Lumino Ceremony: Building the Privacy Protection Infrastructure
PlatON, a privacy AI computing network which is committed to building a decentralized collaborative artificial intelligence network and global brain, is promoting the democratization of artificial intelligence and establishing a secure general artificial intelligence. The bottom layer of its decentralized privacy protection infrastructure is based on Zero-Knowledge Proof.
What is Zero-Knowledge Proof
Zero-Knowledge Proof is a cryptographic technology to realize privacy protection authentication. The prover needs to make the verifier believe that he knows or owns a message, without disclosing any information about message which is to be confirmed. For example, if the prover wants to prove that he knows the safe box password without revealing it, he can just show some items existing in the safe box that everyone knows.
This process is Zero-Knowledge Proof. The proof needs an initial credible setting (some items existing in the safe box that everyone knows), namely a series of public parameters to help the prover build Zero-Knowledge Proof.
Deficiency of Zero-Knowledge Proof
As a cryptographic technology with both privacy protection and authentication capability, zero-knowledge proof is widely used to realize transaction verification under hidden business details in blockchain. The zero-knowledge proof system applied in the blockchain field is mainly a cryptographic algorithm called “zk-SNARKs”. At present, the existing classic zk-SNARKs algorithms include GGPR13, PGHR13, Groth16, GM17, and new generation algorithms such as Sonic, Marlin, Plonk, which support updating public parameters. The current version of ZCash, a well-known private cryptographic currency, uses Groth16 algorithm.
From the above “safe box”, we can see that the premise for the correct operation of this kind of algorithm is existing a series of random trusted parameters. However, randomized parameters will not come out of thin air and there is no trusted third party in the blockchain. Parameters created by centralized third parties can be reconstructed in theory, and it is possible to forge proofs, which may destroy the underlying security in PlatON. Imagine that if a specific institution informed the verifier of the storage of the items in the safe box, the institution and the prover could collude and use this secret information to falsify the illusion that the prover knew the safe box password.
Therefore, it is an undoubtedly excellent idea to organize multiple participants to create these randomized parameters through Secure Multi-party Computation. In this process, single party can not reconstruct the parameters any more. Only when this activity is completed safely will the subsequent decentralized application be safe. In fact, ZCash has successfully created system parameters for Groth16 algorithm in November 2017 through its ceremony, Power of Tau.
Lumino, creating secure parameters
In order to prevent the parameters generated by the centralized mode from affecting the underlying security, PlatON started the Secure Multi-party Computation ceremony Lumino on June 21, 2021, last for 60 days. This ceremony is expected to create necessary secure parameters for the Zero-Knowledge Proof protocol.
During the Lumino ceremony, multiple participants carry out several rounds of calculation in the form of a relay, that is to say, the current participant need to use the calculation results of the previous participant as the input of this round, and the calculation output become the calculation input of the next participant as well. After a certain number of rounds, the output of the last participant is the final result of the whole ceremony, namely the system initialization parameters that Plonk thatalgorithm of PlatON will choose. Obviously, the more participants take part in the ceremony, the safer the parameters will be.
As a practical and efficient Zero-Knowledge Proof algorithm, Plonk is commonly used in PlatON projects and communities, which is characterized by a one-time initialization process, that is, running once can be used to deploy multiple applications. Providing necessary initialization parameters for Plonk algorithm through Lumino ceremony means that no one can master the secret information behind the parameters, which can be used to cheat players in the whole system. Lumino ceremony will lay a solid foundation for the security of PlatON.

Actbest E-Bikes: Strong, Green, Electric Bikes Designed For Daily Uses Act
United States, 6th Dec 2025, – Actbest was born from the idea that riding needs to feel convenient, enjoyable, and truly useful in the real world. At its core, Actbest is an online brand for e-bikes targeting commuters and enthusiasts looking to spend quality time in nature at the weekend. Actbest makes electric bikes that support riders looking for power, affordability, and environmental sustainability all in one vehicle. Whatever your current level of experience with electric bikes, the range at actbestbike.com will help you ride better, not just faster.
Entire Brand Developed around the Rider
Right from the start, Actbest has emphasized what commuters want most in an electric bike: enough power to overcome hills, enough range to ride to and from work or other daily destinations, and enough comfort to enjoy every ride. Most models offer peak motor power of up to 1200W and speeds of up to 28 mph, giving riders the freedom to ride through streets, roads, and trails without worrying about taking on challenging terrain. Ranging from 55-65 miles per battery charge, most bicycles offer ample range without the need to frequently recharge. On the website, there are distinct categories such as moped style e-bikes, fat tire e-bikes, commuter bikes, 3-wheel trikes, and folding e-bikes so that consumers can easily pick up the bike of their choice depending upon their lifestyle. It represents the fundamental purpose of Actbest—translating complex technology into something accessible.

From Apex to Triker: A Growing Product Story
The brand story of Actbest is arranged chronologically, a timeline of innovation. In 2020, the company launched the Apex Electric Mountain Bike-an early flagship meant to turn each ride into an adventure with off-road capability and robust build quality.
In 2021, the Core ST arrived, mixing urban style with accessibility. A low step-through frame with comfortable geometry made it ideal for riders of different ages and also for those with limited mobility. For 2024, the Core 2.0 upgrade gave that platform improved performance and more polished urban comfort, signaling Actbest’s long-term commitment to commuters.
The Summit full-suspension bike, launched in 2022, pushed deeper into off-road territory with a 1200 W motor, wide tires with 20″ × 3″ dimensions, and full suspension tuned for rough terrain. A year later, the Ranger fat-tire series expanded on that spirit of adventure and exploration, putting a powerful, adventure-ready platform underneath riders for forests, mountains, and unpaved routes.
By 2024, Actbest introduced the Striker, positioned as a rider’s “first performance beast,” capable of speeds up to 28 mph and ranges up to 65 miles-ideal for enthusiasts who want more power and distance without jumping into premium, four-figure boutique pricing. In 2025, the brand added the Triker, a three-wheel e-bike that emphasizes stability, cargo capacity, and confidence for riders who value balance and comfort above all.

A Growing Community of New E-Bike Riders
Beyond the bikes themselves, Actbest is steadily building a community around smart, sustainable riding. The brand’s blog features practical guides—from waterproofing tips to workout benefits of riding an e-bike—while its Facebook community encourages riders to share photos, ask questions, and trade real-world advice.
Actbest also collaborates with YouTube reviewers and e-bike content creators, helping new riders see honest, ride-tested impressions of its models. That ongoing conversation between brand, reviewers, and everyday riders supports the same goal: making electric mobility more accessible, more transparent, and more fun.

Annual Sale with Arspura: Major Savings and Next-Gen Kitchen Ventilation
United States, 6th Dec 2025, – Arspura, a new-generation kitchen ventilation brand, today announced its biggest Annual Sale to date, featuring discounts all range hoods and free standard installation.
This year’s Annual Sale Range Hood Sale marks an important moment for Arspura, a brand built on the belief that better air leads to a better life. Rather than treating range hoods as simple appliances, Arspura focuses on kitchen air quality as a daily health priority, engineering products that combine ultra-high airspeed, filter-free internal structures, and intelligent monitoring to tackle smoke, grease, and fine particles at the source.

At the heart of this vision is Arspura P1, the hero range hood for families who value strong, low-maintenance smoke capture. Alongside P1, Arspura is broadening its portfolio with IQV
models like P2 and C5, and a next-generation F1 flagship focused on ultra-high airspeed and modern kitchen design.
Annual Sale Focus: Arspura P1–Built for Serious Home Cooks and Cleaner Air
Leading this year’s sale campaign is Arspura P1 IQV Hood , the flagship range hood. Designed for home cooks who love high-heat cooking but want a calmer, cleaner kitchen, P1 embodies Arspura’s brand promise:
- IQV
leak-reduction design to help prevent fumes and grease from escaping. - High-speed smoke capture that keeps up with intense stir-frying and searing.
- Real-time air quality monitoring via built-in sensors, visualizing kitchen PM2.5 levels at a glance.
- Quieter performance than many conventional “high CFM” hoods, making conversations and family time around the kitchen more comfortable.
With $600 OFF plus free installation (normally $199–$299), the P1 brings premium, health-focused ventilation within reach for more households upgrading their kitchens this sale.

Introducing the Next Generation: F1, P2, and C5
Arspura is rolling out three new models designed for different kitchen layouts and ventilation needs — with a special spotlight on the flagship F1.
Arspura F1: Next-Gen High-Speed Ventilation for Modern Kitchens
Arspura’s 30″ high-airspeed flagship for contemporary kitchens, F1 combines powerful smoke capture with low-maintenance design:
- Ultra-fast airflow: Airspeed up to 16 m/s captures smoke at the source before it can rise and spread.
- BLDC motor with filter-free airflow path: A high-performance BLDC motor and filter-free internal design keep suction strong without frequent filter changes or deep disassembly cleaning.
- Seamless kitchen fit: Sized to align with most standard cabinets and cooktop layouts, making it easy to upgrade existing kitchens without major structural changes.
- Streamlined design with smart control: A side-baffle-free silhouette creates a lighter visual profile and elevates the overall kitchen aesthetic, while gesture control and smart connectivity enable intuitive, touch-free operation.
For design-conscious households, it adds up to a centerpiece that keeps the air clear while blending seamlessly into contemporary cabinetry and routines.
Arspura P2: Strong Ventilation with Deep Purification
The Arspura P2 is built for homeowners who prefer a top-suction range hood with strong coverage over multiple burners. Combining Arspura’s IQV
airflow with a wide capture area, P2 creates a powerful “air curtain” that surrounds the plume of smoke and channels it upward efficiently.
In select configurations, P2 also integrates advanced purification features, helping to reduce lingering odors and fine particles after cooking. It is ideal for families who cook daily and want both strong smoke extraction and a fresher overall kitchen environment.
Arspura C5: Intelligent Monitoring for Cleaner Kitchen Air
The Arspura C5 goes beyond a traditional range hood by adding intelligent air quality monitoring into the heart of the product. With built-in sensors that can track pollutants such as PM2.5、CO and gas levels, C5 gives households a real-time view of their kitchen air and provides extra peace of mind during intense cooking sessions.
For health-conscious families, this transforms invisible risks into clear signals, helping them adjust ventilation and cooking routines with greater confidence.

Patented IQV
Technology: Capturing Smoke at Its Source
At the core of Arspura is the brand’s proprietary IQV
(Inclined Quad-Vortex) technology. Unlike conventional range hoods that rely mainly on large CFM numbers, IQV
focuses on high airspeed and smart airflow design to capture smoke before it can escape.
The system coordinates three key airflow patterns inside the hood:
- An inclined jet stream that immediately draws smoke and steam inward from the pan.
- A quad-vortex chamber that spins air rapidly, separating grease and particles from the airstream.
- A protective air curtain at the front edge that helps prevent smoke from drifting toward the cook’s face or into the room.
By combining these airflow modes with high-speed motors and a thoughtful internal layout, Arspura hoods are engineered to keep PM2.5 levels lower, reduce cooking odors faster, and minimize grease buildup inside the machine.
Sales Details
For a limited time during the Arspura Annual Sale range hood promotion period (ending December 7, 2025), customers can enjoy:
- $600 OFF
- Free Installation (Kitchen remodeling is NOT included)
- Free Gifts (Water filter pot , juice pitcher, slice toaster, and waffle maker)
With deep savings on both the product and installation, this Annual Sale is an ideal opportunity for homeowners to replace aging, noisy, or underperforming hoods with a high-speed Arspura model engineered for cleaner air and a more comfortable cooking experience.
About Arspura
Arspura is a kitchen ventilation brand dedicated to the vision of “Better Air, Pure Life.” Through aerodynamically inspired IQV
airflow design, smart sensing, and human-centered product thinking, Arspura aims to redefine how families experience air in the kitchen—transforming smoky, noisy spaces into cleaner, calmer everyday living environments.
