Abstract

The invention relates to the technical field of block chains, and provides a fast lot drawing / sorting method based on a block chain technology, comprising the following steps: S1, a lot drawing / sorting activity participant randomly selecting a lot drawing / sorting block from historical blocks of a block chain; S2, the activity sponsor selecting a block which is output only at the T2 moment in the future as an initial drawing / sorting block; establishing a lot drawing / sorting table, starting from an initial block, calculating an index value and a next block of which the index value is calculated by utilizing a random number in a lot drawing / sorting block head, and calculating a lot drawing / sorting number according to the index value of each block. The method is suitable for various situations with digital numbers as drawing / sorting results. Therefore, the possibility of drawing / sorting cheating is technically eliminated, all drawing / sorting results can be quickly determined only by acquiring the random number parameter in one newly-issued block, and the sorting method is simple and quick.
