# Algorand ARCs

Welcome to the Algorand ARCs (Algorand Request for Comments) page. Here you’ll find information on Algorand Improvement Proposals.
New ideas for ARCs are discussed through [Pull Requests](https://github.com/algorandfoundation/ARCs/pulls) — you can find and contribute to them in the [ARC repository](https://github.com/algorandfoundation/ARCs).

## ARC Status Terms

- **Idea** - An idea that is pre-draft. This is not tracked within the ARC Repository.
- **Draft** - The first formally tracked stage of an ARC in development. An ARC is merged by an ARC Editor into the ARC repository when properly formatted.
- **Review** - An ARC Author marks an ARC as ready for and requesting Peer Review.
- **Last Call** - This is the final review window for an ARC before moving to FINAL. An ARC editor will assign Last Call status and set a review end date (`last-call-deadline`), typically 14 days later. If this period results in necessary normative changes it will revert the ARC to Review.
- **Final** - This ARC represents the final standard. A Final ARC exists in a state of finality and should only be updated to correct errata and add non-normative clarifications.
- **Stagnant** - Any ARC in Draft or Review if inactive for a period of 6 months or greater is moved to Stagnant. An ARC may be resurrected from this state by Authors or ARC Editors through moving it back to Draft.
- **Withdrawn** - The ARC Author(s) have withdrawn the proposed ARC. This state has finality and can no longer be resurrected using this ARC number. If the idea is pursued at a later date it is considered a new proposal.
- **Deprecated** - This ARC has been deprecated. It has been replaced by another one or is now obsolete.
- **Living** - A special status for ARCs that are designed to be continually updated and not reach a state of finality.
