In embodiments of the present invention, methods are provided for receiving attributes of an item via a graphical user interface of a tokenization platform. The item attributes may include a number of instances of the item that are available for transaction by a merchant of the item. A virtual representation of the item may be generated based on the item attributes, where the virtual representation is a data structure that stores the item attributes and N digital tokens based on the virtual representation may be generated, where N is an integer equal to the number of items available for transaction and where each digital token is redeemable by an owner of the respective digital token to satisfy the transaction for an instance of the item. Each of the N digital tokens may be cryptographically linked to a respective instance of the virtual representation of the item.

In embodiments of the present invention, systems are provided for handling a set of secure digital tokens, each of which uniquely represents a real-world object, including an interface configured to handle a unique identifier for a unique unit of a real-world object, the object having a set of real-world object attributes, a cryptographic token generation system that generates a unique digital token that has a set of digital attributes that correspond to the set of real-world object attributes, a cryptographic linking system configured to generate a cryptographically secure, one-to-at-least-one link between the unique digital token generated by the cryptographic token generation system and the unique identifier for the unique unit of the real-world object, and an analytics system configured to monitor, track, and report on a set of states, events, and activities of the unique digital token.

In embodiments a system for tokenizing a token is disclosed. The system includes an interface configured to handle a unique identifier a first digital token that is tokenized in accordance with a first protocol. The method also includes a cryptographic token generation system that generates a second digital token, the second digital token is tokenized in accordance with a second protocol. The system further includes a linking system that generates a one-to-at-least-one cryptographic link between the second digital token generated by the cryptographic token generation system and the first digital token, such that the second digital token provides a unique digital tokenization of the first digital token. The system includes a ledger update system that writes the second digital token to a cryptographic ledger in accordance with the second protocol, thereby facilitating transactions involving the first token using the second digital token protocol.

In embodiments, a system for tokenizing tokens is disclosed. The system includes an interface configured to handle a token identifier for a first token, wherein the first token is a cryptocurrency. The system also includes a token generation system that generates a second token that represents a defined quantity of the cryptocurrency represented by the first token. The system also includes a linking system configured to generate a one-to-at-least-one link between the second token and the first token, such that the second token provides a unique tokenization of the first token. The system includes a messaging system integrating the handling of cryptocurrency exchanges into a messaging protocol, wherein the messaging system automatically executes exchange of the cryptocurrency from a first user to a second user upon sending a message from the first user to the second user that has the second token embedded therein.

In embodiments of the present invention, systems are provided for tokenizing a token, including an interface configured to handle a unique identifier for a first digital token, wherein the first digital token is a cryptocurrency, a cryptographic token generation system that generates a second digital token that represents a defined quantity of the cryptocurrency represented by the first digital token, a linking system configured to generate a one-to-at-least-one link between the second digital token generated by the cryptographic token generation system and the first digital token, and a transfer system that enables control of a quantity of the first digital token using a workflow that omits interaction by users with a cryptography system.

The techniques herein are directed generally to a “zero-knowledge” data management network. Users are able to share verifiable proof of data and/or identity information, and businesses are able to request, consume, and act on the data—all without a data storage server or those businesses ever seeing or having access to the raw sensitive information (where server-stored data is viewable only by the intended recipients, which may even be selected after storage). In one embodiment, source data is encrypted with a source encryption key (e.g., source public key), with a rekeying key being an encrypting combination of a source decryption key (e.g., source private key) and a recipient's public key. Without being able to decrypt the data, the storage server can use the rekeying key to re-encrypt the source data with the recipient's public key, to then be decrypted only by the corresponding recipient using its private key, accordingly.

Provided herein are systems, methods, and networks for tracking user compliance with a health program using a peer-to-peer distributed ledger computer network. Further provided are methods for stabilizing the price of tokens supplied to the distributed ledger computer network using a central authority or off-chain oracle. In some embodiments, the methods of stabilizing the price of tokens is leveraged in the systems and networks disclosed herein.

In a blockchain networking environment, a wallet keying system creates a private key that is used for authorizing user transactions while negating the need for the private key to be hosted on a user device or in a user application such as a blockchain wallet. The private key is fragmented and stored in a distributed fashion to prevent unauthorized access. To ensure scalability and network performance, a shard system allows the movement of users and user applications and tools within a decentralized and distributed blockchain network to enable better network balance and utilization of available resources at the local node level. A network provisioner is permitted to impose and adjust restrictions applied to a wallet or on blockchain tokens with the restrictions either being adjusted based on milestones and measured parameters or manually.

An electronic device is provided. The electronic device includes a memory, a communication circuit, and a processor, wherein the memory stores instructions which, when executed, cause the processor to receive a message from an external electronic device, the message including a blockchain address corresponding to a blockchain account and an identifier corresponding to at least one blockchain transaction related to the blockchain address, obtain blockchain transaction information related to the identifier from a node included in a blockchain network related to the blockchain address using the communication circuit, based on a request for remitting cryptocurrency to the blockchain address, when the blockchain transaction information obtained from the node corresponds to the blockchain address, remit the cryptocurrency to the blockchain address via the blockchain network, using the communication circuit and, when the blockchain transaction information obtained from the node does not correspond to the blockchain address, refrain from remitting the cryptocurrency to the blockchain address via the blockchain network.

A method for securing smart contracts in a blockchain includes receiving in the blockchain a contract creation transaction having a control flow graph (CFG) and contract code for a smart contract to be created. The contract creation transaction is verified by checking a signature of a creator of the smart contract and determining that the CFG is correct based on the contract code. The verified contract creation transaction is included as a block in a distributed ledger of the blockchain.
