SpringerBriefs in Computer Science Blockchain Without Barriers

We present the novel, modular Cross-Domain Trust Mesh (CDTM) for governance-aware systems that are safe, compatible, and decomposable. This book is intended for scholars, researchers, developers, and inquisitive learners. Do you want to convert Bitcoins to Ether? Are you interested in transferring a digital land asset on the HyperLedger? Do you wish to trade NFTs across multiple blockchains? Extensive research has led to the development of numerous interoperability protocols and procedures that allow different blockchains to function together effortlessly. Examples that support it include LayerZero ULN, Polkadot XCM, Cosmos IBC, and Chainlink CCIP. We present a thorough assessment of the literature. Attacks like Wormhole and Nomad, which cost millions of dollars, were caused by vulnerabilities in these platforms. In order to modify and enhance these technologies, this book offers a developer guide on how to simulate them on your desktop. After reading this book, you may use detailed code walkthroughs to replicate bridges, relayers, and event-driven contracts in Truffle, Ganache, and Solidity. We present the novel, modular Cross-Domain Trust Mesh (CDTM) for governance-aware systems that are safe, compatible, and decomposable. Replay protection, compliance, Oracle manipulation, and developer abstractions are covered. By establishing clear standards for further study, we create the groundwork for Web3.0, a genuinely decentralized, interoperable world. This book is intended for scholars, researchers, developers, and inquisitive learners.
