Abstract: A product anti-counterfeiting method based on a material signature blockchain. The method includes chaining of signature information and product information, QR code generation, query of on-chain information, and offline inspection. Also disclosed is an anti-counterfeiting system of the product anti-counterfeiting method based on a material signature blockchain. The system includes a product material signature module, a module of chaining signature information and product information, a module of generating a QR code, a module of querying on-chain information, and an offline inspecting module. The present invention proposes a product anti-counterfeiting method and a system based on a material signature blockchain according to the above content, which uses the material signature technology to solve the problem of the authenticity of the off-chain product.

Abstract: Disclosed is a blockchain-enabled edge computing method for production scheduling. The method includes modeling a smart contract between a device and a manufacturing unit, and using the smart contract to perform production scheduling on the device inside the manufacturing unit; one of the manufacturing units includes multiple devices; mounting each device on the blockchain operating node, the MES issues production instructions to the nodes of each manufacturing unit, at the same time, the nodes acquire production data of the device through multiple data sources of the device, the operating state data and process parameter data of each device are acquired in real time, and the data is directly chained from the device level; according to the production instructions and device parameters obtained by the manufacturing unit, using edge computing to dynamically adjust the device load, efficiency, and utilization.

Abstract: Disclosed is a smart contract and an automatic bargaining method for secure multi-party computation and a device embodies same. A first public key and a first private key are generated based on a homomorphic encryption algorithm in the smart contract, the first public key is sent to a demander and a supplier so that the demander and the supplier encrypt the purchase price and the sale price through the first public key, respectively; after receiving a second public key and an encrypted purchase price sent by the demander and a third public key and an encrypted sale price sent by the supplier, the encrypted sale price and the encrypted purchase price that meet the preset transaction conditions are decrypted.
