Firstly, encryption technology (such as public keys and private keys) is used to sign the inscribed  information, ensuring its integrity and authenticity. Secondly, consensus mechanisms in the blockchain network (such as proof of work, proof of stake, etc.) are utilized to verify the origin and sequence of the inscribed information. Based on this, blockchain contracts can ensure the consistency, security, and traceability of data, thus achieving the purpose of identifying the origin of the inscribed information."}]}],"pr":"995077e2bfbf505b317e4cefdc8cbf49affc976ad8ae7eb9441fc3e71b50af4f"}
