“…Transaction Timestamps are used to enable data auditing, while blocks are chained in a Merkle tree [3], [4] structure to prevent data tampering. Due to its salient characteristics, blockchain technology has been considered for large-scale distributed networks, notably the Internet of Things (IoT) [5]. Nevertheless, BC nodes often take considerable time to reach consensus due to the complexity of computations and the large number of hops required for transactions and blocks to reach participating nodes.…”

Many node-organizing blockchain models for IoT lack the scalability needed for high transaction volumes and mechanisms to manage decentralization and node overhead. This study proposes a multi-tiered Self-Scalable Dynamic architecture based on a forest of trees to improve scalability and efficiency by clustering all nodes to limit those involved in consensus. In addition to the architecture, our contributions include: i) A protocol to speed up consensus. ii) A mechanism for efficient node-lookup and message-routing. iii) A dynamic algorithm to balance overhead and decentralization. iv) A colocality mechanism to enhance consensus time. This architecture reduces consensus time with an upper bound of O(1) plus a propagation delay factor. As more IoT devices join, resulting in a deeper forest, the model becomes more scalable with shorter consensus delays. The proposed mechanisms may serve as general-purpose solutions for scalability, load balancing, node-lookup and message-routing, and are application-, clustering-, and consensus-algorithm-agnostic.
