Great call today! I didn’t ask this because it felt less relevant to the participants (mostly Cosmos validators) but I’m particularly interested in the security considerations for implementing a sidechain (appchain?) using the Cosmos SDK.
Questions like:
- what known attacks exist at the app layer?
- what common issues and gotchas should be avoided?
- what are the recommended best practices for secure development?
- what are best practices for upgrading a sidechain?
