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.'

Cosmochain is a complementary Company-to-Consumer platform that connects cosmetics product users and content creators to cosmetics product suppliers, including cosmetics companies, OEM/ODM manufacturers, R&D centers, and distributors. Through this platform, the Cosmochain Team aims to solve the aforementioned unmet needs of both companies and customers. All data collected from platform participants are kept confidential in this customer-centered ecosystem. Those who contribute their scarce time and attention toward producing and curating contents for others are compensated with tokens and receive pro-rata ownership of the contents they create. On the other hand, cosmetics product suppliers are able to actualize a wide variety of “on-demand” services on the platform by utilizing API that Cosmochain provides. Two different tokens and one internal virtual index make up the Cosmochain ecosystem: 1) The first token is an externally traded token called Cosmo Coin, 2) The second token as well as an index of contribution to the platform is Cosmo Power, which can be used to make payment within the platform and given out as rewards for activities, and 3) The one virtual index is called Cosmo Level. Cosmo Level, a reputation index, is designed to prevent abuse of power within the platform and can only be accumulated by actual activities and contribution. Having been assigned distinct roles within the Cosmochain platform, these three entities construct a healthy ecosystem. ● The success of the Cosmochain platform lies in the active participation of users – where customers create reliable data after trying out various cosmetics products and sharing the experience with one another on the platform. As a result, Cosmochain has designed its own transparent and fair reward system based on Steemit’s incentive model. ● The Cosmochain platform connects this user-created data to interested company participants and distributes the payment made by the company to customers as reward for use of the information. Through this reward system, Cosmochain aims to address two structural issues of social media-based platforms: 1) risk of inflation following the necessity of a long-term and great quantity of token issuance to grow the community, and 2) risk of decreasing attractiveness of contribution rewards after the inflation rate has been stabilized. ● In addition, the Cosmochain platform aims to realize an upgraded tokenization model that brings the power back to its users by redistributing the following: (i) the right to display ads in a user’s viewing space, (ii) the right to access a personally curated Marketplace, and (iii) the right to share personal data to partake in a study or survey. Simply speaking, the Cosmochain platform will go beyond simply allowing users to share onedimensional personal information. As such, Cosmochain serves the purpose of revolutionizing the cosmetics industry’s ecosystem by redistributing ownership and management authority of personal cosmetics data and contents to those in need, and through operations of transparent rewarding system for the redistribution of data.
