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.'

Loopring is an open protocol for building decentralized exchanges. Loopring has quickly gained visibility as one of the decentralized exchange options that’s making progress on trading across multiple blockchains. Loopring’s solution utilizes ring transactions and order matching to facilitate asset exchanges. Essentially, it aggregates the order books of other exchanges. This allows any exchange, decentralized or centralized, to utilize Loopring’s protocol to match orders. Part of providing an open protocol is remaining blockchain agnostic. Hence, the first Loopring token (LRC) was launched on Ethereum, but it also plans to launch Loopring NEO (LRN) and Loopring QTUM (LRQ). The plans to launch Loopring NEO are coming along. The distribution of the new tokens, LRN, has already begun. Essentially, the token distribution involves two phases: an investor sale and an airdrop. This guide will look at both phases, how to buy LRN, and what to expect from Loopring NEO. The big selling point of Loopring’s exchange solution is you never have to deposit funds to Loopring. With most exchanges, even other decentralized exchanges, you still have to transfer funds to their wallets. On Loopring, you can keep your funds in your own private wallet when trading. Of course, that creates a challenge for Loopring because the exchange no longer controls the wallet and that means smart contracts need to do the work of verifying that transactions are legitimate and confirmed. When a trade occurs, it happens user to user, with no middleman. Loopring finds the match and coordinates the terms of the trade, but it never controls the assets. Loopring is one of the first projects to attempt launching across multiple blockchain ecosystems. This experiment is interesting and exciting. It also has the potential to be lucrative if Loopring continues to increase in value.
