This is why I think wallets like Electrum (or maybe even online wallets) are more practical for a majority of people. The blockchain necessary for Bitcoin-Qt, MultiBit, et al., is currently [over 10 GB][1] and is growing rapidly. It is clearly not ideal for everyone to sync the blockchain, especially for new users that have to download it from scratch.

- wcoenen 13y agoYou don't need to rely on a server. With Simplified Payment Verification (section 8 of the bitcoin paper[1][2]) you can verify payments by querying untrusted peers, without downloading the full blockchain. Bitcoin Wallet[3] for Android and Multibit[4] do this, which is probably why they are now the recommended clients and Electrum is not. Edit: apparently Electrum also double-checks what the server is saying with SPV. I'm a bit fuzzy on why it still needs a server.
