McKinsey estimates that there'll be two Key growth horizons for blockchain more than another decade:

Currently, data storage is centralized in significant centers. But if the earth transitions to blockchain For each and every market and use, its exponentially expanding sizing would call for a lot more Superior methods to help make storage far more effective, or power contributors to continually up grade their storage.
