@M ... equity DVC ... this is one level up better than 'Permanent storage' ... you hit the key word ... EQUITY ... proving you've held uno on the blockchain thus grants equity points ... bonus for HODL'rs!
But the concept (if I read right?) with this pass to the TT on the left might be 'Halo' without the messy code.
In effect ... Alice gives Bob 10kg of UNO 'her Equity' (Bob is the Trustee/Custodian) ... If Bob goes bad/rogue then he forfeits 'his Equity' held by Charlie ... Bob's 10kg goes to the Blue Crypto Fund. [I would rather give it back to Alice since she's now out 10kg] .... Another twist to help the Blue Crypto Fund ...
Layer1 >> Bob goes rogue but Alice gets 10kg back (Bob's Equity held by Charlie)
Layer2 >> pass to the TT on the right 1kg ... Bob also put 1kg of equity in Alice's keep ... she pushes that off into the Blue Crypto Fund.
THE SCORE::
Alice (-10kg+10kg) ........ evens
Blue Crypto Fund (+1kg) .. +1kg
Bad Bob (-11kg+10kg).... -1kg
++++++++++++++++++++++++
now for real SuperMax Game Theory
We assumed Charlie is a good guy. I also assumed a trading house the size of Gox would never go rouge ... ha ha cry
But we can chop Charlie into the whole TT list ... A-Z super distributed ... so everyone but Alice holds a slice of her 10kg.
Sounds awesome! I won't flake out on you. Just don't chop me up!
