GOAT Network Slashes BitVM2 Challenge Period to One Day, Boosting Bitcoin Scaling

The GOAT Network has announced the release of the GOAT BitVM2 whitepaper, marking a significant advancement in Bitcoin’s Layer 2 scaling solutions. The whitepaper, accessible at https://goat.network/BitVM2-whitepaper, introduces a major innovation: reducing the original BitVM2 14-day challenge period to just one day. This enhancement significantly improves the efficiency and security of Bitcoin zkRollups, addressing critical inefficiencies in the challenge process and paving the way for production-ready Bitcoin bridges.

One of the key highlights of GOAT BitVM2 is its accelerated dispute resolution, achieved through a multi-round challenger selection mechanism. This mechanism ensures effective finality in under one day, making it a pivotal step toward more robust and secure Bitcoin bridges. The protocol leverages Bitcoin as a settlement layer and a decentralized sequencer network for computation, supporting arbitrary-amount peg-outs via atomic swap under a 1-of-n honest node assumption. This positions GOAT BitVM2 as the most secure and efficient Bitcoin zkRollup protocol to date, driving broader adoption for scaling Bitcoin and converting it from a passive asset to an active asset.

The GOAT BitVM2 protocol incorporates several core innovations to enhance its functionality and security. These include cryptoeconomic security through dual-slashing mechanisms that deter operator misconduct and ensure robust protection against double-spend attacks. Additionally, the protocol features an incentive-aligned economy with fraud bounties that reward successful challengers, boosting participation and honest dispute resolution. The universal operator model rotates operators across roles such as sequencer, prover, and challenger, balancing costs and earnings to enhance decentralization and resilience. Furthermore, GOAT’s in-house zkMIPS is the fastest production-ready zkVM in the industry, optimizing proof generation, lowering costs, and ensuring verifiability.

GOAT Network is the first Bitcoin-native ZK Rollup engineered to deliver sustainable, native BTC yield. It combines in-house zkMIPS, a practical BitVM2 challenge model, and Bitcoin’s first Decentralized Sequencer network. The network addresses the real demand from BTC holders seeking transparent, risk-adjusted yield by introducing a full BTCFi product suite with APYs ranging from 2% to 30%+. This suite spans earning, trading, and playing, and its novel economic design enables trustless yield generation from gas fees, MEV, and miner rewards, eliminating reliance on unsustainable token farming.
