Cap-theorem. Blockchain allows for far greater partitions not available to any other database model. In terms of consistency, while I disagree with everything many crypto companies are doing, when it comes to consistency, blockchain allows far larger scabability in terms of consistency over a larger partition than traditional corporate servers running Hadoop or Spark. The availability is surprisingly quick as well. If we're talking maximum scale of big data and their operating methodology, we're going to be talking about blockchain and how to partition the the data between different clusters and how to achieve consensus between nodes. Financial data belongs on the blockchain, outside of corporatocracy control and central bank control.
