[GOAT Network Launches BitVM2 Testnet V3, Achieving Verifiable BTCFi Security] Foresight News reports that Bitcoin-native zkRollup project GOAT Network has officially launched the GOAT BitVM2 Testnet V3. This testnet adopts BitVM2 technology as the ultimate arbitration layer, aiming to enable Bitcoin to participate in financial activities without relying on custodians, committees, or multi-signature trust assumptions. Its core architecture leverages zero-knowledge validity proofs to ensure execution correctness and anchors the sequencing results on the Bitcoin mainnet, with withdrawals and disputes ultimately adjudicated by Bitcoin mainnet rules. Testnet V3 features key optimizations such as off-chain execution, Bitcoin-anchored sequencing, and Bitcoin-adjudicated withdrawal and dispute mechanisms. Subsequently, it will introduce BitVM2-GC to significantly reduce challenge costs, making security assumptions verifiable in practice for the first time. Additionally, GOAT Network has built a complete technology stack that includes Type-1 zkEVM, a decentralized sequencer, and its self-developed zkVM proof engine, Ziren.
