What is Ethereum?
Ethereum is a decentralized blockchain platform that allows developers to build and deploy smart contracts and decentralized applications (dApps). It was proposed by Vitalik Buterin, a programmer and cryptocurrency researcher, in late 2013, and the Ethereum network officially launched on July 30, 2015.

Key features of Ethereum include:
Smart Contracts: Ethereum introduced the concept of smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. Smart contracts automatically enforce the terms of the agreement when predefined conditions are met, eliminating the need for intermediaries and facilitating trustless transactions.
Decentralized Applications (dApps): Ethereum enables the development and deployment of decentralized applications (dApps) on its blockchain. These dApps can range from financial applications, such as decentralized exchanges (DEXs) and lending protocols, to gaming, identity management, supply chain tracking, and more.
Ethereum Virtual Machine (EVM): The Ethereum Virtual Machine is a Turing-complete runtime environment that allows smart contracts to be executed on the Ethereum network. It provides a sandboxed environment for executing code in a deterministic and secure manner across all nodes in the network.
Ether (ETH): Ether is the native cryptocurrency of the Ethereum network and is used to facilitate transactions, pay for computational services (gas fees), and incentivize network participants, such as miners and validators. Ether is also traded on cryptocurrency exchanges and can be used as a store of value or medium of exchange.
Proof of Stake (PoS): Ethereum is in the process of transitioning from a proof-of-work (PoW) consensus mechanism to a proof-of-stake (PoS) mechanism with the Ethereum 2.0 upgrade. PoS aims to improve scalability, security, and energy efficiency by replacing miners with validators who are chosen to create new blocks and validate transactions based on the amount of ether they hold and are willing to lock up as collateral.
Ethereum has become one of the most prominent platforms for blockchain development and innovation, with a vibrant ecosystem of developers, projects, and communities building on top of its network. It has played a significant role in the growth of decentralized finance (DeFi), non-fungible tokens (NFTs), and other blockchain-based applications and use cases.
