比特币汇总：革命性的范式转变释放了可扩展性和图灵完备性

一个加密货币开发团队提出了一个新框架，可以在比特币区块链上实现交易汇总，此举可能会将智能合约、DeFi 和其他应用程序引入世界上最古老的加密货币中。该框架名为 BitSNARK，使用 ZK 证明和质询响应序列来验证交易，类似于乐观汇总。

Bitcoin Rollups: A Revolutionary Paradigm Shift

比特币汇总：革命性的范式转变

Introduction

介绍

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.

随着在比特币上引入交易汇总的突破性计划的出现，加密货币世界见证了显着的突破。这一革命性的概念曾经被认为在受人尊敬的区块链上是不可能实现的，但它有可能引发变革性的创新浪潮，并将比特币的功能扩展到其当前的边界之外。

The Promise of Rollups: Scaling and Enhanced Functionality

Rollups 的前景：扩展和增强功能

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 是一种去中心化机制，用于在链外捆绑加密交易，然后以更高效的方式在链上进行结算，历史上一直被用作以太坊的扩展解决方案。然而，拟议的比特币汇总框架（称为 BitSNARK 和 Grail）的创建者预计该技术将发挥更全面的作用。他们断言，汇总不仅会增强比特币的容量，还会引入完整的图灵完备功能。

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.

图灵完备性是计算机科学的一个基本概念，意味着比特币将获得执行智能合约的能力。这为部署去中心化金融（DeFi）应用程序以及目前比特币上不可用的各种其他功能提供了可能性。

BitSNARK and Grail: Laying the Foundation for Bitcoin Rollups

BitSNARK 和 Grail：为比特币 Rollup 奠定基础

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.

拟议的比特币汇总框架由两项关键创新组成：BitSNARK 和 Grail。 BitSNARK 是一个专门用于验证比特币上的 zkSNARK 的软件库。 zkSNARK（零知识简洁非交互式知识论证）是加密证明，可以验证已完成的交易，而无需透露任何其他细节。

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 的基础上，是创建比特币汇总桥的实用且可扩展的实现。 Grail 桥将使用户能够在近乎无信任的环境中在第 2 层网络和比特币区块链之间无缝转移 BTC 和其他资产。

Combining Elements of ZK and Optimistic Rollups

结合 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，比特币 Rollup 具有独特的特征，使其与以太坊上的 ZK 和 Optimistic Rollup 区分开来。

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

“比特币汇总利用 ZK 证明进行验证，但它们采用了在某些方面类似于乐观汇总的挑战-响应序列，”Yago 解释道。

Intermediary Operators: Ensuring Security and Integrity

中介运营商：确保安全和诚信

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.

虽然BitcoinOS系统消除了对Bitcoin Core进行软或硬分叉升级的需要，但它依赖于被称为“运营商”的中介机构来促进桥梁存款和取款。这些运营商持续监控彼此的活动，防止恶意行为者窃取用户资金或执行欺诈交易。

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

Yago 强调了系统的弹性，并表示：“只要单个操作员保持诚实，系统的完整性就可以保持。”

Decentralized Governance and Scalability

去中心化治理和可扩展性

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.

拟议的 Rollup 系统采用去中心化治理模型，“理论上对参与者数量没有限制”。新运营商可以按照既定程序加入和退出网络。 Sovryn 是一个比特币 DeFi 平台，旨在创建一座能够与 100 多家运营商高效运营的桥梁。

Surpassing Sidechains and L2s

超越侧链和 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 断言，Sovryn 的 BitcoinOS 汇总有可能使竞争性的 L2 和侧链过时，因为它们具有卓越的安全性和与比特币网络的直接连接。他强调，“Rollups 既提供了比特币强大的安全性，又提供了去中心化的比特币挂钩，使它们比侧链有了显着的改进。”

Defeating State-Level Attacks

击败国家级攻击

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

拟议的汇总系统在设计时坚定不移地关注安全性，拥有抵御最复杂攻击的能力。

"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."

亚戈宣称：“该系统经过精心设计，旨在挫败国家级对手。” “一个在地下室工作的道德编码员可以有效地对抗民族国家联盟。”

Conclusion

结论

The introduction of rollups on Bitcoin marks a watershed moment in the evolution of cryptocurrency. This groundbreaking technology has the potential to unlock a new era of scalability, innovation, and enhanced functionalities for the venerable blockchain. The proposed Bitcoin rollup framework, with its novel components BitSNARK and Grail, promises to transform Bitcoin into a platform capable of supporting a vast ecosystem of decentralized applications and financial services.
