Worked on the IntersectMBO/cardano-ledger repository to enhance the canonical ledger state by introducing a new UTXO/v0 namespace and an OnChain wrapper for type values and binary representations. This approach improved the organization and forward compatibility of the ledger, laying the groundwork for future protocol upgrades and state migrations. Developed the CanonicalCoin type to streamline coin management within the canonical state, consolidating these changes through incremental pull requests. The work focused on maintainability and clarity, leveraging Haskell and blockchain development expertise, and applied advanced data structures to support evolving requirements in smart contract and ledger state management.
