Excellent work here Dan. Social proof of identity is simply brilliant, and necessary in an increasingly tokenized world.

One question: I assume the $1000 posted in the case of a dispute works like a bond in the sense that it is only paid if the dispute was not upheld (ie. the person raising the dispute made a bogus claim)? If the dispute was not rightful, they should lose the whole $1000 but perhaps there is a much smaller admin fee if the dispute was rightful and justice was served? It would suck to lose your keys and then be out $1000 to get them back.
