BOB 成功測試了其首個由 BitVM 驅動、信任最小化的比特幣橋原型

BOB（「基於比特幣建構」）是由比特幣和以太坊支援的混合第2 層(L2)，與領先的BitVM 開發人員Fiamma 合作，成功測試了其第一個由BitVM 驅動、信任最小化的比特幣橋的原型。

BOB (“Build on Bitcoin”), a hybrid layer 2 (L2) powered by Bitcoin and Ethereum, has successfully tested a prototype for its first BitVM-powered, trust-minimized Bitcoin bridge, in partnership with Fiamma, a leading BitVM developer and zero-knowledge infrastructure company.

BOB（「基於比特幣建構」）是由比特幣和以太坊支援的混合第2 層(L2)，與領先的BitVM 開發人員Fiamma 合作，成功測試了其第一個由BitVM 驅動、信任最小化的比特幣橋的原型。

With this development, BOB will become the first Layer 2 solution to both inherit Bitcoin’s security and develop a prototype BitVM-based bridge. BitVM is a revolutionary system that enables programs to be executed on Bitcoin optimistically, without requiring any forks or protocol changes, unlocking new levels of utility and scalability for BTC.

透過這項發展，BOB 將成為第一個既繼承比特幣安全性又開發基於 BitVM 的原型橋的第 2 層解決方案。 BitVM 是一個革命性的系統，它使程式能夠樂觀地在比特幣上執行，而不需要任何分叉或協議更改，從而為 BTC 解鎖新的實用性和可擴展性水平。

This achievement is a significant milestone in the quest for decentralized and secure Bitcoin bridging. Existing bridges typically rely on either centralized entities—such as Wrapped Bitcoin (wBTC) and Coinbase Wrapped Bitcoin (cbBTC)—or semi-trusted networks like tBTC, where the security of BTC deposits and withdrawals depends on the honesty of the majority of participants. In contrast, BitVM bridges introduce a superior security model: BTC deposits and withdrawals remain secure as long as at least one party acts honestly. Anyone can raise a challenge to ensure funds remain safe.

這項成就是追求去中心化和安全的比特幣橋接的一個重要里程碑。現有的橋樑通常依賴中心化實體（例如Wrapped Bitcoin (wBTC) 和Coinbase Wrapped Bitcoin (cbBTC)）或半信任網路（例如tBTC），其中BTC 存款和提款的安全性取決於大多數參與者的誠實性。相較之下，BitVM 橋引入了卓越的安全模型：只要至少一方誠實行事，BTC 存款和提款就保持安全。任何人都可以提出挑戰以確保資金安全。

Crucially, BOB’s co-founder Alexei Zamyatin is a core research contributor and co-author of the BitVM2 technical paper, providing the BOB team with unparalleled insight into the potential of this approach.

至關重要的是，BOB 的聯合創始人 Alexei Zamyatin 是 BitVM2 技術論文的核心研究貢獻者和合著者，為 BOB 團隊提供了對這種方法潛力的無與倫比的洞察力。

Alexei Zamyatin, BOB Co-Founder and core BitVM research contributor said:

BOB 聯合創辦人兼 BitVM 核心研究貢獻者 Alexei Zamyatin 表示：

“Bitcoin security and trust-minimized BTC bridging is what sets Bitcoin L2s apart from all other chains. Security from the most robust and decentralised network, paired with a way to deposit and withdraw BTC without trusting any third party. So far, this has not been possible, almost all BTC bridges are trusted multisigs. Only now, for the first time in Bitcoin’s history, do we finally have a blueprint and a prototype for achieving this in practice with BitVM2.”

「比特幣安全性和信任最小化的 BTC 橋接是比特幣 L2 與所有其他鏈的區別所在。來自最強大和去中心化網路的安全性，以及無需信任任何第三方即可存入和提取 BTC 的方式。到目前為止，這是不可能的，幾乎所有 BTC 橋都是可信的多重簽名。直到現在，我們終於擁有了在 BitVM2 實踐中實現這一目標的藍圖和原型，這在比特幣歷史上還是第一次。

“Bitcoin security and trust-minimized BTC bridging are the two most important pillars of Bitcoin L2s. Previously treated as the unreachable holy grail, this can now be achieved via Bitcoin staking and BitVM2.”

「比特幣安全性和信任最小化的 BTC 橋接是比特幣 L2 的兩個最重要的支柱。以前被視為遙不可及的聖杯，現在可以透過比特幣質押和 BitVM2 來實現。

To accelerate its implementation of BitVM2, BOB has teamed up with Fiamma, the pioneer behind the first products utilizing BitVM2, including the first BitVM bridge and the first BitVM-powered verification layer on Bitcoin. Together they have deployed key bridge infrastructure and trialed an early version of the prover software to verify BOB’s consensus. Following this prototype’s public delivery, the next steps will be the rollout of the BitVM bridge on the BOB testnet in early 2025, and then the mainnet deployment after successful audit and partner integration.

為了加速 BitVM2 的實施，BOB 與 Fiamma 合作，Fiamma 是第一批利用 BitVM2 的產品的先驅，包括第一個 BitVM 橋接器和第一個基於 BitVM 的比特幣驗證層。他們共同部署了關鍵的橋接基礎設施，並試用了證明者軟體的早期版本，以驗證 BOB 的共識。在此原型公開交付後，下一步將是於 2025 年初在 BOB 測試網上推出 BitVM 橋，然後在成功審核和合作夥伴整合後進行主網部署。

Cyimon Chen, Fiamma Co-founder and core BitVM contributor said:

Fiamma 聯合創辦人兼 BitVM 核心貢獻者 Cyimon Chen 表示：

“We’re excited to announce our partnership with the BOB team! We deeply appreciate Alexei and his team’s valuable insights during our discussions. We look forward to integrating the BitVM Bridge into BOB, making it the first Bitcoin Layer 2 with a trust-minimized bridge. We hope BOB’s BitVM bridge prototype is the first of many impressive announcements that result from our strategic partnership.”

「我們很高興宣布與 BOB 團隊建立合作夥伴關係！我們非常感謝 Alexei 和他的團隊在我們的討論中提出的寶貴見解。我們期待將 BitVM Bridge 整合到 BOB 中，使其成為第一個具有信任最小化橋的比特幣第 2 層。我們希望 BOB 的 BitVM 橋接原型是我們戰略合作夥伴關係帶來的眾多令人印象深刻的公告中的第一個。

Upon public release, the bridge will allow BOB users to deposit and withdraw BTC without relying on a third party. They will be able to lock BTC on Bitcoin and mint a fully fungible ERC20 bridged BTC on BOB, and then redeem BTC back to Bitcoin at any time. In the ideal case, the bridging process will take less than one hour each way, which is much faster than existing Ethereum L1 or L2 bridges to Bitcoin.

公開發布後，該橋將允許 BOB 用戶在不依賴第三方的情況下存入和提取 BTC。他們將能夠將 BTC 鎖定在比特幣上，並在 BOB 上鑄造完全可替代的 ERC20 橋接 BTC，然後隨時將 BTC 贖回為比特幣。在理想情況下，橋接過程單程時間不到一小時，這比現有的以太坊 L1 或 L2 橋接比特幣要快得多。

Earlier this week, BOB also announced its planned integration with Babylon, the leading BTC staking protocol, which will establish BOB as a Bitcoin-secured network and provide Bitcoin finality to its blockchain. Trust-minimized bridging and Bitcoin finality are essential components of BOB’s hybrid design, which aims to combine Bitcoin’s security and liquidity with Ethereum’s DeFi innovation and versatility, establishing BOB as the home for BTC DeFi.

本週早些時候，BOB 還宣布計劃與領先的 BTC 質押協議 Babylon 整合，這將把 BOB 打造成一個比特幣安全網絡，並為其區塊鏈提供比特幣最終確定性。信任最小化橋接和比特幣最終確定性是BOB 混合設計的重要組成部分，旨在將比特幣的安全性和流動性與以太坊的DeFi 創新和多功能性結合起來，將BOB 打造成BTC DeFi 的家園。

The successful bridge prototype test starts the rollout of phase 2 of BOB’s roadmap, as it becomes an Ethereum L2 with Bitcoin finality, leveraging enhanced security, a trust-minimized BitVM BTC bridge, and faster withdrawals on the native ETH bridge.

成功的橋原型測試開始了BOB 路線圖第二階段的推出，因為它成為具有比特幣最終確定性的以太坊L2，利用增強的安全性、信任最小化的BitVM BTC 橋以及在本機ETH 橋上更快的提款。

Currently, BOB supports a thriving ecosystem with $200+ million in DeFi Total Value Locked (TVL), featuring BTC LSTs by Lombard, Solv, Bedrock, and PumpBTC. In addition, BOB’s 1-click staking product, BOB Stake, will make it easy for millions of users to stake BTC in DeFi with just a single Bitcoin transaction, through integrations with third-party staking services like Staking Rewards, Pell, Xverse Earn and Everstake.

目前，BOB 支援一個蓬勃發展的生態系統，其 DeFi 總價值鎖定 (TVL) 超過 2 億美元，其中包括 Lombard、Solv、Bedrock 和 PumpBTC 的 BTC LST。此外，BOB的一鍵質押產品BOB Stake將通過與Stake Rewards、Pell、Xverse Earn和埃弗斯塔克。
