This is the discussion materials prepared for the Internet of Things and Blockchain session led by Dr. Steve Liang. The IoT and blockchain session is part of the Blockchain and Cryptocurrency Workshop - PST 2017, Calgary, Canada. In this session Dr. Steve Liang discussed several IoT projects and the possible blockchain-based approaches to deal with the authenticity of sensor data and smart contracts.

2. Question
• Is there a systematic way to
apply blockchain to certain
applications? or to evaluate
blockchain for certain
applications?

3. IoT information for blockchain?
• Device ID
• Device metadata
• Observations collected by devices
• Intended applications
• Users of the observations

4. Let’s try… a technology push
method…
Let’s review some IoT solutions, and see how can
we fit blockchain into them? Is blockchain going to
offer value? or even disrupt the existing approaches?
(I know pull is always better than push…but this
might provide us a different view on blockchain for
IoT.)

7. Question:
how can blockchain be
applied to the next
generation first
responders?

8. Idea:
using permission-based blockchain as
a secure distributed web service
catalog to prevent data tampering (in
this case the endpoints of IoT data
services) and man-in-the-middle
attack.

9. Smart Citizens

10. Expanding to 500 sensors across 10
Canadian cities
•Jul 08 - St. Albert
•Sep - Winnipeg
•Sep - Ottawa
•Oct, Edmonton
•Oct/Nov, Toronto

11. Question:
how can blockchain be
applied to large-scale
crowd sensing
systems?

12. Idea:
using blockchain to store IoT
observation data and metadata to
ensure data are not tampered.

13. CloudUAV

15. Question:
UAV Compliance is
one of the most pressing
issue. How can we apply
blockchain here?

16. Idea:
using blockchain to manage UAV flight
mission data (e.g., flight plan, flight
path, telemetry data) to ensure
compliance.
