first_img Tavus claims that the Griffin model causes 48% of video call participants to mistakenly believe they are interacting with a real person

AI startup Tavus released a new model called Griffin on October 1, referring to it as the first "human interaction model" that can understand and generate face-to-face conversations, paying attention not only to wording but also to expressions and pauses. Tavus stated that in tests, after a one-minute video call with Griffin-Lite, 26 out of 54 participants (48%) believed the other party was a real person; its previous generation system only convinced 1 out of 41 participants.Participants were told they would have a one-minute video call with another person to discuss things they were looking forward to this year, and only at the end of the call were they asked if they suspected the other party was not a real person. Tavus noted that those who became suspicious typically noticed within 20 seconds. This result comes from Tavus's own research page, where participants were recruited through a channel they call an independent research platform. Community comments on X pointed out that these results have not been independently verified and do not meet standard protocols.In the NVIDIA VideoFDB benchmark, Tavus claimed Griffin-Lite ranked first, with a generation dimension score of 3.83, the next best system scoring 2.8, and human reference scoring 3.92; the perception dimension score was 3.73, with the strongest baseline at 3.44 and human reference at 4.2. Tavus stated that NVIDIA independently conducted this evaluation. Griffin supports full duplex, allowing it to listen, see, and speak simultaneously, with an average audio-video delay of 0.43 seconds on the NVIDIA H100 chip. Tavus completed a $40 million Series B funding round led by CRV in November 2025.

first_img BNY is in talks with Kraken's parent company Payward for infrastructure cooperation

According to CoinDesk, informed sources revealed that the custody bank giant BNY is in talks with Payward, the parent company of the cryptocurrency exchange Kraken, for a broad collaboration covering digital assets and financial market infrastructure. The potential agreement may involve areas such as crypto products, custody, wealth management, trading, payments, and infrastructure, with related services provided through Payward Services, which targets banks, exchanges, and asset management institutions.One source indicated that part of the proposed collaboration may be similar to the infrastructure component of the recent agreement Payward reached with Nasdaq. Negotiations are still ongoing, and there is no guarantee that an agreement will be reached; both Payward and BNY declined to comment. BNY, formerly known as Bank of New York Mellon, provides custody, asset services, clearing, and wealth management services to institutional clients and has been developing tokenized deposits to support near real-time on-chain settlements among institutional market participants.Reaching an agreement with BNY would further promote Payward's efforts to connect digital asset businesses with traditional financial institutions. Last month, Nasdaq Ventures agreed to invest $100 million in Payward at a valuation of $21 billion, expanding the collaboration between the two parties in tokenized stocks. Under the agreement, both parties will continue to develop the operational and commercial infrastructure for Nasdaq stock tokens, and Payward will also adopt Nasdaq's market surveillance technology in its cryptocurrency, stock, tokenized stock, futures, and options trading venues, with both parties expecting to launch Nasdaq stock tokens in the second quarter of 2027.

first_img Cboe is exploring the launch of VIX perpetual futures, still in the early stages

According to CoinDesk, Cboe is exploring the launch of perpetual futures linked to the VIX index, which is still in the early stages, with no contract specifications yet and no filing documents submitted. This news comes from Bloomberg.The VIX index measures the expected volatility over the next 30 days as reflected by the pricing of S&P 500 options. As investors buy options to hedge against sharp market declines, the demand for options during downturns surges, thereby raising the index, which is why it is regarded as Wall Street's "fear gauge." Perpetual futures were first proposed by economist Robert Shiller in 1993 and were subsequently commercialized by the cryptocurrency industry.A mature derivatives ecosystem has already formed around the VIX, covering futures, options, and exchange-traded products tracking the index. However, futures come with expiration dates, and when contracts terminate, traders must roll over their positions or shift their bets to the next available contract. This rolling operation is costly and erodes returns, which was a major criticism faced by Bitcoin futures ETFs when they debuted at the end of 2021.In contrast, perpetual swaps never settle and instead anchor contract prices to the spot index through a funding rate mechanism, theoretically providing investors with the closest investment channel to the actual VIX spot price. Martin Lee, Head of Market Insights at DWF Labs, told CoinDesk that traders do not need to worry about expiration and value decay, as they can focus solely on assessing the direction of the underlying asset. He expects a strong trend of "perpetualization" to emerge in the coming months.

first_img Spanish police arrested a 16-year-old boy involved in operating the KillSec ransomware group

According to Decrypt, the European Union's law enforcement agency reported that Spanish police arrested a 16-year-old Romanian suspect in Alicante, suspected of being an administrator and main operator of the ransomware group KillSec.Two other suspects in their twenties were arrested in the UK and Romania, respectively; another developer who just turned 18 in August this year has been identified but has not been arrested due to some crimes occurring during their minor years.This operation, codenamed Operation KillSwitch, was led by the Hamburg State Criminal Police and the city's prosecution office, focusing on approximately 1,000 suspected attacks worldwide, with about 500 confirmed as successful intrusions.Law enforcement searched eight locations in Spain, Greece, Romania, and the UK, seized five central servers, and redirected related domain names to seizure announcement pages, while also confiscating at least 110 TB of stolen data.KillSec has been active since around 2024, exploiting software vulnerabilities and poorly secured cloud storage entry points to infiltrate corporate systems, copying internal data and naming victim organizations on dark web leak sites, threatening to publicly release documents to demand cryptocurrency ransoms, and if the target refuses to pay, they release the data for free.The Swiss Federal Police noted that the group also employed double extortion tactics, first encrypting servers and then applying pressure. U.S. prosecutors' charges indicate that a Dutch national residing in the UK, Fouad Eltibrizi (nicknamed Archduke), was indicted by a federal grand jury in Puerto Rico on September 16, subsequently arrested, and awaiting extradition, facing up to 10 years in prison. The European Cybercrime Centre, under the European Union Agency for Law Enforcement Cooperation, is assisting in tracing cryptocurrency funds and conducting digital forensics.

first_img Core Lightning warns that old version nodes are under attack and urges operators to upgrade immediately

The Core Lightning team, which develops the open-source Bitcoin Lightning Network node software, has issued an urgent alert stating that reports indicate attackers are targeting nodes that have not installed patches, urging operators still running old versions to upgrade immediately. The team stated: "Emergency security update: If you are using version 26.06.7 or earlier, please upgrade to the latest release as soon as possible."Prior to this, Core Lightning began investigating a potential issue that could affect its experimental features and, in turn, impact user funds on September 16, and approximately six days later, version 26.06.8 was released. This update not only fixed several defects but also provided patches for security vulnerabilities reported responsibly by multiple parties, thanking the Bitcoin Red Team and 12 other individuals and organizations in the release notes, while also acknowledging anonymous reporters.According to the changelog, this round of fixes covers a bug that could cause sender nodes to crash, requests that could exhaust REST interface memory, and a vulnerability that could result in user funds facing confiscation losses when closing payment channels. To provide operators with ample upgrade windows and prevent attackers from taking advantage of reverse engineering and exploitation, this version intentionally obscured some testing content. Additionally, in August of this year, the project initiated a collaborative fixing process after reviewing a large number of AI-generated general vulnerability disclosure reports, and two days later released version 26.06.7 to close confirmed vulnerabilities.
