Systems and methods for managing digital assets and digital asset transactions

A method, comprising:

• receiving, by one or more processors from a first blockchain registry associated with a first computing system, a first provider institution identifier of a first provider institution and a first user identifier of a user, wherein the first provider institution identifier and the first user identifier are recorded in a first distributed ledger database/blockchain;
• receiving, by the one or more processors from a second blockchain registry associated with a second computing system, a second provider institution identifier of a second provider institution and a second user identifier of the user, wherein the second provider institution identifier and the second user identifier are recorded in a second distributed ledger database/blockchain;
• determining, by the one or more processors, a universal unique identifier for the user based at least in part on the first provider institution identifier, the first user identifier, the second provider institution identifier, and the second user identifier;
• and
• at least one of:
• recording, by one or more processors, the universal unique identifier on a third distributed ledger database/blockchain;
• or
• sending, by one or more processors, the universal unique identifier to the first blockchain registry and the second blockchain registry, wherein the first blockchain registry records the universal unique identifier in the first distributed ledger database/blockchain, and wherein the second blockchain registry records the universal unique identifier in the second distributed ledger database/blockchain.

At least one non-transitory processor-readable medium comprising processor-readable instructions such that, when executed by at least one processor, causes the at least one processor to:

• receive, from a first blockchain registry associated with a first computing system, a first provider institution identifier of a first provider institution and a first user identifier of a user, wherein the first provider institution identifier and the first user identifier are recorded in a first distributed ledger database/blockchain;
• receive, from a second blockchain registry associated with a second computing system, a second provider institution identifier of a second provider institution and a second user identifier of the user, wherein the second provider institution identifier and the second user identifier are recorded in a second distributed ledger database/blockchain;
• determine a universal unique identifier for the user based at least in part on the first provider institution identifier, the first user identifier, the second provider institution identifier, and the second user identifier;
• and
• at least one of:
• record the universal unique identifier on a third distributed ledger database/blockchain;
• or
• send the universal unique identifier to the first blockchain registry and the second blockchain registry, wherein the first blockchain registry records the universal unique identifier in the first distributed ledger database/blockchain, and wherein the second blockchain registry records the universal unique identifier in the second distributed ledger database/blockchain.
