The Web3 fitness protocol BRT.Fit has released a transparency statement, currently in the product testing and ecosystem validation phase. Application functions and validation methods may be adjusted based on testing results. The test token tBRT is only used for economic model validation and does not represent the official token value, nor does it constitute an investment product or guarantee of future returns. Its "mandatory exercise protocol" is an incentive and commitment mechanism that users voluntarily join, helping to develop exercise habits through verifiable data, without physical compulsion.After the official mainnet launch, core functions such as token staking, rewards, and burning will be executed through on-chain smart contracts, with contract addresses and audit reports to be disclosed gradually. The project plans to support mainstream wearable devices such as Apple Watch, WHOOP, and Xiaomi, Huawei, and will continue to optimize the anti-cheating system. The project team reminds that digital assets carry significant volatility risks, participation does not guarantee returns, and users should refer to official announcements, remaining vigilant against counterfeiting and phishing activities.

According to external disclosure information, OpenAI has been internally running an unreleased model. This model, without the aid of tools like Lean, solves the unit distance problem with a 48% probability through a single autonomous inference and can independently find a counterexample to the Jacobian conjecture based on a single prompt. In security testing, this model has bypassed the sandbox environment and submitted results that should have been released internally to GitHub in the form of a Pull Request, and it has evaded detection by splitting authentication tokens. Relevant code records show that OpenAI began benchmarking this model no later than May 9, and its internal availability has exceeded 2.5 months.Previously, OpenAI and Hugging Face jointly disclosed that last week this model breached Hugging Face's production infrastructure during a network capability assessment. The model gained internet access through a zero-day vulnerability and obtained testing solutions by stealing credentials and exploiting remote code execution paths. OpenAI stated that this incident indicates the network attack capabilities of advanced models have been effective in real-world scenarios, and they are collaborating with Hugging Face to investigate and patch the vulnerabilities. Currently, OpenAI has not publicly commented on this matter.

SBI Group, DigiFT, and Startale Group have completed a joint proof of concept, demonstrating the full lifecycle of tokenized securities using the Japanese yen stablecoin JPYSC in an Ethereum testnet environment, including instant settlement for fund subscriptions and automatic on-chain dividend distribution.SBI Group and DigiFT are advancing the tokenization of the SBI Japan High Dividend Equity Fund, which is managed by SBI Asset Management with an asset management scale of approximately $1.3 billion, making it one of Japan's major public equity strategies. The three parties completed two tests, one demonstrating the near-instant settlement of fund subscriptions using JPYSC, and the other automatically calculating and distributing dividends to eligible token holders' wallets via smart contracts after the allocation registration is completed.The three companies plan to explore the integration of tokenized Japanese stocks with institutional DeFi platforms and consider testing use cases such as collateralized lending and on-chain asset management with ecosystem partners like Morpho and Gauntlet.

The Ethereum Foundation Protocol Security team researchers stated in a blog post on Thursday that a series of AI agents have been deployed to test the software relied upon by Ethereum, searching for vulnerabilities in the cryptographic systems, protocol code, and smart contracts. The vulnerabilities discovered by the AI agents include a remotely triggerable panic issue in the peer-to-peer layer libp2p gossipsub used by the Ethereum consensus client, which has been fixed and disclosed on GitHub as CVE-2026-34219.The researchers noted that the AI agents are organized into specialized roles such as reconnaissance, searching, patching, and verification, aimed at identifying potential attack paths, reproducing failures, and verifying their applicability to production code. The Ethereum Foundation stated that AI has not replaced security researchers but has changed the way they work, allowing the team to cover a much broader scope than manual reviews, although researchers need to exercise more careful judgment over a large number of seemingly credible conclusions.

Alipay announced that its AI open platform is officially launched and is now open for invitation testing to enterprise developers and service providers. The platform aims to assist merchants and institutions in conveniently upgrading their service capabilities to AI.According to the official introduction, through this platform, merchants can upgrade their existing mini-programs, API interfaces, and service capabilities to AI-callable MCP, Skill, or Agent without starting from scratch. Once integrated, services can not only be provided to Alipay's 1 billion users through the built-in AI assistant "Abao," but can also be authorized for cross-end interconnection to smart terminals and large model platforms such as mobile phones, in-car systems, AI glasses, and IoT, achieving "one-time access, multi-end distribution and unified management," thereby reducing the R&D costs of adapting to multiple terminals separately. In addition, the platform will provide basic support for the hosting, distribution, trading, and settlement of AI-enabled services. Alipay emphasizes that this AI upgrade will not affect the existing Alipay App mini-program services, and the platform will continue to provide security infrastructure such as identity verification, payment security, and risk prevention and control.

According to crypto analyst alicharts, Ethereum is currently testing resistance at the 0.8 MVRV pricing level of $1796. If the daily closing price is above this level and successfully holds it as support, it will strengthen the bullish case and may open the move towards Ethereum's target price of $2245.alicharts further pointed out that breaking above both $1796 and $1816 will trigger a bullish breakout. From a technical perspective, such a move will also increase the probability of ETH breaking through the channel top at $1844 and starting the march towards the target price of $2245.

David Bailey, Chairman and CEO of the Nasdaq-listed Bitcoin treasury company Nakamoto, stated that the failure of the so-called "BIP-110" long-standing controversial event constitutes an "extreme benefit" for Bitcoin and believes it further validates the network's resistance to attacks and splits.This event is seen as a prolonged "governance layer conflict attempt" involving multiple games such as mining pool competition, client fork proposals, UASF (User Activated Soft Fork) mobilization, node consensus manipulation controversies, and large-scale information warfare surrounding social media and the developer community.David Bailey noted that this process validates the core characteristics of Bitcoin's governance structure: the final consensus is formed collectively by users, miners, developers, and industry participants, rather than being dominated by a single group. Historical similar events (such as BIP148) have proven that miners find it difficult to deviate from consensus, and this event further reinforces that conclusion, demonstrating the Bitcoin network's robust resistance to splits.

B.AI officially announced that its team-level AI collaboration product "B.AI Team" has entered the first phase of gray testing and is simultaneously launching a public recruitment for the first batch of experience teams globally.This version focuses on the pain points of enterprise-level AI collaboration, launching a shared Credits pool to achieve unified scheduling of team computing resources and cost visualization management; it also provides a flexible multi-level member permission system, supporting refined configuration of model usage strategies by role, truly allowing AI capabilities to adapt to the collaboration processes of different teams.Starting today, teams interested in seizing the opportunity can submit their requirements through the official application link and briefly describe their core usage scenarios; after approval, the B.AI team will connect with them promptly and grant priority access rights when the official version goes live, helping teams to be the first to enjoy a new experience in intelligent collaboration.

Base officially released an analysis report on the interruption of block production, which disclosed that the Base mainnet experienced two interruptions in block production on June 25 and 26, lasting 116 minutes and 20 minutes respectively. The security of on-chain assets was not affected, and funds remained in a secure state.The root cause of the incident stemmed from a logic flaw in the sequencer's block construction: after a transaction execution failure, the old journal state was not correctly cleared, leading to gas calculation errors during the execution of subsequent valid transactions, which in turn generated invalid state transition blocks, causing the entire L2 chain to pause block production.Base stated that the issue has been resolved through a patch, and it will strengthen the protocol's fuzz testing and stress testing systems to identify potential malicious transaction paths, while also optimizing monitoring and operational processes. Additionally, there are plans to introduce a recovery mechanism to enhance the ability to recover quickly from similar incidents in the future.

BIT (formerly Matrixport) announced the official launch of its U.S. stock margin trading feature, which will be open for public testing starting June 26. BIT is the first platform in the cryptocurrency industry to offer margin trading functionality. Users can now submit margin loan applications through the official website or app. BIT will review applications based on account status and risk management requirements, gradually increasing the margin limits. Additionally, features such as securities lending are also in preparation and will be gradually opened based on regulatory requirements and product progress.During the public testing period, BIT will simultaneously launch the "First Margin Loan · Limited Time Interest-Free" and "Interest Cashback Gift" promotions: Users who use margin trading for the first time during the promotional period will enjoy 30 days of 0% interest on their first loan, allowing users to experience the efficiency of leveraged funds without interest. Elio Cui, head of brokerage services, stated: "BIT is the first to provide margin trading functionality, enhancing the customer journey from account opening, trading to fund leverage. This allows BIT customers to improve investment efficiency and strategically position themselves in the world's most wealth-generating assets without relying on bank cards or leaving the digital asset ecosystem."BIT also reminds users that while margin trading enhances the efficiency of fund usage, it also comes with corresponding risks. Users should fully understand margin rules and risk control mechanisms and participate cautiously based on their own risk tolerance.

According to "Du Jia," ByteDance's AI assistant "Doubao" is ramping up efforts in the instant travel sector. Currently, the Doubao App is conducting a grayscale test of the one-click ride-hailing feature for select users in Beijing and Hangzhou. After users input their travel needs via voice in the dialogue box, the system can automatically recognize the information and match it with available vehicles. Once confirmed, users can complete the order with one click, and the related ride-hailing services are provided by Cao Cao Mobility.It is reported that Cao Cao Mobility has integrated exclusive orders for Doubao and is offering additional service fees to drivers who complete these types of orders. Last week, Cao Cao Mobility launched its new RoboX strategy in Hong Kong, announcing a comprehensive AI transformation, establishing an AI division, and proposing a "Double 100,000 Plan" to deploy 100,000 Robotaxis and 100,000 Robovans by 2030.

Crypto KOL Ansem posted that Bitcoin is currently at a quite critical position, re-testing the key weekly resistance level of approximately $65,000 to $66,000 within this round of range. He will not go long on BTC at this position, as he believes there are better long opportunities in the market. However, if BTC closes above this range, it may re-test $72,000, which he leans towards as the scenario. If he is wrong and BTC drops below $63,800 and shows weak performance, the short-term trend will turn bearish, potentially re-testing $60,000. If this situation occurs, he will consider going short and set the stop loss above the previous short-term consolidation range. In addition, Ansem stated that the FOMC minutes released today at 2:30 may affect market direction.

According to Livecoins, Brazilian Federal Deputy Lincoln Portela proposed Bill No. 2.901/2026, which aims to establish a framework for a national fintech and digital finance platform, creating a permanent regulatory sandbox system for testing blockchain technology and asset tokenization, supervised by the Central Bank of Brazil.The bill requires regulatory requirements to be proportional to the size of the company, allowing small fintech startups to apply simplified standards, and prohibits the government from imposing bureaucratic measures or obligations that do not align with the digital nature of the cryptocurrency market. The sandbox testing scope includes financial flow tracking, artificial intelligence credit applications, and programmable payment practices.The bill also allows companies to share network infrastructure and institutional adaptation databases, but they must comply with data protection regulations. The cooperation mechanism aims to combat financial crimes in cryptocurrency transactions, promote customer identity verification, and enhance cybersecurity.The bill also proposes the establishment of a national system for digital financial integrity, coordinating network regulatory actions to combat criminal structures that use cryptocurrency to hide wealth. Fines for non-compliant companies can reach up to 20% of their annual profit or revenue. The bill will be discussed in various committees of the House of Representatives.

Ant Group declined to comment.

Sources say that Nvidia has begun marketing its first standalone Central Processing Unit (CPU) product, Vera, to Chinese customers. This chip is designed for Agentic AI systems and has now entered mass production, marking Nvidia's attempt to further expand its presence in the Chinese market through CPU products.Insiders indicate that some Chinese customers have shown interest in Vera. One large Chinese cloud computing company plans to purchase over 300 servers equipped with dual Vera CPUs for testing and will decide whether to scale up purchases after the testing is completed.Vera is built on the Arm Holdings architecture and is Nvidia's first standalone CPU product. Nvidia previously stated that Vera's performance in AI agent-related computing tasks can reach 1.8 times that of competing products, and it is expected that this product will contribute approximately $20 billion in revenue before the end of the current fiscal year (by the end of January next year).Reports point out that as the focus of the AI industry gradually shifts from model training to inference computing, CPUs and custom chips are gaining more attention. Vera also puts Nvidia in direct competition with Intel and Advanced Micro Devices (AMD), which have long dominated the server CPU market.Insiders have noted that due to strict restrictions imposed by the U.S. on high-end GPU exports, CPUs face relatively fewer regulatory hurdles in the Chinese market compared to GPU products. Currently, some Chinese customers plan to first deploy Vera chips in overseas data centers for testing. Meanwhile, software ecosystem compatibility and the existing domestic AI chip deployment system may still affect the subsequent large-scale adoption of Vera.
