### High-level tasks

- Knowledge-share on IBC protocol abstractions, security model, implementation details.
- Exhaustively test & debug current Cosmos SDK Golang implementation.
- Conduct internal in-person code reviews to improve code quality & find any latent bugs.
- Get ibc-alpha branch to a functional demo state.
- Update Gaia to incorporate the latest IBC module changes & work with the relayer.
- Remediate issues discovered during IBC audits.
- Read the audit reports, make the issues, later second phase (GH tag).
