QuantumCoin

Quantum Coin is a community-driven blockchain project building a quantum-resistant Layer-1 network with smart contract support. Its platform uses NIST-standardized post-quantum cryptography, including ML-DSA and SLH-DSA for digital signatures and ML-KEM for secure communication between nodes. The project describes this hybrid approach as protection against threats posed by future quantum computers. Its deposit-weighted proof-of-stake consensus uses a Byzantine fault-tolerant protocol designed to provide deterministic block finality.

The ecosystem includes Q, the network’s native coin, self-custody wallets for Android, iOS, Windows, and Mac, and resources for acquiring Q through listed exchanges and Banxa. Users can explore the blockchain through a block explorer, while developers have access to smart contract tools, Solidity documentation, an SDK, a browser-based builder, and a JSON-RPC API. The project also provides guidance for running validator nodes, staking, and participating in network operations, alongside technical whitepapers and a roadmap. Quantum Coin states that its initiatives are aspirational, community-led, and not guaranteed to be delivered.
