  Currently, the IoT ecosystem is comprised of fully connected smart devices
that exchange data to provide more automated, precise, and fast decisions. This
idealised situation can only be accomplished if a system for data transactions
is processed efficiently and security is ensured with high scalability and
practicability. The integrity of data must be maintained during the exchange or
transfer of data between entities. We propose to make a application called
DatChain that responds to the above situation. The application stores data
sensed by the Iot sensors in the backend after encrypting it and when the data
is required for any purpose it can be exchanged using a suitable blockchain
network that can keep up with the transfer rate even at high traffic in a
secure environment.
