Ethereum's Fusaka upgrade is now live on mainnet after activating at epoch 411392 on December 3rd at 21:49 UTC.​

The upgrade implements 13 Ethereum Improvement Proposals (EIPs) that bring significant scaling and user experience improvements:

  • PeerDAS unlocks 8x data throughput for rollups, enabling cheaper blob fees and faster confirmations
  • R1 curve support enables mobile-native passkeys and simpler signatures for better wallet UX
  • Based pre-confirmations reduce transaction latency from minutes to milliseconds
  • Gas limit increase from 45M to 60M expands network capacity
  • New per-transaction gas cap of 2^24 requires developer attention

Key upcoming dates:

  • BPO1: December 9th
  • BPO2: January 7th

Community members continue monitoring the network for any issues over the next 24 hours following the successful activation.​
