Example Embodiment
[0020]Such asfigure 1 As shown, for the present embodiment, the present embodiment relates to a node tissue structure of a block chain, wherein: node tissue as a participant's basic unit, including: 1 communication node and four consensus nodes, where there is only 1 in the same time A consensus node generates a master node.
[0021]The election, specifically, in each node tissue, each primary node will re-elect the primary node after stopping the service or participating in the N times consensus service. Among them, N can be preset by the number of nodes tissue in the node. If the primary node service expires, the primary node actively initiates voting; if the primary node service is unexpected, the sequencing node is voted to the other nodes within the node organization. At the same time, each node has its own address (private key), and members in the node organization will jointly maintain all the node addresses in this node organization. At the time of the election, each node calcu...
