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.

A pre-image oracle is a way to lookup any piece of data (pre-image) by its hash. While this sounds impossible (and in the general case is) it is possible to write code assuming such a thing exists if it operates in a context where execution cannot continue unless the pre-image is provided by an external party.
