Abstract

A method includes populating a template database with templates associated with template identifiers (IDs) identifying the templates. The method also includes generating a data model that references a template within the template database, where the data model includes a template ID referencing the template in the template database, and where the template includes a parameter field. The data model further includes a template parameter to apply to the parameter field and a digital signature for at least the template ID and the template parameter. The method also includes deploying the data model within a distributed ledger.

First claim

What is claimed is:

1. A method comprising:
populating a template database with templates associated with template identifiers (IDs) identifying the templates;
generating a data model that references a template within the template database, the data model comprising:
a template ID referencing the template in the template database,

wherein the template comprises a parameter field;
a template parameter to apply to the parameter field; and
a digital signature for at least the template ID and the template parameter; and

deploying the data model within a distributed ledger.

2. The method of claim 1 , wherein the template database comprises a second distributed ledger.

3. The method of claim 1 , wherein the templates are stored in an immutable format within the template database.

4. The method of claim 1 , wherein the data model is generated in a JSON (JavaScript Object Notation) file format.

5. The method of claim 1 , wherein the data model further comprises an attachment ID, the attachment ID referencing an encrypted document stored in a distributed storage network (DSN).

6. A system comprising:
a memory component; and
a processing device coupled to the memory component, the processing device to perform operations comprising:
generating a data model that references the template, wherein the template being referenced is stored within a template database, the template comprising a parameter field that is editable, the data model comprising:
a template identifier (ID) that identifies the template within the template database; and
a template parameter for applying to the parameter field;

receiving a digital signature for at least the template ID and the template parameter;
updating the data model with the digital signature; and
deploying the updated data model within a distributed ledger.

7. The system of claim 6 , wherein the template database comprises a second distributed ledger.

8. The system of claim 6 , wherein the templates are stored in an immutable format within the template database.

9. The system of claim 6 , wherein the data model is generated in a JSON (JavaScript Object Notation) file format.

10. The system of claim 6 , wherein the data model further comprises an attachment ID, the attachment ID referencing an encrypted document stored in a distributed storage network (DSN).

11. The system of claim 6 , wherein the digital signature comprises an aggregated signature that is representative of a plurality of signatures.

12. The system of claim 6 , wherein the template ID comprises a cryptographically secure string.

13. One or more non-transitory computer-readable medium storing executable instructions, which when executed by a processing device, cause the processing device to perform operations comprising:
identifying a template identifier (ID) referencing a template in a template database, wherein the template database comprises templates associated with template IDs identifying the templates;
identifying a template parameter for applying to a parameter field of the template;
obtaining a digital signature for at least the template ID and the template parameter;
generating a data model comprising:
the template ID;
the template parameter for applying to the parameter field; and
the digital signature; and

deploying the data model within a distributed ledger.

14. The medium of claim 13 , wherein the template database comprises a second distributed ledger.

15. The medium of claim 13 , wherein the templates are stored in an immutable format within the template database.

16. The medium of claim 13 , wherein the data model is generated in a JSON (JavaScript Object Notation) file format.

17. The medium of claim 13 , wherein the data model further comprises an attachment ID, the attachment ID referencing an encrypted document stored in a distributed storage network (DSN).

18. The medium of claim 13 , wherein the digital signature comprises an aggregated signature that is representative of a plurality of signatures.

19. The medium of claim 13 , wherein the template ID comprises a cryptographically secure string.
