长期以来，比特币限于其作为价值存储的角色，在defi中取得了决定性的突破

随着SUI网络上PEG-BTC（YBTC）令牌的启动，Bitlayer引入了“无信任的” BITVM桥，消除了集中式中介机构。

Long confined to its role as a store of value, Bitcoin is making a decisive breakthrough in DeFi.

长期以来，比特币局限于其作为价值存储的角色，在Defi中取得了决定性的突破。

This initiative marks a significant evolution. BTC becomes a fully usable asset within decentralized protocols, previously dominated by native tokens. A new chapter opens, that of an interoperable, mobile Bitcoin now active in programmable finance.

该计划标志着一个重大的演变。 BTC成为分散协议中的完全可用资产，以前由天然令牌主导。一个新的章节打开了，即可互操作的移动比特币现在活跃于可编程融资中。

YBTC: a bridge between Bitcoin and DeFi on Sui

YBTC：SUI上的比特币与Defi之间的桥梁

Bitlayer officially launched Peg-BTC (YBTC) on the Sui network on May 15, via the integration of a “trustless” BitVM Bridge.

Bitlayer于5月15日通过集成“无信任的” BITVM桥在SUI网络上正式启动PEG-BTC（YBTC）。

Such an initiative was announced by Bitlayer on its X account.

Bitlayer在其X帐户上宣布了这样的计划。

Pour le premier jeton BTC encodé sur un réseau DeFi, Bitlayer choisit Sui. L'intégration du BitVM Bridge permet de rendre BTC productif sur Sui grâce à YBTC.

对于在Defi网络上编码的第一个BTC令牌，BitLayer选择SU。 BITVM桥的整合使您有可能通过YBTC使BTC生产性SU SU。

Pour rappel, this synthetic token allows investors to deposit their BTC on Bitlayer to convert it into YBTC on Sui, thus opening access to various DeFi applications on the network.

倒数拼图，这个合成令牌允许投资者将其BTC存放在Bitlayer上，以将其转换为SUI上的YBTC，从而打开网络上各种DEFI应用程序的访问。

This launch enables the following features:

此启动可实现以下功能：

Since February 2025, shared data indicates that over 587 BTC have been integrated into Sui’s DeFi ecosystem, representing more than 10% of its TVL. The launch of YBTC aims to accelerate this momentum by broadening the base of active Bitcoin investors in DeFi.

自2025年2月以来，共享数据表明，超过587 BTC已集成到SUI的Defi生态系统中，占其TVL的10％以上。 YBTC的推出旨在通过扩大DEFI的活跃比特币投资者的基础来加速这一势头。

BitVM Bridge Technology: Security, Interoperability, and Multi-Chain Ambitions

BITVM桥技术：安全性，互操作性和多链野心

The project’s technological specificity lies in using the BitVM Bridge, a trustless bridge solution. This mechanism, still rare in the BTC ecosystem, enables native locking of BTC on the Bitlayer layer before converting it into YBTC on Sui, without centralized intermediaries responsible for custodianship.

该项目的技术特异性在于使用BITVM Bridge，这是一种无信任的桥解决方案。这种机制在BTC生态系统中仍然很少见，可以使BTC在比特层层上的天然锁定，然后将其转换为SUI上的YBTC，而无需负责监护人的集中式中介机构。

“The BitVM Bridge is designed to eliminate risks associated with intermediaries while ensuring transaction verifiability through a proof architecture,” explains Bitlayer in its technical documentation.

Bitlayer在其技术文档中解释说：“ BITVM桥梁旨在消除与中间人相关的风险，同时通过证明架构确保交易验证性。”

However, the ambition of the BitVM Bridge goes far beyond just the use case on Sui. Bitlayer already announces a roadmap expanding to other major ecosystems such as Base, Starknet, Arbitrum, Sonic, Cardano, and Plume Network.

但是，BITVM桥的野心远远超出了SUI上的用例。 Bitlayer已经宣布了一个路线图扩展到其他主要生态系统，例如基本，Starknet，inotum，sonic，cardano和羽状网络。

This multi-chain strategy could allow Peg-BTC to become an interoperable standard for BTC tokenization across different DeFi networks. Audits and bridge testing are ongoing, aiming for broader deployment in the coming weeks.

这种多链策略可以使PEG-BTC成为跨不同DEFI网络的BTC令牌化的可互操作标准。审计和桥梁测试正在进行中，旨在在接下来的几周内进行更广泛的部署。

While securing BTC flows is a technological priority, this advancement raises questions about the future of DeFi. By providing an asset historically seen as passive, Bitlayer transforms Bitcoin’s nature in yield and liquidity dynamics. The growing involvement of players like Sui in this dynamic suggests that BTCFi is on its way to structuring itself as an autonomous segment, with its own standards, products, and governance logics. In this context, interoperability could quickly become an essential standard for the multi-chain ecosystem.

尽管确保BTC流是技术的优先事项，但这种进步引发了有关Defi的未来的问题。通过提供历史上被视为被动的资产，Bitlayer在产量和流动性动态方面改变了比特币的性质。像Sui这样的玩家参与这种动态的参与表明，BTCFI正在以自己的标准，产品和治理逻辑为自治部门构建自己。在这种情况下，互操作性可能很快成为多链生态系统的基本标准。
