Ethereum is a decentralized blockchain platform that lets anyone build apps, hold digital assets, or interact with others—without relying on a central authority. Launched in 2015, it goes beyond simple payments like Bitcoin by enabling “smart contracts,” which are programs that run automatically when conditions are met.
With Ethereum, users can access financial tools, games, marketplaces, and more—directly and securely. It’s censorship-resistant, open to anyone, and widely used for NFTs, decentralized finance (DeFi), and Web3 apps. Its native currency, ether (ETH), is used to pay for transactions on the network.
In 2022, Ethereum switched to proof-of-stake, cutting its energy use dramatically. Looking ahead, upgrades like sharding aim to boost speed and reduce fees, keeping Ethereum at the heart of the blockchain revolution.
