Introduction

This book systematically studies blockchain adaptability and scalability, combining theoretical analysis with practical implementation. The book provides a comprehensive exploration of blockchain adaptability and scalability solutions through six chapters.

Chapter 1

Introduces blockchain overviews and current scalability challenges, emphasizing the need for adaptive and scalable blockchains.

Chapter 2

Systematically reviews consensus protocols, from classical BFT to modern PoW, PoS, and sharding approaches, setting the theoretical foundation for subsequent chapters.

Chapter 3

Presents AdaptPoW, which enhances PoW blockchain adaptability and scalability through dynamic structure adjustment and efficient transaction processing.

Chapter 4

Presents AdaptPoS, a PoS-based system with role decoupling and filter mechanism, enabling dynamic throughput adjustment while maintaining security.

Chapter 5

Describes AdaptShard for sharding-based blockchains, including its transaction allocation and optimistic processing strategy for cross-shard transactions.

Chapter 6

Concludes with insights and future research directions.
