IoT + Blockchain
Decentralization
Telemetry becomes transactions
Data are collected and turned into immutable
Decisions are transparently traced
We build extra confidence for data-driven organizations

How to add Blockchain to the IoT Ecosystems
There are two main strategies to add Blockchain to IOT: embed Blockchain nodes in the IoT components
or enable them to send the data to the nodes in a secure and reliable way

What do we need to usually see
blockchain of things?
Make accessible for everyone to connect with
Blockchain capabilities
Make as easy to deploy a new IoT device that collects
data and record it on any blockchain must be as easy
as it is today to connect it to your favorite IoT Cloud
