Ethereum is a decentralized, open-source blockchain system that features smart contract functionality. It is the second-largest cryptocurrency platform by market capitalization, after Bitcoin.


Ethereum enables developers to build and deploy decentralized applications (Dapps) and is widely used for ICOs. Its native cryptocurrency, Ether (ETH), is used to compensate participating nodes for computations performed. Ethereum’s versatility and programmability have made it a foundational component of the DeFi and NFT (Non-Fungible Token) sectors.
