Private messages, relaying for 3rd parties and encryption are prohibited in Ham Radio, so thinking about (international) transactions over ham radio is just plain bullshit. This is the first thing every licensed Ham learns.

What you're looking at here are licensed commercial radio services.

Bitcoin transaction is basically a broadcast, which you can analyze freely. No decryption, just encoding and signing.

Broadcasts are prohibited in ham radio.

I don't think this is allowed under USA Amateur radio rules.

> §97.113 Prohibited transmissions.

> (b) An amateur station shall not engage in any form of broadcasting, nor may an amateur station transmit one-way communications except as specifically provided in these rules; nor shall an amateur station engage in any activity related to program production or news gathering for broadcasting purposes, except that communications directly related to the immediate safety of human life or the protection of property may be provided by amateur stations to broadcasters for dissemination to the public where no other means of communication is reasonably available before or at the time of the event.

Also a lot of messages in the bitcoin blockchain are encrypted

That's not against the rules. The Amateur Radio Relay League (ARRL) gets it's name for doing this. It's illegal to hide these messages or to use them for a commercial purpose. Original HAMs used to do radio telegrams (radiograms) for the public [0].

>>>Private messages (...) are prohibited in Ham Radio

Wait what? Isn't any message either broadcast or private?
