+
+## Abstract
+
+This Meta CIP lists the CIPs included in the Peppermint network upgrade.
+
+## Specification
+
+### Included CIPs
+
+- [CIP-21](./cip-21.md): Introduce blob type with verified signer
+- [CIP-24](./cip-24.md): Versioned Gas Scheduler Variables
+- CIP-XX: limiting compute per block
+
+All of the above CIPs are state breaking, and thus require a breaking network upgrade. The activation of this network upgrade will be different from previous network upgrades, as described in [CIP-10](./cip-10.md).
+
+## Rationale
+
+This CIP provides a complete list of breaking changes for the Peppermint upgrade, along with links to those CIPs.
+
+## Security Considerations
+
+This CIP does not have additional security concerns beyond what is already discussed in each of the listed CIPs.
