# BIP39 Books — Full Content for LLMs > Consolidated plain-text snapshot of the core pages of bip39books.com. Intended for LLM ingestion and retrieval. Canonical source: https://www.bip39books.com/ Last updated: 2026-04-23 Publisher: RATONGA academy (Ratonga Digital GmbH, Austria) Contact: office@bip39books.com --- ## 1. What BIP39 Books is BIP39 Books publishes real, readable, printed books in which all 2,048 words of the BIP39 English word list appear naturally in the text. Each book therefore doubles as a discreet, non-digital backup tool for a Bitcoin seed phrase — used via the centuries-old Book Cipher method. The book sits on a normal bookshelf or in a normal travel bag and looks like what it is (a children's adventure or a wisdom collection). A short list of page-line-word numbers — the actual backup — is stored somewhere else. Neither piece is useful on its own; together they reconstruct the seed phrase. A BIP39 Book is explicitly an **additional layer** of seed security, not a replacement for metal plates, hardware wallets, or other backups. It offers specific advantages (zero digital footprint, plausible deniability, travel-friendly, low-tech) and has specific limitations (fire, water, physical access) — both books and all site copy position it as one layer in a broader backup strategy. Two books are currently available: 1. **The Adventures of Veit the Fox** — a 104-page children's adventure. Aimed at Bitcoin-holding parents who want to read it aloud to their kids. 2. **777 Wisdoms for Every Day** — a 168-page collection of 777 numbered daily wisdoms. A natural fit for any adult's shelf, nightstand, or travel bag. Both books contain exactly the same 2,048 BIP39 words and work identically as Book Cipher tools. The choice between them is about which fits naturally into your life, not about function. --- ## 2. Homepage (https://www.bip39books.com/) **A book on the shelf. A few numbers on a sheet.** Two pieces. One secure backup. BIP39 Books are real, readable books — each containing all 2,048 BIP39 seed words. Use the ancient Book Cipher method to encode your Bitcoin seed phrase as simple page-line-word references. The numbers stay separate. The book looks like any book on the shelf. Nobody knows what you've protected. - Non-digital - No suspicion - All 2,048 BIP39 words ### Choose Your Book Two books, two audiences — both contain all 2,048 BIP39 words and work the same way. **Veit the Fox** — A children's adventure with all 2,048 BIP39 words. Read it to your kids — while it quietly protects your Bitcoin. Available Now. **777 Wisdoms** — 777 daily wisdoms with all 2,048 BIP39 words. Perfect for your shelf, your nightstand, or your travel bag. Available Now. ### Quick Comparison | | Veit the Fox | 777 Wisdoms | |------------------|---------------------------------|---------------------------------------------------------| | Genre | Children's adventure story | Daily wisdom collection | | Best for | Parents with kids | Anyone — fits any bookshelf | | Pages | 104 | 168 | | BIP39 words | All 2,048 | All 2,048 | | Encoding | page-line-word | page-line-word, wisdom#-line-word, or wisdom#-word | | Double use | Read-aloud bedtime story | Morning ritual / nightstand / gift | | Travel cover | Kids' book in family luggage | Wisdom book in any bag | | Bookstores | Amazon + European retail | Amazon worldwide | Both books work identically as Book Cipher tools. The choice is about which one fits naturally into your life. ### How It Works (summary) The Book Cipher is a centuries-old method. Applied to Bitcoin, it creates a backup with no digital attack surface. 1. **Get the Book.** Choose a BIP39 Book — a real book that contains all 2,048 seed words, woven naturally into its text. 2. **Encode Your Seed.** Find each seed word in the book. Note its page, line, and word position. That's your backup — a short list of numbers. 3. **Store Separately.** Keep the book and the number list in different locations. Neither piece is useful alone. Together, they unlock your seed. ### Gift Not sure what to get someone who holds Bitcoin? A BIP39 Book is useful, original, and something they'd never think to buy themselves. It's a genuine book — not a gadget, not a gimmick — with a purpose they'll genuinely appreciate. Works with any BIP39-compatible wallet: Bitcoin, Ethereum, and dozens of others. > "The best backup is the one nobody knows exists." Your seed phrase encodes your Bitcoin. A BIP39 Book helps you protect it — quietly, elegantly, and without any digital footprint. *Disclaimer: Not financial advice. Using any backup method is done at your own risk. Always maintain multiple backups and verify you can recover your seed phrase.* --- ## 3. How It Works (https://www.bip39books.com/how-it-works/) **How the Book Cipher protects your seed phrase.** Offline, physical, and simple. Two pieces that are worthless apart. - No hardware needed - No digital storage of your backup - Hides in plain sight ### What is a Book Cipher? A method used by spies and diplomats for centuries — now applied to Bitcoin seed backup. The Book Cipher is one of the oldest encryption methods in existence. The idea is simple: instead of writing a secret word, you write a reference to where that word appears in a specific book. The message looks like a list of meaningless numbers — unless you have the exact same book. Spies and diplomats used this method for centuries precisely because the numbers raise no suspicion. A list of numbers could be anything: an inventory, a phone log, a receipt. Without the key book, they are nothing. **Classic example:** Suppose you want to encode the word "meet". You find it on page 47, line 8, word 12 of your shared book. Instead of writing "meet", you write **47-8-12**. To anyone else, it's just a number. To someone with the same book, it's your message. ### How It Works with BIP39 BIP39 seed phrases consist of 12 or 24 words from a fixed list of 2,048 words. BIP39 Books contain all of them. 1. **Get a BIP39 Book.** Your book contains all 2,048 BIP39 seed words, woven naturally into its text. It looks and reads like a regular book. 2. **Find Each Seed Word.** Look up every word of your seed phrase in the book. Use the downloadable word index to find them quickly by page number. 3. **Note the Position.** For each word, write down its page, line, and word number. That three-part reference is your encoded seed word. 4. **Repeat for All Words.** Do this for all 12 or 24 seed words. The result is a compact list of number triplets — your complete backup. 5. **Store Separately.** Keep the book in one place and your number list somewhere else. Together they reconstruct your seed. Apart, they reveal nothing. 6. **Test Your Backup.** Use the numbers and the book to decode your seed phrase and verify it matches. Do this before you rely on it. **Worked Example.** Your first seed word is "abandon". You find it in the book on page 12, line 5, third word on that line. You write: 1. 12-5-3 Repeat for seed words 2 through 24. The result is a numbered list of 24 triplets — compact, innocent-looking, and completely meaningless without the exact book. **777 Wisdoms variant:** That book is organized by wisdom number rather than pages, so positions can also be noted as **wisdom#-line-word** (or just **wisdom#-word**). The principle is identical. ### Why Two Pieces? Security through separation - **Book Alone.** Just a book on a shelf — or in your backpack. No indication of which wallet, which seed, or even that Bitcoin is involved. Anyone who finds it sees a children's story or a collection of wisdoms. - **Numbers Alone.** A list of number triplets with no context. They could be coordinates, phone extensions, product codes — anything. Without the exact book, they cannot be decoded. - **Book + Numbers.** Your complete seed phrase, reconstructed in minutes. This is the only combination that matters — and you control where each piece lives. **Important distinction:** The book is a *tool* for encoding and decoding. It is not the backup itself. Your backup is the number list. The book is how you read it. ### Creative Ways to Store Your Numbers Your encoded seed is just a list of numbers. That gives you enormous flexibility in how you store it — or hide it in plain sight. The goal is something that raises zero suspicion even if found by the wrong person. - **Phone Contact List.** Split the numbers across several fake contacts. "Aunt Martha" has a phone number that is actually your first six seed positions. - **GPS Coordinates.** Format your numbers to look like geographic coordinates. A list of "locations" in a notes app or travel journal. - **Dates and Scores.** Write them as dates, times, sports scores, or reference numbers in a notebook. Completely ordinary in any context. - **Measurements or Codes.** Format as serial numbers, product codes, dimensions, or any other numeric sequence that fits naturally into your life. **Combine with physical durability.** Simple paper works for most people. For additional resilience against fire or water, consider engraving or stamping your numbers onto a metal plate. Metal plates are a complementary option — they protect the durability of your number list, while the Book Cipher protects its meaning. The book itself is a standard printed paperback — multiple copies are easy to obtain, and having a spare on a second shelf in a different location is straightforward. ### Security Best Practices - **Keep book and numbers in separate locations.** This is the core security principle. If both pieces are in the same place, the backup offers no more security than writing your seed phrase on a piece of paper. Different rooms, different buildings, or different cities — the further apart, the better. - **Have a backup copy of the book.** Books can be lost, damaged, or go out of print. Keep a second copy of the book in a different location. Because BIP39 Books are real, published books available on Amazon, obtaining an additional copy is straightforward — but do it before you need it. - **Test your backup before relying on it.** After encoding your seed, decode it again using only your number list and the book. Verify it matches your original seed phrase word for word. A backup you have never tested is a backup you cannot trust. - **Do not use this as your only backup.** The Book Cipher method is an excellent complement to other backup approaches — not a replacement. Maintain at least two independent backup methods. If you lose access to one, the other keeps your Bitcoin safe. - **Tell a trusted person about the system.** A backup that only you understand is a problem if something happens to you. A trusted family member or friend should know that a BIP39 Book exists, where the book is, and that there is a corresponding number list — even if they do not know where the numbers are stored. This ensures your Bitcoin can be recovered by your heirs. --- ## 4. FAQ (https://www.bip39books.com/faq/) ### General **What is BIP39?** BIP39 (Bitcoin Improvement Proposal 39) is an open Bitcoin standard that defines how a wallet seed is represented as a human-readable mnemonic phrase. It specifies a fixed list of exactly 2,048 English words; each word is uniquely identified by its first four letters, which makes the list resistant to typos and ambiguity. Every BIP39-compatible wallet (Ledger, Trezor, BitBox, Sparrow, Electrum, and virtually all modern wallets) can restore a seed from the same mnemonic, which is why BIP39 has become the de-facto interoperability format for Bitcoin and most other cryptocurrency wallets. Because the list is fixed and public, knowing which words it contains — and where they appear in a specific book — makes it possible to encode your entire seed phrase as a short set of position numbers. **What is a Book Cipher?** A Book Cipher is a centuries-old encryption technique that uses a specific book as the shared key between sender and receiver. Instead of storing a secret directly, you record the position of each word within the book — for example, page 42, line 7, word 3. Anyone without the exact book sees only meaningless numbers. BIP39 Books adapt this method for modern Bitcoin seed backup. **How does a Book Cipher protect my seed phrase?** The protection comes from separating the information into two independent pieces. The book alone is just a story — it reveals nothing about your seed. The encoded numbers alone are meaningless without the book. Only someone who has both pieces — and knows how you applied the cipher — can reconstruct your seed phrase. By storing them separately, you eliminate any single point of failure. ### About the Books **What is the difference between Veit the Fox and 777 Wisdoms for Every Day?** Veit the Fox is a children's adventure story aimed at Bitcoin-holding parents. You can read it to your kids while it quietly serves as your seed backup reference. 777 Wisdoms for Every Day is a collection of daily wisdom quotes suited for any adult bookshelf, nightstand, or travel bag. Both books contain all 2,048 BIP39 words and work identically as cipher tools. **Which book should I buy?** If you have children: choose Veit the Fox. It doubles as a genuine read-aloud book and a seed backup reference. If you do not have children or prefer something for daily use: choose 777 Wisdoms for Every Day. Both books work equally well as Book Cipher tools — the choice is purely about which fits your shelf and lifestyle. **Is the book available in my language?** No, both books are published in English only, because the BIP39 standard itself is built around an English word list. The Book Cipher method requires the book to contain exactly the 2,048 words of the BIP39 English word list — the list that virtually every Bitcoin wallet generates and expects by default (Ledger, Trezor, BitBox, Sparrow, Electrum, and most others). BIP39 defines additional word lists in a handful of other languages, but those are rarely enabled in practice and contain an entirely different set of 2,048 words, so building the book around any other language would only work for a small fraction of wallets. The good news: you do not need to read the book fluently to use it as a cipher tool. You only need to locate specific English words at specific page-line-word positions, which works regardless of your English reading level. **Are all 2,048 BIP39 words really in the books?** Yes. Every single one of the 2,048 BIP39 seed words appears in each book, in its exact dictionary form. The words are woven naturally into the text so that the book reads authentically. A downloadable word index is available for each book to help you locate any word quickly. **Can I use both books to encode my seed phrase?** Yes, you can encode your seed phrase with either book or even with both for redundancy. However, the encoded numbers are specific to each book. A reference like 47-3-5 points to a different word in Veit the Fox than in 777 Wisdoms. Numbers created with one book cannot be decoded with the other. Always use the same book for encoding and decoding. **Are the BIP39 words highlighted or marked in the books?** No. The BIP39 words appear naturally within the text without any highlighting, bold formatting, or special markers. The books read like ordinary stories or quote collections. A separate downloadable word index PDF shows you the exact page location of every BIP39 word. ### Security **How safe is the Book Cipher method?** The Book Cipher is only as secure as your operational security. The book alone reveals nothing about your seed. The encoded numbers alone reveal nothing. Only someone who has both pieces — plus knowledge of your encoding format — can decode your seed phrase. Keep the book and the numbers in separate, secure locations and you control the security entirely. **What if someone finds the book?** It looks like a normal book. There are no references to Bitcoin, seed phrases, or cryptocurrency anywhere inside. Words like "seed" or "satoshi" may appear because they are part of the BIP39 word list, but they are used naturally in context. A person who finds the book has no reason to suspect it has any connection to a digital asset backup. **Should a BIP39 Book be my only backup?** No. No single backup method should ever be your only backup. Use a BIP39 Book as one layer in a broader backup strategy alongside other methods such as metal plates or other secure storage. Multiple independent backups stored in multiple locations is the gold standard for seed phrase security. **Can I use a BIP39 Book together with a metal plate?** Yes, and this is an excellent combination. Engrave the encoded numbers (not the seed words themselves) onto a metal plate for fire and flood resistance. A set of numbers engraved on metal is far less recognizable as a Bitcoin backup than 24 English seed words. The book provides the decoding key; the metal plate stores the encoded reference durably. ### Practical **How do I use a BIP39 Book to back up my seed phrase?** Get the book, then use the word index to find the page location of each word in your seed phrase. Note the position (page, line, word number) for each seed word. Store this list of numbers separately from the book. To recover your seed, look up each position in the same edition of the book. See the How It Works page at bip39books.com/how-it-works/ for a full step-by-step guide. **Where can I buy BIP39 Books?** Both books are available on Amazon worldwide. Veit the Fox is also available through major European bookstores including Thalia, Bücher.de, Hugendubel, and Osiander. **Does the edition of the book matter?** Yes. Always use the same print edition consistently. Page numbers can differ between editions, which would make your encoded references unreadable. We recommend keeping a backup copy of the exact same print to ensure long-term consistency. **Is there an eBook version of BIP39 Books?** No, and this is deliberate. A seed backup tool should never exist in digital form. An eBook can be copied, intercepted, indexed, or lost when a device fails. The physical printed book is part of the security model. **What encoding formats can I use with a BIP39 Book?** The most common format is page-line-word (e.g., 42-7-3 means page 42, line 7, word 3). You can also use page-word if you prefer. For 777 Wisdoms for Every Day, you can use wisdom-number-line-word or wisdom-number-word format. You can also disguise the numbers further — formatted as phone numbers, GPS coordinates, or any other innocuous-looking sequence — as long as you remember your own encoding scheme. --- ## 5. Book: The Adventures of Veit the Fox (https://www.bip39books.com/veit-the-fox/) A heartwarming children's story about a young fox on an epic quest to restore a magical crystal. Hidden within its pages: every single one of the 2,048 BIP39 seed words — woven naturally into the story. On your bookshelf, it looks like an ordinary children's book. For you, it's the foundation for a discreet, non-digital Bitcoin seed backup. > "When the light fades, only the brave can bring it back. Follow Veit the Fox on an epic journey across forests, oceans, deserts, and cities as he searches for the pieces of a magical crystal that will restore balance to his world. Along the way, he discovers courage, friendship, and what it truly means to be brave..." ### Why This Book? - **Complete BIP39 Coverage.** All 2,048 seed words appear in their exact dictionary form. Every possible seed phrase can be encoded. - **Real Story, Real Book.** 19 chapters, ~18,000 words. A genuine adventure story that children (and adults) can actually enjoy reading. Ages 6–12. - **Word Index Included.** Downloadable password-protected PDF with the page locations of every BIP39 word. - **Hidden in Plain Sight.** Looks like an innocent children's book. No Bitcoin references anywhere in the text. - **Buy Privately.** Available in physical bookstores across Europe — walk in, pay cash, keep it off the digital record. ### Book Specifications | Property | Details | |----------|---------| | Title | The Adventures of Veit the Fox | | Author | Peter Riegler | | Publisher | RATONGA academy | | Format | Paperback | | Pages | 104 | | Chapters | 19 | | Word Count | ~18,000 | | BIP39 Words | All 2,048 included | | Language | English | | Dimensions | 5×8 in / 127×203 mm (Amazon); 125×190 mm (European retail) | | ISBN (Amazon) | 979-8248013548 | | ISBN (European Retail) | 978-3-8194-2633-9 | | ASIN | B0GPFF7D93 | ### Where to Buy Amazon marketplaces: .com (US), .ca, .co.uk, .ie, .com.au, .de, .fr, .it, .es, .nl, .com.be, .pl, .se, .co.jp — all at ASIN B0GPFF7D93. European retail and online: Thalia (DE/AT), Bücher.de (DE), Hugendubel (DE), Osiander (DE), or any local bookstore via ISBN 978-3-8194-2633-9. ### Security Tips (Veit-specific) - Keep multiple copies in different locations. Two or more copies stored separately protect against fire, flood, theft, or accidental damage. - Store your encoded numbers separately from the book. - This is one method among several — not a replacement for your other backups. Metal plate backups, hardware wallets, and other methods are complementary, not competitors. --- ## 6. Book: 777 Wisdoms for Every Day (https://www.bip39books.com/777-wisdoms/) A genuine book of reflections, provocations, and quiet truths — and secretly, a Book Cipher tool for your Bitcoin seed phrase backup. Every one of the 2,048 BIP39 seed words appears naturally across the 777 numbered wisdoms. On your shelf or in your travel bag, it looks exactly like what it is: a book of wisdom. ### Why 777 Wisdoms? - **Flexible Encoding.** Three reference formats: classic page-line-word, wisdom#-line-word, or wisdom#-word. - **Travel-Friendly.** A wisdom book in luggage draws zero attention. A paperback of quotes and a slip of paper with a few numbers — disguised as a phone number or something equally ordinary — raises no questions anywhere in the world. - **Creative Disguise.** Encoded references are just numbers. Store them as phone numbers, GPS coordinates, dates, or any other format that looks ordinary. - **Pairs With Other Methods.** Works alongside metal seed plates (fire and water resistance) or simple paper. Two-piece security: book alone reveals nothing, numbers alone reveal nothing. - **Zero Digital Footprint.** No servers, no cloud, no malware. Print only — no eBook, deliberately. - **Genuinely Worth Reading.** 777 daily reflections suitable as a morning ritual, nightstand companion, or gift. ### What's Inside Each wisdom is numbered — this is what makes 777 Wisdoms uniquely powerful as a Book Cipher tool. The numbered format gives two additional reference systems: point to a wisdom by its number, then locate the word by line and position (wisdom#-line-word), or simply by word position within the entire wisdom (wisdom#-word). All 2,048 BIP39 seed words appear in their exact dictionary form, woven naturally into the text — no highlighting, no markers, nothing to indicate the book serves any purpose beyond what it claims to be. **Encoding examples:** - page-line-word: `47-3-5` - wisdom#-line-word: `13-2-4` - wisdom#-word: `13-7` - disguised as coordinates: `47°03'05"N 13°02'04"E` **Sample wisdoms:** - #13 — "No perfect moment exists. There is only this one, right now. Use it." (REFLECTIVE) - #42 — "The branch that bends survives the storm. The one that resists it, breaks." (NATURE) - #108 — "Silence is not the absence of thought. It is where thought finally becomes clear." (STILLNESS) ### Book Specifications | Property | Details | |----------|---------| | Title | 777 Wisdoms for Every Day | | Wisdoms | 777 numbered wisdoms | | Pages | 168 | | BIP39 Words | All 2,048 included | | Format | Paperback (print only — no eBook) | | Language | English | | Publisher | RATONGA® academy | | ISBN | 979-8254568834 | | ASIN | B0GVRX56VZ | ### Where to Buy Amazon marketplaces: .com (US), .ca, .co.uk, .ie, .com.au, .de, .fr, .it, .es, .nl, .com.be, .pl, .se, .co.jp — all at ASIN B0GVRX56VZ. --- ## 7. About (https://www.bip39books.com/about/) BIP39 Books is published by **RATONGA academy**, the imprint of Ratonga Digital GmbH, an Austrian company.

Key disclaimers (site-wide) - **Not financial advice.** The information on bip39books.com is for educational and informational purposes only. No investment, legal, or tax advice is provided. - **Use at your own risk.** Using any backup method — including a Book Cipher — is done entirely at the user's own risk. The author, publisher, and website operators assume no responsibility for any loss, damage, or theft of funds or information. - **Always maintain multiple independent backups.** A BIP39 Book is one layer in a broader backup strategy — not the only backup. - **Always verify recovery.** Test decoding before relying on the backup. --- ## 9. What NOT to assume - **The book is not the backup.** The book is a *tool* for encoding and decoding. The actual backup is the short list of numbers the user writes down and stores separately. - **Book Cipher does not replace other methods.** It complements metal plates, hardware wallets, and other storage — it does not replace them. - **Not only for Bitcoin.** Any wallet using the BIP39 English word list works: most Bitcoin wallets, plus Ethereum and dozens of other cryptocurrencies. - **Not a children's-market product.** Veit the Fox is marketed to *Bitcoin-holding parents*, not to general children's-book buyers. The cipher use case is the reason it exists. - **Not a language-flexibility project.** The books are English-only by technical necessity: BIP39 is defined on a fixed English word list that virtually all wallets use. Other-language variants would not serve their users.
