GOAT Network launches BitVM2 Testnet V3, BTCFi security achieves verifiability

Foresight News reports that the Bitcoin-native zkRollup project GOAT Network has officially launched the GOAT BitVM2 Testnet V3. This testnet adopts BitVM2 technology as the final arbitration layer, aiming to enable Bitcoin to participate in financial activities without relying on custodians, committees, or multi-signature trust assumptions. Its core architecture uses zero-knowledge validity proofs to ensure execution correctness, with the ordering results anchored on the Bitcoin mainnet, and withdrawals and disputes ultimately resolved by Bitcoin mainnet rules.

Testnet V3 features key optimizations such as off-chain execution, Bitcoin-anchored ordering, and dispute resolution and withdrawal mechanisms governed by Bitcoin. It will later introduce BitVM2-GC to significantly reduce challenge costs, making security assumptions practically verifiable for the first time. Additionally, GOAT Network has built a complete technical stack including Type-1 zkEVM, a decentralized ordering service, and its proprietary zkVM proof engine Ziren.
