宣布达里亚斯！ 🎉完整交叉输入签名聚合的第一个加密协议，该协议允许重复使用比特币曲线SECP256K1。

2025年4月17日，研究人员NCKLR宣布了Dahlias的推出（“基于离散对数的交互式汇总签名”），这是一种新的加密协议，旨在启用完整的交叉输入签名聚合，同时与比特币现有的SECP256K1 Elliptic elliptic elliptic eLliptic eLliptic eLliptic curve保持兼容。

Researchers have developed a new cryptographic protocol called Discrete Logarithm-Based Interactive Aggregate Signatures (DahLIAS), which aims to enable full cross-input signature aggregation while remaining compatible with Bitcoin's secp256k1 elliptic curve.

DahLIAS introduces a 64-byte aggregate signature structure, achieving roughly double the verification speed compared to half-aggregated Schnorr signatures. Notably, DahLIAS requires only a two-round signing process among participants. This design offers potential improvements in both transaction efficiency and scalability for Bitcoin and related protocols.

Dahlias引入了64个字节的骨料签名结构，与半聚集的schnorr签名相比，验证速度的两倍。值得注意的是，大丽花只需要参与者的两轮签名过程。该设计为比特币和相关协议的交易效率和可扩展性提供了潜在的提高。

The full academic paper detailing DahLIAS is available on the International Association for Cryptologic Research (IACR) ePrint archive, providing an in-depth explanation of the scheme's technical underpinnings and security assumptions.

全部学术论文详细介绍了达利亚斯（Dahlias），可在国际加密研究协会（IACR）EPRINT档案中获得，可深入解释该计划的技术基础和安全假设。

DahLIAS builds on broader research efforts into Cross-Input Signature Aggregation (CISA) for Bitcoin, an area of active development aimed at reducing transaction sizes, lowering fees, and improving privacy. A 2024 research paper sponsored by the Human Rights Foundation (HRF) outlined the significance of CISA for Bitcoin's future.

Dahlias以更广泛的研究工作为基础，用于比特币的交叉输入签名聚合（CISA），该领域旨在减少交易规模，降低费用和改善隐私。由人权基金会（HRF）赞助的2024年研究论文概述了CISA对比特币未来的重要性。

"Aggregating multiple signatures across transaction inputs could lower transaction costs, encourage privacy-enhancing tools like CoinJoin, and reduce network congestion, ultimately paving the way for a more efficient and scalable Bitcoin network," the HRF paper stated.

HRF论文说：“跨交易输入的多个签名可以降低交易成本，鼓励增强隐私的工具，例如CoinJoin，并减少网络拥塞，最终为更有效，更可扩展的比特币网络铺平了道路。”

Bitcoin's Taproot upgrade in 2021 introduced Schnorr signatures, enabling limited forms of aggregation within single multi-signature transactions. However, cross-input aggregation—combining signatures across multiple inputs with different ownership—remained a complex challenge due to technical risks such as rogue key attacks and interactivity requirements.

比特币在2021年的Taproot升级引入了Schnorr签名，从而在单个多签名交易中实现了有限的聚合形式。但是，由于技术风险（例如Rogue键攻击和互动性要求），跨输入汇总（将多个输入跨多个输入之间的签名都重新确定。

DahLIAS addresses some of these challenges by leveraging interactive aggregation while maintaining compatibility with Bitcoin's established cryptographic standards. Although its adoption would require further development and potentially consensus changes, DahLIAS represents a notable advancement in ongoing efforts to make Bitcoin transactions more efficient and private.

Dahlias通过利用交互式聚合来解决其中一些挑战，同时保持与比特币已建立的加密标准的兼容性。尽管它的采用将需要进一步发展并有可能发生共识的变化，但Dahlias代表了正在进行的努力使比特币交易更加高效和私密的努力的显着进步。

The DahLIAS project was developed by a team including cryptographers Yannick Seurin and Tim Ruffing, with contributions from Ncklr, highlighting the collaboration between academic research and Bitcoin development communities.

Dahlias项目是由一个由密码学家Yannick Seurin和Tim Ruffing在内的团队开发的，并由NCKLR贡献了，强调了学术研究与比特币发展社区之间的合作。

Further research and real-world testing will determine whether DahLIAS or similar protocols will be proposed for integration into Bitcoin's protocol roadmap.

进一步的研究和现实世界测试将决定是否将提出Dahlias或类似协议，以集成到比特币的协议路线图中。
