As mentioned earlier, because electrum light wallets are different from Bitcoin light wallets such as MultiBit or Breadwallet, they cannot communicate directly with bitcoin full nodes and can only communicate with electrum.
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.
Way I think it is likely to be the adoption of Bitcoin multi-sign mode, Bitcoin multi-signature simply said, is to send a transaction, need multiple accounts to sign the transaction together, and then broadcast to the network, can really execute, of course, now support multi-sign wallet is not really a lot, if you are interested, you can try electrum wallet, we all know that Bitcoin is using the mode of unspent transaction output, which is very different from the Account mode of Ethereum, Although Ethereum also supports multiple signatures, of course, in the Ethereum wallet, multi-signing is actually the deployment of a smart contract, but the problem is that each multi-contract is about 0.02 Ethereum, so if you deploy a large number of multi-signature, then it will be very troublesome, and for mykey, it is also very costly, so it is only using a special contract to manage our account. For Bitcoin, the establishment of multi-signature wallet does not need to deploy contracts, where Bitcoin multi-signature is actually implemented on an algorithmic, so Bitcoin multi-signature will be 0 cost deployment.

Electrum is a world-renowned Bitcoin light wallet with a long history of multi-signature support and a very broad user base, many of which like to use Electrum as a cold wallet or multi-sign wallet for Bitcoin or even USDT (Omni). Based on this usage scenario, Electrum is used less frequently on the user's computer. The current version of Electrum is 3.3.8, and previous versions of 3.3.4 are known to have "message defects" that allow an attacker to send an "update prompt" through a malicious ElectrumX server. This "update tip" is very confusing to the user, and if you follow the prompt to download the so-called new version of Electrum, you may be tricked. According to user feedback, because of this attack, stolen bitcoins are in the four digits or more. This captured currency theft attack is not stealing the private key (electrum's private key is generally stored with two-factor encryption), but replaces the transfer destination address when the user initiates the transfer. Here we remind users that when transferring money, special attention needs to be paid to whether the destination address has been replaced, which is a very popular method of currency theft recently. It is also recommended that users use hardware wallets such as Ledger, and if you pair it with Electrum, although the private key does not have any security issues, you should also be alert to the replacement of the destination address.
