Problems solved by technology

However, in the process of judging whether there is a transaction for itself, the transaction receiver needs to use the private key of the transaction receiver to analyze and calculate all the transactions on the chain, resulting in a large amount of calculation for the transaction receiver to search, and the search process is time-consuming More, resulting in low transaction efficiency

Abstract

The present invention provides a block chain-based efficient transaction processing method, tracking method and device. The method includes: constructing an address list according to the address of the transaction receiver and n-1 other addresses; The temporary public key of the transaction funds, obtain the first parameter, obtain the second parameter, and obtain the intermediate parameters of each supervisor; obtain the first public key set, and obtain the second public key set; encrypt to obtain the random number ciphertext; The first set of public keys and the second set of public keys perform double-ring signatures to maintain positions, and obtain double-ring signature results; generate and issue transaction bills to the block chain. The device is used to perform the above method. The block chain-based efficient transaction processing method, tracking method and device provided by the embodiments of the present invention improve transaction efficiency.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a blockchain-based efficient transaction processing method, tracking method and device. Background technique [0002] In the existing technology, the privacy protection blockchain can use the method of changing the receiving address once, and the transaction initiator uses the key agreement protocol to generate a new receiving address for the receiving party to protect the privacy of the receiving party. Encryption can also be used to protect the privacy of the receiver. [0003] For an existing privacy-preserving blockchain system, the long-term address of each user includes a viewing key and a consumption key, and the transaction initiator uses the address information of the transaction receiver to generate a new temporary public key, which solves the problem of The generation of a new temporary public key, the query of the transaction receiver and the recovery of t...
