Ardor is the latest in the growing field of contenders for blockchain as a service (BaaS) providers. Ardor provides the blockchain infrastructure for businesses and institutions to leverage the strengths of blockchain technology without having to invest in developing custom blockchain solutions. Instead, Ardor offers a main chain that handles blockchain security and decentralization plus customizable child chains that come ready to use, right out of the box, for various business applications. The developers of Ardor are the same company behind the open source Ethereum’s ERC20 protocol to build on top of the Ethereum blockchain. They pay fees in Ether. To test Ardor’s capabilities and serve as an example of an operating child chain, the Ardor developers have created Ignis. Ignis will implement all of the customizable features that come from the Nxt code base. Essentially, Ignis will be a proof of concept and could be the first of many more child chains on the Ardor platform. The Ignis ICO recently raised $15 million in funding for development. In the future, Ardor child chains could be used to create equity trading platforms, digital file transfer services, private enterprise blockchain applications, and many more use cases. Ardor’s strengths are quick time to setup and wide customizability, making it a great option for companies looking to leverage blockchain without the resources to dedicate to custom development. Ardor has many architectural advantages. One of them and perhaps the most influential one is that it has been created using Java; one of the most widespread programming languages in the world today. This is definitely a step in the right direction seeing as it becomes ten times easier for a commercial application to succeed if the development language is one which most programmers can relate to.
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.'
