“…However, the proposed consensus mechanism may be vulnerable to attacks, and it also results in high block validation time. This paper [20] proposed an idea of deleting the old blocks from each IoT node, this restricts the growth of the blockchain upto some extent. By removing set of blocks from blockchain before which, the XOR of the hashes of those blocks would be stored, which would actually increase the storage capacity of the nodes [20].…”

“…The blocks in the blockchain keep expanding indefinitely, which leads to a gradual increase in the storage space they occupy on devices. However, some devices like traditional desktop computers and IoT devices may not have sufficient memory available to accommodate these growing blocks [20]. Although the utilization of blockchain technology in IoT applications is on the rise for both practical and research purposes, the storage capacity remains a limiting factor [21].…”

The usage of internet and technology inspires the industries to work more on IoT based applications by decentralizing the data storage to ensure data integrity. In such cases, we use blockchain however, with most IoT applications there is always a storage constraint where the IoT devices keep generating the data every few minutes resulting in infinite growth of blockchain that any simple IoT devices would not be able to handle. The idea of deleting old blocks and storing only the recent data by labeling them as expired and unexpired blocks while storing Xor of hashes of deleted set of blocks. Although it resolves some of the issues and attacks, there can be some communication overhead when a node fetches some deleted blocks from other nodes, to validate these blocks, we might need whole set of blocks depending on the set size. Hence arriving at a new idea of adding Xor hash in the block header itself, that resolves the communication overhead along with that full nodes will also be used to always maintain the ledger from the beginning. These ideas will be implemented in an effective way that can be used in real world IoT based applications or any other storage constrained applications
