One or more embodiments described herein disclose methods and systems that are directed at facilitating access to and retrieval of data concealed on a distributed ledger-based network (DLN) with the use of zero-knowledge proof (ZKP) techniques. The methods and systems allow for the encryption, using an encryption key, of data related to a transaction between participants of the DLN, the encryption of the encryption key using a public key of an auditor of the transaction, and the generation of a ZKP that the encryption key used to encrypt the data corresponds to the encryption key encrypted using the public key such that the encrypted encryption key and/or the encrypted data are available to the auditor after the ZKP is verified by a self-executing code segment of the DLN. The ZKP also includes a proof that the encrypted data includes the transaction data.
