How about create a new address type for exchanges

[HelloGuy]

Recently the hack of BFX remind us how easily the exchange been affected by hackers. We should create a new address type for the security of exchange/wallet service which carry out deposit or custody responsibility for users. These address's transaction should have kind of feature that any transaction with UTXO on it, can be reversed in a given time, like 24 hours, or 144 block.

All the exchanges will save the funds in these type of address.

So that if an exchange get hacked, they will be able to reverse these transactions.

The problem is how not to let ordinary wallet users being scammed by a potential attack. Someone may send fund using this type of address and asking for delivering of goods/fiat money and then reverse the transactions.

I think you'll need to specify this idea much more formally and specifically in order to create discussion...

@theZerg sorry for the informality.

I found email discussion in the Core development team, which is discussing a new type of address serving the clearing house. The responses are also very interesting.

Please take a look at it:

I looked at it. The next step is to distill that conversation into pros and cons and then discuss validity of the arguments and ramifications of the idea.
