Abstract

Claims (42)

1. A method of conducting transactions, the method comprising:

generating, by a wallet distributed application for a user, an address for use with a public distributed ledger system and a private key;

generating, by the wallet distributed application, a first transaction to a distributed application in the public distributed ledger system, the generating using the generated address and private key;

transmitting the first transaction to the public distributed ledger system for execution;

upon execution of the first transaction, generating, by the wallet distributed application, a second transaction to a smart contract of a personal distributed ledger system, the generated second transaction containing information identifying the executed first transaction, the identifying information including at least a portion of the executed first transaction and the private key used to sign the first transaction, the personal distributed ledger system being separate from the public distributed ledger system and including only distributed nodes authorized by the user, the authorized distributed nodes including a validator node hosted by a financial institution system;

transmitting, by the wallet distributed application, the second transaction to at least one distributed node of the personal distributed ledger system;

retrieving, by the validator node hosted by the financial institution system, at least a portion of the identifying information from the personal distributed ledger system by executing a read call to the smart contract of the personal distributed ledger system;

determining, by the financial institution system, whether to authorize the user associated with the personal distributed ledger system to further conduct transactions in the public distributed ledger system using tokens of the public distributed ledger system minted by the financial institution system, the determining based on the retrieved identifying information; and

in response to determining to authorize the user, minting, by the financial institution system based on the retrieved identifying information, the tokens of the public distributed ledger system for use by the user to conduct further transactions in the public distributed ledger system.

2. The method of claim 1 , wherein the information identifying the executed first transaction includes an execution receipt for the first transaction.

3. The method of claim 1 , further comprising:

receiving, by the wallet distributed application, an invocation to sign the first transaction, the invocation including the first transaction, the invocation received from the distributed application of the public distributed ledger system.

4. The method of claim 1 , further comprising:

generating a third transaction utilizing the minted tokens.

5. At least one non-transitory machine-readable storage medium having program instructions, which when executed by processors cause a method of conducting transactions to be performed, the method comprising:

generating, by a wallet distributed application for a user, an address for use with a public distributed ledger system and a private key;

generating, by the wallet distributed application, a first transaction to a distributed application in the public distributed ledger system, the generating using the generated address and private key;

transmitting the first transaction to the public distributed ledger system for execution;

upon execution of the first transaction, generating, by the wallet distributed application, a second transaction to a smart contract of a personal distributed ledger system, the generated second transaction containing information identifying the executed first transaction, the identifying information including at least a portion of the executed first transaction and the private key used to sign the first transaction, the personal distributed ledger system being separate from the public distributed ledger system and including only distributed nodes authorized by the user, the authorized distributed nodes including a validator node hosted by a financial institution system;

transmitting, by the wallet distributed application, the second transaction to at least one distributed node of the personal distributed ledger system;

retrieving, by the validator node hosted by the financial institution system, at least a portion of the identifying information from the personal distributed ledger system by executing a read call to the smart contract of the personal distributed ledger system;

determining, by the financial institution system, whether to authorize the user associated with the personal distributed ledger system to further conduct transactions in the public distributed ledger system using tokens of the public distributed ledger system minted by the financial institution system, the determining based on the retrieved identifying information; and

in response to determining to authorize the user, minting, by the financial institution system based on the retrieved identifying information, the tokens of the public distributed ledger system for use by the user to conduct further transactions in the public distributed ledger system.

6. The at least one non-transitory machine-readable storage medium of claim 5 , the method further comprising:

generating a third transaction utilizing the minted tokens.

7. The at least one non-transitory machine-readable storage medium of claim 5 , wherein the information identifying the executed first transaction includes an execution receipt for the first transaction.

8. The at least one non-transitory machine-readable storage medium of claim 5 , the method further comprising:

receiving, by the wallet distributed application, an invocation to sign the first transaction, the invocation including the first transaction, the invocation received from the distributed application of the public distributed ledger system.

9. A system for conducting transactions, the system comprising:

a host computing system including at least one processor configured to execute program instructions to cause the following to be performed:

generating, by a wallet distributed application for a user, an address for use with a public distributed ledger system and a private key;

generating, by the wallet distributed application, a first transaction to a distributed application in the public distributed ledger system, the generating using the generated address- and private key;

transmitting the first transaction to the public distributed ledger system for execution;

upon execution of the first transaction, generating, by the wallet distributed application, a second transaction to a smart contract of a personal distributed ledger system, the generated second transaction containing information identifying the executed first transaction, the identifying information including at least a portion of the executed first transaction and the private key used to sign the first transaction, the personal distributed ledger system being separate from the public distributed ledger system and including only distributed nodes authorized by the user, the authorized distributed nodes including a validator node hosted by a financial institution system;

transmitting, by the wallet distributed application, the second transaction to at least one distributed node of the personal distributed ledger system; and

a validator computing system including at least one processor configured to execute program instructions to cause the following to be performed:

retrieving, by the validator node hosted by the financial institution system, at least a portion of the identifying information from the personal distributed ledger system by executing a read call to the smart contract of the personal distributed ledger system;

determining, by the financial institution system, whether to authorize the user associated with the personal distributed ledger system to further conduct transactions in the public distributed ledger system using tokens of the public distributed ledger system minted by the financial institution system, the determining based on the retrieved identifying information; and

in response to determining to authorize the user, minting, by the financial institution system based on the retrieved identifying information, the tokens of the public distributed ledger system for use by the user to conduct further transactions in the public distributed ledger system.

10. The system of claim 9 , wherein the information identifying the executed first transaction includes an execution receipt for the first transaction.

11. The system of claim 9 , wherein the host system is further configured to cause the following to be performed:

receiving, by the wallet distributed application, an invocation to sign the first transaction, the invocation including the first transaction, the invocation received from the distributed application of the public distributed ledger system.
