The invention discloses a lottery random lottery 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: an address of an initiator, an address of a recipient, and a transfer amount; The transfer request is used as a lottery number; the lottery client performs a hash operation on the transfer request to obtain the first hash value, and obtains the total number of blocks n of the current round of block generation nodes; the lottery client calculates the first hash value Divide by the total number of blocks n to get the corresponding first remainder m, and get the mth block in the total blocks of the current round, and perform block hash operation on the mth block to get the first Two hash values; 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 value of the number of lottery numbers range of change. 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, relates to a random lottery numbering method using block chain and its equipment. 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 stor...
