Enterprise-Grade Confidential AI Computation with Zero-Knowledge Verifiability
Privacy-Preserving Machine Learning on Solana
zkFractal is a privacy-first intelligence protocol combining Zero-Knowledge Proofs, Fractal encryption, and AI computation to enable verifiable machine learning on Solana β without exposing any data. The zkFractal SDK provides developers with a seamless framework to encrypt, compute, and verify AI operations securely. It transforms ordinary computation into cryptographically proven intelligence, ensuring privacy and trust at every step.
Compute privately. Prove publicly.
With zkFractal, intelligence evolves under encryption β bringing cryptographic assurance to the future of AI.
