BitVM2：最新的比特币扩容解决方案承诺“重大改进”

比特币扩容解决方案比特币虚拟机（BitVM）的创建者已经推出了其侧链的第二次迭代，称为“BitVM2”和 BitVM Bridge，他们表示现在为原始系统提供了“重大改进”。

The creators of Bitcoin scaling solution Bitcoin Virtual Machine (BitVM) have unveiled the second iteration of their sidechain and the BitVM Bridge, touting “major improvements” to the original system.In an Aug. 15 post to X, BitVM co-founder Alexei Zamyatin shared an overview of a new whitepaper that introduces a fresh framework for how BitVM2 and the BitVM Bridge would function.ZeroSync project lead and BitVM creator Robin Linus first unveiled BitVM in October last year in a bid to bring off-chain smart contracts to the Bitcoin network without requiring a soft fork.One of the main improvements of the latest version is that it will now be “permissionless,” meaning anyone can challenge suspicious transactions, with only three transactions now required to complete a challenge.The previous version of BitVM required up to 70 transactions to complete a challenge, and only a small number of specific parties could make challenge requests.BitVM2 is also designed to be more efficient in terms of capital utilization and lock-up periods for users transferring their Bitcoin to the rollup and withdrawing it.Overall, BitVM2's main focus is to enable a rollup — a separate network built on Bitcoin — capable of processing transactions more efficiently but with similar security to the original Bitcoin network.The BitVM Bridge would allow users to safely transfer their Bitcoin to the rollup and withdraw it, with shorter lock-up periods and smaller upfront capital requirements.The paper was led by ZeroSync project lead Robin Linus and other co-authors, including Zamyatin, Lukas Aumayr, Andrea Pelosi, Zeta Avirikioti, and Matteo Maffei.BitVM was unveiled in an Oct. 9 whitepaper titled “BitVM: Compute Anything on Bitcoin” — enabling Turing-complete Bitcoin contracts without altering any of Bitcoin’s consensus rules.Related: Bitcoin needs De Fi, consumer apps for mass adoption — L2 devsThe paper’s release inspired a wave of development on the Bitcoin network, with a swathe of Bitcoin-based layer-2 networks and rollups popping up in its wake.Developers of the BitVM project have reiterated that BitVM is intended to scale the Bitcoin network rather than launch Ethereum-like decentralized finance (DeFi) applications on Bitcoin.Pseudonymous BitVM developer Super Testnet told Cointelegraph in October 2023 that the overarching goal of BitVM was to increase Bitcoin’s scalability above all else.He said he didn’t want BitVM to be flooded with EVM-like tokens because it would potentially attract bad actors to Bitcoin and said building a decentralized exchange on Bitcoin would be a “step backward.”Magazine: AI may already use more power than Bitcoin — and it threatens Bitcoin mining

比特币扩容解决方案比特币虚拟机 (BitVM) 的创建者推出了其侧链和 BitVM Bridge 的第二次迭代，宣传对原始系统的“重大改进”。 在 8 月 15 日发布的 X 帖子中，BitVM 联合创始人 Alexei Zamyatin分享了一份新白皮书的概述，该白皮书介绍了 BitVM2 和 BitVM Bridge 如何运作的新框架。ZeroSync 项目负责人兼 BitVM 创建者 Robin Linus 于去年 10 月首次推出了 BitVM，旨在将链下智能合约引入比特币网络无需软分叉。最新版本的主要改进之一是它现在是“无需许可的”，这意味着任何人都可以挑战可疑交易，现在只需要三笔交易即可完成挑战。BitVM 的先前版本需要最多 70 笔交易即可完成挑战，并且只有少数特定方可以提出挑战请求。BitVM2 在资金利用和用户将比特币转入汇总和提现的锁定期方面也被设计得更加高效总体而言，BitVM2 的主要重点是实现 Rollup（一个基于比特币构建的独立网络），能够更有效地处理交易，但具有与原始比特币网络类似的安全性。BitVM Bridge 将允许用户安全地将其比特币转移到 Rollup并撤回它，锁定期更短，前期资本要求更小。该论文由 ZeroSync 项目负责人 Robin Linus 和其他合著者领导，包括 Zamyatin、Lukas Aumayr、Andrea Pelosi、Zeta Avirikioti 和 Matteo Maffei。BitVM 是在 10 月 9 日题为“BitVM：在比特币上计算任何东西”的白皮书中公布——在不改变任何比特币共识规则的情况下实现图灵完备的比特币合约。相关：比特币需要 Defi、消费者应用程序才能大规模采用——L2 开发者该论文的发布激发了比特币网络的发展浪潮，随之而来的是一系列基于比特币的二层网络和汇总网络。BitVM 项目的开发人员重申，BitVM 的目的是扩展比特币网络，而不是推出类似以太坊的去中心化网络。比特币上的金融（DeFi）应用。假名 BitVM 开发者 Super Testnet 于 2023 年 10 月告诉 Cointelegraph，BitVM 的首要目标是提高比特币的可扩展性。他表示，他不希望 BitVM 被类似 EVM 的代币淹没，因为它可能会吸引不良行为者使用比特币，并表示在比特币上建立去中心化交易所将是“倒退”。 杂志：人工智能可能已经比比特币使用更多的电力 - 并且它威胁到比特币挖矿
