Claim 22:
23. A method, comprising:
receiving, at a device of a first user and from a device of a second user, the device of the first user and the device of the second user part of a common zero-knowledge proof (ZKP)-enabled distributed ledger-based network (DLN), a request to determine whether or not the second user has access to an account on the ZKP-enabled DLN, the account identified on the ZKP-enabled DLN by a public key of an asymmetric key pair and having sent and/or received at least one token representing a physical off-the-DLN asset on the ZKP-enabled DLN before receiving the request;
retrieving, by the device of the first user and in response to the request and from the ZKP-enabled DLN, a result of a verification of a ZKP computed by a self-executing code segment on the ZKP-enabled DLN,
the ZKP (i) generated and provided to the self-executing code segment by a device of the second user and (ii) including the ZKP that the second user has access to a private key of the asymmetric key pair; and

generating, based on the retrieved result, a confirmation determining whether or not the second user has access to the account.
