electrum 3.2.3 synchronizing
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 wallets are fast and have 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.
On December 27, Reddit user u/normal_rc reported that Electrum's wallet had been hacked and that nearly 250 bitcoins (243.6 BTCs, nearly $1 million) had been maliciously stolen, coinelegraph reported. 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.
Now, even if 10,000 or even 100,000 people want to pledge, the problem of synchronizing all these nodes is gone. Synchronizing 100 participants is not a big problem, our initial example is a power of 2, if there are 10 recipients need to get a new block, it takes 7 stages, for simple information transmission, 2 stages is enough.
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 this demo, Electrum developer Chris Belcher shows how to set up and use electrum personal servers.
My Bitcoin wallet has been repaired. When blockchain updated their application, I remember that my password was wrong. I'm signed in to the system. Then I try to sign in again using Pin (the only "password I know"). I've never backed up my seed phrase, it's an expensive course.
Electrum hackers pre-empted a large number of "normal" electrum servers on the P2P network.

In addition, electrum Wallet generates a backup recovery seed that does not require any personal information at the time of registration, and it is layered.
