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] Such as figure 1 As shown, the fragmentation method of the multi-domain layered IoT consorti...

The invention belongs to the technical field of block chain, and discloses a multi-domain layered Internet of Things alliance chain platform and its fragmentation method, and a computer; trusted institutions will assign it to different fragments according to the identity of the smart device, and the fragmentation Divided into main shards and general shards, the main shards and general shards are mapped one by one with the central domain and management domain of the platform; the Internet of Things smart devices in the shards are P2P connected to establish a network, and the identity of the most important node in the network Elected as the cluster head node; each IoT smart device broadcasts the generated transaction to the participants inside the shard, and the participants execute the improved PBFT consensus protocol; each shard broadcasts the generated shard block to the main shard Internal participants, participants execute the improved PBFT consensus protocol. The adoption of the present invention can almost linearly improve the block chain transaction consensus performance 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. ...
