Lumino Ceremony: Building the Privacy Protection Infrastructure

Published

5 years ago

on

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.

By

Guangzhou Lepu Machinery Co., Ltd. highlights its mechanical seal replacement solutions for John Crane, Grundfos, and other pump applications, supporting industrial maintenance requirements with replacement components and application-focused product options.

China, 16th Oct 2026 – Guangzhou Lepu Machinery Co., Ltd., operating under the Lepu Seal name, is highlighting its range of mechanical seal replacement solutions for John Crane, Grundfos, and other pump applications. The company serves industrial equipment users seeking replacement sealing components for pump maintenance, equipment servicing, and ongoing operational requirements.

Mechanical seals are essential components in many pumping systems, helping control fluid leakage where rotating shafts pass through equipment housings. Their condition can affect equipment reliability, maintenance schedules, and the handling of liquids in industrial processes. Selecting a suitable replacement requires attention to the pump model, operating conditions, fluid characteristics, and installation requirements.

Lepu Seal provides mechanical seal products intended for a range of industrial applications, including replacement options associated with established pump and sealing equipment brands. Its product offerings include cartridge mechanical seals and other sealing solutions designed for different equipment configurations.

Replacement Options for John Crane and Grundfos Applications

Industrial facilities frequently need replacement components when mechanical seals experience wear, leakage, or damage during operation. Compatibility is an important consideration because sealing requirements can vary according to equipment design, shaft dimensions, pressure, temperature, and the characteristics of the pumped medium.

Lepu Seal offers replacement solutions for applications associated with John Crane and Grundfos equipment. These options are intended to help maintenance teams and equipment purchasers identify components that correspond to their specific pump requirements.

Before selecting a replacement, buyers typically need to confirm the original seal reference, relevant dimensions, operating parameters, and installation configuration. Providing accurate equipment information can help suppliers assess compatibility and identify an appropriate product option.

The availability of replacement components can also support maintenance planning by giving industrial operators additional sourcing options when servicing existing equipment. Final suitability depends on the specific pump model, process conditions, and technical specifications of the replacement seal.

Cartridge Mechanical Seals and Industrial Pump Components

Cartridge mechanical seals are commonly used in industrial pumping applications because their assembled design can simplify certain installation and maintenance procedures compared with component-by-component seal arrangements. Depending on the equipment and application, cartridge designs may help reduce installation complexity and support consistent seal positioning.

Lepu Seal lists cartridge mechanical seals among its product offerings, including the LP 891 cartridge mechanical seal for paper-making equipment. The company also lists dry gas seal products and components associated with various pump configurations.

Its product listings extend to equipment associated with progressive cavity pumps, screw pumps, and other industrial pumping systems. Examples include products referencing SEEPEX, NETZSCH, VIKING PUMP, and BORNEMANN equipment.

These listings indicate the range of pump-related components presented in the company’s catalog. Specific availability, compatibility, materials, and performance characteristics should be confirmed directly with the supplier for each application.

Supporting Industrial Maintenance and Equipment Sourcing

Replacement mechanical seals play an important role in planned maintenance and equipment servicing across industries that rely on fluid-handling systems. Maintenance teams must consider factors such as leakage control, equipment specifications, installation conditions, and the properties of the fluid being handled when evaluating replacement components.

For purchasing teams, access to product information and direct communication with suppliers can help clarify technical requirements before an order is placed. Confirming the equipment model and original component details is particularly important when sourcing alternatives for existing pump installations.

Lepu Seal provides product information through its website, where prospective customers can review available categories and submit inquiries about particular components. The company can be contacted to discuss replacement requirements for John Crane, Grundfos, and other pump applications.

The guide shows creators how footage from Kling 4.0, Kuaishou’s newest video foundation model, becomes publish-ready social video with NemoVideo’s AI editing agent.

SAN JOSE, Calif., October 15, 2026 — NemoVideo , the Pro AI video editing agent for creators and marketers, today published a Kling 4.0 workflow guide as Kuaishou’s Kling AI rolls out Kling 4.0, its newest video foundation model. The guide explains how upgrades at the model layer carry through to creators’ finished videos, and how to turn Kling 4.0 clips into publish-ready content in NemoVideo.

NemoVideo Publishes Kling 4.0 Workflow Guide for Turning 30-Second AI Clips Into Finished Videos

Kling 4.0 extends single-pass generation to up to 30 seconds, double the 15-second ceiling of Kling 3.0. The model also supports up to 10 keyframes, up to 15 combined references across images, video clips and subjects, prompts of up to 8,000 tokens and output up to 4K.

How Kling 4.0 Upgrades Carry Through to the Final Video

Foundation models such as Kling 4.0 generate the raw footage. Application-layer tools such as NemoVideo turn that footage into videos creators can publish, and each model upgrade gives that layer better material to work with.

A 30-second generation gives creators more footage to cut from, so a single take can become several short edits with different openings. Keyframe and multi-reference control helps keep characters and products consistent across clips, making separate generations easier to cut into one sequence. 4K output leaves more room to reframe footage for vertical platforms such as TikTok, Instagram Reels and YouTube Shorts.

A longer, sharper clip is still raw footage. NemoVideo is built for the next step. It works with footage from Kling 4.0 or any other AI video model, including Veo and Seedance, and carries it to a finished video through a chat-based editing agent:

  • Turn a batch of generated takes into a rough cut with SmartPick, which removes weak clips and keeps the highlights
  • Plan the opening seconds with Inspiration Center, which analyzes trending videos and suggests hooks and scripts
  • Add trending caption styles in one click with Smart Caption, and voiceover and background music with SmartAudio
  • Ask Nemo Agent in plain language to reorder shots, tighten pacing or change the aspect ratio, then export a version for each platform

“Foundation models like Kling 4.0 keep raising what creators can generate,” said Jin Lee, Founder at NemoVideo. “Our job at the application layer is to make sure each of those upgrades shows up in the final cut, with the right opening, the right pace, captions and a version for every platform. The model decides what you can generate. The workflow decides what you can ship.”

Availability

The Kling 4.0 workflow guide is available now at https://www.nemovideo.com/model, alongside NemoVideo’s guides to other AI video models. Creators can start editing for free at nemovideo.com.

Feliciano Serrano Warns Kidney Disease Often Goes Unnoticed Until It Is Advanced

Published

3 hours ago

on

October 16, 2026

By

  • Feliciano Serrano, M.D., says too many patients in Los Angeles learn they have kidney disease only after it has already done lasting damage, and he is speaking out on why that keeps happening.

A Disease That Rarely Announces Itself

California, USA, Oct 16, 2026, ZEX PR WIRE — Kidney disease does not usually come with a clear warning. Blood pressure creeps up. Energy drops. Swelling in the ankles gets written off as a long day on your feet. By the time a patient feels unmistakably sick, the kidneys may have already lost a large share of their function.

“Kidney disease moves quietly,” Serrano said. “Most of my patients did not feel anything was wrong until a lab test told them otherwise. That delay is the real danger, not the disease itself.”

Serrano is a physician based in Los Angeles who treats patients with kidney disease and with the vascular conditions that often come with it. He trained in nephrology and later completed a fellowship in interventional and endovascular procedures, giving him a view of both how kidney disease is diagnosed and how it is treated once it has progressed.

Why the Gap Matters More in Some Neighborhoods

Serrano has spent much of his career treating patients in the inner city neighborhoods where he was raised. He says the gap between a treatable early stage and an advanced one widens further for patients who face language barriers or limited access to regular checkups.

“A patient who cannot explain their symptoms clearly to a doctor, or who puts off a visit because of cost or time, loses the exact window when kidney disease is easiest to manage,” he said. “I speak Spanish with my patients because that conversation is often the difference between catching something early and catching it late.”

He points to routine bloodwork, specifically a basic metabolic panel and a urine test, as the tools that catch kidney disease long before a patient feels sick. Neither test is unusual or expensive. The problem, Serrano says, is that they are often skipped until something else prompts a visit to a doctor.

The Part That Gets Left Out of the Conversation

Serrano’s early research, conducted during a fellowship at the University of Vermont School of Medicine with NIH support, looked at why people with kidney disease do not live as long as people with normal kidney function. The work focused on platelet activity and thrombosis, a connection between the kidneys and the cardiovascular system that he says still does not get enough attention from patients themselves.

“People think of kidney disease as a kidney problem,” he said. “It is also a heart and blood vessel problem. That connection is part of why early detection matters so much. The longer kidney disease goes unmanaged, the more it affects the rest of the body.”

This is also why Serrano’s practice, the Serrano Kidney & Vascular Access Center, treats kidney care and vascular care together rather than as separate visits. Patients who need a procedure to open or repair a blood vessel are often the same patients whose kidney disease was caught late.

What Serrano Tells Patients to Do

Serrano’s advice to patients is direct: do not wait for symptoms. Ask for a kidney function test as part of a routine physical, especially with a family history of diabetes, high blood pressure, or kidney disease. If a test comes back abnormal, follow up with a specialist rather than letting it sit on a chart unaddressed.

“I tell people the same thing I would tell my own family,” he said. “A number on a lab report is easier to deal with than a hospital stay. Ask the question before the disease forces you to.”

He also encourages patients to bring a family member or trusted interpreter to appointments when language is a barrier, so that nothing about their health gets lost in translation.

About Feliciano Serrano

Feliciano A. Serrano, M.D. is the Medical Director of the Serrano Kidney & Vascular Access Center in Los Angeles, California. He is a Diplomate of the American Board of Internal Medicine and a member of the American Society of Diagnostic/Interventional Nephrology. Dr. Serrano completed his medical degree at the Keck School of Medicine at USC, a nephrology and hypertension fellowship at the University of Vermont School of Medicine, and a fellowship in interventional and endovascular procedures at the University of Arizona College of Medicine. He treats patients with kidney disease and vascular conditions across Los Angeles and is fluent in English and Spanish.
