Vitalik updates the EIP-8141 proposal to support quantum-resistant signatures and wallet social recovery.

Beating AI News Flash: OpenAI has optimized ChatGPT subscription usage for GPT-6 Astra. Core product lead Tibo stated that model quality remains unchanged, with subscription quota consumption in some heavy-use scenarios dropping to roughly 1/3 to 1/4 of prior levels. The optimization is explicitly targeted at ChatGPT subscription quotas. OpenAI has not disclosed the specific mechanism, though its wording indicates it is an adjustment to subscription-side usage calculations. Over the past two days, multiple reports of excessive Astra quota consumption have emerged on OpenAI’s GitHub. Some Plus users said they hit usage limits in around 20 minutes, while Pro 20x users reported depleting most of their weekly quota in a single day.

DeFi researcher Ignas posted on X: "After Bankless founder David Hoffman sold his ETH, he reallocated his portfolio to several top-performing tokens, including LIT and ZEC. NEAR also performed well, while only VVV underperformed the broader market. Though the market was rife with FUD (fear, uncertainty, doubt) at the time, and it was near ETH’s bottom, active crypto investors’ goal is always to outperform BTC and ETH. Well done, David." Earlier, Bankless co-founder David Hoffman announced in June that he had liquidated all his ETH holdings and purchased VVV, NEAR, ZEC, HYPE, and LIT.

According to on-chain analyst Ai Yi (@ai_9684xtpa)’s monitoring, Arthur Hayes has once again added to his UNI holdings, building a position worth over $2 million since yesterday. In the past hour, his address 0x6cd…47e21 received 39,000 UNI tokens (valued at $282,000) from FalconX, pushing his total UNI holdings to 284,101 tokens worth $2.007 million, at an average entry price of $7.06. This marks his first large-scale UNI transaction in nine months, and UNI has now become his third-largest on-chain holding.

According to GMGN market data, today’s meme coin market continues rotating between Robinhood Chain and Solana, with capital rapidly switching between high-market-cap leading tokens and new narrative assets. Trading activity on Robinhood Chain remains centered on MEME, BONER, and PONS, while Solana’s meme space is driven by zec and STONK. On Robinhood Chain, PONS became the first token on the chain to challenge a $1 billion market cap yesterday, peaking at $990 million before consolidating at a high level. The meme coin is currently trading at ~$0.801, with a market cap of ~$802 million, a 15.4% 24-hour drop, and $136 million in 24-hour trading volume. MEME surged yesterday, hitting a market cap of ~$174 million before pulling back. It is now priced at ~$0.096, with a market cap of ~$96.5 million, a 118% 24-hour gain, and $108 million in 24-hour volume. BONER has rallied again, with its market cap briefly exceeding $80 million; GMGN data shows its all-time high market cap is ~$89.3 million. The meme coin is trading at ~$0.067, with a market cap of ~$67 million, a 114% 24-hour gain, and $31.3 million in 24-hour volume. Over on the Solana network, zec also boasts high trading activity, with its market cap briefly hitting ~$114 million. The meme coin is priced at ~$1,184, with a market cap of ~$113 million, an 11.8% 24-hour gain, and $90.5 million in 24-hour volume. zec is primarily tied to Zcash/ZEC-related narratives, drawing capital amid broader privacy coin trends and Solana meme coin momentum. Additionally, Solana’s STONK has also seen strong performance, with its market cap briefly hitting ~$191 million. The meme coin is priced at ~$0.165, with a market cap of ~$145 million, a 141% 24-hour gain, and $104 million in 24-hour volume. STONK is linked to the stonkfun ecosystem and stands as one of the most concentrated new trading hotspots on Solana in recent times.

On-chain analyst Ai Yi, operating under the handle @ai_9684xtpa, has detected that trader gnomelabs.eth likely took profit on 4,020 ETH, generating an estimated $2.345 million in gains over the asset’s 21-day holding period. The trader withdrew 6,339 ETH (valued at approximately $12.02 million) from Binance on August 17 at an average price of $1,896.83. Nine hours ago, they deposited 4,020 of those ETH (worth ~$9.97 million) to an exchange at a price of $2,480; a sale at this level would yield a 30.7% return.

Beating AI News: OpenAI Chief Scientist Jakub Pachocki has warned that a core method the company uses to check AI alignment is growing increasingly unreliable. This method, called Chain-of-Thought (CoT) monitoring, works by observing a model’s written reasoning process to spot hidden goals or dangerous thoughts. OpenAI has long heavily relied on CoT monitoring as a key strategy. One major reason it did not release the full Chain-of-Thought for its o1-preview model was to avoid directly training or constraining CoT, which would teach models to hide their true intentions. This approach remains critical for GPT-6 Astra. However, internal evaluations at OpenAI show CoT monitoring is becoming less reliable: models are now better at controlling their reasoning processes and can keep growing more capable even without writing out their reasoning. Pachocki worries that as model capabilities expand, humans may find it increasingly hard to grasp how these models make decisions. He also pointed out that no AI lab has yet solved alignment and monitoring to a level sufficient for full-speed long-term model scaling. Before establishing shared safety thresholds, he urged AI labs to voluntarily slow down progress, and OpenAI may pause further model scaling if necessary.
