The SIPs describe the design, implementation, and governance of the Stacks 2.0 blockchain. The SIP process (SIP-000) describes how to make a SIP and get it ratified. Anyone in the Stacks community may submit a SIP.

There are several ways you can get involved with the SIP process:

• SIP Editor. SIP editors help SIP authors make sure their SIPs are well-formed and follow the right process. They help get SIPs ready for deep review by advancing it them from Draft to Accepted status. If you want to become a SIP editor, open an issue with your name and email to ask to be added to the list of SIP editors.

• Joining a Consideration Advisory Board. SIPs fall under the purview of one or more considerations, such as "technical," "economic," "governance," and so on. A full list is in the considerations/ directory. Members of SIP consideration advisory boards use their domain expertise to give Accepted SIPs a deep read, and give the authors any/all feedback to help make the SIP workable. If you want to join a board, reach out to the board's chairperson via the listed contact information.

• Creating a Consideration Advisory Board. Anyone can create a consideration advisory board by opening a PR to create a new consideration track, and SIP authors can opt to have you review their work by adding your consideration to the SIP's list of considerations. You are expected to vote on such SIPs in a fair and timely manner if you start a board.

• Steering Committee. The Steering Committee organizes the consideration advisory boards and votes to advance Recommended SIPs to Activation-in-Progress status, and then to either Ratified or Rejected status. Once they are in the process of being activated, they use a SIP's Activation section to determine whether or not the Stacks ecosystem has ratified or rejected the SIP. Joining this committee requires the consent of the Stacks Foundation board.
