Gavin Wood has announced the initial launch of Parity’s JAM SDK, written in Rust. While still in an early stage of development, it is functional for the development of JAM services and authorizers. It currently consists of three components: JAM Types and PVM Common is the basic API of the SDK which provides the necessary tools for creating Services and Authorizers. JAM Bootstrap Service and Null Authorizer consists of two basic PVM modules to help set up a basic configuration suitable for JAM Genesis. JAM PVM Builder is a tool to compile and package services or authorizers into executable PVM binaries for JAM.
