51% Attack

This term “51% Attack or Majority Attack” defines a type of attack that involves gaining a major mining power for any particular Cryptocurrency. With this, the miner gets access to a 51% or more “hash rate” for the currency where he can reframe any previous transactions. But there can be one problem: “malicious attack”. With this the crypto can pass in two different addresses at the same time. This way attackers steal crypto from authentic users. To stop this there needs to be a joint attempt from all authentic users.
