Ethereum Protocol Fellowship (EPF) Cohort 7 — Applications open until May 13

bal-devnet-3

View Source · Scraped May 9, 2026
bal-devnet-3 targets to launch 08 April 2026.
EL clients: please add flags to enable/disable BAL optimizations batch/parallel io and parallel execution.
EL clients: EIP-8037 will be using a hardcoded value for the cost per state byte of 1174. This aligns with a block gas limit of 100M, the value being set for the devnet. The cost per state byte value of 1174 will be a treated as a fork constant for this devnet and not depend on the block gas limit. For the next devnet we will use the full EIP variant where the cpsb will depend on the block gas limit.
