When it comes to enterprise features, the priorities are:

• Native Proof of Authority module on the SDK
• Native programmable privacy primitives

For the latter, Cosmos Labs is exploring ZK UTXO and sidecar architectures using TEEs, among other things. https://twitter.com/cosmos/status/2008229870032351441/photo/1
