Abstract

The invention relates to a block chain update method and a block chain update system. The method comprises the steps as follows: a central node receives a request message sent by a client; the centralnode broadcasts the request message to each node in a first node group where the central node is located, and each node in the first node group performs consensus processing on the request message; when each node in the first node group reaches a consensus for the request message, each node in a second node group and the node in the first node group perform data synchronization on the request message; when each node in the second node group completes data synchronization on the request message, a block chain is updated according to the request message. According to the block chain update method and the block chain update system provided by the invention, all nodes of the block chain are divided into two parts, the problems that there are excessive nodes and Byzantium fault-tolerance is not applicable are avoided, the quantity of all nodes can be accommodated by the network is improved, and the network fault-tolerant capability and expansibility are enhanced.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain update method and a block chain update system. Background technique [0002] The core problem of the normal work of a distributed system is to ensure that all nodes in the cluster have exactly the same data and can reach a consensus on a certain proposal. Traditional distributed systems face the following two problems: [0003] 1. The number of nodes increases or decreases, which may be due to node failure and downtime [0004] 2. The communication between nodes is disturbed or the terminal, there is a difference in operating speed or there is a delay in the blockchain network, etc. [0005] In reality, delays in the blockchain network are inevitable. A trade-off is made between strong consistency and availability. At present, mainstream distributed systems finally choose consistency. Multiple nodes are allowed to conflict, as long as the nodes can communica...
