Born as a natural evolution of my first manual (Bitcoin: dalla teoria alla pratica), in this book I condensed the study of the protocol into a Q&A framework divided by difficulty levels. The goal was to simplify cryptography and network architecture concepts into concise and technically rigorous answers.
The advanced topics covered include:
- Cryptographic Foundations: Practical application of the SHA-256 algorithm, digital signatures with elliptic curves (ECDSA/ECC), and asymmetric cryptography.
- Data Structures & Architecture: Hashing mechanisms for blocks and transactions (SigHash), Big/Little Endian conversion, and structural management of the Blockchain.
- UTXO Model & Transactions: In-depth analysis of Unspent Transaction Outputs, dynamic fee calculation, input/output management, and the native transaction (Coinbase).
- Distributed Systems & Consensus: Study of the Byzantine Generals Problem, Proof of Work, difficulty adjustment, and Fork resolution (Soft/Hard).
Writing this book allowed me to significantly refine my Technical Writing skills: translating complex architectural concepts and low-level cryptography into accessible and structured documentation.
