An apparatus, computer-readable medium, and computer-implemented method to facilitate scalable compliance and issuer governance of decentralized financial transactions especially for the trade and transfer of tokenized securities. The resulting Compliance Aware Tokens contain the rulesets to restrict transactions and facilitate regulatory reporting and oversight. The embodied process, includes of a novel combination of compliance workflows, attribute verification tools, smart contracts and other ledger controls, provides a decentralized Attribute Based Access Control (ABAC) capability. ABAC patterns are extended to govern global financial transactions without the need for an active intermediary.

A post-paid transaction data processing method includes: receiving risk search information via a wireless or wired interface, the risk search information including a transaction amount and a transaction user identifier of a post-paid transaction; acquiring, according to the transaction user identifier, a payment channel corresponding to the transaction user identifier; determining a predictive affordable value of the payment channel for the transaction amount based on the payment channel and the transaction amount; and determining a default evaluation result of the post-paid transaction according to the predictive affordable value.

A digital wallet device for storing and securing cryptocurrency, the digital wallet device is electronically disconnected from other digital devices and comprising: a cryptocurrency integrated circuit (IC) that is isolated from any computer interface; a non-transitory computer readable storage medium mounted on the cryptocurrency IC and storing a private key of a cryptocurrency and a public key of the cryptocurrency; a man-machine interface (MMI) for receiving an input from a user; at least one processor mounted on the cryptocurrency IC for executing code to create a cryptocurrency action based on the input and to sign using the private key; and a unidirectional communication hardware for sending said transaction to a communication device for broadcasting said transaction via a network.

In at least one embodiment, the present invention provides a systems and methods for executing an electronic commercial transaction between an electronically authenticated first and electronically authenticated second user device both in electronic communication with an electronic communication network and a central distribution server, the first user device having access to a first user account, receiving transaction information from the first user device, sending the transaction information to a second user device having access to a second user account, sending a query, retrieving a query response from at least one of the first user device and the second user device, displaying an advertisement based on the result of the query, receiving transaction confirmation information, and electronically transferring funds from one account to another account.

A payer transaction device enables secure offline transactions using a secure element providing a secure payer account database, a secure ledger database, and a wallet application. While the payer transaction device is not connected to the Internet, the wallet application receives a payee identifier and a transaction amount and verifies that the transaction amount is less than an available payer account balance in the secure payer account database. In response, the wallet application creates a digital token that allocates the transaction amount from the payer account balance to the payee identifier, and records the digital token in a payer secure ledger in the secure ledger database, which reduces the available payer account balance by the transaction amount. The wallet application then transfers the digital token to a payee transaction device over a peer-to-peer wireless connection and, subsequently, the digital token is synchronized with a ledger tracking system through the Internet.

A transport stack may control identity information that may be owned by a user. An information record of the identity information may be stored on a distributed ledger. Transactors may request a viewing-share for the identity information to support transactions with the user. The transport stack may generate a grant record when a transactor is provided with a viewing-share of the identity information. The grant record may be stored on the distributed ledger. The distributed ledger may provide a verifiable record of the identity information content and history of viewing-share grants.

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.

In the disclosed transaction processing system, a system and method are described that increase the ease of access and use of different currency networks by consumers using customizable transaction devices. The customizable transaction devices may be re-programmed prior to or during a currency transaction in accordance with the consensus protocol of the currency network associated with the currency transaction. The currency network further includes one or more host devices, each of which include an interface configured to communicate with a transaction device for the purposes of re-programming a Field Programmable Gate Array (FPGA) of the transaction device according to one or more currency network consensus protocols. Optimizing the performance of transaction devices for proof-of-work or other consensus protocol processing decreases the latency associated with validating currency network transactions, thereby increasing the suitability of cryptocurrency for retail transactions.

Disclosed is system and method for managing transactional interoperability amongst plurality of blockchains, the plurality of blockchains comprising a non-host blockchain and a host blockchain. The server arrangement is configured to append a first transaction to the non-host blockchain, first transaction comprising metadata pertaining to the user transaction, append a second transaction to the host blockchain, the second transaction comprising the first hash address, wherein second transaction triggers an initial smart contract of the host blockchain to store an operational information response at a second hash address in the distributed file storage system; append a third transaction to non-host blockchain, the third transaction comprising the second hash address, append a fourth transaction in the host blockchain, fourth transaction comprising third hash address, wherein the fourth transaction triggers initial smart contract of the host blockchain to update user wallet account based on output generated from the execution of user transaction.

A digital asset delivery network that consists of a cryptographic scheme and a decentralized network that runs on a blockchain. The decentralized network consists of a computer program that interact with the network by issuing electronic messages, computer programs that validate those messages as entries into blockchain and agree on blocks to publish next, and computer programs that run cryptographic multi-party computation protocols. The multi-party computation protocol generates public keys necessary to create cryptocurrency or crypto asset wallets, and also generates the digital signatures necessary to create a transaction for submission to the crypto asset's underlying decentralized network and blockchain.
