Looking for paid developers, check out http://identifi.org/

Is relocation a criteria to join your team ?

Nah. Skill, motivation and a skype account is sufficient.

identifi is one of the critical missing components, it is required and must exist - sirius is a skilled, hard working, and respected.

I would encourage any able developer with any free time to get familiar with the project, and if they subsequently have any motivation then contribute whatever time they can to this project, whether developing, testing, or simply discussing issues.

I for one will do what I can.

Without blockchain, what happens if somebody attempts the pendant of a double spend? E.g. different ratings...

The idea is interesting and could be very useful, but here a lot of work remains to be done about the security of personal data and the reliability of ratings. How are you going to achieve reliability, honesty of the reviews? I think you need a sociologist and a specialist in user experience.
And about the site. Search doesn't work, and fonts are very pixelated (you need anti-aliasing).

Insurance provides recourse that covers both intentional and unintentional damages. Properly implemented insurance systems offer a strict superset of the functionality provided by reputation systems and also don't require privacy compromises.
Suppose I want to go to a restaurant. I look at the reviews on Yelp and I want to attend only to the reviewers who are deemed trustworthy by my web of trust. A reputation system can help me with that. I fail to see how an insurance system, no matter the implementation, can realistically provide a superset of this functionality.

Suppose Alice trusts Bob (in a generic sense), Bob trusts Charlie, and Charlie vouches for Dave as being an excellent food critic. Alice wants to eat at Restaurant X which is in fact a terrible restaurant, but was rated 5 out of 5 stars by 3 unvetted user accounts (all three of which are actually the restaurant owner, unbeknownst to anyone). It was rated 1 out of 5 by Dave. Yelp averages these out for a composite score of 4 out of 5 stars. Obviously this is a misleading average score! How do we solve this problem using web of trust?

I would like to see a solution whereby Restaurant X's average is a weighted average, where Dave's 1-star rating is given a lot more weight than the 5-star ratings by the unvetted users, so that Alice sees that Restaurant X's composite score is (for example) 1.2 out of 5 instead of 4 out of 5. If she wants, Alice can do a visual inspection of her web of trust and trace the connection between her and Dave, but this would be very time intensive and it should not be necessary for her to do this for every single rater of every single restaurant under consideration.

Is it envisioned that identifi will enable a solution like this? If it's not, then we need to develop such a vision.

Addendum: I would like to see a solution that would do all of the above, and in addition would be able to hide some of the connections. For example: suppose Bob wants to keep his connection to Charlie private. There should still be a way for Alice to know that her web of trust tells her that Dave is an excellent food critic and Restaurant X is a bad one, WITHOUT revealing the full connection between her and Dave. I believe that this is very much doable (perhaps using zero knowledge proofs, or maybe other cryptographic tools) but that the first step should be to tackle the more simple scenario where all connections and ratings are public. Then and only then can we turn our attention to the privacy-preserving algorithms.

Thanks for the link, although I don't see anything that addresses my previous post.

My impression from talking to Tim and reading Sirius' whitepaper from a few years ago is that nobody associated with identifi has put forth a vision to tackle the kind of problem in my previous post. In other words, how identifi could provide the foundation for a fully formed pseudonymous reputation system (PRS). Although I would be happy to be proven wrong! Smiley

This to me is the most interesting problem in the crypto space. I have ideas on potential strategies and am working on demonstrating those ideas on my website OpenBazaar.OnTheBlockchain.com which I hope will provide a useful reputation system for OpenBazaar. It is not yet in beta although I hope that's not too far away. Essentially what I am building now is a platform that will calculate average ratings of listings using ratings generated on my site as well as ratings generated on OpenBazaar itself, and will also calculate trust scores of users based on ratings generated on my site. All averages are weighted averages, where the weight of the rating depends on the trust score of the user doing the rating. Unvetted users are given a default trust score which is adjustable by the user and can be set to zero if desired.

I haven't done this yet, but my roadmap includes allowing users to sign json-formatted ratings using a self sovereign identity (like a keybase ID perhaps), and then storing the rating + signature on the ipfs. I haven't learned enough yet about identifi to know whether I could use the identifi library to assist me in this task. Although by a quick perusal, it looks like identifi has functions that will store data in ipfs, so perhaps I can use it.
