Why Passport is a gamechanger for both web3 projects and users
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.
