使用BITVMX升級比特幣的智能合同功能

BITVMX代表了比特幣的智能合同能力的重大升級，實現通用計算和支持高級應用程序

In the constantly evolving landscape of cryptocurrency, Bitcoin has emerged as a dominant force, renowned for its robust security and vast user base. However, despite being the first cryptocurrency, Bitcoin's lack of smart contract capabilities has been a subject of discussion. In contrast, Ethereum, the second-largest cryptocurrency, is widely recognized for its advanced smart contract technology, which forms the foundation for diverse decentralized applications (DApps).

在不斷發展的加密貨幣景觀中，比特幣以其強大的安全性和龐大的用戶群而聞名，比特幣成為了主導力量。但是，儘管是第一次加密貨幣，但比特幣缺乏智能合同功能一直是討論的主題。相比之下，以太坊是第二大加密貨幣，以其先進的智能合同技術而廣受認可，該技術構成了分散應用程序（DAPPS）的基礎。

Now, in a significant development, BitVMX, an upgrade to the BitVM programming environment, is poised to introduce general-purpose computation to Bitcoin's base layer, adjusting the virtual CPU model and introducing support for zero-knowledge SNARK proofs. This upgrade, which does not alter the consensus protocol, expands Bitcoin's programmability to levels comparable to Ethereum, opening up a new chapter in cryptocurrency innovation.

現在，在重大的開發中，BITVMX是對BITVM編程環境的升級，有望將通用計算引入比特幣的基礎層，調整虛擬CPU模型，並引入對零知識的Snark證明的支持。此升級不會改變共識協議，將比特幣的可編程性擴展到與以太坊相當的級別，開闢了加密貨幣創新的新章節。

As reported by blog.bitfinex.com, BitVMX, an upgrade to the BitVM programming environment, is bringing general-purpose computation to Bitcoin's base layer without any changes to the consensus protocol.

正如Blog.bitfinex.com報導的那樣，BITVMX是對BITVM編程環境的升級，正在將通用計算帶到比特幣的基礎層，而無需對共識協議進行任何更改。

This upgrade to the programming environment developed by the Rootstock team introduces a virtual CPU model that can execute and verify complex programs, including SNARK proofs, through an optimistic verification method. It builds on the original BitVM, which was designed to introduce smart contract-like functionality to Bitcoin without modifying the consensus protocol.

Rootstock團隊開發的編程環境的升級是引入了一個虛擬CPU模型，該模型可以通過樂觀的驗證方法執行和驗證複雜程序（包括Snark證明）。它建立在原始的BITVM上，該BITVM旨在將類似於智能合約的功能引入比特幣，而無需修改共識協議。

Can execute and verify programs up to 100K in assembly code.

可以在彙編代碼中執行和驗證多達100K的程序。

“This allows for the verification of SNARK proofs directly on Bitcoin, enhancing privacy-preserving applications and trust-minimized systems. Developers can compile ZK proof verifiers into BitVMX-compatible code for on-chain verification, significantly expanding the potential for privacy tools and scalable rollups.”

“這允許直接在比特幣上驗證SNARK證明，從而增強隱私保護應用程序和信任最小化的系統。開發人員可以將ZK證明驗證器編譯為與BITVMX兼容的代碼，以進行鏈驗證，從而顯著擴展了潛在的隱私工具和可擴展的匯總和可擴展的匯總。”

What Can BitVMX Add to Bitcoin’s Smart Contract Ecosystem?

BITVMX可以添加到比特幣的智能合同生態系統中？

The BitVMX upgrade for the Rootstock Bitcoin sidechain marks a significant step forward in enhancing Bitcoin’s programmability. By enabling the execution and verification of complex computations like zero-knowledge SNARK proofs, BitVMX facilitates a more advanced blockchain application environment. The upgrade utilizes a virtual CPU model that supports general-purpose computation through architectures like RISC-V. This approach allows computations to be challenged only when necessary, minimizing the on-chain load and enhancing scalability without risking Bitcoin’s base layer.

BitVMX's challenge-response protocol uses hash chains to validate execution traces, simplifying the verification process and reducing computational overhead. This innovation makes it feasible to build rollups and sidechains on Bitcoin, with message linking using one-time signature schemes ensuring state preservation across transactions. This design enables the creation of Bitcoin-based systems with flexibility comparable to Ethereum, varying the rollup and sidechain technology used based on application needs.

BITVMX的挑戰響應協議使用哈希鏈來驗證執行跟踪，簡化驗證過程並減少計算開銷。這項創新使在比特幣上構建匯總和側鏈機構可行，並使用一次性簽名方案鏈接消息，以確保跨交易中的狀態保存。該設計使創建基於比特幣的系統具有與以太坊相當的靈活性，從而根據應用需求改變了使用的匯總和Sidechain技術。

However, despite the potential of smart contracts, their integration into Bitcoin has been a gradual process due to the cryptocurrency's decentralized nature. Any changes to Bitcoin's scripting language require consensus among a large majority of nodes, which can be a slow and complex procedure.

但是，儘管有智能合約的潛力，但由於加密貨幣的分散性質，它們與比特幣的集成一直是一個逐步的過程。對比特幣腳本語言的任何更改都需要在大多數節點之間達成共識，這可能是一個緩慢而復雜的過程。

To overcome this challenge, BitVMX maintains compatibility with Bitcoin's existing scripting language, allowing for the incremental introduction of new capabilities. Moreover, BitVMX's modular architecture enables developers to select and combine components as needed, fostering an ecosystem of specialized applications.

為了克服這一挑戰，BITVMX保持與比特幣現有的腳本語言的兼容性，從而可以增量引入新功能。此外，BITVMX的模塊化體系結構使開發人員能夠根據需要選擇和組合組件，從而促進專用應用程序的生態系統。

What Kind of Additional Programmability or Capabilities Can BitVMX Users Expect?

BITVMX用戶期望有哪些其他其他可編程性或功能？

Expanding on Bitcoin's programmability, BitVMX introduces smart contract-like functionality without altering core consensus rules. This allows for the verification of zero-knowledge proofs directly on Bitcoin, enhancing privacy-preserving applications and trust-minimized systems. Developers can compile ZK proof verifiers into BitVMX-compatible code for on-chain verification, significantly expanding the potential for privacy tools and scalable rollups.

BITVMX擴展了比特幣的可編程性，在不更改核心共識規則的情況下引入了類似智能合約的功能。這允許直接在比特幣上驗證零知識證明，從而增強了隱私保護應用程序和信任最少的系統。開發人員可以將ZK證明驗證器編譯到與BITVMX兼容的代碼中，以進行鏈上驗證，從而大大擴展了隱私工具和可擴展匯總的潛力。

Additionally, BitVMX enables the creation of decentralized bridges and sidechain communication mechanisms. Rootstock plans to develop the “Union Bridge” using BitVMX to create a trust-minimized bridge between Bitcoin and the Rootstock sidechain. This facilitates seamless asset transfers and multi-chain applications while preserving Bitcoin's decentralization.

此外，BITVMX可以創建分散的橋樑和側chain的通信機制。 Rootstock計劃使用BITVMX開發“聯合橋”，以在比特幣和砧木Sidechain之間創建一個信任最小的橋樑。這有助於無縫資產轉移和多鏈應用，同時保留比特幣的權力下放。

Overall, BitVMX transforms Bitcoin from sound money into a broader computational substrate, encouraging an ecosystem of experimentation and specialization. Its modular architecture supports a wide array of advanced DApps, from complex financial contracts to decentralized oracles, all within Bitcoin's secure and decentralized framework.

總體而言，BITVMX將比特幣從聲音貨幣轉變為更廣泛的計算基板，鼓勵了實驗和專業化的生態系統。它的模塊化體系結構支持各種高級DAPP，從復雜的金融合同到分散的甲殼，都在比特幣的安全和分散的框架內。
