Problems solved by technology

[0002] Most of the transactions of the existing blockchain systems will be publicly stored on the blockchain, and anyone can view the relevant information of the transaction on the blockchain. It will not be completely anonymous, and it will not be very good. To achieve untraceability (tracking the sender), and the existing transfer method can only be carried out in the form of UTXO to UTXO, or the transaction between the account model and the account model, and the transaction between the UTXO model and the account model is can't be achieved

Abstract

The invention provides a privacy transaction method, a system and a device. The method comprises the following steps: selecting a plurality of available first UTXOs in a privacy address according to atransfer amount; requesting a plurality of second UTXOs with the same quota from a block chain for each of the first UTXOs; selecting a plurality of available first UTXOs in the privacy address according to the transfer amount; and selecting a second UTXO with the same quota from the block chain. Wherein each of the second UTXOs is used for ring signature confusion of UTXOs of transfer transactions; the ring-signed first privacy transaction is sent to a privacy agreement for the privacy agreement to send assets of the same amount as the transfer amount to a recipient account. The ring-signedfirst privacy transaction is sent to a privacy agreement for the privacy agreement to send assets of the same amount as the transfer amount to a recipient account. The device ensures that the sender in the privacy transaction process is not traced through ring signature and confusion technology, and the invention realizes the transaction from UTXO model to account model, so that the block chain system can freely flow in the public account and the privacy account.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a private transaction method, system and equipment. Background technique [0002] Most of the transactions of the existing blockchain systems will be publicly stored on the blockchain, and anyone can view the relevant information of the transaction on the blockchain. It will not be completely anonymous, and it will not be very good. To achieve untraceability (tracking the sender), and the existing transfer method can only be carried out in the form of UTXO to UTXO, or the transaction between the account model and the account model, and the transaction between the UTXO model and the account model is Can't be achieved. Contents of the invention [0003] In view of the above defects or deficiencies in the prior art, it is desired to provide a private transaction method, system and device that can realize traceability and can transact from UTXO model to account model. ...
