Well as we all know that whenever we transact it always go through blockchain first. So is it possible that blockchain can detect illegal trasanction such as buying drugs, guns, hitman etc., especially on deepweb. And where does bitcoin go when blockchain detects a illegal transaction?
Ofcourse not.
How a website that keeps track of the wallets and the funds being transacted between each other can detect an illegal transaction?
Blockchain only can show you that what amount and from what wallet it was transacted from, but it cannot give you or keep any other information about that.
Because bitcoin is anonymous, it cannot be tracked i guess.
