If you use TERMINAL_BLOCK_HASH (a block in the past) as an override for the merge, then you must have an activation epoch in the future at which point to activate this overrde. Otherwise, it would activate locally immediately for anyone that set the epoch and all nodes would be out of sync.

  • Add TBH_ACTIVATION_EPOCH
  • Ensure that if TERMINAL_BLOCK_HASH is overridden that the forkchoice ignores valid TTD terminal blocks (was a minor bug prior to this PR)

EDIT: Below was fixed by @hwwhww in ba582b3

Annoying note, I initially named this TERMINAL_BLOCK_HASH_ACTIVATION_EPOCH (I know, a verbose name), but setup.py would then see it as two vars and build the file as config.config.TERMINAL_BLOCK_HASH_ACTIVATION_EPOCH. I just changed the name for now to avoid this build error. BUT we generally don't use acronyms in our names so we either need to fix the build script or have a non-colliding var-name. Maybe -- TERMINAL_OVERRIDE_ACTIVATION_EPOCH

I fixed setup.py and restore it to TERMINAL_BLOCK_HASH_ACTIVATION_EPOCH.
