S1623, user is obtained using the Headquarters of the General Staff and number of logical card redemption lottery share；
S1624, by numerical value to be processed to Headquarters of the General Staff and number remainder, to obtain intermediate value；
S1625, intermediate data is added one, to obtain prize-winning number.
Prize-winning number=(the 8 conversion decimal system after last transaction hash value) % commodity Headquarters of the General Staff and number+1；It gets the winning number in a bond
Number is that system calculates automatically, and when the draw times of particular commodity terminate, system will record institute after its last transaction cochain
In the block height of block, while 8 are taken after the hash value of the block height, 10 binary digits is converted into, based on the commodity
Headquarters of the General Staff and number carry out remainder, and obtained numerical value is prize-winning number plus 1, since the hash value of block chain is random number, nothing
Method human intervention ensure that the randomness and fairness of prize-winning number.
S170, prize-winning account and non-prize-winning account are filtered out according to prize-winning number.
Prize-winning number only one, therefore the corresponding account of the prize-winning number be prize-winning account, other are non-prize-winning account
Family.
