A Tezos Improvement Proposal (or TZIP, pronounced "tee-zip") is a document which offers ways to improve Tezos via new features, tools, or standards (e.g. smart contract specifications).
A TZIP is a design document providing information to the Tezos community, describing a feature for Tezos, interoperability standards, or an update to its processes or environment. The TZIP process complements (but is subsidiary to) Tezos' formal on-chain governance process.
A TZIP should contain a concise technical specification and rationale which unambiguously articulates what the proposal entails, how it may be implemented, and why the proposal improves on the status quo.
A TZIP begins as a TZIP draft. Once adopted, a TZIP draft becomes a numbered TZIP-### (e.g. TZIP-010).
