Nervos Network 致力于开发 BTC Layer 2 解决方案与其 CKB 技术相一致，该技术通过保留 UTXO 功能同时允许复杂的可编程扩展来超越 BTC。 CKB 的 Cell 模型保留了比特币的交易性质，同时融入了数据状态，代表了持久且灵活的交易模型。 CKB 将链下客户端验证节点集成到其链上流程中，加速了 RGB 实施，凸显了其作为 BTC 扩张计划催化剂的潜力。此外，开放交易格式展示了链的前瞻性特征，使参与者之间能够协作并增强跨链交互能力。 Nervos 致力于完善 UTXO 模型，从比特币闪电网络和 RGB 的集成中可以看出，这使其成为无标准 BTC Layer 2 领域的有力竞争者。
When I first heard about Nervos Network's dedication to building a BTC Layer 2, I wasn't surprised. That's because the CKB public blockchain technology not only matches but also goes beyond BTC. It not only maintains BTC's native UTXO features but also allows for more complex programmable extensions. While surpassing BTC may seem challenging for CKB public chain, aiming to be a top-notch BTC Layer 2 seems like a smart choice. Why? Let's delve into my take on CKB. The current BTC Layer 2 market is constrained by the mainnet’s limited validation capabilities, resulting in diverse alternative solutions. The simplicity of BTC's scripting language, combined with its near-zero computation and validation power, has created significant opportunities for market innovation. As of now, aside from limited transaction validation and multisig functionalities within UTXO unlocking conditions, the BTC mainnet is incapable of directly handling more complex transaction logic involving data validation, state changes, etc. It relegates BTC to an asset settlement layer, relying on extending through a powerful public chain for local consensus and computational validation capabilities. This leads to a lack of uniform standards or 'orthodoxy' for BTC Layer 2 solutions, making it challenging to rank them. However, distinctions can be made based on the community's perception between narrow and broad interpretations: Narrowly defined, only solutions like the Lightning Network state channels and the one-time seal approach of RGB qualify as truly 'orthodox' BTC Layer 2s. They effectively utilize BTC's limited script validation capacity without relying on or minimally depending on external local consensus. In a more general sense, any extension chain that gains acceptance for its local consensus, along with a cross-chain bridge solution that ensures the safe migration of assets, can theoretically serve as a BTC Layer 2. This includes contemporary Ethereum EVM chains, Solana with its high-concurrency capabilities, and others. Clearly, the BTC Layer 2 market is divided: on one end are highly-specific solutions like the slowly evolving Lightning Network and RGB, facing substantial challenges; on the other end are broadly defined solutions, where any performance chain capable of securely interacting with the BTC mainnet qualifies as a BTC Layer 2. But is there a 'middle-of-the-road' option? Yes, and it lies in the Nervos Network, which adheres to the UTXO model at its core, enhancing its performance. Notable features include: The CKB Network aligns closely with BTC, sharing the same 'UTXO model and mining consensus mechanism,' unlike the account balance model of mainstream public blockchains like Ethereum. The UTXO model has distinct advantages in transaction privacy, flexible transaction structuring, and parallel processing capabilities to prevent double-spending, which may be one of Satoshi Nakamoto’s most brilliant inventions. This is why post-Ethereum projects like Sui and Aptos have also adopted similar UTXO models. Bitcoin's capacity and block speed may be constrained by its era, but the UTXO model is remarkably forward-thinking. CKB adopts this UTXO model, evolving it into the 'Cell model', which preserves the pure transactional nature of Bitcoin’s UTXO model while also supporting the data states found in account models like Ethereum’s. To simplify: In the Bitcoin UTXO model, the creation and destruction of coins resemble a continuous minting and melting process. The Cell model, however, omits the destruction aspect, focusing on verifying and persistently storing states. Each Cell includes Capacity and Data: Capacity measures the balance in bytes, similar to UTXO, while Data holds any kind of information, including the history of transaction states. Thus, the Cell model can accurately represent balances and manage asset transfers, and also handle a variety of complex smart contract states. In summary, the Cell model is a more persistent and flexible transaction model that greatly broadens the scope of the UTXO model. It is crucial for CKB’s ability to maintain the security of the BTC mainnet while offering a 'speed boost' to slower Bitcoin expansion initiatives like the Lightning Network and RGB. For instance, the recent rollout of RGB++ by CKB illustrates this. In the BTC ecosystem, developing a mature RGB solution involves challenges that are not so much about the one-time sealing process of the BTC mainnet, but rather the communication, coordination, and mutual state maintenance among off-chain client validation nodes, particularly in a decentralized setting. In simpler terms, RGB's theory might seem straightforward, but its practical implementation is hindered by foundational infrastructural limitations and various barriers.
当我第一次听说 Nervos Network 致力于构建 BTC Layer 2 时，我并不感到惊讶。因为CKB公链技术不仅匹配而且超越了BTC。它不仅保持了BTC原生的UTXO特性，还允许更复杂的可编程扩展。虽然超越 BTC 对于 CKB 公链来说似乎具有挑战性，但立志成为一流的 BTC Layer 2 似乎是一个明智的选择。为什么？让我们深入探讨一下我对 CKB 的看法。目前的BTC Layer 2市场受到主网验证能力有限的限制，导致替代方案多种多样。 BTC 脚本语言的简单性，加上其接近于零的计算和验证能力，为市场创新创造了巨大的机会。截至目前，除了 UTXO 解锁条件下有限的交易验证和多重签名功能外，BTC 主网还无法直接处理涉及数据验证、状态更改等更复杂的交易逻辑。它将 BTC 降级为资产结算层，依赖于扩展通过强大的公链实现本地共识和计算验证能力。这导致 BTC 第 2 层解决方案缺乏统一标准或“正统”，从而使对它们进行排名变得困难。然而，可以根据社区对狭义和广义解释的看法进行区分：狭义地讲，只有像闪电网络状态通道和 RGB 一次性密封方法这样的解决方案才有资格成为真正的“正统”BTC 第 2 层。他们有效地利用了 BTC 有限的脚本验证能力，而不依赖或最低限度依赖外部局部共识。从更一般的意义上来说，任何获得本地共识认可的扩展链，以及确保资产安全迁移的跨链桥解决方案，理论上都可以充当 BTC Layer 2。这包括当代的以太坊 EVM 链、Solana其高并发能力等等。显然，BTC Layer 2 市场是分裂的：一方面是高度具体的解决方案，如缓慢发展的闪电网络和 RGB，面临着巨大的挑战；另一方面，另一端是广泛定义的解决方案，其中任何能够与 BTC 主网安全交互的性能链都有资格作为 BTC 第 2 层。但是是否有“中间道路”选项呢？是的，就在于 Nervos 网络，它坚持以 UTXO 模型为核心，增强了其性能。值得注意的特点包括： CKB 网络与 BTC 紧密结合，共享相同的“UTXO 模型和挖矿共识机制”，这与以太坊等主流公链的账户余额模型不同。 UTXO模型在交易隐私、灵活的交易结构以及防止双花的并行处理能力方面具有明显的优势，这可能是中本聪最辉煌的发明之一。这就是为什么像 Sui 和 Aptos 这样的后以太坊项目也采用了类似的 UTXO 模型。比特币的容量和区块速度可能会受到时代的限制，但 UTXO 模型却非常具有前瞻性。 CKB 采用了这种 UTXO 模型，并将其演变成“Cell 模型”，它保留了比特币 UTXO 模型的纯粹交易性质，同时也支持以太坊等账户模型中的数据状态。简单来说：在比特币 UTXO 模型中，硬币的创建和销毁类似于连续的铸造和熔化过程。然而，Cell 模型忽略了破坏方面，专注于验证和持久存储状态。每个Cell包括容量和数据：容量以字节为单位衡量余额，类似于UTXO，而数据则保存任何类型的信息，包括交易状态的历史记录。因此，Cell模型可以准确地表示余额并管理资产转移，还可以处理各种复杂的智能合约状态。综上所述，Cell模型是一种更加持久和灵活的交易模型，极大地拓宽了UTXO模型的范围。对于 CKB 维持 BTC 主网安全性，同时为闪电网络和 RGB 等较慢的比特币扩张计划提供“速度提升”的能力至关重要。例如，CKB 最近推出的 RGB++ 就说明了这一点。在BTC生态系统中，开发成熟的RGB解决方案所面临的挑战与其说是BTC主网的一次性密封过程，不如说是链下客户端验证节点之间的通信、协调和相互状态维护，特别是在分散的设置。简单来说，RGB 的理论可能看起来很简单，但其实际实施却受到基础设施限制和各种障碍的阻碍。
Recognizing this, CKB integrates these off-chain client validation nodes into its on-chain public validation process. This approach significantly accelerates the intended UTXO client extension pathway that RGB aims to achieve. Complex P2P consensus among off-chain nodes is notoriously challenging, fraught with complexity and obstacles such as potential data synchronization delays or inconsistencies, and susceptibility to fraud and attacks. Transposing this process onto the blockchain can simplify these issues. With the increasing discussions around RGB++, let’s also look at CKB's Open Transaction data format, showcasing the chain's forward-thinking features. Open Transaction allows multiple participants to collaboratively build and aggregate different transactions over time. It supports partial construction, amendability, and incremental build-up and aggregation. For example, Alice initiates an Open Transaction to exchange a certain amount of Token A for Token B with Bob. The transaction, once started, remains in an editable state. Bob, upon agreeing to the transaction terms, can then add his Token B and finalize the conditions. It might initially seem abstract. Take cross-chain scenarios as an example: Alice and Bob could independently execute asset trades on various distinct chains, significantly boosting the CKB chain's cross-chain interaction capabilities. In the realm of complex DeFi transactions, where market-driven dynamic adjustments are often necessary, Open Transaction allows contract participants to adapt trading conditions fluidly during the contract's execution. This undoubtedly enhances the ability to manage transactional complexities. From my perspective, Open Transaction mirrors the UTXO transaction unlocking conditions, capable of amalgamating intricate unlocking conditions, multi-party signatures, and complex transactional environments. This represents an evolutionary and valuable innovation that builds on the foundational principles of the BTC main chain. Interestingly, Jan Xie, a core developer from the Ethereum team, chose to embrace the BTC UTXO model for his inaugural major project. Despite the broader application of Ethereum's smart contract model, Jan and his Nervos team decisively chose to expand and refine the BTC UTXO model. This choice reflects a deep respect for Satoshi Nakamoto’s simplistic UTXO transaction model and also subtly lays the groundwork for its transformation into a native BTC Layer 2. In conclusion, I am quite bullish about CKB’s potential as a BTC Layer 2. In the short term, it certainly has the potential to expedite the implementation of projects like the Lightning Network and RGB within UTXO-based chains, offering valuable insights for these 'orthodox' expansion solutions on the BTC mainnet. Looking long-term, the inherent features of CKB's chain and its innovative architectural compatibility may enable it to excel in the complex and standardless arena of BTC Layer 2s. Note: There’s much more to explore regarding the technical nuances and standout features of CKB, which I plan to analyze in greater depth later. It's fascinating to see how BTC Layer 2 not only provides a platform for new chains to rise but also opens up endless possibilities for rejuvenation within established chains.

认识到这一点，CKB 将这些链下客户端验证节点集成到其链上公共验证流程中。这种方法显着加速了 RGB 旨在实现的预期 UTXO 客户端扩展路径。链下节点之间复杂的 P2P 共识极具挑战性，充满复杂性和障碍，例如潜在的数据同步延迟或不一致，以及容易受到欺诈和攻击。将此过程转移到区块链上可以简化这些问题。随着围绕 RGB++ 的讨论越来越多，我们也来看看 CKB 的 Open Transaction 数据格式，展示了该链的前瞻性特征。开放交易允许多个参与者随着时间的推移协作构建和聚合不同的交易。它支持部分构建、可修改性以及增量构建和聚合。例如，Alice发起一笔Open Transaction，与Bob用一定数量的Token A交换Token B。事务一旦启动，就保持可编辑状态。 Bob 在同意交易条款后，可以添加他的代币 B 并最终确定条件。乍一看它可能看起来很抽象。以跨链场景为例：Alice 和 Bob 可以独立执行不同链上的资产交易，极大提升了 CKB 链的跨链交互能力。在复杂的 DeFi 交易领域，往往需要市场驱动的动态调整，Open Transaction 允许合约参与者在合约执行过程中流畅地调整交易条件。这无疑增强了管理交易复杂性的能力。在我看来，Open Transaction 反映了 UTXO 交易的解锁条件，能够融合复杂的解锁条件、多方签名和复杂的交易环境。这代表了一种基于 BTC 主链基本原则的进化且有价值的创新。有趣的是，以太坊团队的核心开发人员 Jan Xie 在他的第一个重大项目中选择了采用 BTC UTXO 模型。尽管以太坊的智能合约模型得到了更广泛的应用，Jan 和他的 Nervos 团队果断选择扩展和完善 BTC UTXO 模型。这一选择体现了对中本聪简单化 UTXO 交易模型的深深尊重，也巧妙地为其转型为原生 BTC Layer 2 奠定了基础。总而言之，我非常看好 CKB 作为 BTC Layer 2 的潜力。从短期来看，它当然有潜力加快基于 UTXO 的链中闪电网络和 RGB 等项目的实施，为 BTC 主网上的这些“正统”扩展解决方案提供宝贵的见解。从长远来看，CKB 链的固有特性及其创新的架构兼容性可能使其能够在 BTC Layer 2 复杂且无标准的领域中脱颖而出。注意：关于 CKB 的技术细微差别和突出功能，还有很多值得探索的地方，我计划稍后更深入地分析。令人着迷的是，BTC Layer 2 不仅为新链的崛起提供了平台，而且还为现有链的复兴开辟了无限的可能性。作者：昊天，独立研究员本文是昊天推文的翻译。当我第一次听说 Nervos Network 致力于构建 BTC Layer 2 时，我并不感到惊讶。因为CKB公链技术不仅匹配而且超越了BTC。它不仅保持了BTC原生的UTXO特性，还允许更复杂的可编程扩展。虽然超越 BTC 对于 CKB 公链来说似乎具有挑战性，但立志成为一流的 BTC Layer 2 似乎是一个明智的选择。为什么？让我们深入探讨一下我对 CKB 的看法。 BTC 目前的 BTC Layer 2 市场受到主网验证能力有限的限制，导致替代方案多种多样。 BTC 脚本语言的简单性，加上其接近于零的计算和验证能力，为市场创新创造了巨大的机会。截至目前，除了 UTXO 解锁条件下有限的交易验证和多重签名功能外，BTC 主网还无法直接处理涉及数据验证、状态更改等更复杂的交易逻辑。它将 BTC 降级为资产结算层，依赖于扩展通过强大的公链实现本地共识和计算验证能力。这导致 BTC 第 2 层解决方案缺乏统一标准或“正统”，从而使对它们进行排名变得困难。然而，可以根据社区对狭义和广义解释的看法进行区分： 然而，可以根据社区对狭义和广义解释的看法进行区分： 狭义定义，只有像闪电网络状态通道和一次性解决方案这样的解决方案RGB 的密封方法堪称真正的“正统”BTC Layer 2。他们有效地利用了 BTC 有限的脚本验证能力，而不依赖或最低限度依赖外部局部共识。从更一般的意义上来说，任何获得本地共识认可的扩展链，以及确保资产安全迁移的跨链桥解决方案，理论上都可以充当 BTC Layer 2。这包括当代的以太坊 EVM 链、Solana其高并发能力等等。显然，BTC Layer 2 市场是分裂的：一方面是高度具体的解决方案，如缓慢发展的闪电网络和 RGB，面临着巨大的挑战；另一方面，另一端是广泛定义的解决方案，其中任何能够与 BTC 主网安全交互的性能链都有资格作为 BTC Layer 2。显然，BTC Layer 2 市场是分裂的：但是是否存在“中间道路” ' 选项？是的，就在于 Nervos 网络，它坚持以 UTXO 模型为核心，增强了其性能。值得注意的特点包括： CKB 网络与 BTC 紧密结合，共享相同的“UTXO 模型和挖矿共识机制”，这与以太坊等主流公链的账户余额模型不同。 UTXO模型在交易隐私、灵活的交易结构以及防止双花的并行处理能力方面具有明显的优势，这可能是中本聪最辉煌的发明之一。这就是为什么像 Sui 和 Aptos 这样的后以太坊项目也采用了类似的 UTXO 模型。比特币的容量和区块速度可能会受到时代的限制，但 UTXO 模型却非常具有前瞻性。 CKB 采用了这种 UTXO 模型，并将其演变成“Cell 模型”，它保留了比特币 UTXO 模型的纯粹交易性质，同时也支持以太坊等账户模型中的数据状态。简单来说：在比特币 UTXO 模型中，硬币的创建和销毁类似于连续的铸造和熔化过程。然而，Cell 模型忽略了破坏方面，专注于验证和持久存储状态。每个Cell包括容量和数据：容量以字节为单位衡量余额，类似于UTXO，而数据则保存任何类型的信息，包括交易状态的历史记录。因此，Cell模型可以准确地表示余额并管理资产转移，还可以处理各种复杂的智能合约状态。简单来说，Cell模型是一种更加持久和灵活的交易模型，极大地拓宽了UTXO模型的范围。对于 CKB 维持 BTC 主网安全性，同时为闪电网络和 RGB 等较慢的比特币扩张计划提供“速度提升”的能力至关重要。例如，CKB 最近推出的 RGB++ 就说明了这一点。在BTC生态系统中，开发成熟的RGB解决方案所面临的挑战与其说是BTC主网的一次性密封过程，不如说是链下客户端验证节点之间的通信、协调和相互状态维护，特别是在分散的设置。简单来说，RGB 的理论可能看起来很简单，但其实际实施却受到基础设施限制和各种障碍的阻碍。
