Confidential Vault & zkStorage

Confidential Vault & zkStorage

Overview

The Confidential Vault & zkStorage is zkShine’s off-chain storage layer for sensitive information. It uses end-to-end encryption, zero-knowledge access proofs, and Solana-linked authentication to ensure data is verifiable yet invisible.

It enables a new class of decentralized identity and compliance solutions such as zkKYC, zkSoul, and zkReputation, where users can prove credentials or reputation scores without disclosing private information.

Core Capabilities

• End-to-End Encryption All stored data is encrypted with AES-256 and secured by user-owned cryptographic keys. No central authority has access to decrypted content.

• Zero-Knowledge Access Proofs Data access requests must include a valid ZK proof of authorization. The system validates access rights without revealing the data itself.

• zkIdentity Integration The vault natively supports Solana-based identity modules like zkKYC and zkReputation. These proofs can be verified by smart contracts to confirm user legitimacy privately.

• Data Immutability & Auditability Hashes of stored data are recorded on Solana, ensuring tamper-resistance and integrity verification.
