Systems and methods for managing digital identities

1. A computer-implemented method comprising acts of:

receiving a request to validate at least one statement about a user;

identifying, from the request, a reference to a distributed ledger, the reference comprising an identifier for the distributed ledger and an identifier for a transaction recorded on the distributed ledger;

identifying, based at least in part on the identifier for the distributed ledger, at least one node of a network of nodes managing the distributed ledger;

identifying an identity service provider that verified the at least one statement about the user;

determining whether the identity service provider is to be trusted; and

communicating with the at least one node to validate the at least one statement about the user only if:

the identity service provider is to be trusted; and

the at least one statement about the user is electronically signed by the identity service provider.

2. The method of claim 1 , wherein the act of identifying the at least one node comprises performing a lookup in a distributed hash table for the identifier for the distributed ledger.

3. The method of claim 2 , wherein the distributed hash table is managed by the network of nodes managing the distributed ledger.

4. The method of claim 1 , wherein the reference to the distributed ledger further comprises an identifier for a field in the transaction recorded on the distributed ledger.

5. The method of claim 1 , wherein the reference comprises a Uniform Resource Identifier (URI).

6. The method of claim 1 , further comprising acts of:

determining whether the distributed ledger is to be trusted; and

validating the at least one statement about the user only if the distributed ledger is to be trusted.

7. The method of claim 1 , wherein the distributed ledger comprises a first distributed ledger, the at least one node comprises at least one first node, and the network of nodes comprises a first network of nodes, and wherein:

the acts of receiving the request, identifying the reference, identifying the at least one node, and communicating with the at least one node are performed by at least one second node of a second network managing a second distributed ledger different from the first distributed ledger.

8. A system comprising:

at least one computer processor;

at least one non-transitory computer-readable medium having encoded thereon instructions which, when executed, cause the at least one computer processor to:

receive a request to validate at least one statement about a user;

identify, from the request, a reference to a distributed ledger, the reference comprising an identifier for the distributed ledger and an identifier for a transaction recorded on the distributed ledger;

identify, based at least in part on the identifier for the distributed ledger, at least one node of a network of nodes managing the distributed ledger;

identify an identity service provider that verified the at least one statement about the user;

determine whether the identity service provider is to be trusted; and

communicate with the at least one node to validate the at least one statement about the user only if:

the identity service provider is to be trusted; and

the at least one statement about the user is electronically signed by the identity service provider.

9. The system of claim 8 , wherein the at least one computer processor is programmed to identify the at least one node at least in part by performing a lookup in a distributed hash table for the identifier for the distributed ledger.

10. The system of claim 9 , wherein the distributed hash table is managed by the network of nodes managing the distributed ledger.

11. The system of claim 8 , wherein the reference to the distributed ledger further comprises an identifier for a field in the transaction recorded on the distributed ledger.

12. The system of claim 8 , wherein the reference comprises a Uniform Resource Identifier (URI).

13. The system of claim 8 , wherein the at least one computer processor is further programmed to:

determine whether the distributed ledger is to be trusted; and

validate the at least one statement about the user only if the distributed ledger is to be trusted.

14. The system of claim 8 , wherein the distributed ledger comprises a first distributed ledger, the at least one node comprises at least one first node, and the network of nodes comprises a first network of nodes, and wherein:

the at least one computer processor is on at least one second node of a second network managing a second distributed ledger different from the first distributed ledger.

15. At least one non-transitory computer-readable medium having encoded thereon instructions which, when executed, cause at least one computer processor to perform acts of:

receiving a request to validate at least one statement about a user;

identifying, from the request, a reference to a distributed ledger, the reference comprising an identifier for the distributed ledger and an identifier for a transaction recorded on the distributed ledger;

identifying, based at least in part on the identifier for the distributed ledger, at least one node of a network of nodes managing the distributed ledger;

identifying an identity service provider that verified the at least one statement about the user;

determining whether the identity service provider is to be trusted; and

communicating with the at least one node to validate the at least one statement about the user only if:

the identity service provider is to be trusted; and

the at least one statement about the user is electronically signed by the identity service provider.

16. The at least one computer-readable medium of claim 15 , wherein the act of identifying the at least one node comprises performing a lookup in a distributed hash table for the identifier for the distributed ledger.

17. The at least one computer-readable medium of claim 16 , wherein the distributed hash table is managed by the network of nodes managing the distributed ledger.

18. The at least one computer-readable medium of claim 15 , wherein the reference to the distributed ledger further comprises an identifier for a field in the transaction recorded on the distributed ledger.

19. The at least one computer-readable medium of claim 15 , wherein the reference comprises a Uniform Resource Identifier (URI).

20. The at least one computer-readable medium of claim 15 , wherein the method further comprises acts of:

determining whether the distributed ledger is to be trusted; and

validating the at least one statement about the user only if the distributed ledger is to be trusted.

21. The at least one computer-readable medium of claim 15 , wherein the distributed ledge comprises a first distributed ledger, the at least one node comprises at least one first node, and the network of nodes comprises a first network of nodes, and wherein:

the acts of receiving the request, identifying the reference, identifying the at least one node, and communicating with the at least one node are performed by at least one second node of a second network managing a second distributed ledger different from the first distributed ledger.
