Renaiss and GIWATER have completed the integration of the TCG card machine application, with the latter becoming the first decentralized exchange (DEX) in South Korea to integrate this application.

Eli Ben-Sasson, one of Zcash (ZEC)’s founding scientists, noted that some people—especially Bitcoin supporters—might not take kindly to his remarks, but he felt compelled to share them. He attributed ZEC’s recent price rally in part to concerns that Bitcoin has grown overly ossified, adding that he himself has a deep affection for and cares greatly about Bitcoin.

Insight Beating AI Flash News: Three white-hat researchers from security firm Hacktron gained access to OpenAI’s internal codebase using Claude in under 72 hours. The trio voluntarily reported the vulnerability, and OpenAI awarded them a $6,500 bounty after patching the flaw. The attack vector was OpenAI’s community forum: the researchers discovered uploading a specially crafted HEIF image could exploit a vulnerability in Discourse (the forum software) to execute arbitrary code on the server. They then obtained login tokens for forum users—essentially "logged-in access passes". A more critical issue lay with OpenAI itself: the forum’s login tokens had overly broad permissions, granting access to the same user’s ChatGPT and Codex accounts, and some tokens belonged to OpenAI employees. The researchers used one employee’s Codex account, which was linked to the company’s GitHub. They ultimately had Codex submit a harmless documentation change to the internal openai/openai codebase to confirm access, then halted testing and reported the incident. Claude handled the most challenging step: converting the image-based vulnerability into functional exploit code. Opus 4.8 was unstable, but the team made breakthroughs just hours after Opus 5 launched. Hacktron noted the entire process—from initial discovery to accessing OpenAI’s internal repository—took less than 72 hours, with only a few hours of actual human work invested.

According to Lookonchain’s monitoring, a total of 11 new wallets suspected to belong to the same crypto whale have sold 602 BTC on Hyperliquid and purchased 18,780 ETH over the past three days. Both transactions are valued at approximately $45.83 million, signaling the whale is rebalancing its portfolio.

Whales are rotating from $BTC into $ETH! Over the past 3 days, 11 newly created wallets (likely belonging to the same whale) sold 602 $BTC ($45.83M) on #Hyperliquid and bought 18,780 $ETH ($45.83M).

VanEck Head of Digital Assets Research Matthew Sigel told CNBC in an interview that Bitcoin could surge to $100,000 next year, as concerns over government debt and fiscal sustainability underpin its price. Bitcoin’s volatility has fallen by roughly 50% compared to four years ago, a clear indicator that this cycle differs significantly from the previous one. Widespread over-indebtedness among global governments has helped Bitcoin maintain its resilience, he added. Sigel also noted that put options are trading at a substantial premium to call options, and the U.S. Treasury’s repurchase (repo) program has triggered a large wave of short covering, making the current time window favorable for Bitcoin bulls. Policymakers are unlikely to resolve unsustainable fiscal conditions, and further easing of market liquidity would provide an even stronger boost to Bitcoin. Discussions between VanEck and institutional clients including investment advisors and sovereign wealth funds show that these entities are all buying Bitcoin. VanEck also forecasts that the stablecoin market will continue to grow. While stablecoin regulation has been enacted into law via the GENIUS Act, banking lobby groups are still attempting to renegotiate the relevant arrangements. Earlier, the U.S. Senate failed to advance the Clarity Act, which aimed to establish a regulatory and market structure framework for crypto assets.
