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.'

Enigma is a crypto platform that’s trying to solve the problem of privacy on the blockchain by giving them access to much-needed storage, privacy, and scalability. Enigma wants to extend Ethereum Smart Contracts by introducing secret contracts, a brand of smart contract that gives users an element of privacy that’s not intrinsic to current blockchain protocols. These contracts operate off-chain, meaning the execution of the Smart Contract doesn’t occur on the Ethereum blockchain itself. This is how the Enigma protocol works: it breaks up the Smart Contract and any related data into pieces, encrypts those pieces, and distributes them redundantly among Enigma nodes. Enigma has a protocol level. The Enigma privacy protocol allows for decentralized computation of sensitive data. It has a platform layer too. On this protocol, dozens of platforms such as data marketplaces and AI exchanges can be built. In its application layer, it enables thousands of truly decentralized apps that require private computation and secure data.Its first application is catalyst. Catalyst is the first application to be built on the Enigma protocol, already active with tens of thousands of users. Catalyst is a revolutionary platform for data-driven cryptoasset investing and research, built for professional crypto traders. Enigma has a team of MIT graduates, and they’ve been working diligently to ensure Enigma’s success. Guy Zyskind, Enigma’s CEO and cofounder, helped start the project while he was still a student at MIT. He has more than a decade of software development experience with an M.S. from MIT. Sandy Pentland, a well known MIT data scientist who gained fame for his work in data-mining social interactions, is Zyskind and Nathan’s adviser on Enigma. With other advisors such as Alex Pentland, who sits on the Advisory Boards for Google and Nissan, CEO of Abra, Bill Barhydt and director of MIT media lab, Prof. Alex Pentland, it is hard to difficult a fault in the team.
