Ethereum News

Ethereum (ETH) was launched in 2015 by Vitalik Buterin and a team of co-founders as the world's first programmable blockchain, enabling smart contracts and decentralized applications (dApps) that extend far beyond simple peer-to-peer transactions. After transitioning from proof-of-work to proof-of-stake consensus through "The Merge" in 2022, Ethereum now processes transactions more efficiently while maintaining its position as the foundation for decentralized finance (DeFi) and Web3 innovation.

The Ethereum ecosystem encompasses thousands of decentralized applications, from DeFi protocols like Uniswap and Aave to NFT marketplaces, gaming platforms, and layer-2 scaling solutions like Arbitrum and Polygon. Developers, validators, and users interact within this programmable economy where ETH serves as both a digital currency and the fuel powering smart contract execution through gas fees.

CoinDesk covers all aspects of Etherum, from protocol upgrades and scaling developments to DeFi innovation and regulatory implications. Our reporters track everything from Ethereum's roadmap milestones and staking developments to the broader implications of programmable money and decentralized autonomous organizations.

Ethereum Activates Fusaka Upgrade, Aiming to Cut Node Costs, Speed Layer-2 Settlements

At the center of the upgrade is PeerDAS, a system that lets validators check small slices of data rather than entire “blobs,” reducing both costs and computational load for validators and layer-2 networks.
