Prove unique-humaness

Prevent spam, bots, abuse and sybil attacks. Verify a unique human is performing an action only once.

Completely private

Personhood verification through the Orb can be completely private (zero PII). Further protected with ZKPs, it's impossible to know which actions an identity has performed.

Easy to integrate

Just a few lines of code and World ID protection can be added to any project. Both on-chain and off-chain.
