Hash chaining: the hash chaining is to store and chain hash values of file contents. The hash value of the file content, also commonly referred to as the "digital fingerprint" of the file, may be obtained by hashing the file content. Such a way of chaining can only be used in connection with content chaining, if the file is tampered with, but not what the actual original text is.
The link is linked up: the link up-link is equivalent to the URI address added with the file on the basis of hash certification, so that two things of 'file address + file digital fingerprint' are stored on the blockchain, and the two things can mutually certify. The method is suitable for files, scanning pieces, pictures, audio and video files and the like, and is generally used in cooperation with content uplink and hash uplink.
