Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] At present, the consensus throughput optimization technology of blockchain transactions is difficult to transplant to the multi-domain IoT alliance chain platform, which brings great performance pressure to the platform. The adoption of the present invention can almost linearly improve the block chain transaction consensus performance when facing massive transaction requests.

[0047] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0048] like figure 1 As shown, the fragmentation method of the multi-domain layered IoT consortium c...

Abstract

The invention belongs to the technical field of blockchains, and discloses a multi-domain hierarchical Internet of Things alliance chain platform and a fragmentation method thereof and a computer. A trusted organization allocates smart devices to different fragments according to identities of the smart devices, wherein the fragments are divided into main fragments and general fragments, and the main fragments and the general fragments are in a one-to-one mapping relationship with a central domain and a management domain of the platform; Internet of Things smart devices in the fragments establish a network through a P2P connection, and a node with the most important identity in the network is elected as a cluster header node; each Internet of Things smart device broadcasts the generated transaction to participants inside the fragments, and the participants implement the improved PBFT consensus protocol; and each fragment broadcasts the generated fragment block to the participants insidethe main fragments, and the participants implement the improved PBFT consensus protocol. By adopting the scheme of the invention, the blockchain transaction consensus performance can be improved almost linearly when facing massive transaction requests.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a multi-domain hierarchical Internet of Things alliance chain platform, a fragmentation method thereof, and a computer. Background technique [0002] The Internet of Things is a highly integrated and comprehensive application of the new generation of information technology, which is of great significance to the new round of industrial transformation and the green, intelligent and sustainable development of the economy and society. At present, the Internet of Things is entering a new stage of cross-border integration. In this stage, the data generated by different Internet of Things systems and management domains are integrated to form a more powerful industrial industry. Therefore, a dedicated, large-scale cross-domain contribution platform is needed. Emerging blockchain technology is considered as a technology with great potential for building such a platform. ...
