Abstract

Claims (78)

1. A system for integrating blockchain functions and external systems using user-specific digital assets for use in secure encrypted, communications across disparate cryptography-based computer network, the system comprising:

one or more processors; and

a non-transitory computer readable medium comprising instructions recorded thereon that when executed by the one or more processors cause operations comprising:

receiving, from a user-specific digital storage resource application on a user device, a first user input to perform an off-chain function with a first content provider;

in response to the first user input, determining an off-chain characteristic corresponding to the off-chain function;

receiving a second user input selecting a non-fungible token to compare to the off-chain characteristic;

in response to the second user input, generating a communication to an off-chain resource identified by the non-fungible token for authorization to perform the off-chain function using the non-fungible token, wherein performing the off-chain function causes an off-chain metadata property for the non-fungible token to be modified, wherein the off-chain resource comprises a centralized data storage source for storing metadata for the non-fungible token, wherein metadata property updates are communicable between a smart contract governing the non-fungible token and the off-chain resource using a blockchain oracle, wherein the blockchain oracle is controlled by the off-chain resource, and wherein the off-chain resource is identified based on a Universal Resource Identifier (“URI”) encoded in the non-fungible token;

in response receiving the authorization to perform the off-chain function, receiving, from a user, a user approval request to perform an on-chain blockchain function corresponding to the off-chain function; and

generating, from the user-specific digital storage resource application on the user device, a confirmation of the on-chain blockchain function in response to the user approval request, wherein the confirmation is based on a private key for the user-specific digital storage resource application, and wherein generating the confirmation causes performance of the on-chain blockchain function and a modification of the off-chain metadata property.

2. A method for integrating blockchain functions and external systems using user-specific digital assets for use in secure encrypted, communications across disparate computer network, the method comprising:

3. The method of claim 2 , wherein the performance of the blockchain function comprises:

a first performance portion between the user-specific digital storage resource application and to an on-chain receiver for the off-chain resource; and

a second performance portion between the off-chain resource and the first content provider.

6. The method of claim 2 , further comprising:

in response to determining the off-chain characteristic corresponding to the off-chain function, determining a plurality of non-fungible tokens to compare to the off-chain characteristic; and

generating for simultaneous display in a user interface, icons for the plurality of non-fungible tokens to compare to the off-chain characteristic.

7. The method of claim 2 , wherein the authorization to perform the off-chain function using the non-fungible token comprises:
