Overview
Ferry that can be used to ship tokens between chains
Summary
A slower, simpler, but more secure method of bridging tokens.
Motivation
Too many bridge hacks from bugs, team rugs, anon devs, etc.
Risks of infinite mints.
Some chains have slow bridges (Arbitrum, Optimism, etc).
Benefits
Risk is capped by token amounts in bridge contracts. No risk of infinite mints.
Slower transactions give more time for bad batches to be caught and stopped, assuming they are not cancelled automatically by bots.
Crewmembers can pause contracts so any issues can be investigated.
Risks
Captain is tricked into proposing a batch with a false hash AND all crewmembers bots are offline/censured/compromised and no one disputes the proposal.
Reorgs on the source chain. Avoided, by only returning the transactions on the source chain that are at least one hour old.
Rollbacks of optimistic rollups. Avoided by running a node.
Operators do not have enough time to pause the chain after a fake proposal. Avoided by requiring a minimal amount of time between sending the proposal and executing it.
