Decentralized applications running on Ethereum suffer from 2 problems: Latency in waiting for transactions to confirm and difficulty in handling more than hundreds of transactions a second. State channels are a possible elegant solution to both the latency and scalability challenges for DApps. Here, I talk to Jeff Coleman, a consultant who evangelizes the state channel approach. We talk about various themes such as: The Latency and Scalability challenges of building Ethereum DApps What are state channels and how do they work? What is needed for widespread use of state channels? The difference between Bitcoin micropayment channels and Ethereum state channels. Do check out the video for a glimpse into how DApps will solve their latency and scalability challenges and become widespread.

Distributed grid computing schemes allow donors to volunteer their desktop computer's idle resources toward scientific projects in physics, biology, and chemistry, where large amounts of parallel computing resources are necessary. Relying on software like BONIC, these networks provide features such as built-in fault tolerance and result verification. And with the proliferation of mobile and IoT, the potential for massively distributed grid networks has never been greater. Gilles Fedak, a researcher at the French computer science research body Inria, joins us to discuss a new project which aims to build a high-performance distributed cloud infrastructure marketplace. Relying on mature grid computing technologies, iExec utilizes Ethreum to organize a peer-to-peer marketplace of computing resources, allowing anyone to rent their idle resources to grid networks. If it succeeds to execute on its vision, this game-changing project could revolutionize distributed computing through cost reduction and commoditization of resources. Topics discussed in this episode: - Gilles' background as a distributed computing researcher - Distributed computing and it's applications in science and industry - The problems we see in distributed computing networks - The iExec project and its vision for a distributed computing resource marketplace - How iExec works as an Ethereum smart contract - The different components and participants of iExec - The iExec token and upcoming crowds ale - The project's business model and roadmap Links mentioned in this episode: - iEx.ec Website: http://iex.ec/ - Gilles Fedak Home Page at ENS Lyon: http://graal.ens-lyon.fr/~gfedak/ - iEx.ec White Paper: http://iex.ec/?page_id=186 - iEx.ec Crowdsale: http://crowdsale.iex.ec/ Sponsors: - Jaxx: Wallets that Unify the Blockchain Experience Across Devices - http://jaxx.io - Ledger: Smart card security for your Bitcoins - Get 10% off your first order when you use the code EPICENTER - http://ledgerwallet.com This episode is also available on : - Epicenter.tv: https://epicenter.tv/178 - YouTube: http://youtu.be/y_WrkUcNEDQ - Souncloud: http://soundcloud.com/epicenterbitcoin/eb-178 Watch or listen, Epicenter is available wherever you get your podcasts.
