Will Quantum Break Crypto? The Truth
summary
Claim: widely used elliptic curve wallets with an outgoing transaction break once a sufficiently powerful quantum (IBM Condor class ~1,000+ qubits) is available, and account‑based chains like Ethereum fail en masse because signatures can be forged. Recent algorithmic improvements lower qubit counts needed versus classic Shor estimates. Migration forces hard forks required for migration and still leaves funds in abandoned wallets vulnerable to theft because legitimate migrations are indistinguishable from attackers. QANPlatform offers a ground‑up quantum‑resistant chain using cross‑signatures (EC + post‑quantum) and normal programming languages for developer migration.
