Learn about Ethereum

Ethereum is a decentralized, open-source blockchain with smart contract functionality. It ranks second only to Bitcoin in terms of market capitalization.

Ethereum was the first blockchain to offer smart contract functionality, which allows for the development of dApps on the blockchain.
It supports a vast network of companies and dApps built on the Ethereum platform, including NFT marketplaces, decentralized finance, and DAOs.
Ethereum is transitioning to ETH 2.0, a protocol that moves from Proof-of-Work to Proof-of-Stake, which reduces the environmental overhead of mining to zero.
