Light client
Bitcoin-S comes bundled with a light client Bitcoin node. this client is capable of doing verification of some parts of the blockchain, and can act as a starting point for building Bitcoin applications that need to connect to the P2P network.
This node is currently only released as a library, and not as a binary. This is because it (nor the documentation) is not deemed production ready. Use at your own risk, and without too much money depending on it.
