Unichain, Uniswap's DeFi-focused Layer 2 built on the OP Stack, is scheduled to activate the Holocene Network Upgrade on its testnet on December 18, 2024, at 22:00 UTC. The upgrade introduces Holocene Block Derivation, MIPS Contracts, and EIP-1559 Configurability, designed to improve functionality, performance, and scalability. The Holocene Block Derivation update simplifies the block derivation pipeline, optimizing worst-case performance for the Fault Proof System and improving cross-network interoperability. To ensure compatibility with the upgrade, node operators must update their op-node and op-geth software and properly configure the activation date.
