# Threshold Encryption

To solve the MEV crisis, FOGEVM implements Threshold Encryption for transaction propagation.

* **The Problem:** On Ethereum, transactions are broadcast in plaintext. Everyone sees them before they are confirmed.
* **The Solution:**

1. **User Side:** The user's wallet generates a transaction and encrypts it using the network's Public Key.
2. **Propagation:** The encrypted blob is broadcast to the network. No node can decrypt it individually.
3. **Consensus:** Once the transactions are ordered into a block by the Sequencer, the validator committee collaborates to construct the Decryption Key.
4. **Execution:** The block is decrypted and executed only after the order is finalized.

* **Outcome:** Front-running is physically impossible because the "front" of the line is determined before the data is revealed.
