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. Presents a comprehensive progression of blockchain scaling solutions at the consensus layer; Introduces three novel adaptive scaling blockchain approaches: AdaptPoW, AdaptPoS, and AdaptShard; Bridges theoretical analysis with practical applications through extensive real-world implementations and evaluations. 410 0$aWireless Networks,$x2366-1445 606 $aTelecommunication 606 $aCooperating objects (Computer systems) 606 $aBlockchains (Databases) 606 $aCommunications Engineering, Networks 606 $aCyber-Physical Systems 606 $aBlockchain 615 0$aTelecommunication. 615 0$aCooperating objects (Computer systems) 615 0$aBlockchains (Databases) 615 14$aCommunications Engineering, Networks. 615 24$aCyber-Physical Systems. 615 24$aBlockchain. 676 $a621.382 700 $aXu$b Jie$01249742 701 $aJia$b Xiaohua$0885801 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911015969103321 996 $aAdaptive and Scalable Blockchain Systems$94410002 997 $aUNINA
