Zen is a decentralized financial platform, built from scratch with the goal of providing people with a secure, scalable and useful infrastructure for creating their own financial instruments, and trading them directly without intermediaries.The Zen blockchain is secured by multiple proof-of-work algorithms, with token-holder voting on the balance between them. Multi-hash mining creates robust incentives for miners to deliver efficient, reliable security.Zen smart contracts are written and secured by a subset of the F* functional programming language, allowing users to: A) Prove the amount of resources a contract will consume and provide the necessary fees for running the contract to miners, removing the need for a “gas” based system.B) Prove their contracts meet a given specification, meaning they can prove the contract will definitely do (or not do) something given a specific set of parameters.The Zen platform comes with a built-in solution for oracles, which provide contracts with useful real world data.Finally, Zen is integrated with the Bitcoin blockchain, allowing contracts to observe and respond to native bitcoin transactions
Project PAI is an open-source blockchain project developing the world's first blockchain-based platform for intelligent 3D AI avatars. Personal AI (PAI) looks, talks and behaves like the individual user and, when secured and authenticated on the blockchain, allows for unprecedented customization, utility and personal data control. With communities worldwide and adopters including leading U.S. AI company ObEN Inc., Project PAI is rapidly advancing its vision of allowing everyone in the world to participate in the new global humanistic AI economy. Project PAI's independent blockchain platform is intended to allow users to create, own and manage their digital identity and the associated data, letting users participate in a new global humanistic AI economy where they are the owners of their own digital identity and data. The listing on HBUS marks another step in Project PAI's growth throughout the U.S. and global market. Project PAI's vision is to create a platform where everyone can create their own Personal AI, intelligent digital avatars that look, sound and behave like them. With PAI, users can have more personalized digital experiences, including using their PAI for social media content or interacting with the PAI of their doctors, teachers or even their favorite celebrities across a number of applications in retail, entertainment, travel and more. The core technology for the avatars is powered by Project PAI early-adopter ObEN, a leading artificial intelligence company based in Los Angeles, California. PAIs are secured and authenticated on the Project PAI blockchain. The intention is to always allow the user to be the owner of their own data and if they choose to contribute that data to improve applications or AI algorithms on the PAI blockchain, they can be compensated for their efforts in PAI Coin. In addition, as an open-source public blockchain, companies and developers can create their own apps and tokens on the PAI blockchain to build more interactions for the Project PAI community. Already this year, Project PAI has launched both its mainnet and github. A third-party-developed digital wallet for PAI Coin, called PAI Up, is also available globally on both iOS and Android. The project has recently expanded into the Southeast Asia, U.K. and European markets, following solid presence in China, Japan, Korea and the U.S.
