Systems, methods, and computer-readable storage media of exchanging digital assets using a public key cryptography framework. One method includes encrypting at least one digital asset on an internal ledger and storing the encrypted at least one digital asset on an internal ledger. The method further includes receiving a signed exchange request signed by a first key corresponding with an encrypted digital asset on the internal ledger and providing, to an inter-provider ledger, a second key based on interfacing with the inter-provider ledger based on establishing a first data feed. The method further includes determining the signed exchange request was verified. The method further includes updating a central ledger by interfacing with of the central ledger via an application programming interface (API) based on establishing a second data feed and wherein at least one of a plurality of fields of the encrypted digital asset is a universal field.

Systems and methods of exchanging digital assets using a public key cryptography (PKC) framework

Systems, methods, and computer-readable storage media of template-based digital asset exchanges using a public key cryptography (PKC) framework. One method includes storing a plurality of exchange templates, and receiving a signed exchange request signed by a private key of a public and private key pair associated with a digital asset. The method further includes receiving an environmental dataset, and selecting, utilizing the environmental dataset, an exchange template of the plurality of exchange templates. The method further includes populating the plurality of fields of the selected exchange template based on the environmental dataset. The method further includes providing, to a plurality of user devices, a public key, updating a provider ledger, and updating a central ledger.

Systems, methods, and computer-readable storage media of wrapping digital assets. One method includes receiving, from a central provider system, a digital asset signed by a central private key associated with a digital asset on a central ledger, and verifying the digital asset based on a central public key. The method further includes updating the digital asset including an assignee field, and receiving an attribute for a second assignee of the digital asset. The method further includes wrapping utilizing the private key of the public and private key pair, the digital asset with the attribute and receiving environmental data. The method further includes determining the at least one condition of the attribute is satisfied, and updating the assignee field.

Systems and methods of digital asset wrapping using a public key cryptography (PKC) framework

Systems, methods, and computer-readable storage media of exchanging digital assets using a public key cryptography framework. One method includes storing a plurality of digital assets on an internal ledger, and receiving a signed exchange request signed by a private key of a public and private key pair associated with a digital asset on the internal ledger, wherein the signed exchange request includes a destination address of an inter-provider ledger. The method further includes providing, to the inter-provider ledger, a public key of the public and private key pair based on interfacing with the destination address of the inter-provider ledger via a first API, and determining, from the inter-provider ledger, the signed exchange request was verified. The method further includes updating the internal ledger by removing the public and private key pair, and updating a central ledger by interfacing with a central address of the central ledger via a second API.
