Understand Fully Homomorphic Encryption (FHE) in 3 Minutes: A Magic for Protecting Privacy

The secret hidden in the magic box Imagine you have a magic box filled with precious photos, locked with a key that only you possess.

You want your friend to help you organize photos, such as arranging them in chronological order, but you don't want him to see the content of the photos. The traditional method is: you have to unlock the box first, take the photos out for him to see, so he can organize them. But in this way, your privacy is exposed!

Now, a super magic has arrived - fully homomorphic encryption (FHE)! This magic allows your friend to organize photos directly in a locked box without opening it or seeing the photos. You give the locked box to your friend, and he uses a magical tool (algorithm) to operate inside the box, and when finished, he returns you a neatly organized box that is still locked.

You unlocked it with a key, and the photos were perfectly organized, but your friend had no idea what was in the pictures!

💎 What is FHE?

FHE (fully homomorphic encryption) is like this magic box. It is a super powerful encryption technology that allows data to be processed even while in an encrypted state. Whether stored in the cloud, shared with companies, or used on the blockchain, your data remains locked, and others (including service providers) cannot see the contents, but they can still help you complete calculations or services.

Why is FHE the savior of blockchain? Blockchain is like a public ledger where everyone can see all transactions.

FHE is like adding a magical lock to every record in the ledger: transactions are recorded and verified as usual, but your specific information (such as amount, identity) is not visible to others. In this way, the blockchain maintains transparency while protecting privacy.
