I've written some notes about a GNUnet paper and put it on my "http://zooko.com/reading.html";. After waiting in vain, for about an hour, for my friends to check my web page and write letters to me about decentralized incentive engineering, I lost patience and decided to send it to these lists. --Zooko An Excess-Based Economic Model for Resource Allocation in Peer-to-Peer Networks dura-link [1] v1.0.1 entry above [2] This is a reasonable stab at the problem from an engineering approach. The ideas are actually implemented, as I understand it, in GNUnet. It is completely decentralized, and they've given thought to the detailed problems: newbies, transitive operations, systemic attack resistance. It feels like exploratory work, and the author admits as much. He includes, for example, a "proof" that the attack resistance of the system as a whole is bounded by the attacker's bandwidth, but it is so specific to GNUnet's design and its assumptions that it isn't an exciting general result. These GNUnet-specific assumptions include that all traffic is request-response pairs, the requests are the only things that trigger consumption of resources, the responses are verifiable (except that this verification isn't yet implemented in the current GNUnet), and so on. Still, to his credit the author is clear that this is exploratory, and he clearly indicates his plans for future work. On a personal note, it is bittersweet to see some ideas that we implemented in Mojo Nation being reinvented here, such as the central notion of "excess-based" accounting, in which services are free when the server is idle anyway. I don't feel pride about this -- rather I feel regret that we didn't document what we did, and gratitude that the GNUnet folks are doing the world a better service by documenting their ideas. Also, of course, GNUnet is not identical to Mojo Nation, as GNUnet lacks the centralized component that Mojo Nation had. The basic approach that GNUnet takes to decentralized incentives is very like what I've been planning for Mnet v0.7. For anyone out there who is familiar with Mojo Nation, it is pretty much what you get by leaving the "KEEP_RUNNING_WHEN_TOKENSERVER_IS_DOWN" flag set and then adding some tweaks to favor the most useful of your peers. If you are interested in decentralized incentives in Mnet v0.7, you should read this paper.
