# QubitChain.io
> The World's First Quantum-Powered Blockchain Infrastructure

QubitChain.io is the world's first blockchain infrastructure built natively on NIST-standardized Post-Quantum Cryptography (PQC) from genesis block. It integrates CRYSTALS-Kyber (ML-KEM), CRYSTALS-Dilithium (ML-DSA), SPHINCS+ (SLH-DSA), and hardware Quantum Random Number Generation (QRNG) to deliver a blockchain that is secure against both classical and quantum computing attacks.
