Why does monerod consume so much CPU?
I'm on an i7 core but monerod consumes up to 300% CPU at times. When I am catching up on the blockchain, it renders my computer nearly unusable. Is this normal?

Is it possible to build a BitcoinJ style library that will help enable lightwallets?
As I understand it, lightwallets are inherently difficult for CryptNote currencies because the wallet has to scan every block in the blockchain. This means they can't just request block headers to verify the chain and use bloom filter requests to…
