7 Ways Blockchain is Being Used for Security

Blockchain is being used as a security tool. If you haven't thought about adopting it, you might want to reconsider your take.

Distributed Storage
Threat actors love large databases. Single entities that contain terabytes of information mean that a single successful intrusion can result in thousands, millions, or tens of millions of records being revealed. Using blockchain, data can be stored on a wide variety of systems, with the integrity of each node - and therefore the database as a whole - guaranteed through the ledger calculations.
One of the important features of distributed storage implemented with blockchain is the integrity of the data. Any time data is changed, no matter who does the changing, the edit must be verified by the blockchain. When it becomes more difficult to change data, one aspect of storage security is more easily dealt with.
As with so much of computing in 2018, this distributed data model has particular application in the IoT, where sensors and controllers can generate gigabytes of data. If the data can be stored locally until needed for a specific purpose (rather than constantly pushed down to a centralized server and data farm), demand on the network is reduced in step with the lowered security profile of that central server.
