Faircoin:  Blockchain based cryptocurrency with proof of cooperation

(and the growing coop ecosystem around it...)

This is the last document explaining the tech.

It will be launched as a upgrade of faircoin, in few weeks.

Interesting. thanks Ksenia.

It helps me question those different mining approaches.

I also find trustlines interesting. Which indeed seems to have a lot of parallels with the original ripple approach, but on blockchain ...

Faircoin is really looks like a permissioned chain to me, where only a certified nodes have a permission to mine? Bitcoin wastes a lot of energy, but the beauty of it, that I do not have to trust the miners. Cryptoeconomics are about arsehole network theory. They can be rational arseholes but they still maintain the system, I rely on their greed, not their honesty. 

Amongst systems that do require trust I prefer Trustlines. I think they are smart and building something quite cool. To be completely honest I think faircoin is pretty lame. I don't know, may be they're cool, but I don't like it. I think the dev picked a good name to address people who are concerned about PoW being wasteful. 

Proof of movement is something that this guy atan was working on for a while to build some sort of a decntralised uber. I think the project is dead now. Proof of movement way I understand it is really a reputation system not a concensus algo.
