Stanford PhD student: MimbleWimble may not be as private as originally thought

Florian Tramer, a doctoral student in computer science at Stanford University, said MimbleWimble may not be as private as people originally thought. These privacy coins came about because people realized that Bitcoin's security is not what people once thought. The way MimbleWimble works is to combine multiple transactions into one package, which is to make it more difficult for cryptocurrency hackers to collect data for a single transaction. But as long as the attacker has the technical ability, they can easily set up a super node so that they can check the data of all transactions in it. They can then use the node to separate transactions and see the identity of all involved parties. It is reported that MimbleWimble is a blockchain privacy protection format and protocol. It is a technology that can prevent the blockchain from leaking personal information.
