Notes

• Hash-based signature schemes depend on hash function assumptions, compatible with Bitcoin's existing design, making them a potential post-quantum alternative
• By optimizing parameters and limiting the number of signatures per public key, significantly reducing signature size and improving efficiency
• Applied SPHINCS+C, TL-WOTS-TW, PORS+FP, etc., outperforming standardized SPHINCS+ (SLH-DSA)
• Discussed limitations in practical applications such as key derivation, multi-signature, and threshold signature
• Provided public scripts to ensure the reproducibility and transparency of the research
• Focused on Bitcoin, providing practical guidance for post-quantum cryptography deployment in blockchain

• 基于哈希的签名方案依赖哈希函数假设，与比特币现有设计兼容，是潜在的后量子替代方案
• 通过参数优化和限制每公钥签名数量，显著减小了签名大小，提升了效率
• 应用了SPHINCS+C、TL-WOTS-TW、PORS+FP等最新优化技术，优于标准化的SPHINCS+（SLH-DSA）
• 讨论了密钥派生、多重签名和阈值签名等应用的局限性
• 提供了公开脚本以确保研究的可复现性和透明度
• 专注于比特币特定需求，为后量子密码学在区块链中的部署提供实用指导
