Revisiting Security of Crypto Assets


Crypt-asset exchanges are suffering from incessant hacks, losing a decent amount of crypto-assets of their customers. While it is imperative to enhance the security of the system as a whole, including functions outside of the blockchain, now is the time to learn a lesson from past incidents and to find out the root cause of the issue.
