1. A method comprising: (6) (1)

in a record entry hardware system: determining, at blockchain management circuitry (BMC), a correction for a previous record entry stored within a blockchain, the correction comprising changing an original transaction date for the previous record entry to a corrected transaction date;

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

selecting the consensus operating procedure responsive to the blockchain, the consensus operating procedure detailing a rule for application to block content prior to appending blocks to the blockchain;

obtaining a previous accumulated value stored within a selected block of the blockchain and generated without the correction;

applying the consensus operating procedure to generate a corrected accumulated value from the previous accumulated value, where the applying comprises performing a processor-level operation using the correction and the previous record entry as inputs; and

generating a corrective indicator comprising: a reference to the previous accumulated value and the selected block, and

the corrected accumulated value; and

generating a hash value using content of a previous block in the blockchain;

after complying with the consensus operating procedure, generating a corrective block for the blockchain, the generating the corrective block responsive to the corrective indicator and the hash value generated using the content of the previous block in the blockchain;

designating a period of review between the original transaction date and the corrected transaction date;

marking, for review, a specific block storing a specific record entry with an affected transaction date during the period of review.

2. The method of claim 1, further comprising: (0) (2)

3. The method of claim 1, where generating the corrective block comprises correcting the previous record entry while maintaining storage of the previous accumulated value in the selected block. (0)

5. The method of claim 1, (0) (2)

7. The method of claim 1, further comprising applying the consensus operating procedure to define a new threshold maximum. (2) (0)

11. The method claim 1, where marking the specific block for review comprises adding a review indicator for the selected block to the corrective block. (0)

12. The method of claim 1, where marking the specific block for review comprises adding a review indicator for the selected block to metadata for the blockchain. (0)

13. A device comprising: (3) (2)

memory configured to store a blockchain;

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

access an identifier of a consensus operating procedure responsive to the blockchain, the consensus operating procedure detailing a rule for application to block content prior to appending blocks to the blockchain;

determine a correction for a previous record entry, the correction comprising changing an original transaction date for the previous record entry to a corrected transaction date;

obtain a previous accumulated value stored within a selected block of the blockchain and generated without the correction;

apply the consensus operating procedure to generate a corrected accumulated value from a previous accumulated value by performing a processor-level operation using the correction and the previous record entry as inputs; and

generate a corrective indicator comprising: a reference to the previous accumulated value and the selected block, and

the corrected accumulated value;

generate a hash value using content of a previous block on the blockchain;

after complying with the consensus operating procedure, generate a corrective block for the blockchain responsive to the corrective indicator and the hash value;

designate a period of review between the original transaction date and corrected transaction date; and

mark, for review, a specific block storing a specific record entry with an affected transaction date during the period of review.

14. The device of claim 13, where the BMC is further configured to apply the consensus operating procedure to generate a corrected accumulated value by defining a new threshold maximum. (2) (0)

18. The device claim 13, where the BMC is configured to mark the specific block for review by adding a review indicator for the specific block to the corrective block. (0)

19. The device of claim 13, where the BMC is configured to mark the specific block for review by adding a review indicator for the specific block to metadata for the blockchain. (0)

17. (canceled) (0)

20. A system comprising: (4) (5)

a display configured to present a representation of specific data from a blockchain, the specific data comprising values from a previous transaction;

input interface circuitry configured to accept input of an alteration to the specific data;

client circuitry coupled to the input interface circuitry and the display, the client circuitry configured to: receive the alteration to the specific data from the input interface circuitry, the alteration comprising changing an original transaction date for the previous transaction to a corrected transaction date;

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 alteration to the specific data from the client circuitry,

compile the alteration to the specific data into a correction for a previous record entry for the previous transaction,

generate a request for the specific data, and

after receiving the specific data, forwarding the specific data to the client circuitry; and

blockchain management circuitry (BMC) in data communication with node circuitry, the BMC configured to: receive the correction for the previous record entry from the node circuitry,

access a definition for a consensus operating procedure, the consensus operating procedure detailing a rule for application to block content prior to appending blocks to the blockchain;

apply the consensus operating procedure to generate a corrected accumulated value by performing a processor-level operation using a previous accumulated value and the previous record entry as inputs, the previous accumulated value stored within a specific block of the blockchain;

access the blockchain;

generate a corrective indicator comprising: a reference to the previous accumulated value and the specific block; and

the corrected accumulated value;

after complying with the consensus operating procedure, generate a corrective block for the blockchain responsive to the corrective indicator and a hash value generated using content of a previous block on the blockchain;

receive the request for the specific data;

access the specific portion of the blockchain to obtain the specific data;

send the specific data to the node circuitry;

designate a period of review between the original transaction date and corrected transaction date; and

mark, for review, a selected block storing a selected record entry with an affected transaction date during the period of review.
