bitcoinj is a Java implementation of the Bitcoin protocol, which allows it to maintain a wallet and send/receive transactions without needing a local copy of the official implementation. It comes with full documentation and some example apps showing how to use the library. The project aims to be easier to understand than the C++ implementation, and be suitable for usage on constrained devices such as mobile phones or cheap virtual servers. bitcoinj implements both the lightweight "simplified payment verification" mode of Satoshis paper which does not store a full copy of the block chain or verify all transactions, and anexperimental full verification mode.
