Odaily Planet Daily News: Coinbase engineer Roberto Bayardo proposed a Fjord network upgrade for OP Stack. The upgrade includes the introduction of EIP-7212, which uses the secp256r1 elliptic curve for secure and efficient signature verification, greatly reducing the gas cost of smart wallet applications. In addition, the upgraded version also uses Brotli compression technology to reduce data availability costs. EIP-7212 has been implemented on Polygon, and other L2s such as Arbitrum and zkSync are expected to support it. The Fjord upgrade aims to further reduce the overall transaction fees on the OP Stack chain. The upgrade is scheduled to be implemented on July 10, 2024, and is currently awaiting approval from the Optimism Governance Committee.
