【Abstract】Current node-organizing IoT-based blockchain models lack the scalability and mechanisms needed to accommodate a growing number of nodes while balancing decentralization and node overhead. This study proposes a multi-tiered Self-Scalable Dynamic (SSD) architecture, a new data structure, based on a forest of trees to improve blockchain scalability and efficiency by clustering all nodes, throughout the tiers, limiting those involved in consensus. Our contributions also include: (i) A protocol to accelerate 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 further reduce consensus time. SSD reduces consensus time to 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.
