BitVM2：最新的比特幣擴容解決方案承諾“重大改進”

比特幣擴容解決方案比特幣虛擬機器（BitVM）的創建者已經推出了其側鏈的第二次迭代，稱為「BitVM2」和 BitVM Bridge，他們表示現在為原始系統提供了「重大改進」。

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

比特幣擴容解決方案比特幣虛擬機器(BitVM) 的創建者推出了其側鍊和BitVM Bridge 的第二次迭代，宣傳對原始系統的「重大改進」。 BitVM 聯合創始人Alexei Zamyatin分享了一份新白皮書的概述，該白皮書介紹了BitVM2 和BitVM Bridge 如何運作的新框架。將鏈下智能合約引入比特幣網路無需軟分叉。完成挑戰。高效總體而言，BitVM2 的主要重點是實現Rollup（一個基於比特幣構建的獨立網路），能夠更有效地處理交易，但具有與原始比特幣網路類似的安全性。其比特幣轉移到Rollup並撤回它，鎖定期更短，前期資本要求更小。 。幣需要Defi、消費者應用程式才能大規模採用——L2 開發者該論文的發布激發了比特幣網路的發展浪潮，隨之而來的是一系列基於比特幣的二層網路和匯總網路。專案的開發人員重申，BitVM 的目的是擴展比特幣網絡，而不是推出類似以太坊的去中心化網絡。 ，BitVM 的首要目標是提高比特幣的可擴展性。化交易所將是「倒退」。
