# Introduction

**Quantropy** is the systematic injection of non-deterministic entropy into blockchain.

In plain terms: Quantropy is a protocol and infrastructure layer that supplies *verifiable, real-time quantum randomness*—harvested from physical subatomic particle collapse—instead of software-generated pseudo-randomness. It is a **Decentralized Physical Infrastructure Network (DePIN)** that anchors this entropy on-chain (Solana) and exposes it via a low-latency API backed by a multi-vendor quantum processor fleet (IBM, IonQ, Rigetti).

* **Primary tech stack:** Solana (settlement), multi-vendor QPU fleet, REST/gRPC API.
* **Core value:** Moving from digital simulation to physical reality—replacing vulnerable software simulations with absolute sub-atomic physics.

Every entropy request returns high-fidelity random bytes plus a **Quantum Job ID** and **Solana transaction**, so you get both the randomness and the proof. Use it for cryptographic nonces, fair lotteries, AI agent seeds, oracles, and any use case where verifiable, non-deterministic randomness matters.
