||Ethereum is a decentralized blockchain platform that was launched in 2015 by Vitalik Buterin. It is a platform that enables developers to build decentralized applications (Dapps) using smart contracts, which are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. Ethereum is different from Bitcoin in that it is not just a digital currency but a platform for building decentralized applications. The platform has its own cryptocurrency called Ether (ETH), which is used to facilitate transactions and pay for fees on the Ethereum network. Ethereum has gained popularity for its ability to enable a wide range of applications, including decentralized finance (DeFi), non-fungible tokens (NFTs), and more. Its flexibility and programmability have made it a popular choice for developers looking to build decentralized applications that can run autonomously without the need for intermediaries.
