Blockchain Node Selection for Regional Fairness

The patent applies local quality by differentiating node selection based on geographic region. Nodes prioritize selecting Inbound adjacent nodes from the same region, creating locally optimized data reception paths. This regional preference reduces transmission distance and latency for the majority of nodes while maintaining limited connectivity to other regions, thereby improving block data reception speed without completely sacrificing network diversity.

By prioritizing same-region nodes for Inbound adjacent node selection, the patent creates more uniform data reception conditions across the network. Nodes within the same geographic region experience similar transmission latencies, reducing the variation in block data reception times among miners. This local optimization ensures that all nodes have comparable opportunities to receive and process blocks, thereby maintaining mining fairness while preserving adequate reception reliability through sufficient regional node connectivity.

The patent implements a hierarchical node selection strategy where same-region nodes are prioritized for Inbound adjacent node roles, creating fast local data propagation paths. Non-regional nodes are not completely excluded but receive lower priority in selection, ensuring that the majority of data transmission occurs over short distances within regions. This approach maintains essential network connectivity for inter-region communication while ensuring that block transmission speed is optimized by the predominant same-region connectivity.
