Abstract

The invention discloses a chain network segmentation and recombination method and system for a large-scale Internet of Things scene. The method comprises the steps that consensus subjects firstly execute active recombination or segmentation based on a guide instruction, perform network detection, and select to execute a passive segmentation operation, a passive recombination operation or keep original network structures unchanged based on dynamic change conditions of a network; and finally, all the consensus subjects knot historical states in parallel, determine consensus algorithms for current consensus groups to which the consensus subjects belong, and perform consensus in parallel to finally complete a round of consensus. According to the invention, when network partition occurs, an Internet of Things man-machine cooperation system based on a block chain is ensured to continuously reach a consensus to generate blocks, and the blocks generated during the partition can be fused after a network is recovered, so that partition or fusion is timely and rapid, and data is ensured to be traceable and tamper-proof; and the invention not only supports a plurality of consensus algorithms, but also supports a block chain organizational structure in which different block chain structures coexist.

Description

technical field

[0001] The present invention relates to the field of Internet of Things and block chains, in particular to a chain network segmentation and reorganization method and system for large-scale Internet of Things scenarios. Background technique

[0002] Blockchain technology was first born in the article "Bitcoin: A Peer-to-Peer Electronic Cash Payment System" by Satoshi Nakamoto in 2008. This technology provides a new technical idea to solve the consistency problem of distributed systems. The core of this new technical idea is based on the consensus mechanism of the distributed system, that is, in the peer-to-peer network, nodes that lack trust (that is, devices with certain computing power and storage capacity) follow a preset mechanism (usually this The preset mechanism that makes the data finally reach a consensus is called a consensus algorithm) and finally reaches the consistency of the data. The user's payment behavior is completed through the transaction,...

Embodiment Construction

[0089] Such as figure 1 As shown, the chain network segmentation and reorganization method for large-scale Internet of Things scenarios in this embodiment includes:

[0090] 1) The consensus subject communicates with other consensus subjects in the Internet of Things to generate an initial consensus group;

[0091] 2) The consensus subject monitors whether the guidance reorganization instruction or the guidance segmentation instruction is received, and if the guidance reorganization instruction is received, then jump to step 3); if the guidance segmentation instruction is received, then jump to step 4); otherwise, jump to step 5 );

[0092] 3) All consensus subjects in the blockchain consensus system determine that the command controlled by the consensus group is a guide reorganization command, and perform reorganization operations on the consensus subjects involved in the guide reorganization command, and reorganize the consensus subjects involved in the guide reorganization...
