backfeed

The "backfeed" protocol is a public objective non-economic reputation system

It issues tokens to compensate "contributions" to "communities" as a function of "evaluations" made by reputed community members.

The token issuance mechanism is resistant to Sybil attack because a majority of reputation is required to participate for issuance to occur.

Reputation is (optionally) redistributed between evaluators based on their ability to predict future evaluations.

The reputation distribution mechanism is resistant to Sybil attacks so long as Sybil cannot predict the evaluations of non-Sybil commmunity members.

This code is pre-alpha - the contract does not compile and is incomplete.

Flaw with example from TechnicalSummary

There seems to be a flaw with the example at the end of the TechnicalSummary document:

From Figure 2 it appears that the last 5 users will lose more reputation in voting (even when fully in line with the DC) than they will gain by the time the last user votes. Since they will never be able to regain the cost for voting, it's rational to say that they wouldn't vote. Knowing this, user 5 would also not vote, as he too will be unable to regain the cost of voting if no other user votes after him. The same reasoning extends all the way to user 1, and therefore it is not rational that any of them votes.

Is this an issue with the parameter setup of that example, or a general flaw of the voting process?

Backfeed protocol

Hey - just read through the backfeed description.

With some other people I was brainstorming about different mechanisms for assigning reputation to each other and we did not come to a satisfying solution yet.

We basically - no matter what - always ended up in one of two scenarios.

1. Someone who earned reputation in the past, can passively free ride forever on the benefit that come with certain earned reputation
2. Or, if there are certain rules about how other can make people loose reputation, then certain people, by being very creative in using those rules could basically make reputation meaningless.
   • We had something similar to backfeed in mind and concluded, that once one or more creative players manage to earn the majority of reputation, they can basically "design" other peoples reputation however they like and nobody can do anything about it.

How do you at Backfeed think of addressing this issue that once reputation gets concentrated, it stays concetrated?

Or - in case i missed something about the backfeed protocol, I'd like to learn about what prevents the concentration :-)
