A computer system comprises a logic system, and, operatively coupled to the logic system, a computer-memory system holding instructions that, when executed by the logic system, cause the computer system to: receive a token-behavior selection corresponding to a real-world asset to be tracked on a virtual ledger; receive a virtual-ledgerarchitecture selection identifying a provider-defined architecture of the virtual ledger; construct a template for registration of a token class on the virtual ledger according to the provider-defined architecture of the virtual ledger, wherein each new token instantiated from the token class exhibits a set of behaviors determined by the token-behavior selection; and provide access to the template to a client computer device.

In essence, the proposed network is meant to provide a platform for prompt pet recovery. Through the establishment and integration of an IoT network consisting of smart pet collars with digital wallets, event triggers which alert a network of individuals when a pet has escaped with available location information, and private user profiles so that those who recover lost pets can be easily rewarded, the proposed network will establish incentives for the decentralized recovery of lost and endangered pets.

Since this system will allow owners to increase the reward incentive on the fly, and individuals recovering the animals are rewarded on a first come first serve basis; this network will establish an environment in which a decentralized community may compete to be the first one to save the animal.

An automated banking machine includes at least one reader that is operative to read indicia from data bearing items that is usable to identify financial accounts. The machine further includes at least one input device, a cash dispenser and a controller. The controller is operative to cause a determination that the read indicia corresponds to a user financial account upon which a transaction is authorized to be conducted through the machine. Responsive at least in part to the determination and at least one transaction selection input corresponding to a dispense of at least one virtual item of value, the controller is operative to cause the user to be provided with a virtual item of value having no physical constituents, but that is perceivable visually through at least one display of a wearable device worn by the user, which wearable device enables the user to visually perceive simultaneously physical surroundings in a direct field of view of the user and visual outputs through at least one display of the wearable device. The wearable device is also operative to enable the user to visually and audibly perceive a service representative.

In a method of providing cryptocurrency cashback using blockchain technology, in which when cryptocurrency is transferred from the payer's electronic wallet to the affiliated store's electronic wallet according to payment via cryptocurrency using blockchain technology, the payment server 200 provides cryptocurrency cashback, an embodiment of the disclosure provides credits proportional to the amount of payment, as cashback, to the payer's credit electronic wallet, and the affiliated store receiving the amount of payment deducts points proportional to received points from the received points and stores in the affiliated store's credit electronic wallet.

Provided is technology for enabling an ordinary user to generate a virtual currency that is data created as crypto cash in the true sense of the word.

A user ID and amount information that are input to a user terminal by a user are sent from the user terminal to a settlement device (S913). Upon receiving the user ID and amount information, the settlement device performs a credit determination (S922), and transmits permission information to the user terminal (S923). At the user terminal, upon receiving the permission information, original data that combines the user ID and the amount information is generated (S915), the original data is encrypted and thereby converted to virtual currency encryption data (S916), and virtual currency data including the virtual currency encryption data is generated (S917). The authenticity of the virtual currency data is guaranteed by the fact that the settlement device which received the virtual currency data could decrypt the virtual currency encryption data (S925).

The present method and system, describes a practice for configuring a computer to run end user software applications, utilizing a portion of the end users computing power, to solve hashing algorithms for mining crypto currencies, and depositing them into a crypto currency account. The crypto currency account will be held by a company, person or group of people, hereinafter referred to as the Entity. The Entity will design the end user software application, to allow the end user to configure the amount of processing power allocated for mining the crypto currency. The more power the end user allows for mining the crypto currency, the more redeemable tokens the end user will generate for exchanging, or, purchasing additions for their software application, provided by the Entity.

An apparatus, computer-readable medium, and computer-implemented method for creating and managing a distributed ledger non-fungible token data structures that represent the liquidity function for any two distinct representations of assets. The representations may be different assets or a single asset type with different characteristics including ledger, network, jurisdiction, availability, etc. The liquidity function is the mechanism to transform or exchange the asset including the pricing function, fees, and delivery mechanism. The investment performance of the liquidity token can be proportional to the demand for liquidity for the pair of assets.

Systems and methods for anonymous cryptocurrency transactions are disclosed. A method may include: receiving, from the electronic device associated with a sender of a cryptocurrency transaction, a zero-knowledge statement comprising a shuffled and anonymized list of participants comprising the sender, a receiver of the cryptocurrency transaction, and a plurality of decoy participants, a transfer amount, and a remaining balance, and a secret witness, wherein each participant is associated with an index; generating one-out-of-many proofs for the sender and the receiver based on their associated indices; generating a Basic Zether proof for the transfer amount and the remaining balance; conducting many-out-of-many proofs with parameters chosen for an anonymous payment setting; and constructing a zero-knowledge proof for the zero-knowledge statement. The sender sends an ordered list of the participants and the zero-knowledge proof to a verifier using the FiatShamir transform, and the verifier verifies the zero-knowledge proof.

Various embodiments relate to a method for managing information in a database. The method includes injecting a transaction into a first blockchain and injecting the transaction into a second blockchain, where the first blockchain and the second blockchain are in a same blockchain network. The first blockchain processes the transaction based on a first set of rules and the second blockchain processes the transaction based on a second set of rules different from the first set of rules. The second blockchain is a private blockchain that excludes one or more participants of the first blockchain.

This invention relates to distributed ledger system implemented as a cryptocurrency or platform for digital commerce. More specifically, this invention relates a system and method for increased transaction and settlement speed using a zero confirmation directed acyclic graph (ZDAG). The invention allows for increased transaction and settlement speed at point of sale for merchants and consumer applications by implementing concurrent processing of transactions with fault tolerance, minimum latency period check, and time based sort of transactions.
