Abstract

Systems and methods for storing and managing blockchain transactions may include receiving a transaction request on a distributed ledger transaction machine that is part of a distributed ledger network including distributed ledger transaction machines, each storing an identical copy of a blockchain. The method may include extracting percentage allocations for each transaction in the transaction request as well as a set of identifying information indicating a charitable owner for at least one of the transactions. The method may further include recording a first transaction in a block on the distributed ledger transaction machine, which can be freely exchanged and transferred on the distributed ledger network and is unmarked, and a second transaction on the block on the distributed ledger transaction machine, including restricting the second transaction via a marking in the second transaction'"'"'s data where the marking enables a centralized machine to control access and use of the second transaction.

Claims

1. A method comprising:

receiving a transaction request on a first distributed ledger transaction machine of a plurality of distributed ledger transaction machines, which are part of a distributed ledger network, each storing an identical copy of a blockchain;

extracting percentage allocations for each transaction in the transaction request as well as a set of identifying information indicating an owner for at least one of the transactions;

recording a first transaction extracted from the transaction request in a block on the blockchain, on the first distributed ledger transaction machine according to a first percentage allocation from the extracted percentage allocations, where the first transaction can be freely exchanged and transferred on the distributed ledger network and is unmarked;

recording a second transaction on the block on the first distributed ledger transaction machine according to a second percentage allocation from the extracted percentage allocations, including restricting the second transaction via a marking in the second transaction'"'"'s data where the marking enables a centralized machine to control access and use of the second transaction, which is not controlled by the distributed ledger network; and

transmitting an identifier for the second transaction to the centralized machine for storage and management.

2. The method of claim 1, where the second transaction is added to a controlled ledger on the centralized machine.

3. The method of claim 2, where the identifier for the second transaction is a hash associated with the second transaction and is stored in the controlled ledger to identify the second transaction.

4. The method of claim 3, wherein the marking is a data field logged as part of the second transaction recording on the block and indicates to the distributed ledger network that the second transaction cannot be used.

5. The method of claim 1, where the total of the first and second percentage allocation is equal to one.

6. The method of claim 1, where the marking is a data field logged as part of the second transaction recording on the block.

7. The method of claim 1, where the set of identifying information includes the exact legal name of a charitable institution and associated tax identifier of the owner.

8. The method of claim 1, wherein the transmitted identifier is a hash of the second transaction and the set of identifying information includes at least one of the owner'"'"'s mailing address, website address, annual tax period, customer receipt number, a customer receipt number, an Automated Clearing House confirmation number, a donor identification, or identification of contribution amount.

9. A method comprising:

receiving a request on a centralized machine to release a marked transaction which is recorded on a distributed ledger network comprising distributed ledger transaction machines each storing an identical copy of a blockchain distributed ledger, wherein the centralized machine controls access and use of the markings;

identifying the marked transaction on a data structure local to the centralized machine, wherein the data structure is used for controlling the access and use of the markings;

updating the local data structure to indicate release of the marked transaction; and

transmitting a new transaction to the distributed ledger network for recording and adding to the blockchain distributed ledger as indication of the release.

10. The method of claim 9, wherein the local data structure is a centralized blockchain.

11. The method of claim 10, wherein the centralized blockchain stores the legal name and EIN for the owner of the marked transaction.

12. The method of claim 11, wherein the centralized blockchain indicates whether the transaction should be restricted or not.

13. The method of claim 12, wherein the marked transaction was created as a result of a split transaction where the marked transaction was a specified percentage to be allocated to a charity.

14. The method of claim 9, wherein the centralized blockchain has a first transaction recorded when the marked transaction is initially recorded on the distributed ledger network.

15. The method of claim 14, further comprising:

creating a second transaction indicating a release of the marked transaction which is linked by a hash of the first transaction.

16. The method of claim 15, further comprising:

updating the local data structure to record the second transaction, including the hash of the first transaction.

17. The method of claim 9, wherein the local data structure is a release list.

18. The method of claim 17, further comprising:

adding an entry to the release list when the marked transaction is initially recorded on the distributed ledger network where the entry is linked to the marked transaction via a hash of the marked transaction.

19. The method of claim 18, further comprising:

marking the entry as locked during the initial recording.

20. The method of claim 19, further comprising:

updating the local data structure by changing the marking for the entry to unlocked; and

the transmitted new transaction includes a hash identifier to the marked transaction.
