The real innovations of blockchain and decentralized consensus, are true ownership of digital things and truly scarce digital things. The way the current digital world works is as though we were ok with owning houses exclusively based on the promises of a homeowners association; we don't actually own our data on most sites we use. True digital ownership gives control back to the owner and changes the rules of the internet. One can now prove digital scarcity, break through the walled gardens of third-party services, increase interoperability between systems, and control one's data.
