Provided are systems and methods for auto-performing short-term investments on an intermittent basis via a crypto-network and returning the principal and interest before the cash is needed. As an example, the method may include installing a blockchain smart contract on a blockchain ledger with read access to content stored on the blockchain ledger, establishing a communication channel between a monitoring engine and the blockchain smart contract, configuring the monitoring engine to identify stop conditions from content stored on the blockchain ledger, monitoring the blockchain ledger for updates to content stored on the blockchain ledger via the communication channel and detecting a stop condition based on an update to the blockchain ledger via the monitoring engine, and in response the detected stop condition, transmitting a request to the crypto-exchange server to return the funds to the external data source.

A method for issuing non-fungible tokens based on time-context data to be used for supporting transactions of historical time slots includes steps of: (a) an NFT platform server, in response to acquiring a specific intention, determining whether at least one specific issuance condition for at least one specific token corresponding to at least one specific historical time slot is satisfied; and (b) the NFT platform server, in response to determining that the specific issuance condition is satisfied, transmitting a specific transaction indicating that an issuance of the specific token is valid to at least part of nodes included in the blockchain network, to thereby update the nodes in the blockchain network and thus enable the issuance of the specific token corresponding to the specific historical time slot.

A non-transitory computer readable storage medium has instructions executed by a processor to maintain digital identities. Each digital identity has identity attributes different than identity attributes associated with a real individual utilizing the digital identity. Each digital identity has an associated attribute for compartmentalized network activity. Interactions between the digital identities and a virtual card provider are supported to secure virtual cards for the digital identities. Interactions between the digital identities and a persona management application are brokered, including delivering the virtual cards for the digital identities to the persona management application.

A networked computer system for storing promotional awards associated with non-fungible tokens (NFTs) is described herein. The networked computer system includes a master engagement record blockchain system including a plurality of master engagement records associated with NFTs, an engagement computer server system, and a plurality of kiosk terminals. A kiosk processor is programmed to capture a dynamic NFT verification (DNV) displayed on a user's mobile device via a kiosk camera and display the plurality of engagement activities via the display touchscreen. The processor of the engagement computer server system performs algorithm steps including determining a promotional award associated with the user selected engagement activity upon receiving the engagement activity completion message from the kiosk processor, and recording a master engagement record to the master engagement record blockchain system associating the determined promotional award with the user owned NFT.

Computing devices, methods, systems, and computer-readable media for analyzing requests to perform cold restores of cryptocurrencies are described herein. A computing device may receive a request for a cold restore of one or more cryptocurrencies stored by a digital wallet. The one or more cryptocurrencies may be identified, and data may be received from a database. The computing device may determine, based on the data, a risk score associated with the transfer of the one or more cryptocurrencies from a cold state to a hot state. The risk score may be generated using a machine learning model, such as a machine learning model that may be trained to output a risk score associated with a cold restore based on recent transaction activity. The computing device may output, based on comparing the risk score to a threshold, an indication of whether the request should be granted.

A system for transacting in an environment with intermittent connectivity via a network backbone to a blockchain. A merchant device transmits a set of credentials for an ad hoc network to a buyer device and establishes a private peer-to-peer ad hoc network connection with the buyer device. It then conducts a transaction with the buyer device via the private peer-to-peer ad hoc network. If no network connection is available to a transaction blockchain, the merchant device stores a record of the transaction until such network becomes available and later sends the record of the transaction to the transaction blockchain.

Methods, systems, computing platforms, and storage media for creating and deploying location-based event-triggered cryptographic tokens for gated access to location-based experiences are disclosed. Exemplary implementations may: store location-based criteria; store a smart contract comprising computer code configured to mint a token and allocate the token to a user wallet in response to a user's location satisfying first location-based criteria; obtain location information from a user device; in response to a determination that the location information satisfies the location-based criteria, invoke the smart contract to mint a token and allocate the token to a user wallet; store a token-gated resource identifier for a resource and token criteria; and in response to a determination that the user satisfies the token criteria, grant the user access to the resource.

A digital identity wallet system includes a web wallet and Identity Cloud. The web wallet leverages browser APIs, platform authenticators, and secure device hardware to create, store, and use cryptographic keys. The Identity Cloud stores data encrypted on a per-user basis, so only a specific user can decrypt it, using the web wallet in a particular web browser, on a particular device. The web wallet, in conjunction with the browser and device, leverages cryptographic keys to perform all cryptographic operations locally. This allows the Identity Cloud to only handle sensitive data that's already been encrypted on a per-user basis before it receives it.

A non-fungible blockchain token (NFT) transferable from wallet to wallet on a blockchain represents ownership of a physical diamond custodied in a secure vault. The NFT can be sold and resold to investors wishing to use the diamond as a store of value. The NFT owner, who may only be known by a blockchain wallet address, can communicate with the custodian, the issuer, auditors, and more by writing signal messages into the blockchain NFT. A diamond custody controller unit at the custodian includes a trusted program module to handle private cryptographic key functions and to output retrieval and shipping instructions when a signal message indicates the NFT owner instructs the custodian to move the diamond to a new custodian. The NFT owner can also write signal messages into the NFT to instruct other parties, such as auditors, to perform services relating to the diamond.

Some embodiments of the present disclosure relate to a computer implemented method of storing data associated with an asset on a blockchain. Other embodiments relate to a computer implemented method of retrieving data associated with an asset that is stored on a blockchain. The methods are performed on a blockchain node of a blockchain network.
