Layer Solutions by Mia Wright

"Layer Solutions" tackles the pressing issue of blockchain scalability, essential for the widespread adoption of decentralized applications.
Highlighting how Layer 2 protocols, sidechains, and sharding can overcome limitations in transaction speed and efficiency, the book argues these technologies are vital, not just incremental improvements.
For example, the book explores how sidechains offer independent blockchains linked to the main chain, and how sharding divides the blockchain into smaller, manageable pieces.

The book progresses logically, starting with the limitations of current blockchain architectures and then diving into Layer 2 protocols like payment and state channels as well as rollups.
Later chapters examine sidechains and sharding, dissecting their complexities and addressing challenges such as cross-shard communication.

By exploring implementations across industries like finance and supply chain management, "Layer Solutions" provides valuable insights into the practical applications and trade-offs of each approach, combining cryptoeconomics and network engineering to provide a complete picture.
