摘要

  • Robin Linus 和合著者团队撰写的新“BitVM2”论文标志着从初始设计向前迈进了一步。

  • 该项目将依靠先进的加密技术和新颖的设计来促进将比特币从主网络转移到辅助网络(称为“Rollup”)的安全“桥梁”。

  • 与早期版本不同,BitVM2 是“无需许可的”,允许任何人质疑可疑交易,而不仅仅是一组固定的操作员。

比特币开发者罗宾·林纳斯 (Robin Linus) 去年以理论方法让最古老、最原始的区块链更具可编程性,震惊了加密技术领域。他推出了第二个版本“BitVM2”,宣称其有了重大改进,可能让这一概念更接近实际实施。

根据林纳斯和五位合著者周四发布的白皮书,基本设置包括使用加密技术将程序压缩为子程序,然后可以在比特币交易中执行。

然后,在三个链上交易中对程序进行“验证”,基本上确保没有人试图作弊或盗窃。据联合创始人之一阿列克谢·扎米亚京 (Alexei Zamyatin) 称,在之前的版本中,验证可能需要 70 笔交易,扎米亚京还为一个名为 BOB(Build on Bitcoin 的缩写)的项目工作。

新版本的一个关键改进是,任何人都可以质疑可疑交易,这一功能被称为“无需许可的挑战”。在去年 10 月发布但从未真正投入实际实施的原始 BitVM 中,只有一组固定的操作员可以发起挑战。

“这种设计为我们带来了重大改进,”Zamyatin 在接受采访时表示。“我们现在对 BitVM 范式有了全面的描述。”

Linus 是 ZeroSync Association 的核心贡献者,该协会是一家位于瑞士祖格州的非营利组织。除了 Zamyatin 之外,其他合著者还包括 Lukas Aumayr、Andrea Pelosi、Zeta Avarikioti 和 Matteo Maffei。

Linus 的项目被誉为一项突破,部分原因是它不需要对底层比特币代码进行任何更改。这一点至关重要,因为与大多数后续区块链项目相比,比特币在治理上更加完全去中心化;比特币并没有像以太坊或 Solana 那样真正有一个指导基金会、管理机构或首席开发人员。

即使是像备受讨论的 OP_CAT 这样看似温和的提案,也难以被比特币代码的维护者采纳,因为几乎完全的共识已经发展成为建议更新的事实标准。

BitVM2 的初始应用是启用“rollup”——本质上是比特币之上的独立辅助网络,可以处理更快、更便宜的交易,但具有类似的安全保障。

Linus 的原始设计的发布就激发了在比特币上构建项目的热情;截至 7 月,CoinDesk 统计至少有 83 个比特币第 2 层项目正在筹备中,具有各种设置,包括 rollup 和侧链。

新范式可用于创建区块链“桥”,可用于安全地将比特币转移到 rollup,然后安全地将其带回,以便可以提取存款。

虽然比特币的工作量证明共识机制(确认交易的方法,本质上涉及数据中心不间断地解决加密难题,耗电量很大)因其对环境的影响而受到批评,但大多数区块链专家都认为它是最安全的区块链。

这种优点得到了所有未偿还比特币 1.2 万亿美元市值的强调——超过所有其他加密货币的总和。

Linus 在 Telegram 消息中指出:“我们新的桥梁设计更简单,资本效率更高。”“以前的设计造成了流动性问题,无论是桥梁运营商需要锁定多少抵押品,还是锁定多长时间。现在,它需要的资本更少,锁定时间更短。”

DIGITAL GOLD ($BITCOIN): A Comprehensive Analysis Introduction to DIGITAL GOLD ($BITCOIN) DIGITAL GOLD ($BITCOIN) is a blockchain-based project operating on the Solana network, which aims to combine the characteristics of traditional precious metals with the innovation of decentralized technologies. While it shares a name with Bitcoin, often referred to as “digital gold” due to its perception as a store of value, DIGITAL GOLD is a separate token designed to create a unique ecosystem within the Web3 landscape. Its goal is to position itself as a viable alternative digital asset, although specifics regarding its applications and functionalities are still developing. What is DIGITAL GOLD ($BITCOIN)? DIGITAL GOLD ($BITCOIN) is a cryptocurrency token explicitly designed for use on the Solana blockchain. In contrast to Bitcoin, which provides a widely recognized value storage role, this token appears to focus on broader applications and characteristics. Notable aspects include: Blockchain Infrastructure: The token is built on the Solana blockchain, known for its capacity to handle high-speed and low-cost transactions. Supply Dynamics: DIGITAL GOLD has a maximum supply capped at 100 quadrillion tokens (100P $BITCOIN), although details regarding its circulating supply are currently undisclosed. Utility: While precise functionalities are not explicitly outlined, there are indications that the token could be utilized for various applications, potentially involving decentralized applications (dApps) or asset tokenization strategies. Who is the Creator of DIGITAL GOLD ($BITCOIN)? At present, the identity of the creators and development team behind DIGITAL GOLD ($BITCOIN) remains unknown. This situation is typical among many innovative projects within the blockchain space, particularly those aligning with decentralized finance and meme coin phenomena. While such anonymity may foster a community-driven culture, it intensifies concerns about governance and accountability. Who are the Investors of DIGITAL GOLD ($BITCOIN)? The available information indicates that DIGITAL GOLD ($BITCOIN) does not have any known institutional backers or prominent venture capital investments. The project seems to operate on a peer-to-peer model focused on community support and adoption rather than traditional funding routes. Its activity and liquidity are primarily situated on decentralized exchanges (DEXs), such as PumpSwap, rather than established centralized trading platforms, further highlighting its grassroots approach. How DIGITAL GOLD ($BITCOIN) Works The operational mechanics of DIGITAL GOLD ($BITCOIN) can be elaborated on based on its blockchain design and network attributes: Consensus Mechanism: By leveraging Solana’s unique proof-of-history (PoH) combined with a proof-of-stake (PoS) model, the project ensures efficient transaction validation contributing to the network's high performance. Tokenomics: While specific deflationary mechanisms have not been extensively detailed, the vast maximum token supply implies that it may cater to microtransactions or niche use cases that are still to be defined. Interoperability: There exists the potential for integration with Solana’s broader ecosystem, including various decentralized finance (DeFi) platforms. However, the details regarding specific integrations remain unspecified. Timeline of Key Events Here is a timeline that highlights significant milestones concerning DIGITAL GOLD ($BITCOIN): 2023: The initial deployment of the token occurs on the Solana blockchain, marked by its contract address. 2024: DIGITAL GOLD gains visibility as it becomes available for trading on decentralized exchanges like PumpSwap, allowing users to trade it against SOL. 2025: The project witnesses sporadic trading activity and potential interest in community-led engagements, although no noteworthy partnerships or technical advancements have been documented as of yet. Critical Analysis Strengths Scalability: The underlying Solana infrastructure supports high transaction volumes, which could enhance the utility of $BITCOIN in various transaction scenarios. Accessibility: The potential low trading price per token could attract retail investors, facilitating wider participation due to fractional ownership opportunities. Risks Lack of Transparency: The absence of publicly known backers, developers, or an audit process may yield skepticism regarding the project's sustainability and trustworthiness. Market Volatility: The trading activity is heavily reliant on speculative behavior, which can result in significant price volatility and uncertainty for investors. Conclusion DIGITAL GOLD ($BITCOIN) emerges as an intriguing yet ambiguous project within the rapidly evolving Solana ecosystem. While it attempts to leverage the “digital gold” narrative, its departure from Bitcoin's established role as a store of value underscores the need for a clearer differentiation of its intended utility and governance structure. Future acceptance and adoption will likely depend on addressing the current opacity and defining its operational and economic strategies more explicitly. Note: This report encompasses synthesised information available as of October 2023, and developments may have transpired beyond the research period.
