We are building fun and more secure CATPCHAs for web3. In the context of this work, we can build a Farcaster (Frame) Faucet, protected by our CAPTCHAs, where users slowly accumulate a "proof-of-liveness" score. This proof can then be used in other services in the ecosystem. For example, we can issue a verifiable credential that a specific user has accumulated a specific score on-chain.

We note that this is very different than the identity field as we specifically focus purely on the "liveness" aspect rather than actually knowing the identity of a person.
