Block chain transaction settlement method and system, and related equipment

Abstract

The embodiment of the invention provides a block chain transaction settlement method and system and related equipment, which are used for realizing compatibility and transaction privacy protection ofvarious asset transactions on the same block chain. The method comprises steps that transaction information is acquired, the transaction information comprises an account transfer account, an account transfer amount, an account entry account and a target asset identifier, and the target asset identifier is one of multiple preset asset identifiers; whether the amount of the target asset corresponding to the target asset identifier in the transfer account is greater than the transfer amount or not is verified, and if so, privacy protection processing is performed on the transaction information togenerate private transaction data, so that the transaction information cannot be analyzed without private keys of both transaction parties; and the private transaction data is broadcast to a block chain for verification, and a transaction corresponding to the transaction information is executed after the verification is passed.

Description

technical field [0001] The present invention relates to the field of block chain technology, in particular to a block chain transaction settlement method, system and related equipment. Background technique [0002] In the application process of the blockchain, the demand for privacy information protection is getting more and more attention, such as hiding the privacy information such as the accounts of both parties to the transaction and the transaction amount of the user in the blockchain. More transaction privacy protection chains. In the transaction privacy protection chain, if there is a transfer transaction, except for the transaction issuer and the transfer receiver, no other third party can analyze the account information and transfer amount of both parties without the corresponding private key, and it is impossible to analyze the transactions on the chain. If the privacy transaction is related, then this transaction is a privacy protection transaction. [0003] The...

Problems solved by technology

[0003] The transaction privacy protection chain in the existing technology, such as the blockchain corresponding to Monero, uses Monero to conduct transactions, and other users cannot know the specific Monero transaction privacy information

However, Monero only supports the transaction privacy protection of one asset (Monero). When transferring cross-chain assets on the blockchain corresponding to Monero or trading Token assets generated by deploying contracts, only in Transaction accounting is carried out on public blocks, and transaction privacy protection for asset transfers other than Monero cannot be realized
