RSK Improvement Proposals

RSKIP status terms

• Draft - an RSKIP that is open for consideration
• Accepted - an RSKIP that is planned for immediate adoption in the reference client, i.e. expected to be included in the next reference client release.
• Adopted - an RSKIP that has been adopted in a previous reference client release.
• Deferred - an RSKIP that is not being considered for immediate adoption in the reference client. May be reconsidered in the future for a subsequent release of the reference client.
• Rejected - an RSKIP that was rejected

RSKIP purpose terms
