By default, electrum wallets are randomly connected to a set of Electrum servers. From a privacy perspective, this is not a good thing because it discloses your wallet address and balance to unknown third parties.

First of all, the Bitcoin system replaces the credit of the central intermediary and does not guarantee the credit of both parties to the transaction, so if there is a credit problem on both sides of the transaction, then the transaction cannot be cancelled according to the non-tamperable nature of the ledger.
