Testnet Live — Mining Now

The First Blockchain Where Mining Solves Real Problems

NPChain miners solve NP-complete optimization problems instead of wasting energy on random hashes. Post-quantum cryptography. ASIC-resistant forever. Useful computation from day one.

Post-Quantum Native

Why NPChain?

Six innovations that no other blockchain has.

🧩

Useful Mining

Miners solve k-SAT, Subset-Sum, Graph Coloring, and Hamiltonian Path. These are real optimization problems that enterprises pay $50B/year to solve.

🛡

Post-Quantum Native

CRYSTALS-Dilithium signatures and Kyber key exchange from genesis. NIST-standardized. Every other chain needs a hard fork when quantum arrives.

⛓

ASIC-Resistant Forever

Problem type rotates every block across 4 NP-complete classes. You can't build an ASIC for all four. Mathematically guaranteed.

🗳

Democratic Governance

70% of all miners must participate in votes. 75% approval required. No silent takeovers. No whale-only governance. The network decides together.

🔐

Proven Privacy

Ring signatures (Monero-proven), Pedersen commitments, Dandelion++ IP privacy. All rebuilt with lattice math for quantum resistance. No ZK, no trusted setup.

🚀

NP-Native Layer 2

L2 batches encoded as SAT constraints, verified by L1 miners at zero additional cost. The only L2 architecture that can't be replicated on any other chain.

How It Works

Proof-of-NP-Witness: find a solution is hard, verify it is easy.

Previous block hash seeds SHAKE-256 PRNG

PRNG generates NP-complete problem instance

Problem type = hash mod 4:

   0: k-SAT   1: Subset-Sum

   2: Graph Coloring   3: Hamiltonian Path

Miner finds satisfying WITNESS

Every node verifies in O(n)

First valid witness wins block reward
