Gaming system, gaming device and method for utilizing bitcoins

The gaming system may enable a player to wager an amount of bitcoins on one or more plays of one or more primary or base games. If a player wagers an amount of bitcoins on a play of a game, the gaming system may determine and display an outcome for the play of the game. The gaming system then may determine if any award may be associated with the determined outcome. If an award having a value greater than zero is associated with the determined outcome, the gaming system may provide the determined award to the player, such as an amount of bitcoins.

Offline virtual currency transaction

A method of conducting an offline virtual currency transaction is disclosed. The method may include steps of generating one or more virtual wallets; depositing certain amount of virtual currency in said virtual wallets; a payer transmitting at least a portion of said virtual currency to a payee through an offline platform; and payee confirming reception of the virtual currency. In one embodiment, the step of transmitting at least a portion of said virtual currency to another user through an offline platform may include a step of scanning a QR (Quick Response) code to transmit the virtual currency. In another embodiment, the virtual currency can also be transmitted through infrared. In a further embodiment, the step of confirming reception of the virtual currency may include a step of said payee deleting private key.

Cryptocurrency infrastructure system

Embodiments of the present invention are directed to methods and systems for managing a cryptocurrency payment network comprising one or more issuer nodes and one or more distributor nodes. Issuer nodes may be granted different rights from distributor nodes with respect to the issuance and distribution of digital currency within the cryptocurrency payment network. A management system server computer may generate unique node verification key pairs for each node in the cryptocurrency payment network, where the node verification key pairs may be used to identify and authenticate issuer nodes and distributor nodes.

Virtual currency bank

Described herein are embodiments of a virtual currency bank that includes a sealed container that includes an exterior surface and defines an interior, a QR code, located on the exterior associated with a public key that is tied to a virtual currency account, in that the QR code may be scanned to access the public key in order to add funds to the virtual currency account, and a private key, located in the interior of the sealed container and associated with the public key, in that the private key must be accessed and read to remove or spend funds from the virtual currency account. The sealed container is sealed in a manner so that the private key cannot be accessed without breaking the seal or the container in a manner that cannot be obscured or undone.

System and method to prevent loss of bitcoins due to address

Aspects of the invention are related to a method for determining whether a transaction message of a digital currency system is valid. The exemplary method comprises: receiving the transaction message, the transaction message referencing in an input a previous output associated with a timeout value; determining whether a time as specified by the timeout value has passed; determining that the transaction message is valid in response to determining that the time as specified by the timeout value has not passed; and collecting the transaction message into a block of a block chain in response to determining that the transaction message is valid.

Method to securely establish, affirm, and transfer ownership of artworks


A method for establishing, confirming, and transferring ownership of digital artworks. The method associates a given artwork to a unique public ID and to an online service. The owner of the artwork is the person who has full access to the online service at the public ID. Confirming ownership of the artwork includes the owner performing an action that demonstrates the owner has full access to the online service at the public ID. Transferring ownership of the artwork includes ( 1 ) transferring access to the account itself, or (2) using the online service's transfer protocol, which may also update the public ID associated with the owner of the artwork.

Transaction signing utilizing asymetric cryptography

Embodiments relate to systems, apparatuses, and methods for performing transaction signing utilizing asymmetric cryptography and a private ledger. A transaction data is signed by a user device using a private key, and may be utilized in an authorization request message without including a real credential of the user. A transaction verification and accounting module (TVAM) can verify the signed transaction data and can continue processing the transaction.

System and method for rating a transaction history

-30- ABSTRACT OF THE DISCLOSURE Described herein is a rating system for rating a transaction history of a digital currency, comprising: a storage system for storing transaction information of the digital currency; an interface for receiving an identifier of at least one account associated with the digital currency and a request for rating the transaction history of the at least one account; a processor communicative with the storage system and the interface; the processor identifying transactions of the at least one account from the transaction information stored in the storage system and assessing the destination of the identified transactions to generate a rating for the at least one account. The rating system may further assess the amount and age of the identified transactions. The rating system may be useful, for example, for peer-to-peer digital currencies such as Bitcoin. Methods for rating a transaction history of a digital currency and computer readable media for providing the same are also described herein.

Digital currency enabled vending machine

A vending machine is described that uses digital currency transactions to enable a user to purchase items from their portable computing device. Using a control system in communication with various components of the vending machine and an internet connection for communicating with a remote digital currency system, such as a bitcoin network, a digital currency processing system executes digital currency transactions and stores the resulting digital currency in a transaction storage repository. The control system initiates dispensing of purchased items based on communication from the digital currency processing system.

Digital currency mining circuitry having shared processing logic

An integrated circuit may be provided with cryptocurrency mining capabilities. The integrated circuit may include control circuitry and a number of processing cores that complete a Secure Hash Algorithm 256 (SHA-256) function in parallel. Logic circuitry may be shared between multiple processing cores. Each processing core may perform sequential rounds of cryptographic hashing operations based on a hash input and message word inputs. The control circuitry may control the processing cores to complete the SHA-256 function over different search spaces. The shared logic circuitry may perform a subset of the sequential rounds for multiple processing cores. If desired, the shared logic circuitry may generate message word inputs for some of the sequential rounds across multiple processing cores. By sharing logic circuitry across cores, chip area consumption and power efficiency may be improved relative to scenarios where the cores are formed using only dedicated logic.
