Method and device for generating encrypted transfer transaction request and performing encrypted transfer

The invention aims to provide a method and a device for generating an encrypted transfer transaction request and carrying out encrypted transfer, a transaction initiator generates the encrypted transfer transaction request under a chain, and the request comprises an on-chain address of the transaction initiator, an on-chain address of a transaction receiver and an asset item of the transfer transaction. And the transaction receiving party receives the request and the output document, the change document and the rectifier document generated by the transaction initiator under the chain, verifies the request after obtaining the request on the chain, and updates the encrypted documents in the asset items of the transaction initiator and the transaction receiving party if the verification is passed. Compared with the prior art, the encrypted transfer transaction is completely generated under the chain, and is verified and executed on the chain, and in the whole process, the block chain does not contact the encrypt
