This is probably the most significant change to how donuts would work that has been on my for a while. Essentially the proposal is to designate users above a karma threshold as qualified members (or established or trusted or some better term).

While the qualified member designation could be leveraged in a number of situations, such as auth for proposing polls, the principle reason would be to alter the distribution model such that only content votes from these users counted towards karma for distribution purposes.

Content-voting based distribution is vulnerable to manipulation and brigading. It is particularly weak when these content-votes can come from any account. The qualified member designation is not a full, sybil-resistant solution, but seeks to be a sufficient measure of defense and deterrence against attacks on community governance by the illegitimate collection of karma over time.

Content voting should be recorded on-chain in addition to within any centralized system. This would make content voting public and available for automated analysis. While currency may not be revocable, karma is revocable at the discretion of the community and content vote analysis, and the threat of karma revocation, could be employed as an additional deterrent against manipulation.
