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.
iExec is an open-source, decentralized cloud computing platform, running on Ethereum blockchain. iExec allows decentralized applications (dApps) an on-demand access to computing resources and technologies on iExec cloud. iExec has built a blockchain network where dApps can take advantage of cost effective and high-performance resources such as servers, databases, SaaS applications, web hosting and computer farms. iExec’s native cryptocurrency — The RLC token is the primary asset used to access services in iExec infrastructure. RLC is short for “Run on Lots of Computers.” iExec is headquartered at Lyon, France. It was founded by Gilles Fedak and Haiwu He, both are serving as Chief Executive Officer and Head of Asian-Pacific Region of iExec, respectively. Oleg Lodygensky is the Chief Technical Officer. Gilles Fedak received his PhD from the University of Paris Sud in 2003, and has been working as INRIA (Inventeurs du Monde Numerique) research scientist at ENS in Lyon, France. Similarly, Haiwu completed his M.Sc. and PhD from the University of Sciences and Technologies of Lille, France. On April 19, 2017, iExec launched its token sale and raised more than $12 million in exchange for 86,999,784 RLC. In order to support dApps, smart contracts, and their platforms, iExec takes processing-intensive computations off-chain so as to keep a blockchain’s on-chain functions running smoothly. To do this, iExec makes use of XtremWeb-HEP, an open-sourced Desktop Grid Software. Desktop Grid computing (also known as Volunteer Computing) pools unused computing resources to be used by applications and platforms, and according to iExec’s whitepaper, XtremWeb-HEP “implements all the needed features” to make this possible on a global scale, including “fault-tolerance, multi-applications, multi-users, hybrid public/private infrastructure, deployment of virtual images, data management, security and accountability, and many more.” Essentially, with this software, dApps can utilize any computing resource in the iExec framework to run their programs. In their whitepaper, the iExec team lays out the project’s competitive landscape and explains these competitors in relation to iExec. They’re quick to note that decentralized cloud storage providers like Filecoin, Storj, and Siacoin are not direct competitors, and it’s easy to see why. While iExec could theoretically take a step in this direction as it matures, it’s not a storage platform; it’s a computing platform. This does put it in competition with other decentralized computing protocols like Golem and SONM. Both of these, however, are taking aim at a different animal. Essentially, they’re both building a decentralized supercomputer on blockchain technology, while iExec is targeting dApp development and sustainability. Both look towards a future of a blockchain-powered, decentralized internet, but their functions, while sometimes similar, are more complementary than conflicting.
