And for buyers either...You have to own 2 times the value of what you buy ?
I think a lot of you discussing "double escrow" are missing the point. Double does not mean twice the price, it means both sides. From what I see, escrow amounts would be agreed upon not fixed at double the items cost.
Please show where in the FAQ it says double the cost of the item in escrow...
I believe the confusion stems from a simple example David provided awhile back. The idea is simply that in order to make it
extremely unlikely for fraud to occur in the case of an unknown buyer, if the seller required a 100% escrow from their side... then it would be virtually inconceivable that they would not commit to accepting their side of the deal.
There are a number of aspects that haven't been dealt with from a practical standpoint... but to his credit - there's already more to show (in Halo) than I can see on the Etherium side, IMO.
On the other hand, there isn't any
concrete evidence that smart contracts will ever be used for much beyond simple transactions in rare cases. On the other hand, it might be as disruptive to the current system of contractual agreements and trade negotiation that smartphones or twitter are to personal communication... which is
actually the case is anyone's guess at this point.
