Behind High Energy Consumption of Blockchain: PoS Consensus Mechanism To Be A Solution
The energy consumption of Blockchain
Recently, Elon Musk, the founder of Tesla, posted on Twitter saying that: Bitcoin can consume too much in mining and transaction process, such excessive fossil fuel consumption will result in negative impacts on the ecosystem. The Ethereum co-founder Vitalik Buterin also noticed the high power consumption problem in Blockchain technology. He presented that Ethereum would change its consensus mechanism from PoW to PoS to reduce the power consumption caused by the mining process in PoW-based technologies like the Bitcoin. From a global view, energy consumption issues are concerned by an increasing number of countries. To urge the efficient power usage, many countries and organizations have set up environmental protection plans, such as the UN’s SDG (Sustainable Development Goals) and the US carbon neutrality, etc.
In this context, the future development of a technology need to consider the sustainable development and environmental friendliness as one of the important metrics and goals. As an emerging technology for privacy protection, Blockchain presents excellent protection capabilities. However, such capabilities rely on the large-scale computing resources and result in a large amount of power consumption. Part of the reasons for such high power consumption are due to the PoW (Proof of Work) consensus mechanism which has high demands on the performance of the Blockchain nodes.
Besides energy consumption, other concerns of the consensus mechanism
The technology of the base layer of the Blockchain has the advantages like anonymous, Immutable, decentralized and so on. To achieve these advantages, Blockchain enhances the privacy and protect the transaction process by increasing the cost of network participation. The core concept of the early-stage PoW consensus mechanism is based on the workload cost. The credibility need to be proved by the cost of a lot of work. In this case, the machines that maintain the ledgers (also referred to as mining nodes) need to continually crack complex math puzzles to obtain Bitcoin as rewards. This computing process not only needs to rely on a large amount of computing resources, but also sacrifices part of the scalability on the Blockchain to ensure safety. When it comes to the boosting growing of transaction volume, this mechanism will not be able to meet high-speed and large-scale processing demands. Based on such limitations of PoW, PoS (Proof of stake) is gaining more and more attention to work as a consensus mechanism with low resource consumption and guaranteed decentralization, safety and scalability.
In a PoS-based Blockchain system, nodes do not have to consume much power to compete for accounting rights. The priority of accounting rights is measured by the amount of stake holdings. In this way, the nodes no longer consume a large amount of electricity to calculate the hash functions, thereby solving the high energy consumption issues in PoW mechanism. In spite of the improved efficiency in PoS, the safety of the mechanism is affected. Therefore, in order to ensure the reliable operation of PoS, the researchers need to develop reliable algorithms from the trade-off among the decentralization, safety and scalability.
Unique advantages of PlatON PoS
With the issues caused by the PoW mechanism has been widely criticized, more and more Blockchain technologies inclined to choose or transit to the PoS-based consensus mechanisms. This results in a boosting growing of the PoS-based Blockchain frameworks in recent years. As the world leader in computing privacy area, PlatON has rooted and researched in privacy computing technologies many years. PlatON’s research and practice in consensus mechanisms are also forward-looking. The PPoS (PlatON PoS) consensus mechanism uses off-chain identity, credit mechanisms and procedural arrangements to provide a scheme to select a number of verification nodes from many participating nodes as fair and randomly as possible. Hence, PPoS can effectively inhibit bribery, collusion, etc., and reduce the consensus cost and improve the system scalability by optimizing technical details. Meanwhile, ensuring the decentralization and scalability, PlatON further enhances the system safety by combining the experiences in computing privacy area. The Alaya network based on PlatON PoS has been operating stably and efficiently for a long time, successfully solving the problem of over-centralization of the system, reducing network communication complexity and message complexity, improving consensus efficiency and the entire Blockchain transaction processing performance. In this case, the safety and liveness of the technology are verified. PlatON has been able to improve its PoS mechanism through its attention to every detail, continuous attempts, active exploration of cutting-edge areas, and forward-looking plans in the future development. Next step, PlatON will continue actively promoting the efficient network operation with high-quality code, providing efficient, high-availability, distributed and sustainable infrastructure applicable for diverse industrial and commercial use cases, and supporting the exchange of data flows in the global world.

How HiBT Event Contracts Work From Entry to Settlement
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.

Press Release
DHARIN Launches Lab Grown Diamond and Gemstone Fine Jewelry Collection for Everyday Wear
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’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
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.
