Over the past few months this work has evolved in multiple stages:
- A longer document describing various options: EOFv2 Design Space - HackMD
- A two-staged rollout plan: EOFv1.1 aka EOF rollout Cancun+Prague - HackMD
- And now a unified specification covering “EOFv2”: "Mega EOF Endgame" Specification - HackMD
There’s more discussion on this at: EVM Object Format (EOF)
