Bitcoin is already available for the Lightning Network via the radio network.
Last weekend, the deal was sent by Bitcoin hardware co-founder Rodolfo Novak, named BitKite, to Bloomberg's developer and columnist Elaine Ou. This transaction sent Bitcoin from Toronto, Canada to San Francisco, USA.
While most radio technologies are used to broadcast music or to make calls over the air, it actually has more features.
Two developers have shown that radio can be used to increase the flexibility of the Bitcoin network.
“Bitcoin is getting the amateur radio back again,” Ms. Ou said after successfully sending Bitcoin to Mr. Novak using “Ham Radio”.
In addition to fun to send Bitcoin via radio, there are some researchers who use it when they think it is necessary.
In fact, this idea belongs to Nick Szabo, the inventor of the smart contract. Ms. Ou and Mr. Szabo presented this idea at the Scaling Bitcoin Conference in San Francisco in 2017. At the time, some thought it could help Bitcoin create resistance to partition attacks, which researchers believe could be used to attack the network.
The idea is the internet. “If China or South Korea decides to review Bitcoin through their firewalls, there is no Internet at all.” Mr. Ou explained this in an email sent to Coindesk.
Previously, Blockstream reported on the launch of the satellite network API to send Bitcoin worldwide. This is a similar concept, but there are still limitations in concept.
"This is an interesting example. But it's not realistic because we coordinate everything online before sending a radio signal," Ms. Ou said.
“The hard part is equipment: you have to have a radio that supports these frequencies. The cheapest way is to find a programmable radio station worth $200.”
Novak's test is not the first time that cryptocurrencies are combined with radio waves. Five years ago, a Finnish software expert set up a radio station that sent blockchain information. The project is called Kryptoradio. This may allow the offline device to confirm the transaction and provide services to the customer, such as a vending machine. The project has never achieved commercial success, but it shows that there are radio and encryption methods that can be combined.
