Title:
IGD-ScoreChain: A novel Lightweight-Scalable Blockchain based on nodes sharding for the Internet of Things
Authors: Elnaz Mehraein, Zahra Ahmadian, Reza Nourmohammadi
Abstract:Due to the significant development of the intelligence industry worldwide, various initiatives have increasingly recognized the value of the Internet of Things. IoT systems, however, are often hindered by fundamental challenges, such as the need for a central server to manage them. Decentralizing these systems can be achieved through the use of blockchains. Recently, there has been an increase in the popularity of blockchain in various fields, such as banking, Internet of Things, and intelligence industry, and human societies have taken notice of it. One of the main problems is with the scalability of such systems as the network size grows.
This paper examines how blockchain can assist IoT systems to overcome this challenge. We introduce a lightweight-scalable blockchain as a solution for the sharding nodes. This solution assigns nodes to shards according to their history of activity. As part of this study, an IGDBFT algorithm is introduced within the proposed scheme for intra-shard consensus. A solution to storing blocks and cross-shard transactions has been developed using a global chain containing parent blocks in the cloud layer. Finally, we analyze the security and efficiency of our scheme and compare our sharding-based protocol with previous protocols.
