[0096] Further, based on the first embodiment of the blockchain processing method of the present invention, a second embodiment of the blockchain processing method of the present invention is proposed; before step S10, the blockchain processing method may include:
[0097] Generate the master public key matrix and the corresponding short base;
[0098] Based on the master public key matrix and the short base, generate master public key parameters;
[0099] Based on the ID information of the blockchain user node, a hash set and a message set are obtained through a hash algorithm;
[0100] Obtaining public parameters based on the independent matrix corresponding to the message set and the master public key matrix;
[0101] After running the master public key matrix, hash set, master public key parameters and Gaussian parameters, generate the private key corresponding to the ID information;
[0102] Obtaining a corresponding public key based on the private key;
[0103] Based ...

The present invention relates to the field of block chain, and discloses a block chain processing method, including: when receiving a transaction request from a receiver node, the sender node based on the transaction request and the first public-private key corresponding to the sender node Generate key image and transaction output value; generate ring signature information based on transaction request and key image; generate the first transaction order based on sender node’s historical transaction records, transaction output value, key image and ring signature information; Ring signature information and key image for miner verification; after the miner verification is passed, compete for a new block other than the block chain user node set where the sender node is located, so that the first transaction ticket is loaded in the block chain corresponding to the new block . The invention also discloses a block chain processing device, equipment and readable storage medium. Through the principle of key image and ring signature, the present invention is highly difficult to crack, can resist quantum computing attacks, and improves the security of the block chain.
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...
