Abstract

A node associated with an organization may receive a storage identifier for new credit data associated with an individual. A distributed ledger and distributed data sources may be used to share the new credit data with a network of nodes. The node may update a smart contract with the storage identifier for the new credit data. The node may receive, from a particular device associated with the organization, a request for the new credit data. The node may obtain the storage identifier for the new credit data from the smart contract. The node may obtain the new credit data by using the storage identifier to search the distributed data sources. The node may provide the new credit data to the particular device. The node may perform actions to obtain additional new credit data from the distributed data sources or provide the additional new credit data to the distributed data sources.

First claim

What is claimed is:

1. A method, comprising:
receiving, by a first node, new credit data associated with an individual that has credit with a first organization,
wherein a second node is associated with a second organization is permitted to access the new credit data, and
wherein the new credit data has been provided to a set of distributed data sources by the second node;

updating, by the first node, a smart contract associated with the individual to include information associated with the new credit data; and
performing, by the first node, one or more actions associated with obtaining additional new credit data from the set of distributed data sources or providing the additional new credit data to the set of distributed data sources.

2. The method of claim 1 , further comprising:
receiving, from a device associated with the first organization, a request for the new credit data;
obtaining, by the first node, the information associated with the new credit data from the smart contract,
wherein the new credit data is obtained using a storage identifier to search the set of distributed data sources; and

providing, by the first node, the new credit data to the device associated with the first organization.

3. The method of claim 2 , wherein updating the smart contract comprises:
updating the smart contract with the storage identifier.

4. The method of claim 1 , further comprising:
obtaining the new credit data by using a storage identifier to search the set of distributed data sources; and
broadcasting the storage identifier for the new credit data to cause the second node to provide the storage identifier for the new credit data to a copy of the smart contract that is accessible to the second node.

5. The method of claim 1 , further comprising:
obtaining a storage identifier for the new credit data from the smart contract to cause the smart contract to provide digital currency associated with the first organization to an account associated with the second organization.

6. The method of claim 1 , further comprising:
generating, after receiving the new credit data, a storage identifier for the new credit data by using a content addressing technique to generate a cryptographic hash value identifying a storage location at which the new credit data is to be stored within the set of distributed data sources.

7. The method of claim 1 , wherein the smart contract includes one or more of:
data identifying a group of organizations that are permitted to access the new credit data,
a set of storage identifiers identifying a set of storage locations associated with historical credit data of the individual,
a first function associated with adding the new credit data to the set of distributed data sources,
a second function associated with obtaining the new credit data from the set of distributed data sources, or
third function associated with providing incentives to the group of organizations to use a network of nodes to interact with the smart contract to execute the first function and the second function,
the group of organizations including the first organization and the second organization, and
the network of nodes including the first node and the second node.

8. A first node, comprising:
one or more memories; and
one or more processors, communicatively connected to the one or more memories, to:
receive new credit data associated with an individual that has credit with a first organization,
wherein a second node is associated with a second organization is permitted to access the new credit data, and
wherein the new credit data has been provided to a set of distributed data sources by the second node;

update a smart contract associated with the individual to include information associated with the new credit data; and
perform an action associated with a copy of the new credit data and the set of distributed data sources.

9. The first node of claim 8 , wherein the one or more processors are further to:
broadcast a storage identifier to permit the second node to provide digital currency associated with the second organization to an account associated with the first organization.

10. The first node of claim 8 , wherein the one or more processors are further to:
receive, from a device associated with the first organization, a request for the new credit data;
obtain the information associated with the new credit data from the smart contract;
obtain the new credit data by using a storage identifier to search the set of distributed data sources; and
provide the new credit data to the device associated with the first organization.

11. The first node of claim 10 , wherein the one or more processors, when updating the smart contract, are to:
update the smart contract with the storage identifier.

12. The first node of claim 8 , wherein the one or more processors are further to:
obtain the new credit data by using a storage identifier to search the set of distributed data sources; and
broadcast the storage identifier for the new credit data to cause the second node to provide the storage identifier for the new credit data to a copy of the smart contract that is accessible to the second node.

13. The first node of claim 8 , wherein the one or more processors are further to:
obtain a storage identifier for the new credit data from the smart contract to cause the smart contract to provide digital currency associated with the first organization to an account associated with the second organization.

14. The first node of claim 8 , wherein the smart contract is used exclusively for the individual and includes a function associated with obtaining the new credit data from the set of distributed data sources; and
Wherein the function requires that a particular amount of digital currency be provided to obtain the new credit data.

15. A non-transitory computer-readable medium storing instructions, the instructions comprising:
one or more instructions that, when executed by one or more processors, cause the one or more processors of a first node to:
receive new credit data associated with an individual that has credit with a first organization,
wherein a second node is associated with a second organization is permitted to access the new credit data, and
wherein the new credit data has been provided to a set of distributed data sources by the second node;

provide information associated with the new credit data to a smart contract associated with the individual; and
perform an action associated with additional new credit data and the set of distributed data sources.

16. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, when executed by the one or more processors, further cause the one or more processors to:
store the smart contract as a block within a blockchain.

17. The non-transitory computer-readable medium of claim 15 , wherein the first organization includes one of:
a financial institution,
a lending institution, or
an organization with data that may be useful for determining a credit score.

18. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, when executed by the one or more processors, further cause the one or more processors to:
obtain the new credit data by using a storage identifier to search the set of distributed data sources; and
broadcast the storage identifier for the new credit data to cause the second node to provide the storage identifier for the new credit data to a copy of the smart contract th
