Block chain dynamic DPoS consensus method based on reputation mechanism and DPBFT algorithm

The invention relates to a block chain dynamic DPoS consensus method based on a reputation mechanism and a DPBFT algorithm, and belongs to the technical field of block chains. The method comprises thefollowing steps: S1, initializing a whole network node reputation record; S2, counting the reputation weight votes and the number of support nodes of each node, selecting the nodes with the votes ranked at the top TN to form Pool, and selecting the nodes ranked at the top n from the Pool as representative nodes; S3, generating a random sequence through a shuffling algorithm by representative nodes, confirming a reason of a problem through a DPBFT algorithm, and taking processing measures until all the representative nodes of one sequence complete block production; and S4, generating a new block output sequence through a shuffling algorithm after a round of block production is completed until the next operation period or the number of candidate nodes is less than a threshold TNM. A reputation mechanism is introduced to reduce the influence of malicious nodes on the system in the DPOS voting process and the block production process, and the enthusiasm of nodes in the whole network to participate in the consensus process is improved.

Cloud computing system and method for running high-performance computation in same

The invention relates to a cloud computing system and a method for running high-performance computation in the same. The method comprises a step of creating a high-performance computation resource pool. The step of creating the high-performance computation resource pool specifically comprises: creating a scheduling system virtual machine in a computing node based on a high-performance computation operation demand by a cloud computing management system to run a high-performance computation scheduling system, creating computation virtual machines in a certain quantity of computing nodes, and returning information of the computation virtual machines to the high-performance computation scheduling system to form the high-performance computation resource pool. The created high-performance computation resource pool further can dynamically add and recover resources. According to the method, the high-performance computation resource pool is created in the cloud computing system; and by adopting a virtualization technology, the flexibility and elasticity brought by virtualization can be achieved in high-performance computation, and nearly no performance loss is caused. Therefore, the utilization rate of resources can be increased, the monopolization of a single business to the resources can be broken through, and the dynamicity of a whole computing service platform is realized.
