The Ethereum development team recently finalized the technical plan for the Fusaka upgrade at the 214th execution layer core developer meeting (ACDE). After re-evaluation, the development team maintained the previously established scope of the upgrade, with the addition of only one proposal, EIP 7939.

The current Fusaka upgrade will include 12 Ethereum Improvement Proposals (EIP):
- PeerDAS peer data availability sampling ( EIP-7594)
- MODEXP limit setting ( EIP-7823)
- Transaction Gas limit adjustment ( EIP-7825)
- ModExp Gas cost increase ( EIP-7883)
- Limited to Blob parameter hard fork ( EIP-7892)
- Deterministic Proposer Future Mechanism ( EIP-7917)
- Blob base fee execution cost limit ( EIP-7918)
- Default gas limit set to XX0M(EIP-7935)
- secp256r1 curve supported precompiled ( EIP-7951)
- Contract code size measurement and limit increase ( EIP-7907 )
- RLP block size limit ( EIP-79340 1928374656574839201
- New opcode counting leading zeros )EIP-7939(

Several adjustments have also been made regarding technical implementation details: the contract code size limit has been reduced from the originally planned 256KB to 48KB)EIP-7907(; the Blob base fee parameter has been modified from 2^14 to 2^13)EIP-7918(; the maximum blob count parameter's attribution has been adjusted from EIP-7892 to EIP-7594.

According to the meeting's decision, if at least 3 consensus layer and 3 execution layer client teams are ready, the Fusaka Devnet 2 testnet will be launched on June 23. In addition, the meeting also discussed two new proposals for the future Glamsterdam upgrade, but due to insufficient testing data, some parameter adjustments will be postponed to the Devnet 3 phase.

This upgrade demonstrates Ethereum's ongoing technical roadmap for optimizing network performance and scalability, which is of great significance for improving the efficiency of blockchain infrastructure.
