Fig 1. In a traditional web2 application, the back-end is protected from bots by a Captcha.
Fig 2. In a web3 application, the back-end is the blockchain, which is open to everybody.
Fig 3. Attempting to naively adopt the web2 approach to a web3 application fails because the front-end is not the only door to the back-end so a proxy can easily be bypassed.
Fig 4. Our P!Guard service transforms the traditional Captcha response into a Solana digital signature certifying the request. The on-chain program then checks that this signature is valid.
