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.
The Cosmos network consists of many independent, parallel blockchains, called zones, each powered by classical Byzantine fault-tolerant (BFT) consensus protocols like Tendermint (already used by platforms like ErisDB). Some zones act as hubs with respect to other zones, allowing many zones to interoperate through a shared hub. The architecture is a more general application of the Bitcoin sidechains concept, using classic BFT and Proof-of-Stake algorithms, instead of Proof-of-Work.Cosmos can interoperate with multiple other applications and cryptocurrencies, something other blockchains can’t do well. By creating a new zone, you can plug any blockchain system into the Cosmos hub and pass tokens back and forth between those zones, without the need for an intermediary. While the Cosmos Hub is a multi-asset distributed ledger, there is a special native token called the atom. Atoms have three use cases: as a spam-prevention mechanism, as staking tokens, and as a voting mechanism in governance. As a spam prevention mechanism, Atoms are used to pay fees. The fee may be proportional to the amount of computation required by the transaction, similar to Ethereum’s concept of “gas”. Fee distribution is done in-protocol and a protocol specification is described here. As staking tokens, Atoms can be “bonded” in order to earn block rewards. The economic security of the Cosmos Hub is a function of the amount of Atoms staked. The more Atoms that are collateralized, the more “skin” there is at stake and the higher the cost of attacking the network. Thus, the more Atoms there are bonded, the greater the economic security of the network. Atom holders may govern the Cosmos Hub by voting on proposals with their staked Atoms.
