It achieves tamper-proof and traceable management of digital assets by associating metadata (such as files, images, videos, etc.) with the data in the block. Each block on the Notarization chain contains a certain amount of metadata, which  is encrypted and hashed, and combined with other information in the block to form an immutable record. Therefore, the Notarization chain has become a reliable data storage and verification platform, which can be widely applied to the management, transaction, and protection of digital assets."}]}],"pr":"80cef83d1396c1976c8e330cb3e6995bb905681f5424bbadad1ac246e4ce56b6"}
