Trustworthy data exchange using distributed databases

A computer-implemented method for a trustworthy data exchange, comprising:

• receiving, by a client device from a query device, a query, wherein the query comprises a question;
• identifying, by the client device, particular information related to the query;
• retrieving, by the client device, the particular information related to the query from one or more data repositories storing data verified by a trusted authority, wherein the one or more data repositories are part of a distributed database comprising an immutable data store that maintains a verifiable history of changes to information stored in the distributed database;
• determining, by the client device, based on the particular information related to the query, an answer to the query;
• and
• providing, by the client device, the answer to the query device, wherein the answer indicates that the answer is based upon information certified by the trusted authority.

A system for a trustworthy data exchange, comprising:

• one or more processors;
• and
• a memory comprising instructions that, when executed by the one or more processors, cause the system to:
• receive, from a device, a query, wherein the query comprises a question;
• identify particular information related to the query;
• retrieve the particular information related to the query from one or more data repositories storing data verified by a trusted authority, wherein the one or more data repositories are part of a distributed database comprising an immutable data store that maintains a verifiable history of changes to information stored in the distributed database;
• determine, based on the particular information related to the query, an answer to the query;
• and
• provide the answer to the device, wherein the answer indicates that the answer is based upon information certified by the trusted authority.
