Look not sure how to say this, bit if modern encryption gets broken Bitcoin is the least of everyone's concerns. You are talking about mountains of real economic and infrastructure systems completely fucked.

memes aside, I don't understand what goes on in the mind of smoothbrains. They freak out about crypto whenever quantum computing is mentioned, despite quantum computing being a solved problem in crypto (fork, move to quantum resistant algorithm). And they don't worry about all the companies, hospitals, airports, local power infrastructure, water supply running on legacy systems with no clear upgrade path to anything quantum resistant

>Bitcoin and even other cryptocurrencies and their history are filled with examples of hardware and software changes that had to be made to make the network more secure and performant — and good security practices in the present (avoiding wallet reuse) can help prepare for a more uncertain future.
>So quantum computers being added to the mix won’t suddenly render classical modes of encryption useless or mining trivial — “quantum supremacy” now doesn’t mean that your encryption or the security of bitcoin is at risk right at this moment.
>The real threat is when quantum computers become many scales larger than they currently are — by which point planning for post-quantum encryption, which is already well on the way would come to the fore, and at which point bitcoin and other cryptocurrencies can soft fork — and use both decentralized governance and dynamism when needed in the face of new existential threats to defeat the threat of “quantum supremacy”.

>>29248508
Simply put you only need the private key to control the address. It's just like picking a lock, trying every possible combination.

- The blockchain is entirely public and contains mining and regular transactions with addresses as well as their public keys.
- The code to generate those private and public keys is open source.
- They can extract all addresses and public keys from the blockchain to use in offline brute forcers.

Using the list of known public keys and the code to generate a private & public key pair, they try every combination of recovery phrases since the recovery word list is also public, if any matching public key is found then they have the private key to unlock and transfer.

It would take millions of years for a regular computer but a quantum computer with the right algorithms will reduce that down to a few seconds. Private keys are just a long number.

you can't apply a quantum patch on old addresses. there is no way. and there is no way to move all coins to quantum resistant addresses before quantum supremacy is achieved on the secp256k1.
we can probably move 70% of the coins to addresses that are highly quantum resistant. but say 20% will remain vulnerable. and that is a lot. a lot will remain forever unsalvageable too. the only hope is that even with a q computer it will take a fucking while to "mine" all those vulnerable addresses. and thus it won't cause a panic.

Quantum computing promises exponential speedup (that's super good) for specific problems. Examples are machine learning (HHL algorithm), quantum chemistry (vqe, promising for drug development) and prime factorisation (shors algo, why theyre """dangerous""" for encryption) Of course this is more nuanced in reality and they will probably used in hybrid with classical computers. It is theoretically proven that they provide this speedup, we just have to build better hardware. Some people are sceptical that this is possible, but most are optimistic, especially because of the huge industry interest.

Except quantum computers are a more distant concept than asteroid mining (we've already had a Japanese probe sample and shoot back to earth an asteroid sample).

bitcoin is funny. signature aggregation is coming with taproot. this makes it from hard to impossible to attack with a q computer using new smart types of contracts and the new signature scheme.

also segwit positions bitcoin uniquely it allows for separation of the financial part of the transactions from the signatures (witness) and this makes using way way bigger keys possible without increasing the burden for nodes that only want the ledger synced and accept the transactions in the longest chain valid (like spv nodes) because the nakamoto consensus has a robust and tried incentive structure.

we could double encryption key size way faster than q computers could hope to double qbits for a while.
also post quantum cryptography is coming along the main approach is removing the solution filtering ability thus nulling the advantage of q computers. some traditional cyphers can be trivially adopted in this way practically all symmetric cyphers and hashes.
