Abstract

A computer system that interfaces with a blockchain is provided. The computer system receives match data for a match between a first data transaction request that is associated with a first identifier and a second data transaction request that is associated with a second identifier. A first blockchain transaction is generated based on the match data and stored to a blockchain. At least one further blockchain transaction is generates that splits the match into two different transactions—one between the first identifier and an intermediary and the second between the intermediary. These are recorded to the blockchain via the further blockchain transactions.

3. The computer system of claim 2, wherein the processing system is further configured to:

generate a third blockchain transaction that includes the match data for the match between the first data transaction request and the second data transaction request; and

cause the third blockchain transaction to be incorporated into the blockchain.

4. The computer system of claim 3, wherein the third blockchain transaction that includes the match data for the match between the first data transaction request and the second data transaction request is incorporated into the blockchain prior to the incorporation of the first and second blockchain transactions.

5. The computer system of claim 3, wherein the third blockchain transaction is structured to be from an identifier that is associated with a computer system that matches data transaction requests to another identifier that is associated with the computer system that received the match data.

6. The computer system of claim 2, wherein the processing system is further configured to:

sign, with a cryptographic key that is associated with a trusted oracle account, an event that is to trigger the timer condition or time condition of the programmatic structure.

7. The computer system of claim 6, wherein the timer condition or time condition is triggerable if and only if an event that satisfies the condition has been signed by the cryptographic key that is associated with the trusted oracle account.

8. The computer system of claim 2, wherein the programmatic structure includes instructions for:

calculating a sum total amount based on all transactions associated with the first client identifier that have been included in blockchain transactions for a given time period.

9. The computer system of claim 8, wherein the additional action that is automatically performed includes:

automatically generating a further blockchain transaction that is from the first client identifier to the intermediary identifier or from the intermediary identifier to the first client identifier, wherein data included in the further blockchain transaction is based on the calculated sum total amount, wherein the further blockchain transaction is subsequently incorporated into the blockchain.

10. The computer system of claim 2, wherein the additional action that is automatically performed includes generation of at least one new blockchain transaction that is subsequently incorporated into the blockchain, the at least one new blockchain transaction including data that is based on the data for the first transaction included in the first blockchain transaction.

11.
