Abstract

The disclosed technology includes a distributed ledger system that can include one or more transaction blocks that are associated with one or more transaction records of an account corresponding to the primary account number. The system may allocate a first type block in a first distributed ledger, and the first type block may be utilized to identify a classification type associated with the first primary account number. The system may receive, at the first node, a first transaction indication associated with the first primary account number. Responsive to receiving the first transaction indication, the system may bind a first transaction block to the first distributed ledger. Transaction blocks may be configured for selective control and/or selective replicated to other nodes of the system. In response to an end-of-cycle indication, the first transaction block may be locked to prevent further modification.

First claim

We claim:

1. A distributed ledger processing system, comprising:
a processor;
a memory storing computer readable instructions that when executed by the processor cause the processor to perform the steps of:
receiving a transaction indication associated with a primary account number (PAN), the transaction indication including transaction data and block-level permission data;
extracting the transaction data and the block-level permission data from the transaction indication;
appending, to a PAN-specific chain, a block comprising the extracted transaction data;
setting the block as modifiable by an API according to the extracted block-level permission data;
subsequent to setting the block as modifiable, receiving transaction data for the PAN;
based on the setting of the block as modifiable, modifying, with the API, the modifiable block by updating the extracted transaction data in the block with the received transaction data;
retrieving, from a database in communication with the processor, an end-of-billing-cycle indication; and
responsive to the end-of-billing-cycle indication:
adding a block to the PAN-specific chain;
receiving transaction data subsequent to the adding of the block, wherein the transaction comprises the PAN; and

writing the transaction data comprising the PAN to the added block.

2. The distributed ledger processing system of claim 1 , wherein the computer readable instructions, when executed by the processor, further cause the processor to perform the step of transmitting the modifiable block to at least a second networked processor of the distributed ledger.

3. The distributed ledger processing system of claim 1 , wherein the computer readable instructions, when executed by the processor, further cause the processor to perform the step of storing, in a local memory of the first node, the extracted block-level permission data.

4. The distributed ledger processing system of claim 1 , wherein the end-of-billing-cycle indication comprises a predetermined date.

5. The distributed ledger processing system of claim 1 , wherein the transaction indication further comprises one or more of: transaction amounts, date stamp, time stamp, vendor information, read permissions, write permissions, edit permissions, and delete permissions.

6. The distributed ledger processing system of claim 1 , wherein the computer readable instructions, when executed by the processor, further cause the processor to perform the steps of:
establishing the PAN-specific chain; and
allocating a type block identifying a classification type associated with the PAN; wherein the type block designates one or more special events associated with the PAN, wherein the one or more special events comprise one or more of: a test, a marketing event, a rate offer, check access, and a cash advance.

7. The distributed ledger processing system of claim 1 , wherein the PAN is one or more of: an issuer of a credit card, a cardholder entity status, an account number associated with the credit card, and an authentication code.

8. The distributed ledger processing system of claim 1 , wherein the computer readable instructions, when executed by the processor, further cause the processor to perform the step of allocating, responsive to the end-of-billing-cycle indication, at least a second block of the PAN-specific chain for one or more of: a future end-of-billing-cycle, a dispute, an account change, and a fraud event.

9. The distributed ledger processing system of claim 1 , wherein the computer readable instructions, when executed by the processor, further cause the processor to perform the step of validating the block.
