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.

First claim

The invention claimed is:

1. A computer system comprising:
non-transitory storage configured to store data for a plurality of accounts that are associated with at least one cryptographic key, the plurality of accounts including an intermediary account;
at least one hardware processor configured to:
receive match data of 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;
based on reception of the match data:
generate a first blockchain transaction that includes data for a first transaction from the first identifier to an intermediary identifier that is associated with the intermediary account, wherein the data that is included in 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 identifier, wherein the data that is included in the second transaction is based on at least one value that is included in the received match data;

communicate the first and second blockchain transactions to a distributed blockchain computer system for incorporation into a blockchain that is maintained by the 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 at least one hardware processor is further configured to:
generate a third blockchain transaction that includes the match data of the match between the first data transaction request and the second data transaction request; and
communicate the third blockchain transaction to the distributed blockchain computer system to be incorporated into the blockchain.

3. The computer system of claim 2 , wherein the third blockchain transaction that includes the match data of 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 first and/or second blockchain transactions are dependent on the third blockchain transaction.

5. 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.

6. The computer system of claim 1 , wherein the programmatic structure is a smart contract that is embedded into blockchain transactions and is executed by at least one hardware processor of the blockchain computer system based on satisfaction of the timer condition or time condition.

7. The computer system of claim 1 , wherein the at least one hardware processor 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.

8. The computer system of claim 7 , 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.

9. 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 identifier that have been included in blockchain transactions for a given time period.

10. The computer system of claim 9 , wherein the additional action that is automatically performed includes automatically generating a further blockchain transaction that is from the first identifier to the intermediary identifier or from the intermediary identifier to the first 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.

11. 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.

12. A method for interacting with a blockchain, the method comprising:
receiving match data that includes 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;
generating, with at least one hardware processor, at least one blockchain transaction that includes:
first data for a first transaction from the first identifier to an intermediary identifier, wherein the first data for the first transaction is at least based on one or more values in the received match data, and
second data for a second transaction that is from the intermediary identifier to the second identifier, wherein the second data for the second transaction is at least based on one or more values in the received match data;

communicating, by using the at least one hardware processor, the at least one blockchain transaction to a blockchain computer system for incorporation into a blockchain that is maintained by the blockchain computer system; and
generating a programmatic structure and include the programmatic structure into at least one generated blockchain transaction, the programmatic structure configured to automatically execute to execute out at least one programmatic action upon expiration of a timer.

13. The method of claim 12 , wherein the at least one programmatic action includes:
calculating a sum total amount based on all transactions associated with the first identifier that have been included in blockchain transactions for a given time period, and
automatically generating a further blockchain transaction that is from the first identifier to the intermediary identifier or from the intermediary identifier to the first 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.

14. The method of claim 12 , wherein the programmatic structure is a smart contract that is embedded into the at least one generated blockchain transaction and is executed by the at least one hardware processor of the blockchain computer system based on expiration of the timer.

15. The method of claim 12 , wherein the match data is stored to the blockchain as part of the at least one blockchain transaction.

16. The method of claim 12 , further comprising:
signing, with a cryptographic key that is associated with an oracle account, an event that triggers expiration of the timer,
wherein the timer condition or time condition are triggerable if and only if an event that satisfies the condition has been signed with the cryptographic key of the oracle account.

17. The method of claim 12 , wherein the at least one programmatic action includes:
calculating a sum total amount based on all transactions associated with the first ide
