Firstly, the decentralized architecture enables data to be stored not in a single location but across multiple nodes in a computer network, thereby reducing the risk of data loss. Each node maintains a complete copy of the digital ledger, eliminating the need for third-party service providers. Secondly, blockchain technology encrypts and validates data to ensure its  integrity and authenticity. Anyone can check whether the data has been modified, guaranteeing data security. Lastly, the full-chain evidence preservation mechanism makes the entire data processing process traceable, visualizable, and secure."}]}],"pr":"d0dc3b3c73537ece0a5d218d62573dd51987cc36569c59373b44dc3caeb212d4"}
