The invention provides a transaction method, an apparatus and a storage medium. The method comprises: generating signed transaction request information according to a second random number and sendingthe information to a node of a first block chain to generate a first contract on the first block chain; Acquiring a plurality of first hash values; Wherein the first hash value is a hash value of thefirst random number; Generating a second hash value according to the second random number and a plurality of first hash values; Sending a second random number and a plurality of first hash values to the first contract to trigger the first contract to enter an authentication state; Sending a second random number to the first contract for verification of the first contract, and locking the cryptographic currency of the request transaction by the second hash value after the verification is passed; The cryptographic currency being unlocked and distributed to the holder after the first contract verifies the identity of the holder of the first random number, and the collection request information being generated according to the first random number. The invention can authenticate the identity without signature and shortens the transaction time.
Description
technical field [0001] The present application relates to the technical field of internet finance, in particular to a transaction method, device and storage medium. Background technique [0002] At present, in the blockchain system, the method of signature verification using public-private key pairs is widely used for identity authentication. For example, when user A sends a piece of information that needs to pass identity authentication, he first needs to sign the information with the private key he holds to generate signature information, and then send the information and signature information to the authentication node, and the authentication node receives After the plaintext information and signature information, it is necessary to obtain the public key of user A, decrypt the signature information, and compare and verify it with the plaintext information, and finally complete the identity authentication. [0003] In the above identity authentication process, due to the ...
