Quantum provides an EVM‑compatible layer‑1 blockchain that is quantum‑secure from its inception, using NIST‑standard lattice‑based signatures (Falcon and ML‑DSA) to protect transactions, validator voting, and cross‑chain bridges. Its modular, crypto‑agile architecture allows developers to write Solidity contracts with familiar tools while ensuring long‑term resistance to both classical and quantum attacks, and it offers a multichain wallet layer for immediate post‑quantum protection on existing EVM networks.

Problem
Current blockchain networks rely on classical cryptographic signatures such as ECDSA, which can be broken by sufficiently powerful quantum computers using algorithms like Shor's. This creates a future risk of asset theft and loss of trust for digital assets and smart contracts that are not protected against quantum attacks.
Solution
Quantum delivers a purpose‑built, EVM‑compatible layer 1 blockchain that uses NIST‑standard post‑quantum lattice‑based signatures (Falcon and ML‑DSA) from genesis, eliminating the need for later migration. The platform embeds a modular cryptographic architecture that can evolve as new standards emerge, ensuring long‑term security against both classical and quantum adversaries. By treating post‑quantum signatures as the default authorization mechanism and integrating them into consensus, Quantum provides end‑to‑end protection for transactions, validator voting, and cross‑chain bridges. Developers can write Solidity contracts with familiar tooling while benefiting from quantum‑secure custody and verification. The system also offers a multichain wallet layer that enables post‑quantum‑only smart wallets on existing EVM chains, delivering immediate security improvements before full network migration.
Target Audience
Primary customers are blockchain developers, protocol teams, and wallet providers seeking quantum‑resistant security for smart contracts and digital asset custody, as well as enterprises planning long‑term blockchain deployments.
Features
- Native support for NIST‑certified post‑quantum algorithms (FIPS 203/204/205) including Falcon and ML‑DSA, baked into the protocol from block zero
- Full EVM compatibility allowing Solidity development, standard tooling (Hardhat, Foundry) and existing smart contract ecosystems
- Modular, crypto‑agile architecture that can swap or upgrade algorithms without disrupting the network
- PQ‑by‑default account authorization and consensus rules that treat post‑quantum signatures as first‑class protocol data
- Cross‑chain bridge (Entanglement) that requires post‑quantum verification for asset minting/unlocking, preserving security across ecosystems
- Multichain PQ wallet layer with MetaMask Snap and smart‑wallet contracts that accept only post‑quantum signatures, protecting assets on legacy chains
- Open‑source SDKs and APIs for JavaScript, Python, Rust, enabling rapid integration of quantum‑secure features into dApps
