True, but you don't actually print out your private key on a paper wallet -- you print out a seed phrase, from which the key material is derived. So you might even be able to keep using the same seed phrase! (Don't quote me on that, though.)
- 3np 5y agoA 12 words BIP39 phrase is 128 bits of entropy. Is this enough? Depends on the algorithm. In either case, you'd absolutely not want to reuse the phrase. AFAIK BIP-32 does not have security guarantees such that you can't find the seed from a set of private keys.
- Thorrez 5y agoOh, very interesting. I hadn't considered that a quantum-resistant private key might have its security depend on a large amount of input randomness.
