A book by Alessio Barnini and Alessandro Aglietti in a brief question-and-answer format about Bitcoin. This overview draws on the public introduction, table of contents and statements by the authors, rather than a reading of all the answers.
Bitcoin: 199 Questions was written by Alessio Barnini and Alessandro Aglietti. The English paperback edition is listed as published on 5 July 2019, with 74 pages and ISBN 9781078155588. The year 2019 also matches the copyright in the public sample. These details identify a specific edition, not the date when its individual answers were last updated. [2]
In an interview published in December 2019, the authors describe the development of their educational project: from a video course and its scripts to the longer book Bitcoin: from theory to practice, followed by the pocket question-and-answer format. The shorter title was intended to make basic and advanced concepts accessible to a wider audience. We attribute this history to the authors; we did not verify their course by completing it in practice. [3]
The introduction and the authors’ page promise answers in a few lines, while explicitly acknowledging that some technical questions require more detailed explanation. They therefore refer readers to the longer companion book. Readers should distinguish a quick introduction to a concept from understanding all its connections or safely carrying out a specific procedure. [1] [2]
The published table of contents uses the sections Entry Level, Intermediate Level, Advanced Level and Nerd Zone. It progresses from basic questions to protocol details. This is a documented map of topics; question titles alone do not establish the completeness or accuracy of their answers. In this overview, we therefore do not infer from the contents that we have verified every explanation inside the book. [2]
The opening and middle sections of the table of contents list questions about wallet types, private keys, backups, fees and transaction confirmations. This sequence offers readers a useful outline for further study. Here, however, we summarize topics from the contents rather than the unavailable answers, and we do not assess the book as a verified guide to handling real funds. [2]
Later sections of the table of contents mention digital signatures, UTXO, scripts, Merkle Tree, key derivation and test networks. Readers can mark unfamiliar concepts and explore their connections in further documentation. A question title alone does not reveal which assumptions or exceptions its answer explains; without the main text, we did not assess these. [2]
The interview also records the authors’ expectations at the time about Bitcoin’s development. These statements belong to their historical context; we do not present them as the current state of the network or a guaranteed forecast. For further reading, we recommend separating a general concept from a claim dependent on a particular software version and consulting current primary documentation. [3]
We read the entire published introduction on printed pages 10–11 and the entire available table of contents on pages 4–9 in the sample of the English edition. We viewed the cover, title and copyright pages, the closing photograph and the back cover. We read the authors’ product page and the entire published interview. The sample omits the main answers; we did not read the whole book or carry out its procedures. [1] [2] [3]
For the clearest picture, read this entry together with Bitcoin, Transaction, Mining, Wallet.
01Is this an assessment of every answer in the book?+
No. The public sample provided the introduction and table of contents but omits the main answers. This overview therefore documents the book’s focus and structure; it does not pretend to check every answer or to reflect a complete reading.
02Does the pocket format replace a detailed technical course?+
In the introduction, the authors themselves acknowledge that some questions need longer explanations and refer to a companion book. The brief format can serve as an outline for further study; we did not verify its procedures by carrying them out.
