This repository contains the specs for vac, a modular peer-to-peer messaging stack, with a focus on secure messaging. A detailed explanation of the vac and its design goals can be found here.

Status

The entire vac protocol is under active development, each specification has its own status which is reflected through the version number at the top of every document. We use semver to version these specifications.

Protocols

These protocols define various components of the vac stack.

Waku

Waku is a protocol that replaces Whisper (EIP-627). Waku v2 is an upgrade of Waku v1 that is in active development and offer significant improvements. You can read more about the plan for it and an update.

Style guide

Sequence diagrams are generated using Mscgen like this: mscgen -T png -i input.msc -o output.png. Both the source and generated image should be in source control. For ease of readability, the generated image is embedded inside the main spec document.

Alternatively, mscgenjs can be used to generate sequence diagrams (mscgenjs produces better quality figures especially concerning lines' spaces and figures' margins). Once installed, the following command can be used to generate the sequence diagrams mscgenjs -T png -i input.msc -o output.png. More details on the installation and compilation are given in mscgenjs repository. You may try the online playground https://mscgen.js.org/ as well to get a sense of the output figures.

The lifecycle of the specs follows the COSS Lifecycle

Meta

The keywords “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC 2119.

Linting

Spellcheck

To run the spellchecker locally, you must install pyspelling.

It can then be run with the following command:

pyspelling -c .pyspelling.yml

Words that should be ignored or are unrecognized must be added to the wordlist.
