比特幣總結：革命性的典範轉移釋放了可擴展性和圖靈完備性

一個加密貨幣開發團隊提出了一個新框架，可以在比特幣區塊鏈上實現交易匯總，此舉可能會將智慧合約、DeFi 和其他應用程式引入世界上最古老的加密貨幣中。該框架名為 BitSNARK，使用 ZK 證明和質詢回應序列來驗證交易，類似於樂觀匯總。

Bitcoin Rollups: A Revolutionary Paradigm Shift

比特幣總結：革命性的典範轉移

Introduction

介紹

The world of cryptocurrency has witnessed a remarkable breakthrough with the emergence of a groundbreaking plan to introduce transaction rollups on Bitcoin. This revolutionary concept, once deemed an impossibility on the revered blockchain, has the potential to unleash a transformative wave of innovation and expand Bitcoin's capabilities beyond its current boundaries.

隨著在比特幣上引入交易匯總的突破性計劃的出現，加密貨幣世界見證了顯著的突破。這個革命性的概念曾經被認為在受人尊敬的區塊鏈上是不可能實現的，但它有可能引發變革性的創新浪潮，並將比特幣的功能擴展到其當前的邊界之外。

The Promise of Rollups: Scaling and Enhanced Functionality

Rollups 的前景：擴展和增強功能

Rollups, a decentralized mechanism for bundling crypto transactions off-chain and then settling them on-chain in more efficient batches, have historically been employed as a scaling solution for Ethereum. However, the creators of the proposed Bitcoin rollup framework, known as BitSNARK and Grail, envision a far more comprehensive role for this technology. They assert that rollups will not only enhance Bitcoin's capacity but also introduce full Turing complete functionality.

Rollups 是一種去中心化機制，用於在鏈外捆綁加密交易，然後以更高效的方式在鏈上進行結算，歷史上一直被用作以太坊的擴展解決方案。然而，擬議的比特幣匯總框架（稱為 BitSNARK 和 Grail）的創建者預計該技術將發揮更全面的作用。他們斷言，匯總不僅會增強比特幣的容量，還會引入完整的圖靈完備功能。

Turing completeness, a fundamental concept in computer science, implies that Bitcoin will gain the ability to execute smart contracts. This opens up the possibility of deploying decentralized finance (DeFi) applications and a wide array of other functionalities currently unavailable on Bitcoin.

圖靈完備性是電腦科學的基本概念，意味著比特幣將獲得執行智慧合約的能力。這為部署去中心化金融（DeFi）應用程式以及目前比特幣上不可用的各種其他功能提供了可能性。

BitSNARK and Grail: Laying the Foundation for Bitcoin Rollups

BitSNARK 和 Grail：為比特幣 Rollup 奠定基礎

The proposed Bitcoin rollup framework consists of two key innovations: BitSNARK and Grail. BitSNARK is a software library specifically tailored for verifying zkSNARKs on Bitcoin. zkSNARKs, or zero-knowledge succinct non-interactive arguments of knowledge, are cryptographic proofs that enable the verification of completed transactions without revealing any additional details.

擬議的比特幣匯總框架由兩項關鍵創新組成：BitSNARK 和 Grail。 BitSNARK 是一個專門用於驗證比特幣上的 zkSNARK 的軟體庫。 zkSNARK（零知識簡潔非互動式知識論證）是加密證明，可以驗證已完成的交易，而無需透露任何其他細節。

Grail, built upon the foundation of BitSNARK, serves as a practical and scalable implementation for creating a Bitcoin rollup bridge. The Grail bridge will empower users to seamlessly transfer BTC and other assets between layer-2 networks and the Bitcoin blockchain in a near trustless environment.

Grail 建立在 BitSNARK 的基礎上，是創建比特幣匯總橋的實用且可擴展的實作。 Grail 橋將使用戶能夠在近乎無信任的環境中在第 2 層網路和比特幣區塊鏈之間無縫轉移 BTC 和其他資產。

Combining Elements of ZK and Optimistic Rollups

結合 ZK 和 Optimistic Rollups 的元素

According to Edan Yago, a co-author of the BitSNARK and Grail framework, Bitcoin rollups possess unique characteristics that differentiate them from both ZK and optimistic rollups on Ethereum.

BitSNARK 和 Grail 框架的合著者 Edan Yago 表示，比特幣 Rollup 具有獨特的特徵，使其與以太坊上的 ZK 和 Optimistic Rollup 區分開來。

"Bitcoin rollups leverage ZK proofs for verification, but they employ a challenge-response sequence that resembles optimistic rollups in certain aspects," Yago explains.

「比特幣匯總利用 ZK 證明進行驗證，但它們採用了在某些方面類似於樂觀匯總的挑戰-響應序列，」Yago 解釋道。

Intermediary Operators: Ensuring Security and Integrity

中介業者：確保安全和誠信

While the BitcoinOS system eliminates the need for soft or hard fork upgrades to Bitcoin Core, it relies on intermediary agents known as "operators" to facilitate bridge deposits and withdrawals. These operators maintain constant monitoring of each other's activities, preventing malicious actors from stealing user funds or executing fraudulent transactions.

雖然BitcoinOS系統消除了對Bitcoin Core進行軟或硬分叉升級的需要，但它依賴於被稱為「運營商」的中介機構來促進橋樑存款和提款。這些業者持續監控彼此的活動，防止惡意行為者竊取用戶資金或執行詐欺交易。

Yago emphasizes the system's resilience, stating, "As long as even a single operator remains honest, the system's integrity is preserved."

Yago 強調了系統的彈性，並表示：“只要單個操作員保持誠實，系統的完整性就可以保持。”

Decentralized Governance and Scalability

去中心化治理和可擴展性

The proposed rollup system features a decentralized governance model with "no theoretical limit to the number of participants." New operators can join and leave the network by adhering to established procedures. Sovryn, a Bitcoin DeFi platform, aims to create a bridge that can operate efficiently with over 100 operators.

所提出的 Rollup 系統採用去中心化治理模型，「理論上對參與者數量沒有限制」。新運營商可以按照既定程序加入和退出網路。 Sovryn 是一個比特幣 DeFi 平台，旨在創建一座能夠與 100 多家營運商高效運作的橋樑。

Surpassing Sidechains and L2s

超越側鏈和 L2

Yago asserts that Sovryn's BitcoinOS rollups have the potential to render competing L2s and sidechains obsolete due to their superior security and direct connection to the Bitcoin network. He emphasizes, "Rollups offer both the robust security of Bitcoin and a decentralized Bitcoin peg, making them a significant improvement over sidechains."

Yago 斷言，Sovryn 的 BitcoinOS 匯總有可能使競爭性的 L2 和側鏈過時，因為它們具有卓越的安全性和與比特幣網路的直接連接。他強調，“Rollups 既提供了比特幣強大的安全性，又提供了去中心化的比特幣掛鉤，使它們比側鏈有了顯著的改進。”

Defeating State-Level Attacks

擊敗國家級攻擊

The proposed rollup system is designed with an unwavering focus on security, boasting the ability to withstand even the most sophisticated attacks.

擬議的匯總系統在設計時堅定不移地關注安全性，並擁有抵禦最複雜攻擊的能力。

"The system is meticulously engineered to thwart state-level adversaries," Yago proclaims. "A single ethical coder operating from their basement can effectively counter a coalition of nation-states."

亞戈宣稱：“該系統經過精心設計，旨在挫敗國家級對手。” “一個在地下室工作的道德編碼員可以有效地對抗民族國家聯盟。”

Conclusion
