Abstract

模块化L1 Particle Network提供了实现链抽象的SDK平台。

作为 Crypto/Web3 生态系统的关键入口,钱包一直是创业团队竞争的焦点。除了以支持新公链为首的钱包产品外,还有很多团队希望能彻底改善 MetaMask 的体验(比如 Rabby)。当钱包团队还在关注账户抽象时,更高维度的链抽象(Chain Abstraction)叙事逐渐引起社区的关注。

NEAR 联合创始人 Illia Polosukhin 前不久撰文探讨链抽象的概念,并表明 NEAR 在实现链抽象方面的愿景。此外上个月上线主网的 ZetaChain、模块化 L1 Particle Network、全链账本 Cycle Network 等项目都在为实现链抽象而探索。

链抽象为什么重要?

思考一个问题,为什么 Web3 的产品用户体验感和用户数量远低于 Web2?其中一个重要原因是现在很多项目的用户需要了解各种原理和概念,而 Web3 发展速度之快大家也有目共睹,新叙事新概念层出不穷,即使 Web3 老玩家也会有「热点变化太快学习起来太麻烦」的感觉。

举个简单的例子,跨链桥协议首先需要用户理解之间资产不能互通,所以需要这样子的桥接协议来实现资产在不同链之间的转移,其次得明白如果想将资产从以太坊转移到 Solana,需要需要支付 ETH 作为 Gas 费,而不是 SOL。我只是想用以太坊上的 100 USDT 去买 Solana 生态里的 NFT 怎么这么麻烦?

相比之下,Web2 的产品几乎都是包装好的,用户无需知道原理,也不知道背后谁和谁的合作关系。按照 Web2 产品体验的逻辑,我想买 Solana 生态里的 NFT,只要在这个 NFT 项目界面登入我的钱包,拿钱包里 100 USDT 直接买,最后我只要知道钱包里还剩多少钱,NFT 到账没就可以了。

链抽象将不同区块链之间的差异和复杂性抽象为一种统一的接口,使得用户和开发者可以在不同的链上无缝地进行交互和操作,最终目标就是让用户感知不到链的存在,同时又享受区块链去中心化带来的好处,与意图相结合,用户体验会更加丝滑。想象一下,用户只需拥有足够的资产,不管什么代币不管在什么链上,想怎么交易都行,并且可以设置交易的时间点、条件,同时还能确保交易是安全的、隐私的、完全由自己掌控的。

链抽象:多链时代下的三棱镜

链抽象的逐步实现

在当下多链环境中,不仅用户体验变得复杂,而且流动性分散,这些都阻碍了区块链技术的大规模采用。整合流动性的有效方式是建立一个独立的平台,提供可交互操作的统一接口,即实现链抽象的平台。

Particle Network 就是这样一个提供实现链抽象 SDK 的 L1,它通过抽象出账户、Gas 和流动性,打造了一个 dapp 背后用户无感知的开放网络接入层:

  • Universal Accounts(通用账户): 用户可以在不同的链上使用相同的账户进行交易和操作。母合约控制着 50 多条链上的 AA 账户,将账户地址打通,使得打包交易更快,跨链更快(5 s 内)。此外这也意味着释放更多的应用场景,比如 omnichain 的稳定币。

  • Universal Gas Token(通用 Gas 代币): 引入了通用 Gas 代币(SPARTI),用户可以使用该代币在不同的链上支付交易费用。不必持有每个链上的特定 Gas 代币,降低了跨链交易的成本和复杂性。并且 Particle Network 整合了 EigenLayer,通过将 SPARTI 代币和以太坊实现双重质押,从而增强网络的安全性。

  • Universal Liquidity(通用流动性): 通过实现流动性抽象,将不同链上的流动性聚合起来。比如用 USDT 在比特币生态里一建购买 BTC。Particle Network 充当流动性聚合协议,支持跨链原子交易执行。

Particle Network 的底层架构采用了 Cosmos SDK,并通过 CometBFT 共识引擎确保网络的安全性。这种模块化的底层架构使得 Particle Network 可以灵活地扩展和定制,满足不同应用场景的需求。此外, Particle Network 采用聚合式 DA,DA 不依赖于某一方(比如 Celestia 或者 EigenDA),通过在多个地方存储数据的副本来增强数据可用性。

链抽象为应用爆发做好准备

多链的时代也意味着多层套娃(rollup)的时代,在这样的背景下,链抽象就像三棱镜将多束光聚合成一束一样,将多个链统一起来,解决准入门槛高、教育用户困难等问题,避免了用户需要处理多个账户、网络切换、手续费等影响体验的操作。随着越来越多的项目和技术团队加入到链抽象的构建中,我们期待链抽象成为推动 Web3 生态系统向前发展的关键驱动力,为 Web3 带来更加统一、便捷和安全的用户体验,促进主流采用的进程。

Rented Faith: How Much of the Bitcoin ETF Inflows Is Real Money?

"Rented Conviction: How Much of Bitcoin ETF Flows Is Real Money" The weekly inflows into Bitcoin ETFs are often interpreted as a gauge of institutional belief. However, a significant portion of this activity is driven by a hidden arbitrage trade, not directional conviction. The core mechanism is a cash-and-carry arbitrage: traders buy spot Bitcoin (often via ETFs) while simultaneously shorting CME futures to lock in the price difference, or "basis." This delta-neutral trade is essentially an interest rate play. In weekly data, about half the fluctuation in ETF flows can be explained by new short positions added by leveraged funds (hedge funds), with a correlation of 0.70. Bitcoin's price movement in a given week shows no statistical power in predicting these flows. While this arbitrage trade drives weekly *volatility*, it is not the main component of the cumulative *stock*. Of the total ~$55 billion in net ETF inflows, the current net arbitrage position is only about $1 billion. The remainder is steady, directional buying averaging ~$400 million per week, which constitutes the vast majority of the accumulated "mountain" over two years. Thus, ETF flow data overstates the *volatility* of conviction, not its *level*. This arbitrage trade has been unwinding for nearly two years. Leveraged fund short positions peaked at ~$14 billion in late 2024 and have since declined to ~$4.5 billion. When the basis compresses to unprofitable levels, ETF inflows and short positions retreat together. Recent outflows should not be mistaken for a loss of faith but rather the routine unwinding of this rate trade. For Ethereum ETFs, the pattern is weaker. Accounting for staking yield makes the basis often negative, so neither strong conviction buying nor robust arbitrage supports its flows. To interpret ETF flows correctly, monitor the CME basis versus T-bill rates and leveraged fund net shorts. They reveal how much of the next "demand" headline is real. The real, patient buy-and-hold demand is what constitutes the enduring bulk of ETF assets.

Soaring Over Tenfold Within the Year: The Frenzy Over SK Hynix Leveraged Products

South China Morning Post The leveraged ETF tracking SK Hynix has surged over tenfold year-to-date, fueled by intense market speculation on the memory chip sector. By June 22, the value of the 'South Korea 2x Long SK Hynix ETF' listed in Hong Kong had skyrocketed by more than 1,061% since the start of the year, while its asset size exploded over twenty times from the end of last year. The rally is driven by AI-driven demand for high-bandwidth memory (HBM), with SK Hynix recently sampling its next-generation HBM4E product. However, industry professionals warn of significant risks. Leveraged ETFs magnify both gains and losses. During a recent market correction, while the underlying SK Hynix stock fell 19.1%, its double-leveraged ETF dropped nearly 38%. Korean regulators noted that such products could theoretically lose 60% in a single day. Additionally, these ETFs face risks like time decay in volatile markets, liquidity spirals during mass redemptions, and extreme price dislocations from market-making failures, as seen in early June when an ETF moved opposite to its underlying stock. The trading is predominantly driven by retail investors, with institutional capital largely absent due to the products' high volatility. Analysts caution that with the semiconductor sector at elevated valuations and facing geopolitical and supply chain uncertainties, leveraged ETFs pose a substantial threat of amplified losses for uninformed investors.

18 Months, Over 50x Surge: KIOXIA's Epic Comeback

KIOXIA, a NAND flash memory giant, staged a dramatic comeback driven by AI demand. After a period of significant losses, a failed merger, and missed HBM opportunities, its 2024 IPO began modestly. However, fueled by explosive demand for AI data storage, its stock price skyrocketed over 50 times within 18 months, making it Japan's most valuable company, surpassing Toyota. Its Q1 FY2026 profit guidance soared 30-fold year-over-year, with 2026 NAND capacity already sold out. Key to its success is its 3D NAND technology, BiCS FLASH. As the inventor of NAND, KIOXIA advanced its technology through generations, reaching over 200 layers by 2023. Key innovations include CBA (CMOS directly Bonded to Array), which separately manufactures control circuits and memory arrays for better performance, and OPS (On Pitch Select Gate) to increase density. The company is now developing high-capacity packages like an 8TB solution stacking 32 dies. Looking beyond NAND, KIOXIA is exploring 3D DRAM with its OCTRAM technology, using oxide semiconductor transistors for ultra-low leakage to reduce power consumption. This fundamental research differs from HBM and represents a long-term bet to extend its 3D expertise from NAND into future DRAM architectures. KIOXIA's story highlights how technological assets and shifting market cycles can rapidly transform a company's fortunes. While questions remain about sustaining growth beyond the current AI boom, its resurgence demonstrates that in semiconductors, being down does not necessarily mean being out.

Market Trends in U.S. Stocks (June 23): Peak at Listing? SpaceX Loses Over $800 Billion in Three Days, Tech Stocks Experience Severe Internal Divergence

Stock Market Trends (June 23): Did SpaceX Peak at IPO? The company loses over $800 billion in market value in three days as a sharp divergence unfolds within the tech sector. SpaceX's post-IPO decline of over 20%, falling below its first-day close, reflects a swift market repricing. The catalyst is a clear shift in narrative from "AI platform potential" to concerns over rising capital costs, as its $8.57 billion IPO and subsequent $20 billion debt offering are earmarked for acquisitions and refinancing existing bridge loans rather than de-leveraging. While high-valuation tech stocks like Google, Meta, Amazon, and Microsoft faced pressure, Micron surged nearly 7% to a record high following a strategic supply deal with Anthropic for HBM and memory, highlighting robust, tangible demand in AI infrastructure. The broader market saw funds rotate into more defensive industrial and financial names. Macro factors included a dip in oil prices to a three-month low on news of a US-Iran framework deal, though logistical hurdles for resuming full Strait of Hormuz shipments remain. Key events ahead include Nvidia's shareholder meeting, Micron's earnings, and the May PCE inflation data. The latter will be crucial in determining whether the sell-off in high-valuation growth stocks, which appears to have just begun, will persist.
