The privacy problem in blockchain and why AFHE matters

Blockchain's public nature creates a fundamental privacy paradox. Every transaction is permanently recorded, replicated, indexed, and analyzed. What appears anonymous today can be traced tomorrow through a single information leak.

The consequences are profound: in 2023, hackers stole 7 million people's genetic data from 23andMe. Those people can change their passwords—they cannot change their DNA. Some data is so sensitive that its exposure isn't just inconvenient; it's irreversible.

As AI becomes ubiquitous, this problem intensifies. Using AI services means surrendering your prompts, your data, your queries to third parties. There has been no way to compute on encrypted information—until now.

AFHE (Aura Fully Homomorphic Encryption) solves this by enabling computation on encrypted data without ever decrypting it. This isn't theoretical—it's working technology delivering 100x faster performance than existing FHE solutions.
