I describe the design of NooShare, a decentralised ledger similar to
Bitcoin with the novel feature that its proofs of work are iterations
of essentially arbitrary Markov-Chain Monte-Carlo (MCMC) chains, the
scheduling of which can be purchased using the currency itself. It is
a novel economic basis for sharing fallow computational resources.
I've given serious thought to this problem, but I am by no means an expert on any aspect of it, and I welcome all critical feedback on all aspects of it.
