Method and device for processing transactions in block chain

Abstract

The invention relates to the field of financial technology. The invention discloses a method and a device for processing transactions in a block chain. The method comprises the following steps: a transaction node receiving a to-be-processed transaction sent by the client, wherein the to-be-processed transaction comprises a first random number randomly generated by the client for the to-be-processed transaction, the transaction node carrying out first verification on the to-be-processed transaction, and after it is determined that the to-be-processed transaction passes the first verification, recording the first random number in a random number record and putting the to-be-processed transaction into a transaction pool. According to the technical scheme, the transaction node transaction processing efficiency is effectively improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of financial technology (Fintech), and in particular to a method and device for transaction processing in a blockchain (BlockChain). Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field. The traditional financial industry is gradually transforming into financial technology, and blockchain transmission technology is no exception. However, due to the security and real-time requirements of the financial and payment industries , but also higher requirements for technology. [0003] Blockchain is a chain composed of a series of blocks. Each block records the data of this block and the hash value of the previous block. All blocks form a chain successively in this way. The cryptography technology and decentralization idea on which the blockchain is based make the historical information on the chain impossible to be tamp...

Problems solved by technology

[0004] When the client sends the transaction to the blockchain, due to reasons such as the network, the client may send the same transaction multiple times. In order to prevent the same transaction from being processed multiple times, the existing technology uses a strict incremental sequence to achieve transaction prevention. Specifically, each account corresponds to a sequence, and this sequence starts counting from zero. Every time the client where the account is located sends a transaction, the sequence value is incremented by one, and the transaction node processes the same transaction in ascending order according to the sequence value of the transaction sent by the client. For account transactions, if the sequence value of the transaction received by the node is much greater than the sequence value of the transaction processed by the current node, the received transaction will be placed in the transaction pool until the transaction of the sequence value is processed. For this transaction, the efficiency of transaction nodes processing transactions in this way is low, and the client needs to generate strictly incremental sequence values, which has high requirements for the client
