Bitcoin Sent Offline from Toronto to Michigan Through Shortwave Radio<\/h3>\n

The protocol used is identified as JS8Call which enables users to connect a shortwave radio to a computer.<\/strong><\/p>\n

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.<\/p>\n

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.<\/p>\n

[…]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.[…]<\/p><\/blockquote>\n
