IOTA is *the* DLT (distributed ledger technology) for the Internet of Things.
The facility for distributing telemetry from sensors is called MAM (Masked
Authentication Messaging), for details see their blog.
We were able to transfer dynamically changing MQTT telemetry generated
from our Bosch sensor simulation in our MIMIC MQTT Lab sent to the public
MQTT broker broker.hivemq.com, then through IOTA MAM to the IOTA
tangle in real-time.
You can check it yourself at this online IOTA MAM Explorer, enter this
where it says "enter root-address here...", optionally disable the "Pretty
print (JSON)" button, and press the search button.
This is a proof-of-concept meant to show that you can publish end-to-end
any telemetry from sensors to the IOTA tangle in real-time to be consumed
by your IoT application.
See this in action in this Youtube video.
