If you spot suspicious transaction what you can do to reverse it back?
In my knowledge blockchain transaction will never be reversed unless and until destination address wanna send it back to the depositor! If you want to create any cryptocurrency it is not at all possible option for you crypto is to secure the transaction with just p2p technology.
None of the people or equal middleman will not be e involved in it.
I don't think the transaction can be reversed but the wallets can be traced back to the user especially if multiple cases of money are moving. I know that's what Ciphertrace's tech does and I think it's much more reasonable than looking to reverse transactions. They are trying to stop them before they happen.
