Nervos Network 致力於開發 BTC Layer 2 解決方案與其 CKB 技術相一致，該技術透過保留 UTXO 功能同時允許複雜的可編程擴展來超越 BTC。 CKB 的 Cell 模型保留了比特幣的交易性質，同時融入了資料狀態，代表了持久且靈活的交易模型。 CKB 將鏈下客戶端驗證節點整合到其鏈上流程中，加速了 RGB 實施，凸顯了其作為 BTC 擴張計畫催化劑的潛力。此外，開放交易格式展示了鏈的前瞻性特徵，使參與者之間能夠協作並增強跨鏈互動能力。 Nervos 致力於完善 UTXO 模型，從比特幣閃電網路和 RGB 的整合中可以看出，這使其成為無標準 BTC Layer 2 領域的有力競爭者。
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.
當我第一次聽說 Nervos Network 致力於建造 BTC Layer 2 時，我並不感到驚訝。因為CKB公鏈技術不僅匹配而且超越了BTC。它不僅保持了BTC原生的UTXO特性，還允許更複雜的可程式擴展。雖然超越 BTC 對於 CKB 公鏈來說似乎具有挑戰性，但立志成為一流的 BTC Layer 2 似乎是個明智的選擇。為什麼？讓我們深入探討一下我對 CKB 的看法。目前的BTC Layer 2市場受到主網驗證能力有限的限制，導致替代方案多種多樣。 BTC 腳本語言的簡單性，加上其接近零的運算和驗證能力，為市場創新創造了巨大的機會。截至目前，除了 UTXO 解鎖條件下有限的交易驗證和多重簽章功能外，BTC 主網還無法直接處理涉及資料驗證、狀態變更等更複雜的交易邏輯。透過強大的公鏈實現本地共識和運算驗證能力。這導致 BTC 第 2 層解決方案缺乏統一標準或“正統”，從而使對它們進行排名變得困難。然而，可以根據社群對狹義和廣義解釋的看法進行區分：狹義地講，只有像閃電網路狀態通道和 RGB 一次性密封方法這樣的解決方案才有資格成為真正的「正統」BTC 第 2 層。他們有效地利用了 BTC 有限的腳本驗證能力，而不依賴或最低限度依賴外部局部共識。從更一般的意義上來說，任何獲得本地共識認可的擴展鏈，以及確保資產安全遷移的跨鏈橋解決方案，理論上都可以充當 BTC Layer 2。並發能力等等。顯然，BTC Layer 2 市場是分裂的：一方面是高度具體的解決方案，如緩慢發展的閃電網絡和 RGB，面臨著巨大的挑戰；另一方面，另一端是廣泛定義的解決方案，其中任何能夠與 BTC 主網安全互動的效能鏈都有資格作為 BTC 第 2 層。是的，就在於 Nervos 網絡，它堅持以 UTXO 模型為核心，增強了其效能。值得注意的特點包括： CKB 網路與 BTC 緊密結合，共享相同的“UTXO 模型和挖礦共識機制”，這與以太坊等主流公鏈的帳戶餘額模型不同。 UTXO模型在交易隱私、靈活的交易結構以及防止雙花的平行處理能力方面具有明顯的優勢，這可能是中本聰最輝煌的發明之一。這就是為什麼像 Sui 和 Aptos 這樣的後以太坊專案也採用了類似的 UTXO 模型。比特幣的容量和區塊速度可能會受到時代的限制，但 UTXO 模型卻非常具有前瞻性。 CKB 採用了這種 UTXO 模型，並將其演變成“Cell 模型”，它保留了比特幣 UTXO 模型的純粹交易性質，同時也支援以太坊等帳戶模型中的資料狀態。簡單來說：在比特幣 UTXO 模型中，硬幣的創建和銷毀類似於連續的鑄造和熔化過程。然而，Cell 模型忽略了破壞方面，專注於驗證和持久性儲存狀態。每個Cell包含容量和資料：容量以位元組為單位衡量餘額，類似於UTXO，而資料則保存任何類型的信息，包括交易狀態的歷史記錄。因此，Cell模型可以準確地表示餘額並管理資產轉移，還可以處理各種複雜的智慧合約狀態。綜上所述，Cell模型是一種更持久和靈活的交易模型，大大拓寬了UTXO模型的範圍。對於 CKB 維持 BTC 主網安全性，同時為閃電網路和 RGB 等較慢的比特幣擴張計劃提供「速度提升」的能力至關重要。例如，CKB 最近推出的 RGB++ 就說明了這一點。在BTC生態系中，開發成熟的RGB解決方案所面臨的挑戰與其說是BTC主網的一次性密封過程，不如說是鏈下客戶端驗證節點之間的通訊、協調和相互狀態維護，特別是在分散的設定。簡單來說，RGB 的理論可能看起來很簡單，但其實際實施卻受到基礎設施限制和各種障礙的阻礙。
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.

認識到這一點，CKB 將這些鏈下客戶端驗證節點整合到其鏈上公共驗證流程中。這種方法顯著加速了 RGB 旨在實現的預期 UTXO 用戶端擴充路徑。鏈下節點之間複雜的 P2P 共識極具挑戰性，充滿複雜性和障礙，例如潛在的資料同步延遲或不一致，以及容易受到詐欺和攻擊。將此過程轉移到區塊鏈上可以簡化這些問題。隨著圍繞 RGB++ 的討論越來越多，我們也來看看 CKB 的 Open Transaction 資料格式，展示了該鏈的前瞻性特徵。開放交易允許多個參與者隨著時間的推移協作建立和聚合不同的交易。它支援部分建置、可修改性以及增量建置和聚合。例如，Alice發起一筆Open Transaction，與Bob用一定數量的Token A交換Token B。事務一旦啟動，就保持可編輯狀態。 Bob 在同意交易條款後，可以添加他的代幣 B 並最終確定條件。乍一看它可能看起來很抽象。以跨鏈場景為例：Alice 和 Bob 可以獨立執行不同鏈上的資產交易，大大提升了 CKB 鏈的跨鏈互動能力。在複雜的 DeFi 交易領域，往往需要市場驅動的動態調整，Open Transaction 允許合約參與者在合約執行過程中流暢地調整交易條件。這無疑增強了管理交易複雜性的能力。在我看來，Open Transaction 反映了 UTXO 交易的解鎖條件，能夠融合複雜的解鎖條件、多方簽名和複雜的交易環境。這代表了一種基於 BTC 主鏈基本原則的進化且有價值的創新。有趣的是，以太坊團隊的核心開發人員 Jan Xie 在他的第一個重大專案中選擇了採用 BTC UTXO 模型。儘管以太坊的智慧合約模型得到了更廣泛的應用，Jan 和他的 Nervos 團隊果斷選擇擴展和完善 BTC UTXO 模型。這個選擇體現了對中本聰簡化UTXO 交易模型的深深尊重，也巧妙地為其轉型為原生BTC Layer 2 奠定了基礎。看，它當然有潛力加快基於 UTXO 的鏈中閃電網路和 RGB 等項目的實施，為 BTC 主網上的這些「正統」擴展解決方案提供寶貴的見解。從長遠來看，CKB 鏈的固有特性及其創新的架構相容性可能使其能夠在 BTC Layer 2 複雜且無標準的領域中脫穎而出。注意：關於 CKB 的技術細微差別和突出功能，還有很多值得探索的地方，我計劃稍後更深入地分析。令人著迷的是，BTC Layer 2 不僅為新鏈的崛起提供了平台，而且還為現有鏈的復興開闢了無限的可能性。作者：昊天，獨立研究員本文是昊天推文的翻譯。當我第一次聽說 Nervos Network 致力於建造 BTC Layer 2 時，我並不感到驚訝。因為CKB公鏈技術不僅匹配而且超越了BTC。它不僅保持了BTC原生的UTXO特性，還允許更複雜的可程式擴展。雖然超越 BTC 對於 CKB 公鏈來說似乎具有挑戰性，但立志成為一流的 BTC Layer 2 似乎是個明智的選擇。為什麼？讓我們深入探討一下我對 CKB 的看法。 BTC 目前的 BTC Layer 2 市場受到主網驗證能力有限的限制，導致替代方案多種多樣。 BTC 腳本語言的簡單性，加上其接近零的運算和驗證能力，為市場創新創造了巨大的機會。截至目前，除了 UTXO 解鎖條件下有限的交易驗證和多重簽章功能外，BTC 主網還無法直接處理涉及資料驗證、狀態變更等更複雜的交易邏輯。透過強大的公鏈實現本地共識和運算驗證能力。這導致 BTC 第 2 層解決方案缺乏統一標準或“正統”，從而使對它們進行排名變得困難。然而，可以根據社區對狹義和廣義解釋的看法進行區分： 然而，可以根據社區對狹義和廣義解釋的看法進行區分： 狹義定義，只有像閃電網絡狀態通道和一次性解決方案這樣的解決方案RGB 的密封方法堪稱真正的「正統」BTC Layer 2。他們有效地利用了 BTC 有限的腳本驗證能力，而不依賴或最低限度依賴外部局部共識。從更一般的意義上來說，任何獲得本地共識認可的擴展鏈，以及確保資產安全遷移的跨鏈橋解決方案，理論上都可以充當 BTC Layer 2。並發能力等等。顯然，BTC Layer 2 市場是分裂的：一方面是高度具體的解決方案，如緩慢發展的閃電網絡和 RGB，面臨著巨大的挑戰；另一方面，另一端是廣泛定義的解決方案，其中任何能夠與 BTC 主網安全交互的性能鏈都有資格作為 BTC Layer 2。是的，就在於 Nervos 網絡，它堅持以 UTXO 模型為核心，增強了其效能。值得注意的特點包括： CKB 網路與 BTC 緊密結合，共享相同的“UTXO 模型和挖礦共識機制”，這與以太坊等主流公鏈的帳戶餘額模型不同。 UTXO模型在交易隱私、靈活的交易結構以及防止雙花的平行處理能力方面具有明顯的優勢，這可能是中本聰最輝煌的發明之一。這就是為什麼像 Sui 和 Aptos 這樣的後以太坊專案也採用了類似的 UTXO 模型。比特幣的容量和區塊速度可能會受到時代的限制，但 UTXO 模型卻非常具有前瞻性。 CKB 採用了這種 UTXO 模型，並將其演變成“Cell 模型”，它保留了比特幣 UTXO 模型的純粹交易性質，同時也支援以太坊等帳戶模型中的資料狀態。簡單來說：在比特幣 UTXO 模型中，硬幣的創建和銷毀類似於連續的鑄造和熔化過程。然而，Cell 模型忽略了破壞方面，專注於驗證和持久性儲存狀態。每個Cell包含容量和資料：容量以位元組為單位衡量餘額，類似於UTXO，而資料則保存任何類型的信息，包括交易狀態的歷史記錄。因此，Cell模型可以準確地表示餘額並管理資產轉移，還可以處理各種複雜的智慧合約狀態。簡單來說，Cell模型是一種更持久和靈活的交易模型，大大拓寬了UTXO模型的範圍。對於 CKB 維持 BTC 主網安全性，同時為閃電網路和 RGB 等較慢的比特幣擴張計劃提供「速度提升」的能力至關重要。例如，CKB 最近推出的 RGB++ 就說明了這一點。在BTC生態系中，開發成熟的RGB解決方案所面臨的挑戰與其說是BTC主網的一次性密封過程，不如說是鏈下客戶端驗證節點之間的通訊、協調和相互狀態維護，特別是在分散的設定。簡單來說，RGB 的理論可能看起來很簡單，但其實際實施卻受到基礎設施限制和各種障礙的阻礙。
