Threshold-Schnorr 集成：比特币和区块链的新时代

互联网计算机协议 (ICP) 宣布门限 Schnorr 签名与链上比特币区块头成功集成

The Internet Computer Protocol (ICP) has successfully integrated threshold-Schnorr signatures with onchain Bitcoin block headers, as part of its ongoing Deuterium milestone, according to an announcement on March 8, 2023. This integration will allow ICP smart contracts to directly interact with Bitcoin, enabling a range of new applications.

根据 2023 年 3 月 8 日的公告，互联网计算机协议 (ICP) 已成功将阈值 Schnorr 签名与链上比特币区块头集成，作为正在进行的 Deuterium 里程碑的一部分。这种集成将允许 ICP 智能合约直接与比特币交互，实现一系列新应用。

The integration of threshold-Schnorr signatures is significant as it will allow ICP smart contracts to perform functions such as signing Taproot transactions and supporting decentralized finance (DeFi) applications. This will boost Bitcoin’s compatibility across platforms and applications, opening up new possibilities for development within the Bitcoin ecosystem.

门限-Schnorr 签名的集成意义重大，因为它将允许 ICP 智能合约执行签署 Taproot 交易和支持去中心化金融（DeFi）应用等功能。这将增强比特币跨平台和应用程序的兼容性，为比特币生态系统内的发展开辟新的可能性。

The milestone will particularly benefit emerging protocols like Ordinal inscriptions and the BRC20 standard, which have already seen substantial success in increasing transaction activity on the Bitcoin network. Developers will now have the tools to create more advanced and trustless applications on Bitcoin, leveraging the capabilities of ICP.

这一里程碑将特别有利于 Ordinal inscriptions 和 BRC20 标准等新兴协议，这些协议在增加比特币网络交易活动方面已经取得了巨大成功。开发人员现在将拥有工具，利用 ICP 的功能，在比特币上创建更先进、更无需信任的应用程序。

“Most Bitcoin meta protocols, like Ordinals and BRC20, utilize Taproot transactions that rely on Schnorr signatures,” said Lomesh Dutta, Vice President of Growth at the Dfinity Foundation. “With threshold-Schnorr, or tSchnorr, ICP smart contracts can now natively sign Bitcoin transactions. This enables developers to explore a wide range of use cases, from creating DeFi lending markets backed by Ordinals to developing infrastructure like decentralized indexers.”

“大多数比特币元协议，如 Ordinals 和 BRC20，都利用依赖 Schnorr 签名的 Taproot 交易，”Dfinity 基金会增长副总裁 Lomesh Dutta 表示。 “通过阈值 Schnorr 或 tSchnorr，ICP 智能合约现在可以本地签署比特币交易。这使开发人员能够探索广泛的用例，从创建由 Ordinals 支持的 DeFi 借贷市场到开发去中心化索引器等基础设施。”

The integration will also expand access to full Bitcoin block headers, up from the previous capability of handling only Bitcoin’s unspent transaction output (UTXO) set. This feature will empower ICP-based projects like Omnity Network and Bioniq to independently verify Bitcoin blocks without relying on external services, enhancing the trustlessness and security of operations across networks.

此次集成还将扩展对完整比特币区块头的访问，而之前只能处理比特币的未花费交易输出（UTXO）集。此功能将使 Omnity Network 和 Bioniq 等基于 ICP 的项目能够独立验证比特币区块，而无需依赖外部服务，从而增强跨网络操作的免信任性和安全性。

This milestone not only advances Bitcoin’s integration into the DeFi sector but also positions ICP as a major player in the broader evolution of Bitcoin's role in the decentralized landscape. The Deuterium milestone is seen as a crucial step towards creating a more interconnected and efficient blockchain environment.

这一里程碑不仅推动了比特币与 DeFi 领域的融合，而且还使 ICP 成为比特币在去中心化领域的角色更广泛演变的主要参与者。 Deuterium 里程碑被视为创建更加互联和高效的区块链环境的关键一步。
