The emergence of quantum computers poses a significant threat to Bitcoin's security, with approximately 6.5 million tokens worth hundreds of billions of dollars at risk. To mitigate this threat, several initiatives are under consideration, including BIP 360, which removes public keys from the blockchain, and post-quantum signature schemes like SPHINCS+ and SLH-DSA. Other proposals, such as Tadge Dryja's Commit/Reveal scheme and Hourglass V2, aim to protect transactions in the mempool and slow the spending of old coins. While these proposals are still in development, they demonstrate the Bitcoin community's proactive approach to addressing the quantum threat and ensuring the long-term security of the network.
