Systems, methods, and computer-readable storage media to track provenance of assets utilizing non-fungible tokens (NFTs). One method includes receiving a provenance request, generating a first non-fungible token (NFT) encapsulated with a first control structure, generating a second NFT encapsulated within a second control structure, and tracking provenance of assets utilizing the first NFT and second NFT.

Tokenized structured provenance tracking

Aspects of this technical solution can include identifying, by an NFT transaction processor, a first localization property corresponding to an NFT that restricts transfer of the NFT to a first locality, identifying, by the NFT transaction processor, a second localization property corresponding to a second NFT account that restricts transfer of the NFT to a second locality, generating, by the NFT transaction processor in response to a determination that the first localization property and the second localization property differ, a container linked with the second localization property, transferring, by the NFT transaction processor in response to the determination, the NFT to the container, and linking, by the NFT transaction processor, the second public and private key pair with the container to transfer the NFT to the second NFT account.

Localization control for non-fungible tokens (NFTs) via transfer by containerized data structures

An aspect can include obtaining, from a device of a user, location data, obtaining, from the device in response to a determination that the location parameter identifies a physical location of a physical environment, a public key of the user, generating, based on the public key and a private key of the user, an NFT linked with the user and the physical environment, determining, in response to a determination that the device satisfies a distance threshold to an entry controller at the physical location, that the NFT and the public key are compatible with a control structure of a smart contract, and transmitting, in response to the determination that that the NFT and the public key are compatible with the control structure of the smart contract, an instruction based on the NFT to modify operation of the entry controller to permit entry to the physical location.

Generation and validation of non-fungible tokens linked with physical environments

A method includes receiving a protection request for an exchange and generating a metadata object including a plurality of outputting attributes for outputting. The method further includes generating a protected NFT including a link with the metadata object. The protected NFT is encapsulated within a control structure that restricts an output of the metadata object. The method further includes signing the protected NFT using at least one of a first private key or a second public key. The method further includes transmitting the signed protected NFT to the remote device and continuously monitoring the exchange. The method further includes detecting, by the control structure, at least one outputting attribute of the plurality of outputting attributes is satisfied and, in response to detecting the at least one outputting attribute is satisfied, outputting at least a portion of the output.

Tokenized structured exchange tracking

A system can obtain, based on a first control structure that identifies a content type, a non-fungible token (NFT) linked to a content object corresponding to the content type, encapsulate the NFT within a container having a second control structure that restricts output by the content object linked to the encapsulated NFT, and generate a control token compatible with a third control structure that restricts output by the container to a destination corresponding to the control token, determine by the third control structure that the control token is compatible with the third control structure, and transmit, by the second control structure and based on the determination that the control token is compatible with the third control structure, the output from the content object to the destination.

Tokenized structured data sharing

A system to track to model asset states and access by utilizing non-fungible tokens (NFTs). The system includes a data processing system including memory and one or more processors to receive a stating request for an asset, obtain, based on a plurality of control structures, a plurality of NFTs, each of the plurality of NFTs including a link with a metadata object including metadata of a state of the asset, encapsulate the plurality of NFTs within a container, receive, from the remote device, a state request for an asset state corresponding to a first NFT, the state request including a security token, obtain, from the metadata of the first NFT, one or more recorded security tokens, compare the security token to the one or more security tokens, and, in response to the security token matching the one or more security tokens, transmit the first NFT to the remote device.
