      A PoW could limit bots too. Require say 30 seconds of work before your registration submits. For regular users that isnt to bad. For bots its a PITA to get tons of accounts

      Edit: tor uses PoW as DDOS protection and its helped massively

          That will also keep away bots.

          You can only sign up if you’ve taken at least one Prisoner of War. Bots can’t take prisoners of war for obvious reasons.

          Kinda like how Aztec boys came into age in their society.

              It was the original purpose of the bitcoin algorithm to limit spam.

              If you have to do a lot of maths that takes your computer (for example) 30 seconds, that means it costs 30 seconds of compute to create an account. Nothing to an average user, for a spammer that wants thousands of accounts it gets expensive.

              Several captcha[0] libraries already use this and it’s great for accessibility (normal captchas are terrible for it)

              [0] I know, it’s not technically a captcha.

                Pow does not limit spam in bitcoin. Fees do. Pow is used as a decentralized election mecanism to distribute the block production.

                  He explained why it is, so can you elaborate on why it’s not?

                    Because it’s not. I can spin any number of emulators or VMs that do any amount of work with a simple script, but that’s all it does. How does it prove I’m anything but a scripted, virtual instance of a person with a device?

                    There’s a reason why Telegram is flooded with bots, Signal as of now has not been.

              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.

                  Anything that can compute can do it. The important part is that it has an associated non-insignificant cost.

                    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.

                    Are you missing the point maybe?
