As Internet connections are not always available, reliable or private, cryptocurrency users need alternative methods to connect to the network. You must be able to spend your bitcoin even in disaster areas. Blockstream Satellite and goTenna are technologies to help facilitate the sending of transactions in bitcoins to people without a direct Internet connection. Blockstream Satellite is a satellite network deployed so that people around the world can download a full Bitcoin node, the most secure software on the Bitcoin network, even without an Internet connection. That is, they have a satellite receiver with the specific Blockstream Satellite software installed.
goTenna is an exploration technology that allows users to connect to others without using the Internet. Instead, they formed their own “mesh network” for sending messages. The limitation is that a user must connect to a nearby person, within a one-kilometer radius, to send a transaction. The goTenna device also connects to a bitcoin wallet on an Android phone where users can insert bitcoin and then use it to send bitcoin transactions without an Internet connection – as long as they can connect to another goTenna user with an Internet connection. This means that users will be able to receive blockchain data via satellite and send signed bitcoin transactions via the goTenna Mesh network without a direct connection to the Internet. If your local provider is censoring you or if your connection is down for any reason, perhaps because of a natural disaster, you can still access the Internet. This integration is part of a broader effort to make it easier for users to send offline transactions. The need for this technology might not be in Montreal, but in other parts of the world. This could be useful there instead of centralized Internet providers.
