crisis was the hack of The DAO. This <a href=\"https:\/\/forklog.com\/en\/news\/what-is-a-dao-decentralised-autonomous-organisation\">decentralised autonomous organisation (DAO)<\/a> sought to run an investment fund through member voting. The DAO was to operate via Ethereum smart contracts. Following an ICO in 2016, its founders raised $150m.<\/p>\n<p>In June 2016 a hacker exploited the project\u2019s smart contract and withdrew DAO tokens worth $50m. After that the Ethereum team conducted a hard fork to return the stolen funds to victims. Part of the community, disagreeing with this decision, continued the original chain, calling their project <a href=\"https:\/\/forklog.com\/en\/news\/what-is-ethereum-classic-and-the-etc-cryptocurrency\">Ethereum Classic<\/a>.<\/p>\n<\/div>\n<div class=\"wp-block-text-wrappers-cards single_card\">\n<h2 class=\"card_label\">Did token sales take off because of Ethereum?<\/h2>\n<p>In 2017 the cryptocurrency market began to soar and drew global attention. Retail investors started buying actively. Hundreds of projects tried to replicate Ethereum\u2019s success: they published whitepapers and conducted <a href=\"https:\/\/forklog.com\/en\/news\/what-is-an-ico-and-can-you-profit-from-it\">ICOs<\/a>. Thanks to the accessibility of ERC-20, anyone could issue a token.<\/p>\n<p>Activity peaked in the first quarter of 2018\u2014total proceeds were about $7bn. Public token sales then almost ceased: cryptocurrency prices began to fall, and authorities in various countries criticised token sales.<\/p>\n<p>Investor trust in ICOs fell because they became a popular tool for fraudsters.<\/p>\n<p>New token-sale formats gradually appeared: <a href=\"https:\/\/forklog.com\/en\/news\/what-is-an-initial-exchange-offering-ieo-and-how-does-it-differ-from-an-ico\">IEOs (Initial Exchange Offerings)<\/a>\u2014selling a project\u2019s tokens through a special service on an exchange\u2014and IDOs (Initial Decentralised Offerings), raising investment through <a href=\"https:\/\/forklog.com\/en\/news\/what-is-yield-farming\">asset farming<\/a>.<\/p>\n<\/div>\n<div class=\"wp-block-text-wrappers-cards single_card\">\n<h2 class=\"card_label\">How did Ethereum lead to DeFi\u2019s creation?<\/h2>\n<p>The emergence of decentralised finance (DeFi) owes much to Ethereum. In 2017\u20132018 several landmark projects on this blockchain gained popularity and led to the flowering of DeFi:<\/p>\n<ol class=\"wp-block-list\">\n<li><a href=\"https:\/\/forklog.com\/en\/news\/what-are-makerdao-mkr-and-the-dai-stablecoin\"><strong>MakerDAO<\/strong><\/a>. The first popular protocol that allows any user to issue the DAI <a href=\"https:\/\/forklog.com\/en\/news\/what-are-stablecoins\">stablecoin<\/a> against collateral in various cryptoassets. The protocol is governed by a DAO in which holders of the Maker (MKR) token can vote.<\/li>\n<li><a href=\"https:\/\/forklog.com\/en\/news\/what-is-compound-comp\"><strong>Compound<\/strong><\/a>. This project first applied liquidity pools for various cryptoassets. In addition, Compound held the first IDO in history for its users, distributing the COMP <a href=\"https:\/\/forklog.com\/en\/news\/what-is-a-governance-token\">governance token<\/a> via farming.<\/li>\n<li><a href=\"https:\/\/forklog.com\/en\/news\/what-is-uniswap-uni\"><strong>Uniswap<\/strong><\/a> \u2014 a <a href=\"https:\/\/forklog.com\/en\/news\/what-is-a-decentralised-exchange-dex\">decentralised exchange<\/a> for trading cryptocurrencies that first applied an automated market maker. It creates an order-book analogue and matches orders without a central order book. Uniswap became the first protocol with relatively fast on-chain trading.<\/li>\n<\/ol>\n<p>Today hundreds of DeFi projects with various functions are live, such as <a href=\"https:\/\/forklog.com\/en\/news\/what-is-aave\">Aave<\/a>, <a href=\"https:\/\/forklog.com\/en\/news\/what-is-curve\">Curve Finance<\/a>, <a href=\"https:\/\/forklog.com\/en\/news\/what-is-1inch\">1inch<\/a>, Balancer, dYdX, Notional and others. They use different technologies and blockchains, but Ethereum was the first.<\/p>\n<\/div>\n<div class=\"wp-block-text-wrappers-cards single_card\">\n<h2 class=\"card_label\">Does Ethereum have competitors?<\/h2>\n<p>The blockchain-platform model proved itself, and Ethereum became the leading crypto project alongside Bitcoin. But its main components did not change for several years, while the crypto industry moved on. The throughput for which the main blockchain platform was designed is no longer sufficient.<\/p>\n<p>Today Ethereum can process no more than 13\u201315 transactions per second (TPS), its network has repeatedly suffered overloads and delays, and <a href=\"https:\/\/forklog.com\/en\/news\/why-ethereum-fees-are-so-high-and-how-to-cut-them\">fees for transfers are consistently high<\/a>.<\/p>\n<p>Meanwhile, modern \u201cEthereum killers\u201d boast performance tens or hundreds of times higher. <a href=\"https:\/\/forklog.com\/en\/news\/what-is-tezos-xtz\">Tezos<\/a> exceeds 1,000 TPS, <a href=\"https:\/\/forklog.com\/en\/news\/what-is-polkadot-dot\">Polkadot<\/a> up to 3,000 TPS, <a href=\"https:\/\/forklog.com\/en\/news\/what-is-solana-sol\">Solana<\/a> up to 50,000 TPS.<\/p>\n<p>Each blockchain platform offers its own scalability solution\u2014the ability to increase throughput as load grows. For example, Solana uses an implementation of the Practical Byzantine Fault Tolerance consensus algorithm, and Polkadot consists of several interconnected blockchains.<\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\">\n<div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"\u0411\u043b\u043e\u043a\u0447\u0435\u0439\u043d \u0431\u0443\u0434\u0443\u0449\u0435\u0433\u043e | \u041f\u043e\u0434\u043a\u0430\u0441\u0442\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/yekH9iO7ByU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><figcaption>\u201cWhat the blockchain of the future will look like\u201d \u2014 a ForkLog channel broadcast on 24.10.2022<\/figcaption><\/figure>\n<p>However, higher scalability comes with drawbacks described by the <a href=\"https:\/\/forklog.com\/en\/news\/what-is-the-blockchain-trilemma\">blockchain trilemma<\/a>. It holds that of three key properties\u2014performance, security and decentralisation\u2014a decentralised network can simultaneously guarantee only two. Both Ethereum and its competitors are trying to overcome this, but there is no broadly accepted solution yet.<\/p>\n<\/div>\n<div class=\"wp-block-text-wrappers-cards single_card\">\n<h2 class=\"card_label\">How is Ethereum being developed?<\/h2>\n<p>Developers have devised several ways to increase Ethereum\u2019s throughput while reducing fees. One approach is <a href=\"https:\/\/forklog.com\/en\/news\/what-is-a-layer%e2%80%912-solution-in-blockchain\">Layer-2 solutions<\/a>.<\/p>\n<p>These are applications and frameworks deployed on top of the Layer 1 base chain. The additional \u201clayer\u201d lowers transfer fees and increases transaction speed.<\/p>\n<p>L2 solutions on Ethereum are implemented using rollups, which allow hundreds of Layer-2 transactions to be included in a single Layer-1 transaction. Examples include <a href=\"https:\/\/forklog.com\/en\/news\/what-is-arbitrum\">Arbitrum<\/a>, <a href=\"https:\/\/forklog.com\/en\/news\/what-is-optimism-op\">Optimism<\/a>, dYdX and <a href=\"https:\/\/forklog.com\/en\/news\/what-are-starknets-blockchain-and-cryptocurrency\">StarkNet<\/a>.<\/p>\n<p>Another direction is <a href=\"https:\/\/forklog.com\/en\/news\/sidechains-what-they-are-and-how-they-work\">sidechains<\/a>. These are \u201cparallel\u201d networks linked to the main blockchain, between which transactions can be conducted. An example of an Ethereum-compatible sidechain is Polygon PoS (one element of the <a href=\"https:\/\/forklog.com\/en\/news\/what-is-polygon-matic\">Polygon network<\/a>).<\/p>\n<\/div>\n<div class=\"wp-block-text-wrappers-cards single_card\">\n<h2 class=\"card_label\">What is Ethereum 2.0 (Eth2)?<\/h2>\n<p><a href=\"https:\/\/forklog.com\/en\/news\/what-is-ethereum-2-0\">Ethereum 2.0<\/a> (Eth2) is a major upgrade, announced back in 2017, intended to improve the platform\u2019s scalability through far-reaching architectural changes.
