This protocol describes a simple payment channel protocol, such as the one presented in https://en.bitcoin.it/wiki/Contracts#Example_7:_Rapidly-adjusted_.28micro.29payments_to_a_pre-determined_party

JSON-RPC methods shown here may be sent via HTTPS or stratum protocol. It is easily adaptable to protocol buffers or another favored marshalling method.

Open channel

Client requests a public key. Server responds with a public key (K2). K2, converted to a bitcoin address, forms the unique identifier for this payment channel. Each public key returned must be unique.
