Peer Protocol

Peer Protocol for Channel Management

To exemplify the protocols as we define them, we will assume there exists a multisignature wallet shared between two parties, Alice and Bob. This is the only required re-usable on-chain component (with the exception of supporting libraries) to execute each of the protocols below.
