Systems and methods for selling virtual items on multiple online sales platforms simultaneously are disclosed. Exemplary implementations may: receive a sales request that indicates the selling user will be offering for sale a particular virtual item through at least two online sales platforms simultaneously; assign ownership of the particular virtual item temporarily to a holding account; generate sales listings of the particular virtual item for publications on the at least two online sales platforms; effectuate the publications of the sales listings; receive indications of offers to purchase the particular virtual item; determine an accepted offer that is accepted; notify the at least two online sales platforms of whether the offers have been accepted or denied; identify a buyer's account of the buying user; effectuate assignment of the ownership of the particular virtual item to the buyer's account.

A two-coin mechanism for maintaining a stable value of cryptographic coinage traded in a decentralized market exchange without requiring a reserve. A pegged cryptographic token and a variable-priced cryptographic token are both traded in the reserveless decentralized market exchange. The pegged cryptographic token and the variable-priced cryptographic token are value related based on a cryptographic exchange rate. Whenever a market transaction is processed (such as a buy or sell order), at least one of a destruction operation and a creation operation are performed. The destruction operation destroys at least one of the pegged cryptographic token and/or the variable-priced cryptographic token, while the creation operation creates new ones of the pegged cryptographic token and/or the variable-priced cryptographic token. The two-coin mechanism thus implements a decentralized and algorithmic monetary policy that removes and/or deposits cryptographic tokens to/from the reserveless decentralized market exchange to alter supply and to maintain stable coinage values.

A system for transacting blockchain assets includes a blockchain engine with an encryption tool configured to generate multiple encryption hashes to create a sequence of encrypted data blocks storing multiple blockchain assets and transactions thereof for multiple users, a wallet tool to process user requests for asset transactions between one or more users of one or more blockchains, facilitating wallet to wallet transactions, wallet to smart contract transactions, and record-keeping, and a statistics tool to provide analytics information about the asset transactions. The system also includes a portfolio management engine with an aggregator tool to aggregate assets for each user and across one or more blockchains to provide to the statistics tool, and a smart contract tool to provide secure contracts for two or more parties involved in the asset transactions. A method for performing asset transactions in blockchains with the above system is also provided.

Systems and methods are provided to mitigate flaring of natural gas. A natural gas processing system may process raw natural gas into a fuel gas stream that may be used to power any number of on-site power generation modules. In turn, the power generation modules may convert the fuel gas stream into an electrical output, which may be employed to power any number of distributed computing units housed within one or more mobile data centers. In certain embodiments, the distributed computing units may be adapted to mine cryptocurrency or perform other distributed computing tasks to generate revenue.

A computer-implemented method of determining the validity of a token (T) associated with a quantity of cryptocurrency is provided. In some embodiments, the method comprises: a second user (B) receiving, over a communications network, a first transaction comprising a transfer of the token (T) from a first user (A) to the second user (B), querying a peer-to-peer distributed ledger to determine whether an authenticated transaction associated with the token (T) can be identified, wherein the authenticated transaction comprises a previous transaction associated with the token (T) and wherein the token (T) has been authorised and responsive to identifying an authenticated transaction, determining that the token (T) is valid. In some embodiments, the method comprises: a second user: receiving, over a communications network, a first transaction comprising a transfer of the token from a first user to the second user; querying a title registry database to determine if a second transaction comprising a transfer of the token is recorded in the title registry database; and responsive to determining that the second transaction is recorded in the title registry database, determining that the token is valid.

Disclosed herein are systems, methods, and devices for transaction methods for mobile wallet operations in a casino. Various embodiments are directed to applying funds to a user's mobile wallet by transactions at a kiosk, cage, Peripheral System, or other system of the casino. Embodiments are also directed to applying credit to an electronic gaming machine of the casino. Embodiments are also directed to returning or redeeming credit from an electronic gaming machine of the casino to the user. Embodiments are also directed to transferring credit from a mobile wallet to external funds.

Methods and systems are presented for providing comprehensive payment transaction services through a digital wallet. The digital wallet enables a user to conduct an electronic transaction with a merchant or another user. In one aspect, the digital wallet may modify a payment arrangement of the electronic transaction. For example, the digital wallet may determine a first payment arrangement that specifies one or more financial instruments and a payment deferral time period for the electronic transaction. Subsequent to processing the electronic transaction, the digital wallet may determine a different, second payment arrangement for the electronic transaction. The digital wallet may modify the electronic transaction based on the second payment arrangement without canceling the electronic transaction. In another aspect, the digital wallet may manage rewards by dynamically withholding rewards, releasing the rewards, and/or distributing at least portions of the rewards to different users.

Systems and methods for predicting and making payments via preferred payment methods include predicting a preferred funds transfer method of a payee, generating a token based on the predicted preferred funds transfer method, providing the token to a payee device, receiving an input from the payee device indicating an agreement with the predicted preferred funds transfer method, and initiating, in response to the input, an electronic funds transfer from a source account of the payer to the payee.

Blockchain-based, smart contract platforms have great promise to remove trust and add transparency to distributed applications. However, this benefit often comes at the cost of greatly reduced privacy. Techniques for implementing a privacy-preserving smart contract is described. The system can keep accounts private while not losing functionality and with only a limited performance overhead. This is achieved by building a confidential and anonymous token on top of a cryptocurrency. Multiple complex applications can also be built using the smart contract system.

A system and method is disclosed for evaluating a plurality of cryptocurrencies, the method comprising monitoring and storing volatility data for a plurality of cryptocurrency exchanges; analyzing the stored volatility data to generate one or more risk forecasts indicating risks associated with purchasing cryptocurrency through each of the cryptocurrency exchanges; determining a number of transaction factors for purchasing cryptocurrencies and selecting a cryptocurrency based on the transaction factors.
