GOAT Network releases the Bitcoin ZK Rollup economic brown paper, proposing the first systematic model to address the incentive and verification mechanism challenges of Bitcoin Layer 2. This solution unifies the roles of orderers, provers, challengers, etc., through the 'Universal Operator Role Rotation Mechanism' and 'Multi-Round Challenge Mechanism', and reduces the withdrawal confirmation time from two weeks to within 24 hours. The new model introduces staking, rotation, and penalty mechanisms to ensure incentive compatibility and anti-malicious behavior capabilities.
