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.
Blocknet (sometimes referred to as Block) is a decentralized, platform-as-a-service protocol that connects the nodes of different blockchains. As you probably know, there are hundreds, if not thousands, of blockchains that currently exist, and this number is showing no signs of slowing down its growth anytime soon. Many of these chains, though, are unable to communicate and interact with each other, creating small groups of siloed ecosystems. And, the inability of these groups to work together is holding back the entire blockchain industry. To solve this problem, Blocknet is working to make blockchains interoperable, mobile, and modular. This enables different chains to provide microservices to each other in a peer-to-peer fashion at higher security, faster speeds, and more efficient scalability than today’s current options. Blocknet is aiming to be the “Internet of Blockchains” through inter-blockchain connective services. Simply put, Blocknet enables you to develop on one blockchain, Ethereum for example, but access the functionality of other chains, like NEO. The team is building the infrastructure using three core components that work together to provide three primary services for these inter-chain decentralized applications (dapps). The XBridge, a blockchain router, is the backbone of the Blocknet platform. It’s the first peer-to-peer protocol to connect nodes on different blockchains, allowing them to communicate with one another. Using the XBridge, you’ll not only be able to perform cross-chain atomic swaps, but you’ll also be able to transfer additional data and execute smart contracts across chains. Blocknet uses a Proof-of-Stake consensus algorithm with three types of nodes to maintain the network. Service nodes collect and distribute trade fees on the platform as well as prevent spamming and DDoS attacks. To run a service node, you need to hold at least 5,000 BLOCK and keep your node computer running at all times. The Blocknet team recommends that, if you plan to run a service node, you should also run multiple full node wallets of whichever coins you want to support. This maximizes the trading fees you receive. Staking nodes confirm network transactions. When running a staking node, you’ll receive 9-14% annual returns from block rewards as well as a portion of the trading fees. There’s no minimum BLOCK amount you need to keep in your wallet to receive these, but you need to keep the wallet running at all times. There’s limited information available on the Blocknet team. Dan Metcalf and Arlyn Culwick founded Blocknet in 2014 as a fork of PIVX. According to his LinkedIn page, Metcalf was a Bitcoin developer for 5 years as well as a Senior DevOps Engineer at Philips. Outside of Blocknet, Culwick is also the PR and Media Liaison for XCurrency. Blocknet launched the service nodes on their main net in September 2017, and on March 1st, 2018, the team will release the beta version of the DEX. The project has also partnered with the 0x protocol to add ERC20 token support on the platform. Blocknet is connecting the isolated blockchain systems that currently exist to create one, cohesive ecosystem. Through the platform’s XBridge, the team is building a blockchain Internet in which you can build dapps that utilize features from several different chains. Starting with a DEX, the project has a lot on its roadmap including a service delivery system for blockchains to provide and receive payment for providing functionality to other chains. This is a complex project, but Blocknet already has the partnerships in place (0x, Poloniex) to see it through to the end. Blocknet consists of the following coins: XCurrency, Stealth, SonicScrewdriver, Fibre, Librexcoin, APEXcoin, BitSwift, XCash, UtilityCoin
