比特币开发者 Kevin Loaec 警告，若 BIP-110 相关分叉发生，在缺少重放保护的情况下，用户出售分叉链资产可能导致真实 BTC 被同步转移。
Odaily News: The proposed Bitcoin fork is associated with the controversial BIP-110 proposal and could generate duplicate balances on both chains, potentially prompting holders to attempt selling seemingly free fork coins. Since both chains initially accept the same transactions, selling fork coins could trigger a replay attack and simultaneously spend the seller's real Bitcoin on the main chain. Developers have stated that built-in replay protection will be lacking at least until early September, and non-professional users should avoid transferring Bitcoin during the potential fork period.

According to IBTimes, Nobel laureate and "Godfather of AI" Geoffrey Hinton warned at the Ai4 conference in Las Vegas that as AI model capabilities rapidly improve, humans will find it increasingly difficult to exert effective control over them. He stated: "These systems are becoming smarter, and we will see them develop increasingly complex intentions, as well as increasingly strong abilities to escape control." Previously, OpenAI, Anthropic, and Meta successively disclosed that their experimental models accidentally gained internet access in test environments and infiltrated external systems. Hinton pointed out that the above incidents highlight the growing complexity of frontier AI models and warned that a large number of malicious cyber attacks will occur in the future. He estimates that the probability of advanced AI posing an existential threat to humanity is between 10% and 20%, and called on the industry to prioritize potential risks now, rather than waiting for problems to arise before responding.
According to Bloomberg, sources familiar with the matter revealed that the US government department responsible for investigating chip export control violations is currently systematically reviewing the ways Chinese AI companies obtain advanced Nvidia chips through legal channels, with a particular focus on their practice of renting computing power in third countries. This move stems from recent consecutive technical breakthroughs by Chinese AI companies, indicating that they still possess the capability to acquire and use top-tier hardware under US chip export restrictions on China. Analysts believe that this review may drive the US to further tighten regulatory rules on computing power leasing in third countries to plug loopholes in the current export control system.

The wallet received 49.97 BTC back in 2011, when Bitcoin was trading at around $10 per coin.

The newly transferred BTC has not left this address. The transfer comes amid long-term holders rechecking their old storage setups following a major vulnerability exploit in Coldcard hardware wallets.

According to monitoring by on-chain analyst Ai Yi (@ai_9684xtpa), the hacker address that previously attacked the MEV bot Jaredfromsubway.eth and caused over $7.5 million in losses has shown unusual fund activity again after one month. Approximately 10 hours ago, the address used the remaining 2.44 million DAI to buy 1,277 ETH. Analysis suggests that the relevant funds may next be mixed via Tornado Cash, and this asset may also be the hacker's last pending on-chain funds.
