Summary:
  • Naoris Protocol launched a Layer 1 blockchain running on NIST-approved post-quantum cryptography (CRYSTALS-Dilithium).
  • The network processed 106 million transactions while blocking 603 million threats during testing.
  • An "irreversible security transition" mechanism permanently blocks legacy cryptographic methods once quantum-resistant keys activate.

Most blockchains were built assuming the math would never break. Naoris Protocol was built assuming it would.

The company just launched its mainnet - a Layer 1 blockchain running on post-quantum cryptography approved by the National Institute of Standards and Technology. The encryption works today and will work after quantum computing changes the math.

The Quantum Threat

Quantum computers don't exist at scale yet. But when they do, they'll shred the encryption protecting every major cryptocurrency.

Bitcoin's addresses become readable. Ethereum's wallets become hackable. Naoris uses CRYSTALS-Dilithium, an algorithm approved by NIST at the highest security tier, instead of waiting for that to happen.

The Permanent Lock-In

Naoris created an "irreversible security transition." Once a user activates quantum-resistant keys, the network automatically blocks anyone using old-style crypto signatures. No backward compatibility.

You can't accidentally use broken security and you can't be tricked into vulnerable transactions - the network simply stops accepting them.

What to Watch

Naoris is in invite-only validator testing with 106 million transactions processed and 603 million threats blocked so far. The real test comes when it opens to retail users. Watch how many existing crypto holders migrate.
