Signal’s mission and sole focus is private communication. For years, Signal has kept your messages private, your profile information (like your name and profile photo) private, your contacts private, and your groups private – among much else. Now we’re taking that one step further, by making your...
For each account you register, you have to do 30 seconds worth of work. So to register one account, you do 30 seconds worth of work. To register 100 accounts, you do 100*30 or 3000 seconds (50 minutes) worth of work. Registering tens of thousands of accounts then becomes unfeasible.
Exactly! ANYTHING THAT CAN COMPUTE CAN DO IT. Few things have a uniquely identifying piece of information with other levels that are barriers to entry…like a phone number. The idea is to STOP bots from signing up to Signal.
If preventing Jimmy Bumfuck from spinning up a couple sock puppets is your fear, yeah, PoW systems don’t help. But those are rarely the problem.
For a phishing scam or astroturf operation to be worth it, you need tens of thousands of accounts all running the same script. Those get filtered hard by PoW systems.
Phone validation works just as well, and stops Jimmy Bumfuck from making sock accounts. But now every user must be stapled to a phone number. Maybe that’s a worthwhile trade to you, but it sure doesn’t seem to be to everyone replying to you.
PoW…Prisoner of war?
Proof of work. Example, bitcoin
How does this prove anything if using an emulator to bulk register bot accounts? Also, Signal Desktop is a thing.

And how can a VM or emulator NOT do this?
Anything that can compute can do it. The important part is that it has an associated non-insignificant cost.

Are you missing the point maybe?
It stops bot FARMS from being feasible.
