Learn Concept: Layer 2 Blockchain for Biometric Authentication

By: Isha Das

World, previously recognized for its identity verification technology, has rebranded and launched a new initiative focusing on biometric authentication using Layer 2 blockchain technology. The newly introduced World Chain, built on Ethereum, exemplifies how Layer 2 solutions can provide scalable and secure platforms for large-scale applications requiring decentralized systems.

Layer 2 blockchains are secondary frameworks built atop a main blockchain to bolster scalability and speed, addressing mainchain inefficiencies like high transaction fees and sluggish processing times. In World Chain's case, this Ethereum-secured Layer 2 is fundamental to managing millions of biometric verifications securely.

This approach enhances user data protection, ensuring transactions and identity verifications remain decentralized and tamper-proof. It also allows for efficient user management of World ID credentials, supporting broader applications like World Pay and World Chat on the integrated World App. Such revolutionary uses of blockchain not only underscore the technology’s adaptability but also highlight the intersection of biometrics and decentralization—ushering in a new era of digital identity management.
