Abstract:
Most of the IoT applications are built with the use of centralized servers to process,
transmit and store data. There are risks of single point of failure, mistrust, data
manipulation, tampering and privacy evasion, delay and high operational and
security and efficiency of these applications have become critical concerns.
Integrating Blockchain technology can ensure security and efficiency and solve the
above-mentioned issues in data-centric IoT applications. Many real-life problems can
be solved by IoT-Blockchain solutions. Research was done to find suitable
blockchain mechanisms, Hyperledger Fabric was selected and a model was created
for data-centric IOT applications.
An inadequate number of skilled programmers are able to understand blockchain and
use it. This motivated us to create a system for the developers to easily create
blockchain based data-centric IoT applications with better user experience.
IOT Ledger Creator is a semi-automated tool that gets IOT Data stream attributes
and network configurations from the developer and help to design and deploy
Blockchain applications for data-centric IOT using Hyperledger Fabric. From the
given configurations, necessary configuration files and smart contract will be
generated. Later the blockchain application can be easily deployed with less effort
and time
