PoC: Migrate to Prosopo

[Bullrich]

Me and @rzadp have been in touch wit the guys from Prosopo and they have a decentralized captcha system currently on the Rococo parachain: prosopo/captcha.

It would be interested to create a Proof of Concept to see how it works and to consider replacing google captcha for this alternative.

The implementation of Google captcha in the client can be found in: CaptchaV2.svelte

For the server we have this class: Recaptcha.ts

Thanks for writing this up @Bullrich! We'll start on an implementation early next week.

Thanks

It would be interesting to have the ability to configure either standard recaptcha provided by Google or Prosopo. As long as we don't remove existing "production" captcha solution. I'm all for migrating to decentralized captcha, especially if it is built on Polkadot !

Hi @PierreBesson, no problem. We'll add a feature flag in to enable Google or Prosopo.

I'm thinking this is excessive. Procaptcha either will work and we will use it, or it won't prove itself reliable and we'll revert the changes. Supporting two systems at the same time doesn't have a practical application IMO.
