Reputation profile propagation on blockchain networks

1. A system comprising:

a memory; and

a processor in communication with the memory, the processor being configured to perform processes comprising:

initiating a non-fungible token on a blockchain network, wherein the non-fungible token is linked to an identity;

establishing a profile, linked to the identity, for the non-fungible token;

receiving reputation data related to the identity;

weighting the reputation data based on a trust of the reputation;

determining, based on the reputation data and one or more reputation rules, a reputation score,

wherein the one or more reputation rules evaluate a performance of a user linked to the profile,

wherein the reputation score includes a provenance of a scoring methodology,

wherein the scoring methodology includes weighting information based on a trust of an information source,

wherein the reputation score is based on a calculation of points based on a number of successful transactions and a number of failed transactions,

wherein the reputation score is based on client feedback from one or more reviews associated with the non-fungible token, and

wherein the reputation score is decreased for a failed transaction;

appending the non-fungible token with the reputation score as a non-fungible token metadata tag on the blockchain network;

invoking a reputation score validation smart contract with instructions to validate the reputation score;

checking to determine that the reputation score, appended as a part of the non-fungible token metadata tag, is valid; and

uploading, based on the checking, the non-fungible token and the non-fungible token metadata tag to an ID repository.

2. The system of claim 1 , the process further comprising:

creating an operation output that includes the non-fungible token metadata tag;

injecting the operation output into a block; and

recording the block to a blockchain ledger.

3. The system of claim 1 , wherein the receiving includes retrieving the reputation data from the ID repository, wherein the reputation data was appended to the ID repository by a second blockchain network.

4. The system of claim 1 , wherein the determining includes:

retrieving the one or more reputation rules from a reputation module engine, wherein the rules dictate how the reputation data is used to determine the reputation score.

5. A method comprising:

initiating, by a node, a non-fungible token on a blockchain network, wherein the non-fungible token is linked to an identity;

establishing, by the node, a profile, linked to the identity for the non-fungible token;

receiving, by the node, reputation data related to the identity;

weighting the reputation data based on a trust of the reputation;

determining, by the node based on the reputation data and one or more reputation rules, a reputation score,

wherein the one or more reputation rules evaluate a performance of a user linked to the profile,

wherein the reputation score includes a provenance of a scoring methodology,

wherein the scoring methodology includes weighting information based on a trust of an information source,

wherein the reputation score is based on a calculation of points based on a number of successful transactions and a number of failed transactions,

wherein the reputation score is based on client feedback from one or more reviews associated with the non-fungible token, and

wherein the reputation score is decreased for a failed transaction;

appending, by the node, the non-fungible token with the reputation score as a non-fungible token metadata tag on the blockchain network;

invoking a reputation score validation smart contract with instructions to validate the reputation score;

checking to determine that the reputation score, appended as a part of the non-fungible token metadata tag, is valid; and

uploading, by the node based on the checking, the non-fungible token and the non-fungible token metadata tag to an ID repository.

6. The method of claim 5 , further comprising:

creating an operation output that includes the non-fungible token metadata tag;

injecting the operation output into a block; and

recording the block to a blockchain ledger.

7. The method of claim 5 , wherein the receiving includes retrieving the reputation data from the ID repository, wherein the reputation data was appended to the ID repository by a second blockchain network.

8. The method of claim 5 , wherein the determining includes:

retrieving the one or more reputation rules from a reputation module engine, wherein the reputation rules dictate how the reputation data is used to determine the reputation score.

9. The method of claim 5 , wherein the reputation score is based on activity associated with the non-fungible token.

10. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processors to perform a method, the method comprising:

initiating an identity as a non-fungible token on a blockchain network;

establishing a profile, on the blockchain network for the identity as part of the non-fungible token;

receiving reputation data related to the identity;

weighting the reputation data based on a trust of the reputation;

determining, based on the reputation data and one or more reputation rules, a reputation score,

wherein the one or more reputation rules evaluate a performance of a user linked to the profile,

wherein the reputation score includes a provenance of a scoring methodology,

wherein the scoring methodology includes weighting information based on a trust of an information source,

wherein the reputation score is based on a calculation of points based on a number of successful transactions and a number of failed transactions,

wherein the reputation score is based on client feedback from one or more reviews associated with the non-fungible token, and

wherein the reputation score is decreased for a failed transaction;

appending the non-fungible token with the reputation score as a metadata tag;

invoking a reputation score validation smart contract with instructions to validate the reputation score;

checking to determine that the reputation score, appended as a part of the non-fungible token metadata tag, is valid; and

uploading, based on the checking, the non-fungible token and the metadata tag to an ID repository.

11. The computer program product of claim 10 , the method further comprising:

creating an operation output that includes the metadata tag;

injecting the operation output into a block; and

recording the block to a blockchain ledger.

12. The computer program product of claim 10 , wherein the receiving includes retrieving the reputation data from the ID repository, wherein the reputation data was appended to the ID repository by a second blockchain network.

13. The computer program product of claim 10 , wherein the determining includes:

retrieving the one or more reputation rules from a reputation module engine, wherein the reputation rules dictate how the reputation data is used to determine the reputation score.

14. The computer program product of claim 10 , wherein the reputation score is based on one or more reviews associated with the identity.
