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.
Accessibility is very important to me as a blind user, and this helps tremendously.
Anything you use to autotranscribe images or are image uploads without alt text a nightmare?
Images w/o alt text suck
Ah bummer… I’ll do better!
Oh, neat. I was unfamiliar with PoW. Thanks!
Pow does not limit spam in bitcoin. Fees do. Pow is used as a decentralized election mecanism to distribute the block production.
I know what it is. It is not a barrier to entry though.
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.
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?
You're in the wrong thread.
I'm really not. Did you want to try making a coherent point again? Or are you all tapped out?
Yes. Please explain again how compute == human
It doesn't... No one was claiming that...
Are you lost?
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?
how do you produce unique hashes with the correctly sized nonce?
Dafuq are you talking about ? Telegram does need phone numbers for sign up
Check that
Of course it does.
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.
