Trunk-and-branch blockchain ledger architecture for validation of claims

A system, comprising:

• one or more processors;
• and
• memory storing executable instructions that, as a result of execution by the one or more processors, cause the system to:
• create a trunk blockchain ledger, comprising:
• a first unique identifier usable to access the trunk blockchain ledger;
• one or more signature rules;
• and
• one or more public keys;
• create, a first branch blockchain ledger, comprising:
• the first unique identifier;
• and
• a second unique identifier usable to access the first branch blockchain ledger;
• record, on the first branch blockchain ledger, at least a first blockchain transaction, wherein the first blockchain transaction comprises a first claim that is digitally signed using a private key corresponding to a public key of the one or more public keys;
• provide the first claim to a trusted entity;
• receive, from the trusted entity, a first endorsement pointer that references the first claim, wherein the first endorsement pointer comprises:
• a first hash of the first claim;
• and
• a reference to a first endorsement that is located on a second blockchain ledger that is controlled by the trusted entity;
• and
• record, on the first branch blockchain ledger, the first endorsement pointer.

A non-transitory computer-readable storage medium storing executable instructions that, as a result of being executed by one or more processors of a computer system, cause the computer system to at least:

• create a trunk blockchain ledger, comprising:
• a first unique identifier usable to access the trunk blockchain ledger;
• one or more signature rules;
• and
• one or more public keys;
• create, a first branch blockchain ledger, comprising:
• the first unique identifier;
• and
• a second unique identifier usable to access the first branch blockchain ledger;
• record, on the first branch blockchain ledger, at least a first blockchain transaction, wherein the first blockchain transaction comprises a first claim that is digitally signed using a private key corresponding to a public key of the one or more public keys;
• provide the first claim to a trusted entity;
• receive, from the trusted entity, a first endorsement pointer that references the first claim, wherein the first endorsement pointer comprises:
• a first hash of the first claim;
• and
• a reference to a first endorsement that is located on a second blockchain ledger that is controlled by the trusted entity;
• and
• record, on the first branch blockchain ledger, the first endorsement pointer.
