How Blockchain Will Solve Some of IoT's Biggest Security Problems

Blockchain Can Protect Systems and Devices While Supporting IoT Devices that Have Few Security Defenses


While blockchain has its place in the world of cryptocurrency, the growing list of industries considering blockchain initiatives is growing fast including healthcare, telecommunications, energy and even manufacturing.


The reason? Data integrity.


Blockchain is a distributed series of data records, or blocks, linked together as a permanent digital ledger that incorporates transaction information and a timestamp. Once that data is recorded, it can’t be changed or compromised in any way. 


Gartner forecasts that 14.2 billion connected devices will be in use this year, a number that will reach 25 billion by 2021. These devices will produce inconceivable amounts of data — data which needs to be managed and secured.  And while cryptocurrencies are the most popular use case for blockchain today, the immutability of its digital record can open the door to a host of new opportunities in IoT— from supply chain management to cybersecurity.


Driving the Security of the Industrial Supply Chain


Blockchain has huge potential in environments that track and monitor goods via sensor data. Think RFID tags on goods, but instead scanned and written to a blockchain as they go from manufacturer to distributor to retailer. For manufacturers, that means exponentially more visibility, with access to a clear audit trail of who possessed an asset at a distinct point in time.



Car manufacturers, for example, can potentially use blockchain technology to locate and track shipments of auto parts, including their factory of origin and who’s handled the merchandise along the way. In the telecommunications world, blockchain can help operators identify individual connected ..
