Data Storage in Blockchain Based Architectures for Internet of Things (IoT)


Data storage in IoT systems describe how data is pushed from the sensor and where it will be stored. In Bitcoin, there is a limit to the number of transactions that can be stored in the block, similarly in Ethereum it is limited by the gas limit in block. An IoT infrastructure have several applications that includes a sensor collecting data from physical environment. Storing a large amount data in a blockchain faces several challenges due to the distributed nature of the blockchain, high transaction processing time, and reduced scalability. Hence it is crucial to identify what data should be stored and how to store it in a secure way. In this paper, we provide how data is being stored in various blockchain based IoT applications and provides data storage compliance in treating IoT data in a blockchain environment.
