————————————————————
The discussion at the 212th Ethereum ACDE meeting centered around the progress of the Fusaka upgrade's Devnet and EIP proposals, reflecting Ethereum's ongoing efforts in pursuing performance optimization, stable fee markets, and enhanced resistance to DoS attacks.
📍 Let’s briefly summarize the core content of this meeting:
1️⃣ Progress of Fusaka Devnet
Devnet-0 is scheduled to launch on May 26, with most clients having completed integration, while updates for Nimbus and Lighthouse are still ongoing.
Hive tests found issues related to EIP-7823, and the development team is working on fixes.
Network partition testing showed insufficient stability and requires further evaluation.
Consensus Layer Specification v1.6.0-alpha.0 has been released, providing a foundation for subsequent testing.
2️⃣ Decision on Fusaka EIP scope
EIP-7825 (Transaction Gas Limit): Set a gas limit of 30 million to address DoS risks, balancing account abstraction and zkEVM compatibility, with community consensus, and future adjustments possible.
EIP-7918: Stabilizes the Blob market by anchoring the execution layer gas base fee, gaining support from Layer 2 teams, with constant parameters pending testing optimization.
3️⃣ Pending CFI proposal for Devnet-2
EIP-7907 (Contract Code Size Measurement): Widely supported, Nethermind will provide performance data in two weeks to assess the impact on state management.
EIP-7934 (RLP Block Size Limit): Controversies over responsibility allocation and computing resources have delayed finalization by two weeks.
EIP-7212 (secp256r1 Precompiled): Its importance is recognized, but it needs to be rewritten; Nico and Stokes are voluntarily promoting this, with decisions pending after modifications.
EIP-5920 (PAY Opcode): Community opinions are divided, and MEV compatibility needs review.
EIP-7762 (Increase Blob Gas Base Fee): Handed over to DFI route.
The Fusaka upgrade, as an important technological iteration for Ethereum, aims to optimize network performance and user experience through multiple EIPs. The launch of Devnet-0 marks the formal start of the testing phase, but the lag in updates for Nimbus and Lighthouse clients and the immaturity of network partition testing indicate that client coordination and network stability remain core challenges in development.
🔻EIP-7825 and network security
EIP-7825 sets a gas limit of 30 million to alleviate DoS risks caused by the continuous increase in gas limits. This mechanism is particularly important in current high throughput and complex transaction scenarios (like account abstraction and zkEVM).
However, setting the gas limit requires balancing safety and flexibility. Future adjustment space provides possibilities for adapting Layer 2 solutions and parallel execution but may also increase the complexity of development and testing. The community needs to closely monitor testing data to ensure that limit settings do not stifle innovative use cases.
🔻EIP-7918 (Blob Base Fee Mechanism) and the Layer 2 ecosystem
EIP-7918 stabilizes the Blob fee market by anchoring the execution layer gas base fee, demonstrating Ethereum's support for the Layer 2 ecosystem. Fluctuations in the Blob fee market significantly impact Rollup costs and user experience, and a stable fee mechanism helps enhance Layer 2 competitiveness.
Summary:
The meeting focused on the technical preparations for the Fusaka upgrade and EIP decisions, with the launch of Devnet-0 and consensus on EIP-7825 and EIP-7918 laying the groundwork for the upgrade, but issues regarding client synchronization, network testing, and some proposals' controversies still need to be resolved. Testing data and proposal revisions in the next two weeks will be crucial.
