ChainCatcher Message, GOAT Network officially releases GOAT BitVM2 Testnet V3, taking a key step towards the implementation of native Bitcoin zkRollup. This testnet uses Bitcoin as the final arbitration layer, aiming to enable BTC to participate in real financial activities without relying on custodians, committees, or multi-signature trust assumptions.
Unlike most BTCFi solutions that depend on custodians or majority honest assumptions, GOAT BitVM2 uses the BitVM2 mechanism to allow error declarations or malicious behavior to be challenged in extreme cases, with final arbitration based on Bitcoin’s mainnet rules.
Testnet V3 features key optimizations such as off-chain execution, Bitcoin-anchored ordering, and dispute resolution mechanisms governed by Bitcoin. It will later introduce BitVM2-GC to significantly reduce challenge costs, making security assumptions practically verifiable for the first time.
