Overview

If a message is found to be invalid within a block during Message Graph resolution, the block must be re-executed with deposits only. This requires a few key modifications to the host:

  • Hints must be multiplexed over many L2 chains, giving the host context of which chain the hint is being sent for.
  • The host must be able to re-execute the deposit only block natively, populating the preimage store for the client program, since the optimistic block does not exist within the canonical chain. (? - maybe we can get away without this.)
  • When a deposit-only block is crafted due to invalid messages in the broader block, a special deposit transaction must be inserted containing the output root preimage within its calldata.
