A blockchain-based data processing system may comprise: a transaction-side blockchain node and a server-side blockchain node on a blockchain network maintaining a blockchain. The transaction-side blockchain node may be configured to: create a transaction data structure based on an Unspent Transaction Output (UTXO) model, consolidate transaction data of a transaction according to the transaction data structure to generate shared transaction data, execute a smart contract of the transaction-side blockchain node to automatically determine a to-be-settled commission amount, update the shared transaction data according to the to-be-settled commission amount, collect the updated shared transaction data according to a preset condition, and send a to-be-settled transaction processing request comprising the updated shared transaction data to the server-side blockchain node. The server-side blockchain node may be configured to: receive the to-be-settled transaction processing request, and calculate a sum of the to-be-settled commission amount in the updated shared transaction data.

The invention pertains to a computer server configured for digitization of a multi-party market order agreement and to communicate with a distributed ledger computer system that includes multiple computing nodes, each computing node configured to store at least a partial copy of a blockchain of the distributed ledger computer system. The computer server may comprise a give-up multi-party agreement (MA) platform for digitizing, reconciling and calculating a financial transaction on the MA platform. The server may include executing account references for a derivatives order. The server may include clearing account references for the derivatives order. Further, the server may reconciliate trading limits for the derivatives order. The server may undertake an interest computation. Finally, the server may reconciliate fees for the derivatives order, product exclusions and the legal language of the legal agreement MA.

A blockchain-based method is described which is related to transferring electronic currency from a payer to a payee. In some embodiments, a first process, a second process and a third process are performed. The first process includes receiving a processing request for a target transaction from a terminal of a payer, and transferring the processing request to a first blockchain node among a plurality of blockchain nodes. When a verification result indicates that the target transaction is valid, the method proceeds to performing the second and third processes. The second process includes transferring electronic currency from an electronic wallet of the payer to an electronic wallet of the payee. The third process includes recording data for the target transaction in a new block, and spreading the new block over the blockchain network. In some embodiments, the second process and the third process are performed in parallel.

The disclosure relates to a method for requesting and granting priority between a host vehicle and other vehicles, and to a system which implements the method. The host vehicle, through the use of on-board vehicle sensors, detects and identifies an impeding vehicle which interferes with the host vehicle's path. The host vehicle transmits a priority request to the impeding vehicle. The priority request includes a remuneration offer. The impeding vehicle evaluates the priority request, including the sufficiency of the host vehicle's remuneration offer, and grants or denies the host vehicle's priority request. If granted, the impeding vehicle modifies its path to be less impeding to the host vehicle, for example by assuming a cooperative path that lets the host vehicle pass the impeding vehicle.

Methods and systems are disclosed for transactions with a private digital currency. The private e-currency may be backed by a financial institution, managed using a blockchain, and only available for transactions with members of a network associated with the financial institution. The members may include mobile wallets, merchants and ATM's. A mobile wallet may register with the network and receive an amount of the private e-currency from the financial institution. The mobile wallet may establish a connection with a payment recipient such as another wallet, an ATM or a merchant, and receive a payee address. The mobile wallet may send a transaction request to the blockchain for payment to the payee address of a payment amount of the private e-currency, so that the payment recipient can, using a blockchain, confirm or deny the transaction request.

A computer-implemented method for performing by a node of a network of nodes for maintaining at least part of a distributed ledger maintained by the network of nodes is described. The method comprises maintaining at least part of the distributed ledger. The at least part of the distributed ledger is configured to store records and associated verification data for the records. The verification data for a record identifies: (i) a sequence of nodes in the network which received the intended record during a verification procedure; and (ii) the respective event state assigned by each node of the sequence of nodes to the intended record during the verification procedure.

Taught is a system for the exchange and value management of cryptocurrencies using servers/VPNs to enhance the knowledge of a user in order to manage/exchange cryptocurrencies, purchase merchandise with cryptocurrencies or invest with cryptocurrencies. These activities are done via smart devices or IOT (internet of things) devices with the ability to see a screen and manipulate data to best serve ones needs in the management of and purchasing with cryptocurrencies or exchanged cryptocurrencies.

A system and method for transaction bitcoin is described. Bitcoin can be sent to an email address. No miner's fee is paid by a host computer system. Hot wallet functionality is provided that transfers values of some Bitcoin addresses to a vault for purposes of security. A private key of a Bitcoin address of the vault is split and distributed to keep the vault secure. Instant exchange allows for merchants and customers to lock in a local currency price. A vault has multiple email addresses to authorize a transfer of bitcoin out of the vault. User can opt to have private keys stored in locations that are under their control. A tip button rewards content creators for their efforts. A bitcoin exchange allows for users to set prices that they are willing to sell or buy bitcoin and execute such trades.

An apparatus includes an acquisition processing circuit and an identification processing circuit. The acquisition processing circuit acquires first exchange information, second exchange information, and fee information, the first exchange information allowing identification of a first exchange where a first user has an account, among exchanges that deal with cryptocurrencies, the second exchange information allowing identification of, among the exchanges, second exchanges where a second user has accounts, the fee information including information about remittance fees that are required for cryptocurrency remittances among the exchanges. The identification processing circuit identifies, among the second exchanges, a second exchange that requires a lowest remittance fee for remittance with the first exchange, based on the first exchange information, the second exchange information, and the fee information.

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.
