The emergence of quantum computers poses a significant threat to Bitcoin's security, with the potential to compromise the cryptocurrency's core cryptography. Developers are actively exploring solutions to mitigate this risk, including proposals such as BIP 360, SPHINCS+, and Tadge Dryja's Commit/reveal scheme.
These initiatives aim to protect Bitcoin against quantum attacks by introducing new output types, hash-based post-quantum signatures, and emergency brakes for the mempool. While these proposals are still in development, they demonstrate the community's proactive approach to addressing the quantum threat and ensuring the long-term security of the Bitcoin network.
