One of the major breakthroughs brought by the combination of CLOUD and blockchain is that, while artificial intelligence is booming, false data and content are becoming increasingly serious problems. CLOUD can resist false information by using encrypted digital signatures and timestamps. Therefore, at the same time, CLOUD can improve the efficiency of blockchain networks, enhance their security, and unlock new features, such as allowing protocols to make decisions based on real-time data on the chain.The significance of CLOUD is that it enables blockchain to perceive the physical world, enable smart contracts to make decisions, and run AI models with privacy protection. This is a very promising technology....
