Abstract

Version 1.0

ZKFile is a privacy-first data infrastructure built on Solana that enables users to store, share, and verify data without ever surrendering control. By combining client-side encryption, zero-knowledge proofs, and decentralized storage, ZKFile creates a sovereign data layer where users maintain complete ownership of their digital assets while enabling trustless verification and selective disclosure.

Unlike traditional cloud storage solutions that require users to trust centralized providers with plaintext data, ZKFile implements a zero-trust architecture where encryption happens entirely on the client side. The server never sees unencrypted data, keys, or sensitive metadata. This approach, combined with cryptographic proofs, enables a new paradigm: prove without revealing.
