For the hackathon at EthBogota the ChainSafe team developed a new bridge prototype we called Zipline. This bridge uses fault proofs, the technology behind optimistic rollups, to construct a bridge. But is this actually a good idea? This article investigates some potential issues but also some paths forward to a practical version of such a bridge construction.
