This update prompt is not an official act of Electrum, but a phishing attack by an attacker that exploits a message flaw on the Electrum client and the ElectrumX server, which requires the attacker to deploy the malicious ElectrumX server in advance, and the malicious server is localized by the user's Electrum client (because the Electrum client is a light wallet and the user needs the ElectrumX server to broadcast the transaction). At the time of the madness, malicious ElectrumX servers accounted for as many as 71% of the total, and according to incomplete statistics, hundreds of bitcoins have been stolen in this phishing attack over the past year or so.
In this demo, Electrum developer Chris Belcher shows how to set up and use an Electrum personal server.
Install the Electrum wallet and configure it to use Tor or the Data OS operating system.

In August-September, Bitcoin wallet Electrum was hacked twice, and according to multiple sources, at least 1,450 BTCs worth $11.6 million were stolen from phishing attacks that faked Electrum upgrade tips.
If you haven't set up Electrum Wallet to be compatible with your phone wallet, you can use the private key to recover the Electrum wallet on your web wallet. Select Wallet - "Private Key" - "Export" on the Electrum wallet and you will export the file qtum-electrum-private-keys.csv or copy only one private key. Select Recover from WIF on your web wallet, paste the private key, and select Confirm. Check that the wallet address is correct. You may need to use Dump as a Key File to save the key file.
Bitcoin Core is the standard software client for the Bitcoin network, and its version 0.16.0 adds full support for Isolated Witness (SegWit). In early February, a Github announcement foreshadowed the plan's release.
According to Reddit user u/normal_rc, electrum's wallet was hacked and nearly 250 bitcoins (243.6 BTCs, nearly $1 million) were maliciously stolen, according to coinelegraph. Electrum then confirmed that the attack included creating a fake version of the wallet to trick users into providing password information. Electrum responded on Twitter that "this is a persistent phishing attack on Electrum users" and warned users not to download Electrum from any source other than the official website.
According to The Next Web, the attackers even implemented their own Electrum servers, which hosted the attacked Electrum.

It's not hard to run your own Electrum server and point your wallet to just use it. This restores Electrum to the point where it has the same privacy and security attributes as the full node, where no one else can see the address or transaction that the wallet is interested in. Electrum then becomes an all-node wallet.
Transactions made on Bitcoin cash from nested quarantine witness addresses violate one of these standard rules (to be precise, clean stack rules) and are therefore not relayed; As a result, miners or users who are directly in contact with miners can consume from nested SegWit addresses on Bitcoin cash, wherea they cannot.
Note: Electrum-XZC is derived from Electrum and uses different seed phrase criteria, so it cannot be imported.
electrum segwit or standard verge
If most miners still don't deploy SegWit2x, or accept SegWit instead, and UASF supporters don't budge, there could be two versions of Bitcoin blockchain: one supported by UASF, which can only approve SegWit transactions, and the other that approves all transactions, whether SegWit or non-SegWit.
Bitcoin Wallet providers like Trezor and Electrum.
rpcserialversion: Set the return value of the original transaction or block in non-verbose mode, with only two values, 0 for non-segwit, 1 for segwit, and the default value is 1.
According to segwit.5gbfree data, the number of segwit transactions in the Bitcoin blockchain has started to rise since the 4822200 block, and so far there have been more than 1% of segwit transactions in two blocks. Over the past week or so, the number of segwit transactions per block has hovered around 0.3%.
A new repo qtum-electrum-new has been built to add qtum-related features to the latest code for Bitcoin electrum.
