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.'

Power Ledger (POWR) is an Australian blockchain-based cryptocurrency and energy trading platform that allows for decentralized selling and buying of renewable energy. The platform provides consumers with access to a variety of energy markets around the globe and is meant to be scalable to various energy infrastructures and regulations. The market is based on a dual-token ecosystem operating on two blockchain layers, POWR and Sparkz. POWR tokens allow consumers and hosts providing energy to interface with the ecosystem and are protected through Smart Bond technology. POWR tokens can be converted into Sparkz tokens, which can be used for frictionless transactions in the energy exchange market. The initial coin offering for POWR tokens became the largest crowd funding project in Australia and the 14th highest in the world. Power Ledger’s team has immense expertise in both blockchain and electricity markets. They’re comprised of six Board of Directors in addition to over ten full time-team members. Power Leger’s five co-founders make up five of the six Board of Director seats of the company. The sixth board seat belongs to venture capitalist Bill Tai. Receiving his MBA from Harvard, Yai is a world-renowned venture capitalist. Tai’s experience is quite extensive; he is currently the Chairman of Treasure Data and also a Board Member of Bitfury and Boxer. Power Ledger’s POWR Presale sold out in just three days and raised over thirteen million dollars (AUD) in exchange for 190,000,000 tokens. After the presale, Power Ledger held an ICO to sell the remaining 160,000,000 POWR tokens allocated to Token Generation Event. After both rounds, funds raised totaled thirty-four million dollars (AUD). In addition to money raised from its presale and ICO, the Australian Government also awarded Power ledger a grant for 8 million dollars (AUD) to develop its technology and concept further. (Australia has one of the highest costs of electricity in the world and thus has a large stake in the overall success the company). Power Ledger provides a blockchain-based marketplace that can truly change the world. Taking power away from large energy companies, Power Ledger gives local communities the ability to sell their excess solar power to neighbors. Power Ledger has created an energy distribution and tracking platform that allows consumers buy carbonless, sustainable energy at lower prices than what’s offered by traditional electric companies. Power Ledger has plans to expand its operations to three continents worldwide and has amassed an army of powerful strategic partners to help achieve its goals. With the planned release of multiple applications for its platform in the immediate future, the project has positioned itself to disrupt multiple energy markets throughout the world creating a bright future for all participants involved in this green revolution.
