[![Build Status](https://travis-ci.com/vacp2p/specs.svg?branch=master)](https://travis-ci.com/vacp2p/specs)
This repository contains the specs for [vac](https://vac.dev), 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](https://vac.dev/vac-overview).
## 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](https://semver.org/) to version these specifications.
## Protocols
These protocols define various components of the [vac](https://vac.dev) stack.
- [mvds](./specs/mvds.md) - Data Synchronization protocol for unreliable transports.
- [remote log](./specs/remote-log.md) - Remote replication of local logs.
- [mvds metadata](./specs/mvds-metadata.md) - Metadata field for [MVDS](./specs/mvds.md) messages.
### Waku
Waku is a protocol that substitutes [EIP-627](https://eips.ethereum.org/EIPS/eip-627).
- [waku](./specs/waku/waku.md) - ÐΞVp2p wire protocol, substituting [EIP-627](https://eips.ethereum.org/EIPS/eip-627).
- [envelope data format](./specs/waku/envelope-data-format.md) - [waku](./specs/waku/waku.md) envelope data field specification.
- [mailserver](./specs/waku/mailserver.md) - Mailserver specification for archiving and delivering historical [waku](./specs/waku/waku.md) envelopes on demand.
## Style guide
Sequence diagrams are generated using [Mscgen](http://www.mcternan.me.uk/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.
The lifecycle of the specs follows the [COSS Lifecycle](https://rfc.unprotocols.org/spec:2/COSS/)
## 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](https://www.ietf.org/rfc/rfc2119.txt).
