"The Compute Power Market (CPM) Project uses economics approach in managing computational resource consumers and provides across the world in peer-to-peer computing style. It allows application users to access computing power with ease and simplicity of accessing electric power form a wall socket. It even allows to choose computing power/resource providers that offer cost-effective service on demand. Thus creating a competitive market approach to service oriented P2P computing."
Solving problems like compute this for me, within 2 hours for $5 dollars. Sounds a lot like smart contracts. The economy grid page has some of the latest snippets of news about grid computing and a thesis on using economics for resource management in computing. See my previous postings too.
