Bitcoin Goes Offline: Connecting Crypto Through Antennas and Satellites
18 Feb 2019
When Jack Dorsey described Bitcoin as the ‘native currency of the web”, little may he have thought about the possibility of it functioning without any internet at all. Experiments in making the network functional in the absence of an internet connection have been ongoing since 2017. The efforts have now begun bearing fruit as much of the world is now able to use Bitcoin by simply connecting antennas that relay data to ground stations, that in turn communicate with satellites. Welcome to the beginning of Bitcoin Going Offline.
According to a recent information made public by Outlier Ventures, in order for a censorship-resistant currency to be truly uncensorable, the mediums through which it reaches the end user needs to be outside the control of internet service providers. Blockstream’s satellites claim to broadcast the Bitcoin blockchain around the world, round the clock without any network interruptions. They currently cover North America, South America, Africa, Europe and Asia. Ground stations managed by Blockstream known as ‘teleports” relay data from regional transactions to geosynchronous satellites positioned 35,786 kilometres above the earth. Individuals can run a bitcoin node by simply using a USB based antenna to receive and send data from these teleports, as this comprehensive guide fully explains.
Satellites are not the only medium through which experimentation in token transfers have occurred. Recently, Coinkite’s founder Radolfo Novak made a cross-border Bitcoin transfer with the help of amateur, HAM radio. He transferred a string of characters representing a Bitcoin brainwallet all the way from Toronto, Canada to Michigan, USA.
Making Bitcoin’s blockchain independent of internet service providers increases the decentralisation of its network. Users in regions where there are strict regulations around the usage of tokens could rely on the service to send or receive capital without the intrusion of governments or banking entities. The utility of the network will be more useful in cases where a regional disaster wipes out local networks. The service can currently not only be used to transfer tokens but also encrypted messages which could be instrumental in nations where freedom of speech is restricted.
Future iterations of the product could also relay Bitcoin’s price in real time. Long story short – satellite enabled Bitcoin transactions could be instrumental in ensuring the network is accessible, regardless of a nation’s stance towards it, network presence in a region or ISP based censorship. Additionally, it could also pave ways for over 1.7 billion people around the world without a functional internet connection to begin engaging with the Bitcoin network. One small step for a handful of satellites, a giant leap for the network!
