Worldchain

World Chain

Worldcoin's OP Stack L2, designed to put proof-of-personhood at the chain level for sybil-resistant apps.

Worldchain orbs verify a unique human via iris scan; the resulting World ID can gate L2 actions. Stablecoin yield surface is small today; the chain's value is more about identity primitive than DeFi liquidity depth.
