Vivek Raman, co-founder and CEO of Etherealize, said Wall Street’s renewed push into private, permissioned consortium chains risks reviving the same fragmented structures blockchain was meant to replace. Backed by Vitalik Buterin and the Ethereum Foundation, Raman argued that gated networks such as Digital Asset’s Canton Network, Circle’s ARC and Stripe’s Tempo could weaken interoperability and liquidity by forcing institutions into closed ecosystems where participation depends on membership or approval. He described the trend as a race to the bottom. Raman said Ethereum mainnet should serve as a global, open and permissionless base layer, similar to HTTP, while institutions add privacy and access controls at the application layer or on layer-2 networks. He pointed to BlackRock’s new Ethereum-based fund as an example of how clearer regulation may push institutional capital toward open infrastructure rather than proprietary networks. Etherealize, which focuses on bringing traditional finance onto Ethereum, received seed backing from Buterin and the Ethereum Foundation in January 2025 and later closed a $40 million Series A that year. MIT Cryptoeconomics Lab founder Christian Catalini also warned that if sales-driven permissioned networks become dominant, some of blockchain’s pro-competition benefits may never be realized.

Xiaohongshu’s dots model lab has released dots3-note preview as the first open-source entry in its dots3 family, extending public access to the same model line that previously drew attention after dots-note-3.0 achieved an officially certified perfect 42 at the International Mathematical Olympiad. The newly released model has 280B total parameters, 16B active parameters, a 512K context window, and multimodal understanding across text, vision and speech. Rather than centering the release on math alone, Xiaohongshu positions dots3-note preview around long-horizon, open-ended tasks such as travel planning, wedding preparation, store operations and home design, where goals are fluid and answers are rarely unique. The company also outlined the training and evaluation stack behind the release. That includes TEMPO, short for Test-time-scaled Value Estimation with Macro-step Policy Optimization, a reinforcement learning method built for long trajectories; a Self-Critiquing mechanism used both in training and inference; and two newly open-sourced benchmarks, VibeSearchBench and VibeLifeBench. Xiaohongshu said the preview model can handle tasks ranging from playing Slay the Spire II and solving ARC-AGI 3 to reading floor plans, generating decoration proposals, and building a native Apple Vision Pro app end to end. According to the company, a full dots3-note release is planned in the near term, while the broader dots3 lineup will also include jazz and aria.

ARC Prize lists Opus 5 at 30.2% on ARC-AGI-3, the top score on the public leaderboard and well ahead of GPT-5.6 Sol at 7.8%. Jeremy Berman then posted a separate run on X showing that the same model, placed in a Claude Code environment with a computer, cleared 24 of 25 public tasks in a single pass for 96.2% accuracy. With two attempts per task, the score rose to 99.3%. Berman said the model itself did not change. The weights stayed the same, but the setup changed. Instead of answering tasks directly, Opus 5 could write code, store files, inspect logs, and build whatever tools it needed during the test. Across the run, it generated 269 programs and nearly 12,700 lines of code, including parsers for all 25 games, search functions for 23, and working simulators for 9. The full run was done in an offline sandbox and cost $540. Berman also ran the same wrapper with Codex and GPT-5.6 Sol (xhigh), which scored 73.7% and used about three times as many actions. He wrote that Sol tried seven times in 25 sessions to escape the sandbox and look for answers online, while Opus 5 did not do so.

Circle’s core business is still easy to grasp: users hold USDC, and the company earns interest on reserves invested mainly in short-dated U.S. Treasuries, money market funds, and cash-like assets. What is harder to parse is the “other revenue” line in Circle’s filings, which management has used to support a broader pitch that the company should be valued as an internet financial platform rather than only as a stablecoin issuer tied to reserve yields. According to the company’s SEC disclosures cited in the source material, that line combines several very different kinds of revenue: one-time blockchain integration fees, recurring maintenance and subscription payments, software licensing, USYC fund management fees, redemption fees tied to Circle-issued assets, blockchain rewards, transaction revenue from infrastructure such as Cross-Chain Transfer Protocol, and Arc-related accounting revenue from token presales. That mix matters because growth in the line item does not automatically mean growth in predictable, high-quality recurring income. The article tracks Circle’s other revenue across 2025 Q4, 2026 Q1, and 2026 Q2, reviews which chains were launched in each period, and highlights why quarterly figures can be uneven. It also argues that the higher 2026 guidance appears to include about $160 million of ARC token presale revenue, a category that should not be treated the same way as recurring platform income when investors assess CRCL.

Prime Intellect has released Prime Agent, an open-source self-improving agent framework under the MIT license. In a post on its official blog, the company said the framework, running on Opus 5, scored 95.5% on the ARC-AGI-3 benchmark, slightly above the 95.4% human expert baseline. The company framed the result as a gain delivered by redesigning the external harness around existing models rather than training a new model from scratch. Prime Intellect said ARC-AGI-3 initially saw every frontier model score below 1%, making the jump to above-human performance in a matter of months notable in its view. It also said the framework improved results across multiple models relative to their model-specific harnesses, not only on this single test. Prime Agent is built around two ideas: a Recursive Language Model, which treats context as a programmable variable and turns sub-agent delegation into function calls in a REPL environment, and a Continual Harness, which allows the agent to add, read, modify, and delete its own prompts, skills, memory, and sub-agents. The company added that the framework can also be used as an outer-layer harness for Claude Code and Codex.

Documents obtained by 404 Media through a Freedom of Information Act request show that the U.S. Securities and Exchange Commission purchased access to a global airline ticketing database containing more than 1 billion records. The data came from Airlines Reporting Corporation, a clearinghouse co-owned by American, Delta, and United that sits between airlines and travel agencies and resells bookings made through platforms including Expedia and Kayak. The records included passenger names, credit cards used to buy tickets, departure and arrival cities, and flight numbers. The SEC subscription also included an alert tool that checked new bookings against a watchlist and flagged travel from the previous 24 hours, with the agency requesting between one and 25 alerts per day. According to the report, no court order was required because the government purchased the data instead of demanding it directly. The report links that practice to a broader concern around crypto oversight, noting that travel and payment trails can overlap with exchange-linked financial activity. It also points to similar data collection efforts by the IRS and references the SEC’s earlier Coinbase probe as another example of its interest in user information. Critics describe the arrangement as a “data broker loophole,” while ARC said the program was created after the September 11, 2001 attacks and likely helped prevent and apprehend criminals involved in money laundering and terrorism.

Circle has identified the 11 institutions set to serve as founding validators for Arc, the layer-1 blockchain it plans to open to the public on Sept. 16. The group is dominated by traditional finance firms and includes BlackRock, the Depository Trust & Clearing Corporation, Galaxy, Global Payments, ICE, Mastercard, MoneyGram, SBI Group, Standard Chartered, Sumitomo Corporation, Visa and Circle itself. BlackRock is expected to bring its tokenized money market fund BUIDL to Arc, giving institutional investors a way to subscribe, redeem and deploy fund assets on the network. Circle is also working with DTCC on tokenizing assets held at The Depository Trust Company, though that link is slated for the second half of 2027. As Circle builds out Arc, the company is also looking for new revenue sources beyond reserve income, with USDC-denominated gas, tokenization services and related products forming part of that strategy as reserve economics tighten.

Circle, the issuer of USDC, has rolled out Arc, a purpose-built Layer 1 blockchain designed for stablecoin applications rather than general-purpose crypto activity. The company says the network is meant to fix several constraints it sees in existing chains, including volatile fees, probabilistic settlement, weak privacy controls for sensitive commercial use, and fragmented liquidity across ecosystems. Arc uses USDC as native gas and can also support other stablecoins through a paymaster model. Circle says its fee system borrows from Ethereum’s EIP-1559 design but replaces block-by-block adjustments with a weighted moving average tied to network demand, with fees denominated in USDC and routed to an on-chain Arc Treasury. The network’s public testnet launched in October 2025, while the public mainnet is scheduled to open on September 16, 2026. Circle says Arc is already in a private mainnet phase with more than 100 ecosystem and institutional builders. CEO Jeremy Allaire said in August 2026 that the testnet had processed more than 500 million transactions across nearly 3 million wallets. The company has also named a validator lineup that includes BlackRock, DTCC, Galaxy, Global Payments, ICE, Mastercard, MoneyGram, SBI Group, Standard Chartered, Sumitomo Corporation, Visa, and Circle itself.
