**Worldcoin Unveils World Chain: A New Ethereum Layer 2 Blockchain**

Worldcoin, founded by Sam Altman, has launched World Chain, an Ethereum layer 2 blockchain, rebranding itself as "World." This new network aims to enhance efficiency and introduce new features for its 15 million verified users.

Key points:

- Users with a "World ID" can now access the network by scanning their iris.

- World Chain prioritizes verified human users, providing them with block space and free gas allowances.

- The blockchain will support top apps like Optimism, Uniswap, Zerion, and Alchemy.

World also introduced a new, more powerful version of its biometric Orb device and announced partnerships with social media apps like FaceTime, WhatsApp, and Zoom. Despite the launch, Worldcoin's WLD token saw a slight dip, falling 2.1% according to CoinGecko.
