On October 22, at the 2021 Hangzhou yunqi conference, ant chain of ant group announced the upgrading of blockchain architecture. In the new architecture, privacy computing has become a native capability. Ant chain also launched a new blockchain network platform "fair" based on this new architecture. On "fair", privacy computing will be integrated into a single system with blockchain in factory settings. Yan Ying, technical director of ant chain, said that the combination of blockchain and privacy computing is not a simple 1 + 1 combination problem. To realize the transfer of data value, we need to think about the whole data life cycle. Ant chain proposed a native computing flow architecture for data value flow, and built a "fair" platform based on this. It is reported that the platform integrates three mainstream privacy computing technologies: multi-party secure computing (MPC), trusted execution environment (TEE) and federated learning (FL). In addition, through the deep integration of software and hardware technology, the independent secure computing hardware has been constructed and obtained CFCA security certification. The fully homomorphic hardware acceleration designed by the computing technology laboratory of Dharma Institute and Ali security Gemini laboratory has achieved more than 100 times the performance improvement.
