Power measurement data tracing method based on Cloud DPoS

The invention provides a cloud data traceability block chain consensus algorithm ClodDPoS based on a DPoS (Data Point of Service). According to the consensus algorithm, cloud computing resources are quantified into rights and interests in the DPoS consensus algorithm, a biased timer similar to Raft consensus is opened for each node according to the size of the rights and interests, and voting results are dispersed; a one-person one-ticket voting method is combined, so that the selection probability of a high-quality cloud resource owner is ensured while the node election efficiency is improved; a feedback mechanism is introduced in a consensus process, so that a node election process is immediately restarted when more than 50% of unaccepted blocks of nodes are found in the consensus process, and the correctness of block generation is ensured. Compared with the prior art, the method has the advantages that the resource consumption of the BlockCloud can be reduced, and the consensus efficiency and the supportin
