Hardware blockchain consensus operating procedure enforcement

1. A method including:

in a record entry hardware system:

determining, at blockchain management circuitry (BMC), that a previous record entry stored within a blockchain is erroneous;

after determining that the previous record entry is erroneous, determining, at the BMC, a correction for the previous record entry;

accessing, in memory within the BMC, an identifier of a particular consensus operating procedure;

selecting the particular consensus operating procedure from among multiple consensus operating procedures defined within the memory,

the particular consensus operating procedure selected responsive to the blockchain;

obtaining a previous accumulated value stored within a previous valid block of the blockchain and generated without the correction, the previous valid block being valid based on consistence between the previous valid block and a previous hash stored within the blockchain;

applying the particular consensus operating procedure to generate a corrected accumulated value from the previous accumulated value, where the applying includes:

marking the previous record entry as erroneous; and

performing a processor-level operation using the correction and the previous record entry as inputs; and

after the previous valid block is validly stored within the blockchain and after applying the particular consensus operating procedure, generating a corrective indicator including:

a reference to the previous accumulated value and the previous valid block, and the corrected accumulated value;

generating a preceding hash value using content of an immediately preceding block in the blockchain;

generating a corrective block for the blockchain,

the generating a corrective block for the blockchain responsive to the corrective indicator and the preceding hash value; and

appending the corrective block to the blockchain,

the previous valid block remaining valid after the corrective block is appended.

2. A device including:

a memory configured to store a blockchain; and

blockchain management circuitry (BMC) in data communication with the memory, the BMC configured to:

access the blockchain in the memory;

determine that a previous record entry stored within the blockchain is erroneous;

after determining that the previous record entry is erroneous, determine a correction for the previous record entry;

access an identifier of a particular consensus operating procedure;

select the particular consensus operating procedure from among multiple consensus operating procedures defined within the memory,

the particular consensus operating procedure selected responsive to the blockchain,

obtain a previous accumulated value stored within a previous valid block of the blockchain and generated without the correction, the previous valid block being valid based on consistence between the previous valid block and a previous hash stored within the blockchain;

apply the particular consensus operating procedure to generate a corrected accumulated value from the previous accumulated value, where the BMC is configured to apply the consensus operating procedure by:

marking the previous record entry as erroneous; and

performing a processor-level operation using the correction and the previous record entry as inputs;

after the previous valid block is validly stored within the blockchain and after applying the particular consensus operating procedure, generate a corrective indicator including:

a reference to the previous accumulated value and the previous valid block; and the corrected accumulated value;

generate a preceding hash value using content of a immediately preceding block in the blockchain;

generate a corrective block for the blockchain,

the corrective block generated responsive to the corrective indicator and the preceding hash value; and

append the corrective block to the blockchain, the previous valid block remaining valid after the corrective block is appended.

3. A product including:

machine-readable media other than a transitory signal; and

instructions stored on the machine-readable media, the instructions configured to, when executed, cause blockchain management circuitry (BMC) to:

determine that a previous record entry stored within a blockchain is erroneous;

after determining that the previous record entry is erroneous, determine a correction for the previous record entry;

access an identifier of a particular consensus operating procedure;

select the particular consensus operating procedure from among multiple consensus operating procedures defined within a memory;

the consensus operating procedure selected responsive to the blockchain;

obtain a previous accumulated value stored within a previous valid block of the blockchain and generated without the correction, the previous valid block being valid based on consistence between the previous valid block and a previous hash stored within the blockchain;

apply the particular consensus operating procedure to generate a corrected accumulated value from the previous accumulated value, where the BMC is configured to apply the consensus operating procedure by:

marking the previous record entry as erroneous; and

performing a processor-level operation using the correction and the previous record entry as inputs; and

after the previous valid block is validly stored within the blockchain and after applying the particular consensus operating procedure, generate a corrective indicator including:

a reference to the previous accumulated value and the previous valid block, and the corrected accumulated value;

generate a preceding hash value using content of a immediately preceding block in the blockchain;

generate a corrective block for the blockchain,

the corrective block generated responsive to the corrective indicator and the preceding hash value; and

append the corrective block to the blockchain, the previous valid block remaining valid after the corrective block is appended.

4. The product of claim 3 , where the previous record entry is erroneous due to an incorrect timestamp.

5. The product of claim 3 , where the previous record entry is erroneous due to an improper classification of a service associated with the previous record entry.

6. The product of claim 3 , where previous record entry is erroneous due to a update to the consensus operating procedure causing a range of affected dates.

7. The product of claim 3 , where the instructions are further configured to cause the BMC receive a message identifying that the previous record entry is erroneous.

8. The product of claim 7 , where the instructions are configured to cause the BMC to receive the message from node circuitry authorized by the BMC.

9. The product of claim 8 , where the instructions are configured cause the BMC to authorize the node circuitry responsive to a credential provided by the node circuitry.

10. The product of claim 3 , where the previous record entry is erroneous due to latency in transaction reporting.

11. The method of claim 1 , where the previous record entry is erroneous due to an incorrect timestamp.

12. The method of claim 1 , where the previous record entry is erroneous due to an improper classification of a service associated with the previous record entry.

13. The method of claim 1 , where previous record entry is erroneous due to a update to the consensus operating procedure causing a range of affected dates.

14. The method of claim 1 , further comprising receiving a message identifying that the previous record entry is erroneous.

15. The method of claim 14 , where the receiving the message comprises receiving the message from node circuitry authorized by the BMC.

16. The method of claim 15 , further comprising authorizing, via the BMC, the node circuitry responsive to a credential provided by the node circuitry.
