The invention discloses a lottery random number-generating method and device applying blockchains. The lottery random number-generating method comprises the steps that a lottery client side initates atransfer request on the blockchains, and the transfer request includes an initator address, a receiver address and the transfer amount; the transfer request is used for lottery number generating; thelottery client side conducts Hash operation on the transfer request, thus a first Hash value is obtained, and the total block output number n of a current round of block output node is obtained; thelottery client side divides the first Hash value by the total block output number n, a corresponding first remainder m is obtained, the m block in the current round of total blocks is obtained, the m block is subjected to block Hash operation, and a second Hash value is obtained; the lottery client side divides the second Hash value by a preset integer, and thus a corresponding second remainder is obtained; the second remainder is the current generated lottery number; and the preset integer determines the numerical value change interval of the generated lottery number. It is ensured that the lottery number generating process is random, open, credible and retrievable.
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...
