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!
