Abstract

The invention provides a decentralized lotting/queuing method and system based on a block chain and a smart contract. The method comprises the following steps: constructing a lotting/queuing smart contract original book and deploying the original book on a block chain network; initiating a lotting/queuing activity by referring to the smart contract original book through DAPP by an activity initiator; carrying out registration certification on a smart contract copy through the DAPP by an activity participant; carrying out activity participation application operation through the DAPP and submitting relevant application information by the activity participant; automatically performing lotting/queuing operation by the smart contract copy for the particular activity; sending, by a smart contract copy block chain account, a 'target currency' to an account of the activity participant to whom an acquisition priority of an 'activity subject matter' should be given; and claiming, by the activityparticipant who owns the 'target currency', the right to acquire the activity subject matter from the event initiator. The method and the system provided by the invention can solve the problems thatthe information is not open and transparent, the chance of fraud is more, and the system is easy to be breached by hackers and the like in the existing centralized lotting/queuing system.

Description

Technical field [0001] The present invention relates to the technical field of blockchain and smart contracts, in particular to a decentralized lottery / queuing method and system based on blockchain and smart contracts. Background technique [0002] At present, there are a large number of social behaviors in real life that use lottery / queuing as the means of execution. For example, the allocation of car license indicators, the determination of the purchase priority in the "seckill" promotion, the determination of the eligibility to purchase "anjufang", and so on. The characteristic of these activities is to allocate a limited subject matter among a relatively large number of applicants, and draw lots / queue the applicants according to certain rules to determine the applicants who obtain the subject matter. [0003] Usually, in these social activities, a centralized service platform will be established, and the event organizer will publish on this centralized platform the characteris...
