According to Wu, Blockstream founder Adam Back tweeted that Bitcoin's Taproot leaf nodes reserve support for future post-quantum (PQ) signature mechanisms, which can effectively alleviate fears of quantum computing without the need to currently activate anti-quantum signature opcodes. He believes that the threat of quantum computing is still decades away from becoming a reality, and that anti-quantum signature technology will also introduce more compact and mature solutions in the future. At the same time, he pointed out that through existing Schnorr signatures or future anti-quantum signature schemes, Bitcoin users can safely migrate funds without increasing current transaction costs. He emphasized that this mechanism can help the Bitcoin community prepare in advance while maintaining on-chain efficiency.
