Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for blockchain-based notification are provided. One of the methods includes: obtaining, from a computing device associated with a first decentralized identifier (DID), a query about event data; in response to the obtained query, searching a data store to obtain one or more notifications for event data associated with a second DID, wherein a DID document associated with the second DID comprises the first DID, and wherein the DID document is stored in a blockchain; and providing the one or more notifications for the computing device associated with the first DID.
Claims20
A computer-implemented method for blockchain-based notification, comprising:
- obtaining, from a computing device associated with a first decentralized identifier (DID), a query about event data;
- in response to the obtained query, searching a data store to obtain one or more notifications for event data associated with a second DID, wherein a DID document associated with the second DID comprises the first DID, and wherein the DID document is stored in a blockchain;
- and
- providing the one or more notifications for the computing device associated with the first DID.
A system for blockchain-based notification, the system comprising one or more processors and one or more non-transitory computer-readable memories coupled to the one or more processors and configured with instructions executable by the one or more processors to cause the system to perform operations comprising:
- obtaining, from a computing device associated with a first decentralized identifier (DID), a query about event data;
- in response to the obtained query, searching a data store to obtain one or more notifications for event data associated with a second DID, wherein a DID document associated with the second DID comprises the first DID, and wherein the DID document is stored in a blockchain;
- and
- providing the one or more notifications for the computing device associated with the first DID.
A non-transitory computer-readable storage medium for blockchain-based notification, the storage medium configured with instructions executable by one or more processors to cause the one or more processors to perform operations comprising:
- obtaining, from a computing device associated with a first decentralized identifier (DID), a query about event data;
- in response to the obtained query, searching a data store to obtain one or more notifications for event data associated with a second DID, wherein a DID document associated with the second DID comprises the first DID, and wherein the DID document is stored in a blockchain;
- and
- providing the one or more notifications for the computing device associated with the first DID.
