摘要： Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for blockchain-based service processing. One of the methods includes receiving a service processing request by a first service processing platform from a first user. The first service processing platform is one of a plurality of service processing platforms that access a blockchain network, and service data of the first user is shared between the plurality of service processing platforms over the blockchain network. In response to a determination that the service processing request involves a second service processing platform of the plurality of service processing platforms, it is determined whether the service processing request is permitted to be executed. In response to determining that the service processing request is permitted to be executed, the service processing request is executed over the blockchain network.

摘要： Embodiments of the present specification disclose methods, apparatuses, and devices for transferring data assets based on a blockchain. One method includes: obtaining usage demand information of a data requestor for using original data, wherein the usage demand information indicates a demand of the data requestor for performing computations based on the original data; sending a usage authorization request for the original data to a data owner of the original data based on a decentralized identifier (DID) corresponding to the original data; receiving confirmation information of the usage authorization request from the data owner; processing the original data based on the usage demand information to obtain a processing result; transmitting the processing result to the data requestor; and generating a verifiable claim (VC) for recording usage information of the original data.

摘要： Disclosed herein are systems, methods, and media for processing and updating risk assessment information of a user. One of the methods here comprise: obtaining risk assessment information and digital identity of the user; creating a first verifiable claim based on the digital identity and the risk assessment information by using a first blockchain, revoking a second verifiable claim of original risk assessment information corresponding to the digital identity by using the first blockchain; uploading the first verifiable claim to a second blockchain; obtaining a storage credential of the first verifiable claim in the second blockchain, wherein the second blockchain is connected to a service processing platform; generating a risk assessment card corresponding to the user based on the storage credential and the first verifiable claim; and allowing the service processing platform to obtain the risk assessment information of the user from the second blockchain by using the risk assessment card.
