Proof Checking Electrum Wallet verifies all the transactions in your history using SPV. I understand that Electrum has a smaller word library (128 bit) than a hardware wallet (256 bit), so brute forcing just one random Electrum seed phrase would take like a million years versus like 10 million for hardware wallets. However, for best security, the official Bitcoin client (bitcoin-qt) should be seriously considered for balances of Bitcoin representing serious financial value.

Electrum 2 is a major upgrade from Electrum 1.As above, confirmed transactions are verified via SPV.This means the client sacrifices some privacy to the server, as the server can now reasonably guess that all these addresses belong to the same entity. It also synchronizes the existing history of its addresses. The client subscribes to its own addresses (nit: sha256 hashes of scriptPubKeys) so that it would be notified of new transactions touching them.One of the servers, arbitrarily, is selected as the “main” server.
