上海升级后质押解锁,ETH将面临多大抛压?

Odaily星球日报Publicado a 2022-12-11Actualizado a 2022-12-11

Resumen

每天最大解锁5万枚ETH。

以太坊核心开发人员在本周四的 All Core Developers 会议上敲定了网络下一个硬分叉的一部分,这一升级被称为“上海”。

对普通投资者来说,上海升级除了进行一系列技术革新,更为受到瞩目的升级则在于质押解锁。自 ETH PoS 质押机制诞生以来,巨量的 ETH 被质押锁仓,这些 ETH 在未来解锁之后,又将如何冲击市场?

“上海”升级了什么?

本次升级定于 2023 年 3 月进行,将开放信标链质押的ETH提款,即 EIP 4895 。

开发人员还同意在上海升级解决 EVM 对象格式 (EOF) 的实施问题,本质上是升级以太坊虚拟机。这一改进又一系列 EIP 进行,包括 EIP 3540、EIP 3670、EIP 4200、EIP 4570、EIP 5450 。

开发人员还同意在 2023 年秋季的某个时候进行第二次硬分叉,这将解决另一个重要的扩展升级——proto-danksharding,也称为 EIP 4844 。EIP 4844 将通过分片使以太坊更具可扩展性,分片是一种将网络分成“shards”的方法,以此来增加其容量并降低 gas 费。

在周四的电话会议之后,以太坊开发人员的目标是在 12 月 15 日至 16 日左右为上海(升级)推出一个新的公共测试网。以太坊开发人员将在下个月集中精力使上海尽可能顺利,并计划在 2023 年 1 月中下旬启动主网影子分叉。

退出受限

目前,ETH 总质押量超过 1555 万枚,ETH 总供应量的 13% 已被质押。若以当前价格计算,这些面临释放的 ETH 总价值超 198 亿美元。

但所幸的是,这些 ETH 并不会被全部抛向市场——即便持有者有这种想法,他们也并不能做到。

早在 ETH 转 PoS 之初,设计者就考虑到了大量 ETH 取款对市场所造成的冲击。因此,对验证者节点取款退出做出了一些限制。

当验证节点发起退出请求之后,并不能立即退出,而是进入退出队列之中。根据退出机制的设计, ETH 提现存在一个名为“流失限制系数”(Churn Limit Quotient)的概念,该系数为验证者总数量 / 65536 。这一数字代表了以太坊链上每个 epoch 可退出的最大数量。

截至本文发布时,信标链上共有 485, 573 名以太坊验证者。即目前每个 epoch 可退出 485, 573 / 65, 536 ≈ 7 名验证者。

而所有验证者都将依序排队退出,以这一退出速度计算,每天可退出 1575 名验证者,每验证者质押 32 ETH,因此每天最多解锁 5.04 万枚 ETH。

即便是当前所有的质押 ETH 全部退出——而这是不可能的,这意味着以太坊网络已经不复存在——仍需 311 天才可完成全部质押 ETH 的提款。

ETH 质押在何处?

目前来看,质押服务提供商仍是最大的质押来源。Dune 数据显示,约三分之一的 ETH 质押来自质押服务商,而中心化交易所所占份额与其几乎相等,位列第二。此外,巨鲸独立质押的 ETH 数量也不容小觑,拥有超过五分之一的份额。

而 Lido 作为最为流行的质押服务商,拥有着 29% 的市场份额,质押了约 460 万枚 ETH,Coinbase 紧随其后,质押量超过 200 万枚。

此前,stETH 价格曾几度脱锚,与上海升级解锁所释放 ETH 抛压相比,或许 stETH 的脱锚更为值得担忧。目前,Curve 的 stETH/ETH 流动性池中 stETH 占比为 62% ,池中仅拥有 22 万枚 ETH。目前 stETH 仍存在约 1% 的负溢价。

质押风险,或更多来自监管

目前来看,质押解锁对 ETH 的抛压似乎并无人们所想象的一样巨大。

现如今加密市场已经稍趋于回暖,质押解锁的冲击或许并不值得过多关心。而更为值得关心的仍是老调重弹的监管问题。

Etherscan 的节点追踪统计显示,约一半的质押节点来自美国,监管风险或许仍是质押的最大风险。

早在今年 9 月,SEC 主席Gary Gensler 就曾表示,允许持有人“质押”其代币的加密货币和中介机构可能需要通过 Howey 测试来确定其资产是否为证券,这意味着PoS加密货币可能会受到联邦证券法规的约束。

PoS 共识的加密货币是否属于证券的问题长久以来一直悬而未决。待上海升级升级完成,ETH 解锁并产生收益,监管是否将继续发难,或会成为 PoS ETH 的达摩克利斯之剑。

GPT-5.6 Countdown: Abandon the Illusion of a Single API, Computational Iteration Can't Outpace a Single Page of Compliance

In mid-June, three seemingly independent industry events—the compliance-driven throttling of Fable 5, the open-sourcing of GLM-5.2, and the leaked release timeline for GPT-5.6—are pushing the global AI industry toward a watershed moment. These shifts signal a fundamental restructuring of the industry's underlying logic. First, **"usability" has substantially overtaken "advanced capabilities"** as the primary weight, pushing the global large language model (LLM) supply chain into a "dual-track" phase of controlled closed-source and local open-source coexistence. Second, **the competitive moats of closed-source giants are shifting**. Their technical focus is moving from "language intelligence" toward "spatial intelligence (world models)"—a domain heavily reliant on computing power. Third, faced with常态化 transnational compliance risks, **a "model-agnostic" decoupled design has become a survival necessity for application-layer developers to maintain business continuity.** The article details how Anthropic's Fable 5, despite its advanced engineering feats, was restricted for non-U.S. citizens within 72 hours of launch, highlighting how geopolitical compliance can instantly limit even the most advanced models. In response, the open-source camp, exemplified by Zhipu AI's MIT-licensed GLM-5.2, is gaining market share by offering stable performance improvements and significant cost advantages (up to 70% savings for enterprises), while achieving full adaptation with domestic semiconductor platforms. Meanwhile, closed-source leaders like OpenAI are pivoting. The anticipated GPT-5.6 reportedly shifts focus from language to spatial intelligence and world models, aiming to rebuild a generational gap in areas like 3D understanding, simulation, and industrial design that demand immense compute. The core conclusion is that the LLM supply chain's logic has changed. Enterprises must now evaluate infrastructure based on a composite of technical performance and policy compliance. For developers, complete reliance on a single closed-source API poses unacceptable risk. Implementing a truly model-agnostic architecture—enabling swift switches to compliant, locally deployable open-source alternatives—is no longer just good practice but a fundamental baseline for business continuity.

Is the 'Token Subsidy War' Among AI Giants Almost Over?

The article discusses the ongoing "token subsidy war" among AI giants like OpenAI and Anthropic, questioning whether it's nearing its end. It reveals that current AI subscription prices are heavily subsidized, with some plans offering tokens at up to 70 times the actual cost to attract and retain heavy users, especially developers and enterprises. This strategy mirrors past internet-era subsidy battles, but with a key difference: AI tokens lack "lock-in" effects. Unlike ride-hailing or food delivery apps, users can easily switch between AI providers as APIs become standardized, making it difficult for companies to raise prices post-subsidy. The piece highlights a structural asymmetry in the competition. Giants like Google, with massive advertising revenue, can afford to subsidize tokens indefinitely, akin to using "tokens as a weapon." In contrast, venture-backed companies like OpenAI and Anthropic face pressure to become profitable, especially as they approach IPO. The article cites Google Ventures founder Bill Maris, who suggests Google could slash token prices by 80%, putting immense pressure on competitors. Two potential endgames are presented: the "internet service" model (subsidize, monopolize, then raise prices) and the "utility" model (tokens become a standardized, low-margin commodity like electricity). Given the low switching costs, the latter seems more likely. The competition may not have a single winner but could instead accelerate AI's evolution into a foundational, infrastructure-level technology, akin to a public utility. For now, users continue to benefit from heavily subsidized token costs.

Beyond the Stadium: The Profitable Games Surrounding the World Cup

"Beyond the Pitch: The Profit Game Around the World Cup" The FIFA World Cup transcends being a sporting spectacle, evolving into a massive global arena for speculation and profit-seeking. The 2026 tournament has amplified this dynamic, creating a multi-layered ecosystem of financial opportunism alongside the football. **Prediction markets** have surged into the mainstream. Platforms like Polymarket and Kalshi saw trading volumes for World Cup contracts soar, attracting new users with their financial trading model and high-profile, chain-based wealth stories that overshadow traditional sports betting in terms of growth and narrative. However, **traditional sportsbooks** remain the dominant force, leveraging established user habits, legal markets, and comprehensive product offerings to handle the vast majority of speculative wagers, with projections suggesting record-breaking betting volumes. Capital markets also react. **"Concept stocks"** in countries like South Korea and Japan experience volatile price swings based on team performance and anticipated fan spending on items like chicken, beer, and viewing parties, effectively becoming a stock market reflecting fan sentiment. The **ticket resale market** has become a sophisticated arena for arbitrage. Prices fluctuate wildly based on team draws and star power, with sellers sometimes listing tickets they don't yet own in a practice akin to short-selling, while FIFA's own "Right to Buy" tokens add another layer of speculative trading. **Collectibles and merchandise** offer another avenue. Panini sticker albums, with their inherent scarcity and nostalgic value, can become high-value collectibles. Limited-edition or locally themed jerseys command significant premiums on secondary markets, and even counterfeit vendors profit from fans' desire for affordable match-day identity. The **cryptocurrency** space has seen a frenzy of speculative, unauthorized World Cup-themed meme coins on chains like Solana. These tokens, often exploiting team names and player imagery, experience extreme pump-and-dump cycles, creating stories of massive gains for a few early entrants and steep losses for many others. Finally, an entire industry thrives on **providing information and tools** to other speculators. Developers create platforms like SeatSidekick to track ticket inventory and prices, while paid Telegram groups and subscriptions sell betting tips and predictions, monetizing the widespread desire for an informational edge. In essence, the World Cup has become a compressed, global laboratory for speculation. While the games determine champions on the field, a parallel, complex network of financial transactions—spanning prediction contracts, bets, stocks, tickets, collectibles, crypto, and information services—settles its own scores in the global market.

How Does Codex Use a Computer? Three Entry Points and Permission Boundaries

This article explains the three primary methods for Codex to interact with a computer, each with distinct use cases, permission boundaries, and trust levels. **1. Computer Use:** This offers the broadest access, allowing Codex to visually control and interact with the graphical user interface of authorized macOS/Windows apps, system settings, and even iOS simulators. It's ideal for tasks lacking APIs or structured tools, such as operating legacy software or multi-app workflows. However, it's the slowest method and has the widest permission scope, requiring careful supervision for sensitive actions. **2. Chrome Extension:** This grants Codex access to the user's logged-in Chrome browser state, including cookies, profiles, and open tabs. It's best for tasks requiring user identity across websites like Gmail, LinkedIn, Salesforce, or internal dashboards. Its key advantage is multi-tab control for complex workflows. While more powerful for browser-based tasks than Computer Use, it carries higher sensitivity as actions are performed under the user's identity. **3. In-App Browser:** This is a browser isolated within the Codex thread, separate from the user's personal browsing data. It excels in web development and debugging scenarios—previewing local servers, testing responsive layouts, or annotating designs directly on the page. Its isolation is a strength for development but a limitation for tasks requiring login sessions. The core principle is to choose the narrowest, safest, and most structured interface for the task. Use plugins or MCPs first, resort to visual control (Computer Use) only for GUI-dependent tasks, employ the Chrome extension for identity-reliant browser work, and prefer the In-App Browser for isolated development. **Appshots** are clarified as a fourth, complementary tool for *inputting* context—capturing a screenshot of a window to point Codex to something—rather than a method for Codex to *act*. Together, this layered approach highlights a key to AI agent productization: not granting unlimited permissions, but constraining them within clear boundaries for specific tasks while preserving user oversight.
