To put it simply: "not much"
To be more specific: "not any more of a threat than a randomly generated 1 address would receive"
If someone were to set out with a goal of finding your seed (ie, not your Private Keys, but your seed, which would give them all your private keys)
They would need to know a large amount of your addresses, and know which type of address it was (Receive or Change) and which order it was. (whether it was the first or second or third etc.)
Then if they had a quantum computer on their side, they could then probably figure it out.
To be honest, if the crypto doesn't level up before quantum computing gets too accessible and programmers get too accustomed to programming for it, then They won't need your seed. They'll just run down the list of highest balance addresses and start hacking away.
Topic: What threat(s) can quantum computing bring to electrum? (Read 521 times)
I hear that cracking ECDSA private key for a known public key is feasible with quantum computing. With non deterministic wallets, the danger can be mitigated by never reusing a bitcoin address, such that the public keys for addresses with balances are not known.
Does the deterministic nature of electrum pose any additional risk in the face of quantum computing?
