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.

ChangeNOW Announces NOW AI After Resolving Website Integration Vulnerability

Published

on

Kingstown, Saint Vincent and the Grenadines, October 15th, 2026, Chainwire

On October 15, with the help of independent security researchers, we found a vulnerability affecting one of the integrations used on the ChangeNOW website. The vulnerability has now been fixed.

We currently have no evidence that it was exploited. But we also can’t assume that the researchers who reported it were the only ones to find it. Because of that, we’re looking at the different possible scenarios and warning clients about the information that could potentially have been exposed. This may include email addresses and transaction details.

Please note ChangeNOW’s transaction infrastructure was not affected, and customer funds were never at risk.

The main thing clients should watch out for now is suspicious or fraudulent messages. A phony message could reference real transactions or support to appear legitimate. If you get an unexpected message that looks like it’s from ChangeNOW, please check the sender before responding, clicking on any links or giving any information. We exclusively contact clients via support@changenow.io and we will never ask for a private key, seed phrase, or any password by email.

People contact our support and compliance teams because they trust us with information they would not share publicly, and we understand the responsibility that comes with that. We have no indication this vulnerability was exploited, but we believe it is important to warn of the possible risks rather than wait until there is total certainty.

Our clients are at the center of what we do, and we’re continuing to upgrade the protection of our products. One of the actions we are taking is the launch of NOW AI, a dedicated protection lab with a mission to raise the security standard across all ChangeNOW products. We want to apply the same technology to the defensive side to spot danger earlier and bake stronger security into our products, especially as AI makes malicious action easier to automate and expand.

Today’s case only made the need to move faster more obvious and it accelerated the launch of NOW AI. We’ll publish more details on our plans, what it covers, and how it will be used across ChangeNOW on a dedicated page on our website soon. Stay tuned.

Pixagram Announces Free Account Creation for 250 New Users Daily Through 2026

Published

on

Panama City, Panama, October 15th, 2026, Chainwire

Pixagram announces free account creation for up to 250 new members daily through the end of 2026. Built on the standalone Layer-1 Pixa blockchain, Pixagram is an anti-hierarchy social network where every post, vote, and comment is recorded as a signed on-chain transaction, with no ads and no cryptocurrency purchase required to get started.

Pixagram will cover the 20 PIXA network fee for up to 250 new members daily through the end of 2026. New members can claim a free @username at Pixagram.com and join the platform’s on-chain community for creators.

► Quit Renting the Spotlight — Users can register at http://pixagram.com

An On-Chain Username and Wallet Address

Opening a Pixa chain account normally costs around 20 PIXA. Pixagram is covering this fee for up to 250 new members daily through the end of 2026.

  • Username and wallet address: Each @username serves as an on-chain wallet address, replacing a randomly generated string of characters with a recognizable handle.
  • Blockchain-based registration: Once registered on the blockchain, an @username remains associated with its on-chain record, subject to the network’s rules and technical conditions.
  • Phone verification and privacy: One-time phone verification helps limit bot abuse of the daily account offer. A public @username can separate a creator’s online identity from their legal name, although public blockchain records may limit privacy.

Not Really Anti-Social, Truly Anti-Hierarchy

Mainstream social media serves advertisers while gatekeepers decide who sees your work. Pixagram—alongside platforms like Hive and Mastodon—is a SIGMA platform built for creators who prefer agency over status games. Your posts, art, followers, and feeds live directly on-chain with nothing in between, allowing you to reach every follower automatically.

NFT Platform Storage and Artwork Permanence

On many NFT platforms, the token sits on-chain while the image lives on a cloud server or IPFS—meaning a token can easily outlive its art.

On Pixa, every artwork is stored directly on-chain inside its post as a lossless image. Compact pixel art lives permanently on the blockchain and renders up to 4K resolution as a painting, CRT filter, hexagonal shapes, or square pixels.

  • Zero upfront cost: Every new account receives a starter delegation of stake (Resource Credits fuel) to cover posting and voting from day one.
  • Build Mode Note: Direct on-chain art sales launch in 2027, so everything you publish today builds your permanent portfolio ahead of the marketplace release.

► Less Lurking. One Original Post. Start at Pixagram.com

Proof-of-Brain and Community Curation

Instead of relying on the computational process used in Proof-of-Work systems, Pixagram uses Proof-of-Brain, a mechanism that allocates rewards based on posting, commenting, and voting activity.

  • Community reward distribution: 70% of newly issued PIXA is allocated to community-voted content, with 60% distributed to authors and 40% to curators after seven days.
  • Staking and governance mechanisms: Authors can receive Pixa Power, which determines voting weight and supports governance participation, and Pixa Supra (PXS), a unit referenced by an oracle to a agnostic purchasing power index (without a fixed dollar value). Curators can also receive Pixa Power.

Censorship-Resistant by Design

Built on the Hive codebase with Steem lineage, the Pixa chain started from a clean genesis block with no airdrop and produces a block every three seconds. While an application interface can hide a post from its view, it can never erase the transaction record from the chain.

Furthermore, every artwork is checked for copies using PAPH-X (an open-source perceptual fingerprint for pixel art) and indexed by the Search V4 engine.

“The old internet wants you trapped in feed fog, renting reach from gatekeepers who track every click. Today information is king, and Pixagram operates outside that hierarchy… Don’t believe the hype. Create it.” — Matias Affolter, Co-Founder of Pixa

“The strongest rebellion is a working alternative. We’re covering the network fee for 250 new accounts a day so any creator can step into build mode at zero cost. Claim your permanent @username now—because once a handle is written to the chain, it’s gone forever.” — Mathiew Estepho, Co-Founder of Pixa

Pixagram Account Registration and Developer Resources

Pixagram offers fee coverage for up to 250 new accounts daily through the end of 2026. Eligible new members can register and claim an @username at Pixagram.com. Additional technical information is available in the developer documentation at pixa.org.

About Pixagram

Pixagram is an on-chain pixel art and blog network developed by Pixagram AG (Zug, Switzerland) and operated by Pixa Rex S.A. (Panama City, Panama).

Bergek outlines CNC manufacturing capabilities from custom design to production

Published

on

SHENZHEN BERGEK TECHNOLOGY CO., LTD. highlights its CNC machining and sheet metal manufacturing capabilities, supporting custom component development, quality inspection, and production for clients across multiple industries.

China, 15th Oct 2026 — SHENZHEN BERGEK TECHNOLOGY CO., LTD., a manufacturer specializing in computer numerical control (CNC) machining and sheet metal fabrication, has outlined its manufacturing capabilities supporting projects from computer-aided design (CAD) development through component production. The company serves customers across industries including healthcare, automotive, electronics, aviation, and industrial equipment, providing manufacturing support for both customized components and larger production requirements.

Bergek operates with ISO 9001 and ISO 13485 certifications, covering quality management systems relevant to its manufacturing operations. Its capabilities include CNC milling, CNC turning, laser cutting, and related sheet metal manufacturing processes. These technologies support the production of components, equipment enclosures, and other parts developed according to customer specifications.

Manufacturing support across project stages

The process of moving a component from a digital design to a finished part involves multiple stages, including design review, material selection, machining, fabrication, finishing, and quality inspection. Manufacturing coordination across these stages can be important for businesses developing new products or sourcing components with specific dimensional and functional requirements.

Bergek’s manufacturing operations are structured to support different project stages and production volumes. Its capabilities encompass customized component development, small-batch manufacturing, surface treatment, and larger-scale production. This structure allows the company to address varying requirements associated with product development, testing, and manufacturing scale-up.

The company reports operating a network of three subsidiaries that support different customization and production needs. Its headquarters includes a marketing center, quality inspection center, and production assembly center, alongside a supply chain system intended to coordinate manufacturing activities and related processes.

Equipment and production capabilities

Bergek reports operating 78 pieces of manufacturing equipment, including laser-cutting machinery rated above 6,000 watts and five-axis machining equipment. These technologies serve different purposes in component manufacturing.

Laser cutting is used to process sheet materials into specified shapes, while CNC milling and turning produce components through controlled material removal. Five-axis machining allows cutting tools and workpieces to move across multiple axes, supporting the production of complex geometries and components that may require machining from several directions.

The combination of these processes gives manufacturers options for handling different part designs and fabrication requirements. Depending on the project, CNC machining and sheet metal fabrication can be used separately or combined to produce components and assemblies.

For buyers managing custom manufacturing projects, coordination between design requirements, production methods, and inspection procedures can influence production planning. The availability of multiple manufacturing processes within one operational structure can also help simplify communication between different stages of a project.

Serving customers across international markets

According to company-reported figures, Bergek has accumulated experience across more than 120,000 projects and has served over 3,600 clients. Its core customer markets are primarily located in North America, Europe, and Australia.

The company works with businesses involved in product design, engineering, and manufacturing, supporting projects that require customized components rather than exclusively standardized parts. Its reported customer base spans several sectors, reflecting the range of applications for CNC machining and sheet metal fabrication.

Bergek also reports having supported clients whose designs received international recognition, including the iF Design Award. The company further states that it supplies Alibaba-certified Fortune 500 companies. These reported relationships illustrate its involvement in manufacturing projects for customers operating across international markets.

Quality management and customized production

Quality management remains an important consideration when sourcing precision-manufactured components. Specifications for dimensions, materials, surface finishes, and assembly requirements must be translated into production processes and inspection criteria that correspond with the intended application.

Bergek’s stated ISO 9001 and ISO 13485 certifications reflect its quality management framework. ISO 9001 addresses general quality management systems, while ISO 13485 is a quality management standard specifically associated with medical devices and related regulatory requirements. Certification alone does not establish that every manufactured component is suitable for every regulated application; suitability depends on the product, applicable requirements, and relevant verification procedures.

By combining machining, sheet metal fabrication, finishing coordination, and quality inspection within its manufacturing structure, Bergek supports projects with different technical and production requirements. Its operations address the needs of customers developing custom parts as well as businesses requiring repeat production.

As product development increasingly involves coordination between engineering teams and manufacturing partners, suppliers capable of working across design specifications and production stages remain part of the broader industrial manufacturing supply chain.
