According to the Dimensionality Reduction Security Lab, users of Bitcoin wallet Electrum are currently facing phishing attacks. The hacker broadcasts a message to the Electrum client through the malicious server, prompting the user to update to v4.0.0.

In short, the public key is only a number that multiplies the two private keys. If the numbers used are large enough, it will take a lot of computation and time for others to find them.

## Enter your own Electrum server

Shunto touch melon, open the github of the electrum, we find the following code in the electrum/electrum/ecc.py.

With the public key, you can generate an encrypted ID - your equivalent identity. The ID of the equivalent node is essentially the encrypted hash of its public key. This ID enables the equivalent nodes to find each other and authenticate after connecting.

So once you lose your private key, it's almost impossible to find it again, so you should put it in a safe place.
