Execution Layer Meeting 243 [2026-08-13] | ACDE 243

This was Execution meeting #243 on August 13th focused on DevNet 8 updates and EIP proposals for the upcoming Glasgow (Glas) and Hagada forks. Barnabas reported that DevNet 8 (PlatoBerget) launched recently with growth activation planned for the following week, and the Glasgow fork would go live on Thursday at 7:50 AM UTC. Joachim presented final gas repricing results, confirming that broadcast limits could be safely raised to 200 million gas (three times the current limit) without requiring re-release of client specifications. The team discussed EIP 8061 for introducing a new gas limit configuration parameter to allow staged increases, which was approved by consensus layer clients. Kev discussed history expiry requirements for 2TB node operators, with most clients planning to drop history to approximately 5 months or fork minus one. The meeting then moved through 17 EIP proposals for Hagada, covering topics including linear page-based memory costing, refund removal, call-up code optimization, net gas metering for account changes, and precompiles for post-quantum cryptography.
