Problems solved by technology

[0004] In the existing second-hand goods trading platform, there are the following problems: credit problem: there is a trust problem between the two parties in the transaction, the buyer may buy defective products at a high price, or may not receive the goods after payment, and the seller may encounter malicious returns after selling the product Efficiency issues: due to the low standardization of second-hand items, the process of reaching an agreement between the two parties is long, and the transaction time needs to be very long; platform issues: the platform intervenes as a third party, and it is not easy to monitor the transaction process

Embodiment Construction

[0012] The inventor of the present application found that in the existing blockchain network, after the client initiates a transaction, it will be broadcast to the network and wait for review. Other blockchain nodes in the network will package some transaction records waiting to be reviewed (in addition to information such as the hash value of the previous block), form a candidate block, and try to find a random number (nonce) string into blocks. When the hash (hash) result of the candidate block satisfies certain conditions, the block is legal in format, so that the block is a legal new block and can be added to the chain. The above-mentioned Proof Of Work (POW) algorithm requires blockchain nodes to perform a certain amount of calculations, which means that the computer needs to consume a certain amount of time, and the entire process is usually inefficient.

[0013] An embodiment of the present invention provides a transaction review method for a block chain network. The t...

Abstract

A transaction auditing method for a blockchain network, a computing device and a storage medium are disclosed, the transaction auditing method comprises: A, receiving a transaction request broadcast by a buyer node, the transaction request comprising an identifier of the buyer node and an identifier of a seller node; B, inquiring credit information of the buyer node and the seller node according to the buyer node and the seller node identifier; C, auditing the transaction request according to the credit information of the buyer node and the seller node; And D, in response to the fact that thetransaction request is audited successfully, forming a new block based on the transaction request, and writing the new block into a block chain account book of the block chain network. According to the technical scheme, the transaction efficiency and reliability between the buyer node and the seller node in the block chain network can be improved.

Description

technical field [0001] The present invention relates to block chain network technology, in particular to a transaction review method, computing equipment and storage medium for block chain network. Background technique [0002] Blockchain (Blockchain) network is an intelligent peer-to-peer network that uses distributed databases to identify, disseminate and record information, also known as the Internet of Value. Blockchain technology includes storing data in a block structure, using cryptography to ensure transmission and access security, etc., which can realize data consistent storage, anti-tampering, and a decentralized technical system. [0003] A smart contract is a computer protocol designed to disseminate, verify or enforce a contract in an informational manner, which can be represented as a computer program that runs accurately on the blockchain. User terminals can conduct transactions, share data, and establish trust by using smart contracts, and the characteristic...
