No, it is just a namespace, and you can predict addresses that you control but haven’t generated yet

Or send to one that nobody has the key for

Additionally, you can prove you have the key completely offline if you want, which can suffice for collateral or pose authorizations

Most of these features of Bitcoin have been abstracted away for user friendliness, but are still accessible

if you know you know, solved problems (ratified protocols and standards) since 2012 or so

I can never understand why signing authorizations offline never took off.

If I can physically see the inputs and outputs, it doesn’t take much to have a pretty good idea that it’s not bidirectonally compromising the cold wallet machine before sneakerneting them back and forth on a printed QR code.

I think armory wallet was the big thing for this? It’s been a while.

Meanwhile the best approach people commonly have today is a “hard wallet” that plugs into a usb port (yuck!)

		yeah its a lost art, and everyone’s/wallet’s default reliance on clearnet remote RPC basically kills all privacy I hope this doesnt become like email, where self hosting everything winds up blacklisting you in various ways
