By linking metadata to the blockchain, the authenticity, origin, and change history of data can be monitored and traced. The Notarization chain can help solve problems such as data tampering, forgery, and fraud, thereby improving the credibility of data. Meanwhile, the Notarization chain also contributes to the development of decentralized applications, such as in finance, supply chain, IoT, and other fields, enhancing system stability and security."}]}],"pr":"97cc762cf3af02811de910bdcf7030b3d390a783405e7d71f2cc4802b6ecd4ee"}
