Resumen de: US2020159577A1

A node in a blockchain network receives service data generated in a specified time period, where the service data comprises label information used to represent a processing priority of the service data. The node determines, when a new block is generated, a throughput that corresponds to the label information based on a predetermined mapping relationship between label information and a throughput. The node obtains service data that satisfies the throughput and that comprises the label information from a data processing set based on the throughput, where the service data is stored in the data processing set. The service data is stored in the new block.

Resumen de: US2020162244A1

The present specification discloses a blockchain-based method and apparatus for encrypting and decrypting product information. A producer may encrypt production information based on a unique secret code of a product. When a distributor is present, the distributor may unidirectionally generate a distribution key according to the unique secret code, and the distributor may further generate a distribution information encryption key according to the distribution key, encrypt distribution information, and generate a next distribution key according to the distribution information encryption key. That is, the product information is encrypted by unidirectionally generating keys successively along the chain. The production information is encrypted and stored based on characteristics that the unique secret code of the product is accessible only to the producer and a buyer and the blockchain is tamper-proof and forgery-proof, so that the production information is highly confidential.
