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.

Chef Nicola’s Guide to Choosing Authentic Parmigiano Reggiano

Published

on

Nicola’s Marketplace, an Italian specialty food retailer based in Kenilworth, New Jersey, announced Chef Nicola’s new customer guide to choosing authentic Parmigiano, helping shoppers compare aged, specialty, everyday, and assortment options for cooking, entertaining, and gifting.

Kenilworth, New Jersey, United States, 24th Aug 2026 — Nicola’s Marketplace, an Italian specialty food retailer based in Kenilworth, New Jersey, has released Chef Nicola’s guide to choosing authentic Parmigiano through its online marketplace.

The guide was created to help customers understand how different Parmigiano selections can be used for different flavors, ages, textures, and occasions. Rather than treating every wedge the same, Chef Nicola’s guide compares four options currently available through the retailer.

The 36 Month Parmigiano is the boldest selection, offering a firmer texture and more concentrated flavor. It is well suited for grating over pasta, shaving onto salads, serving with aged balsamic vinegar, or adding to a cheese board.

The Di Sola Bruna Parmigiano is positioned as a distinctive specialty option for customers who want a more refined tasting experience. It works especially well for entertaining, gifting, or building a premium cheese board.

The Di Montagna Parmigiano adds another specialty choice for customers interested in a mountain-style variety with regional character. It is a strong option for tasting boards, special occasions, and customers who want to compare more unique Parmigiano selections. 

The 24 Month Paper Wrapped Parmigiano offers a more versatile everyday choice. Compared with the 36-month selection, it is approachable enough for regular cooking while still delivering authentic flavor to pasta, soups, vegetables, antipasti, and snacks.

The Taste of Italy Parmigiano Assortment gives customers the ability to compare multiple styles in one curated selection. It is designed for tasting, gifting, and customers who want to experience differences in age, texture, and flavor side by side.

“Customers often know they want authentic Parmigiano, but they may not know which option fits their meal or occasion,” said Chef Nicola DiGiorgio, Founder of Nicola’s Marketplace. “This guide helps make that choice easier, whether they are cooking pasta, preparing a board, or sending a gift.”

The guide supports Nicola’s Marketplace’s broader focus on helping customers shop Italian specialty foods with confidence. The company offers handcrafted ravioli, artisan pasta, sauces, olive oils, balsamic vinegars, salumi, desserts, gift selections, and specialty cheeses.

About Nicola’s Marketplace

Founded by Chef Nicola DiGiorgio in 2022, Nicola’s Marketplace brings together authentic Italian flavors and farm-fresh ingredients to offer high-quality, handcrafted ravioli, sauces, cheeses, olive oils, desserts, specialty pantry items, and chef-curated gift selections. What began at local farmers’ markets has grown into a nationwide destination for lovers of artisan Italian food.

Published

on

Culpeper, VA — David Kennedy Tree & Landscaping now offers strategic tree care for homeowners across Northern Virginia. The family-owned company helps property owners plan tree work with long-term goals in mind. This approach supports healthier landscapes and better use of outdoor space.

Culpeper, VA 22701, United States, 24th Aug 2026 – Well-kept trees play a large role in how a property looks and functions. Northern Virginia homeowners often weigh several factors before scheduling tree work. They want strong curb appeal, safe yards, reliable shade, and trees that stay healthy for years. Balancing these needs takes more than a single visit. It requires a plan built around the property and its trees.

Strategic tree care starts with a clear look at each tree’s condition. This includes pruning, growth management, and ongoing health checks. Experienced arborists at David Kennedy Tree & Landscaping assess risk factors like weak limbs, root damage, or disease. They also consider how a tree fits into the larger yard. Over time, this method helps trees grow stronger and last longer, and protects features homeowners value, from shade coverage to privacy screening. Their goal stays simple, and that is to support each property’s specific needs through steady, informed care.

Many yards here face common problems that hold back their potential, such as overcrowded trees that block sunlight or crowd out other plants. These limbs can also sometimes cover windows or block scenic views. Additionally, storms can leave weak trees at risk of falling, while declining health in older trees often goes unnoticed until damage appears. David Kennedy Tree & Landscaping addresses these issues with recommendations built for each yard. Their tree experts weigh tree placement, species, and condition before suggesting next steps. This process helps homeowners avoid guesswork. It also builds safer yards that hold up better through changing seasons. Over time, this steady attention helps outdoor spaces stay functional and welcoming for the whole family.
