NEBRA Launches Universal Proof Aggregator on World Chain

Zero-knowledge proof research firm NEBRA is launching its universal proof aggregator tool on digital identity giant World’s blockchain. The integration will slash the costs associated with running computationally heavy ZK proofs on World Chain.

About NEBRA’s Universal Proof Aggregation

NEBRA’s Universal Proof Aggregation is an Ethereum-based tool that condenses multiple, separate ZK-reliant systems like zkVM, zkRollups, and zk coprocessors into a compact proof to save on blockchain verification costs.

The Role of Zero-Knowledge Proofs

Zero-knowledge proofs, an idea that originated in academia and has taken root in the crypto ecosystem, are widely used across the digital asset sector to improve scalability and privacy. Essentially, it’s a cryptographic technique to verify data without revealing everything.

World Chain's Mission

World Chain, a blockchain supported by OpenAI CEO Sam Altman, aims to address challenges surrounding digital identity — especially the risks of misinformation, deepfakes, and spam in the AI Age. The network provides real humans, identified via a metal orb, with digital passports to traverse the web.

World employs zero-knowledge technology to keep personal information private and secure, having reportedly scanned the eyes of millions globally, partially incentivized by WLD token payouts.

Benefits of NEBRA UPA

By reducing the cost and complexity of proof verification, NEBRA is optimizing processes and creating new opportunities for developers and World App users. A World Foundation spokesperson stated, "NEBRA UPA’s built-in transparency strengthens World Chain’s dedication to censorship resistance and privacy as a fundamental right."

According to a press release, NEBRA UPA will cut World’s ZK computation costs by over 90% by bringing proofs on-chain.

NEBRA’s Background

NEBRA was part of World’s first “Community Grants Program” set up to develop tools advancing its “proof-of-personhood” technology. The startup previously raised $4.5 million in pre-seed and seed round funding, led by Nascent and Bankless Ventures, with participation from a16z’s Crypto Startup Accelerator.
