Quantum‑Ready Blockchains: New Network Claims Safety from Future Computers

Naoris Protocol has just gone live on its main network, announcing it is the first blockchain built from the start with post‑quantum cryptography approved by U. S. standards. The move follows growing worries that powerful quantum machines could crack the math behind today’s most common signatures, such as ECDSA used by Bitcoin and Ethereum. A quantum computer running Shor’s algorithm could pull private keys from public ones, letting bad actors hijack wallets. Naoris says it chose the finalized NIST standard, ML‑DSA (the published form of CRYSTALS‑Dilithium), instead of early experimental versions. The team argues that treating Dilithium and ML‑DSA as the same is a mistake; in reality, ML‑DSA is just the official name of the approved algorithm. By sticking to this single standard, Naoris hopes to avoid confusion and make security easier to audit. Other major chains are also planning changes. Ethereum co‑founder Vitalik Buterin has outlined a roadmap to swap out vulnerable signatures for quantum‑resistant ones. Bitcoin developers are pushing BIP 360, which would limit the exposure of public keys in transactions and lay groundwork for future quantum‑safe signatures.Because every transaction on a blockchain is permanently recorded, the public keys and signatures that protect them stay visible forever. If quantum computers become powerful enough, attackers could scan old blocks to recover private keys from exposed signatures. Naoris addresses this by forcing a hard switch: once an account adopts a post‑quantum key, the network rejects any transaction that uses only classical signatures. The system checks each incoming transaction against a registry of post‑quantum accounts and demands a valid ML‑DSA signature if the account is bound. Before launching its main network, Naoris ran a testnet that handled over 106 million post‑quantum transactions and flagged more than 603 million potential security issues. The project currently has a limited number of validators but plans to grow. Because it cannot retroactively protect assets already on other chains, Naoris encourages users to move funds onto its network. Moving early reduces the window of vulnerability for those who stay on classical blockchains.
