Bitcoin Sent Offline from Toronto to Michigan Through Shortwave Radio

The protocol used is identified as JS8Call which enables users to connect a shortwave radio to a computer.

Although the crypto winter seems to have prolonged into 2019, it has not stopped various inventions and developments to take place. In January, a cryptocurrency enthusiast in an unknown location in Eastern Europe paid with bitcoin (via lightning network) to broadcast strange messages from blockstream satellite high up in the sky.

In the most recent case, one user sent bitcoin to another user using shortwave radio. He used a free protocol for the shortwave communications to do the transaction. The protocol used is identified as JS8Call which enables users to connect a shortwave radio to a computer. Once they are connected, they can basically send and receive shortwave-transmitted text messages to other JS8Call users without any special license.

[…]The sender never prepared any signed transaction and then sent it to the recipient for them to broadcast it to the blockchain. On the contrary, he sent his recipient a private key that enabled the recipient to transfer the funds to his wallet using only that private key.[…]

Thanks for the tip, Jesse!

I must say, this is a fascinating concept and, I suppose, I’m not terribly surprised someone made it happen.  I’m pretty sure this shouldn’t have been done in the amateur radio 40 meter band.

The CBC: A truly “wireless” transfer of money

On The Morning Edition, CBC Kitchener-Waterloo was able to successfully transmit bitcoin over radio waves.

This makes what is believed to be the first known transmission of the digital currency by a public radio station.

A series of beeps were played over the air, and listeners were asked to use an app known as chirp.io to decipher a code produced by the sound.

Chris Skory of Rockland County, New York was the winning recipient, and unlocked 0.05 bitcoin worth about $40. The bitcoin was donated by Waterloo start-up Tinkercoin and a local bitcoin enthusiast.

“I did not think that I was going to get it at all,” said Skory. “I figured there was going to be some pretty stiff competition out there.”

Perhaps we should challenge VOA Radiogram‘s Kim Elliott to perform an international wireless transfer via shortwave?  🙂 Certainly be a great plot to attract listeners!
