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 generated that splits the match into two different transactions—one between the first identifier and an intermediary and the second between the intermediary and the second identifier. These are recorded to the blockchain via the further blockchain transactions.

Claims

1. A computer system operable with a distributed blockchain computer system that is configured to store a blockchain, the computer system comprising:

a transceiver configured to communicate with at least another computer system that communicates messages regarding matches between different data transaction requests;

a processing system that includes at least one hardware processor, the processing system configured to;

receive, via the transceiver, match data that includes data for a match between a first data transaction request that is associated with a first client identifier and a second data transaction request that is associated with a second identifier;

based on reception of the match data;

generate a first blockchain transaction that includes data for a first transaction from the first client identifier to an intermediary identifier that is associated with the intermediary account, wherein the data for the first transaction is based on at least one value that is included in the received match data, and

generate a second blockchain transaction that includes data for a second transaction from the intermediary identifier to the second client identifier, wherein the data for the second transaction is based on at least one value that is included in the received match data;

cause the first and second blockchain transactions to be incorporated into the blockchain of the distributed blockchain computer system; and

generate a blockchain transaction that includes a programmatic structure, the programmatic structure including a timer condition or time condition, which upon satisfaction thereof, is configured to trigger an additional action that is automatically performed.

2. The computer system of claim 1, 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.

3. The computer system of claim 2, 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.

4. The computer system of claim 2, 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.

5. The computer system of claim 1, 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.

6. The computer system of claim 5, 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.

7. The computer system of claim 1, 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.

8. The computer system of claim 7, 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.

9. The computer system of claim 1, 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.

10. A non-transitory computer readable storage medium storing instructions for use with a computer system that includes a transceiver and a storage system, the computer system configured to operate with a distributed blockchain computer system that includes a blockchain, the stored instructions comprising instructions that, when executed, cause the computer system to:

receive match data based on a match between a first data transaction request that is associated with a first client identifier and a second data transaction request that is associated with a second client identifier;

generate at least one blockchain transaction that includes data for a first transaction from the first client identifier to an intermediary identifier that is associated with an intermediary, wherein the data for the first transaction is based on at least one of the values included with the received match data, wherein the at least one blockchain transaction includes data for a second transaction that is from the intermediary identifier to the second client identifier, wherein the data for the second transaction is based on at least one of the values included with the received match data;

cause the at least one blockchain transaction to be incorporated into the distributed blockchain computer system; and

incorporate a programmatic structure into a blockchain transaction that is stored to the blockchain, the programmatic structure configured to be run upon satisfaction of a timer condition or time condition, which, upon satisfaction thereof, is set to automatically execute at least one further programmatic action.
