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.'

TrueUSD provides its token holders regular attestations of escrowed balances, full collateral, and also the legal protection against misappropriating underlying USD. The team believes that TrueUSD will be able to come up with the stable trading instrument for the traders of cryptocurrency that has been long-awaited. This will allow the businesses and consumers to use the digital currency as a medium of an exchange. The goal of the TrueUSD team was to build a coin that is stable and which can be used and trusted by them too. TrustToken is a platform that creates the tokens backed by assets that can easily be purchased and sold all around the world. The first asset token of TrustToken is TrueUSD, which is a stable coin and can be redeemed 1-for-1 for US dollars. TrustToken have partnered with registered fiduciaries and banks for holding the funds securely backed by TrueUSD tokens. To increase the amount of security, fiduciaries, and banks directly handle all the funds. Escrowed funds do not give access to the TrueUSD system. TrueUSD works with various trust companies which already manage around billions of dollars. Just pass an AML/KYC check, send USD to a trust company with an agreement of escrow. When the funds get verified, their API tells the smart contract of TUSD to mint an equal amount of TUSD to your public Ethereum address. The USD funds are regularly verified in scheduled attestations by a very much trusted auditing firm. USD funds are kept safely in a third party account, that is escrow accounts, wherein TrustToken does not hold any direct access to the funds and cannot abscond with them even if they wish to. The token burning and minting system makes sure that every TUSD token is backed by 1 USD. A mandatory check of AML/KYC makes sure that TUSD keeps shady people away from the entire project. TUSD makes faster transactions in low transaction fees. Even though TUSD is a unique offering, it is most likely overshadowed by its bigger competitors - Tether. While TUSD arguably offers more security and features, it may be losing the marketing battle. This is not to say that the situation will remain the same. With more crypto investors joining the market every day, the good times for TUSD may be on their way.
