编者按:

最近 BTCFi 又掀起新浪潮,越来越多的 DeFi 协议盯上了 1.5 万亿美元的肥产,思考如何让 BTC 更具资本效率。

8 月 22 日,Babylon 主网第一阶段正式启动,允许 BTC 持有者将代币锁定在比特币网络上。Babylon 旨在利用比特币的安全性来为其他 PoS 链提供安全保障,同时也能将潜力巨大的流动性引入 DeFi。

Babylon 生态的再质押协议 Lombard 于 21 日推出内测版,并于次日在 Babylon 上线主网后发布。Lombard 的旗舰产品 LBTC 是一种收益型、跨链、流动性强的比特币,以 1:1 的比例由 BTC 支持。7月,Lombard 完成由 Polychain Capital 领投的 1600 万美元种子轮融资。

Lombard 如何利用 LBTC 推动比特币再质押生态系统创新?本文翻译自 Lombard 的官方博客,详细解释了 LBTC 的工作原理。

介绍

Lombard 正致力于通过将比特币的用途从单纯的价值存储转变为一种可生产的金融工具,来推动数字经济的发展。尽管比特币仍是全球最大的加密资产,但这些价值超过万亿美元的比特币往往处于闲置状态,其实际用途相比于其他数字资产是非常有限的。Lombard 认为,将比特币与去中心化金融(DeFi)连接起来,将是改变这一现状的重要机会。

假设在比特币 1.5 万亿美元市值中仅仅有 10% 流入 DeFi,生态系统中锁定的总价值 (TVL) 可能将会增加一倍以上,从而催化出前所未有的增长并实现可持续的市场动态。Lombard 认为,这种潜力可以通过安全第一的具有流动性的比特币原语—— LBTC 来释放。

比特币的现状

比特币长期以来一直被誉为“数字黄金”,是一种强大的价值存储手段和对冲通胀的工具。它的去中心化特性和安全性使其成为加密货币的“龙头”,市值超万亿美元,远远超过其他所有加密货币。然而,虽然比特币在市场上占据主导地位,但在更广泛的加密生态系统中,它的实际效用依然比较有限。与以太坊不同,比特币的架构并不容易应用于更复杂的金融应用(例如 DeFi),而其他加密货币如 USDC、USDT 和以太坊则正在 DeFi 中蓬勃发展。

比特币目前主要用于价值的持有和转移,较少用于创造收益或参与去中心化金融市场。这一局限性导致许多比特币处于闲置状态,从而错失了像以太坊等更加灵活的资产在 DeFi 领域的机会。

什么阻碍了比特币的发展?

阻碍比特币发展的一个主要因素是其简单的脚本语言。比特币的脚本不是图灵完备的,也就意味着它无法像以太坊那样支持复杂的逻辑或智能合约。虽然这种设计提高了安全性和稳定性,但同时也限制了比特币在更高级的去中心化应用程序中的功能。因此,比特币无法充分融入蓬勃发展的DeFi生态系统,而这个生态系统需要更复杂的脚本和合约功能。

另一个因素是比特币的工作量证明 (PoW) 共识机制。虽然它非常安全,但与较新的权益证明 (PoS) 系统相比,它需要更大量的资源且适应性较差。PoW 需要大量的计算能力和能源消耗,这不仅限制了其可扩展性,还限制了比特币与其他区块链生态系统的整合。PoW 的设计侧重于安全性和去中心化,却牺牲了灵活性和效率,这限制了比特币在快速发展的加密领域中的广泛实用性。

Babylon 和 Lombard 为比特币带来实用性和流动性

现在比特币巨大的经济价值可以用来确保 PoS 网络的安全。Babylon 的比特币质押主网的发布代表着一个重要的里程碑。Babylon 使比特币能够以无需信任和自我托管的方式进行质押,让 BTC 持有者能够为各种 PoS 系统的经济安全做出贡献,包括 PoS 链、第 2 层 (L2) 聚合和数据提供层。通过 Babylon 质押比特币,用户可以完全控制自己的资产,同时获得奖励并加强这些网络的安全性。直接在 Babylon 质押比特币的流动性不足,这正是 Lombard 的作用。

Lombard 的流动性比特币 LBTC 可直接与 Babylon 协议交互,让质押的比特币在 DeFi 领域保持流动性和可用性。这种整合不仅为比特币持有者释放了新的效用——使他们能够赚取收益、质押、交易和转移资产——而且还增强了 PoS 网络的安全性。通过 Babylon,Lombard 的 LBTC 弥合了比特币巨大的经济价值、安全能力与 PoS 和 DeFi 生态系统中的动态机会之间的差距,标志着比特币在去中心化经济中的变革阶段。

关于 LBTC新的比特币原语

LBTC 旨在让任何人(从个人持有者到大型机构)都能扩大其比特币的效用。它允许用户赚取原生收益、参与 DeFi 等,同时保持资产的安全性和流动性。以下是与 LBTC 相关的五个特点:

收益型比特币:使用 LBTC 解锁原生收益和奖励

如果你已经感受过 EigenLayer 等平台的好处,就会发现 LBTC 的收益能力更加引人注目。存入 Lombard 的 BTC 会被质押到 Babylon,在获得收益的同时,仍可在 DeFi 中使用。这使得 LBTC 成为一种通用产品,非常适合那些希望通过质押以低风险方式获得被动回报的比特币持有者。

无缝集成 DeFi:流动性强、用途广泛的 LBTC

LBTC 被认为是一个有潜力的 DeFi 抵押品。通过它可以用比特币与多种 DeFi 协议(如 Pendle、Morpho 和 Gearbox 等)结合使用。LBTC 旨在在保持比特币流动性的同时,使其保持生产力,从而提升资本效率。此举可能会引导比特币持有者将其资产从冷存储转移出来,参与借贷池、收益金库和交易平台,以获取潜在的额外回报。

灵活性:LBTC 的跨链可访问性

Lombard 允许用户在自己选择的网络上铸造比特币,并支持在不同生态系统之间进行无需信任的转移。借助 LBTC,比特币可以在以太坊、Solana 和 Cosmos 等多种区块链上使用,从而将每个区块链转变为比特币 DeFi 生态系统。通过使 LBTC 原生可用于多个区块链网络,Lombard 释放了比特币的潜力,减少了分散的流动性,提高了市场效率,并实现了跨生态系统的无缝移动。

安全设计:为 LBTC 提供先进保护

安全性是 LBTC 设计的重要组成部分,使其在比特币生态系统中具备较高的安全性。Lombard 与斯坦福大学及卡内基梅隆大学的密码学家共同合作,实施了符合行业标准的密钥管理和签名基础设施,从而有效应对比特币可编程性方面的挑战。Lombard 的安全联盟对协议中的每笔交易进行验证,从而增强了 LBTC 的安全性。此外,该架构通过多方审计和实时安全监控进一步强化,能够在潜在威胁出现之前进行检测和响应。

LBTC 的去中心化基础设施

Lombard 从一开始就关注构建一个尽量减少信任的基础设施。多个独立实体在 Lombard 协议上验证交易的安全联盟架构旨在降低单点故障的风险,。LBTC 的设计允许其在没有可信中介的情况下运行,从而实现透明性和社区驱动的治理。由于其无许可的特性,任何 DeFi 平台可以选择集成 LBTC,而不需要经过集中审批过程。此外,多方批准和治理决策的时间锁定机制可能有助于降低交易对手风险,维护 LBTC 在生态系统中的稳定性。

LBTC 代表了比特币生态系统中的一种创新,它的功能可能超出传统的使用方式。通过生成收益、提升流动性和支持去中心化网络,LBTC 有可能改变比特币在数字经济中的应用。与 Lombard 和 Babylon 的合作,意味着比特币可能会进入一个新的阶段,能够在去中心化金融(DeFi)领域发挥更大的作用,为未来的增长和可持续发展提供一些新机会。

LBTC 的工作原理

LBTC 流程如下:

  1. 在比特币网络上存入 BTC :用户通过 Lombard WebApp 存入其原生比特币。 可以从任何比特币地址或任何比特币钱包(包括 DeFi 钱包、硬件钱包或任何中心化交易所)进行存款。
  2. 在 Babylon 质押 BTC 存入后,Lombard 将把比特币质押到 Babylon 的安全质押基础设施中。Lombard 代表 Lombard 用户管理与 Babylon 质押相关的所有费用。
  3. 在以太坊上铸造 LBTC 质押 后,用户可以铸造与质押的 BTC 数量等值的 LBTC 代币,并将其发送到预先选择的以太坊地址。由于比特币仍质押在 Babylon,质押收益将直接计入 LBTC 代币。

LBTC 可以部署在多个区块链生态系统中,且可以在各种链上使用,例如在发布时可在以太坊上使用,甚至随着时间的推移可能会在 Solana 和 Cosmos 上使用。在不同网络上转移和使用的过程中,LBTC 将始终保持其与 BTC 1:1 支持。

总而言之,LBTC 希望通过实现收益生成、增强流动性和保护去中心化网络来改变比特币在数字经济中的使用方式。

目前,Lombard 正在实施分阶段推出的战略,以使 LBTC 在整个 DeFi 领域得到广泛使用。最初,LBTC 将在以太坊主网上推出,目前大部分比特币流动性和蓝筹协议都驻留在该主网上。此后,Lombard 计划将 LBTC 扩展到以太坊第 2 层网络,并最终扩展到创新的比特币第 2 层和下一代区块链网络。

Dan Bin's Latest Speech: Don't Miss a Great Era On June 29th, Dan Bin, Chairman of Dongfang Harbor (东方港湾), delivered a keynote speech titled "Don't Miss a Great Era" at the "2026—All in the Silicon-based New Epoch" Mid-Year Strategy Summit. Addressing concerns about an AI bubble, Dan Bin argued from an industrial cycle perspective that "the risk of missing an era may be greater than worrying about short-term bubbles." He views humanity as standing at the dawn of the AI era, which could be more disruptive than the electronics, internet, and mobile internet eras. He posits that the AI wave is unlikely to end in just three or four years. Using the internet era's decade-long rhythm as a reference point—with ChatGPT's late 2022 launch as the starting line—a key risk assessment window may only arrive around 2033. Dan Bin emphasized that technological progress is the primary driver of long-term capital market growth, while factors like trade wars or interest rate hikes are secondary. Expanding to a civilizational scale, Dan Bin presented a thought experiment on silicon-based life potentially supplementing or succeeding carbon-based life as a direction for extending Earth's civilization, especially over cosmic timescales spanning billions of years. On geopolitics, he noted that AI is already rewriting warfare rules, as seen in conflicts like Ukraine, and that neither the U.S. nor China can afford to lose the AI race, with each leveraging different strengths. Reflecting on investment lessons, Dan Bin cited Warren Buffett's and Charlie Munger's admitted "regrets" about missing major tech opportunities like Microsoft, underscoring the need for continuous cognitive evolution. His firm, Dongfang Harbor, is deepening its research in foundational AI areas like computing power and storage. Dan Bin concluded by urging investors to maintain a long-term perspective, embrace the epochal shift, and rationally hold onto the opportunities presented by this transformative age. He closed with a poetic reminder: "The tide never turns back... Born in this time is a great fortune in itself. Don't let hesitation trap your steps, nor short-sightedness waste the years—do not miss this magnificent era that belongs to us."
