I want to share an amazing information about bitcoin transactions
The developers Rodolfo Novak, co-founder of CoinKite, and Elaine Ou, Bloomberg columnist, completed the first Bitcoin transaction via radio waves.
In what appears to be a one-of-a-kind transaction, two developers working in separate countries have successfully sent a payment in the Bitcoin Lighting network via radio waves.
Organized from Twitter last weekend, the transaction was sent by Rodolfo Novak, co-founder of CoinKite, the Bitcoin hardware startup, to the developer and Bloomberg columnist, Elaine Ou. The completed payment effectively moved real Bitcoin from Toronto, Canada, to San Francisco, California.
The idea is that while the Internet can be censored, it is not the only technology that can be used to send data from one part of the world to another.
Radio may be an option "in case China decides to censor Bitcoin or places like North Korea where there is no Internet at all," Ou said in an email to CoinDesk. The technological infrastructure of the satellites of the Blockstream startup that transmit Bitcoin to users around the world was created for similar reasons.
Still, there are limits to the concept. "It was a fun demonstration, but obviously unrealistic because we coordinated everything online before sending the radio signals," Ou acknowledged.
The equipment is currently the difficult part: you need a radio that supports certain frequencies (14MHz). The most economical way is with a software-defined radio, which costs approximately USD $ 200 for something that can transmit low-power signals, or thousands of signals for a high-power transmitter.
