The discussion around Bitcoin and quantum computing often swings between two extremes:
- It is dismissed as pure FUD (as some have argued).
- It is treated as an inevitable cryptographic apocalypse.
I’m not interested in either framing, i’m just looking for a technical answer.
My question: Is it accurate to call the quantum threat a “myth”?: If sufficiently advanced quantum systems are developed in the future, could exposed public keys
practically theoritically become vulnerable?
We know Bitcoin is not static (it’s still labeled beta, after all). So, signature schemes can be upgraded.
Now a
second question follows:
If a large-scale quantum computer capable of breaking secp256k1 were eventually built, is migration to quantum-resistant cryptography technically feasible within Bitcoin’s consensus model?
In other words, my real concern is’nt whether quantum computers exist today. It is rather; if Bitcoin can adapt before such machines become practically usable.
Bitcoin’s history shows strong adaptability, but cryptographic transitions are not trivial. i would be interested in hearing technical perspectives on how realistic such a migration would be.
