New Signature Translation Aims to Reduce BitVM3’s On-Chain Footprint
A new paper by Mikhail Sergeevitch, Konrad Staniec, David Tse, Nikhil Vanjani, and Robin Linus proposes a non-interactive translation of Winternitz signatures to Lamport signatures via secret sharing, aiming to shrink the on-chain footprint of BitVM3 and BABE.

Non-Interactive Translation of Winternitz Signatures to Lamport Signatures via Secret Sharing
BitVM2 brought arbitrary program execution to Bitcoin, yielding the first light-client-based bridge to its second layers and reducing the trust required at setup to a single honest participant. Its successors, BitVM3 and BABE, move the disputed computation off-chain into Garbled Circuits (GCs), cutting worst-case on-chain dispute costs by roughly three orders of magnitude and so opening participation beyond well-capitalized operators; BABE in turn cuts the off-chain storage and setup costs of BitVM3's garbled circuits by a comparable factor.
