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.

Featuring the revolutionary DynaCore System, Sihoo’s newest flagship chair eliminates support loss during movement and delivers truly adaptive, personalized comfort.

Shenzhen, China, 20th Apr 2026 – Sihoo, a global leader in ergonomic furniture with 15 years of design and engineering excellence, today announced the official global availability of the highly anticipated Doro C300 Pro V2. Engineered to redefine all-day comfort, this new flagship model is the market’s first ergonomic chair to deliver true, intuitive, full-body adaptive support.

The End of Support Loss During Movement

Building on the global success of the original Doro C300, the Pro V2 sets a new standard for dynamic comfort. At its core is Sihoo’s proprietary DynaCore Full-Body Support System.

Unlike traditional office chairs that lose support the moment you move—or ergonomic chairs that demand constant readjustment—the Doro C300 Pro V2’s DynaCore system seamlessly synchronizes the backrest, lumbar support, headrest, and armrests. The result is a chair that intuitively responds to your natural movements. Whether you lean forward for focused work, shift side to side, or recline to relax, the chair maintains perfect, continuous balance.

Personalized Comfort from the First Moment

The Doro C300 Pro V2 takes personalization further with the SyncroFlex Backrest. The instant you sit down, the chair automatically maps and follows the natural curvature of your spine. Its intelligent recline path adapts dynamically to your unique body size and movement patterns, delivering a highly tailored experience with zero manual adjustments.

Next-Generation Features

The Doro C300 Pro V2 is packed with upgraded technology designed for today’s professionals, gamers, and creators:

  • Self-Adaptive Dynamic Lumbar Support 2.0 — Offers three levels of targeted adjustability for fatigue-reducing lower-back support that lasts all day.
  • 8D Bionic Armrests — Move in eight directions to provide perfect arm support whether you’re typing, gaming with a controller, or scrolling on a mobile device.
  • Ultra-Wide 3D Headrest — Delivers precise, cradle-like neck support to relieve tension during long periods of focus.
  • Weight-Adaptive Mechanism 2.0 — Automatically calibrates recline tension to your body weight, providing an ultra-smooth recline of up to 135° for a seamless transition between work and rest.

A Captivating Tale of Passion and Late-Blooming Love: Dancing With Katie by E.P. Lande

Published

on

United Kingdom, 20th Apr 2026 – Blue Crystal Literary Magazine proudly presents Dancing With Katie, a deeply evocative and emotionally layered novel by E. P. Lande, now available worldwide. Blending autobiographical elements with fiction, this compelling work explores the transformative power of dance, desire, and human connection.

At the heart of the novel is Aaron, a divorced and reflective former academic living in Vermont, whose quiet, structured life is disrupted by an unexpected calling—to dance. What begins as a simple pursuit soon becomes an all-consuming passion for the Argentine tango, a dance that awakens not only his body but his emotional world.

Aaron’s journey takes him across cities and continents—from rural Vermont to Montreal, New York, and Buenos Aires—in search of mastery, meaning, and ultimately, connection. Along the way, he encounters teachers, dancers, and a vibrant global tango community that shapes his transformation. Yet, despite his relentless pursuit of technical perfection, what Aaron truly lacks is a consistent partner—until he meets Katie.

Katie, a former ballerina with independence and emotional complexity, enters Aaron’s life initially as a dance student. What begins as a practical arrangement soon evolves into something far more intricate. Their shared hours of practice—set against the rhythm and intimacy of the tango—give rise to a relationship that blurs the boundaries between teacher and student, companionship and longing.

As Katie navigates a succession of romantic relationships, Aaron finds himself caught between restraint and desire, reflection and action. His internal struggle—marked by self-examination, jealousy, and hope—forms the emotional core of the novel. Through dance, conversations, and unspoken tensions, their bond deepens, revealing the complexities of timing, love, and missed opportunities.

In its poignant conclusion, Dancing With Katie delivers a powerful realization: that what we seek in life is often already within reach, obscured only by our own distractions and hesitations. The novel closes on a note of emotional clarity and quiet revelation, as both Aaron and Katie confront the truth of their connection.

Written with elegance, wit, and introspective depth, E. P. Lande’s narrative captures not only the sensuality and discipline of the Argentine tango but also its symbolic resonance as a dance of life—one of balance, timing, and mutual understanding. Both a romance and a meditation on self-discovery, the book appeals to readers who appreciate character-driven storytelling and emotional authenticity.

E.P. Lande, originally from Montreal and now based in South Carolina, brings a rich and varied life experience to his writing. A former academic and Vice-Dean, as well as a restaurateur and widely published short story writer, Lande has crafted a narrative voice that is both reflective and deeply human.
