近期,关于 wBTC 项目控制权转移的问题在社区内引起了广泛的讨论和担忧。社区所担心的点是什么?除了 wBTC 以外还有什么可以选择使用的封装型比特币?

 

首先让我们来回顾一下发生了什么事情?事情的起因是 8 月 6 日加密货币资产服务商 BitGo 宣布与全球托管平台 BiT Global 建立合资企业以加速 wBTC 业务的全球化战略扩张,以实现其 wBTC 业务转变为跨司法管辖区和跨机构托管的业务。

 

同时将 wBTC 项目的控制权在 60 天内从 BitGo 转交给孙宇晨以及 BiT Global 相关的机构。而这一举措让 wBTC 的利益相关方 MakerDAO 感到担忧,安全团队指出孙宇晨在控制 TUSD 之后,其运营流程和透明度出现了恶化,前管理团队离职,实施储备金证明中断,在赎回服务中造成 TUSD 多次严重脱钩,以及孙宇晨关联的 RWA 项目声称持有美国国债储备,但没有提供明确的审计或者证据。综合评价孙宇晨作为新的 wBTC 合资企业相关人员,对 MakerDAO 而言风险过高,因此 MakerDAO 决定限制 wBTC 的风险敞口。

 

MakerDAO 作为全网 TVL 排名第一的稳定币发行协议,其举措毫无疑问会引起市场的关注。关于后续 MakerDAO 是否继续使用 wBTC 作为稳定币 DAI 的抵押品, 其安全团队要求 BiT Global 披露公司的详细信息包括具体位置、公司编号、董事与员工、所有权结构、私秘钥管理信息、以及进行战略合资与孙宇晨是否参与公司运营等。虽然后续孙宇晨发推承诺不会动用 BitGo 的储备,但仍未正面回复 MakerDAO 提出的要求。

 

除了 wBTC 外,还有没有可以让用户参与到 DeFi 当中的封装型比特币呢?有,那就是 dlcBTC,与 wBTC 不同,dlcBTC 采取了比特币协议 Discreet log contracts 允许用于在自托管钱包实现自封装铸造,完全实现自托管而不用担心目前 wBTC 托管风险的问题。

与 wBTC 相比, dlcBTC 有以下优点:

 

  • 自我封装: dlcBTC 是由存款人 (dlcBTC 商家) 自我封装,将 BTC 锁定在 DLC 中。自我封装意味着 DLC 只能支付给原始存款人,这样 BTC 就不会在黑客攻击中被盗或被政府行动没收。

 

  • 完全自动: 由于 BitGo 托管过程中存在手动步骤,wBTC 的铸币或销毁需要花费 3-12 个小时。而 dlcBTC 则完全自动化,在 3-6 个 BTC 块确认中即可完成铸币或销毁。

 

  • 费用灵活: 由于 DLC.Link 不是托管方,dlcBTC 的开销更低,从而提供了更具竞争力的铸币和销毁费用。

 

 

在不会爆仓的链上期权协议 Jasper Vault 上,已支持 wBTC 与 dlcBTC 交易品种,产品分为面向散户的,旨在降低准入门槛的日内到期期权,以及面向专业投资者的美式期权,提供实物交割模式和差额利润交割模式两种交割模式来适配持续上涨行情和震荡行情。

 

Jasper Vault 协议上的 dlcBTC 目前交易的时间段从 2 小时到 24 小时,杠杆率最高可达 300 倍而没有爆仓的风险。

 

Jasper Vault 称,客户如果担心 wBTC 价格不稳定,可以在 Jasper Vault 协议上用看跌期权来做风险对冲,或者买入高杠杆看跌获利,也可以选择直接交易 dlcBTC 的看涨看跌期权。由于平台近期提供了大量免费的 NFT 来让用户尝试交易 dlcBTC,dlcBTC 的交易量显著增加。

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.
