According to official news, the prediction market Polymarket announced a significant adjustment to its settlement mechanism for cryptocurrency price fluctuation markets starting from August 7, to protect market integrity. From midnight UTC on that day, the affected markets will no longer settle based on a single price snapshot at a specific time but will instead use a time-weighted average price.Markets of different durations correspond to different TWAP windows: all cryptocurrency 5-minute markets will use a 30-second TWAP, 15-minute markets will use a 60-second TWAP, and 4-hour markets will also use a 60-second TWAP. The previous single snapshot settlement method was prone to price manipulation during periods of low liquidity, and this change is a proactive reinforcement of the market integrity system by Polymarket after facing regulatory scrutiny.To support this transition, Polymarket will inject $1 million in liquidity rewards into all affected markets throughout August. On the technical side, Chainlink TWAP testnet data streams are now available, and mainnet data streams along with Polymarket real-time data stream services will go live on August 4, at which point developers can access TWAP prices directly through Chainlink Data Streams or Polymarket's public WebSocket.

According to Jinshi reports, Microsoft CEO Satya Nadella emphasized that customers must have the ability to switch freely between different AI models, both closed-source and open-source. He stated during a conference call that the number of Microsoft customers using multiple models has quadrupled since the beginning of this year. Nadella pointed out that the system framework should be separate from the models, allowing for the replacement of models at any given time and the use of cutting-edge models.Microsoft has investments in both OpenAI and Anthropic, and has co-signed an open letter supporting open models with companies like NVIDIA and Palantir.

Uniswap founder Hayden Adams posted on the X platform in response to the controversy over the v4 fee switch, clarifying that "the reduction of LP fees" is a misunderstanding; the protocol fees are additive rather than deductive, and LPs still earn 30 basis points per transaction.Regarding the claim that "the protocol takes 25% of LP profits," he stated that on a 30 basis point pool, the protocol fee is 5 basis points, accounting for about 14% of the total transaction fees, and LPs have not lost any of their earnings. Hayden Adams also pointed out that centralized exchanges charge 100 to 200 basis points per transaction, making Uniswap's 5 basis point fee at the 30 basis point level 20 to 40 times cheaper. He also criticized some forked projects that charge 100% transaction fees but use uneven inflation set by token voting to "compensate" LPs.

According to official news, Base Build announced the launch of Base Verify Onchain to address the issue of witch attacks in the blockchain ecosystem. This feature has been launched on the Base Sepolia test network, allowing developers to implement the "one real user, one claim" rule in smart contracts. Base Build stated that traditional airdrop mechanisms are easily manipulated by bulk wallets, and a large number of rewards are often obtained by professional airdrop farmers, while users who genuinely participate in product development can only receive limited benefits.Base Verify Onchain helps project teams identify multiple wallets controlled by the same user by generating a stable identity hash for each real user, without needing to obtain users' names, account information, or other private data. Users can complete verification through existing accounts such as Coinbase, Instagram, X, and TikTok. The system then returns a verified identity credential to the smart contract, which automatically enforces rules such as claim limits, voting restrictions, or quota controls. Currently, Base Verify has been used over 300,000 times and serves collaborative projects such as Base App, Cody, Scratch, and Bracket. Base Build stated that Verify Onchain will provide fairer airdrops, token distributions, governance voting, and user incentive mechanisms for decentralized applications. Developers can use this technology to limit the number of claims per real user, allocate rewards based on real identities, or convert real-world signals into on-chain credibility, thereby reducing the impact of bots and multi-wallet manipulation on the fairness of Web3 applications.

The founder of the Liebit Mining Pool (B.TOP), Jiang Zhuoer, stated in a post that after this round of market trends, he will no longer short ETH and will instead short BTC. He will use WBETH as margin to short an equivalent amount of BTC spot.The reason is: MSTR can foresee that it will not increase its BTC holdings for a long time in the future; BitMine is still buying ETH; combined with the development of RWA and other factors, this bear market may repeat the last one, with BTC and ETH reaching their lowest points at different times. The last round's lowest point for ETH was on June 18, 2022, when ETH was $881.56 and BTC was $17,622, with an exchange rate of 0.05. The last round's lowest point for BTC was on November 21, 2022, when ETH was $1,079.76 and BTC was $15,476, with an exchange rate of 0.0698. In this round, there is a possibility that ETH will reach a low of $1,505.68 on June 6, 2026, so he has decided to short BTC. BTC has already fallen below the rising channel, while ETH is still at the lower edge of the rising channel.

Data center operator Switch announced the official launch of a $2 billion private financing round, led by a16z. According to insiders, Switch's post-financing enterprise valuation (including debt) may approach $50 billion, with an equity value of approximately $19 billion (excluding new investments). a16z is set to invest about $400 million. Additionally, Goldman Sachs and JPMorgan Chase are also assisting in advancing this financing round, which may prepare Switch for an initial public offering (IPO) as early as next year. Currently, related negotiations are still ongoing, and the scale, valuation, and timing of the financing may still be adjusted.Switch is headquartered in Las Vegas and was founded in 2000. It currently operates data centers in Nevada, Michigan, Georgia, and Texas, with a majority stake held by DigitalBridge. DigitalBridge previously privatized Switch in 2022 in a deal valued at approximately $11 billion (including debt) with investors such as IFM Investors.

According to Jinshi reports, the research report from Zhongtai Securities indicates that overall, the market is likely to maintain a clear bottom and a pattern of consolidation in the next week or two. After the important IPO listings, as market uncertainties settle and sentiment improves, the market is expected to welcome a rally towards previous highs/new highs. The subsequent market style will still be technology diffusion rather than style switching.Focus on technology: storage and semiconductor equipment, overseas computing power chains. Storage and semiconductor equipment are currently the most certain directions.Non-technology directions: new energy, AI-related new materials and minor metals, engineering machinery, and brokerage firms. In the new energy sector, the electricity demand driven by AI computing power expansion and the logic of going overseas constitute medium-term support. In terms of AI-related new materials, the price increase spiral for copper-clad laminates (CCL) has already begun. Brokerage firms benefit from IPO participation and active market trading, still presenting opportunities for fluctuations.

On May 14, BNB Chain released the "BSC Post-Quantum Cryptography Migration Report," stating that it has completed the migration testing for quantum-resistant cryptography for transaction signatures and the consensus layer, using the NIST standardized post-quantum signature algorithm ML-DSA-44 (Dilithium) and the pqSTARK aggregation scheme.The report shows that BSC has replaced transaction signatures from ECDSA to ML-DSA-44 and switched consensus voting aggregation from BLS12-381 to pqSTARK to address the potential threats posed by future quantum computing to the existing elliptic curve cryptography system. However, post-quantum signatures also significantly increase the on-chain data volume: the size of a single transaction has increased from about 110 bytes to approximately 2.5KB; the block size in a 2000 TPS scenario has increased from about 130KB to around 2MB; and the TPS in the testing environment has decreased by about 40%-50%.BSC stated that the current network bottleneck mainly comes from the larger transaction data propagation, rather than the consensus protocol itself. Meanwhile, the consensus layer aggregation still maintains high efficiency, with pqSTARK achieving a signature compression ratio of about 43:1, and the additional burden on validators remains within a controllable range. The report concludes that existing technology can achieve "quantum-resistant" deployment for blockchain, but future issues related to network bandwidth and data scalability still need to be addressed.

According to CoinDesk, hardware wallet manufacturer Ledger has suspended its plans to go public in the U.S. due to unfavorable market conditions. Sources say that Ledger had discussions with investment banks such as Goldman Sachs, Jefferies, and Barclays about an IPO in the U.S. this year, with a potential valuation of around $4 billion, but has not yet submitted an S-1 registration document to the SEC. The company is evaluating other options, including private financing.The report points out that after several crypto companies go public in 2025, many institutions, including Kraken, have postponed their IPOs due to weakening token prices, declining trading volumes, and stock market volatility. Additionally, the only crypto-native company that went public in 2026, BitGo, has seen its stock price drop about 36% below its offering price.

According to Onchain Lens monitoring, the whale Loracle.hl has closed positions in TON, BTC, and CL, making a profit of 3.9 million dollars, while also closing about 96% of its ZEC long positions.Meanwhile, this address has increased its short position of 1.2398 million HYPE by 5 times to a value of 53.23 million dollars, with the current total accumulated profit nearing 37 million dollars.

In response to KelpDAO's accusations against LayerZero regarding the rsETH security incident, LayerZero CEO Bryan Pellegrino tweeted a detailed response, stating that much of the content is completely false.Bryan pointed out that KelpDAO initially used LayerZero's default MultiDVN or DeadDVN configuration and later manually migrated to the 1/1 configuration; under the 1/1 configuration, almost 100% of the transaction volume came from rsETH; LayerZero's documentation repeatedly states that the 1/1 configuration is not recommended for production environments and provides specific transaction records and document screenshots as evidence.

According to The Block, after experiencing a bridge attack of approximately $292 million last month, Kelp DAO decided to abandon LayerZero and instead adopt Chainlink's cross-chain infrastructure.Kelp DAO will use the Chainlink Cross-Chain Interoperability Protocol, which requires 16 independent node operators to validate cross-chain transactions, becoming the first major protocol to leave LayerZero after the attack. During the attack, the LayerZero-driven OFT bridge used a 1-of-1 single validator configuration, with 47% of LayerZero applications using the same configuration at that time. LayerZero subsequently announced the cessation of single validator configurations.Kelp DAO stated that migrating to Chainlink CCIP directly addresses the architectural vulnerabilities in the attack. rsETH will also adopt a cross-chain token standard. As part of the DeFi United rescue operation, LayerZero has donated and lent approximately 10,000 ETH to Aave.
