Naoris Protocol launches a quantum-resistant blockchain amid concerns about Q-Day

Naoris Protocol launched a quantum-resistant blockchain on Thursday, claiming that the system is designed to remain secure even against the extremely powerful quantum computers of the future that could break modern cryptography.

“Mainnet represents the shift from proof of concept to production infrastructure. The network has verified more than 100 million transactions with post-quantum cryptography. This is not a roadmap promise; it’s measured operational capability,” Nathaniel Szerezla, Head of Growth at Naoris Protocol, said.

The launch comes amid heightened concerns for legacy chains like Bitcoin and Ethereum, which face the threat of a “quantum catastrophe.” Called Q-Day, it’s the moment when future quantum computers could crack the encryption layer protecting most blockchains.

Concerns have surged this week after Google said a quantum computer strong enough could break the Bitcoin blockchain with fewer than 500,000 qubits—far less than earlier estimates. At the same time, another report warned that potential vulnerabilities on Ethereum could put $100 billion on the blockchain at risk.

Because blockchain transactions like those on Bitcoin and Ethereum are permanent, any weaknesses today could be exploited by future quantum computers once they reach sufficient power.

How Naoris is different

This is what sets Naoris apart. According to a press release shared with CoinDesk, the project is built from the ground up with post-quantum cryptography and algorithms approved by the U.S. National Institute of Standards and Technology to protect accounts, transactions, and digital assets.

The system integrates an “irreversible security migration process.” This means that once users have adopted post-quantum keys, they must use quantum-resistant signatures for transactions. The protocol will automatically block transaction attempts that use traditional cryptographic methods—which are more vulnerable to attacks—thereby helping protect assets even if classical cryptography is disabled.

More importantly, even though the quantum-resistant security layer is currently available only on its own dedicated mainnet, the system is built with a broader scope to support wallets, exchanges, Layer 2 networks, and DeFi platforms in the future.

The mainnet was rolled out alongside a group of strategic partners, who run the first validating nodes and form the network’s initial trust layer—laying a solid foundation before wider expansion. The protocol was tested at scale during a long-running testnet phase, in which the system detected and mitigated more than 603 million threats, handled more than 106 million post-quantum transactions, created more than 3.3 million wallets, and activated more than one million security nodes worldwide.

The native token NAORIS is the operating fuel of the network, helping secure transactions, enforce rules, and build trust among users. At the time of writing, the token’s market capitalization is $36 million.
