My favorite kind of decentralized system is one that allows users to control the amount of data they can while still having the copies of the data replicated on the system. In this way the data is not centralized or held by only few people. Ipfs and certain multi-blockchain network function in this manner.
Another interesting feature of this is the ability to access and share the data offline in remote areas without internet. Now imagine being able to do this with Hive Blockchain so that you can continue using it locally even if you are disconnected from the global network.
