Empeiria Documentation

Empeiria is the first End-to-End Verifiable Data Infrastructure (EVDI) that combines Self-Sovereign Identity (SSI), Decentralized Identifiers (DIDs), and Zero-Knowledge-Proofs (ZKPs) to ensure trusted and verifiable data management. It enhances AI model efficiency through structured data verification while enabling organizations and individuals to maintain complete control over their digital identity with seamless one-click deployment and passwordless authentication
