Wu said that he learned that BOB co-founder Alexei Zamyatin tweeted to share a new white paper on the second version of the Bitcoin Virtual Machine BitVM2 and the updated BitVM Bridge released with Bitcoin expansion developers. The white paper details the latest achievements in improving transaction efficiency within the Bitcoin network by improving transaction processing capabilities and, in some cases, updating encryption methods. The white paper states that the main goal of BitVM2 is to increase Bitcoin's transaction capacity without modifying Bitcoin's core code or principles such as decentralization. BitVM2 introduces a permissionless system that allows any user to question suspicious transactions. In addition, the white paper mentions improvements to the BitVM Bridge, focusing on reducing capital requirements and shortening asset lock-up periods, which support cross-chain between Bitcoin and Rollup.
