System and method for identity resolution across disparate distributed immutable ledger networks
A system and method for identifying previously unknown counterparties by registering distributed ledger public keys and/or addresses associated with specific business entities and/or individuals. The system and method are configured to provide tools for administering public facing distributed ledger identifiers using cryptographic proof messaging and transactions made on the Distributed Ledger. It also provides queries and lookups to discover public keys associated with entities and allows users to link identifiers on competing Distributed Ledgers to a disambiguated entity, thereby enabling cross Ledger transactions to occur.
