Ethereum, launched in 2015 by Vitalik Buterin and a team of developers, is the second-largest cryptocurrency by market cap and the leading blockchain for decentralized applications (dApps). Unlike Bitcoin, which was designed mainly as digital money, Ethereum enables developers to build programmable contracts known as smart contracts. These self-executing agreements allow the creation of decentralized exchanges, lending platforms, NFT marketplaces, and much more.

Ethereum has become the foundation of the decentralized economy. Its ecosystem drives innovation in DeFi, tokenization, gaming, and identity. With upgrades like Ethereum 2.0 and the transition to Proof of Stake, the network addresses scalability and sustainability challenges. Ethereum’s flexibility and developer community ensure its pivotal role in the ongoing expansion of Web3.
