One thing that still frustrates me about blockchain is how fragmented everything feels. An application on one network doesn't automatically work with another. Moving assets and information between ecosystems often introduces additional infrastructure, bridge dependencies and security considerations. Interoperability needs to become more than simply transferring tokens. That's why @RialoHQ 's Interop direction deserves attention. The bigger goal is making communication across different blockchain environments easier. Think about applications that can coordinate activity across networks without forcing users to understand every underlying connection. Less fragmentation. More connected applications. A blockchain ecosystem becomes much more useful when its networks can work together.
