Welcome to Quranium

Welcome to the comprehensive documentation of Quranium Chain, an innovative quantum-secure blockchain architecture that powers with Proof of Stake (PoS) with quantum-secure SLHDSA at core level.

Quranium is the first blockchain to make blockchain quantum-proof at the core level.

This documentation provides detailed insights into the technical architecture, implementation guidelines, and future development roadmap.

Key Features

• Smart Contracts: Supports Solidity & EVM compatible smart contracts

• Quantum Security:Utilises SLHDSA for quantum-proof digital signatures.

Quantum Security

Quranium Chain implements cutting-edge post-quantum cryptography using SPHINCS+ signature schemes, making it resistant to potential quantum computer attacks.

SPHINCS+ Implementation

• Stateless Hash-Based Signatures: Utilizes SLHDSA for quantum-resistant digital signatures

• Parameter Sets: Implements SLHDSA -256f for optimal balance between security and performance

• Key Generation: Secure key generation process with quantum entropy sources

        "hash_function": "SHA-256",
        "security_level": "256-bit"
    }
}

Quantum Security Features

• Post-Quantum Secure: Protected against both classical and quantum computer attacks

• Forward Security: Maintains integrity even if quantum computers become available

• Compatibility: Seamless integration with existing blockchain operations

The implementation of SPHINCS+ makes Quranium Chain one of the first blockchain platforms to achieve quantum security, future-proofing the network against emerging quantum threats. With NIST Approval and Migration to SLHDSA, Quranium becomes the battle-tested quantum-secure blockchain.

Possible Migration Overview

• Gradual Transition: A phased approach to ensure network stability during the upgrade

• Backward Compatibility: Support for both SPHINCS+ and SLHDSA during the transition period

• Enhanced Performance: SLHDSA offers improved signature generation and verification times

SLHDSA migration timeline and implementation details. The migration process will be carefully coordinated with the community to ensure minimal disruption to network operations.

Technical Considerations for future possible migration

The migration to SLHDSA will introduce several improvements:

• Reduced Signature Size: Approximately 50% or smaller than SPHINCS+

• Faster Verification: Up to 2x or higher improvement in verification speed

• Enhanced Security Margins: Improved resistance against quantum attacks

All node operators will need to upgrade their software to support SLHDSA before the final migration deadline. Detailed upgrade instructions will be provided in future documentation updates.
