    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.

          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.

            It’s a time and resource gate, not a way to prove that you’re a human.

            Also doesn’t Telegram require a phone number too?

            Sure, if you had unlimited gpus with unlimited electricity then it wouldn’t keep you from spinning up unlimited bots

              Bruh. No GPU needed. I build multiplatform apps daily on GitHub Actions. Dafuq you talking about?

            Bots can buy phone numbers, hell, they can solve most captchas better than humans.

            Telegram requires a phone number, so it clearly isn’t working.
