What are ZIPs?
Zcash Improvement Proposals (ZIPs) are the way to:
- propose new features for the Zcash cryptocurrency and their rationale,
- specify the implementation details of the feature,
- collect community input on the proposal, and
- document design decisions.
Contributing
The authors of a ZIP are responsible for building consensus within the community and documenting / addressing dissenting opinions.
Anyone can write a ZIP! We encourage community contributions and decentralization of work on the Zcash protocol. If you’d like to bounce ideas off people before formally writing a ZIP, we encourage it! Visit the ZcashCommunity Discord chat to talk about your idea.
Participation in the Zcash project is subject to a Code of Conduct.
The Zcash protocol is documented in its Protocol Specification.
To start contributing, first read ZIP 0 which documents the ZIP process. Then clone this repo from GitHub, and start adding your draft ZIP, formatted either as reStructuredText or as Markdown.
For example, if using reStructuredText, use a filename matching draft-*.rst.
Use make to check that you are using correct
reStructuredText or
Markdown syntax,
and double-check the generated draft-*.html file before filing a Pull Request.
