Block chain processing method and device, equipment and readable storage medium

Abstract

The invention relates to the field of block chains, and discloses a block chain processing method, which comprises the following steps: when a transaction request of a receiver node is received, enabling a sender node to generate a key image and a transaction output value based on the transaction request and a first public and private key pair corresponding to the sender node; generating ring signature information based on the transaction request and the key image; generating a first transaction list based on the historical transaction record, the transaction output value, the key image and the ring signature information of the sender node; performing miner verification on the ring signature information and the key image; and after the miner passes the verification, competing for the new block except the block chain user node set where the sender node is located, so as to enable the first transaction list to be loaded in the block chain corresponding to the new block. The invention further discloses a block chain processing device and equipment and a readable storage medium. Through the principles of secret key mapping and ring signature, the method is very high in cracking difficulty, can resist quantum computing attacks, and improves the safety of the blockchain.

Description

technical field [0001] The present invention relates to the technical field of blockchain (Block chain), in particular to a processing method, device, equipment and readable storage medium of blockchain in the financial industry. Background technique [0002] With the development of computer technology, more and more technologies (such as distributed, blockchain, artificial intelligence, etc.) are applied in the financial field. The traditional financial industry is gradually transforming into financial technology (Fintech). Technology applied to the financial industry. In the financial field, traditional blockchain solutions do not achieve true anonymity and guarantee the privacy and security of users' identities. Privacy leakage is a crucial issue. In the cryptocurrency payment system, research on protecting user identity privacy is an inevitable trend of current development. Therefore, this research content is the focus of the present invention's main discussion and re...
