Linera Launches Babbage Testnet

British man Chris lost access to his digital wallet when crypto exchange Intersango collapsed in 2014. The wallet held Bitcoin worth around ￡4,000 at the time, and the platform had more than 5,000 accounts back then. It is believed that hundreds of millions of pounds worth of Bitcoin may still be held in the account of one of the exchange’s co-founders, with former users potentially able to reclaim their funds if they can provide sufficient proof of ownership. After years of failed attempts to contact the company, Chris gave up at one point, saying watching Bitcoin’s price keep climbing felt “like a punch to the gut”. But earlier this year, he tried again, hiring a lawyer to help prove he owned dozens of the “lost” Bitcoin. A few months later, the Bitcoin was returned to him — now valued at around ￡3.3 million.

According to YuEjin Monitoring, Pump.fun transferred 132,937 SOL (worth approximately $13.74 million) in fee revenue to Kraken 20 minutes ago.

Fed Chair Walsh stated that U.S. economic growth appears to have picked up somewhat.

Well-known trader Killa stated in a post that Bitcoin will hit a new all-time high next year, and it won’t even matter if you end up buying at $100,000. These price levels will all be left behind as time passes, and the biggest mistake is staying on the sidelines.

Beating AI Express News: OpenAI’s ad business has hit $1 billion in annualized revenue. ChatGPT Ads launched less than 200 days ago, and is already used by tens of thousands of advertisers, with ads covering over 40 countries. The ads are also accelerating expansion from the U.S. to global markets; advertisers in India, Europe, the Middle East, and North Africa can now self-serve directly via Ads Manager. OpenAI added that small and medium-sized enterprises (SMEs) have contributed a significant portion of the ad business’s revenue. ChatGPT Ads primarily target Free and Go tier users. Ads are matched based on the current conversation context; in some regions, with user consent, they may also reference broader ChatGPT usage history. OpenAI clarified that ads are displayed separately from responses, do not interfere with ChatGPT’s answers, and advertisers cannot access users’ private conversations.

From 动察 Beating AI News: The Information, citing two people familiar with the matter, reports that Changxin Memory has commenced small-batch production of HBM3E, with plans to expand output in 2027. HBM (High Bandwidth Memory) is high-speed memory placed alongside AI chips, tasked with delivering data to the chips at high speeds. Since 2024, the U.S. has restricted exports of HBM2 and higher generations to China, making HBM a key bottleneck for domestic AI chips. Domestic chip developers including Cambricon and Alibaba's T-head are testing Changxin's HBM; if progress continues smoothly, it could be integrated into products as early as next year. HBM3E is the memory generation used by Nvidia's H200 and Blackwell chips. By product generation, Changxin is currently only one generation behind SK hynix, Samsung, and Micron, which are mass-producing HBM4. However, small-batch production is a long way from mature mass production. Changxin's HBM3E still has low yield, and lags behind the three major manufacturers in speed and reliability. SK hynix began mass-producing HBM3E as early as 2024; the three majors have now entered the HBM4 phase and started sampling HBM4E. Changxin has cleared the hurdle of "can we produce it", and the next challenge is to significantly improve yield and output.
