A system for monitoring consumption of digital content by a user includes a display device, a memory circuit maintained on one or more non-transitory computer-readable media, and a processing circuit. The processing circuit identifies the progress of the user through the digital content presented on the display device. The digital content includes a collection of micro content blocks, the progress of the user being at least dependent on one or more of a plurality of predefined parameters. The processing circuit identifies a computer-executable progress score of the user based on the progress identified for the user and defines a computer-executable reward value for the user based on the progress score of the user upon successful achieving at least a defined level of the progress. The processing circuit allows the user to redeem the computer-executable reward value as an equivalent transactional amount upon submission of the progress.

Disclosed herein are system, method, and device embodiments for time-based trust token (TBTT) depreciation. In an example embodiment, a service provider system (e.g., a service provider and API service) may receive a connection request including a demographic attribute associated with a first client account from a partner device, match the demographic attribute to client information associated with the first client account, send the partner device a connection request identifier and a URL including a depreciating token, and authenticate a second client account via a login page associated with the URL. Further, the service provider system may receive a verification request including the connection request identifier and the depreciating token, determine a security context of the depreciating token based on a depreciation function and the verification request, and determine, based on the security context, whether to create a connection between the second client account and partner device within the service provider system.

A system and method for defining and using a virtual currency may include associating a fraction of a currency with at least one of: a history, an attribute, and a constraint; and selecting a usage of the fraction, in a monetary transaction, based on the at least one of: the history, the attribute and the constraint.

The application describes generation of a data structure that enables comparison of any diamond to any other diamond. The data structure is generated via a sampling process and a computer system for acquisition of diamonds of a valid statistical sample having a predefined sample size. The process comprises tabulating the frequencies that diamonds of various grade combinations are available in an overall population of diamonds, then using a bidding process described herein to acquire a valid statistical sample of diamonds. The data for the sample of diamonds are then inputted into a Linear Programming and Mixed-Integer optimizer configured to sort all diamonds of the sample into sets with a median that is a minimal distance from the median on a scarcity basis, subject to various constraints, such as the number of diamonds in each set and a minimum total carat weight.

A diamond asset comprising one or more diamonds and an encryption chip is used to asset-back a cryptographic token that can be used to conduct transactions. A user device executes an application programming interface configured to access a blockchain that stores a smart contract associated with the cryptographic token backed by the value of the one or more diamonds. When the user device receives an instruction to perform a transaction related to the cryptographic token, the user device causes the encryption chip to sign the smart contract. In response to determining that the smart contract was signed by the encryption chip, the user device causes the transaction to be performed.

A diamond asset comprising one or more diamonds and an encryption chip is used to asset-back a cryptographic token that can be used to conduct transactions. The cryptographic token is written to a blockchain using a smart contract that is configured to enable a transaction associated with the token in response to two or more of: a signature by the encryption chip, a signature by the owner of the diamond asset, and a validation of a visual layout of the diamond asset.

A market maker system associated with a diamond-backed cryptographic exchange stores for each of a plurality of diamonds, a rating of the diamond according to each of multiple properties. The system receives ratings of a target diamond for each of the multiple properties. From the stored diamond ratings, the system selects one or more diamonds with ratings within a threshold distance from a specified rating of the target diamond. A dynamic order listing the selected diamonds is generated.

Described in this application is a secured smart cabinet having a plurality of retractable shelves mounted therein for storing a plurality of assets with wireless encryption chips for authentication sealed with each asset. Each shelf is partitioned into a plurality of compartments configured to hold an asset and to enable wireless communication between a wireless senor and a wireless encryption chip. A processing system is configured to command the wireless sensors to audit, authenticate and interact with the wireless encryption chip in the asset and exchange data between the processing system and an authentication server. The exchange of data could include receiving commands from and sending authentication results to the authentication server. The smart cabinet also includes a network device to enable the exchange of data between the processing system and the authentication server.

A system and corresponding method exchange a nonfungible token (NFT) via blockchain cross-chain fungible token transfers. The system comprises first and second blockchains. The first blockchain holds the NFT in a first escrow digital wallet. The NFT is available for trade by a seller and is associated with a trade value. The first blockchain monitors a balance of fungible tokens, owned by a buyer, that are transferred from a second blockchain to a second escrow digital wallet of the first blockchain. In response to detecting that the balance monitored represents the trade value, the first blockchain transfers, simultaneously, (i) the NFT from the first escrow digital wallet to a first digital wallet of the first blockchain, the first digital wallet owned by the buyer, and (ii) the balance of fungible tokens from the second escrow digital wallet to a second digital wallet of the second blockchain, the second digital wallet owned by the seller.

Printer sharing is disclosed. In a method thereof, printers, including corresponding network addresses, are identified for peer-to-peer print services. Prices are obtained for the peer-to-peer print services associated with the printers. A website- or app-accessible platform (platform) is provided for coordinating availability and pricing for the peer-to-peer print services of the printers. A user interface is provided to select a printer of the printers at a price of the prices. A print job is forwarded from the platform to the selected printer of the printers. The print job is printed by the selected printer A payment associated with the price is credited to an account associated with the selected printer.
