Abstract

A system may provide hardware acceleration for blockchain-based record entry. Client circuitry may provide record entry information to node circuitry. The node circuitry may compile the record entry information into a record entry for submission to blockchain management circuitry (BMC). The BMC may access a consensus operating procedure. The BMC may apply the consensus operating procedure to the record entry to gain append permissions for a blockchain. After completing the consensus operating procedure, the BMC may append a block generated based on the record entry to the blockchain. Accordingly, the system may ensure that blocks added to the blockchain were generated in compliance with the consensus operating procedure.

First claim

What is claimed is:

1. A method comprising:
in a record entry hardware system:
receiving, at blockchain management circuitry (BMC), a record entry for a selected transaction from node circuitry;
obtaining a certificate configured to grant access to a portion of a blockchain, the obtaining a certificate responsive to an identity of the node circuitry;
determining that the record entry applies to the portion of the blockchain;
accessing, in memory within the BMC, a definition for a consensus operating procedure,
the consensus operating procedure responsive to the blockchain and the identity of the node circuitry;

determining a previous threshold maximum for the consensus operation procedure;
altering the previous threshold maximum to reflect a new threshold maximum;
responsive to altering the previous threshold maximum, applying the consensus operating procedure to generate a new accumulated value to cancel an effect of the selected transaction,
the new accumulated value generated by performing a processor-level operation using a previous accumulated value and the record entry as inputs,
the selected transaction determined to have occurred after the new threshold maximum was exceeded, but before the previous threshold maximum was exceeded, and
the previous accumulated value stored within a selected block of the blockchain; and

generating a new block for the blockchain,
the generating the new block responsive to:
the new accumulated value, and
a hash value generated using content of a previous block on the blockchain.

2. The method of claim 1 , where:
the consensus operating procedure comprises a smart contract; and
the definition comprises a term for the smart contract.

3. The method of claim 1 , where:
the record entry comprises a medical claim value;
the previous accumulated value comprises a health accum value generated based on pharmacy claim information; and
performing the processor-level operation comprises performing an add operation using the previous accumulated value and the medical claim value as inputs.

4. The method of claim 3 , where performing the add operation comprises calculating, across medical and pharmacy claims: an out-of-pocket contribution, a deductible contribution, or both.

5. The method of claim 1 ,
where applying the consensus operating procedure to generate a new accumulated value further comprises marking a previous transaction stored in the blockchain as erroneous; and
the method further comprises adjusting the previous accumulated value to cancel an effect of the previous transaction.

6. The method of claim 1 ,
where applying the consensus operating procedure to generate a new accumulated value further comprises correcting a transaction date for a previous transaction stored in the blockchain; and
the method further comprises changing the previous accumulated value over a period determined by the transaction date before and after correction.

7. The method of claim 1 , where the generating the new block further comprises generating the new block responsive to completion of the consensus operating procedure.

8. The method claim 1 , further comprising obtaining a validity indicator responsive to completion of the consensus operating procedure.

9. The method of claim 1 , where the selected block and the previous block comprise the same block.

10. A device comprising:
memory configured to store a blockchain;
communication interface circuitry configured to receive a record entry for a selected transaction from node circuitry; and
blockchain management circuitry (BMC) in data communication with the memory and communication interface circuitry, the BMC configured to:
responsive to an identity of the node circuitry, obtain a certificate configured to grant access to a portion of a blockchain;
determine that the record entry applies to the portion of the blockchain;
access a definition for a consensus operating procedure responsive to the blockchain and the identity of the node circuitry;
determine a previous threshold maximum for the consensus operation procedure;
alter the previous threshold maximum to reflect a new threshold maximum;
responsive to altering the previous threshold maximum, apply the consensus operating procedure to generate a new accumulated value by performing a processor-level operation using a previous accumulated value and the record entry as inputs to cancel an effect of the selected transaction,
the previous accumulated value stored within a selected block of the blockchain, and
the selected transaction determined to have occurred after the new threshold maximum was exceeded, but before the previous threshold maximum was exceeded; and

generate a new block for the blockchain responsive to the new accumulated value and a hash value generated using content of a previous block on the blockchain.

11. The device of claim 10 , where:
the record entry comprises a medical claim value;
the previous accumulated value comprises an accumulated value generated based on pharmacy claim information; and
the BMC is configured to perform the processor-level operation by performing an add operation using the previous accumulated value and the medical claim value as inputs.

12. The device of claim 11 , where the BMC is configured to perform the add operation by calculating, across medical and pharmacy claims: an out-of-pocket contribution, a deductible contribution, or both.

13. The device of claim 10 , where:
the BMC is further configured to apply the consensus operating procedure to generate a new accumulated value by marking a previous transaction stored in the blockchain as erroneous; and
the BMC is configured to perform another processor-level by adjusting the previous accumulated value to cancel an effect of the previous transaction.

14. The device of claim 10 , where:
the BMC is further configured to apply the consensus operating procedure to generate a new accumulated value by correcting a transaction date for a previous transaction stored in the blockchain; and
the BMC is configured to perform another processor-level operation by changing the previous accumulated value over a period determined by the transaction date before and after correction.

15. A system comprising:
input interface circuitry configured to accept input of record entry information;
a display configured to present a representation of specific data from a blockchain, the specific data comprising values from a transaction for a specific claim type;
client circuitry coupled to the input interface circuitry and the display, the client circuitry configured to:
receive the record entry information from the input interface circuitry, the record entry information relevant to a specific claim type;
receive the specific data; and
generate the representation of the specific data;

specific node circuitry in data communication with the client circuitry, the specific node circuitry configured to:
receive the record entry information from the client circuitry;
compile the record entry information into a record entry for the specific claim type;
generate a request for the specific data; and

blockchain management circuitry (BMC) in data communication with node circuitry, the BMC configured to:
responsive to the specific node circuitry being associated with the specific claim type
obtain a specific certificate configured to grant access to a specific portion of a blockchain adapted to store the specific claim type; and
