The invention discloses a lottery random numbering method and equipment using a block chain, including: a lottery client initiates a transfer request on the block chain, and the transfer request includes: the address of the initiator, the address of the receiver, and the transfer amount; The request is used as a lottery number; the lottery client performs a hash operation on the transfer request to obtain the first hash value; the lottery client obtains the number n of transfers in the current corresponding block; Divide the Greek value by the number of transfers n to get the corresponding first remainder m; the lottery client obtains the mth transfer in the current corresponding block, and performs a hash operation on the mth transfer to get the second Hash value; the lottery client divides the second hash value by the preset integer to obtain the corresponding second remainder; the second remainder is the number of lottery numbers issued this time; the preset integer determines the numerical change of the number of lottery numbers interval. The invention guarantees the randomness, openness, credibility and checkability of the lottery ticket numbering process.
Description
technical field [0001] The present invention relates to the technical field of combination of block chain and lottery numbers, and more specifically, to a random lottery numbering method and equipment using block chain. Background technique [0002] In lottery markets around the world, lottery numbers can provide mechanical lottery numbers or random number generators to draw lottery tickets. Mechanical lottery lottery requires manpower and mechanical devices. Both the working conditions of the mechanical devices and manpower may affect the randomness of lottery numbers. However, the random number generator, whose awarding process is not transparent, may generate a specific ticket number based on statistical results, and cannot avoid the possibility of data being tampered with by insiders or hackers, and there are problems of non-disclosure and untrustworthiness. [0003] Blockchain is a new application model of computer technologies such as distributed data storage, point-t...
