長期以來，比特幣限於其作為價值存儲的角色，在defi中取得了決定性的突破

隨著SUI網絡上PEG-BTC（YBTC）令牌的啟動，Bitlayer引入了“無信任的” BITVM橋，消除了集中式中介機構。

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

長期以來，比特幣局限於其作為價值存儲的角色，在Defi中取得了決定性的突破。

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.

該計劃標誌著一個重大的演變。 BTC成為分散協議中的完全可用資產，以前由天然令牌主導。一個新的章節打開了，即可互操作的移動比特幣現在活躍於可編程融資中。

YBTC: a bridge between Bitcoin and DeFi on Sui

YBTC：SUI上的比特幣與Defi之間的橋樑

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

Bitlayer於5月15日通過集成“無信任的” BITVM橋在SUI網絡上正式啟動PEG-BTC（YBTC）。

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

Bitlayer在其X帳戶上宣布了這樣的計劃。

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.

對於在Defi網絡上編碼的第一個BTC令牌，BitLayer選擇SU。 BITVM橋的整合使您有可能通過YBTC使BTC生產性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.

倒數拼圖，這個合成令牌允許投資者將其BTC存放在Bitlayer上，以將其轉換為SUI上的YBTC，從而打開網絡上各種DEFI應用程序的訪問。

This launch enables the following features:

此啟動可實現以下功能：

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月以來，共享數據表明，超過587 BTC已集成到SUI的Defi生態系統中，佔其TVL的10％以上。 YBTC的推出旨在通過擴大DEFI的活躍比特幣投資者的基礎來加速這一勢頭。

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

BITVM橋技術：安全性，互操作性和多鏈野心

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.

該項目的技術特異性在於使用BITVM Bridge，這是一種無信任的橋解決方案。這種機制在BTC生態系統中仍然很少見，可以使BTC在比特層層上的天然鎖定，然後將其轉換為SUI上的YBTC，而無需負責監護人的集中式中介機構。

“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在其技術文檔中解釋說：“ BITVM橋樑旨在消除與中間人相關的風險，同時通過證明架構確保交易驗證性。”

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橋的野心遠遠超出了SUI上的用例。 Bitlayer已經宣布了一個路線圖擴展到其他主要生態系統，例如基本，Starknet，inotum，sonic，cardano和羽狀網絡。

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.

這種多鏈策略可以使PEG-BTC成為跨不同DEFI網絡的BTC令牌化的可互操作標準。審計和橋樑測試正在進行中，旨在在接下來的幾週內進行更廣泛的部署。

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.

儘管確保BTC流是技術的優先事項，但這種進步引發了有關Defi的未來的問題。通過提供歷史上被視為被動的資產，Bitlayer在產量和流動性動態方面改變了比特幣的性質。像Sui這樣的玩家參與這種動態的參與表明，BTCFI正在以自己的標準，產品和治理邏輯為自治部門構建自己。在這種情況下，互操作性可能很快成為多鏈生態系統的基本標準。
