1. Implementation of Transaction Read-Write Set Mechanism

We designed and implemented a read-write set data structure capable of effectively capturing and storing database operations during transactions. We integrated read-write set collection logic into system functions, ensuring accurate recording of all relevant database operations. We developed analytical tools to parse read-write set data, aiding in the identification of dependencies between transactions. Initial performance tests were conducted to evaluate the impact of the read-write set mechanism on overall system throughput.

2. Fixing Permission Verification for Ecosystem Data Table Operations

We conducted a comprehensive review of the existing permission verification logic, identifying potential security vulnerabilities. We redesigned and implemented a more stringent permission control mechanism to ensure that only authorized users and processes can operate on ecosystem data tables. We updated relevant API interfaces, incorporating additional permission verification steps. Extensive security testing was performed, including penetration testing and boundary condition testing.
