New York-based startup GoTenna will launch an Android app, txTenna, this summer that will allow users to initiate digital currency transactions without an internet connection, Coindesk reported.
andandby GThe oTenna device syncs with the phone to toggle the wallet apps settings,Can be offline and send digital currency.
Even in a disaster area, you can use digital currency. In the coindesk report, GoTenna engineer Meyers cites the Perdomo siblings recent work in Puerto Rico as an example, where GoTenna devices helped people reconnect after Hurricane Maria. As long as you have a way to charge your phone, you can surf the web and communicate.
Internet connections are not always reliable, and cryptocurrency users require a more private network for transactions. Generally speaking, the operation mode of GoTenna equipment is similar to the Bluetooth point-to-point transmission mode. As long as the user has a terminal device, private transmission can be realized.
GoTenna devices transmit information through a Mesh network (also known as a multi-hop network), and require two GoTenna devices to be less than one mile away. If an offline user initiates a transaction within range of another device, the transaction bounces around the network until it reaches a user with an internet connection.
The core of multi-hop network isHave every node in the network send and receive signals, the terminal devices in the network can automatically connect wirelessly to form a mesh structure, and each node in the network has an automatic routing function,Each node only communicates with neighboring nodes, and a resilient network can be built without a backbone network. As more nodes are interconnected and the number of possible paths increases, the total bandwidth will also increase.
The traditional wireless communication network must be designed and arranged in advance, and the transmission path is fixed, while the transmission path of the multi-hop network is dynamic. The Mesh network originated from the research on packet wireless networks funded by the Advanced Research Projects Agency of the US Department of Defense. The original motivation was to meet the needs of battlefield survival.
In addition, due to the short transmission distance, the required power is small, and the wireless signal interference between nodes is also small. High network capacity.
GoTenna devices cost $179 per pair, and GoTenna has sold more than 100,000 devices so far. In theory, the same txTenna code could also be implemented into the iOS wallet app. Currently, the company works with Samourai Wallet, but the txTenna cryptocurrency wallet will be an open-source project, Meyers explained: “It will be compatible with absolutely any software wallet, and any wallet provider will be able to initiate a transaction through it.”
But in fact, the connection of a large number of nodes can increase the bandwidth of the Mesh network, and the Mesh network has defects such as narrow usable range and large distance limitations.If you want to achieveDigital currency is not traded online, at least in the short term, GoTenna is not the best choice. Secondly, people may not need to conduct digital currency transactions in crowded music festivals or deep mountains with no signal coverage.
