# Zero Knowledge Proof Storage System

The Quantum Safe Storage System is zero knowledge proof compliant. The storage system is made up of / split into 2 components: the actual storage devices use to store the data (ZDB's) and the Quantum Safe Storage engine.

The zero proof knowledge compliancy comes from the fact that all of the physical storage nodes (TFnodes) can prove that they store a valid part of the data that the quantum safe storage engine (QSSE) has stored on multiple independent devices. The QSSE can validate that all of the QSSE storage devices have a valid part of the original information. The storage devices however have no idea what the original stored data is as they only have a part (description) of the original data and have no access to the original data part or the complete original data objects.
