The quantum-safe blockchain
Quantaureum secures every account and every signature with NIST-standard post-quantum cryptography. Built from scratch and open source, the project is currently in testnet phase.
A protocol designed for the quantum era
Quantaureum is built from scratch around post-quantum cryptography — not patched on top of legacy schemes.
Post-quantum, by default
Every signature uses ML-DSA-65 (FIPS 204, derived from CRYSTALS-Dilithium) and every key exchange uses ML-KEM-768 (FIPS 203, derived from CRYSTALS-Kyber). There is no classical fallback left to attack. Your account stays secure when large quantum computers arrive.
2 NIST standards
FIPS 203 + FIPS 204 at the protocol core
QPOS consensus
Proof-of-stake with GM-QTD threshold signatures: blocks finalize only when the validator committee signs — no single key can forge finality.
QVM smart contracts
A purpose-built virtual machine with the QASM contract language and a JIT engine, designed for parallel execution from day one.
Built to scale
Sharding, erasure-coded data availability and rollup support are design and roadmap items, not shipped feature claims. See qau/ROADMAP.md for the authoritative status.
Open and independent
Written from zero by an independent developer and released as open source. Everything is public on GitHub.
Seven layers, one stack
From post-quantum keys at the bottom to the public API at the top, every layer of Quantaureum was written from scratch by one independent developer.
