PlatON algorithm scientist Xie Xiang said in a guest at the ChainNode live room (formerly Babbitt Live Room) tonight that privacy computing is a part of PlatON's ongoing research and provides a way to price data. PlatON has also been combining data and privacy to make new attempts. Currently, there is privacy AI (PAI), which combines privacy computing with machine learning. He also said that KeyShard is PlatON's new digital asset hosting service based on MPC (Secure Multi-Party Computing). In addition to fund hosting, it also cooperates with the verification node of PoS to provide node hosting security services.
