A system and method for enabling dynamic expiration dates in a payment card. An algorithm executes on a computing device to create a private blockchain that is controlled by an inquiry block exchange.

The security zone comprises multiple modules. These modules include a dynamic smart contract (DSC) execution engine module for generating a DSC hash value that identifies the DSC for the PCH profile metablock. A hyper-ledger fabric module enables dynamic parameters to be stored as an asset in the DSCs. A metablock generator module creates a PCH profile metablock and hashes the data in a subscribed hashing algorithm. The hashed data includes private keys and cryptographic keys in a secured element section of the PCH profile metablock.

Systems and methods for novel uses and/or improvements to blockchains and blockchain technology. As one example, systems and methods are described herein for self-validating digital records that may be transferred in real-time through a cross-network registry. For example, in a conventional system, minting a token (e.g., a digital record) involves writing a self-executing program that defines the transfer rules of the digital record. Once the self-executing program is written, it is deployed on a blockchain, and the digital record is minted by publishing it to a blockchain.

Embodiments described herein provide for a healthcare ecosystem of computing devices participating as nodes of a distributed ledger (e.g., blockchain). The distributed ledger includes NFTs representing corresponding patients, where the initial NET behaves logically as a token scaffold that represents a “digital twin” of the particular patient. The initial patient token represents personal profile data of patient personal data for the patient. The nodes may generate new data and/or new sub-tokens (or other blockchain entry type) representing new data, which the nodes associate with the token scaffold. The sub-tokens contain data for representing physical or digital specimens, health data, and data derived from the health data (e.g., cell lines, organoids, other model systems). As the nodes generate and associate new sub-tokens to the patient's token scaffold over time, the token scaffold graphs and facilitates integration of patient-specific data and evolves into a robust electronic health record (EHR) and digital twin.

Some examples of the present disclosure relate to generating artificially intelligent entities represented on a blockchain using a non-fungible token (NFT). In one such example, a system can generate an NFT on a blockchain. The NFT can represent an artificially intelligent entity. The system can also generate a personality dataset on the blockchain, the personality dataset describing personality characteristics of the artificially intelligent entity. The system can then correlate the NFT to the personality dataset, thereby assigning the personality characteristics to the artificially intelligent entity. Once generated, the artificially intelligent entity may reside in a virtual ecosystem in which it can perform tasks and learn over time.
