Embodiment Construction

[0034] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described The embodiments are only some of the embodiments in this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of this specification.

[0035] A current improvement method is: when the Leader node packs a block, it does not immediately execute the transaction in the block, but first implements a consensus on the block, and the consensus node executes the transaction after the block reaches a consensus. The block generates a new state; the Leader node at the next height will carry the new state ...

Abstract

The embodiment of the invention discloses a block chain consensus and execution parallel processing method and device and electronic equipment, and the method comprises the steps: carrying out the batch packaging of transactions, and carrying out the consensus of a transaction set obtained through packaging; after the consensus is reached, adding the sequenced transaction set to a preset buffer queue; sequentially executing transactions in each transaction set in the preset buffer queue; and after all transactions in any transaction set are executed, returning an execution result of the executed transaction set as a latest state. Therefore, in the mode, when one block is processed, parallel processing of transaction consensus and execution and parallel processing of transaction consensus and execution of adjacent blocks can be achieved, and it is guaranteed that in the whole consensus process, transaction consensus and execution are executed all the time, and the situation of parallelprocessing exists. Therefore, the consensus efficiency is improved.

Description

technical field [0001] This description relates to the technical field of computer software, in particular to a parallel processing method, device and electronic equipment for block chain consensus and execution. Background technique [0002] In blockchain technology, consensus can include at least two layers of semantics: 1. Complete transaction sequencing; 2. Reach consensus on the latest state. For blockchains that adopt the account model, transactions only contain events, and the state is generated after the transaction is executed. In order to achieve consensus on the latest state, a common method is: the consensus node executes all transactions in the block before packaging the block, and saves the calculated latest state in the block header of the block to be packaged. After the block containing the latest state reaches consensus, the transactions in the block are sequenced, and the latest state also completes the consensus. Any other consensus node can replay the t...
