This document proposes decentralizing the Internet of Things using blockchain architecture. It discusses challenges like storing IoT device data and linking communications between devices. The authors propose sending data directly from IoT devices to APIs and then to smart contracts using Oraclize, allowing the smart contracts to store the data on the blockchain. Potential applications include using IoT sensors to monitor pollution levels and track vehicle locations to combat theft. Future work involves practical experiments, applying the approaches to more major applications, and further integrating IoT and blockchain.

2. Overview
 Introduction
 Challenges
 Proposed methods
 Experiment
 Applications
 Future work
 References

3. Introduction
 Blockchain
 Decentralized database
 Distributed or peer to peer network
 Immutable record
 Cryptographic hash functions
 Smart contracts
 IoT aspect
 Protection of information
 Sharable data
 Record maintenance

4. Challenges
 Storing the data of IoT devices
 Local storages, centralized and decentralized clouds
 Sending the data to smart contracts
 The data which is stored should be sent to smart
contracts
 Link communication between IoT devices

5. Proposed method
 Data from IoT devices is
directly sent to API’s
 Retrieve data from API’s
to Smart contracts using
Oraclize technique
Smart contract provides
service to store the data in
Blockchain

6. Other possible method
 Store the data in decentralized
clouds
 Retrieve the data from cloud to
smart contract using Oraclize
technique
Smart contract provides service
to store the data in Blockchain

7. Applications
 IoT devices calculates the
pollution level in the
environment and send data to
Blockchain
 As it maintains permanent
record, industries get alert to
reduce disposing pollutants
into the environment

8. Applications
 For a vehicle service company
owner, it uses to track the location
of their vehicles.
 If their vehicles are stolen by
anyone, we can easily track and find
the victim
 As it maintains permanent record,
we can utilize as proof of stolen.
Victim have no chance to lie.

9. Applications
By using the feature of
permanent record, we can plot
many applications like
monitoring systems in private
and public places like banks,
offices, hospitals, airports, bus
stands, and many other places.

10. Future work
 Practically implementing the experiment
 Apply for all major applications discussed
 Work on consequences
 Explore more on integrating IoT and
Blockchain
