This repository contains the formal LaTeX specification of the JAM (Join-Accumulate Machine) protocol, a proposed blockchain system by Dr. Gavin Wood. It is not a software application but a reference document defining the protocol's state transitions, cryptographic primitives, virtual machine (PVM), consensus mechanism (Safrole), and accumulation pipeline. The codebase consists entirely of LaTeX source files, a bibliography, build scripts, and assets for generating a PDF. The specification is mathematically rigorous and structured for formal verification or implementation. While not a runnable system, it demonstrates high craftsmanship in consistent notation, modular sectioning, and automated build processes. The project is actively maintained with versioning and spell-checking, but lacks automated testing or CI for the specification itself.
