    摘要： 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.

    摘要： In an embodiment, a method comprises receiving a request that is configured to cause a transfer of a combined asset from a sender to a recipient, the combined asset including a first asset and a second asset. The method includes generating and sending to a self-executing code segment on a distributed ledger-based network (DLN) a zero-knowledge proof (ZKP) that a plurality of leaf nodes of a hierarchical tree structure representing the combined asset includes the plurality of leaf nodes of the hierarchical tree structure representing the first asset and the plurality of leaf nodes of the hierarchical tree structure representing the second asset. The method also includes receiving, in response to verification of the ZKP by the self-executing code segment, a confirmation confirming a representation of the combined asset on the DLN by a third token associated with the root node of the third hierarchical tree structure.

    摘要： One or more embodiments described herein disclose methods and systems that are directed at providing enhanced privacy, efficiency and security to distributed ledger-based networks (DLNs) via the implementation of zero-knowledge proofs (ZKPs) in the DLNs. ZKPs allow participants of DLNs to make statements on the DLNs about some private information and to prove the truth of the information without having to necessarily reveal the private information publicly. As such, the disclosed methods and systems directed at the ZKP-enabled DLNs provide privacy and efficiency to participants of the DLNs while still allowing the DLNs to remain as consensus-based networks.
