Naoris Protocol launched the first natively post-quantum Layer 1 blockchain on April 2, 2026, using NIST’s highest-tier cryptographic algorithm to protect transactions from quantum computing attacks that researchers now say could arrive by 2029.
A post-quantum blockchain is a network built from the ground up with cryptographic algorithms designed to resist attacks from quantum computers, which can break the encryption protecting most existing blockchains.
Key takeaways
- Naoris Protocol’s mainnet uses CRYSTALS-Dilithium (ML-DSA-87), a NIST Security Level 5 algorithm, making it the first blockchain with native quantum resistance at the highest certification tier.
- Google recently accelerated its post-quantum migration deadline to 2029, and researchers cut the quantum resources needed to break RSA-2048 encryption by a factor of 20.
- The testnet processed over 106 million transactions and blocked 603 million security threats before mainnet launch.
- Investor Tim Draper backs the project, and the SEC cited Naoris in a research submission on post-quantum financial infrastructure.

Why quantum threats to blockchain are no longer theoretical
Google’s quantum computing division revised its post-quantum cryptography migration deadline to 2029, years ahead of U.S. federal targets set for 2035. More alarming for the crypto industry: researchers reduced the estimated quantum resources needed to crack 2048-bit RSA encryption by a factor of 20. That means the “Q-Day” scenario where quantum computers can break standard blockchain encryption is moving from distant possibility to near-term operational risk.
Bitcoin, Ethereum, and most existing blockchains rely on elliptic curve cryptography (ECC) for transaction signing. A sufficiently powerful quantum computer running Shor’s algorithm could derive private keys from public keys, potentially exposing billions in assets. The EU has responded with a roadmap requiring national quantum strategies by 2026 and full critical infrastructure transition by 2035.
Naoris Protocol’s answer is to skip the retrofit and build quantum resistance into the foundation. The mainnet runs CRYSTALS-Dilithium at NIST’s ML-DSA-87 standard, the highest security level the agency certifies. Every transaction, validator signature, and smart contract interaction is protected from day one.
How the Naoris mainnet works
Naoris positions itself as a “Sub-Zero Layer” that operates beneath traditional L0 through L3 blockchain layers. The architecture is designed to secure not just its own transactions but also external infrastructure: decentralized exchanges, cross-chain bridges, validator nodes, enterprise cloud systems, and IoT networks.
The network uses a consensus mechanism called dPoSec (Decentralized Proof-of-Security), which rewards validator nodes for detecting anomalies and validating device integrity in real time. Validator nodes themselves are secured with ML-DSA-87 signatures, closing a common attack vector where validators could be compromised.
Smart contracts on the network maintain EVM compatibility. Developers can write in Solidity using standard tools without needing to configure quantum security separately. The protocol enforces an “irreversible security transition”: once a user upgrades to post-quantum keys, the network permanently blocks any attempt to use older, vulnerable cryptographic methods on that account.
This mechanism directly addresses “harvest now, decrypt later” (HNDL) attacks, where adversaries record encrypted blockchain data today with the intention of decrypting it once quantum computing matures. By forcing a one-way transition, Naoris eliminates the window where old signatures could be exploited.
Testnet results and early traction
Before the mainnet went live, Naoris completed testnet operations in November 2025. The results were substantial: 106 million post-quantum transactions processed, 603 million security threats detected and blocked, 3.35 million wallets created, and over 1 million security nodes activated globally.
The mainnet launched in an invite-only genesis validator phase restricted to strategic partners. Broader public access is planned in subsequent phases, though Naoris has not published a specific timeline for open enrollment.
Draper Associates, the venture firm led by Tim Draper, is a backer. The advisory board includes former Norwegian cyber defense officials and national security experts. In January 2026, Mova Chain made a strategic investment to integrate Naoris’ security layer into card payment infrastructure.
Regulatory signals
In October 2025, Naoris Protocol was cited in a 63-page research document submitted to the U.S. Securities and Exchange Commission as part of the Post-Quantum Financial Infrastructure Framework (PQFIF). The document designated Naoris as a reference model for how financial institutions could approach quantum-resistant migration.
That SEC mention matters because it signals regulatory awareness that quantum threats to financial infrastructure are real enough to warrant formal study. For institutional players evaluating blockchain security solutions, an SEC-cited framework carries weight.
The protocol also won “Best DePIN Project” at the Crypto Impact Awards 2025, recognizing its approach to decentralized physical infrastructure security.
What comes next
Naoris aims to extend its quantum-resistant security layer to L1 and L2 blockchains, centralized exchanges, DeFi protocols, custodian systems, tokenized real-world assets, CBDCs, and cross-chain bridges. Each of those integrations will need to be validated independently, and adoption will depend on whether existing protocols see the quantum threat as urgent enough to invest in migration now.
With Google targeting 2029 for quantum readiness, that urgency is growing. The question for the broader crypto industry is no longer whether post-quantum cryptography is necessary, but whether projects will migrate fast enough before Q-Day arrives.
FAQ
What is post-quantum cryptography and why does blockchain need it?
Post-quantum cryptography uses mathematical algorithms that quantum computers cannot efficiently solve. Current blockchains rely on elliptic curve cryptography, which a sufficiently powerful quantum computer could break using Shor’s algorithm, exposing private keys and enabling theft of funds.
When could quantum computers actually threaten Bitcoin and Ethereum?
Google revised its post-quantum migration target to 2029, and researchers recently reduced the quantum resources needed to break RSA-2048 encryption by a factor of 20. While exact timelines are uncertain, the threat has shifted from theoretical to a near-term planning concern for the industry.
How does Naoris Protocol differ from other quantum-resistant blockchain projects?
Naoris is built natively with NIST Security Level 5 cryptography (CRYSTALS-Dilithium ML-DSA-87) rather than retrofitting existing chains. It also enforces an irreversible transition: once a user adopts post-quantum keys, the network permanently blocks older cryptographic methods on that account.
