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.

BLS Clinic Myeongdong Offers EXOSMART and PRP Procedures with Personalized Focus

Published

on

Dr. Jung emphasizes individualized consultations and informed treatment decisions.

Seoul, South Korea, 12th Oct 2026 – As interest in aesthetic medicine continues to grow, patients are exploring various treatment options based on their individual skin conditions and personal needs. With different technologies and procedures becoming available, understanding how each treatment works and discussing the relevant considerations with medical professionals has become an important part of the decision-making process.

Located in Seoul, South Korea, BLS Clinic Myeongdong offers EXOSMART and Platelet Rich Plasma (PRP) procedures as part of its aesthetic medical services. Under the guidance of Dr. Jung, the clinic provides consultations that take each patient’s skin condition, medical history, previous treatments, and individual concerns into consideration before determining whether a procedure is appropriate.

EXOSMART is a medical device used to process blood collected from a patient through centrifugation and ultrafiltration. These processes are used to separate and prepare blood components, with specific applications determined according to the device’s approved intended use and medical assessment.

PRP, or Platelet-Rich Plasma, refers to plasma containing a concentrated number of platelets obtained from a patient’s own blood. Platelets contain growth factors involved in various biological processes, and PRP has been studied across several medical fields. However, clinical evidence regarding its applications in aesthetic medicine varies depending on the treatment purpose and method.

Although EXOSMART and PRP both involve blood-derived components, their preparation processes and specific applications differ. Understanding these differences is an important consideration when evaluating available treatment options.

At BLS Clinic Myeongdong, Dr. Jung emphasizes the importance of reviewing individual skin conditions, medical history, and personal expectations before proceeding with aesthetic treatments.

For patients considering EXOSMART or PRP procedures, the clinic provides information about the treatment process, potential discomfort, possible side effects, and relevant precautions. The suitability of each procedure is determined through medical consultation.

Myeongdong is one of Seoul’s major shopping and tourism districts, welcoming both domestic and international visitors. The area is also a convenient destination for overseas travelers interested in learning more about Korean beauty and aesthetic medical services.

For international patients, factors such as travel schedules, recovery considerations, and post-treatment care may influence their treatment decisions. Discussing these matters with medical professionals before undergoing a procedure is particularly important for patients visiting Korea for a limited period.

BLS Clinic Myeongdong continues to provide EXOSMART and PRP related procedures as part of its aesthetic medical services, with an emphasis on patient education, individualized consultation, and informed treatment decisions.

Beyond the Customs Declaration: Gorian Aduanas Takes a Specialist, Bespoke Approach to Customs Clearance and Complex International Imports

Published

on

Spain, 12th Oct 2026 – Founded in Málaga southern Spain with a clear vision to assist Spanish, European and international clients with complex customs clearance and international trade operations involving Spain and Europe, Gorian Aduanas has developed a specialist tailored approach built around knowledge, strategy and tailored solutions rather than routine paperwork.

Customs clearance is often described as an administrative process, and they would not be mistaken to think this: prepare the documents, submit the declaration, pay the applicable duties and taxes, and release the goods. Move onto the next! For straightforward and simple shipments, that may be all that is required. But international imports are not always straightforward and when we introduce high valued items together with tax exemptions, they are far from simple.

A six-figure yacht arriving from outside the European Union, a high value sports car requiring EU technical, legalisation and registration procedures, a collection of artworks entering Spain for an exhibition, a family relocating their permanent residence to Spain with personal belongings, or a technically controlled product requiring licences, certificates and coordination with different authorities can involve considerably more than completing a customs declaration.

This is the environment in which Gorian Aduanas thrives in and has built its reputation to date.

The company provides authorised customs representation and specialist solutions for international operations involving Spain and European markets, with experience across several specialist areas including; yachts and recreational craft, luxury and sports vehicles, works of art, transfer of residence and relocation to Spain, controlled goods, technical imports and complex international transport projects.

The common denominator is not the product. It is the complexity of the operation.

That principle sits at the heart of Gorian Aduanas.

As a company Gorian does not attempt to specialize or cover every possible product or every possible sector. Instead, it focuses on the areas where it has developed genuine specialist knowledge and experience, particularly where customs clearance intersects with the afore mentioned areas and requiring technical documentation, import taxation, regulatory requirements, logistics or other specialist procedures. This distinction is important.

The value of a customs specialist is not simply measured by how quickly a declaration can be submitted. In more complicated operations, the real value lies in understanding how the operation should be structured before the declaration is ever made. What documentation is required? Which customs

procedure is appropriate? Are there exemptions or reliefs that may apply? How should the goods be valued? Are there technical or regulatory requirements that need to be dealt with first? Which authorities may need to become involved? Does the proposed route make sense from a customs and tax perspective? These are the questions that can determine whether an international import becomes a well-planned operation or a costly problem.

From a clear vision in Spain to a wider international reach

Gorian Aduanas was founded in Málaga in 2022, but its geographical vision was established from the outset. The intention was not to create a company serving only its immediate local market. The objective was always to develop the capabilities and specialities to assist clients throughout Spain, while also supporting international clients whose customs and international trade operations involve Spain and European markets. That wider reach was quickly developed as the company grew and clients learned of their unique skillsets.

Today, Gorian Aduanas serves clients throughout Spain and works on international customs projects where Spain forms part of a wider European operation. Its origins in Málaga remain an important part of the company’s history, but Málaga was the starting point, and was never going to be the boundary. The same philosophy applies to its professional network.

Over the years, Gorian Aduanas has built relationships with experienced professionals across different specialist fields. When a particular project requires expertise beyond customs clearance itself, the company can bring the appropriate specialist into the operation and coordinate the different elements around the client’s requirements. The objective being simple: the client should not have to work out independently who needs to be involved or how the different parts of the operation fit together.

Goran’s foundations were firmly set in the nautical sector

Although Gorian Aduanas is not exclusively a nautical customs clearance agency, yachts and recreational craft represent a very large and important part of its specialist portfolio and have played a significant role in shaping the company’s technical approach.

The story goes back to the beginning of 2012, when the company’s director established a business focused on marine surveying and European CE inspection of recreational craft. As a qualified marine surveyor, he developed specialist knowledge of vessels and their technical documentation before working with select Notified Bodies and subsequently moving into the European CE inspection field for recreational craft. That experience became particularly valuable when Gorian Aduanas was established a decade later.

The customs company was not simply a continuation or merger of the earlier business. Rather, the knowledge, experience and practical understanding developed through that work became part of the foundation on which Gorian Aduanas was built, alongside newly incorporated customs representation expertise. This combination created an unusual perspective. Gorian could approach a yacht import not only from the customs viewpoint, but with a full understanding of the vessel itself and interpretation of its documentation.

Where customs knowledge meets nautical knowledge

The benefit of this approach became increasingly apparent through work with yacht owners, captains and other clients importing vessels into Europe. Clients could sometimes find themselves dealing with customs representatives who understood the standard customs process but had little to no understanding of the nautical sector or the vessel itself, putting at risk the customs process altogether.

Yacht documentation has its own technical peculiarities. Understanding how that documentation should be interpreted and presented effectively to customs authorities can affect the way an import operation is approached. The vessel’s technical characteristics, history, ownership, intended use and supporting documentation can all be relevant.

In many cases, the difficulty was therefore not simply a question of preparation or communication. It was the absence of specialist knowledge capable of connecting the nautical and customs aspects of the operation. Gorian made sure that they could communicate effectively, and more importantly technically, with all members involved in the process. It is in this area in which Gorian Aduanas developed a particular strength.

The company has assisted clients and captains with permanent yacht imports, Temporary Admission for yachts and recreational craft, customs clearance and tax procedures, technical documentation and European CE-related requirements, among other operations. Its director’s background in marine surveying and recreational craft CE inspection also means that technical yacht documentation can be approached from a perspective that goes beyond simply checking whether a document has been attached to a customs file, but actually understanding the document that is being presented and its contents. This is often beneficial when a “non-marine orientated” customs authority is questioning documentation or details, Gorian can explain the documents to the official and lead him to the answers he seeks, without having to delay the process by going back to the client with the officials’ questions.

For recreational craft requiring CE compliance work, Gorian’s technical capability includes inspection and preparation of the relevant technical file, working within the European conformity assessment framework and with the appropriate Notified Body involved in the certification process. That technical foundation has become an important part of the company’s wider customs approach.

Not just yachts: specialist bespoke solutions across high value and technically demanding imports

While the nautical sector remains core pillar of Gorian Aduanas’ activity, the company’s specialist work extends well beyond boats.

One important area is the importation of luxury and sports vehicles, particularly where a vehicle arriving from outside the EU requires more than a standard customs declaration. Depending on the vehicle and the circumstances, the operation may involve customs valuation, import taxation, technical documentation, homologation, registration requirements, certificates or other procedures before the vehicle can be legally used in Spain.

The same principle applies to works of art and cultural items. Gorian Aduanas has assisted with the importation of paintings, sculptures and other artworks for exhibitions, galleries, public institutions and private individuals. These operations can involve temporary imports, ATA Carnets, definitive imports and the correct application of customs and tax treatment depending on the circumstances.

Another core specialist area is transfer of residence and relocation to Spain. For individuals moving to Spain from outside the European Union, the importation of personal belongings and vehicles, in qualifying circumstances, vehicles can involve specific customs procedures and potential relief from import duties and taxes. This is a process that must be solicited by the customs clearance representative on your behalf, done incorrectly by a less or non-experienced person, import taxes might be claimed!

These operations require more than arranging transport. The individual’s circumstances, dates, ownership history, documentation and eligibility for the relevant reliefs need to be considered before the shipment is structured. Gorian Aduanas customs clearance has assisted clients with these relocation operations, including cases involving substantial personal assets, vehicles and household belongings that can run into the hundreds of thousands of US Dollars in value. Especially when yachts, aircraft or multiple cars are involved.

The company also works with controlled and technically demanding goods, where customs clearance may require coordination with other government departments, inspectors or regulatory authorities. This can include products requiring licences, certificates, technical documentation or specific approvals, as well as merchandise subject to additional sanitary, quality-control or regulatory requirements. In these situations, customs are only one part of the operation.

A good solution begins way before the customs declaration is prepared

This is one of the fundamental differences in the way Gorian Aduanas approaches its work. The starting point is not normally a form. It is a detailed conversation.

The company first seeks to understand what the client is trying to achieve, what is being imported or exported, where it is coming from or where it is going, who owns it, what documentation exists and what particular circumstances and details surround the goods that may affect the operation. The documentation is then studied to identify the applicable customs and tax position, potential problems, missing information and possible solutions. Only after that assessment can a sensible strategy be established and laid out to the client in writing.

In some operations, the correct solution may seem straightforward. In others, it may involve several phases, different authorities, technical specialists, transport providers, customs procedures or supporting documentation. The objective is not to create unnecessary complexity, quite the opposite, it is to identify and understand the right complexity before it becomes a problem. This approach also means looking carefully at the benefits available under the applicable rules or laws.

Import duties and taxes are not always simply a cost that has to be accepted. Depending on the circumstances, customs legislation can provide reliefs, exemptions or alternative procedures. The important point is to identify what is legally available and establish whether the client qualifies for it fully, partially or not at all before the operation is undertaken. That is where strategy becomes part of good customs clearance representation.

From customs clearance to project coordination

Some more complex bespoke international operations also require Gorian Aduanas to look beyond customs clearance. Yacht transportation is a particularly good example of this.

Moving a 16-, 20- or 40-metre vessel from an international origin to Europe is not simply a matter of arranging a ship and then completing customs paperwork when it arrives. Ocean transport, port arrival, specialist lifting, loading, cradles, dimensions, road transport, route planning, timing, documentation and customs procedures can all have to work together. Gorian Aduanas has organised and coordinated complex yacht movements involving origins including China, Turkey, the United States, the United Kingdom and the United Arab Emirates.

Where required, the company coordinates specialist transport providers on behalf of the client, integrating the transport operation with the customs and technical requirements of the project. The company does not need to own the trucks, ships or transport equipment to add value to this process.

When required and contracted, its role is to understand what the project requires, identify the appropriate providers and coordinate the different elements so that customs, transport and technical requirements are considered as one operation rather than as isolated tasks. This wider project management approach empowers the client and has also proved useful in other complex imports, particularly where unexpected problems, storage costs, regulatory requirements or multiple authorities are involved.

Experience measured in tailored solutions, not simply shipment value

Gorian Aduanas does not define its work by a particular minimum shipment value. Nor does it seek to compete simply on the number of declarations processed. The company’s work ranges across operations where the financial value, technical requirements, regulatory implications or potential consequences of getting the customs treatment wrong make specialist planning important.

Some projects involve high value assets. Others are defined less by their financial value than by the complexity of the documentation, the number of parties involved or the consequences of choosing the

wrong customs procedure. The objective is to understand the operation, identify the available routes and develop the most appropriate lawful strategy for the client.

That can mean finding a bespoke solution to a customs problem that has already stopped an operation, identifying a legitimate tax or customs benefit that had not previously been considered, finding an appropriate customs storage solution, preparing the documentation required by an authority, or coordinating several professionals around one project. In some cases, client’s approach Gorian after an operation has stalled or an issue has arisen with other customs representatives due to their lack of knowledge.

The company’s role in those circumstances is not to criticise what has happened before, but to learn where the client find himself in the process, understand the situation, identify the options and what can still be done and determine the most appropriate way forward.

Specialist customs knowledge, supported by the right people

Gorian Aduanas is the first to recognise that no specialist company can realistically have every technical discipline under one roof. What matters is knowing where additional specialist knowledge is required and knowing who can provide it.

Over the years, the company has developed a trusted professional network covering different areas relevant to international trade, customs, technical compliance, transport and other specialist requirements. When a client’s circumstances call for additional expertise, the appropriate professional can be brought into the project and the different elements coordinated around the overall strategy.

This allows Gorian to remain focused on what it does best while ensuring that a complex operation does not become fragmented between professionals who are working independently without understanding the wider objective. The result is a more joined-up approach.

One company, a specialist mindset

The sectors in which Gorian Aduanas operates may appear different at first glance. A yacht is not a sports car.

A sculpture is not a residency relocation.

But from a customs and international trade perspective, they can share the same fundamental challenge: the operation being presented, very often, cannot always be treated as routine. Each may require a combination of customs knowledge, documentation, taxation, technical understanding, regulatory compliance, logistics and careful planning. That is why Gorian does not try to cover every product or every sector, as simple at that sector may seem on the surface.

It focuses on the areas where it has developed genuine specialist knowledge and experience, and aims to deliver that expertise to the highest standard. The company’s philosophy can be summed up simply:

“ We don’t simply offer services. We create solutions. “

For Gorian Aduanas, that means looking beyond the customs declaration, understanding the whole operation and calculating how the different pieces fit together through a tailored solution.

Looking beyond the just the customs paperwork

As the globe gets better connected, international trade is consistently on the rise and is becoming increasingly interconnected, while the assets and products moving across borders can be increasingly

sophisticated. A customs declaration remains an essential part of the process, but for many international imports, it is only one part.

The difference between a routine clearance and a successful operation can lie in what happened before the declaration was submitted: whether the right questions were asked, whether the documentation was properly understood, whether the applicable customs procedure was correctly identified, whether available reliefs were considered, whether technical requirements were anticipated and whether the different professionals involved were coordinated and working towards the same objective.

That is the space in which Gorian Aduanas has chosen to operate.

Founded in southern Spain, on the Costa del Sol, with a vision that extended beyond its immediate surroundings, this multilingual company has developed into a specialist customs and international trade partner serving clients throughout Spain and managing projects with international dimensions across Spain and European markets. Its experience may have strong roots in the nautical world, but the underlying philosophy is broader.

Understand the client and his needs. Understand the goods. Understand the rules and regulations.

Identify the possibilities and benefits. Build the strategy. Then execute it properly.

For Gorian Aduanas, that is what customs clearance looks like when it is treated not simply as paperwork, but as part of the wider solution.

Always Looking Ahead: A New Sector on the Horizon in Customs Clearance

While Gorian Aduanas continues to develop its existing areas of specialist expertise, this dynamic company is also looking towards an exciting new sector: aviation and aeronautics.

The intention is to extend Gorian’s specialist customs and international trade capabilities into the world of helicopters and general aircraft, an area where international movements can involve highly technical assets, complex documentation, significant values and a very particular regulatory environment.

The project is still in the implementation stage, and the company is currently developing the necessary knowledge, relationships and specialist capabilities required to enter the sector with upmost confidence rather than simply adding aviation to a list of services with hopes it goes well!

This is a good spot to draw this article to a close, for Gorian, that is the important distinction. New sectors will only be pursued where the company believes it can develop genuine specialist knowledge and bring real benefit to potential clients by offering the same strategic, tailored approach that has defined its work in other complex areas.

Aviation is an exciting new chapter for Gorian Aduanas. “We are only getting started — so watch this space”.
