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.

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.

通过这一发展，BOB 将成为第一个既继承比特币安全性又开发基于 BitVM 的原型桥的第 2 层解决方案。 BitVM 是一个革命性的系统，它使程序能够在比特币上乐观地执行，而不需要任何分叉或协议更改，从而为 BTC 解锁新的实用性和可扩展性水平。

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.

这一成就是追求去中心化和安全的比特币桥接的一个重要里程碑。现有的桥梁通常依赖于中心化实体（例如 Wrapped Bitcoin (wBTC) 和 Coinbase Wrapped Bitcoin (cbBTC)）或半信任网络（例如 tBTC），其中 BTC 存款和取款的安全性取决于大多数参与者的诚实性。相比之下，BitVM 桥引入了一种卓越的安全模型：只要至少一方诚实行事，BTC 存款和取款就保持安全。任何人都可以提出挑战以确保资金安全。

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.

至关重要的是，BOB 的联合创始人 Alexei Zamyatin 是 BitVM2 技术论文的核心研究贡献者和合著者，为 BOB 团队提供了对这种方法潜力的无与伦比的洞察力。

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

BOB 联合创始人兼 BitVM 核心研究贡献者 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.”

“比特币安全性和信任最小化的 BTC 桥接是比特币 L2 与所有其他链的区别所在。来自最强大和去中心化网络的安全性，以及无需信任任何第三方即可存入和提取 BTC 的方式。到目前为止，这是不可能的，几乎所有 BTC 桥都是可信的多重签名。直到现在，我们才终于拥有了在 BitVM2 实践中实现这一目标的蓝图和原型，这在比特币历史上还是第一次。”

“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.”

“比特币安全性和信任最小化的 BTC 桥接是比特币 L2 的两个最重要的支柱。以前被视为遥不可及的圣杯，现在可以通过比特币质押和 BitVM2 来实现。”

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.

为了加速 BitVM2 的实施，BOB 与 Fiamma 合作，Fiamma 是第一批利用 BitVM2 的产品的先驱，包括第一个 BitVM 桥和第一个基于 BitVM 的比特币验证层。他们共同部署了关键的桥接基础设施，并试用了证明者软件的早期版本，以验证 BOB 的共识。在此原型公开交付后，下一步将是于 2025 年初在 BOB 测试网上推出 BitVM 桥，然后在成功审核和合作伙伴集成后进行主网部署。

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

Fiamma 联合创始人兼 BitVM 核心贡献者 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.”

“我们很高兴宣布与 BOB 团队建立合作伙伴关系！我们非常感谢 Alexei 和他的团队在我们的讨论中提出的宝贵见解。我们期待将 BitVM Bridge 集成到 BOB 中，使其成为第一个具有信任最小化桥的比特币第 2 层。我们希望 BOB 的 BitVM 桥原型是我们战略合作伙伴关系带来的众多令人印象深刻的公告中的第一个。”

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.

公开发布后，该桥将允许 BOB 用户在不依赖第三方的情况下存入和提取 BTC。他们将能够将 BTC 锁定在比特币上，并在 BOB 上铸造完全可替代的 ERC20 桥接 BTC，然后随时将 BTC 赎回为比特币。在理想情况下，桥接过程单程时间不到一小时，这比现有的以太坊 L1 或 L2 桥接比特币要快得多。

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.

本周早些时候，BOB 还宣布计划与领先的 BTC 质押协议 Babylon 整合，这将把 BOB 打造成一个比特币安全网络，并为其区块链提供比特币最终确定性。信任最小化桥接和比特币最终确定性是 BOB 混合设计的重要组成部分，旨在将比特币的安全性和流动性与以太坊的 DeFi 创新和多功能性结合起来，将 BOB 打造成 BTC DeFi 的家园。

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.

成功的桥原型测试开始了 BOB 路线图第二阶段的推出，因为它成为具有比特币最终确定性的以太坊 L2，利用增强的安全性、信任最小化的 BitVM BTC 桥以及在本机 ETH 桥上更快的提款。

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 支持一个蓬勃发展的生态系统，其 DeFi 总价值锁定 (TVL) 超过 2 亿美元，其中包括 Lombard、Solv、Bedrock 和 PumpBTC 的 BTC LST。此外，BOB的一键质押产品BOB Stake将通过与Stake Rewards、Pell、Xverse Earn和埃弗斯塔克。
