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.

Dental.me Publishes First-Ever Fully-Verified List of Florida Dentists

Published

on

10,800+ dental practice listings will help members of underserved communities find trustworthy dental services while providing an efficient, accurate information source for insurers, employers, and state-level access programs

United States, 29th Jun 2026 — Dental.me, the independent dentist directory, today announced the publication of the first-ever fully verified list of dentists in the state of Florida. The list, which contains detailed information on 10,807 dental practices in 247 Florida cities, will help members of underserved communities find trustworthy dental services while providing an efficient, accurate information source for insurers, employers, and state-level access programs.

“Until now, there was no single resource that covered every dental practice in every Florida city,” explained Spencer Whiteclaw, CEO of Dental.me. “The information that was available tended to be incomplete, out of date, or inaccurate. Online listings are often opaque. A practice that’s been shuttered for two years still shows up at the top of search rankings, and so forth. That’s the problem we’re solving with this new list.”

The list organizes dental practices by city and specialty so potential patients can compare them on the details that matter, e.g., location, services, hours, public ratings, and the completeness of listings. Dental.me makes practice verification an essential element of its listings. “Patients get the truth. Practices get a clean lane to claim their own listings,” Whiteclaw added. The verification process is manual and painstaking.

The company invested effort and resources in developing a comprehensive list of dental practices covering smaller towns and urban neighborhoods where high-integrity data on dental services has traditionally been in short supply. The listings cover dental practices from Pensacola in the Panhandle to Key West, and from Belle Glade and Clewiston in the agricultural interior to the dense urban corridors of South Florida.

Coffee Journal Publishes 50-Stop South Africa Coffee Shop Guide

Published

on

Coffee Journal, an independent South African specialty coffee publication founded by Bibi Burness

Randvaal Meyerton, Gauteng, South Africa, 29th Jun 2026 – Coffee Journal, an independent South African specialty coffee publication founded by Bibi Burness, announced the publication of its new 50-stop South Africa coffee shop guide, a nationwide editorial feature that spotlights specialty cafes, roasteries and coffee-growing estates across all nine provinces. First published June 18 and presented as a living resource for coffee travelers and local readers, the feature is designed to widen the conversation beyond the country’s largest coffee hubs and toward a more geographically representative view of South African specialty coffee.

The article frames the project as a bucket-list style guide rather than a leaderboard. According to the published methodology inside the feature, every province receives a place on the list, while the country’s biggest coffee cities are capped to make room for smaller towns, regional roasteries and farm destinations. The article states that Cape Town entries were capped at five, Johannesburg at five and Durban at three, a structure intended to create room for coffee destinations in places such as the Karoo, the Midlands, the Soutpansberg and the Port Edward area.

That editorial choice gives the release a clear news angle: a new national coffee guide that deliberately shifts attention away from metro-heavy ranking formats. In practice, the list becomes part travel guide, part editorial map and part discovery tool for readers who want to understand how specialty coffee is distributed across the country. By treating coffee as both a hospitality category and a regional culture story, Coffee Journal positions the feature as relevant to consumers, tourism stakeholders, roasters and destination businesses alike.

The feature also sets out defined selection criteria. The article says the list favors specialty over chains and story over hype, with priority given to venues that offer a compelling reason to travel, including working roasteries, award-winning baristas, distinctive cafe environments and coffee farms where visitors can engage with production more directly. The guide highlights three coffee-growing estates in particular — Beaver Creek in Port Edward, Sabie Valley in White River and Citimba in Louis Trichardt — presenting them as rare opportunities to experience South African coffee from the tree rather than only in the cup.

The guide is not presented as a closed editorial product. Instead, Coffee Journal invites readers to leave Traveller Notes, submit Go or Don’t-go verdicts and suggest shops that deserve inclusion in future updates. That built-in feedback layer gives the article continuing editorial relevance after publication and creates a transparent mechanism for expansion. It also supports return visits by encouraging readers to contribute practical details such as what to order, what to expect and which overlooked destinations should move into the next round of coverage.

Coffee Journal’s broader editorial platform strengthens the release’s credibility. The publication describes itself as independent, South Africa-based and not funded by roasters or brand partnerships, while its site includes consumer education tools such as the grind guide, city-based coffee coverage including Cape Town coffee roasters, and a published explanation of how Coffee Journal scores SA specialty roasters. Together, those resources position the new list inside a wider editorial ecosystem focused on coffee discovery, home brewing and transparency.

The article also includes a statement from Burness that captures the editorial rationale behind the project: “Every province in this country has someone quietly roasting extraordinary coffee. You just have to go looking.” That line gives the release a concise, fact-based quote already published on the site and ties the guide to a broader message about under-recognized regional talent in South African coffee.

For the specialty coffee sector, the list may be significant because it organizes discovery around national spread rather than density in a handful of cities. Many coffee roundups concentrate heavily on Cape Town and Johannesburg. Coffee Journal’s structure takes a different approach by making provincial representation part of the editorial rule itself. That approach can improve visibility for smaller operators and lesser-covered areas while also giving travelers a clearer sense of how coffee culture appears across multiple regions, not just established urban centers.

The release also aligns with Coffee Journal’s identity as a specialty coffee publication that combines editorial curation with practical user participation. Its homepage presents the brand as a place to track espresso, discover South African roasters and learn the craft, while the about page says the publication was founded in 2026 to create a central home for the country’s specialty coffee scene. In that context, the 50-stop guide functions as both a standalone article and a strategic content asset that complements the site’s directories, brew guides and transparency-based reporting.

The new feature is now available on the Coffee Journal website, where readers can browse the full list, review province-by-province selections and contribute notes for future updates. Additional coverage of South African roasters, brewing resources and editorial coffee guides is available through Coffee Journal.
