This has been tried numerous times, and it either ends up with gargantuan amounts of blockchain bloat and/or a blockchain full of links to illicit content - hence my comments about the voting mechanism... In order for a bad actor to get dodgy data into the blockchain, they'd have to 51% the network... This would be greatly reduced if we offer staking, as we don't even need miners by that point.

I think this is really leaning towards PoS being the only sensible model, and I am distinctly intrigued by FLT's PoT. Here's the recently released v2 whitepaper by the way - the links on their ANN are broken at the moment: http://www.fluttercoin.us/wp-content/uploads/2014/06/proof-of-transaction-v2-r.pdf

Perhaps a PoT transaction (or "tip") could be thought of as a vote of some kind?


I like it...
