Embodiment Construction

[0033] The present invention is further described below through specific examples, so that readers can have a more detailed understanding of the working logic and design features of the present invention.

[0034] Suppose there are 2 blind box companies, company A and company B, 2 consumers and 1 regulatory department. The specific process is as follows.

[0035] (1) Blockchain network initialization.

[0036] The regulatory department takes the lead in building a blockchain network and registers as the CA central node and supervisory node in the network.

[0037] Write a smart contract and deploy it to the network. The functions provided by the contract include but are not limited to:

[0038] Function Sell(ProductInfopf,Timetime,intindex,int cash)

[0039] / / sell function. The parameter pf contains the information of this batch of products, such as: the numbers of all blind boxes, the hash value of the numbers of rare blind boxes, and blind box promotional materials. ...

Abstract

The invention belongs to the technical field of blockchain, and specifically relates to a blockchain-based blind box sales platform. The blind box sales platform of the present invention has a four-layer structure: application layer, contract layer, consensus layer and data storage layer; among them, merchants encrypt and input the commodity information of the sales batch, the ratio of rare commodities and the corresponding serial number to the block chain In the smart contract, the random sale is carried out by the smart contract; the customer completes the purchase of the blind box by calling the smart contract, and obtains the corresponding number after the purchase is successful, and the merchant delivers the goods according to the customer number. After the batch of goods is sold, the smart contract will automatically compare the feedback ratio with the ratio provided by the merchant, and then package the batch of sales results into blocks and upload them to the chain. Compared with the existing platform, the present invention is more credible and fair, and all commodities sold are traceable on the block chain, which is convenient for supervision by relevant regulatory authorities.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to a blind box selling platform. Background technique [0002] At present, there are three sales models for blind boxes on the market, as follows: [0003] (1) For sale in store. This sales model belongs to the traditional sales model. Customers go directly to the corresponding store to buy the product and exchange it at the store. However, because it is sold in kind, there have been many salespersons who have received benefits to provide customers with internal information and customers to manually load the product or knead the product violently to guess. events in the blind box; [0004] (2) Vending machines for sale. Although this sales model solves the problem of eliminating store sales, since the vending machine is arranged by the merchant itself, in extreme cases, there may not be a single rare item inside the vending machine; [0005] (3) Official website s...
