Project PAI is developing an open-source, blockchain-based platform designed to allow everyone to create, manage, and use their own Personal Artificial Intelligence (PAI). The PAI Blockchain Protocol (PAI blockchain) enables a decentralized AI economy where application developers can create products and services that will be beneficial to the PAI ecosystem and users can contribute their PAI data to improve and enhance the platform’s AI neural network. In addition, companies and developers can easily create their own token on top of the PAI blockchain to facilitate interaction and transaction in their own unique experiences. The focal point of all interactions on the PAI blockchain are PAIs - intelligent 3D avatars that look, talk and behave just like their human counterparts, made from the digital profiles of the user’s online behavior.
