Naoris Protocol (@NaorisProtocol): Classical 🆚 Quantum: two machines, two threat models

Classical 🆚 Quantum: two machines, two threat models Classical computers made today’s cryptography feel safe because they work through problems in sequences. Step by step. Attempt by attempt. Key by key. For strong digital signatures, the number of possible keys is so large that even the fastest classical machines hit a wall of time. That is the classical threat model: → Work through possibilities → Search an enormous key space → Run out of time before finding the answer Quantum changes the attack surface. A quantum computer does not just “try faster.” With Shor’s algorithm, it can use the structure of the math itself to attack public-key cryptography in a completely different way. That is the quantum threat model: → Exploit mathematical structure → Break assumptions behind public keys → Turn exposed cryptography into a real risk That matters for blockchains because ECDSA and Ed25519 were built for a classical world. They secure wallets, signatures, transactions, validators, and identities across crypto today. But the assumption was never “hard for every possible machine.” It was “hard for classical machines.” Post-quantum cryptography uses different mathematical foundations, designed for a world where quantum computers exist. That is the shift: not faster computers, but a different class of machine creating a different class of attack. Naoris was built for that standard from day one.
