How to send Bitcoins without connection to Internet or electrical network?

“I’m sure that in 20 years there will be a large volume of transactions in Bitcoins, or none at all.” -Satoshi Nakamoto.

On one occasion I heard in a documentary that read “The genius of the lamp has come out and nobody can stop it”, making reference to the creation of Bitcoin. And, personally, it is very encouraging to read and share news of how people who have understood the meaning of Bitcoin, add each day to this global project, contributing their knowledge and creativity to further strengthen the philosophy that motivated Satoshi Nakamoto to create Blockchain for Bitcoin, to prevent banks and governments (intermediaries) control our money.

Recently a developer from New Zealand posted on his social networks that he had made a Bitcoin transaction at a distance of 12.6 km without using a cell phone network or Internet connection. It is excellent news, for places that are difficult to access or without a connection to the web.

According to its publication, it occupied a set of cheap devices, how 4 goTenna mobile devices and an Android phone. goTenna are small devices that groups of travelers use to keep in touch in places where there is no cell network coverage. These devices can connect to smartphones via Bluetooth and send data on radio frequencies to other similar devices.

Then, using a smartphone, he generated a signed Bitcoin transaction in the form of a goTenna message in Samourai’s wallet. The goTenna service successfully sent two signed Bitcoin transactions to the smartphone of a friend of a developer who was also connected to the goTenna network. The first transaction was sent to 5.6 km, and the second, to 12.6 km.

All this may seem too simple and even primitive, but in some cases such networks can be very useful, for example, during natural disasters. As if that were not enough, all the devices used can be powered by solar energy, which means that in theory the entire system can exist without being connected to the network, however, it will always be necessary to synchronize with the chain of Bitcoin blocks.

The real breakthrough here is that this goTenna system is much simpler (and more accessible) than other Bitcoin shipping solutions created lately.

Last month, a group of developers published details of a similar concept that used solar power, battery packs and shortwave radios to perform transactions outside the network. This project was a presentation for the Call For Code challenge, which pitted developers against each other to create technology that can help in preparation and relief in times of natural disasters.

Despite this, we are currently more familiar with the use of our cell phones than shortwave radios, since they require more specialized knowledge than smartphones to operate them, and in some countries permits are needed for the use of these radios. That is, much more equipment than the four goTenna devices and a cheap smartphone.

Undoubtedly, this experiment marks the foundations for the development of devices that allow the transfer of digital values ​​without the immediate consensus of the network.

Never forget:

“The essence of Bitcoin, is to give sovereignty and freedom to individuals over their money to control their wealth.”
