Been talking to some people about escrow, one of the systems requires users to put the cost of a item in escrow time two.

For instance you buy a miner for 5BTC  you must put 10BTC into escrow.

The seller is also required to put up the cost of the item into escrow.

If you and the other person do not agree you and the seller lose all the coins to the escrow system. So the system would get 15BTC from the dispute.

Would you use a system like this?
