(Axon & Goldsmith, 2016)

To control IoT apps, this leverages a Blockchain-based Public-Key

Infrastructure (PKI). They used smart contracts-based Blockchain addresses,

which provided commands to the IoT devices. Such commands vary from

modifying operating practices to storing data on energy usage on the

Blockchain.

The research presents a model of a smart city based on a Blockchain

technology for maintaining the discretion and concealment of scrambled

information by the fundamental immutableness of the Blockchain. The

suggested approach uses the Blockchain based on Ethereum with smart

contracts for the determination of functionality.
