Bridges are very complex and have under-explored security issues. The issue we are focused on with withdrawing from L2, which requires L1 to be absolutely sure of what occurred on L2 (finality was reached) and current proposals like Offchain Lab’s Arbitrum require 1 week for finality. In this talk, we discuss the three designs for “fast” withdraws that allow a user to move Layer 2 to Layer 1 instantly, while a counter-party takes the risk that the withdraw will not finalize.
