• Tether introduces QVAC Health, a health platform that pulls together fitness, sleep and nutrition data in a local, encrypted dashboard with on-device AI.
• The app is part of the QVAC initiative and is intended to serve as a “neutral ground” for wellness data – without the cloud, with AI models that come to the device via peer-to-peer.

Tether is entering the healthcare market. It wasn’t quiet, but it came surprisingly quickly. On Wednesday, the company QVAC Health unlockeda health and wellness platform that is intended to dump the usual data salad from Oura Ring, Apple Health, Google Health & Co. into a single timeline – without anything going to a Big Tech server. Instead, the evaluation runs directly on the smartphone or laptop, including AI models.

QVAC Health: Wellness timeline instead of data silos

Core idea: The app pulls data from various wearables and tracking apps into an encrypted, offline-capable dashboard. Steps, heart rate, sleep, training, nutrition logs, even medication reminders should end up next to each other – in such a way that the user can actually read them, not just in ten different tile views.

The interaction does not take place via menu deserts, but rather via voice and text. Users type or say things like “feeling tired after lunch” or “bench press 5×5 at 80 kilos”, the on-device AI classifies this into the personal chronicle, linking it to heart rate, sleep quality, stress. Honestly, this sounds more like a coach than a classic app.

There is also a feature that many people might initially frown upon: computer vision for food. Take a photo of the plate and the local AI will estimate calories and macros without uploading the image anywhere. I had to look twice because this exact function is almost always tied to some cloud.

What’s also exciting is what isn’t there yet, but has already been roughly outlined: QVAC Health will in future be able to talk to selected wearables directly via Bluetooth Low Energy and read in raw data – i.e. bypassing manufacturer APIs and their cloud. The AI ​​models run in the background and are distributed peer-to-peer; Updates come like a torrent, not a central download. In short: less platform, more infrastructure layer on your own device.

Paolo Ardoino has been talking internally for a long time about a “neutral ground for wellness data”. Now this formulation suddenly appears as a product: a layer that sits between the user and the ecosystems of Apple, Samsung, Google or Garmin – with the clear message that the user is the control point, not the cloud juggernaut.

Attack on Big Tech clouds – and component of the QVAC strategy

QVAC Health didn’t fall out of nowhere. Tether had already announced QVAC as a platform in May – a construction kit for AI agents that should run directly on end devices, without API keys, without dependence on data centers. In this roadmap, QVAC/Translate and QVAC/Health have already been mentioned as the first use cases, with a focus on privacy and self-sovereignty. Now the health part of it has just become real.

The health release also depends on a significantly larger bet on “Local AI”. Tether has poured billions into AI infrastructure, computing power and hardtech projects in recent months, including humanoid robotics and brain-computer interfaces. In this context, QVAC Health is more the visible tip of a stack that ranges from on-device LLMs (QVAC-fabric) to decentralized model download.

It’s a strange moment for the crypto market: the largest stablecoin issuer is suddenly building a health app that competes more with Oura, Garmin and Apple Health than with the next DeFi wallet. At the same time, Tether continues the familiar narrative – getting out of dependence on central gatekeepers, this time not for payments, but for biometric data.

Many detailed questions remain open. How deep direct device access will really go, which wearables will be connected first, what regulators will say if a stablecoin heavyweight gets into sensitive health data – none of this has yet been spelled out clearly.

But the framework is set: QVAC Health tries to keep the data salad from fitness, sleep, nutrition and medication on the device – and noticeably block Big Tech from accessing exactly this data. We won’t see on day one whether users will adopt this in large numbers.

• Bitget announced a major update to GetAgent, its AI-powered trading assistant.
• The update includes a more flexible response engine, an optimized interface and a significant increase in member quotas.

GetAgent, launched earlier this year, has become an important part of Bitget’s trading experience, helping tens of thousands of users simplify their analysis and executions.

The heart of this upgrade is the improved response system. GetAgent now intelligently detects what a user is asking – whether they want a quick overview or a comprehensive analysis – and automatically adapts their answer. For quick queries, the assistant provides a concise, actionable answer.

When deeper context is required, traders can, with a tap, activate research mode, which generates a complete multi-dimensional analysis that includes technical signals, risk considerations, on-chain data and market structures.

To complement the upgrade, Bitget has significantly increased the usage quotas for all GetAgent membership levels. All users now have more comprehensive access to daily queries, research results and analysis tools – even in the free basic version. Mid-tier members receive daily limits ten times higher than before, while Premium members now enjoy unlimited or near-unlimited access to GetAgent’s full information features.

Bitget has also redesigned the GetAgent interface for clarity and usability. The improved UI offers smoother navigation, a more intuitive chat layout and streamlined access to research reports, trade previews and position analysis.

In addition to the upgrade, Bitget recently released the KI-Trading-Camp introduced – specialized agents that execute live strategies with transparent performance. They provide users with an easy way to explore different trading styles and compare the real-time behavior of different models, further demonstrating the practical potential of GetAgent’s AI capabilities.

• Ripple’s XRP is now the third-largest position in the $1.25 billion Bitwise 10 Crypto Index ETF, the BITW.
• Institutional demand for XRP ETFs is increasing, with inflows approaching the billion-dollar mark.

Bitwise has reiterated its confidence in XRP as the token’s adoption among crypto exchange-traded funds in the US continues to grow. According to Bitwise, XRP is “a crypto asset with the potential to reshape how the world moves money.”

XRP becomes BITW’s third largest holding

XRP is now in the top 3 in the Bitwise 10 Crypto Index ETF (NYSE: BITW). Bitwise confirmed that XRP has become the third largest position in the $1.25 billion BITW fund, accounting for 5.17% of total TVL. XRP follows Bitcoin with 74.3% and Ethereum with 15.54% share of the fund.

Solana follows with 3.06%, while other assets such as Cardano, Chainlink, Litecoin, Sui, Avalanche and Polkadot hold less than 1% each.

In addition to BITW’s performance, Bitwise’s XRP ETF also achieved excellent performance. Among newly launched crypto funds, the ETF has been one of the most consistent performers since its debut on November 20th. Bitwise’s fund has raised a total of $192.76 million in inflows and now holds approximately 100 million XRP, with assets approaching $200 million.

On the other hand, institutional demand for the asset has increased significantly. Inflows into the XRP ETFs are slowly approaching the billion dollar mark, with the billion will be reached after another $60 million. XRP ETFs are on track to become the fastest product to reach this mark since the Ethereum ETF launched in 2024.

To demonstrate the growth, data from Sosovalue on December 4 showed that spot XRP exchange-traded funds recorded a daily net inflow of $12.84 million, while Bitcoin and Ethereum ETFs recorded net outflows.

At the time of writing, XRP is trading after a marginally negative move for 2,06 $ traded. Despite a series of positive developments, the token has come under pressure in the last few days and has seen almost 6 % lost.

Meanwhile, Europe’s MiCA rules have created new avenues for compliant XRP trading, allowing licensed operators in countries such as Germany, France and Switzerland to process institutional volume via RippleNet. As already mentioned in our report,Germany leads the EU with 36% of MiCAR licenses and has developed into a crypto hub through its early regulatory readiness. Ripple executives have predicted a 35% increase in cross-border settlement volumes in Europe compared to last year. In particular, transaction volume on RippleNet increased by 7.4% quarter-on-quarter.

• Chainlink and Mastercard connect fiat systems with DeFi, giving billions of customers direct access to cryptocurrencies.
• Swapper Direct Deposits replaces old, fragmented systems with a single onchain channel.

Chainlink has aligned with Mastercard and Swapper Finance to create a new path for over 3.5 billion Mastercard cardholders to free upto directly access decentralized finance. The new system, called Swapper Direct Deposits, connects the global fiat payment system with onchain protocols by leveraging Chainlink’s secure infrastructure.

The process runs through the Chainlink Runtime Environment CRE, which carries out the entire transaction flow on the chain, including identity verification, regulatory screening, fiat to cryptocurrency conversion, and settlement. Mastercard provides the payment basis via its global network and Swapper Finance handles the direct interaction with the customer.

— Chainlink (@chainlink) December 9, 2025

This partnership eliminates several steps typically required to get started with DeFi, such as separate KYC processes, payment setup and liquidity management, which were previously handled through separate systems.

Mastercard + Chainlink = DeFi access

With the launch of Swapper Direct Deposits, users can now use traditional cash cards, Web3 wallets or crypto transfers to deposit directly into DeFi protocols. This integration replaces the fragmented onboarding processes with a unified structure that works in a single onchain environment.

Roman Tirone, senior manager at Chainlink Labs, explained:

“We are excited to enable Direct Deposits with Mastercard and Swapper Finance to enable real-world payments directly in secure onchain workflows using the Chainlink Runtime Environment.”

The goal is to make the process routine for as many customers as possible, leveraging institutional-grade security while reducing abandonment rates caused by older, less optimized systems. Technical integration has already begun, with several Web3 platforms embedding direct deposits into their systems, suggesting growing demand for smoother DeFi access coupled with familiar payment tools.

Arthur, CTO of Swapper Finance, explains:

“This is the level of onboarding we always believed the industry needed… Our goal has always been to remove the barriers that keep billions of people from accessing DeFi, and now that future is becoming a reality.”

Currently Chainlink (LINK) is at 14,16 $ traded, after an increase of 3,51 % in the last 24 hours. Revenue also increased by 41.75% and reached $755.35 million.

• A policy paper from INATBA, which was co-authored by an expert from the IOTA Foundation, criticizes the outdated financial rules on Web3.
• The report argues for a shift to a proportionate, risk-based framework that classifies digital tokens based on their actual function.

Die International Association for Trusted Blockchain Applications (INATBA) hat ein Policy paper publishedin which she advocates a change in the regulation of Web3 and Distributed Ledger Technology (DLT). The interest group opposes regulators’ attempts to apply outdated and therefore inappropriate financial regulations to blockchain technology.

One of the paper’s lead authors is Giannis Rousopoulos of the IOTA Foundation, who along with four other experts lament and question the “regulatory mix” that characterizes today’s digital economy.

Titled “A Critique of Regulatory Mixture in the Digital Economy,” it claims that regulators do not understand how decentralized systems actually work and therefore fail by imposing traditional financial rules on them. Experts from the IOTA Foundation and INATBA contributed to the analysis and warn that applying traditional financial models to these systems “causes friction and undermines the fundamental principles of decentralization.”

The report fundamentally rejects the “same activity – same regulation” approach. By treating every digital asset like a security or requiring decentralized autonomous protocols (DAOs) to operate like centralized financial institutions, regulators risk crippling innovation and pushing development offshore.

The authors advise:

“Regulation should introduce a functional classification test to clearly separate tokens that represent financial instruments from those that represent ownership, claims, access rights or governance rights.”

This will prevent double regulation, which poses the risk of double taxation. Furthermore, the technical limitations of directly applying rules such as the right to erasure – from the GDPR – to immutable public ledgers should be recognized.

In addition, INATBA policy advocates a risk-based, tiered regulatory approach. This structure would scale compliance obligations based on an actor’s size, structure, and actual extent of control over a network.

“The path to true transparency requires frameworks that are technically sound, risk-appropriate and proportionate.”

IOTA is changing hands for at the time of going to press 0,1059 $after the price in the last 24 hours 3,03 % has increased. The token’s market capitalization is $443.25 million.

• Google AI models will be integrated into Fetch.ai Agentverse in the future.
• The FET price responded with an increase of almost seven percent.

Fetch.ai, the company behind the FET token, has partnered with Google Cloud. The two companies want to expand Fetch.ai’s open Agentverse platform.

In one Blog post Fetch.ai explained that the partnership will make AI agents more accessible and manageable for developers worldwide. Fetch.ai’s Agentverse has the previously poorly understood ability to deliver “turnkey” autonomous AI agents that are comparatively easy to interact with.

Described as the future of AI, Fetch.ai’s open platform is different from “traditional AI” that relies on single models. According to Fetch.ai, multi-agent systems cooperate with each other, which means they can also handle complex tasks.

Fetch.ai explained that Google’s advanced AI models are agent-ready: Gemini 3 for logical reasoning, Nano Banana Pro for precise, context-rich visualizations based on real-time information, and Veo 3.1 for video generation. All of this can be integrated into Agentverse.

The partnership is expected to significantly improve Agentverse connectivity. As CNF reported, has Fetch.ai’s Innovation Lab Beginning July 2025 am „Google AI Build Day v4.0“–Event participated , which included a session to enable Google’s A2A protocol in the Fetch.ai Agentverse.

The protocol enables the combination of AI agents from both systems. This accelerates the time-to-market from prototypes to mature AI applications. Through verified identities, reliable messaging, and easy agent discovery, Agentverse makes building complex, decentralized AI much easier.

Additionally, the integration will also enable advanced payments in the form of AP2 flows. This allows agents to securely request and confirm funds. This enables transparent pricing, paywalls and secure exchange of value between agents.

Meanwhile, FET, with a current market cap of $586.35 million, has seen a price increase of 6,97 % on 0,2536 $ recorded. The AI ​​sector has grown 2% and now has a market cap of over $29.5 billion.

• Around 4.05 million BTC are currently held by companies, institutions and ETFs worldwide.
• According to a study by Presto Research, Bitcoin fell the most during the November crisis during the respective European trading hours.

New data has shown that approximately 4.05 million BTC are currently not in circulation but are held by investors. Based on the immutably limited total Bitcoin quantity of 21 Million tokens 19% of it is currently invested.

They are primarily found in corporate and institutional and government reserves, as well as in the form of ETFs and other forms of investment, including direct Bitcoin ownership.

It Data According to listed companies such as Strategy, Tesla and Block, they now hold over 1.06 million BTC, which represents 5% of the total.

The approval of the first Bitcoin ETF in the USA in early 2024 played a major role in all of this. The current ETF holdings of asset managers and other funds are 1.49 million BZC.

In addition, the number of Bitcoins held by private companies, exchanges, custodians, in DeFi and smart contracts is almost 1.45 million – another 36.4 percent.

Crypto analysts are rightly talking about a Bitcoin bull market. As more and more companies invest in Bitcoin for the long term, the freely available supply is shrinking. The result is a shortage and it will lead to a new increase in the BTC price.

On the other hand, recent analysis also suggests that over-leveraged companies may be forced to sell their Bitcoin reserves to pay dividends and cover other expenses. Such sales could create sudden waves of downward pressure that would unexpectedly push prices lower.

EU trade caused the high BTC selling pressure

One Study from Presto Research shows that the overall 20% price decline of Bitcoin and Ethereum in November took place primarily during European trading hours. In particular, the Bitcoin price had its worst monthly performance in seven years.

According to Presto Research, only Europe had large Bitcoin losses, while Asia and the US still saw small gains.

• The LUNC price has risen over 20% in the last few days as the community is now aware of the v3.6.1 upgrade. votes.
• The upgrade is intended to provide, among other things, greater security, smart contract capabilities and stability of the network.

LUNC is Terra Classic’s native token, and it has been surging over the last week 127,44 %. In the last 24 hours, the token has increased by more 22% increased, and now he is at 0.00006019 $ traded. This increase pushed Terra Classic’s market cap to $330 million, while revenue rose to $265 million.

Amid this surge, the Terra Luna Classic community is voting on the proposal to upgrade to v3.6.1. If the proposal is approved, the upgrade will occur on December 18th at block size 26,479,000.

Das Upgrade

According to that GitHub report The upgrade will resolve any compatibility issues with older smart contracts that do not work well with newer software versions. Additionally, the existing libraries and modules will be updated to their latest stable versions. This will help reduce the likelihood of vulnerabilities and performance issues. It will improve the functionality of the smart contracts and allow developers to build more complex interoperable applications on Terra Classic.

The proposal already has overwhelming support: 99.34% of votes were cast and there were only 0.66% against. Major validators including BiNodes, Garuda Universe and Hexxagon have already come out in support of the upgrade, reflecting the high level of community trust.

The release candidate was successfully tested on the Rebel-2 testnet on the 25th last month, confirming that it is ready for deployment on the mainnet. To protect against possible problems, a rollback option has been prepared that allows the chain to revert to version v3.6.0 in case block production fails.

In such a scenario, validators may need to restore the network to its previous state and install a patched version v3.6.1. In this case, all validators would need to update their clients in a timely manner to maintain consensus.

Incidentally, Terra founder Do Kwon is on trial in New York for his role in the $40 billion Terra crash in 2022. In May of this year, TerraUSD, the project’s dollar-pegged stablecoin, lost its dollar peg, setting off a chain reaction that sent Luna Classic and other tokens crashing.

As CNF reported, the crash has led to a high-profile trial, with a verdict set for December 11th. Kwon pleaded guilty in August after being arrested in Montenegro in 2023.

• Polygon’s Madhugiri hard fork is activated at 80084800.
• Fusaka EIPs improve network security, enable one-second consensus, and support sophisticated gaming and financial transactions.

Polygon is preparing for its Madhugiri hardfork, which is activated today. The upgrade introduces Ethereum’s Fusaka EIPs – EIP 7883, 7825 and 7823 – to increase the pace and strengthen the network for its growth.

Tomorrow, Polygon is upgrading to make future speed boosts easier to ship, and increasing network throughput by 33%.

The Madhugiri Hardfork makes certain throughput increases as easy as flipping a few switches. It also continues to improve network stability and adds support for… https://t.co/SFu3AhtjVM pic.twitter.com/vNoT65BKGV

— Polygon | POL (@0xPolygon) December 8, 2025

The hard fork brings a 33% increase in network throughput through improved consensus timing and optimized block structuring. The POL network can now adjust block times without the need for future upgrades. Validators and developers benefit from faster node synchronization, reducing operational stress during times of high demand.

In addition to optimizing throughput and synchronization, the hardfork also increases security. The Fusaka EIPs introduce strict gas restrictions and limit calculation operations to a maximum value. The changes are intended to mitigate vulnerabilities and align the Polygon execution environment with Ethereum standards.

Polygon accelerates consensus and block upgrades

Madhugiri also enforces PIP-75 and PIP-74, enabling one-second consensus intervals and canonical incorporation of StateSync data into block bodies. Polygon emphasizes that users do not need to take any action during the update. The network ensures a smooth transition to a faster and safer environment.

The new block structure and timing improvements allow Polygon to process transactions more smoothly. Faster consensus building and improved block creation increase performance under heavy usage. The upgrade ensures that gaming, DeFi and other heavily used applications run smoothly and the network can easily handle growing demand.

Technical monitoring shows the stability of the network before activation. Throughput and block production metrics suggest that the new rules can be implemented. Observers are waiting for the hardfork to validate Polygon’s ability to scale and verify that it meets security standards.

Germany has followed the trend towards regulated blockchain with a €100 million digital bond issued by NRW.BANK on the POL platform in accordance with the Electronic Securities Act (eWpG). The issuance process was managed by a BaFin-licensed registrar and monitored by Deutsche Bank, DZ BANK and Deka-Bank.

• A Zcash developer has presented a detailed framework for a dynamic fee system that is intended to bring more security.
• It stipulates that transaction costs are adjusted based on current comparative data and simulated congestion.

Shielded Labs, an independent Swiss organization that supports Zcash (ZEC), presented the “Zcash Dynamic Fees Lab” proposal. Looking at historical context, he notes that fees originally started at 10,000 zatoshi before dropping to 1,000. However, these low base fees made the network vulnerable to “sandblasting attacks,” where large numbers of transactions could bring down the chain. Shielded Labs states:

“In response, Zcash Dynamic Fees Lab introduces Action Abstraction, which combines transparent inputs and outputs, Sprout JoinSplits, Sapling Outputs and Orchard promotions into a single accounting unit.”

The aim is to create a market where customers pay fees based on recent transaction activity, with adjustments made based on network congestion. This approach relies on analyzing the fees that customers have recently been willing to pay and using it as comparative data.

This comparison-based pricing is common, for example in NFT collectibles and real estate.

This is how it works

The system calculates a baseline based on the last hour’s activity, typically around 50 blocks, and adds a buffer of 5 blocks to prevent tampering. To model an always-active network, synthetic transactions of average size are included. The initial minimum price can be very low as it is adjusted upwards over time.

The standard fee is then defined as the average fee per action from the observation period. To support the network sustainability mechanism, the minimum price should be divisible by five, so that around 60% of the transaction fees can flow back into the issue.

To simplify the system and reduce fee fluctuations, the average fee per action is rounded to the nearest power of ten, which also limits information loss and reduces the potential for transactions to be linked. Over time, the median fee will increase and customers will be able to prioritize their transactions by temporarily enabling a “fast track” with a 10x fee multiplier, while miners will be expected to process higher fee transactions first in their own economic interest.

The rollout will initially begin with a monitoring phase, followed by a strategy phase and a consensus phase to enforce on-chain fees, as well as threat modeling to protect against spam and potential privacy leaks.

Interest in Zcash has also grown among institutions. How CNF reportedGrayscale has filed with the SEC to convert its Zcash trust into an ETF and plans to list it on the NYSE Arca under the ticker “ZCSH” to provide investors with regulated exposure to Zcash.
