US inflation remained sticky in July, while the country’s second-quarter GDP growth rate held steady at 1.5%.

According to market data from BIT (bit.com), Meta Platforms (META) has turned negative, after earlier gaining more than 3%.

Beating AI Express (from Dongcha Insight): Tencent WeChat’s Computer Vision team has open-sourced WeMM-Embedding, releasing three multimodal embedding models in one go: 2B, 4B, and 9B parameters. Built on Qwen3.5, these models can convert text, images, videos, and visual documents into unified vectors for applications including search, recommendation, and content matching. All models are open-sourced under the Apache 2.0 license. Notably, Alibaba’s Qwen has not yet launched its own Qwen3.5-Embedding; its official existing offerings remain Qwen3-Embedding and Qwen3-VL-Embedding, while Tencent has taken the lead in developing a new generation of embeddings based on Qwen3.5. The performance is quite impressive: WeMM-Embedding 2B scores 77.9 on MMEB-v2, slightly outperforming Qwen3-VL-Embedding 8B’s 77.8 points, while the 9B version further reaches 80.6 points. Both models support cross-modal retrieval such as text-to-video search and image-to-text search, but WeMM, built on the Qwen3.5 base, achieves higher performance with a smaller model size. These models have already been deployed for internal use within WeChat. Tencent confirmed that they are currently used in WeChat Official Accounts, Video Channels, e-commerce recommendations, and WeChat Search, with the search scope extending to Moments.

According to market data from BIT (bit.com), U.S. stocks opened with the Dow Jones Industrial Average down 0.19%, the S&P 500 down 0.02%, and the Nasdaq down 0.22%. Meta Platforms (META) rose approximately 3% after the company agreed to settle allegations that its platform harmed children.

According to market data from BIT (bit.com), all crypto-related stocks declined when US stocks opened on Wednesday. The individual stock performances are as follows: Gemini (GEMI) fell 4.37%, American Bitcoin (ABTC) dropped 4.35%, MARA slid 3.64%, Strategy (MSTR) decreased 3.55%, Coinbase (COIN) dipped 3.13%, Riot Platforms (RIOT) fell 2.77%, Bullish (BLSH) dropped 2.59%, Robinhood (HOOD) declined 2.27%, BitMine (BMNR) slid 1.73%, and Circle (CRCL) fell 1.70%.

Ethereum researchers have released an early draft proposing to restructure the validator deposit contract to support varying key lengths and multiple cryptographic signature schemes, laying the groundwork for future adoption of post-quantum signatures. The existing contract hardcodes BLS key sizes, meaning even if developers identify new post-quantum schemes, the network cannot currently integrate them directly. The draft will tag each deposit with the cryptographic system used, assigning tag 0 to BLS and reserving all other tags for future schemes. If approved, new signature schemes can be integrated alongside BLS; Ethereum could later vote to permanently stop accepting new BLS deposits, though validators already staking with BLS keys will not exit immediately. The draft currently uses a temporary identifier, with maintainers suggesting it be designated EIP-8394. As of Wednesday, roughly 42.4 million ETH is staked on Ethereum, valued at approximately $104 billion, all secured by BLS validator keys. In March this year, Google Quantum AI outlined 5 potential quantum attack vectors targeting Ethereum, impacting over $100 billion in assets across wallets, staking, smart contracts, and Layer 2 networks. The Ethereum Foundation currently plans to complete core protocol-level adjustments related to this by around 2029.
