World Chain
A “humans first” L2 built on World ID (iris verification). Proof of Human acts as the city pass.
World Chain is the OP Stack L2 opened in October 2024 by the World (formerly Worldcoin) project. It is tied to World ID, which verifies that a user is a human with an iris-scanning device.
Its distinctive feature is priority blockspace for verified humans, so that people come before bots. This district’s weather follows the WLD token.
In an on-chain environment increasingly crowded by automated bots, World Chain pioneers a ‘humans-first’ fee market. Wallets verified through World ID receive a recurring allowance of free gas and priority blockspace ahead of automated scripts.
With tens of millions of users across emerging markets using its mobile mini-apps for remittances, stablecoin savings, and everyday payments, World Chain sustains high daily transaction counts driven by real retail activity rather than high-value institutional trades.
