This invention proposes a blockchain consensus method based on device-independent quantum random number beacons. A blockchain sorting algorithm is used to rank the participating nodes. Each node sequentially requests a private device-independent quantum random number block from the beacon service network. The digital signature of the beacon is verified. Nodes that pass verification participate in the consensus process. According to an agreed-upon algorithm, the random number blocks allocated to each verified node are processed with a second hash value. Nodes whose results meet a threshold condition are selected as the chosen nodes to verify the authenticity and validity of the random number blocks of other nodes. If the verification passes, the consensus round is complete. The consensus mechanism based on device-independent random number beacons proposed in this invention has high security and fairness. Nodes can request private device-independent random number blocks through the beacon service network. The election process is low-power, more efficient, and easier for network expansion.
