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.

Marcos Neves Rodrigues sets a one-year standard for storm-season readiness in Florida hotels
Florida, USA, September 19th, 2026, ZEX PR WIRE, Marcos Neves Rodrigues, a Florida hotel manager, is committing his property’s team to a one-year cycle of hurricane-season readiness reviews, run every year at the same fixed points on the calendar.
A commitment tied to the calendar, not the weather
Marcos Neves Rodrigues has spent his career managing hotel operations in Florida, where hurricane season is not a hypothetical. He is now formalizing a practice he has used informally for years: a fixed, year-round readiness cycle for his property, rather than a scramble that starts when a storm enters the forecast.
“Waiting for a named storm to start planning is already too late,” Rodrigues said. “The teams that handle a hurricane well are the ones that already knew, months before, exactly who does what.”
The commitment breaks the year into four checkpoints, each with a specific task attached, rather than a single “hurricane plan” filed away and forgotten.
The four checkpoints
Early spring: supply and vendor review. Rodrigues commits his team to confirming backup suppliers for water, generator fuel, and non-perishable food before the season opens. He said this is the point most properties skip because nothing feels urgent yet.
Early summer: staff role assignments. Every department head gets a written role for before, during, and after a storm. Front office, housekeeping, and maintenance each get a specific checklist, not a general instruction to “help out.”
Peak season: communication drills. With guests on property during active months, Rodrigues has his team run short internal drills on how information moves: from management to staff, and from staff to guests. He said the drill matters more than the plan itself, because plans fail quietly while drills expose gaps out loud.
After season close: a debrief. Once hurricane season ends, the team reviews what actually happened that year, storm or no storm, and updates the plan for the next cycle. Rodrigues said this step is the one that keeps the whole cycle from going stale.
Why he is naming it publicly
Rodrigues said he decided to put the practice into a named, public commitment rather than keep it as an internal habit, because hospitality teams often trade notes across properties informally.
“If another manager reads this and steals the debrief step, that’s a win,” he said. “None of this is proprietary. It’s just structure.”
He said the biggest failure point he has seen in hotel storm response is not lack of effort but lack of ownership. When a role is not written down, it does not get done. When it is written down and reviewed months in advance, it usually does.
“A generator that nobody tested in April doesn’t care how good your intentions were in September,” Rodrigues said.
What guests should expect from it
Rodrigues said the point of the commitment is not to promise guests nothing will go wrong. It is to promise a level of preparation that keeps small disruptions from becoming large ones.
“Guests don’t need a hotel that pretends storms don’t happen here,” he said. “They need one that already knows what it’s doing when one does.”
He said the readiness cycle also covers routine off-season maintenance, like checking window seals and drainage, since those checks matter as much as any emergency supply list.
A practice built for repetition
Rodrigues said he expects to run the same four-checkpoint cycle every year going forward, adjusting details as staff and property needs change but keeping the structure fixed.
“The plan should get better every year,” he said. “The calendar shouldn’t change.”
He said hotels in Florida do not get to choose whether hurricane season happens. They only get to choose how ready they are for it, months before anyone is watching a spaghetti model on the news.

Main Plumbing Services: Why Miami Homeowners Need a Plumber That Answers When Emergencies Happen
Miami, FL, United States, 19th Sep 2026 — A burst pipe, backed-up sewer line or serious leak does not wait for regular business hours. For homeowners and businesses across Miami-Dade County, a plumbing emergency can happen late at night, on a weekend or even during a holiday.
That is why Main Plumbing Services has built its business around being available when customers need help most, offering 24/7 emergency plumbing services, 365 days a year throughout Miami and surrounding Miami-Dade communities.
Serving the area for more than 12 years, the Miami-based company provides residential and commercial plumbing services ranging from emergency repairs and drain cleaning to water heater installation, sewer line work, leak detection and camera inspections.
When a Plumbing Emergency Cannot Wait Until Morning
Some plumbing problems can be scheduled for another day. Others cannot.
A burst pipe can release large amounts of water into a property. A blocked sewer line can cause wastewater to back up into a home or business. A major leak can continue causing damage while a property owner searches for someone who is available to help.
Main Plumbing Services specifically provides emergency plumbing coverage for situations such as burst pipes, sewer and drain backups, major clogs and other urgent plumbing problems.
The company’s emergency service operates around the clock, including holidays, with plumbers available to respond to calls throughout most of Miami-Dade County.
For residents searching for a 24/7 plumber in Miami, that availability can be particularly important when a plumbing problem cannot safely wait for the next morning.
More Than 12 Years Serving Miami-Dade County
Main Plumbing Services was established by professionally licensed plumbers more than 12 years ago with a focus on serving Miami-Dade County.
The company has built its services around residential and commercial customers, with a team of licensed and insured plumbers trained to handle jobs ranging from straightforward repairs to larger plumbing installations.
Its service area includes Miami, Brickell, Downtown Miami, Key Biscayne, Miami Beach, Coconut Grove, Coral Gables, Little Havana, Biscayne Park, South Miami, Kendall and other communities throughout Miami-Dade County.
That local focus is an important part of the company’s identity.
Rather than treating every plumbing problem as the same, Main Plumbing Services says its team explains the issue to customers and provides recommendations based on the work required.
Finding the Problem Before Starting the Repair
One of the challenges with plumbing problems is that the visible symptom is not always the actual source.
A drain may be clogged farther down the line. A leak may be hidden behind a wall or beneath a fixture. A sewer problem may involve an obstruction that cannot be identified through a basic visual inspection.
Main Plumbing Services uses several diagnostic technologies to help identify these problems.
Its services include camera inspections, leak detection, pipe locating and mapping, and hydro jetting for certain drain and pipe blockages.
Camera inspections can allow plumbers to examine the inside of pipes without immediately resorting to invasive work. Hydro jetting can be used to clear difficult blockages by using high-pressure water to clean the inside of pipes.
The goal is simple: understand what is happening before deciding how it should be repaired.
Plumbing Services for Both Homes and Businesses
Emergency plumbing may be what brings a customer to Main Plumbing Services, but it is only one part of the company’s offering.
The company provides a broad range of residential and commercial plumbing services, including general plumbing repairs, bathroom plumbing, kitchen plumbing, pipe installation, sewer line repair and replacement, drain cleaning, hydro jetting, leak detection and water heater services.
It also handles toilet repairs, garbage disposal repair and replacement, plumbing fixture installations and other common plumbing needs.
For water heaters, the company repairs and replaces both electric and gas systems and also offers tankless water heater upgrades for customers interested in a more energy-efficient option.
This broad range allows customers to contact the same plumbing company for both urgent problems and planned repairs or installations.
Clear Pricing Matters When Something Goes Wrong
A plumbing emergency can already be stressful without adding uncertainty about what the final bill might look like.
Main Plumbing Services says its mission is to offer competitive plumbing prices without sacrificing customer service. The company also highlights no hidden costs, trustworthy service and free consultations among its reasons for customers to choose the business.
That approach is reflected in the customer experience the company describes on its website.
Customers are encouraged to have the plumbing issue explained to them and receive recommendations before proceeding with the work.
For homeowners dealing with an unfamiliar plumbing problem, knowing what is wrong and understanding the available repair options can make the situation considerably easier to manage.
A Local Reputation Built Over Years of Service
For a service business entering people’s homes and businesses, reputation matters.
Main Plumbing Services currently highlights a 4.9 Google rating on its website, with customer testimonials describing the company’s plumbers as professional, knowledgeable, responsive and fair in their pricing.
One customer described contacting the company for advice about repairs that could be handled independently before eventually bringing in the professionals for a larger hidden-leak problem.
Another long-term customer said the company had been used for multiple plumbing problems and installations and praised the team’s responsiveness, knowledge and pricing.
Other reviews mention plumbers arriving when promised, explaining the work and resolving plumbing problems professionally.
For Main Plumbing Services, these experiences reinforce the company’s stated focus on professionalism, skill and customer service.
Preparing for the Plumbing Problems Homeowners Least Expect
Many homeowners do not think about their plumbing system until something stops working.
That can make preventative inspections and early repairs valuable.
A slow drain can be an early sign of a developing blockage. A small leak can indicate a larger problem. An aging water heater may eventually require replacement. Repeated sewer backups may point to an issue farther down the line.
Main Plumbing Services provides diagnostic, repair and replacement services designed to address these problems at different stages.
By offering everything from routine plumbing repairs to sewer line replacement and water heater installation, the company aims to give Miami-Dade homeowners one local resource for their plumbing needs.
Built for Miami-Dade’s Emergency Plumbing Needs
Miami homeowners have plenty of plumbing companies to choose from, but emergency situations can quickly narrow those options.
When a homeowner needs assistance at midnight, on a Sunday or during a holiday, availability becomes just as important as the service itself.
Main Plumbing Services has made that around-the-clock availability a central part of its business.
With licensed and insured plumbers, more than 12 years serving Miami-Dade County, emergency service 365 days a year and a broad range of residential and commercial plumbing capabilities, the company continues to position itself as a local resource for customers who need plumbing help when they need it most.
For homeowners, the best time to find a reliable emergency plumber may be before the emergency happens.

The planned feature would let users create a temporary messaging identity for a proposed $3 fee, without registering a phone number, SIM card, or email address.
United States, 19th Sep 2026 — Z-Text LLC, developer of a privacy-focused blockchain messaging application built on BitcoinZ, is developing a disposable messaging identity. The planned feature would allow users to create a temporary, cryptographically separate identity, use it for messaging, and remove the identity’s local key when it is no longer needed.
The feature extends Z-Text’s existing account architecture, which does not require a phone number, SIM card, or email address for identity creation. Z-Text is currently in private beta as the company prepares for a planned early October 2026 application release.
Key facts
- Planned disposable messaging identity, proposed price of $3
- No phone number, SIM card, or email address required for the identity
- Built on the BitcoinZ blockchain, designed to use zk-SNARKs-based privacy technology
- The disposable identity and message content are separate
- Removing the local key removes access to that identity; it does not delete blockchain data
- Z-Text remains in private beta; no independent security audit completed to date
- Funded, on-chain bug bounty program, at least one verified payout on record
A temporary identity without a permanent profile
“A temporary identity can be useful when someone does not want a short-term contact or conversation connected to their primary identity,” said Eric Pierrot, founder of Z-Text LLC. “The feature follows the same design principle as the rest of Z-Text: messaging does not require a phone number.”
The disposable identity is designed to separate a temporary identity from a user’s primary Z-Text identity. When the user removes the disposable identity, the local key is destroyed. This affects the user’s future ability to access the identity, but it does not erase content already recorded on the BitcoinZ blockchain.
Z-Text does not claim that disposable identities make blockchain messages disappear. The company’s position is that shielded permanence and removal of local access are different privacy properties.
Five functions in one application
Z-Text combines private messaging, a crypto wallet, password management, on-chain Channels, and disposable identities in one application.
The application uses identity derived from a 24-word seed phrase rather than a phone number, email address, or SIM card. Z-Text also states that it uses zk-SNARKs-based privacy technology and a hybrid key-exchange design involving ML-KEM-768 and X25519.
Z-Text has published a technical threat model describing the product’s design and known limitations. The company is also operating a funded bug bounty program while preparing for an independent security audit.
Context: identity requirements elsewhere
India’s Department of Telecommunications requires several major messaging apps to continuously reverify SIM presence, and the U.S. FCC has an open proceeding (Docket 17-59/02-278) that would require government ID before phone-line activation. Because Z-Text does not require a phone number for account creation, those phone-line requirements do not apply to that specific onboarding method.
Current status
The disposable-identity feature is in active development and is not being presented as a completed, independently audited feature. Z-Text is currently available through a private beta program.
A technical explanation of the planned feature is available at z-text.org/disposable-private-messaging-no-phone-number.
About Z-Text
Z-Text is a privacy-focused application combining private messaging, a crypto wallet, password management, Channels, and disposable identities. The messenger is built on BitcoinZ and is designed around shielded blockchain communication, zk-SNARKs-based privacy technology, and identity creation without a phone number, email address, or SIM card.
Z-Text has published its threat model, including known limitations, and operates a live bug bounty program.
