Security experts: Creating a unified blacklist is not only difficult to operate, but also insufficient to solve the fraud problem in the encryption field.

According to Cointelegraph, BlockShow Asia 2019 participating security experts agreed that creating a unified blacklist for fraudsters is not only difficult to operate, but also insufficient to address fraud in the encryption field. A cryptocurrency service provider like an exchange already has its own blacklist, and it might seem useful to combine these into one list, but it's not easy. Marina Khaustova, CEO of Crystal Blockchain Analytics, said there are limitations to creating a unified blacklist, and just checking blacklists is not enough to define fraud.
