Entity certification management

1. A certificate issuer node in a blockchain network, the certificate issuer node comprising:

a processor that when executing one or more instructions stored in a memory is configured to:

receive, from an asset producer node of the blockchain network via a blockchain of the blockchain network, a request to execute a certification process to verify an origin and an integrity of an asset from the asset producer node;

generate, by the certification process, a digital certificate linked to the request and assigned to the asset producer node;

link the digital certificate to an authority of the certificate issuer node;

link the digital certificate to a plurality of credentials documents issued by another certificate issuer node based on location data associated with the asset and identification data of the certificate issuer node; and

sign the digital certificate to ensure origin and integrity of the asset.

2. The certificate issuer node of claim 1 , wherein the request comprises a digital signature of the asset producer node.

3. The certificate issuer node of claim 2 ,

verify integrity of the request based on the digital signature of the asset producer node.

4. The certificate issuer node of claim 1 , wherein the processor is further configured to:

record a signed digital certificate on a ledger of the blockchain.

5. The certificate issuer node of claim 1 , wherein the processor is further configured to:

provide access permission to an asset producer node certification record to other participants on the blockchain.

6. A method, comprising:

receiving, by a certificate issuer node of a blockchain network and from an asset producer node of the blockchain network, a request to execute a certification process to verify an origin and an integrity of an asset from the asset producer node;

generating, by the certificate issuer node executing the certification process, a digital certificate linked to the request and assigned to the asset producer node;

linking, by the certificate issuer node, the digital certificate to an authority of the certificate issuer node;

linking, by the certificate issuer node, the digital certificate to a plurality of credentials documents issued by another certificate issuer node based on location data associated with the asset and identification data of the certificate issuer node; and

signing, by the certificate issuer node, the digital certificate to ensure origin and integrity of the asset.

7. The method of claim 6 , wherein the request comprises a digital signature of the asset producer node.

8. The method of claim 7 , comprising:

verifying integrity of the request based on the digital signature of the asset producer node.

9. The method of claim 6 , further comprising:

recording a signed digital certificate on a ledger of the blockchain.

10. The method of claim 6 , further comprising:

providing access permission to an asset producer node certification record to other participants on the blockchain.

11. A non-transitory computer readable medium comprising one or more instructions that when executed by a processor of a certificate issuer node in a blockchain network cause the processor to perform:

receiving, from an asset producer node of the blockchain network, a request to execute a certification process to verify an origin and an integrity of an asset from the asset producer node;

generating, by the certification process, a digital certificate linked to the request and assigned to the asset producer node;

linking the digital certificate to an authority of the certificate issuer node;

linking, by the certificate issuer node, the digital certificate to a plurality of credentials documents issued by another certificate issuer node based on location data associated with the asset and identification data of the certificate issuer node; and

signing the digital certificate to ensure origin and integrity of the asset.

12. The non-transitory computer readable medium of claim 11 , wherein the request comprises a digital signature of the asset producer node.

13. The non-transitory computer readable medium of claim 12 , wherein the one or more instructions further cause the processor to perform:

verifying integrity of the asset certification request based on the digital signature of the asset producer node.

14. The non-transitory computer readable medium of claim 11 , wherein the one or more instructions further cause the processor to perform:

recording a signed digital certificate on a ledger of the blockchain.
