BitVM2 Powers Trustless Bitcoin Bridges with Mainnet Verification
Robin Linus and co-authors present "Bridging Bitcoin to Second Layers via BitVM2," a significant advance toward trustless Bitcoin bridges. It introduces BitVM2-core for Turing-complete execution on Bitcoin with a 1-of-n trust assumption. The protocol supports light-client bridging and permissionless fraud-proofing, with a full challenge verification already tested live on mainnet. The paper also cites BitVMX and the TOOP protocol as related developments.

BitVM3: Efficient Computation on Bitcoin
A holy grail in blockchain infrastructure is a trustless bridge between Bitcoin and its second layers or other chains. We make progress toward this vision by introducing the first light-client based Bitcoin bridge.At the heart of its design lies BITVM2-CORE, a novel paradigm that enables arbitrary program execution on Bitcoin,combining Turing-complete expressiveness with the security of Bitcoin consensus.
