# Quranium

Quranium Chain is a **post-quantum secure EVM-compatible blockchain** designed to protect against future threats from quantum computing. Below is a detailed breakdown of its supported features and key considerations:

***

### **1. Native Token Transfers (QRN)**

#### **What It Means**

Users can send and receive **QRN** , the native token of the Quranium Chain, just like ETH on Ethereum or MATIC on Polygon.

#### **How It Works**

* QRN is used for:
  * **Gas fees**: Paying transaction fees.
  * **Staking/delegation**: Participating in network security.
  * **Value transfer**: Sending funds between accounts.
* Transactions are signed using **SLHDSA** , a **post-quantum digital signature algorithm** .

#### **Why It Matters**

Unlike traditional blockchains that use ECDSA signatures (vulnerable to quantum attacks), Quranium ensures long-term security even if quantum computers become viable.

### **2. SLHDSA Signature Transactions**

#### **What Is SLHDSA?**

* **SLHDSA** stands for **Stateless Hash-Based Digital Signature Algorithm** .
* It is a **NIST-standardized post-quantum cryptographic scheme** , part of the SPHINCS+ family.
* Unlike ECDSA (used by Ethereum), it does not rely on elliptic curves but on hash functions, making it resistant to quantum attacks.

#### **How It’s Used**

* Every transaction on Quranium Chain is signed with an **SLHDSA private key** .
* The corresponding public key is used to derive the wallet address (similar to Ethereum-style Keccak-based addresses).
* This ensures all user actions (e.g., sending tokens, interacting with smart contracts) are **quantum-safe** .

#### **Implications**

* Wallets must support **SLHDSA signing logic** (like QSafe Wallet).
* Standard Ethereum wallets (e.g., MetaMask) cannot sign transactions unless they integrate post-quantum libraries.
