比特币开发者与 StarkWare、Blockstream 合作声称在契约方面取得突破

享有盛誉的开发团队表示，新方法虽然仍需要完善，但可以为比特币区块链带来更大的可编程性

A group of top Bitcoin developers say they have found a way to add a type of programming known as "covenants" to the Bitcoin blockchain without needing to pass a soft fork.

一群顶级比特币开发商表示，他们已经找到了一种方法，可以在比特币区块链中添加一种称为“契约”的编程类型，而无需通过软分叉。

The technique, which is still under development, could unlock crucial functionality such as new wallet and vault features and more efficient layer-2 protocols.

该技术仍在开发中，可以解锁关键功能，例如新的钱包和保险库功能以及更高效的第 2 层协议。

Importantly, the method does not require changing Bitcoin's main underlying code, a notoriously difficult process where consensus is typically seen as the threshold needed to greenlight major upgrades known as a "soft fork."

重要的是，该方法不需要更改比特币的主要底层代码，这是一个众所周知的困难过程，共识通常被视为批准称为“软分叉”的重大升级所需的门槛。

The announcement was made on Thursday in a research paper titled, "ColliderScript: Covenants in Bitcoin via 160-bit hash collisions."

这一消息是周四在一篇题为“ColliderScript：通过 160 位哈希冲突实现比特币契约”的研究论文中宣布的。

The publication comes as Bitcoin, the oldest and largest blockchain, has attracted hordes of developers trying to add programmability and additional network layers that could lead to not only more applications being built atop the peer-to-peer network but also faster and cheaper venues for transaction execution. The goal is to catch up to what Ethereum, the second-largest blockchain, has achieved — but with Bitcoin's famously robust security.

该出版物发布之际，最古老、最大的区块链比特币吸引了大批开发人员，试图增加可编程性和额外的网络层，这不仅可以在点对点网络上构建更多的应用程序，而且可以为开发者提供更快、更便宜的场所。交易执行。我们的目标是赶上第二大区块链以太坊所取得的成就，但同时又具有比特币众所周知的强大安全性。

'Pretty awesome idea'

“非常棒的主意”

The team was led by Ethan Heilman, who separately is one of the authors of a proposed technique known as OP_CAT that could increase Bitcoin's programmability. However, that effort would require changes to the Bitcoin software, as would a separate proposal for covenants known as OP_CTV, proposed by the developer Jeremy Rubin.

该团队由 Ethan Heilman 领导，他是一项名为 OP_CAT 的拟议技术的作者之一，该技术可以提高比特币的可编程性。然而，这一努力需要对比特币软件进行更改，开发人员杰里米·鲁宾 (Jeremy Rubin) 提出了一项名为 OP_CTV 的单独提案。

Other authors of the new research paper include Victor Kobolov and Avihu Levy of the StarkWare project and Andrew Poelstra, a longtime Bitcoin developer who currently serves as head of research at Blockstream.

这篇新研究论文的其他作者包括 StarkWare 项目的 Victor Kobolov 和 Avihu Levy，以及长期比特币开发人员、目前担任 Blockstream 研究主管的 Andrew Poelstra。

StarkWare's official account on X posted a link to the paper on Thursday, adding only a rocket emoji.

StarkWare 在 X 上的官方账户周四发布了该论文的链接，仅添加了一个火箭表情符号。

Robin Linus, a Bitcoin developer who has made waves for a project known as BitVM and more recently BitVM2 that could unlock greater programmability, told CoinDesk in a Telegram message that the research paper was "not really practical" in its current form but represented a "pretty awesome idea."

Robin Linus 是一名比特币开发者，他为 BitVM 和最近的 BitVM2 项目掀起了波澜，该项目可以解锁更大的可编程性，他在 Telegram 消息中告诉 CoinDesk，该研究论文目前的形式“并不真正实用”，但代表了“非常棒的主意。”

"It would cost like north of $10m to execute such a covenant, but the idea behind it is ingenious," Linus said. "I hope people will try to come up with optimizations to make it practical."

“执行这样的契约需要花费 1000 万美元以上，但其背后的想法很巧妙，”Linus 说。 “我希望人们能够尝试提出优化以使其实用。”
