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.

Sandromeda Unveils 10 Foot Mega Photo Booth 30-Inch Screen

Published

on

Sandromeda Music Services announces a towering 10-foot Mega Photo Booth featuring a 30-inch viewing screen, engineered for high-traffic events with fast sharing and branding options.

Grandville, Michigan, United States, 13th Sep 2025 – Sandromeda Music Services today introduced a large-format photo experience built to command attention at modern gatherings. The 10-foot Mega Photo Booth rises over busy floors and stages, pairing its height with a vivid 30-inch viewing screen to make posing and playback visible from across the room. The system is engineered to turn casual snapshots into showpiece moments, ensuring guests see themselves clearly while organizers benefit from a focal point that draws steady foot traffic.

Large-Scale Presence Designed for Impact

The new installation brings the scale of a set piece to private and corporate environments. Its towering frame and oversized display are designed to create a visual anchor that stands out amid décor, signage, and AV builds. The screen presents live previews and instant replays so participants can adjust their stance, synchronize group shots, and celebrate their captures without crowding around a small interface. The result is a constant cycle of engagement that keeps lines moving while maintaining an elevated, stage-like feel.

Built for Weddings, Corporate Functions, and High-Volume Parties

Sandromeda developed the booth for occasions where reliability and throughput matter as much as spectacle. Weddings gain a centerpiece that guests can spot from the dance floor, reducing congestion and encouraging multi-generational participation. Corporate programs benefit from a branded attraction that welcomes attendees between sessions and during receptions. Social parties see the energy of the room reflected on the large display, encouraging spontaneous posing and repeat visits throughout the event.

Elevated Visuals and Streamlined Guest Flow

The Mega Photo Booth emphasizes clarity and ease of use. The large viewing screen guides users with simple prompts and spacious on-screen controls, allowing groups to align quickly and capture wide, flattering frames. Professional-grade lighting and a stabilized capture path are tuned to maintain consistency as conditions shift, while the interface supports rapid retakes to keep lines short. Hosts can enable digital delivery methods suited to the crowd, including on-site QR retrieval and post-event gallery access, ensuring images reach guests without delay.

Branding, Creative Control, and Production Readiness

Event teams can extend their visual identity through on-screen overlays, custom start screens, and backdrop coordination, transforming the booth into a cohesive element of the overall design. The structure is optimized for quick setup and strike within typical venue load-in windows, and it runs on standard power to integrate smoothly with AV plans. Sandromeda’s staffing model supports continuous operation during peak periods, with on-site attendants helping maintain flow and assisting guests so planners can focus on the run of show.

Availability and Booking Information

The 10-foot Mega Photo Booth is now open for bookings across a range of event types and timelines. Sandromeda Music Services is scheduling dates for the current season and beyond, with consultation available to align creative treatments, floor plans, and program objectives. Organizers seeking a headline attraction that elevates participation and delivers memorable content can incorporate the Mega Photo Booth as a central feature of their next event.
