Our contribution This work introduces a novel approach to optimizing tree-based data structures within blockchain technology, focusing on adaptive restructuring techniques for Merkle and Verkle Trees. Our contributions are twofold: First, we propose a dynamic restructuring algorithm that enhances the scalability and efficiency of blockchain systems by optimizing the verification and storage processes. Second, we extend the applicability of these optimized tree structures beyond traditional blockchain applications, demonstrating their versatility in various blockchain architectures and scenarios. Through rigorous analysis and experimentation, our research addresses the critical scalability challenges faced by blockchain technology, offering a scalable, efficient, and adaptable solution. 1.4. Article structure The structure of this article is designed to provide a comprehensive overview of our research and findings. Section 2 conceptualizes the problem of blockchain scalability and the role of tree-based data structures in addressing this challenge. Section 3 introduces our idea for optimizing trees in blockchain, detailing the theoretical foundation of our approach. Section 4 evaluates the efficiency of adaptive Merkle trees through analytical and empirical methods. Section 5 describes the algorithm for Merkle Tree restructuring, followed by Section 6, which presents examples of the algorithm's execution in various scenarios. Section 7 delves into the specifics of path encoding in adaptive Merkle Trees, and Section 8 explores the enhancement of Verkle Trees through adaptive restructuring. The discussion in Section 9 synthesizes our results, comparing them with existing solutions and highlighting our contribution to the field. Finally, the conclusion in Section 10 summarizes our research contributions and outlines future directions for this promising area of study.
