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.

Technical note

The Challenges of Packaging Bitcoin Software

Introduction

Bitcoin technology is complex. Under the hood of the decentralized virtual currency lies a novel form of decentralized, distributed database. It is critical for users, system adminstrators and packaging engineers to understand bitcoin's database consistency model, which is radically different from familiar database consistency models (MySQL, Berkeley DB, Amazon Dynamo, or Google's GPS-based doohickey).
