The invention discloses a lottery random number output method and equipment applying a blockchain. The lottery random number output method comprises the steps that: a lottery client initiates a transfer request on the blockchain, wherein the transfer request comprises an initiator address, a receiver address and a transfer amount, and the transfer request is used for lottery number output; the lottery client carries out hash operation on the transfer request to obtain a first hash value; the lottery client acquires a transfer number n in a block currently corresponding to the lottery client; the lottery client divides the transfer number n by the first hash value to obtain a corresponding first remainder m; the lottery client acquires an mth sum of transfer in a block currently corresponding to the lottery client, and carries out hash operation on the mth sum of transfer to obtain a second hash value; and the lottery client divides a preset integer by the second hash value to obtain acorresponding second remainder, wherein the second remainder is a current lottery output number, and the preset integer decides a number change interval of the lottery output number. The lottery random number output method and equipment ensures randomness, publicity, credibility and capacity of checking of the lottery number output 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...
