What is Homomorphic Encryption and How is it Applied in Blockchain?

Homomorphic encryption (HE) allows performing computations on encrypted data without revealing it. In blockchain, this is a key technology for ensuring privacy. Users can carry out operations while keeping the data secret. An example of HE usage is blockchain systems such as **Zcash**, which already use this method for private transactions. The technology makes blockchain safer, allowing the use of confidential data without the risk of leaks.
