The Scroll Network is a blockchain-based data storage and management platform built on Ethereum. Scroll uses their semi-private blockchain network to address the growing complexities and inefficiencies of current big data systems. The Scroll Network's algorithm adjusts the number of nodes available to host incoming network traffic, depending on demand. All data is encrypted, and there are a variety of permission and monitoring features to further ensure privacy.
