You need to just peep in our blog to realize we take crypto security seriously. We often tend to discuss interesting and intriguing topics such as exchange hacks, wallet hacks, cryptojacking, and virtually all things crypto. Today we are not doing that. Or at least we’ll do our best not to. Today we are going to talk about a guy from New Zealand who managed to conduct a Bitcoin transaction without using the web and without plugging to the grid. Are you getting curious?
So how does the magic happen?
Yeah, you’ve read it right no internet, no electricity, Bitcoin transaction made possible. An extra creative dude from New Zealand used low-cost equipment to send Bitcoin more than 12km away.

His hardware included four goTennas and a cheap $30 Android phone. GoTennas are tiny devices that the adventurers among you are familiar with. They pair with smartphones via Bluetooth and can send data between each other with the help of the old-school radio waves. The problem is that goTennas work best in the outdoor, thus limiting off grid transactions to vast areas or the next Zombie Apocalypse.
Coinsure (that’s the dev) placed the antennas six kilometers in higher ground. He then put Samourai wallet in action to generate and verify his Bitcoin transaction. The goTenna messaging platform successfully recorded it as a message and transferred it to the smartphone of the dev’s girlfriend (sorry girls, that clever dude is not single).
As simple as it sounds, off-grid transactions have the potential to completely transform the way we think about communication and obviously, cryptocurrency. Just imagine that governments fail to properly regulate the industry and decide to ban digital assets worldwide. We can practically migrate to off-chain/grid/web/whatever transactions and run an independent network. As far-fetched as it sounds, we should explore this opportunity and develop and off-grid ecosystem that can handle large-scale transfers.
Sounds exciting, doesn’t it? Though I cannot help but ask “How do you secure goTennas?”.
