Abstract

A computer-implemented method comprising receiving a request to execute a transaction transferring transaction data from a first account to a second account associated with a second computing device in communication with a distributed ledger, the request comprising an identification of the first account and the second account; identifying a third account associated with a third computing device in communication with the distributed ledger; retrieving first account data for the first account and third account data for the third account from the distributed ledger; comparing a first value from the first account data and a third value from the third account data to a threshold; determining the transaction satisfies a transaction policy; and generating a record in the distributed ledger indicating the transaction transferring the transaction data from the first account to the second account in response to the determination that the transaction satisfies the transaction policy.

First claim

What we claim is:

1 . A method comprising:
receiving, by a first computing device in communication with a distributed ledger from a computing device associated with a first account, a request to execute a transaction transferring transaction data from the first account to a second account associated with a second computing device in communication with the distributed ledger, the request comprising an identification of the first account and the second account; identifying, by the first computing device, a third account associated with a third computing device in communication with the distributed ledger in response to a hierarchical model indicating for the third account to be involved in a transaction between the first account and the second account; retrieving, by the first computing device, first account data for the first account and third account data for the third account from the distributed ledger; comparing, by the first computing device, a first value from the first account data and a third value from the third account data to a threshold; determining, by the first computing device, the transaction satisfies a transaction policy in response to the first value and the second value exceeding the threshold; and generating, by the first computing device, a record in the distributed ledger indicating the transaction transferring the transaction data from the first account to the second account in response to the determination that the transaction satisfies the transaction policy.

2 . The method of claim 1 , wherein generating the record in the distributed ledger comprises storing, by the first computing device, identifications of the first account, the second account, and the third account in the record.

3 . The method of claim 1 , wherein the hierarchical model is stored in the distributed ledger.

4 . The method of claim 1 , wherein retrieving the first account data from the distributed ledger comprises retrieving, by the first computing device, a first account balance of the first account and wherein retrieving the third account data from the distributed ledger comprises retrieving, by the first computing device, a third account balance of the third account.

5 . The method of claim 4 , wherein retrieving the first account data comprises aggregating, by the first computing device, balances from any transactions that were recorded on the distributed ledger that involved the first account.

6 . The method of claim 4 , wherein retrieving the first account data comprises retrieving, by the first computing device, the first account data from a single record in the distributed ledger.

7 . The method of claim 6 , wherein the distributed ledger comprises a blockchain, and wherein retrieving the first account data from a single record in the distributed ledger comprises retrieving, by the first computing device, the first account data from a single block instance that was previously appended to the blockchain.

8 . The method of claim 6 , wherein generating the record in the distributed ledger comprises:
updating, by the first computing device, the first account data based on the transaction; and generating, by the first computing device, the record in the distributed ledger to include the updated first account data.

9 . The method of claim 1 , wherein generating the record in the distributed ledger comprises transmitting, by the first computing device, one or more messages to one or more computing devices in communication with the distributed ledger, the one or more messages containing a plurality of predetermined transaction attributes for the transaction.

10 . The method of claim 1 , wherein generating the record in the distributed ledger comprises generating, by the first computing device, the record without communicating with the second computing device.

11 . A system comprising:
a first computing device comprising a network interface in communication with a computing device associated with a first account, a memory device storing an instance of a distributed ledger, and a processor configured to:
receive, via the network interface, a request to execute a transaction transferring transaction data from the first account to a second account associated with a second computing device in communication with the distributed ledger, the request comprising an identification of the first account and the second account;
identify a third account associated with a third computing device in communication with the distributed ledger in response to a hierarchical model indicating for the third account to be involved in transactions between the first account and the second account;
retrieve first account data for the first account and third account data for the third account from the distributed ledger;
compare a first value from the first account data and a third value from the third account data to a threshold;
determine, by the first computing device, the transaction satisfies a transaction policy in response to the first value and the second value exceeding the threshold; and
generate a record in the distributed ledger indicating the transaction transferring the transaction data from the first account to the second account in response to the determination that the transaction satisfies the transaction policy.

12 . The system of claim 11 , wherein the processor is configured to generate the record in the distributed ledger by storing identifications of the first account, the second account, and the third account in the record.

13 . The system of claim 11 , wherein the processor is further configured to:
determine the first account data and the third account data satisfy the transaction policy based on the first account data and the second account data indicating the first account and the second account are each capable of performing the transaction.

14 . The system of claim 11 , wherein the processor is configured to retrieve the first account data from the distributed ledger by retrieving a first account balance of the first account and wherein the processor is configured to retrieve the third account data from the distributed ledger comprises by retrieving a third account balance of the third account.

15 . The system of claim 14 , wherein the processor is configured to retrieve the first account data by aggregating balances from any transactions that were recorded on the distributed ledger that involved the first account.

16 . The system of claim 14 , wherein the processor is configured to retrieve the first account data by retrieving the first account data from a single record in the distributed ledger.

17 . The system of claim 16 , wherein the distributed ledger comprises a blockchain, and wherein the processor is configured to retrieve the first account data from a single record in the distributed ledger by retrieving the first account data from a single block instance that was previously appended to the blockchain.

18 . The system of claim 16 , wherein the processor is configured to generate the record in the distributed ledger by:
updating the first account data based on the transaction; and generating the record in the distributed ledger to include the updated first account data.

19 . The system of claim 11 , wherein the processor is configured to generate the record in the distributed ledger by transmitting one or more messages to one or more computing devices in communication with the distributed ledger, the one or more messages containing a plurality of predetermined transaction attributes
