The XRP Ledger recently fixed a payment system vulnerability that could be traced back to 2015. This vulnerability could allow attackers to bypass the system's calculation limits on token exchange amounts through a specially designed payment transaction, generating and spending large amounts of XRP out of thin air, undermining the mechanism that caps the total supply of XRP at 10 billion.It was disclosed that attackers could create hundreds of accounts, allowing these accounts to post offers to exchange a small amount of tokens for a large amount of XRP, and then execute a transaction simultaneously. Due to a flaw in the software's calculation of the total transaction amount, the seller's account could receive the full XRP, while the buyer's account would need to pay almost nothing. Researchers Cayden Liao and Veria AI reported the vulnerability on September 22, and RippleX subsequently reproduced the attack and confirmed that the generated XRP could be used in subsequent transactions. RippleX stated that there is currently no evidence that this vulnerability has been exploited on any public network. The development team released version 3.4.1 of xrpld on September 25 to fix the vulnerability.

Anthropic released Claude Haiku 5.5 on Wednesday, claiming it to be the company's cheapest, fastest, and most capable small model to date. This model is designed for high-volume tasks such as document summarization and database queries, as well as speed-sensitive scenarios like real-time customer service and browser automation. When developers integrate it into their own products, prompts of up to 100,000 tokens are charged at $0.1 per million input tokens and $0.5 per million output tokens, consistent with the pricing of OpenAI's competing small model GPT-6 Luna released on September 22.The corresponding prices for Haiku 4.5 are $1 and $5, with the new prices being 90% lower, and prompts exceeding 100,000 tokens receiving a 50% discount. Since about 90% of requests for the old model fall below this threshold, and Haiku 5.5 has a slightly higher token count, Anthropic estimates an average savings of about 75%. Benchmark tests show that Haiku 5.5 achieved a success rate of 72.4% on OSWorld 2.1, higher than GPT Luna's 48.9%; on Terminal-Bench 4, it scored 39.2%, surpassing Luna's 16.4% and Haiku 4.5's 0%, but lower than Sonnet 5.5's 70.6%.This is the first Haiku model with adjustable effort settings, allowing users to balance cost and answer quality.

On October 7, Google launched the web platform Playground, where users can describe game ideas in natural language and obtain playable, shareable game versions without writing code. Users can also continue to adjust physical effects, rules, characters, or scenes through dialogue and share their creations via links. This tool is currently open to users over 18 in the United States, with creation permissions tiered according to the user's Google AI subscription level.Games in Playground can run in browsers on mobile phones and laptops. Creators can set their works to private or publish them to the community gallery, and all games must pass a security review, with some categories supporting leaderboards and multiplayer modes. Google refers to it as "an early experiment," and the announcement did not disclose pricing or specify which AI models power the tool.The upgrade path points to Unity Spark, and Google stated that Playground will soon integrate this tool to meet the needs of creators requiring professional-level mechanics and high-fidelity 3D. In a joint statement, Google and Unity announced that Spark will launch later this year, with closed testing starting soon. Previously, DeepMind released the Genie model in 2024, and in January, Google opened Project Genie based on Genie 3 to users of the AI Ultra subscription in the United States.

Google released its latest image generation and editing model, Nano Banana 2.1, on October 6, and it has been launched in the Gemini app, AI mode of Google Search, Google Ads, as well as developer tools like Google AI Studio, Flow, and Stitch. This model can generate images from text descriptions and edit existing photos.Google stated that this upgrade focuses on three aspects: visual design, mask-based editing (where only the marked area changes), and subject consistency, meaning that characters or objects retain their original features after multiple edits. In the overall preference test for text-to-image generation, Nano Banana 2.1 scored 1050 ELO points, higher than Nano Banana 2's 990 points and Nano Banana Pro's 935 points. The model can handle up to 14 reference images simultaneously, track 4 characters and 10 objects, and output up to 4K resolution with an aspect ratio of up to 8:1. Developers can also set the thinking time before generation and enable fact-checking based on Google Search and Google Image Search.When called through the Google Developer API, the standard 1K image is priced at $0.0336, about half of Nano Banana 2's $0.067; the 4K image is $0.0756, while the previous generation was $0.151, and bulk tasks can enjoy a 50% discount. The above performance data comes from Google's own testing.

Grayscale Research Director Zach Pandl published an article on September 28, 2026, in the company's column The Stack. The article states that among American investors, Generation Z starts investing at an average age of 19, Millennials at 25, Generation X at 32, and Baby Boomers at 35. Based on a retirement age of 65, Generation Z has an investment horizon of 46 years, which is over 50% longer than the 30-year horizon when Baby Boomers started investing.Zach Pandl: Starting to invest earlier not only benefits from compound interest but also expands the capacity to take on risk. When young, labor capital accounts for a larger proportion of wealth, and a longer horizon means more time to recover from fluctuations, as well as more future income available for continued saving and investing, thereby expanding the lifetime risk budget. He believes that the returns on digital assets are both volatile and potentially asymmetric, making them more suitable for longer and more flexible horizons.Zach Pandl also mentioned that for early investors, the cost of recent volatility may be less than the opportunity cost of missing out on long-term upside. With decades available for rebalancing, adding funds, and compounding across cycles, early starters may allocate a higher proportion to digital assets while keeping their lifetime risk balanced. Starting to invest earlier gives investors more time to absorb fluctuations, potentially enhancing the utility of digital assets in long-term portfolios.

The founder of the general-purpose intelligent agent Manus, Xiao Hong, stated that when Manus was born, Codex and Claude Cowork had not yet appeared in the market, and the product positioning has always been a general-purpose intelligent agent. He likened Manus to a computer-selling business, believing that users may primarily purchase computers for work, but if they cannot watch videos or play games, the experience will be quite limited; therefore, it should not be confined to office tasks.Xiao Hong indicated that videos and games are important scenarios for unleashing creativity, which need to be perfected through the local client Manus Studio. The related videos for Cue are entirely produced by Manus Studio, without using video generation models; instead, the agent first writes the code, which is then converted into video. With the help of cloud computers, Manus can also create online games that support user participation with friends.In terms of infrastructure, Manus cloud computers can provide cloud-based Linux, Mac, and Windows environments. Xiao Hong stated that when the agent operates the computer in the cloud, it will not compete with the user for the local mouse cursor, and he anticipates that individuals will be able to control large-scale computing clusters in the future to satisfy curiosity and conduct experiments and explorations in fields such as mathematics and science. He also described Cue as having an independent phone number, email, payment capability, computer, and sufficient intelligence, and stated that if such agents could be regarded as humans, there might be more changes in upper-level interactions. Xiao Hong mentioned that building product experiences in an overseas open ecosystem is relatively easier, and Manus is actively preparing a domestic version.
