Project PAI Announces Technical Progress, Catena NFT Platform is Coming Soon!

The annual PAI Day on March 14, 2021 came as usual. To thank PAI enthusiasts for their continued support, Project PAI core developers launched an AMA campaign through the community and gave millions of airdrop rewards back to PAI contributors and community members. The following are the selected AMA questions, enjoy:
Q: Why do I feel like the Project PAI Team has been quiet for a while? What has been done by Project PAI in the past year? What is the recent work plan done by Project PAI? Will there be plans to support DeFi and NFT?
A: In October 2020, PAI switched from a conventional PoW-style blockchain to a new PoW/PoS Hybrid Consensus model. The current primary focus of the PAI Core Contributors is to ensure that the PAI blockchain is stable and reliable, so that PAI Hybrid Consensus can thrive as a fully decentralized network In addition to technical contributions, this includes acquiring more network participants to further decentralize the blockchain, and providing support to the Catena NFT project, which will soon support PAI Coins and enable Project PAI ecosystem.
The team is following up on the trends in the Defi world, and will participate in the innovation of the Defi world by cooperating with other projects. In addition, we are studying possible technical solutions to enable cross-chain features for PAI coins (such as Ethereum, Heco, BSC, etc.), which enables PAI coins to be used in some Defi applications in the future.
Q: When will Project PAI’s NFT platform go online? Compared with other NFT trading platforms on the market (such as OpenSea, Rariable, etc.), what are the advantages?
A: The Catena NFT platform based on the PAI blockchain is currently available on catenaart.com and is currently in the public prototype testing stage, allowing people to upload their own arts on the platform. The core contributors of PAI sincerely welcome you to participate in the prototype test of the product and provide any suggestions or feedback. After completing the prototype test, we will further optimize the product and improve the user experience design based on the feedback. The first official version is expected to be released in Q2 of 2021.
Cartena NFT is a completely decentralized art trading platform based on the PAI blockchain. The main features of Cartena NFT are:
1. Fully decentralized NFT trading market, connecting on-chain and off-chain: On Cartena NFT platform, you not only trade NFT, but also obtain its NFT on the PAI blockchain while trading real arts, which is both on-chain and off-chain.
2. Support multiple payment channels: Catena NFT platform will support PAI coins, mainstream cryptocurrencies (BTC, ETH, etc.) and credit card payments.
3. The built-in encrypted communication system allows the buyer and seller to communicate during the NFT transactions to ensure the progress of each transaction.
4. The identity authentication system based on PAI PASS ensures the authenticity of both parties in the market. Users can track each step of each transaction on the PAI blockchain.
Welcome to participate in the prototype test of Cartena NFT platform and give feedback on the PAI forum.

Q: What is PAI’s PoUW? When is it planned to launch?
A: Project PAI’s Proof of Useful Work (PoUW, Proof of Useful Work) is a research project designed to enable miners to perform machine learning calculations while verifying PAI currency transactions. The purpose of PoUW is to use AI calculations to replace traditional PoW hashing operations, so that the computing power on the blockchain can be used for actual AI applications, making these computing powers “useful”. In the future, these computing powers can not only be used for machine learning training, but can also be extended to general-purpose on-chain computing, such as on-chain data analysis, cryptographic-based on-chain privacy computing (such as zero-knowledge proof, secure multi-party computation), etc.
PoUW is a passionate research-oriented project, completed by multiple core contributors to Project PAI. The PoUW testnet was originally planned to be launched in the second half of 2021. Due to the cutting-edge and uncertainty of technical research and other product plans of Project PAI, we will try our best to ensure the launch of the PoUW testnet.

Q: The current applications and use cases for PAI seem unclear to me. What does PAI’s economy offer compared to other chains that focus on use cases like finance?
A: Referencing the original vision (tech white paper), the PAI Blockchain fundamentally comprises three modules: Authentication layer, Blockchain layer, and Data layer:
1.The Authentication layer controls relationships that exist in the PAI ecosystem.
2.The Blockchain layer houses a record of network transactions as well as protocols for peer-to-peer engagement.
3.The Data layer indexes encrypted data, peer-to-peer, with hashed references.
Theoretically, any applications or use cases which require one or a combination of authentication services, transactional services, or data storage and sharing services (which, as you can imagine, is quite a lot) can leverage PAI blockchain technology. Currently, the most concrete example of a PAI use case is the NFT art platform, Catena, which is accessible at catenaart.com.
We will release other questions in the PAI weekly newsletter one by one. Welcome to pay attention to the wechat public account of Project PAI and PAI Fans, and keep track of the latest progress of the project. Thank you for your continued support!

Hotel Blacklist Launches New Accommodation Industry Risk Assessment Tool
New York, United States, October 7th, 2026, FinanceWire
Hotel Blacklist has launched a new free online resource designed to help hotels and accommodation providers identify high-risk guests and prevent potential financial losses, property damage, fraud, and disruptive behaviour. The service, available at hotelblacklist.org, provides a shared guest-risk database that supports the hospitality industry’s existing “Do Not Rent” (DNR) practices.
One of the greatest challenges of the travel accommodation industry is accepting anonymous reservations from OTA’s with no risk assessment or public record of who is about to enter their hotel asset.
OTA’s are Online Travel Agencies that provide commission-based “blind/anonymous” reservations to accommodation providers. The identity of these OTA hotel room reservations is often unverified and provides no cautions or public record as to the character of the individual/s or Verification of Identity (VOI).
OTA travel websites offer a one-sided review platform with guests providing comments and ratings of their accommodation experiences. The biased conundrum is that the accommodation industry has not been provided a similar tool to review or rate a guest’s conduct during a stay at their hotel.
The horror stories of disruptive or illegal activities that hotel owners have been subjected to are numerous and, unfortunately, could have been prevented with no free resources available to conduct reservation due diligence and a risk assessment.
The Hotel Blacklist is a public register of individuals reported by all forms of accommodation providers and is a name-and-shame register providing hotel managers the resource and ability to search and identify Hotel Blacklist individuals and the choice to block – reject – refuse the reservation at their venue.
“Our hotel users have been subjected to assaults, fraud, theft, property damage and abusive behaviour towards staff. The 0.01% of these undesirable individuals have had no recourse, no accountability and no public record… until now,” says Mr Simon Rens of Hotel Blacklist.
Launched in October 2026, the website hotelblacklist.org has, in days, registered 100s of new hotel users located in Australia, the USA and Europe.
He adds: “Our free service is intended to be an industry provocateur and bring accountability to repeat offenders that have caused harm to the hotel industry, they can now be identified and their future reservations refused”
Whilst hotel chains and individual accommodation providers maintain a DNR “Do Not Rent list, or internal private database, they are not open source or shared with the other 700,000 + hotels worldwide, allowing repeat offenders to continue to attack and disrespect the next hotel, unaware of the individual’s past behaviour.
About Hotel Blacklist
Launched in October 2026, the website hotelblacklist.org is a new free website [ search engine tool ] and is solely for the benefit of the global Hotel and accommodation industry and provides a useful online archive for hotels to conduct due diligence, undertake a general guest risk assessment, detect fraud, and flag high-risk bookings before accepting a reservation.

OGRD Alliance Advances PLPC Multi-Asset Platform Following APHELAR Milestone, Expanding Licensing and Strategic Capital Frameworks
DUBAI, UAE, October 6th, 2026, FinanceWire
Microdomain Science connects differentiated assets across personalized immuno-oncology, acellular biotechnology, MedTech and precision nutrition as OGRD Alliance expands international market access, asset-specific licensing, commercialization and strategic-capital initiatives.
OGRD Alliance L.L.C-FZ announced a new phase in the international development of PLPC Platform following the public listing with Singapore’s Health Sciences Authority (HSA) of the APHELAR Family as Class A medical devices, with OGRD Alliance identified as Product Owner.
The milestone adds a defined MedTech pathway to PLPC Platform, extending a broader multi-asset architecture designed to support distinct scientific, regulatory and commercial development routes.
Singapore provides an important regulatory reference. In 2026, HSA achieved World Health Organization Maturity Level 4 (ML4) for medical-device regulation, the highest level under the applicable WHO benchmarking framework. For OGRD Alliance, the Singapore milestone establishes a concrete regulatory and documentary reference from which urisdiction-specific classification and market-access strategies can be developed internationally.
APHELAR is manufactured in Singapore by Smicna Pte Ltd., while OGRD Alliance remains Product Owner. Its Free Sale Certificate provides additional documentary support for international expansion.
From Microdomain Science to Differentiated Assets
PLPC Platform is developed from Microdomain Science, a framework focused on the spatial organization of membranes, interfaces and molecular microdomains within biological systems.
The platform translates this scientific foundation into distinct assets as a: ONCOVIX as a personalized immuno-oncology guidance and support program; PLPC-DB as an acellular biotechnology matrix; APHELAR as a microstructured MedTech platform; and ABIMPROSYC as a precision-nutrition platform.
Within APHELAR, Microdomain Interface Priming describes the physical organization of a localized and microstructured skin interface, consistent with the device’s primarily physical and structural intended purpose.
“PLPC Platform is designed to translate a common scientific architecture into differentiated assets capable of advancing through distinct regulatory and commercial pathways,” said Dr. Ramón Gutiérrez-Sandoval, oncologic pathologist and CSO of OGRD Alliance. “APHELAR now provides a tangible MedTech reference around which manufacturing, licensing and international expansion can be structured.”
Scalability, Licensing and Strategic Capital
The APHELAR milestone provides OGRD Alliance with a defined regulatory and manufacturing reference that can support the preparation of market-specific dossiers and market-access strategies for additional jurisdictions.
ABIMPROSYC, OGRD Alliance’s precision-nutrition platform, adds a complementary route to scale through a modular product architecture designed for territorial distribution, commercial licensing and, where appropriate, transfer of formulation or know-how for local manufacturing.
Together, APHELAR and ABIMPROSYC illustrate two distinct translation models within PLPC Platform: regulatory pathway scalability through MedTech and commercial portability through precision nutraceuticals.
In parallel, from its base in the United Arab Emirates, OGRD Alliance is expanding its international network of relationships with organizations specializing in regulatory affairs, market access, technology transfer, licensing, manufacturing, commercialization, transaction structuring and strategic capital across global markets.
PLPC’s multi-asset architecture enables licensing, partnerships and strategic-capital structures to be organized independently by asset, territory and development stage, without concentrating the platform in a single technology or jurisdiction.
About OGRD Alliance
OGRD Alliance L.L.C-FZ, based in the United Arab Emirates, develops PLPC Platform as a translational architecture connecting science, productization, regulatory access, technology transfer and international licensing, including asset- and territory-specific NewCo structures designed to support focused development, strategic capital and commercialization.
Scientific and Regulatory Scope: This release presents scientific, corporate and financial information of international scope. Class A classification refers specifically to APHELAR under Singapore’s HSA framework. Each asset is subject to the classification, indications, claims and regulatory requirements confirmed for each applicable jurisdiction, without extrapolation to other markets.
