Bitcoin Future： how to fix unconfirmed electrum tranaction
Users of Bitcoin wallet Electrum are currently facing phishing attacks, according to the Devi Security Lab. Hackers broadcast messages to electrum clients through a malicious server, prompting the user to update to v4.0.0, and if the user is prompted to install this backdoor-carrying client, the private key is stolen and all digital assets are stolen. As of 13:00, at least 1450 BTCs worth approximately $11.6 million had been stolen from phishing attacks that forged Electrum upgrade tips. Devi Security Labs hereby suggests that versions of Electrum below 3.3.4 are vulnerable to such phishing attacks, and users using Electrum Wallet are requested to update to the latest version of Electrum3.3.8 via the official website (electrum.org), which has not yet been officially released v4.0.0, and do not use the link in the prompt message to avoid asset losses.
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.

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.
According to an October 25 article from Vergecurrency, the upcoming Verge Core Version 6 can now be tested on Github and released once the pre-release version is tested correctly. Verge also said it had reconsidered the Electrum spectrum and was working on porting the latest ElectrumX server to work with the Verge Core client. "This means that you must upgrade the Electrum client after it is published. Doing so will indicate that you support the new halving schedule. "According to the previously announced timetable, the halving is planned for block 3700,000. (Newslogical)
