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.

Austin Glenn Smith Launches Private Financial Consulting Practice After Three Decades in Institutional Portfolio Management

Published

on

Veteran fund and portfolio manager opens a select advisory practice focused on disciplined, long-term wealth strategy for clients across the United States and Canada

WASHINGTON, United States — June 23, 2026 — Austin Glenn Smith, Ph.D., a senior fund and portfolio manager with more than 30 years of institutional experience, has launched a private financial consulting practice serving a limited number of individuals and families across the United States and Canada. The move marks his transition from full-time fund management to one-on-one advisory work centered on portfolio strategy, retirement and wealth planning, and disciplined, long-term investing.

For three decades, Smith managed institutional portfolios through multiple market cycles, holding senior roles with the Vanguard Management Group and Expert Edge Investments. His new practice brings that institutional rigor to private clients who want experienced, independent guidance rather than off-the-shelf products.

“After thirty years of managing capital for institutions, I wanted to bring that same discipline to a smaller number of people I can serve directly,” said Smith. “Consulting is not a step back; it is a more deliberate way to add value.”

The practice is intentionally small. Smith works with a select group of clients at a time, a structure he says allows for the depth and continuity that long-term financial decisions require. Engagements focus on building diversified, risk-aware portfolios; structuring income and legacy strategies for retirement; providing an experienced second opinion on existing holdings; and helping clients understand the reasoning behind every decision.

That emphasis on judgment over volume reflects a philosophy Smith has carried throughout his career. “Markets reward patience and punish noise,” he said. “My role is to help clients hold a steady course when it matters most.”

Smith’s international background informs his approach. Born in Oslo, Norway, and educated across the United States, Germany, Scotland, and Australia, he earned a Master’s degree from Robert Gordon University in Aberdeen and a Ph.D. in Australia before entering finance in the early 1990s. He credits an early period working alongside renowned author and investor Robert Kiyosaki with shaping his conviction that financial education and disciplined strategy, not speculation, build lasting wealth.

After years of trans-continental work between the United States and Canada, Smith settled in Washington, where his consulting practice is now based. He describes the shift as an evolution rather than a retirement, a chance to apply decades of experience at a more personal scale.

Cafe Solutions Showcases Marble Table Tops for Contemporary Hospitality Venues

Published

on

Brendale 4500, Queensland, Australia, 17th Jun 2026 – Cafe Solutions, a respected supplier of café and restaurant furniture across Australia, has showcased a selection of marble table tops designed for use in contemporary hospitality venues. The addition reinforces the company’s ongoing development of its furniture catalogue with options that address both the practical and aesthetic requirements of commercial dining environments throughout the country.

The marble table tops are available in a range of sizes and finishes suited to cafés, restaurants, bars, and other food service establishments seeking to incorporate natural stone surfaces into their interior design. Marble has maintained a consistent presence in hospitality fit-outs due to its distinct visual characteristics, including natural veining patterns that give each table top an individual appearance. The material’s longstanding association with refined dining and contemporary design has contributed to sustained interest from venue operators across a variety of Australian hospitality settings.

Cafe Solutions has noted that the decision to showcase these table tops reflects ongoing enquiries from commercial operators who are seeking furniture elements that contribute to the visual identity of their venues.
