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.

Minting a physical computing device based on unique key generation, wherein the key generation is configured to create a private-public key pair. In implementations, the key pair may be generated upon initialization of the physical computing device, such that the physical computing device is minted with the key pair. The key pair may be utilized as a token for supply-chain billings, payments, auditing, etc. associated with the physical computing device.

A cross-border payment and clearing system and a cross-border payment and clearing method that are based on the Internet and that do not depend on messages. The system and the method get rid of an existing clearing system based on messages, and high speed and low cost cross-border payment and clearing are implemented by means of communication without messages that is based on the Internet and counterparty transaction of members, and further, a trilateral clearing mode is implemented that ordinary corporations, natural persons, and the like directly submit a cross-border payment request to the clearing system, and the clearing system performs real-time payment and clearing according to a member of a payment corporate that is appointed by the clearing system or that is preferred, so that a large number of intermediate links and message transmission are omitted, and efficiency is greatly improved. The system supports both legal currency clearing and digital currency clearing, and fully uses features of digital currency and locks, releases, and pays out security deposit, to further reduce a risk, and has important uses in the fields of currency clearing, international trade, cross-border electronic commerce, and the like.

A method includes sending, by a trader computing device, an amount of a first digital asset to a digital asset exchange device for an exchange of the amount of the first digital asset to an amount of a second digital asset. The trader computing device includes a trader wallet that stores assignable tokens. The method further includes determining to assign conditional access rights to an amount of the assignable tokens to the digital asset exchange device to back the exchange, locking the amount of the assignable tokens, and providing the conditional access rights to the amount of the assignable tokens to the digital asset exchange device. The method further includes exchanging, by the digital asset exchange device, the amount of the first digital asset to the amount of the second digital asset and sending the amount of the second digital asset to the trader computing device.

A loan process smart contract manages a collateralized loan process for a loan against a collateralized item, the collateralized loan process including tokenizing and locking a collateral token that tokenizes the collateral item, managing distributed appraisal of the collateral item, monitoring terms of the loan, and detecting an unlocking event of the loan for unlocking the collateral token.

A method and device for executing the method to: control an unused transaction output (utxo) stored in a first digital wallet of a first user according to a private key of the first user; generate a transaction for transferring rights over the utxo from the first digital wallet to a second digital wallet; generate a cryptographic hash of the transaction into a unique transaction identification of the transaction; transmit the unique transaction identification of the transaction to a party other than the first user; in response to transmission of the unique transaction identification of the transaction, receive a redeem transaction cryptographically signed by a private key of the party other than the first user; cryptographically sign the received redeem transaction with the private key of the first user; store the redeem transaction in the first digital wallet; and transmit confirmation that the redeem transaction is valid.

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.

The present invention relates to a digital virtual currency transaction system and method which enable a receiver to make digital virtual currency transactions having a block chain regardless of whether an electronic wallet has been opened, and which have a block chain between concerned parties to guide the concerned parties to be able to conveniently make URL-based transactions without recognizing a public address comprised of 32 bytes or more for every digital virtual currency transaction having a block chain between concerned parties. Provided are a system and a method using same, the system comprising: a block chain-based digital virtual currency transaction guide server (100); a giver terminal (200) which is loaded with a giver-side block chain-based digital virtual currency transaction app (210), generates a giver transaction request signal; and a receiver terminal 300 which clicks the receiver transaction selecting URL (A).

Systems and methods for providing blockchain based checks (BC Checks) that may be redeemed without traditional coordination between financial institutions of participants. Some particular embodiments of the present disclosure enable a recipient of a BC check (the payee) to validate the BC check directly through a blockchain hosted at least in part by the financial institution that issued the checks to the network participant using the BC check as payment (the payer) to the recipient. Some embodiments of the present disclosure further enable the payee to redeem the BC check for fiat currency directly through the payer's financial institution (even if the payee and payer do not share the same financial institution).

A method for processing data of transactions in a block chain system which applies a time control to a transfer of assets receives from a first user an asset transferring request, generating an asset transferring permission accordingly. If a current blockchain time meets a first time condition, assets recorded as the content of an asset transfer are allowed to be transferred from a first account address to a second account address. An asset transaction request from a second user can be received, and an asset transaction permission also generated accordingly. If current blockchain time meets a second time condition of the asset transaction permission, the second user and a third user, for asset forwarding or asset return purposes for example, may trade in relation to the permitted asset transaction content. A device for processing such data is also provided.
