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.
Bitcoin Diamond (BCD) is a fork of Bitcoin that occurs at the predetermined height of block 495,866 and therewith a new chain will be generated as the BCD. Bitcoin Diamond miners will begin creating blocks with a new proof-of-work algorithm, and will consecutively develop and enhance the protection for account transfer and privacy based on original features of BTC. This will cause a bifurcation of the Bitcoin blockchain. The original Bitcoin blockchain will continue unaltered, but a new branch of the blockchain will split off from the original chain. It shares the same transaction history with Bitcoin until it starts branching and coming into a unique block from which it diverges. As a result of this process, a new cryptocurrency was created which we call “Bitcoin Diamond”. Bitcoin Diamond coin could win over a lot of Bitcoin users with its faster transaction times, lower fees and easier access to new users. Bitcoin is a hugely popular coin but it can be quite difficult to use! Many critics of Bitcoin argue that the coin won’t be a valid replacement for normal money until users can make small purchases; quickly and easily. A network offering these features will also appeal to small businesses dealing in low priced, high-volume goods like coffee or fast food. However, in my opinion the price of Bitcoin Diamond will have to be more stable before it attracts any big-brand clients like Starbucks or McDonalds. One of the main safety features of blockchain technology is encryption. Private personal information is hidden using computer code. Some critics of Bitcoin think that not enough user information is encrypted. For example, all transactions and their amounts can be seen by anyone using the Bitcoin network. This can make tracing the real identities of users fairly easy for governments and other organizations. The team behind Bitcoin Diamond wanted to encrypt more user information. However, they have recently decided not to add more privacy features to BCD. They feel that governments will soon start passing laws that stop cryptocurrencies from hiding user data. In a statement published on Medium, the team noted Japan and Russia as examples of this trend. Bitcoin Diamond is processing much larger blocks than Bitcoin in the same amount of time. Larger blocks mean more transactions and a quicker average transaction time. Bitcoin Diamond makes it easy to mine BCD with less powerful computers. GPU mining allows more users to get involved in supporting the network and this can only be a good thing. Bitcoin is the world’s top cryptocurrency but it’s still quite difficult to use. Diamond coin’s high transaction speeds and low price could make it perfect for buying and selling small and inexpensive products like coffee or bus tickets.
