Abstract

Internet of Things (IoT) research is in full swing to integrate recent technologies such as the blockchain to enhance system security. However, the blockchain faces many limitations, such as resource demands, energy requirements, scalability, and high latency. This article presents a novel post-blockchain structure that integrates a multi-blockchain in one ledger using a directed acyclic graph (DAG) structure called a multi-chain. The multi-chain structure resolves the issues of scalability and storage and is a candidate to replace the traditional blockchain in IoT applications. This article also introduces a new consensus algorithm called 'Multi-Chain Proof of Rapid Authentication' (McPoRA) to improve latency, which is a crucial factor in IoT resource constrained devices. McPoRA is approx. 4000X faster than proof-of-work (PoW) and 55X faster than Proof-of-Authentication (PoAh).
