Lumino Ceremony: Building the Privacy Protection Infrastructure
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.

Noorcommunications Emerges as Delhi’s Most Trusted One-Stop Destination for PS4, PS5, iPhone, Samsung and Google Pixel Repairs
New Delhi, India, 11th May 2026, ZEX PR WIRE — There’s a particular kind of frustration that comes with a broken device. Your PlayStation won’t power on the night before a weekend. Your iPhone screen cracks on a Monday morning. Your Samsung mid-range phone — the one you rely on for everything — suddenly goes dark. For millions of people in Delhi, finding someone genuinely trustworthy to fix these problems has always felt like a gamble. Noorcommunications is changing that.

The New Delhi-based electronics repair company has quietly built one of the city’s most comprehensive device repair operations — handling everything from gaming consoles to premium smartphones under one roof, with technicians who actually know what they’re doing. And more recently, word has been spreading fast.
Gaming console repair is one of those categories where bad service can do more damage than the original fault. Overheating issues, HDMI port failures, disc drive malfunctions — these are precision jobs. Noorcommunications’PS4 repair in Delhi service has become a go-to for gamers across the city who’ve learned, sometimes the hard way, that generic repair shops often make things worse. The team here diagnoses first, explains what’s wrong in plain language, and only proceeds once the customer is on board. No surprises, no inflated bills.
The same philosophy extends to next-gen hardware. The PS5 has a reputation for being notoriously difficult to repair — its architecture is more complex, components are harder to source, and the margin for error is slim. Noorcommunications’PS5 repair in Delhi service stands out because the technicians have invested in the right tools and the right training. Customers routinely bring in consoles other shops refused to touch — and walk out with fully functioning devices.
On the smartphone side, Samsung users make up a significant portion of the customer base. Screen replacements, battery swells, charging port issues, water damage — the range of problems is wide, and so is the range of models the team handles. Whether it’s a budget Galaxy A-series or a flagship S-series, the Samsung mobile repair in Delhi service uses genuine-grade parts and doesn’t cut corners on quality checks before handing a device back.
Google Pixel phones have a dedicated and passionate user base — people who chose the device specifically for its camera, its clean Android experience, and its software support. They’re also people who tend to ask a lot of questions before handing their phone to anyone. That’s exactly the kind of customer Noorcommunications is built for. The Google Pixel repair in Delhi service is handled by technicians who understand the nuances of Pixel hardware — from display calibration to fingerprint sensor issues — and treat every device with the care it deserves.
Then there’s iPhone — still the gold standard for premium repair expectations. Apple device owners are rightly cautious about where they take their phones, and Noorcommunications has earned a strong reputation among Delhi’s iPhone users for doing the job right. The iPhone repair centre in Delhi offers everything from cracked screen replacements and battery swaps to motherboard-level diagnostics, with transparent pricing discussed upfront and genuine-quality components used throughout.
What Actually Sets Them Apart
It would be easy to list certifications and turnaround times and call it a day. But what customers actually talk about when they recommend Noorcommunications is something harder to manufacture: honesty. The team will tell you if a device isn’t worth repairing. They won’t push unnecessary parts. They explain what failed and why, in terms that make sense. And they stand behind their work.
That approach has built something genuinely valuable in a market flooded with options — a reputation you can rely on. Customers return. They send their friends. Reviews don’t read like marketing copy; they read like relief.
Noorcommunications also understands that a broken device isn’t just inconvenient — it’s disruptive. Fast turnaround isn’t a bonus feature; it’s a baseline expectation. The team works efficiently without rushing quality, and most standard repairs are completed same-day or within 24 hours.
Looking Ahead
As device ownership in India continues to grow — and as repair costs on newer flagship models climb steadily — reliable, affordable, expert repair services are becoming more important than ever. Noorcommunications is positioned squarely at that intersection. The team is expanding its service capabilities, training continuously on new models, and staying ahead of the curve on component sourcing.
For Delhi residents tired of taking chances with their valuable devices, the message from Noorcommunications is straightforward: bring it in, get an honest assessment, and leave with something that actually works. That’s not a complicated promise — but it’s one they’ve been keeping, consistently, for every customer who walks through the door.
About Noorcommunications

EDDID Launches AI-Driven Quantitative Arbitrage Platform for Singapore Futures Fund
EDDID Financial, a subsidiary of Hong Kong–based EDDID Group, has officially launched its AI-Powered Quantitative Arbitrage Platform for the Singapore Futures Fund, marking a major step in intelligent financial innovation and futures asset management. The platform integrates cutting-edge artificial intelligence, big data, cloud computing and financial engineering to reshape investment paradigms and deliver stable, risk-controlled returns for global investors.

Built for professional institutional and high-net-worth clients, the platform leverages advanced machine learning, deep neural networks and big data analytics to identify hidden market patterns and short-term pricing inefficiencies that traditional models cannot capture. In partnership with ChatGPT and Deepseek, the system enhances pattern recognition, nonlinear fitting and real-time decision-making capabilities, supporting high-frequency arbitrage, algorithmic trading and intelligent risk management across global futures markets.
At its core, the platform adopts a quantitative arbitrage strategy system that focuses on statistical mispricing and mean-reversion opportunities rather than directional market bets. It runs four major strategies: trend following, calendar spread arbitrage, cross-commodity arbitrage and cash-futures arbitrage, enabling diversified and low-correlation returns. By executing hedging operations across related contracts, the strategy aims to capture stable profits from spread normalization caused by market frictions, liquidity gaps and information transmission delays.
The AI strategy architecture operates a closed-loop system: data input, feature engineering, AI modeling, signal generation, automated execution and real-time risk control. It ingests multi-source heterogeneous data including historical K-line, Level‑2 market data, industrial fundamentals and macroeconomic indicators. Through data cleaning, alignment, high-frequency feature extraction and dimensionality reduction via PCA, the platform ensures high-quality model input. The AI core uses ensemble learning and deep models to generate precise trading signals, with automated execution achieving millisecond-level response to seize fleeting arbitrage opportunities.
Risk management is embedded into every layer of the system. The platform monitors VaR, Delta, Gamma and other risk indicators in real time, controls position exposure, restricts trading in low-liquidity contracts, and triggers model confidence thresholds to avoid failures in structural market shifts. A circuit-breaker mechanism and mandatory stop-loss rules protect the portfolio during extreme volatility and black swan events.
Backtested from January 2018 to December 2025 across bull, bear and extreme market conditions, the core strategy portfolio achieved an annualized return of 18.7%, a Sharpe ratio of 2.15, and a maximum drawdown within 8%, with a 62% win rate and 1.8:1 profit-loss ratio. In live trading since 2023, the net value curve has grown steadily with high fitness to backtest results. The strategy capacity exceeds ¥1 billion for combined strategies, supporting medium-to-large fund management.
To maintain long-term effectiveness, the platform implements continuous model iteration: weekly retraining, concept drift detection, adaptive parameter adjustment and rigorous A/B testing. Going forward, EDDID will integrate alternative data, reinforcement learning, graph neural networks (GNN) and quantum computing to further enhance strategy depth and breadth.
With strong technological barriers, robust performance and strict risk controls, EDDID’s Singapore Futures Fund AI Quantitative Arbitrage Platform sets a new standard for intelligent futures investment. It provides global investors with stable, transparent and professional asset management services, leading the evolution of AI-driven quantitative finance in the global market.
