What is post-quantum cryptography and why does it matter for blockchain?

Post-quantum cryptography refers to encryption algorithms designed to resist attacks from quantum computers. Current blockchains like Bitcoin and Ethereum use ECDSA, which quantum computers could break, potentially giving attackers access to private keys. Post-quantum algorithms like ML-DSA are mathematically resistant to quantum threats.

Will Bitcoin and Ethereum upgrade to post-quantum cryptography?

Both networks are exploring quantum-resistant upgrades. Ethereum has outlined a roadmap, and Bitcoin is advancing through proposals like BIP 360. However, implementation will be slow and complex because it requires coordinated changes across wallets, nodes, and exchanges. There's no guaranteed timeline.

If I move my crypto to Naoris, is it quantum-safe forever?

Moving assets to Naoris protects them from quantum attacks because the network uses post-quantum cryptography from the start. However, assets left on classical blockchains like Bitcoin or Ethereum remain vulnerable. You'd need to actively migrate to be protected.
