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.

Maintaining Property Value Through Specialized Cleaning: Vantique Cleaners Offers Solutions Across Australia

Published

on

Australia, 14th Oct 2026 – Keeping a property in good condition requires consistent attention to surfaces, flooring, windows, and other areas that experience regular use. For landlords, property managers, homeowners, and tenants, professional cleaning can form part of a broader approach to property care. Vantique Cleaners provides a range of residential cleaning services designed to support these needs across Sydney, Melbourne, Perth, Brisbane, and surrounding suburbs.

From routine house cleaning to specialized floor and carpet care, the company offers services suited to different property types and cleaning requirements. Its approach combines experienced cleaners, professional-grade equipment, and eco-friendly cleaning products to help customers maintain clean and comfortable environments.

A Broader Approach to Residential Property Care

Regular cleaning helps address the everyday buildup of dust, dirt, and grime that can affect the appearance of frequently used spaces. However, some areas require more specialized attention than standard household maintenance provides.

Carpets, tiled surfaces, grout lines, windows, and outdoor driveways can present different cleaning challenges. Vantique Cleaners offers services covering these areas, including carpet cleaning, tile and grout cleaning, window cleaning, pressure washing, driveway cleaning, and floor polishing.

By offering multiple cleaning options, the company enables customers to consider the specific needs of their properties and identify appropriate services. Homeowners may require periodic deep cleaning, while landlords and property managers may need support preparing a property for new occupants.

Specialized Cleaning for Rental Properties

Rental properties experience changing cleaning requirements as tenants move in and out. Preparing a property for a new occupant may involve addressing accumulated dirt, cleaning high-use areas, and ensuring that different surfaces receive appropriate attention.

Professional end of lease cleaning provides an option for tenants and property owners seeking assistance with this process. A detailed cleaning plan can help address kitchens, bathrooms, floors, and other areas that may need attention before a property handover.

The scope of professional end of lease cleaning services can vary according to the property’s size, condition, and agreed service package. Customers should confirm which tasks are included and review any specific requirements established by their rental agreement or property manager.

For landlords, maintaining consistent cleaning standards between tenancies can support a more organized property management process. For tenants, arranging cleaning before moving day can help them manage one of the many responsibilities associated with relocating.

Giving Carpets, Tiles, and Floors Appropriate Attention

Different flooring materials require different cleaning approaches. Carpets can collect dust and everyday debris, while tile surfaces and grout lines may develop visible dirt over time. Hard floors can also benefit from appropriate cleaning and maintenance.

Vantique Cleaners offers carpet cleaning and tile and grout cleaning alongside its wider residential services. Customers preparing to vacate a rental property can explore end of lease cleaning services to learn more about cleaning options relevant to their circumstances.

Where additional carpet care is needed, customers can ask about end of lease carpet cleaning and whether it is included in their selected package or arranged as a separate service.

Understanding the property’s flooring materials and condition before booking can help customers communicate their needs and establish realistic expectations for the cleaning work.

Selecting Services According to Property Needs

Not every property requires the same cleaning schedule or combination of services. An apartment may need attention to its kitchen, bathroom, windows, and flooring, while a larger house may require a broader cleaning plan. Outdoor areas, including driveways, may also need periodic cleaning depending on their condition and use.

Vantique Cleaners offers regular house cleaning, bond back cleaning, window cleaning, pressure washing, driveway cleaning, and floor polishing, allowing customers to explore services according to their requirements.

Customers can also request end of lease cleaning quotes to understand the potential cost of preparing a property. Pricing may depend on the size of the property, its current condition, the number of rooms, and any additional tasks requested.

Providing accurate property details when requesting a quote can help clarify the proposed scope of work. Customers should also ask about appointment availability if cleaning must be completed within a particular timeframe.

An Established Cleaning Service Across Major Australian Cities

Vantique Cleaners reports serving more than 1,200 satisfied clients, employing over 50 cleaners, and completing more than 8,000 cleans. The company serves customers across Sydney, Melbourne, Perth, Brisbane, and surrounding suburbs.

Its combination of general and specialized cleaning services provides an option for customers seeking assistance with ongoing property maintenance or more detailed cleaning projects. By discussing their priorities and confirming the services available for their location, customers can plan cleaning arrangements around their property requirements.

Vantique Cleaners Highlights Detailed Rental Property Cleaning for Tenants Preparing to Move

Published

on

Australia, 14th Oct 2026 — Preparing a rental property for its final inspection can be a demanding part of moving, requiring tenants to manage packing, relocation arrangements, and household cleaning at the same time. Vantique Cleaners, an Australian residential cleaning company, provides professional cleaning services designed to help tenants and homeowners manage these responsibilities across Sydney, Melbourne, Perth, Brisbane, and surrounding suburbs.

With a focus on detailed workmanship, customer satisfaction, and reliable service, Vantique Cleaners offers cleaning solutions for different property types and household requirements. Its services include end of lease cleaning, bond cleaning, regular house cleaning, carpet cleaning, tile and grout cleaning, window cleaning, pressure washing, driveway cleaning, and floor polishing.

Making Rental Property Preparation More Manageable

Moving out of a rental property often involves preparing multiple areas for inspection. Kitchens may require attention to grease and food residue, bathrooms can accumulate soap deposits and grime, and floors may need thorough cleaning after furniture has been removed. These tasks can become more time-consuming when tenants are working against a moving deadline.

Professional bond cleaning services provide an option for tenants who want assistance with these detailed cleaning requirements. Vantique Cleaners approaches rental property cleaning with attention to the different areas that may require care before a property is handed back.

A thorough cleaning process can help address everyday dirt and buildup that develops during a tenancy. Depending on the property’s condition and agreed service requirements, customers may seek cleaning for kitchens, bathrooms, living areas, floors, and other household spaces.

By arranging professional assistance, tenants can organize their moving schedules while leaving cleaning tasks to an experienced team.

Understanding the Importance of Bond Back Cleaning

Bond back cleaning is commonly associated with preparing a rental property for its final inspection. The process focuses on leaving the premises clean and addressing areas that may have accumulated dirt during everyday use.

For people searching for bond back cleaning, understanding the scope of the service is an important first step. Cleaning requirements can differ depending on the rental agreement, the property’s condition, and applicable tenancy rules. Establishing which areas need attention before booking can help customers select an appropriate service.

Vantique Cleaners provides bond back cleaners for customers seeking professional support during the move-out process. Its cleaning services are intended to help prepare residential properties for handover through detailed attention to household surfaces and frequently used spaces.

Although professional cleaning can support rental property preparation, a bond refund is not guaranteed by cleaning alone. Final outcomes may depend on inspection findings, the tenancy agreement, and the relevant local regulations.

Cleaning Options Beyond the Final Inspection

Although rental property preparation is an important reason to arrange a professional clean, residential cleaning needs extend beyond moving day. Regular maintenance can help households keep their living spaces comfortable, while specialized services can address surfaces that need additional attention.

Vantique Cleaners offers regular house cleaning for ongoing household upkeep, along with carpet cleaning, tile and grout cleaning, and window cleaning. For outdoor areas, its services include pressure washing and driveway cleaning. Floor polishing is also available for customers seeking additional care for suitable flooring surfaces.

These options allow customers to consider different cleaning requirements according to their property’s needs. Someone preparing to vacate a rental home may require a detailed end of lease clean, while another household may be looking for periodic assistance with routine maintenance.

The availability of multiple services through one provider can also simplify the process of arranging cleaning for different areas of a property.

A Service Approach Built Around Experience and Attention to Detail

Vantique Cleaners reports serving more than 1,200 satisfied clients, completing over 8,000 cleans, and working with a team of more than 50 cleaners. The company operates across several major Australian cities, including Sydney, Melbourne, Perth, and Brisbane, as well as surrounding suburbs.

Its approach combines experienced cleaning personnel, professional-grade equipment, and eco-friendly cleaning products. These elements support its focus on providing consistent cleaning services for homes and rental properties.

Attention to detail is particularly relevant when preparing a property for handover, as different rooms and surfaces can require different cleaning methods. Customers can discuss their needs with the company to understand the available services and determine which option is appropriate for their property.

Helping Customers Plan Their Next Move

Organizing a move involves coordinating numerous responsibilities, from arranging transportation to ensuring that a property is ready for its next occupants. Professional cleaning can help reduce the amount of work tenants need to manage independently during this transition.

Vantique Cleaners provides bond cleaning, bond back cleaning services, and other residential cleaning options for customers seeking support with property maintenance and moving preparations. Its service coverage across major Australian cities gives households in these locations an opportunity to explore professional assistance suited to their needs.
