One approach for blockchain interoperability to be achieved is to employ gateways that permit assets to flow across the relevant networks of blockchains. However, a core requirement for interoperability is the correct identification of computer systems that act as gateways and the correct validation of the ownership of the gateway. A secondary requirement is for a gateway to inquire as to the existence of an entity address (public key) within a given decentralized ledger network. This memo discusses options with regards gateway identification and verification strategies. It looks at addressing the problem from the application layer and from the network layer. It also discusses other options, such as relying on a third-party blockchain-registered identifiers and resolver services}, }
