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.'

The district0x network is a collective of decentralized and autonomous marketplaces and communities, also known as districts. These districts are built upon a decentralized and distributed open-source framework, the d0xINFRA network, which is powered by Ethereum smart contracts. The district0x network aims at creating a friction-free, virtual economy where the users will be able to make buying and selling decisions, complete transactions, and even rank their peers with just one simple click. District0x aims to develop a flexible, and free market with advanced entrepreneurial concepts. The District0x infrastructure has a very neat concept with some well-outlined features, such as the staking interface. A staking interface is put in place that allows DNT holders to have open control over the districts through an Aragon governance layer for all markets that come online. Post creation of a district, an Aragon entity will also be created that people can use to interact with this staking mechanism. After staking a user will receive voting rights in that district. Using the creation interface, one can remove central power structures from any marketplace without the additional need for development or programming skills. It can be described as the WordPress of dApps where the districts being launched are like wordpress templates and the auxiliary modules are WordPress plugins for extended functionality. While it is very difficult to buy lesser known cryptocurrencies using fiat currencies (dollars, euros) directly from crypto-exchanges, district0x or DNT can be easily purchased from various exchanges using Ethereum or Bitcoin as the base cryptocoin. Binance is one of the popular exchange platforms that can help trade Bitcoin or Ethereum for District0x. One can use various wallets like myetherwallet.com to store the district0x (DNT) coins. Coinbase, Blockchain, Exodus, Trezor Hardware Wallet are also wallets that supports district0x. District0x, differs from most coins in its underlying concept and the architecture it is built on. The concept of interconnected districts and marketplaces promises a novel structure to the modern economies. What a lot of users are missing out on is the fact that it is a staking mechanism and not just a voting token. Staking is basically the process of mining the PoS (proof of stake) coins. Early investors will be able to lock their tokens to a specific district on the network, thus being able to participate in its governance later. DNT tokens can be staked in districts, thus they not only give voting power and privileges within that district but also provide district-specific tokens depending on when the investor had started trading. For example, early investors of the PoS token will be able to make decisions about the distribution of profits among stakeholders, the intricacies of the business model etc. DNT can basically be considered as a dynamic stock in the future district0x ecosystem. By joining the district0x, the user receives district0x coins. They allow the owner to exercise the right to vote for district proposals and make decisions within certain districts. This includes, for example, voting on proposals concerning the future of a particular district or setting fees. The scope of shareholders’ rights is outlined in the bylaws and varies according to the specific scope and purpose of each district. District0x platform users can interact with the functions and services provided by each district. Users can also freely create their own districts. For example, on Ethlance, the first district in the District0x network, users can post job offers or search for new jobs.
