A block chain-based transaction processing method

Abstract

The invention discloses a block chain-based transaction processing method, which comprises the following steps that (1) a block chain node receives a transaction request and sends transaction information to a virtual machine; (2) the virtual machine executes the transaction and returns a result to the original block chain node; (3) the blockchain node puts the transaction and the result into a to-be-packaged queue, and packages a plurality of transactions executed within a set time interval; (4) the block chain node broadcasts the packaged transactions, sends the transactions to other block chain nodes and then puts the transactions into a reversible transaction queue; (5) after other block chain nodes receive the transaction, the verification consensus is carried out, and a consensus result is returned to the original block chain node; (6) the transaction is converted into an irreversible transaction by the original block chain node according to a transaction PBFT consensus mechanism,and the irreversible transaction is put into a non-transactional queue; and (7) the irreversible transaction is packaged into a block produced by the block chain node by the original block chain node. According to the invention, the transaction processing efficiency is greatly improved.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a transaction processing method based on block chains. Background technique [0002] At present, the blockchain technology makes the block irreversible after reaching a consensus on the block, and then the transaction on the block becomes irreversible to complete the transaction. However, there are some disadvantages: [0003] 1. The transaction must be irreversible, and after the block is irreversible, in the DPOS protocol, only one producer produces a block at a time point, that is to say, the transaction can only be executed on one node at the same time point, other nodes Can only be idle, resulting in a waste of resources. [0004] 2. In the DPOS protocol, the time required to reach a consensus on a block = the number of nodes * the time to produce a block, resulting in a longer transaction confirmation time. [0005] 3. An error in any transaction in the block will caus...

Problems solved by technology

[0003] 1. The transaction must be irreversible, and after the block is irreversible, in the DPOS protocol, only one producer produces a block at a time point, that is to say, the transaction can only be executed on one node at the same time point, other nodes Can only be idle, resulting in a waste of resources

[0004] 2. In the DPOS protocol, the time required to reach a consensus on a block = the number of nodes * the time to produce a block, resulting in a longer transaction confirmation time

[0005] 3. An error in any transaction in the block will cause the transaction on the entire block to be rolled back, resulting in a strong correlation between the transaction consensus on the same block

[0006] 4. Transactions on the blockchain will be broadcast immediately when they are sent to the chain, causing network congestion when the number is large
