Ethereum Fusaka Upgrade: Key EIPs and Devnet Launch Details from 214th All Core Developers Meeting

Ethereum’s 214th All Core Developers Meeting highlighted critical updates on the upcoming Fusaka upgrade, encompassing a comprehensive suite of 12 Ethereum Improvement Proposals (EIPs). Key inclusions such as EIP-7594 (Peer Data Availability Sampling) and EIP-7939 (Leading Zero Counting Opcode) emphasize enhancements in network efficiency and transaction processing. The meeting also addressed significant parameter adjustments, including a reduction in the contract size limit from 256 KB to 48 KB under EIP-7907, and a recalibration of Blob base costs in EIP-7918, reflecting a strategic approach to optimize gas consumption and execution costs.

The development roadmap outlined the imminent launch of Fusaka Devnet 2 on June 23, mandating readiness from at least three client implementations across consensus and execution layers. Some feature rollouts have been deferred to Devnet 3, indicating a cautious and methodical testing phase to ensure network stability. Additionally, the Glamsterdam proposal introduced pivotal EIPs like EIP-7745 (TrustLog Index) and EIP-7919 (Pureth), further enriching Ethereum’s protocol capabilities and governance mechanisms.
