Buyers will have to spend more time researching vendors and moderators, then agreeing with a vendor on a moderator which will be difficult as no moderator can be 100% impartial and the largest 5-6 (that will develop due to natural economies of scale) will develop their own brands and reputations for being easy on buyers, easy on sellers, random coin toss, etc. Where is this cost made up for the buyers - will they see lower prices? Wouldn't it be more expensive as moderators need to be compensated for their services?
Also, from the pitch deck linked in the article [1] slides 48-51:
What about moderator reputation? Difficult problem to solve as there will always be on party that is happy with the result, and one that is unhappy. Transparency is the best approach...Negative or positive consensus on the quality of dispute resolution will inform Vendors and Buyers
How can there be a consensus on a moderator if one party is always happy and one is always unhappy? Won't the consensus always be 50/50?
Also, how do you plan to scale up transparency? Is that mostly a UX/UI challenge, or is there some clever mechanism to solve this through cryptographic/social hacking?
Last question: How will the leadership/dev of OpenBazaar be structured in the future? Will you guys develop something similar to the Linux Foundation under a non-profit charter? Will the foundation enact a transaction fee to fund itself?
Sorry for the barrage - just extremely interested as someone who has studied Bitcoin/blockchain tech in the past.
