Technical Field

The present disclosure relates to the field of computer software technologies, and in particular, to a block output method and apparatus in a block chain consensus algorithm.

Background

At present, consensus protocols are considered as the core content of blockchain technology. The consensus protocol plays a crucial role no matter the design of transaction processing capacity, expansibility influence or incentive model of the blockchain platform.

Consensus protocols can be simply divided into: the two major protocols, the Proof of Work (PoW) consensus protocol and the Byzantine Fault Tolerance (BFT) consensus protocol, have been generated since the birth of bitcoin. The block-out process in the consensus mechanism of the BFT consensus protocol generally includes the following three stages:

1. the consensus node proposes a block and broadcasts the block to the whole network consensus;

2. the agreement is achieved, and the transaction in the proposal block is executed in series;

3. and storing the content of the proposal block, the transaction, the execution result and the transaction result into a database.

In the existing block output scheme, transaction execution and various storage operations in the above stages are executed serially, the storage operation can be executed only after the transaction execution operation is finished, and the next stage can be entered after one stage is finished, so that the block output speed is limited, the block output time is long, and the consensus efficiency is influenced.
