[Plain Language Guide] Ethereum’s Fusaka hard fork will be activated on December 3, 2025, marking a key step in network scaling. This upgrade enhances data availability through PeerDAS (EIP-7594), increasing Blob capacity by several times and significantly reducing Layer-2 Rollup transaction costs.
Additionally, it will raise the L1 gas limit to 60M, enhancing mainnet throughput. Fusaka also enables flexible Blob adjustments via the BPO fork and introduces secp256r1 support to optimize user experience. Overall, Fusaka brings greater scalability and lower fees to the Ethereum ecosystem, fostering closer collaboration between L1 and L2.
