Abstract
Disclosed is a public random number generation method based on a blockchain, including: selecting a node group G containing N trusted nodes; determining a first time point tand a second time point trespectively for generating an m-th/n-th block, wherein the former is earlier, and the m-th block is fixed and cannot be tampered at t; at the first time point t, enabling each of the N trusted nodes to separately generate a sub-random number ras a component forming a random number X, wherein j=1, 2, . . . , N, on which delayed encryption is performed, with corresponding results placed in the m-th block; and at the second time point t, decrypting the delayed encryption results to obtain decrypted data of them all that are all of sub-random number r, on which operation is performed to obtain the random number X as a final available public random number.
