## What Is QubitChain.io?

QubitChain.io is the world's first blockchain infrastructure built **natively on NIST-standardized Post-Quantum Cryptography (PQC)** from genesis block. It addresses the **Q-Day threat** — the inevitable moment when quantum computers break the RSA and ECC encryption underpinning Bitcoin, Ethereum, and all major digital asset infrastructure.

**Core technologies:**
- CRYSTALS-Kyber (ML-KEM, FIPS 203) — quantum-safe key encapsulation
- CRYSTALS-Dilithium (ML-DSA, FIPS 204) — quantum-resistant digital signatures
- SPHINCS+ (SLH-DSA, FIPS 205) — hash-based backup signatures
- QRNG — hardware quantum random number generation
- PoQE — Proof-of-Quantum-Entropy consensus mechanism

**Current status:** Pre-launch / Waitlist phase (2026)
