Decentralized Reputation Systems

More like Web of Trust with reputation scores.

Isn't this the whole point of a reputation system?

you could achieve some trust through a reputation system. the longer you've been reliable the more reliable you are.

Look are github.com/neyer/respectOr s3.neyer.me/respect-matrix-slides.pdfThe solution is to do reputation on a pairwise basis. Recursively Expand the network of people you trust.

It's not a social credit system!! It's empowering users to track their own view of reputation, as opposed to having an authority determine it.

How does one run a reputation system without knowing whose reputation one is calculating?

I'm glad people are thinking about this. Reputation systems should allow Markov Chaining, a la Google's PageRank algorithm. This would be a great help, but with a drawback or two as well. For example, smart rebels or people who genuinely know surprising things would need to find a high-reputation sponsor or they would likely get downvoted to oblivion; but other institutions have strong mentorship mechanisms to counter such tendencies, and so promote innovation and novelty.

This has been on a couple of times. It's an interesting concept but user's reputation isn't really stored anywhere. It's just a synch of data between peers. So someone can very easily simulate many points, or upvote content several times.

Wasn't all this supposed to be solved in the 90s with "web of trust"? Rather than trusting every review, you only trust those from your personal circle of friends, and then from their friends but with less weight, etc.

A reputation system could solve this. Do that a few times in a given time period and you become persona non grata.
