Ethereum Completes Fusaka Upgrade Enhancing Layer-2 Transaction Efficiency

Vitalik Buterin hailed the Fusaka upgrade as a milestone, introducing PeerDAS sharding and data sampling to cut Layer-2 fees by up to 60% and fill a decade-long scalability roadmap gap.

Summary

Ethereum’s Fusaka upgrade, celebrated by Vitalik Buterin, introduces PeerDAS for sharding and data availability sampling, potentially reducing Layer-2 transaction fees by 40%–60%. The update raises the block gas limit to 60 million, integrates blob parameter changes, and boosts Rollup data throughput eightfold. Developers will focus on ensuring stability and expanding Layer-1 gas capacity as part of the next improvement phase.

Terms & Concepts
  • PeerDAS: A data availability system enabling validators to verify small portions of blockchain data blobs instead of entire blobs, lowering bandwidth and computational demands.
  • Hard fork: A permanent divergence in a blockchain’s protocol, creating a new version that is incompatible with previous versions.
  • Layer-2: A secondary protocol built atop a blockchain to improve transaction throughput and reduce fees, while relying on the base layer for security.
