The txTenna application allows people to send transactions in bitcoins even when disconnected from the Internet. It works thanks to goTenna Mesh, a small radio transmitter and receiver that allows smartphones to communicate directly with each other without using third-party mobile networks. Mesh networks are a type of computer network where nodes communicate directly with each other, as equals, to send data over the network in the most direct and efficient way. In terms of blockchain applications, the Lightning network is presented as an example of a mesh network. goTenna markets its goTenna Mesh product, which costs $ 249 per pair, as an emergency communication system for mobile outages or for hikers in remote areas or elsewhere. It was founded by brothers Jorge and Daniela Perdomo after Hurricane Sandy hit the United States in 2012 and left the mobile service inactive. In the goTenna system, users can connect a goTenna Mesh device to their mobile phone and then connect to other goTenna Mesh users to exchange text messages. The maximum range between the goTenna Mesh nodes is about 6 km. Samourai mobile wallet users, who connect to the txTenna open source application, will be able to send bitcoin transactions from their mobile phone to other nearby goTenna mesh nodes. The transaction can then be relayed by other nodes in the network until it reaches a node connected to the Internet. At this point, the transaction can be transmitted to the Bitcoin network. For some members of the Bitcoin community, mesh networks are an important way to access the Bitcoin network that does not rely on traditional Internet and telecommunication infrastructure. The argument is that this increases the resistance to censorship and reduces the risk of interference by governments or companies with the Bitcoin network.
