Frequently asked quantum questions (FAQQ) is a wikimedia website towards answering, in a well-referenced fashion, common statements, assertions, and misconceptions about how quantum computing will effect Bitcoin along with the rest of the blockchain space.
It's put together by contributing members from the Quantum Resistant Ledger.
- Bitcoin's developers have already planned for this.
- Bitcoin will just hard/softfork
- If they can break SHA_256, we’ll upgrade to SHA_384
- But if you don’t reuse addresses, you’re safe because BTC only exposes the hash of your public key if you have never transferred BTC from that address
- Quantum computing is a long ways away, there's no need to bother
- If ECDSA will be broken, banks and the whole internet is broken. Blockchain is the least we’ll need to worry about then.
