It currently properly downloads, validates, and serves the blockchain using the exact rules (including bugs) for block acceptance as the reference implementation, bitcoind. It also properly relays newly mined blocks, maintains a transaction pool, and relays individual transactions that have not yet made it into a block. It ensures all individual transactions admitted to the pool follow the rules required into the block chain and also includes the vast majority of the more strict checks that filter transactions based on miner requirements ("standard" transactions).
