The SEC will decide whether the cryptocurrency ETF applications will be confidential and the speed of the review: Grayscale, A16z, and others have differing positions from Jane Street and Charles Schwab

The U.S. Securities and Exchange Commission (SEC) has publicly released its request for comments regarding "Novel ETFs," which may hold crypto assets or adopt unconventional strategies. The disagreement centers on whether the filing documents should remain public before the fund begins trading and how quickly the review process should be. Crypto asset management firm Grayscale and the crypto policy organization Crypto Council for Innovation (CCI) support establishing an optional confidential filing period to reduce competitors from submitting imitation documents.Charles Schwab opposes complete confidentiality and suggests that filing documents should be made public at least 75 days in advance. Grayscale requests that the SEC respond within 45 days, while CCI argues that the confidentiality process should not extend the automatic effectiveness or review period. Venture capital firm Andreessen Horowitz (A16z) supports shortening the review time but emphasizes that the rigor of the review should not be reduced; trading firm Jane Street believes that accelerating the process could lead to a decline in product quality, competitiveness, and liquidity.Currently, there are 174 ETFs related to crypto assets in the U.S., with BlackRock's iShares Bitcoin Trust ETF (IBIT) managing approximately $61 billion in assets, accounting for about 38% of the total assets of related ETFs. The SEC will decide whether to adjust the confidentiality arrangements for filings and the speed of the review.

The Ontology mainnet has suspended block production due to a security review, and user assets have not been affected

According to the Ontology blog, its core development team discovered potential security vulnerabilities during routine security checks. Due to a high emphasis on the security and integrity of the mainnet, Ontology has immediately suspended block production on the Ontology mainnet to allow the technical team and validators to conduct a comprehensive security review of the network and related components. Ontology stated that no security incidents have been confirmed at this time, and there are no indications that user assets have been lost or stolen. ONT, ONG, and other on-chain assets are currently assessed to be unaffected; this suspension is a preventive security measure rather than a response to confirmed asset losses or ongoing attacks.During the review period, block production will remain suspended, and on-chain transactions cannot be processed. Users do not need to transfer or take any action regarding their ONT, ONG, and other on-chain assets, but should avoid conducting time-sensitive on-chain transactions until the network officially confirms its restoration. The duration of the suspension has not yet been determined, and the team will prioritize the comprehensiveness of the security review over speed; block production will not resume until the network has been thoroughly assessed and confirmed to be secure. The Ontology team is collaborating with validators and ecosystem partners to address this matter and will update progress through official channels, with a separate announcement to be made before and after the network restoration.

MANTRA announces the review of the attack incident: A down-scaling vulnerability led to the transfer of over 720 million tokens, with approximately 37.96 million tokens frozen

On August 20, MANTRA Chain released a complete review report of the security incident, confirming that the attacker exploited an unsigned integer underflow vulnerability in the balance accounting layer of the upstream dependency cosmos/evm, unauthorizedly transferring a total of 720,923,967.99 MANTRA from two addresses, valued at approximately 3.6 million dollars based on the price before the attack. Among them, the attacker transferred 600,000,035.56 MANTRA from the on-chain burn address and 120,923,932.44 MANTRA from a genesis-era multi-signature address related to an early incentive program.MANTRA stated that this incident did not involve the leakage of validator keys, administrator privileges, governance control, or multi-signature signers; the attacker did not require privileged access and could complete the attack solely through unauthorized contract deployment and self-funded wallets. The first abnormal transfer occurred at 19:06 UTC on August 20, when the attacker transferred approximately 600 million MANTRA from the burn address; subsequently, at 22:59 UTC, another transfer of approximately 120.9 million MANTRA was made. The chain subsequently stopped operating at 23:13 UTC and resumed after upgrading to v8.4.0. The entire network interruption lasted for 30 hours and 13 minutes.This vulnerability was not an issue with MANTRA's self-developed code but originated from the cosmos/evm module, which is responsible for providing EVM functionality on the Cosmos SDK. The vulnerability allowed the attacker to execute unsigned balance deductions without checking if the balance was sufficient, causing an overflow of values and bypassing normal account authorization logic. MANTRA stated that as of today, no funds have been recovered, with approximately 37.96 million MANTRA (accounting for 5.27% of the total transferred) still remaining in the attacker's address, which has been frozen due to the chain's suspension and v8.4.0 restrictions. The remaining funds have flowed to related trading platforms, and the recovery efforts have entered the law enforcement investigation stage. In the future, monitoring of accounts that cannot normally authorize transfers, burn addresses, and other historically "non-transferable" addresses will be strengthened, and efforts will be made to promote improvements in the security vulnerability disclosure process within the Cosmos ecosystem.

first_img Tencent Hunyuan releases and open-sources Hy4 preview, with a total of 770B parameters and 49B activated

Tencent Hunyuan has released and open-sourced the next-generation large language model Hy4 preview. This model has a total of 770B parameters and 49B active parameters, with a context length exceeding 1M. It demonstrates strong capabilities in real productivity tasks such as coding, office work, and science, firmly placing it in the top tier of open-source models. Hy4 preview significantly expands in model size, context length, and data scale, and enhances real-world performance through high-quality data co-built with Tencent experts in software engineering, gaming, finance, security, and deep collaboration with products like WorkBuddy.In software engineering, the model enhances understanding, planning, debugging, and verification capabilities for long-range development tasks, enabling the construction of complex front-end projects like a Three.js miniature town from scratch. In game development, it supports generating playable prototypes from a single sentence and can complete a full demo in Unity. In smart office applications, it can handle complex financial audits, filtering, analyzing, and delivering from multiple documents. In scientific research, it achieves acceleration in tasks such as molecular dynamics simulations and has initially formed a recursive self-improvement feedback loop.Hy4 preview can be experienced in Tencent products such as WorkBuddy/CodeBuddy domestic and international versions, Yuanbao, ima, and can also be accessed via API calls through Tencent Cloud Tokenhub and OpenRouter. WorkBuddy/CodeBuddy will launch a limited-time free activity for two weeks. Since the reconstruction of the infrastructure, the Hunyuan large model has iterated a major version approximately every two months, continuously optimizing through a preview-first and formal version-following approach.
