The Unique Humanity Score

We don't believe in one-size-fits-all solutions for proving your Unique Humanity. So we give users the choice to prove their identity.

Users can choose to add credentials from BrightID, Civic, Gitcoin, Coinbase, and more to increase their Unique Humanity Score.

Multiple Scoring Algorithms

Our built-in credentials scorer and battle-tested default score makes Sybil defense easy and effective. But if you don’t want to opt for Gitcoin's battle-tested defaults, and want to design your own trustworthiness scoring algorithm, you can choose to create a Scorer that meets your unique requirements.

Onchain & offchain identity verification

Our Developer API evaluates people’s unique humanity offchain, but if you want to bake in scoring into a smart contract, you can choose to do that. That’s why we now enable our Passport holders to push their stamps onchain.

"Proof of Humanity and other proof-of-personhood systems let users prove that they are unique humans, which is useful in many applications including airdrops and governance. Each of these applications are useful individually. But what makes them truly powerful is how well they compose with each other.

The network effects of these different services [through a meta-aggregator like Passport] combine to create an ecosystem that provides some very powerful options for users and applications.

An Ethereum-based Twitter alternative (eg. Farcaster) could use POAPs and other proofs of on-chain activity to create a "verification" feature that does not require conventional KYC, allowing anons to participate.  

Such platforms could create rooms that are gated to members of a particular community - or hybrid approaches where only community members can speak but anyone can listen."
