摘要

Blockchain technologies have revolutionized numerous industries by providing decentralized, transparent, and immutable systems. Despite significant benefits, scalability, privacy, interoperability, and regulatory compliance pose major challenges. This review explores recent advancements in blockchain protocols, focusing on innovative approaches to scalability and transaction management, as seen in works such as SChain [1]. We also discuss decentralized finance (DeFi) challenges and solutions for enhancing blockchain interoperability, such as cross-chain transactions [2], sharding optimizations [3], and novel consensus mechanisms [4]. The paper highlights the need for continuous innovation to ensure that blockchain systems can scale efficiently and comply with evolving regulations.
