GOAT BitVM2: A Practical Breakthrough in Bitcoin-Native zkRollups

GOAT Network ( @GOATRollup ) has taken BitVM2 and customized it into GOAT BitVM2, integrating it into a full zkRollup stack for Bitcoin-native finance. The Testnet V3, launched publicly on January 28, 2026, is the first production-grade deployment of BitVM2 in a zkRollup environment and the final testnet before mainnet.

This is not just a fork; GOAT Network has engineered significant enhancements to make BitVM2 usable for real BTC yields and DeFi.

Key Improvements in GOAT BitVM2:

Shortened Challenge Period: Reduces the standard 14-day window to under 1 day using Ziren proof networks, multi-round randomized challenges, and a decentralized sequencer for neutral transaction ordering.

Economic Model Integration: GOAT BitVM2 Introduces BTC rewards for users and penalizes malicious behavior, ensuring liveness and permissionless participation without custodians or federations.

Real-Time Proving: Off-chain execution with ZK proofs verifiable on Bitcoin, supporting features like peg-ins/outs, stable nodes, and Bitcoin-anchored authority.

BitVM2-GC Extension: Incorporates garbled circuits with DV-SNARK verifiers for 1000x lower on-chain fraud-proof data, sub-1-hour proving times, and costs under $4 bridging BitVM2's practicality with BitVM3's efficiency.
