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.'

LBRY (pronounced “Library”) is a decentralized digital content distribution protocol and a marketplace for the same. It supports a variety of content which includes but not limited to videos, songs, ebooks, etc. LBRY uses blockchain at its core, which enables content to only be controlled by its author/ publisher, not by any third party, effectively eliminating issues like censorship and copyright strikes. Since the code of the LBRY project is open-source, developers can create their own decentralized apps (dApps). Content creators can use these apps to upload their content on the LBRY network and monetize it by setting a fee. LBRY credits or simply LBC is the cryptocurrency created by the LBRY network to fuel its entire digital content market. The LBC coin is required by consumers to access the monetized content on LBRY network. The LBRY platform also allows LBC mining by giving block rewards. Jeremy Kauffman co-founded LBRY Inc. with the vision of a decentralized global content hub, controlled and owned by no one. Currently, Jeremy is the chief executive officer of LBRY Inc. Before working on the LBRY project, Jeremy founded TopScore, a million dollars event and activity registrations startup. There are three other co-founders who serves on different positions in LRBY Inc: Alex Grintsvayg (Chief Technical Officer), Josh Finer (Director of Operations and Analytics), and Jack Robison (Protocol Developer). LBRY provides its own official app, which can be used to store LBC. The LBRY app is available for multiple operating systems such as Windows, MacOS, and Linux. Android and iOS versions are still in development. Other than its official LBRY wallet, users can opt for the Coinomi mobile wallet, which is recommended by LBRY. LBC can only be obtained through exchange. Users can also take advantage of LBC mining and various rewards given in LBC coin by LBRY network to its users. Although the concept behind the LBRY network has a lot of potential for growth, it faces competition directly against the entertainment giants such as YouTube and Netflix, and some of these platforms have been around for more than a decade.
