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

[sciurus]

Broadcasts are prohibited in ham radio.

For the US, see https://www.ecfr.gov/cgi-bin/text-idx?SID=1a361a6eb3d1594e6a...

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

> Broadcasts are also prohibited in ham radio.

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

[sciurus]

No, it's either one-way or two-way. One-way is usually prohibited except in a few case, two-way is usually fine unless it violates one of the prohibitions like encryption. Your two-way communications using ham radio are public, not private.

[jkoberg]

"Broadcast" is defined as "transmissions for the consumption by the general public", at least in the US. Not one-way vs two-way.

[dunham]

It seems broadcasting is prohibited, but broadcasting is defined as:

> (10) Broadcasting. Transmissions intended for reception by the general public, either direct or relayed.

Edit: quote is take from "Definitions" section of sciurus link.

A two-way conversation that involves short periods of what's technically "broadcasting" is very different from "tune in at 10pm to hear me talk for an hour".

Also a lot of messages in the bitcoin blockchain are encrypted
