Ethereum

Ethereum: Aimed at being a decentralized platform for building applications. It allows developers to create smart contracts and decentralized applications (DApps) that can execute automatically when certain conditions are met.

Ethereum: Features a more complex and flexible programming language (Solidity) that enables the creation of smart contracts. This allows for a wide range of applications beyond simple transactions.

Ethereum: Initially also used PoW but has transitioned to Proof-of-Stake (PoS) with Ethereum 2.0, which aims to improve scalability and reduce energy consumption.

Ethereum: Has a vibrant and active developer community that continuously innovates and builds new applications, making it a hub for decentralized finance (DeFi), non-fungible tokens (NFTs), and other blockchain-based solutions.
