1. 为什么有些很好的币会被下架交易所?ANT是DAO的龙头,我不敢买山寨币了,怕Magic被交易所下架。

我现在都不是太在意交易所有没有上币。

早年的时候,信息严重不对称,普通散户想要了解一个币恐怕很主要的信息来源就是交易所。在那个年代,可能交易所上币对一个币的价格有着很强的助推作用。

可现在,我觉得这种信息不对称已经削弱了不少,越来越多散户是通过社交媒体了解的一手信息。

这个信息来源远强于交易所。

而且已经有不少案例说明等交易所再上一个币时,那个币已经在前期经历了相当一波猛烈的涨幅。

所以现在交易所上币对一个币的价格有影响,但远没有曾经的那么大了。

另外,现在交易所选币的水平在我看来也远不如以前了。它们现在似乎更在意的是一个币能不能带来短期的流量,而不是一个币有没有长线发展的潜力。

如果我们用更长远的眼光看一个币,它长期的走势如何最根本的还是要看它的基本面和团队建设。这样它的基本面好,团队持续发力建设,没上所的都会被上所。如果基本面不行、团队建设也不给力,上了所最后也会被抛弃。

具体说到ANT,这个币很早的时候我也买过,但后来全抛了。主要原因是DAO在最近这些年一直没有起色,而且在可见的未来似乎也看不到方向。所以这个赛道可能现在谈还太早了。

至于Magic,我还拿着,至少目前看不到很严重的问题。

2. ARB上的USDT和USDC常拿有没有问题?

我假设这里问的“有没有问题”是指技术上“是否安全”。

如果从这个角度理解,我认为它们和以太坊上发行的USDT及USDC比,那肯定是不如以太坊上的安全。

这是由链的安全性所决定的。

ARB是以太坊的第二层扩展。理论上ARB上所有的交易最终都要在以太坊上进行验证才能获得最终的确认。所以如果一笔USDT或者USDC的转账没有在以太坊上进行最终的确认,那这笔转账理论上还存在回滚/取消的可能。

此外,ARB目前的运作坦率地说还是非常的中心化的,它的安全性实际上完全依赖以太坊,自身几乎没有特别强的安全保障。

也就是说团队一旦出现大问题(或者排序器出现大问题),整条链都会完蛋。那时,不要说上面发行的USDT和USDC,上面发行的所有资产都完蛋了。

这不仅是ARB的问题,也是目前几乎所有以太坊二层扩展的问题。

正因为如此,所以业界对以太坊第二层扩展进行去中心化的呼声从来都是前仆后继,一浪高于一浪。

在这些二层扩展中,目前看,只有Metis在大步向着去中心化的方向前进。

不过话又说回来,ARB已经使用了这么久了,似乎谁也没有在这些安全细节上对它较真。而且USDT和USDC好像也开始频繁、广泛地在各类以太坊的第二层扩展上发行原生代币(非以太坊跨链而来)了,所以似乎大家都不在意ARB以及一众知名的第二层扩展在安全上潜藏的风险。

不管他人在不在意,我始终觉得还是要留个心眼。在使用中尽量使用以太坊上发行的稳定币。对二层扩展上的代币,如果安全性要求不那么高,平时也不用太纠结。

Ethereum Q1 2026 Report: Fees Decline, Users and Transaction Volume Hit New Highs

Ethereum Q1 2026 Report: Fees Down, Users & Transactions Hit New Highs Token Terminal's Q1 2026 report on Ethereum presents a pivotal development: the network achieved record highs in monthly active users (13.2M, +85.9% YoY), total transactions (200.4M, +81.5% YoY), and throughput (25.78 TPS), while transaction fees on the mainnet plummeted by 47.9% quarter-over-quarter. This shift is attributed to the network's strategic move into a "low fees for scale" phase, exemplified by the Fusaka upgrade which increased data capacity and lowered block space costs, releasing pent-up demand (a manifestation of Jevons's Paradox). The report highlights a core narrative shift for Ethereum: from a DeFi-centric blockchain to a global financial settlement layer. It maintains a dominant position in tokenized assets, holding majority market shares among top chains in stablecoins (61.8%), tokenized funds (73.0%), and tokenized commodities (84.0%). Growth in tokenized funds (+73.1% YoY) and commodities (+325.9% YoY) was particularly strong, driven by institutions like BlackRock and JPMorgan entering the space. Contrasting these usage gains, several USD-denominated value metrics declined in Q1: fully diluted market cap fell 30.3% QoQ, total value locked (TVL) dropped 11.0%, and ecosystem transaction volume decreased 24.0%. The report interprets this as Ethereum prioritizing long-term network expansion and cementing its role as the default settlement layer for finance over short-term fee capture. The commentary from Etherealize argues that, much like the early internet, Ethereum's open, permissionless model is poised to win over closed alternatives as institutional tokenization accelerates.

He Just Raised 2.7 Billion, and Li Fei-Fei Also Invested

Pete Florence, a former senior research scientist at Google DeepMind and a key contributor to the Vision-Language-Action (VLA) model architecture, is deliberately distancing his startup, Generalist AI, from the trendy "world model" label. He argues that the industry should prioritize concrete goals over buzzwords. His goal is to create robots that can perform a vast range of unseen tasks with high speed and success rates, without needing task-specific training data. Recently, his company raised $400 million (¥2.7 billion) at a $2 billion valuation. Notable investors include NVIDIA's NVentures, Bezos Expeditions, NFDG, as well as Xiaomi co-founder Lin Bin, Zoom founder Eric Yuan, and renowned AI scientist Fei-Fei Li. Florence's approach stems from his academic background at MIT under Professor Russ Tedrake, focusing on understanding the physical world. After joining DeepMind, he developed models like Transporter Network and co-created the VLA framework. He left in 2025 to found Generalist AI. The company has launched two models: GEN-0, which demonstrated that scaling laws apply to physical motion, and GEN-1. GEN-1 was trained on over 500,000 hours of physical interaction data collected via a specialized wearable device. It achieves a 99% success rate on precise mechanical tasks like folding boxes and maintains performance three times faster than its predecessor. Florence believes GEN-1 is reaching a commercial utility threshold similar to the GPT-3 inflection point. The substantial funding round, following GEN-1's release, signifies strong investor confidence in Generalist AI's practical, goal-driven path to creating versatile, useful robots, regardless of the "world model" terminology.

Two Legends Lost in Three Days: Is Google's AI Talent Dam Cracking?

In three days, Google lost two AI legends. On June 18, Noam Shazeer, co-author of the seminal "Attention is All You Need" paper and Gemini co-lead, left for OpenAI. Just 48 hours later, John Jumper, 2024 Nobel laureate and AlphaFold lead, departed DeepMind for Anthropic. This follows Andrej Karpathy joining Anthropic in May. These moves highlight a structural trend: top AI talent is concentrating at mission-driven, pre-IPO firms like OpenAI and Anthropic, while Google becomes a primary source. The exodus stems from a core mission mismatch. Google's ad-centric model often subordinates AI research to product and revenue goals, creating friction for pioneers like Shazeer, who returned in 2024 only to leave again. In contrast, OpenAI and Anthropic offer singular focus on pushing AI boundaries, whether towards AGI or safety-aligned models, which deeply appeals to top researchers like Jumper. Financial incentives amplify the pull. With both OpenAI and Anthropic nearing IPO, employees stand to gain immensely from equity, an upside Google's mature stock cannot match. Furthermore, the 2023 merger of Google Brain and DeepMind, intended to consolidate strength, has instead created cultural tension and slowed the path from research to product, as evidenced by Gemini's pace. This talent redistribution is reshaping the AI landscape. While Google retains vast data and compute resources, its true crisis is the quiet, continuous loss of the people who define the field's future. The real moat in AI is not infrastructure, but the concentration of brilliant minds—a battle Google is currently losing.

Behind the AI Report Card, Lies a Chinese 'Exam Setter'

Beyond the familiar performance charts like MMLU-Pro and MMMU, which major AI models strive to ace, stands a key "examiner": Chinese-Canadian researcher Wenhu Chen. An assistant professor at the University of Waterloo and founder of TIGERLab, Chen addresses the crucial need for more rigorous AI evaluation. As models like GPT-4 began scoring near-perfect results on older benchmarks like MMLU, it became difficult to distinguish their true capabilities. In response, Chen introduced MMLU-Pro in 2024, featuring harder, more reasoning-focused questions with more answer choices, successfully reintroducing meaningful performance gaps. His work extends to multi-modal evaluation with MMMU and its enhanced version, MMMU-Pro. These benchmarks test a model's ability to understand and reason with complex information from images, charts, and text across diverse academic subjects, exposing the significant challenges even top models face in genuine comprehension. Chen's background in complex QA, table reasoning, and his experience at Google DeepMind on projects like Gemini inform his approach. He understands that effective benchmarks must anticipate how models might "cheat" by memorizing data or avoiding visual analysis. His lab also actively researches video understanding and generation models (e.g., UniVideo, Vamba), ensuring his evaluation work is grounded in practical model-building challenges. Now at Meta's Super Intelligence Lab, Chen continues his focus on multi-modal data and evaluation, representing the deep yet often unseen contributions of Chinese talent in shaping the fundamental tools of the AI industry.
