The presently-disclosed solution provides cross-ledger transfers between distributed ledgers to achieve highly-scalable transaction throughput. Disclosed are methods and instruction code for writing a cross-ledger transfer in a way that effectively transfers value from a source distributed ledger to a target distributed ledger while preventing double spending of the value. This results in the transformation of the ledgers in that the total value in the source ledger is decreased by the transferred value while the total value in the target ledger is increased by the same amount. Also disclosed are system architectures that utilize cross-ledger transfers between multiple distributed ledgers to achieve highly-scalable transaction throughput. Also disclosed are computer apparatus configured to implement cross-ledger transfers between distributed ledgers. Other embodiments and features are also disclosed.

A remittance relay method according to an embodiment of the present invention is provided. The method comprises the steps of: receiving a request for remittance from a remitter device to a recipient account; and on the basis of the received request for remittance, transmitting matching information including transaction information associated with a cryptocurrency to be used for remittance among a remitter, at least two participant devices, and a recipient, to the remitter device and at least two participant devices, wherein the participant devices include a first participant device and a second participant device, a transaction between a remitter and a first participant is made in a first currency, and a transaction between a second participant and a recipient is made in a second currency different from the first currency.

Among other things, a method performed by a certification authority includes receiving a request from a first entity for the first entity to conduct cryptocurrency transactions. The request includes information identifying the first entity and a public key of the first entity. A digital signature of the public key of the first entity is generated using an encryption key of the certification authority. A certification associated with the first entity is stored. The certification includes the digital signature and the public key of the first entity.

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for avoiding double-spending problem in read-write set-model-based blockchain technology. One of the methods includes receiving instructions to execute two or more blockchain transactions on a piece of data, where all blockchain transactions of the two or more blockchain transactions modify a value of the piece of data, and for each blockchain transaction from the two or more blockchain transactions, pre-executing a smart contract associated with the blockchain transaction to generate a special instruction indicating the blockchain transaction, where the special instruction is used to validate that a current value of the piece of data supports the blockchain transaction when executing the smart contract to write the blockchain transaction to a blockchain.

A distributed computer architecture with a settlement mechanism to enable traceability of credit tokenization, disbursement, and repayment. A distributed ledger platform tokenizes credit for a project by recording one or more cryptographic tokens representing the credit on a ledger. A centralized business logic platform receives and stores account information for plural participants and associates a subset of the participants as designated participants for a project. A user interface allows the designated participants to transfer the cryptographic tokens on the distributed ledger platform to other designated participants in a peer-to-peer multi-level manner. For example, a grant can be distributed amongst many parties by distribution of the tokens. After receipt of the tokens, the various participants can request sign-off and redemption of the tokens to receive value, such as fiat currency for the tokens. Each transaction can be tracked on the ledger to provide traceability of grant funds.

An electronic financial transaction system employing a cryptocurrency, the system includes: a user terminal for requesting an electronic financial transaction by a cryptocurrency registered by a user; and an exchange server which, upon a request from the user terminal, analyzes an amount of the cryptocurrency corresponding to a target price of the electronic financial transaction according to a real-time market price of the cryptocurrency registered by the user, and makes a payment of the electronic financial transaction by that said amount of the cryptocurrency. According to the present invention, a user can make an electronic financial transaction such as purchasing a product or a service by a holding cryptocurrency or exchanging the holding cryptocurrency for cyber money by applying a real-time market price without exchanging a cryptocurrency holding for investment for a fiat currency.

Disclosed is a system for facilitating provisioning of social networking data to a mobile device. Further, the system may include a communication device configured for receiving at least one location information corresponding to a tour, receiving at least one selection corresponding to a plurality of filtering icons corresponding to a filtered social networking data, and transmitting a travel plan to the mobile device. Further, the system may include a processing device configured for filtering social networking data based on the at least one location information to generate the filtered social networking data, and generating the travel plan based on the at least one selection.

Techniques for routing to content within a mesh network based on a blockchain are provided. An electronic device can receive data from a mesh network to establish the device as a node on the mesh network. The established node can generate a cryptocurrency wallet that can be loaded with an amount of cryptocurrency. A blockchain can store searchable transactions related to content stored within the mesh network. The established node can search the blockchain to locate content and can transmit a request for certain content. The established node may issue a payment to a node hosting the requested content and/or to any intermediate nodes facilitating the established node's access to the content.

Systems and methods for distributed ledger-based intraday trading are disclosed. In one embodiment, a method may include: receiving a digital representation of an amount of collateral for a cash borrower; receiving a digital representation of an amount of cash for a cash provider; receiving agreement from the cash borrower and the cash provider to terms of an intraday trade comprising a duration of the intraday trade, a collateral trade amount of the collateral, and a cash trade amount of cash; a smart contract executing the intraday trade by providing the trade amount of the digital collateral to the cash provider and the cash trade amount of the digital cash to the cash borrower; and the smart contract returning the trade amount of the digital collateral to the cash borrower and the cash trade amount of the digital cash to the cash provider at the completion of the intraday trade.

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.
