In short, if you are looking for a Bitcoin wallet, then you must try Electrum.
Electrum is a popular software wallet that works by connecting to a dedicated server. These servers receive a hash of the Bitcoin address in the wallet and reply with transaction information. Electrum Wallet is fast and has few resources, but by default, it connects to these servers and can easily monitor users. In addition to Electrum, some other software uses public Electrum servers. By 2019, it is a faster and better alternative to BIP37.
Bitcoin Wallet Electrum Wallet was hacked and lost 1,450 BTCs.
Shunto touch melon, open the github of the electrum, we find the following code in the electrum/electrum/ecc.py.
If someone's Electrum wallet connects to one of these servers and tries to send a BTC transaction, they see an official message telling them to update their Electrum wallet, as well as a scam URL.
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 much as 71% of the total, and the show did not fully count that hundreds of bitcoins had been stolen in this phishing attack over the past year or so.
Electrum Wallet is one of the most popular Bitcoin wallets and has been around for several years. However, Electrum wallet users often rely on electrum servers, which presents some security and privacy trade-offs. If you use an Electrum personal server, Electrum wallet users can connect locally to their own private servers, enjoying the convenience of Electrum without any trade-offs.
In the end, you've completed your first transaction with the Electrum Wallet.
