Abstract
A centralized IoT network has a problem of data centralization because data is stored in a center. A blockchain is emerging as a solution to solve the problem in the IoT network by storing blocks to each device. However, lightweight IoT devices cannot store all of the blockchain due to their low storage capacity. We propose storage compression consensus (SCC) algorithm which compresses a blockchain in each device to ensure the storage capacity. When a lightweight device does not have enough storage space, the device processes the SCC to compress the blockchain. We implemented simulations to compare between the SCC and the existing consensus algorithm. As a result, the proposed SCC reduced the storage capacity of stored blockchain by 63% compared to the existing algorithm.Keywords
