ChainLink is a decentralized oracle service, the first of its kind. When Ethereum went live in 2015, it revolutionized what blockchain could bring to enterprise solution and traditional business. Blockchain was no longer just a medium for new age financial transaction, confined to Bitcoin’s potential to disrupt traditional currency exchange. With Ethereum powered smart contracts, Vitalik Buterin opened up a Pandora’s Box of use cases for blockchain technology. Problem is, per their design, smart contracts can only manage data on the blockchain. Their potential, the ability to provide tamperproof, decentralized applications for uses the world over, is still largely untapped, as many of the smart contract programs built on Ethereum lack a bridge to the real world industries they’re trying to improve. ChainLink’s first component consists of on-chain contracts deployed on Ethereum’s blockchain. These oracle contracts process the data requests of users looking to take advantage of the network’s oracle services. If a user or entity wants access to off-chain data, they submit a user contract (or requesting contract) to ChainLink’s network, and the blockchain processes these requests into their own contracts. These contracts are responsible for matching the requesting contract up with the appropriate oracles. The contracts include a reputation contract, an order-matching contract, and an aggregating contract. The first of these, the reputation contract, is exactly as it sounds: it checks an oracle provider’s track record to verify its integrity. In turn, the order-matching contract logs the user contract’s service level agreement on the network and collects bids from responsible oracle providers. Finally, the aggregating contract accumulates the collective data of the chosen oracles and balances them to find the most accurate result. Unfortunately, the ChainLink team does not offer a roadmap, but a testnet of ChainLink’s services should come sometime within Q1 of 2018. Generally, the project’s general lack of marketing and concrete updates have frustrated community members in the past. Sergey Nazarov, the project’s CEO, is known for a quiet community presence that favors of behind-the-scenes work on ChainLink. The team may not hype their project much, but for what it’s worth, they sacrifice brand marketing in favor of product development–and some community members find this focus to be refreshing. For instance, they’ve established an oracle with Swift Bank, and have a few quiet partnerships with zepplin_os and Request Network. Chainlink has the potential to connect smart contracts with the outside world. It may allow parties to smart contracts to be able to receive external inputs that prove performance and create payment outputs that end users want to receive, such as bank payments. This has the potential to allow smart contract to mimic the vast majority of financial agreements currently available in the market. With the ChainLink Network, anyone can securely provide smart contracts with access to key external data and any other API capabilities, in exchange for financial reward. Although it remains to be seen how the incentive system will operate, there is potential for rewards similar to those available for crypto miners to be available to Node Operators that provide useful data to the Chainlink network.'

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.
