Briefing

Blockchain scalability limitations hinder widespread adoption, with existing research often fragmented or narrowly focused. This survey introduces a comprehensive analytical framework, deconstructing scalability across architecture, data, and protocols, viewed from both inner-chain and inter-chain perspectives. This integrated understanding provides a roadmap for developing robust, efficient, and truly decentralized blockchain ecosystems capable of meeting future demands.

The composition suggests a dynamic system with elements in motion, particularly the shimmering blue fragments and splashes

Context

Before this research, blockchain scalability studies predominantly focused on isolated aspects, such as single-chain performance or specific cross-chain technologies, without a unified system-level understanding. This fragmented approach left a gap in comprehensively addressing the inherent trade-offs between decentralization, security, and scalability ∞ often termed the “scalability trilemma” ∞ across the entire blockchain ecosystem. The challenge was to synthesize diverse solutions into a coherent framework that could guide holistic advancements.

Intricate, densely packed circuits and luminous data pathways are visible beneath the outer panels, suggesting complex internal operations

Analysis

The paper’s core contribution is a novel, multi-dimensional analytical model for blockchain scalability. It dissects scalability into three primary components ∞ architecture, data, and protocols, each examined through the lens of “inner-chain” (within a single blockchain) and “inter-chain” (across multiple blockchains) solutions. This model provides a holistic framework, departing from previous surveys that often concentrated on specific technologies like sharding or DAGs in isolation.

It systematically categorizes and evaluates existing state-of-the-art solutions ∞ ranging from sharding and sidechains to data pruning and atomic swaps ∞ by mapping them onto this comprehensive structure. This approach reveals how different scaling techniques interact and contribute to the overall system’s capacity, storage efficiency, and transaction processing speed, offering a clearer picture of their collective impact.

Outlook

Future research should focus on optimizing the trade-offs between storage and query costs for inner-chain data, introducing advanced cryptography for inter-chain data security and privacy, and developing non-interactive, multi-party atomic swap protocols to enhance capital liquidity and transaction fairness. The integration of social network knowledge into blockchain design could also yield novel solutions. Over the next 3-5 years, this holistic understanding could unlock truly scalable decentralized finance (DeFi) platforms, efficient supply-chain management systems, and robust cross-chain interoperability, fostering a more interconnected and performant blockchain ecosystem.

This survey fundamentally redefines the understanding of blockchain scalability, providing an essential analytical lens for future architectural and protocol advancements.
