Our article yesterday discussed the latest release of @ GOATRollup Economic Brown Book 2.0. GOAT Network Economic Brown Book 2.0 proposes innovative economic design solutions to address the long-standing incentive imbalance and security bottlenecks in the Bitcoin Layer2 ecosystem. The core improvement is the "universal operator rotation" mechanism, where all nodes regularly rotate roles to achieve a long-term balance between revenue and costs. Nodes no longer assume a fixed single role, which not only reduces the participation threshold for small and medium-sized nodes, but also significantly improves the decentralization level of the network. In addition, GOAT has introduced two interest earning token models, yBTC and pBTC. Users can obtain yBTC by staking Bitcoin, which can be further divided into pure gold tokens pBTC and yToken representing future income rights. This design releases liquidity and establishes for the first time a liquidity staking asset market similar to Ethereum within the BTC ecosystem. In terms of security, GOAT has also innovatively proposed a "multi round challenger mechanism", which significantly shortens the transaction challenge cycle (from 14 days to less than 1 day), improves fraud detection efficiency and user experience. What is everyone's opinion on the innovations of GOAT Network? Welcome to discuss together in the comment section!
