Embodiment 1

[0030] Such as figure 1 As shown, the blockchain-based supply chain service platform disclosed in this embodiment includes a blockchain system, a supply chain terminal, a query terminal, and a business system.

[0031] The blockchain system includes a blockchain BaaS module and a smart contract module.

[0032] The blockchain BaaS module is used to query, publish or verify the block data corresponding to the supply chain traceability contract; the smart contract module is used to establish the supply chain traceability contract and publish it on the chain through the blockchain BaaS module; the blockchain BaaS module adopts Existing BaaS platforms, such as those provided by companies such as Ali and Tencent.

[0033] The supply chain end includes the supply chain information collection module and the information on-chain module; the supply chain information collection module is used to collect commodity information and supply chain information and form traceability informatio...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is that in this embodiment, both the commodity information and the traceability request include commodity image data, and also include an image verification module, which is used to collect commodities according to the query end and each supply chain end. The image data judges whether there is an abnormality in the product, and if there is an abnormality, an abnormality reminder is sent to the corresponding query terminal.

[0040]The image verification module includes a feature recognition extraction module and a feature verification module. The feature recognition extraction module is used to extract the product features in the product image data according to the feature extraction rules. The feature recognition extraction module includes a feature extraction rule acquisition module. Product features and feature extraction rules, the feature extraction module is used to extract product features according to the fe...

Embodiment 3

[0043] The difference between this embodiment and Embodiment 2 is that in this embodiment, the feature checking module includes a neural network checking model, the neural network checking model adopts a BP neural network model, and the neural network checking model is used to Features and product features of the product image data uploaded by other links in the supply chain, whether the output product is abnormal.

Abstract

The invention relates to the technical field of block chains, in particular to a supply chain service platform based on a block chain, comprising: a block chain system comprising a block chain BaaS module and an intelligent contract module; a supply chain end comprising a supply chain information acquisition module and an information chaining module, wherein the supply chain information acquisition module is used for acquiring commodity information and supply chain information and forming tracing information, and the information chaining module is used for adding the tracing information into asupply chain tracing contract as a record of the supply chain tracing contract; a query module which is used for querying from the block chain BaaS module according to the tracing request and generating a query result; and a query end which is used for sending a tracing request to the tracing module and also used for receiving and displaying a query result of the tracing system. According to thesupply chain service platform based on the block chain, the circulation data of the product in the supply chain can be stored through the block chain technology, and the problems of low credibility and poor security in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of block chain, in particular to a supply chain service platform based on block chain. Background technique [0002] Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a non-tamperable and non-forgeable distributed ledger that is cryptographically guaranteed. Its most basic concept , is to use block chain data structure to verify and store data, use distributed node consensus algorithm to generate and update data, use cryptography to ensure the security of data transmission and access, and use smart contracts composed of automated script codes to program A brand-new distributed infrastructure and computing method for operating and operating data, with the characteristics of decentralization, immutable information, and privacy protection. [0003] Supply chain management is the entire process from production to customers, including packaging...
