[Farcast] @vitalik.eth This is one approach; perhaps people will opt to instead do ZK + ZK + OP tiebreak, or ZK + ZK + security council tiebreak. I have no strong opinions here, I care about the underlying goal, which is to be fast (in the normal case) and secure. With such proof systems, the only remaining bottleneck to fast settlement becomes the gas cost of submitting proofs onchain. This is why short term I say once per hour: if you try to submit a 500k+ gas ZK proof (or a 5m gas STARK) much more often, it adds a high additional cost. In the longer term, we can solve this with aggregation: N proofs from N rollups (plus txs from privacy-protocol users) can be replaced by a single proof that proves the validity of the N proofs. This becomes economical to submit once per slot, enabling the endgame: near-instant native cross-L2 asset movement through the L1. Let's work together to make this happen.
