#TradeFiRevolution Ethereum is a decentralized blockchain platform that enables smart contracts and decentralized applications (DApps) without intermediaries. Proposed by Vitalik Buterin in 2013 and launched in 2015, it introduced the concept of programmable blockchain using its native cryptocurrency, Ether (ETH). Ethereum transitioned from Proof of Work (PoW) to Proof of Stake (PoS) with the Ethereum 2.0 upgrade, improving scalability, security, and energy efficiency. It powers decentralized finance (DeFi), non-fungible tokens (NFTs), and various Web3 innovations. Ethereum’s smart contract functionality allows developers to build diverse applications, making it a fundamental pillar of blockchain technology and the future of decentralized computing.
