Systems and methods for providing identity assurance for decentralized applications

A method of providing identity assurance for a decentralized application (DApp), the method comprising:

• executing, by at least one node of a distributed ledger system, program instructions of an entitlement smart contract stored on a ledger of the distributed ledger system, to:
• receive a transaction including an indicator of a user authorized to conduct transactions with a DApp smart contract stored on the ledger;
• write the indicator to a list of indicators representing authorized users stored by the entitlement smart contract in the data structure on the ledger of the distributed ledger system;
• receive a call from the DApp smart contract, the call including the indicator representing the user invoking the DApp smart contract;
• and
• provide an output in response to the call to the DApp smart contract indicating the user is entitled to invoke the DApp smart contract.

A method of providing identity assurance for a decentralized application (DApp), the method comprising:

• executing, by the at least one node of a distributed ledger system, program instructions of a registry smart contract stored on a ledger of the distributed ledger system, to:
• receive a call from a DApp smart contract stored on the ledger, the call including an indicator identifying the DApp;
• and
• provide an output to the DApp smart contract in response to the call indicating an address on the ledger corresponding to the entitlement smart contract;
• and
• executing, by at least one node of a distributed ledger system, program instructions of an entitlement smart contract stored on a ledger of the distributed ledger system, to:
• receive a call from the DApp smart contract, the call including an indicator representing a user invoking the DApp smart contract;
• and
• provide an output in response to the call to the DApp smart contract indicating whether the user is entitled to invoke the DApp smart contract.

A non-transitory machine-readable storage medium including program instructions, which when executed by a processor perform a method of providing identity assurance for a decentralized application (DApp), the method comprising:

• executing, by at least one node of a distributed ledger system, program instructions of an entitlement smart contract stored on a ledger of the distributed ledger system, to:
• receive a call from a DApp smart contract stored on the ledger, the call including an indicator representing a user invoking the DApp smart contract;
• perform an entitlement checking function to determine whether a data structure of the entitlement smart contract includes the indicator, wherein the data structure is stored on the ledger, and performing the entitlement checking function includes reading the data structure on the ledger, and determining whether the data structure includes the indicator;
• and
• provide an output in response to the call to the DApp smart contract indicating whether the user is entitled to invoke the DApp smart contract based on the determining whether the data structure of the entitlement smart contract includes the indicator.

A system for providing identity assurance for a decentralized application (DApp), the system comprising:

• at least one processor;
• and
• at least one non-transitory machine-readable storage medium including program instructions, which when executed by the at least one processor cause the at least one processor to perform a method of providing the identity assurance for the DApp, the method including:
• executing, by at least one node of a distributed ledger system, program instructions of an entitlement smart contract stored on a ledger of the distributed ledger system, to:
• receive a call from a DApp smart contract stored on the ledger, the call including an indicator representing a user invoking the DApp smart contract;
• perform at entitlement checking function to determine whether a data structure of the entitlement smart contract includes the indicator, wherein the data structure is stored on the ledger, and performing the entitlement checking function includes reading the data structure on the ledger, and determining whether the data structure includes the indicator;
• and
• provide an output in response to the call to the DApp smart contract indicating whether the user is entitled to invoke the DApp smart contract based on the determining whether the data structure of the entitlement smart contract includes the indicator.
