Lumino Ceremony: Building the Privacy Protection Infrastructure

Published

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.

RINCE All Irelands Brings Irish Dance Traditions and Generations Together in Dublin

Published

on

Independent competition at the Scientology Community Centre welcomes dancers from Ireland, England and Germany, bringing traditional and modern Irish dance onto the same stage

Brussels, Belgium, 12th Sep 2026 — Dancers from Ireland, England and Germany gathered at the Church of Scientology & Community Centre of Dublin for the inaugural RINCE All Irelands, an independent competition bringing together different organisations, generations and approaches to Irish dance.

Competitors ranged from four years old to over 50 and represented four different Irish dance organisations. The format allowed dancers who might not ordinarily meet within the same competitive structure to share a common floor, while recognising achievement from beginner level through to open championship.

RINCE grew from an initiative created to keep the Irish dance community connected during the COVID-19 lockdowns.

“We started as a magazine about Irish dance but were forced to take a break during lockdown,” said Erin Coyle, founder of RINCE. “Instead, we decided to host an online competition to raise money for various food banks. Following its success, we were asked to continue and help keep dancers’ spirits up. From there, our competitions grew in popularity and have since developed into regular events, both online and in person.”

That experience eventually led to RINCE All Irelands, conceived as an independent competition where dancers from different organisational backgrounds could perform together while maintaining the standards and identity of Irish dance.

One of the main features of the Dublin event was the Set Belt competition, which asked championship dancers to demonstrate their command of both modern and traditional forms.

Competitors first performed a modern set, allowing greater freedom in their choice of movements, followed by a traditional set performed according to established standards.

“For me, hosting the Set Belt was one of the most meaningful parts of the event,” Coyle said. “It was amazing to see dancers perform both styles to such a high standard and show how Irish dance can preserve its traditions while continuing to develop and innovate.”

The format reflected a balance familiar to many living cultural traditions: maintaining skills and standards passed down through generations while giving new performers room to develop their own abilities and expression.

Irish dance also places considerable demands on competence. Progress comes through instruction, observation, repeated practice, physical discipline and attention to detail — qualities evident among competitors across the different ages and levels represented in Dublin.

For the Scientology Community Centre, that emphasis on developing ability and recognising accomplishment also reflects principles found in The Way to Happiness, the nonreligious common-sense guide to better living written by Scientology founder L. Ron Hubbard.

Among its 21 precepts is “Be Competent”, which emphasises learning, practice and the development of skill. Other precepts encourage people to set a good example, respect others and contribute constructively to the society around them.

Ivan Arjona, representative of the Church of Scientology to the European Union, OSCE, Council of Europe and United Nations, said the event illustrated how cultural heritage, personal development and respect for diversity can reinforce one another.

“Culture remains alive because people learn it, practise it well and pass it on,” Arjona said. “The precept ‘Be Competent’ from The Way to Happiness is especially relevant to what these dancers are doing: behind every performance are learning, discipline and persistence. And when people from different organisations, generations and countries come together through a shared tradition, they show that cultural identity and respect for diversity can comfortably go hand in hand — something of particular value in today’s Europe.”

The competition also featured a Parade of Champions, recognising winners at every level from Beginner through to Open Championship.

Organisers said the opportunity to acknowledge dancers across the full competitive spectrum was particularly well received, giving younger and developing competitors a visible place alongside experienced championship performers.

The event was organised with the support of volunteers Grace Noblet, Sarah Angus, Colette McCann and Jamie Dunne, who contributed to its preparation and delivery.

Coyle also highlighted the practical support provided by the Scientology Community Centre, where she had previously organised another event.

“This was my second event at the Scientology Community Centre, and both times the planning and the event itself have gone extremely smoothly,” she said. “In the weeks beforehand, the team worked through everything we needed, from lighting and tables to the presentation of the results. When I walked into the venue on the day, everything was ready to go, which took away so much of the stress involved in running an event.”

The Church of Scientology & Community Centre of Dublin opened in 2017 as a place for Scientology religious services and as a venue for cultural, educational, charitable and community activities.

Its facilities have provided a meeting place for organisations and initiatives from across Dublin, reflecting Hubbard’s view that Scientology churches should contribute positively to the communities in which they operate and provide space for constructive cooperation.

Asia Kuzma, Public Relations Officer at the Church of Scientology & Community Centre of Dublin, said RINCE represented the kind of activity the Centre was pleased to accommodate.

“RINCE brought together children, adults, families and dancers from different organisations around something that requires dedication and creates genuine connections between people,” Kuzma said. “Irish dance shows how cultural heritage can remain strong without becoming static. Each generation develops its abilities, learns from what came before and then carries that tradition forward.”

At RINCE All Irelands, the emphasis remained on culture, accomplishment and participation.

From four-year-old beginners taking some of their earliest competitive steps to experienced dancers performing at championship level, the event presented Irish dance as a living tradition sustained not simply by preserving what came before, but by continuing to learn, practise, compete and pass those skills to others.

By bringing dancers together across organisational and national boundaries, the inaugural RINCE All Irelands also demonstrated how a shared cultural tradition can provide common ground while allowing participants to retain the identities and traditions they bring with them.

Press Release

Ronel Lamour Junior launches a self-check for South Florida homeowners before the next AC breakdown

Published

on

Why a self-check, and why now

Florida, USA, 12th September 2026,  ZEX PR WIRE, Ronel Lamour Junior has spent about 16 years working on residential and light-commercial HVAC systems across South Florida. Most of the emergency calls he takes in peak cooling season share a pattern: a problem that started small and got ignored until the system stopped altogether.

“By the time someone calls me on a Saturday because the house is 85 degrees, the actual failure usually started weeks earlier,” Ronel said. “A dirty filter, a clogged drain line, a thermostat that’s been acting strange. Most of it gives you warning signs.”

He built a short list of checks a homeowner can run in about ten minutes, without tools or technical training. He is releasing it publicly rather than keeping it as something he only mentions on service calls.

What the self-check covers

The list has five items, each tied to a common failure Ronel sees repeatedly in Florida homes:

Airflow at the vents. Weak airflow from multiple rooms often points to a dirty filter or a blocked return, not a failing compressor. Ronel recommends checking the filter first, before anything else.

Water near the indoor unit. Standing water or a musty smell near the air handler usually means a clogged condensate line. In Florida’s humidity, this is one of the most common calls he gets, and it is often caught early if someone notices the water before it damages flooring or drywall.

Outdoor unit clearance. Leaves, mulch, or grass clippings packed against the outdoor condenser restrict airflow and make the whole system work harder. Ronel suggests a quick visual check for anything piled against the unit, especially after storms.

Thermostat behavior. A thermostat that seems to lose its schedule, shows inconsistent temperature readings, or won’t hold a setting is worth noting before it fails completely, particularly for households running smart thermostats.

Unusual sounds or smells. Grinding, clicking, or a burning smell are signs Ronel tells people not to wait on. Everything else on the list is a “watch it” item. This one is a “call someone now” item.

Why he is putting it in writing

Ronel has said that trust with customers is built slowly and lost quickly. Part of how he tries to build it is by giving people enough information to know what is actually urgent and what can wait.

“I’d rather someone catch a small problem themselves than pay for an emergency call that could’ve been avoided,” he said. “And if they check all five of these and everything looks fine, that’s useful information too. It usually means the problem is something else, and I don’t have to guess when I get there.”

He also sees it as a way to cut down on unnecessary anxiety. Not every strange noise means a system is dying, and not every warm room means the compressor failed.

“A lot of people panic before they need to,” Ronel said. “If you know what you’re looking at, you make better decisions. Do you need someone today, or can this wait until tomorrow morning? That’s a real difference for a family with kids or elderly parents in the house.”

Who this is for

Ronel built the checklist with South Florida’s climate in mind specifically. Condensate line clogs, humidity-driven mold near indoor units, and outdoor units packed with storm debris are more common here than in drier climates, and he wanted the list to reflect what actually goes wrong in this region rather than generic advice.

He plans to keep the list simple rather than expand it into something more technical.

“The moment it needs a multimeter, it’s not a self-check anymore,” he said. “This is meant for someone standing in their hallway trying to figure out if they need to make a call tonight or if it can wait.”

Quebec Brokerage Qubit Insurance Announces New Data on Coverage Shortfalls as Rebuilding Costs Rise

Published

on

Montreal, Canada, September 12th, 2026, FinanceWire

Qubit Insurance, an independent, AMF-licensed brokerage serving clients across Quebec, has revealed that a significant portion of Quebec homeowners may be underinsured due to rising construction costs. In a recent review of 1,200 new client policies, the brokerage found that 38% were underinsured relative to current rebuilding costs by an average of 16%.

According to Qubit Insurance, this discrepancy can trigger a co-insurance clause built into many home insurance policies, potentially reducing claim payouts even on partial losses. Many homeowners assume their insurance will cover the full cost of rebuilding after a loss, such as a fire or flood. However, if a home is insured for less than its true rebuild cost, an insurer may only pay out a percentage of a claim that matches the percentage of coverage carried. For example, a homeowner insured at 70% of their home’s actual rebuild value could see a routine claim reduced by nearly 30%, regardless of the damage’s actual repair cost.

The problem has grown more common as rebuilding costs have climbed. The Association des professionnels de la construction et de l’habitation du Québec (APCHQ) estimates that construction costs have risen by roughly 18% cumulatively since 2023, driven by inflation in materials and skilled labor. A policy that accurately reflected a home’s rebuild cost three years ago may now be underinsuring that home by a significant margin.

“We’re seeing this constantly in client feedback right now: people who haven’t touched their property coverage limits in years, even though the actual cost to rebuild their home has increased substantially,” said Manjot Singh, Insurance Broker at Qubit Insurance, who specializes in commercial and personal lines insurance. “The frustrating part is that it’s invisible until there’s a claim; nobody gets a warning that their coverage has fallen behind.”

“In a review of 1200 new client policies this year, Qubit Insurance found 38% were underinsured relative to current rebuild cost, by an average of 16%.” 

To help mitigate the risk of underinsurance and reduced payouts, Qubit Insurance recommends that Quebec homeowners:

  • Have their home’s reconstruction cost re-evaluated at least every two years, or after any major renovations.
  • Review their dwelling coverage limit at every renewal rather than letting the policy auto-renew without adjustments.
  • Confirm with their insurer or broker whether their policy applies a co-insurance clause, and at what percentage.
  • Work with a broker who can compare reconstruction-cost estimates and coverage terms across multiple carriers.
