Increasing risk of privacy leakage in the post-pandemic era,PlatON: Privacy Computing is the solution

Published

on

After the outbreak of COVID-19, the risk of privacy leakage is increasing      

At the beginning of 2020, the sudden outbreak of the COVID-19 pandemic brought a huge impact on everyone’s work and life. On the one hand, the working-from-home scenario has pushed the development of digital office. Many companies have had to transfer the materials and assets from offline to online within a short time. On the other hand, to meet the demands of the public health and pandemic control, personal health data is collected and processed digitally to be used in areas like pandemic prevention and control, health services, and tracing inquiries. For instance, travel health codes have been used in countries like China and Spain for COVID-tracing, and many countries around the world have provided the online services of test appointment and test results inquiries. The outbreak of the COVID-19 pandemic has inspired people to rethink the construction and development of infrastructures. The large scale of data transmission and exchange during the pandemic period requires the support from new technologies. In the global context, in order to adapt to the ever-increasing demand for data exchange and promote the digitalization process, many countries have prioritized and invested on cutting-edge technologies like 5G, Big Data, Artificial Intelligence, Cloud Computing, etc.

Considering the abnormal conditions of the pandemic, it can be understood and accepted to a certain extent if the data is used by relevant agencies and organizations. In spite of this, after the pandemic, when the life is back to normal, can the data privacy be properly protected in the daily data collection, storage and computing? Can the basic rights of users be properly protected? With the development of the new technologies, when a large amount of data is collected, transmitted, analyzed and processed from the end devices through Internet of Things (IoT) and 5G technologies, the risk of data breaching will increase accordingly. In this case, how to get effective protection on the data privacy?

Privacy computing paves the road

Fingerprint recognition, face recognition, voice recognition and other technologies collect user information to provide users with convenient and efficient services, while also putting these basic personal data information at risk of being leaked and abused. With the successive promulgation and implementation of the European Union’s GDPR and the California’s CCPA Act, it is necessary for relevant parties to reflect their attitudes and operations towards data resources. In this context, Privacy Computing technology has gradually caught researchers’ attention.

Privacy Computing refers to a type of information security technology based on modern cryptography, which is represented by technologies like Secure Multi-party Computing (MPC), Homomorphic Encryption, Zero-knowledge Proof, Differential Privacy, and Trusted Execution Environment (TEE), etc. Privacy Computing can realize the data computing and analysis while ensuring the security and privacy of the source data.

So far, three major technologies are available to achieve Privacy Computing: Cryptography, Trusted Execution Environment, and Federated Learning. Among them, the privacy protection scheme based on cryptography is a type of computing method that protects private information throughout the entire life cycle, and supports operations such as analysis and computing without the data itself leaking to a third party. Its core concept is to form a set of symbolic, formulaic and quantitative evaluation criteria for Privacy Computing theory when processing information flow. [1] Compared with the problems brought by the traditional end-to-end encryption methods on the key management and performance impact, Privacy Computing can fundamentally protect data from the entire life cycle. In large-scale public infrastructure, the introduction and deployment of Privacy Computing support systematic data privacy protection.

At present, in addition to the in-depth research on Privacy Computing in the academia, the realistic application scenarios and large-scale commercial solutions of Privacy Computing are also being actively explored by the industry. Take PlatON Network as an example. PlatON has been developing and researching the field of Privacy Computing since 2016. The AI network of Privacy Computing provided by PlatON is a solution for privacy contract implementation based on cryptographic algorithms such as Secure Multi-party Computing (MPC). In general, the Privacy Computing algorithm is released through the contract. The data provider and the computing nodes that require privacy protection need to cooperate to execute the MPC protocol, so that to realize the collaborative data computing. In this case, data privacy is protected at the same time when data is shared, allowing users to obtain the economic benefits of data reuse while maintaining data ownership.

After the era of the pandemic, Artificial Intelligence (AI) also has caught in privacy issues during the process of data reuse. The development of AI technology turns data as a special asset, and its scale can affect both the model accuracy and the reliability of the services, which in turn affects business costs and risks. From the perspective of improving the accuracy of the AI model, the more data collected, the better the model performs, but the collection of large amounts of data also brings higher risks of privacy exposure. If AI is planned be applied in large-scale commercial scenarios, privacy is a crucial issue that cannot be bypassed.

Privacy Computing technology is born to be suitable for solving the privacy flaws of AI technology. A large amount of data is computed in an encrypted way, which not only solves the privacy problem in the traditional AI model, but also ensures the efficient data management and utilization. Considering the user’s personal health IoT data involved in this pandemic as an example, PlatON’s “DataBank” product can effectively protect the core data and provide lifecycle data-management services. Working as a data asset value-trading platform, PlatON’s “DataBank” product can guarantee the privacy and security of personal health data during the verification and transmission process based on Privacy Computing technology. With the AI technology introduced in PlatON’s “DataBank” product, multi-source and multi-mode local joint verification can be efficiently achieved. The results got from Privacy Computing can provide accurate delivery services among organizations and agencies, which not only addresses the issue of mutual recognition between different regions, but also supports the sharing of data marketing channels among various agents. In this case, it can jointly improve the accuracy of health data verification, and help industries realize and establish public health economic data services under the rapid development of 5G, Cloud Computing and other technologies for digitization. As the pioneer in privacy protection area, PLATON has researched Privacy Computing technologies for many years. The Privacy Computing network infrastructure developed by PLATON can guarantee the secure and free data flow across every corner of the world.  All types of Applications, relying on the data exchange and data computing as the core capability, can enjoy the convenience brought by global data collaboration and computing power sharing on PlatON.

How HiBT Event Contracts Work From Entry to Settlement

Published

on

A closer look at the opening price, early sale estimates and what determines the outcome at expiry.

Canada, 11th Nov 2026, Grand Newswire –
 

The most useful part of HiBT’s Event Contracts appears after the order is placed. On eligible positions, the app lets the holder see an estimate for selling before expiry. That can be useful when a Bitcoin move starts to reverse with time still left on the contract. The limitation is easy to miss: the estimate tells the holder what an early exit might return at that moment, and it may be less than the amount they put in.

The easiest way to misread the position screen is to treat its two USDT amounts as interchangeable. The potential payout describes what the contract may pay if the selected outcome is correct at expiry. The early sale estimate describes what closing the position could return before expiry. A trader can be right about the direction so far and still face a choice between accepting the amount currently available and waiting for a settlement that has yet to be determined.

The order screen is easy to read

A HiBT Event Contract takes a view on whether a selected price index will finish above or below its opening level at a specified expiry. The contract guide describes the two directions as Call and Put. A Call expresses a view that the index will finish higher; a Put expresses a view that it will finish lower. The order screen shows the duration, the amount committed and the potential payout.

The opening level is the number against which the expiry price is judged. It matters more to the result than the day’s opening price or any other price a trader happens to be following. Someone can correctly say that Bitcoin is up on the day and still have a losing Call if the index finishes below the opening level of that particular contract.

The opening price takes a closer look

HiBT’s execution notice says the exchange introduced a one-second delay between submission and execution on April 13, 2026. Under the published rule, the index at execution determines the opening price. The price visible when the user taps to submit is a reference figure and can differ from the price ultimately recorded on the order.

During a fast price move, even that short interval can change the reference level the contract must finish above or below. The recorded opening price is the figure that matters at settlement.

Early selling is the useful difference

The exchange’s more recent trading guide describes early selling as an available exit route. In the app, the option is labeled Sell Event Position. When it is available on an open contract, the confirmation screen shows estimated proceeds. That amount can change as the underlying price moves and the time left on the contract decreases.

A trader might look at the estimate after the market has moved in the expected direction. There is still a reason to look again if the market turns: the original view may no longer hold, and the amount available for an early sale may have changed as well. A changing estimate is useful precisely because it can be checked against the original amount. It also means a figure seen earlier should not be treated as the proceeds of a sale that has yet to happen.

The order amount is a useful comparison. If the sale proceeds exceed what the trader put in, a completed sale can realize a gain. If the proceeds are smaller, it can realize a loss. The price direction alone does not tell the trader which of those cases applies. What matters for that calculation is the amount actually received on the sale.

What the settlement record shows

For a contract held to expiry, the closing index is compared with the recorded opening level under the applicable rules. The market may have crossed that level several times during the contract. Those crossings explain why someone might have reconsidered the position, but they are not the settlement result. The opening price, expiry time and closing price are the figures that let the trader reconstruct the outcome afterward.

For a contract sold early, the relevant record is the completed sale. A subsequent move that would have favored the trader does not add to the proceeds. Nor does a later reversal reopen the position. Keeping those two records separate makes it possible to understand an outcome even when the closing price on a chart looks at odds with the amount received.

Recognition at the Global Onchain Awards

In October 2026, HiBT was named Best Global Event Contracts Exchange at the Global Onchain Awards, held during the Global Onchain Summit in Singapore. The organizer’s winners announcement reported more than 100 nominations across over 20 categories for the awards program as a whole. Those totals describe the program, rather than nominations or votes received by HiBT.

The published judging criteria covered market coverage, contract variety and the reliability of market resolution. The award was for the Event Contracts offering as a whole.

HiBT also offers an Event Contracts API for approved external platforms. The API serves a separate purpose from early selling: it lets approved partners connect their own systems to the product. For individual traders, the more immediate change is on the position screen, where an eligible contract can be closed before settlement.

The trade off on short contracts

The clearest part of the design is the choice at entry. A direction, a duration and a conditional payout give the order a defined shape. The early sale estimate adds a decision that makes sense for a short contract: if the trader has changed their mind, they can see what leaving would mean in USDT. That is more useful than seeing a countdown alone.

The harder part is keeping track of which number belongs to which moment. The index when the order executes can differ from the one visible at submission. The early sale estimate can change while the contract is open. The potential payout stays conditional until the outcome is known. A glance at the underlying chart cannot substitute for the order record, and a favorable move cannot tell someone how much an exit would return.

Early selling gives the holder a way to act on a change of view. How useful it is depends on whether the option is available on the position and what the sale would return. For a contract with little time left, those details matter more than the direction of the last price move.

On mobile, that decision happens on the open position screen. The iPhone app for the HiBT platform is listed as Global HibtHub on the Apple App Store. HiBT’s Android app is available on Google Play.

DHARIN Launches Lab Grown Diamond and Gemstone Fine Jewelry Collection for Everyday Wear

Published

on

United States, 11th Nov 2026, Grand Newswire – Fine jewelry brand DHARIN today released its first collection. Designed for everyday wear, the collection centers on lab-grown diamonds and lab-created sapphire, emerald and ruby, and is now available through mydharin.com to customers in the United States and Europe.

DHARIN Launches Lab Grown Diamond and Gemstone Fine Jewelry Collection for Everyday Wear
DHARIN’s pieces sit between fashion jewelry and traditional fine jewelry. The brand holds that fine jewelry need not be reserved for engagements or formal occasions, and can instead become an everyday choice, much like a classic piece in a wardrobe. The collection follows fine jewelry standards in its materials and settings, while its design takes cues from the way fashion is worn: each piece can be worn alone or stacked.
This approach shapes the brand’s choice of materials. Lab-grown diamonds share the same crystal structure, refractive index and hardness as mined diamonds, and lab-created sapphires, emeralds and rubies share the same composition as their natural counterparts. The difference lies in origin: lab-grown stones require no mining, and their growth process is fully traceable.
DHARIN views lab-grown stones as part of a more considered approach to fine jewelry, in which value comes from design, craftsmanship and wear, not from rarity alone. The same budget can allow for a larger stone or a higher grade, bringing D color, high clarity diamonds into everyday jewelry. Design is also less constrained by the cost of rough material, leaving more room to explore cut, proportion and color. Lab-created colored gemstones offer consistent color, allowing pieces in the same shade to sit together in harmony.
DHARIN regards jewelry as something to be worn rather than an investment, and encourages customers to build a collection over time, in keeping with their own style and pace of life.
The first collection is built around earrings and extends to rings and bracelets. The lab-grown diamond pieces center on three four-prong solitaire stud earrings, ranging from a 1 carat total weight round brilliant cut to a marquise cut and a 4 carat total weight oval cut, all in D color. The colored gemstone pieces include halo stud earrings, a halo ring and a tennis bracelet, each offered in sapphire, emerald and ruby. The halo pieces use a low setting suited to everyday wear. The collection is offered in metals including rhodium-plated sterling silver, 18K gold vermeil and 14K gold.
Each DHARIN product page lists the stone type, carat weight and metal, with color and clarity grades included for diamond pieces. Every lab-grown diamond of 0.50 carat and above is accompanied by an individual grading report issued by the International Gemological Institute (IGI). IGI is an independent gemological laboratory, and DHARIN is not affiliated with IGI. All colored gemstones in the collection are laboratory-created and identified as such on each product page, and brand certificates can be provided upon request.
The name DHARIN, pronounced DAR-in, is derived from a Sanskrit root associated with holding or sustaining, and is similar in sound to the English word “darling.”

About DHARIN
DHARIN is a fine jewelry brand specializing in lab-grown diamond and lab-created gemstone jewelry designed for everyday wear. The brand’s founder previously worked in retail for international luxury and fashion brands and holds a diploma in the Coloured Gem Professional programme from Gubelin Academy.

Rantizo (Nasdaq: RNTZ) Advances U.S. Production of Heavy-Lift Autonomous Drones After $258.8 Million Acquisition, Targets California’s $61.2 Billion Agricultural Market

Published

on

Houston, Texas, USA, November 11th, 2026, FinanceWire

California’s Central Valley to serve as U.S. launch market for the Houston-built Harvest 100, a heavy-lift agricultural drone with more than 70% U.S. or allied parts designed to cover 500 acres per day; Rantizo holds master spray agreements with Nutrien and Helena

Rantizo (Nasdaq: RNTZ) (“Rantizo” or the “Company”), the Houston-headquartered builder of American-made heavy-lift autonomous drones, today announced plans to expand its agricultural drone services into California’s Central Valley, which will serve as the U.S. launch market for the Harvest 100, the Company’s U.S.-built heavy-lift agricultural drone. The announcement comes one month after Rantizo completed its $258.8 million transaction and began trading on Nasdaq under the ticker RNTZ.

The Harvest 100: American-Made Heavy Lift

Rantizo designs and builds its aircraft in Houston, Texas. Its flagship, the Harvest 100, is a heavy-lift, autonomous agricultural drone built in America with more than 70% U.S. or allied parts and designed for FAA and NDAA compliance. Each Harvest 100 is designed to cover 500 acres per day, and the platform is built to be BVLOS-capable and swarming-ready, with modular payloads that carry it from spraying and seeding into forestry applications.

Rantizo is an approved drone application provider under master spray agreements with Nutrien and Helena, two of the largest agricultural retailers in the United States, positioning the Company to serve their grower networks. Rantizo is also seeing strong grower interest heading into the upcoming season, with drone sales agreements in place, multiple successful field trials, and FAA certifications and operational authorizations in more than 15 states. Growers and ag retailers can hire a Rantizo field team by the job or by the season, or buy, lease or finance the aircraft and fly it themselves, with pilot training available.

“America needs American drones, and we are building them in Texas today,” said Marianne McInerney, President of Rantizo. “The acquisition and the new ticker were the starting line. Behind them is an American shop floor, an American-made heavy-lift aircraft, and master spray agreements with two of the country’s largest ag retailers. California is where the Harvest 100 launches: the most valuable farm economy in the country, served by an American drone. As foreign aircraft are priced and regulated out of this market, Rantizo intends to be the American name growers and ag retailers call first.”

Harvest 100 U.S. Launch Market: California’s Central Valley

Rantizo plans to bring its agricultural drone services to California’s Central Valley, beginning with four adjacent counties: Fresno, Tulare, Kings and Kern. California is the nation’s leading agricultural state, with $61.2 billion in farm and ranch cash receipts in 2024, more than 400 commodities and more than three-quarters of the country’s fruits and nuts, according to the California Department of Food and Agriculture.

The corridor’s almonds, grapes, pistachios, citrus and vegetables are high-value specialty crops where precise, timely aerial application matters most, and where orchards, vineyards and wet or constrained ground can limit conventional equipment. Concentrating on four neighboring counties allows Rantizo to serve the region with mobile two-person crews and shared equipment rather than separate fixed operations.

The entry is phased and tied to contracted demand. Rantizo intends to work with experienced California license holders and its master spray agreement relationships with agricultural retailers to establish licensing, county registrations and channel partners, beginning operations with two drone pilot crews and scaling to as many as four crews across the corridor during the upcoming season as contracted acreage grows. The service business is also built as a direct sales channel for the Harvest 100: paid applications and field demonstrations introduce growers to the aircraft and build a pipeline for purchases, leases, pilot training and long-term service programs.

Federal Policy Is Shifting the Market to American-Built Drones

Federal policy has moved decisively toward domestic aircraft over the past 18 months. Executive Order 14307, “Unleashing American Drone Dominance,” directed federal agencies in June 2025 to prioritize U.S.-made drones. In December 2025, the Federal Communications Commission added foreign-made drones and critical drone components to its Covered List, barring new foreign models from equipment authorization unless exempted. And since September 3, 2026, imported unmanned aircraft with a maximum take-off weight above 25 kilograms face Section 232 tariffs of up to 100% under Presidential Proclamation 11055.

The market those rules protect is growing fast. The Federal Aviation Administration forecasts that the active U.S. fleet of large drones, those over 55 pounds, will grow from 8,295 aircraft in 2025 to 55,509 by 2030. The Harvest 100 is built for exactly that weight class.

Built on the $258.8 Million Transaction

Rantizo’s public listing was established in October 2026, when the Company completed its approximately $258.8 million acquisition of the drone assets of Houston-based Rantizo, Inc. and adopted the Rantizo name. Rantizo, Inc. received 51,966,591 newly issued Class A ordinary shares and held approximately 87% of the Company’s Class A shares following the closing, and those shares are subject to a six-month lock-up. The Company’s shares have traded on the Nasdaq Capital Market as RNTZ since October 13, 2026.

The Rantizo name has been field-proven since 2018, when it was founded in Iowa City as a pioneer of agricultural drone spraying. The Company is led by President Marianne McInerney, a former U.S. Department of Transportation official.

Rantizo expects to provide further updates on its California launch, commercial orders, production and deliveries as they are finalized.

Global Communications and Partnerships

Phoenix MGMT & Consulting has transitioned with the Company from SKK Holdings to Rantizo and continues to support its overall growth and global expansion, leading global communications, public relations and global partnership development. Phoenix’s work includes introducing Rantizo to prospective supply, manufacturing and technology partners across the drone, defense and advanced-materials sectors.

About Rantizo

Rantizo (Nasdaq: RNTZ), headquartered in Houston, Texas, designs and builds heavy-lift autonomous drones in the United States for precision agriculture, forestry and wildfire response, infrastructure inspection and specialized government applications. Its platform includes the U.S.-built Harvest 100 agricultural drone, the Titan firefighting and forestry drone and a long-range fixed-wing surveillance prototype, supported by field services and by purchase, lease and financing options.
