Individual users can activate Blockstream Esplora's lightweight mode, significantly reducing disk space requirements, but at the expense of reduced scalability and DoS resistance. Lightweight mode still provides blockchain browser and Electrum server functionality, and performance is sufficient for a home or small office.
Bitcoin Future： electrum server version
Users of Bitcoin wallet Electrum are currently facing a phishing attack, 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 follows the prompt to install the backdoor-carrying client, the private key is stolen and all digital assets are stolen. At the time of writing, at least 1,450 BTCs worth approximately $11.6 million had been stolen from phishing attacks that forged Electrum upgrade alerts. 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.
Bitcoin Wallet Electrum has released the official version of 4.0, adding features such as Lightning Network and PSBT.
The latest version of UBTC Electrum Light Wallet v3.2.8 is available for download.
The Electrum development team also warned them that they had nothing to do with a project called Electrum Dark: they used our name without our permission. Be careful with the altcoin version of Electrum, as they are sometimes used as vectors to install malware against your real Bitcoin wallet.
In an April 29 blog post, Malwarebytes, an antimalware software company, said the number of infected Electrum Bitcoin wallets had reached 152,000 after the server was attacked by DoS. Malwarebytes found that the number of infected machines in botnets had reached 152,000, and the total amount of stolen funds had risen to $4.6 million. The company identified a loader called Trojan.BeamWinHTTP, which also involved downloading previously detected Electrum DoSMiner. The largest botnets are reported to be concentrated in asia-Pacific, Brazil and Peru, and botnets attacking Electrum infrastructure are growing. (Cointelegraph)
Hackers launched a denial-of-service (DoS) attack on a well-known wallet Electrum server, according to Johnwick.io. Hackers used botnets of more than 140,000 computers to attack Electrum nodes and simultaneously deployed malicious nodes. When a user connects to these malicious nodes and sends a transaction using an older version of Electrum, the user is prompted to update the Backdoor Client. If the user installs the client as prompted, the private key is stolen and all digital assets are lost. Millions of dollars of digital currency have been stolen, according to Electrum officials. De-dimensional Security Labs recommends that users of electrum wallets be updated to the latest version of the client through the official website and never use the link in the prompt message.
Qtum Electrum is a Qtum desktop light wallet modified from the well-known Bitcoin wallet Electrum. Compared to the current Qtum Core full-node wallet, Qtum Electrum takes up less disk space and takes less time to synchronize chunks, supports multi-signature and hardware wallets, supports cold wallet mode, supports the import of mnomes into mobile wallets, and uses SPV authentication to ensure security.
It is understood that the issue only affects users who use the Ledger Nano S device to access their XMR wallet.
Once everything is set up, you can use Electrum. Have Fun.
So what kind of process does this deal confirm? Why do I need 6 block confirmations?

Hackers have launched a denial-of-service (DoS) attack on a well-known wallet Electrum server, according to Johnwick.io. Hackers used a botnet of more than 140,000 computers to attack Electrum's nodes and simultaneously deployed malicious nodes. When a user connects to these malicious nodes and sends a transaction using an older version of Electrum, the user is prompted to update the Backdoor Client. If the user installs the client as prompted, the private key is stolen and all digital assets are lost. Millions of dollars of digital currency have been stolen, according to Electrum officials. Devi Security Labs recommends that users of Electrum Wallet update to the latest version of the client via the official website and never use the link in the prompt message.
The Electrum team has announced the attack in an official tweet, saying that "this is an ongoing phishing attack on Electrum users" and reminding users to check the authenticity of the client's source before logging in. The team published its official website, and electrum clients downloaded elsewhere may be problematic.
Light wallets rely on other full nodes on the blockchain, synchronizing only their own data and partially centralizing them.
