A Technical Guide to Distributed Ledger Technology and Blockchain

A Technical Guide to Distributed Ledger Technology and Blockchain cuts through common misconceptions surrounding distributed ledger technology (DLT) by delivering a precise account of how blockchain systems actually function beneath the buzzwords. Grounded in academic research and university instruction, the text demystifies public payment networks, programmable smart-contract platforms, and private enterprise infrastructures. Readers will gain the technical vocabulary and critical architectural insight needed to distinguish permissionless networks from permissioned policy-driven ledgers and evaluate when a blockchain is the appropriate tool for a given system.

Drawing on the research and hands-on experience of the authors, this book builds up from the foundations of cryptography, covering digital signatures, cryptographic hashing, and public key encryption, before advancing into the architectures of Bitcoin, Ethereum, and Hyperledger Fabric. This resource draws a contrast between the economic consensus mechanisms of public chains with identity-driven trust models in enterprise environments. It further details how self-sovereign identity (SSI), decentralized identifiers (DIDs), verifiable credentials, and the InterPlanetary File System (IPFS), complement blockchain systems by handling portable identity layers and off-chain data storage.

This guide serves as a practical reference for technical students, researchers, and software engineers seeking a grounded understanding of decentralized infrastructure . Visual diagrams and comparative tables break down complex cryptographic processes into clear reference models, making dense concepts easily navigable. By focusing on core architectural principles rather than temporary platform trends, the volume provides lasting reference value for analyzing present and future distributed systems. Like a record on a distributed ledger, this book commits its knowledge once and remains immutable.
