Limited commodity coupon information evidence storage method and system on blockchain

Abstract

The invention discloses a limited commodity coupon information evidence storage method and system on a blockchain, and belongs to the technical field of blockchain information. The method specificallycomprises the following steps: a blockchain node receives data information of limited commodity coupons issued by a merchant, wherein the data information comprises brands, discount coupon contents,serial numbers, discount coupon valid time, prices and the total number of pieces of limited commodity discount coupons; and the blockchain node performs consensus verification on the data informationand then stores the data information in a blockchain. According to the invention, consensus evidence storage is carried out on the data information of the limited commodity coupons uploaded by the merchant, and consensus evidence storage is carried out on the online or offline historical transaction information of the limited commodity coupons, so that consumers can identify real and credible information of the limited commodity coupons on the blockchain. The consumer can determine whether the limited commodity coupon actually sold by the merchant is consistent with the information declared by the merchant according to the information stored in the block chain, so that the consumer is prevented from being cheated, and the consumption experience of the consumer is ensured.
