Project Dash N Go - the brainchild of Jeremy Mouse (Jeremy Maus), the creator of the machine for the sale of carbonated beverages with instant payment cryptocurrency Dash. This further development InstantSend technology allows you to pay for purchases in stores. InstantSend allows the transaction, without waiting for confirmation in blokcheyne and also eliminates the possibility of double-spending. The buyer simply scans the code with their smartphone product, payment takes place automatically.
Principle of operation
To confirm the transaction technology uses masternodov tier network: the network detects a transaction marked as «InstantSend», closes the transaction entry and transmits the message «confirmed tx» (confirmed transaction) to the network. This input can not be used for any other transaction.
As a result, the transaction is completed within 2 seconds. Next, the network transaction records blokcheyn in conventional manner.
This means that the first payment cryptocurrency on the operation speed can compete with payment by payment cards.
The project was selected by a vote, and was funded by the budget Dash system.
The first versions of the technology were to establish a secure Wi-Fi portal for small purchases, but the creation of a mobile application, which would be connected to this portal and distinguishes it from other Wi-Fi connections, it was considered inappropriate. Instead, the company created a mobile application that receives information from a standard Web server using a conventional data transfer protocol for the smartphone.
