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.'

Paxos Standard (PAX) was created by Paxos, a financial technology company on a mission to modernize finance by mobilizing assets at the speed of the internet. Paxos was the first virtual currency company to receive a charter from the New York State Department of Financial Services. As a chartered limited purpose trust company with fiduciary powers under the Banking Law, Paxos is able to offer regulated services in the crypto-asset and virtual commodities space. The Paxos team comes from a wide variety of backgrounds with a diverse array of experiences ranging from Wall Street to Silicon Valley. It’s led by CEO and co-founder Charles Cascarilla, who has spent his career as a customer, analyst, investor and now creator of financial technology. Paxos describes itself as “the first regulated Trust company with blockchain expertise”, and it is using that expertise to create a modern settlement solution that can eliminate risk and simplify settlements. What many people may not know about Paxos is that it was actually founded in 2012 as Paxos Trust Company, and that for most of its life it ran the cryptocurrency exchange itBit, which is still operates. The creation of Paxos was a pivot from an exchange platform to a company focused on creating a modern settlement platform using blockchain technology. Paxos has become the most widely adopted cryptocurrency in the fastest time frame, with support from over 20 exchanges and OTC desks in the first five weeks of its existence. It’s been picked up and listed by six of the top ten cryptocurrency exchanges, Binance, OKEx, Gate.io, ZB, KuCoin and DigiFinex. These exchanges are offering PAX as an alternative to the controversial Tether. Unlike the controversy surrounding the people who control Tether, there is no such obscurity when it comes to the people behind Paxos. The CEO and co-founder is Charles Cascarilla. He has over 15 years in financial services and has co-founded Cedar Hill asset management back in 2005. He has also worked and Bank of America and Goldman Sachs prior to that. The Paxos Standard (PAX) is the first digital asset to be issued by a financial institution and to be fully secured by the U.S. dollar. While other similar stablecoins have existed, there has been no proof of full U.S. dollar reserves, nor have these earlier assets been issued by a financial institution. The Paxos team has been fairly clear in declaring the different base that PAX is working from.
