Kryptomeny - jednoducho a zrozumeteľne
Ak si chceš prečítať len jednu knihu o tomto novom globálnom fenoméne, by mala byť práve táto! Ľudia už od nepamäti snívali o lepšom svete, ako napríklad anglický štátnik Thomas More vo svojom diele Utópia. Dnes, o 500 rokov neskôr, rôzni prognostici spochybňujú prevládajúce spoločenské modely na pozadí vysoko dynamického technologického vývoja a najmä ich vhodnosť pre budúcnosť. Individuálna sloboda verzus nátlak a kontrola zo strany štátu alebo viac osobného pohodlia a ľahší život za cenu straty súkromia? To všetko sú metafory pre základné otázky digitalizácie nášho sveta a spoločného vývoja človeka a stroja. JulianHops nám vo svojej knihe pomáha nahliadnuť do týchto nových možností. Ponúka príležitosť pochopiť základné mechanizmy fungovania kryptoekonómie a rozoznať jej potenciály. Kniha predstavuje podsystém kryptomien a po prvý raz komplexne približuje celej verejnosti celý krytpoekonomický ekosystém. Doposiaľ však nikto neodpovedal na otázku, ako môže svet založený na blockchaine ekologicky udržateľne, respektíve na základe princípov trhového hospodárstva prispieť k súťaži, ktorá podporuje blahobyt.

Großartiges Buch über alle relevanten Punkte im Thema Kryptowährungen. Da ich mich eher als Technik-Noob bezeichnen würde, war es für mich ausschlaggebend, dass ich trotzdem verstehe, worum es sich bei dem Thema dreht. Vorher wusste ich lediglich, dass Kryptowährungen unter bestimmten Umständen als digitales Zahlungsmittel genutzt werden können. Das war‘s dann aber auch schon. Jetzt sehe ich deutlich klarer und dafür danke ich dem Autor.

Oha, wo soll ich anfangen?
Zuerst die negativen Punkte: Hosp versteht es ausgezeichnet, viel Werbung um seine Person und sein Unternehmen zu machen. Damit hält er schon am Anfang nicht hinterm Berg. Das nervt ungemein. Hinzu kommt das Geduze in einem Sachbuch. Schrecklich. Will ich nicht.
Und immer wieder Querverweise zu seiner Firma, so dass der Informationsgehalt diesbezüglich hinterfragt werden muss. Sachlich neutral geht anders. Geht manchmal etwas zu sehr in die Richtung einiger YouTuber à la: ich wurde reich durch blablabla, so schaffst auch du es. :/
Dennoch schaffte JULIAN es, mich soweit zu informieren, dass ich nun zumindest mitreden kann und diese Entwicklung auch weiter verfolgen werde. Spannende Sache das.

A DETAILED EXPLANTION OF HOW CRYPTOCURRENCIES WORK
Author Julian Hosp wrote in the introductory chapter of this 2017 book, “If you have no clue what a blockchain, a cryptocurrency, or Bitcoin is, don’t worry---most of the population doesn’t. If you do, however, would you know how to explain these things in less than a minute to a 10-year-old? Chances are that your answer is ‘no.’ … one starts to wonder how the general public should ever understand these breakthrough concepts [before] they hit the mass market. One of the main challenges for anyone trying to get familiar with the topics around blockchain, decentralization, Bitcoin, and other cryptocurrencies is the question of ‘Where should I start?’ This is exactly what prompted me to write this book [in] the simplest way possible… At the same time, I will reference the details on a technical level to give you both the large scale and the detailed picture.” (Pg.15-16)
He explains, "Decentralization means that everyone who wants to be part of a community or system has the same rights and possibilities. No one is more or less than anyone else. With gold, all financial matters were regulated in a decentralized manner. No one and everyone was in charge, Anyone could go and dig up gold. Anyone was allowed to own it. With fiat money, the central bank of any government is in charge of the financial system. Centralization then took another step forward when money became digitized around the new millennium.” (Pg. 30-31)
He states, “a blockchain is a decentralized community’s complete and unchangeable transaction history that everyone who is part of the community agrees on. This ledger automatically gets updated in regular time frames, is accepted by the community as a fact, and gets stored on every participant’s computer. This way, no central party has to govern the community, since no one can double-spend. That would create an immediate conflict in every participant’s transaction history. Instead of a central party dictating what is ‘reality,’ the community does so in a decentralized manner. Blockchain technology thereby allows storage of any kind of ‘reality’ without needing a governing body. This can be applied to any type of ownership, identification, knowledge, or… currency.”
He notes, ‘Since there is no centralized database where you register; instead of you getting to select an account, you simply receive a random number (called a private key or seed) that is either a string of letters and digits or a set of random words. In the case of Bitcoin, which is the most famous cryptocurrency, you receive a random number out of (2 to the 256th) possibilities. That’s a number followed by 80 zeroes.. The number of account possibilities is insanely large… Normally, this private key is not displayed as the actual number, but in its hexadecimal form with 64 digits/letters… Instead of generating this private key yourself, most of the people in cryptocurrencies let a computer program generate the private key (password) for them. You need your private key to send money, just like you need an e-mail password to log in to your account and send an email.” (Pg. 42)
He states, “Mining is the process of how consensus is created. Consensus is the agreement about how much money is tied to a private key. Basically, how much money is in each participant’s account? In a centralized system as we have with fiat money, a central institution like a bank watches over how much money you have and whether you can actually pay for something or not. In decentralized systems, it works by every participant watching everyone else and then either confirming or rejecting a transaction based on whether you have the money or not.” (Pg. 48)
In answer to his original question, ‘How to explain a blockchain transaction to a 10-year-old?’ he says, “1. In order to make a transaction, you need to prove that you actually own these funds. You do this with your private key. 2. You create a transaction, which we call a puzzle piece. 3. Half of the puzzle piece is the information, who you are sending however many coins. 4. The other half of the puzzle piece is your signature with your key. 5. Both halves make the puzzle piece completely unique. If you changed either half, it would look completely different, become invalid and can only be reproduced by knowing the original information of private key, sender, and receiver. 6. This transaction gets broadcast to the network. While it is impossible to be reproduced by someone without the original info, it is very easy to verify whether the puzzle piece is correct. Is the signature correct? Is the information of ‘from’ and ‘to’ correct? Are the timestamps valid? Etc. 7. Miners pick up the transactions and try to find a block by finding a merkle root that starts with a certain number of zeros. This is called mining… 8. It takes the entire network around 10 minutes in the case of Bitcoin (other blockchains take different amount of times) to solve the puzzle through sheer luck. 9. Once a miner finds a valid block, they broadcast it to everyone, who can then verify the correctness within milliseconds. 10. The puzzle gets ‘fixed’ and is connected to the puzzle from before without being able to be altered. 11. These blocks form a chain and are called a blockchain, which consists of all the transactions ever made. Any new transaction (puzzle piece) starts at step 1. It needs to be connected and checked for its validity within this blockchain so it can be picked up by miners, which is why one needs to know the entire blockchain. History cannot be altered as it would destroy the blocks and thereby the chain.” He adds, “Simple overview, right? A blockchain explained to a 10-year-old.” (Pg. 67-68)
He suggests, “Some people see the maximum limit of a cryptocurrency as the reason why it is better than fiat currencies, which can be inflated by a central authority to infinity. Others see it as the problem, as they call it a deflationary currency, because people will very likely lose their private keys over time and thereby access to the coins, which means the number of circulating bitcoins is decreasing, thereby deflationary. However… both beliefs are incorrect… Obviously, a coin that has a fixed hard cap will appreciate in value way more than when people start using it more, compared to a coin that is constantly inflating. That does NOT mean that Bitcoin will always go up in value, but it is part of the reason why it has done so in the past and will likely do in the future.” (Pg. 72-73)
He explains, “In cryptocurrencies, you CANNOT store coins. Coins are always recorded on the blockchain and never more away from there. You use so-called WALLETS to store the private key that lets you send the coins by signing a cryptographic function on the blockchain… [If] you ever lose a wallet, you don’t necessarily lose your funds. As long as you have written down your private keys somewhere else, you can access them from another wallet anytime.” (Pg. 74)
Is hacking possible? “When people ask this question, they mostly hear about people who have had their private keys stolen through a hacking or phishing attack. You can NOT hack a blockchain, as the cryptography is 100% safe. The biggest problem is improperly storing private keys that leads to people losing access to their coins. Personally, I see the inconvenience of storing private keys as one of the major challenges to cryptocurrencies being mass adopted.” (Pg. 83)
He admits, “[Another] danger that always pops up when talking about cryptocurrencies is that of regulation or even prohibition by a large country or government. The argument makes sense. Since decentralized cryptocurrencies pose a danger to the centralized currencies of such legislations, banks and regulators should have an interest to keep cryptocurrencies suppressed. There is a big flaw in this logic though: Governments LOVE cryptocurrencies… as long as they can control them. Why? Think about what a blockchain as a transparent ledger allows any government to do; if you know who the account holders are, with the click of a button, you can track all incomes, expenses, taxes, etc.” (Pg. 94)
He asserts, “People believe that cryptocurrencies are great for illegal activities… The highest form of privacy possible, however, is cash; no one knows who owns it or who it is given to. That is why governments want to get rid of it. Imagine what this would mean for tax evasion and other crimes. Literally with the press of a button, the revenue department would know all your spending and revenue or law enforcement could instantly see any money laundering or illegal purchases.” (Pg. 101)
He advises, “While I am completely against committing any crimes, I am for a certain amount of intimacy (a level of privacy that most people want to have in their lives) that any individual is entitled to in my opinion. People should be able to pay at a hospital, for example, without the entire rest of the world knowing what the ailment was. Obviously, there is a fine line… If you are freaked out by cryptocurrencies creating a ‘Big Brother,’ don’t worry---there are solutions to that…” (Pg. 102)
He cautions, “At the rate bitcoin has been growing over the past years, it could hit that valuation within 7-10 years. Whether it will or not, no one knows until then. So definitely do NOT take this paragraph as investment advice.” (Pg. 110)
He observes, “What would a currency be used for that is not traceable at all and knows no boundaries? Immediate answers would be drugs, prostitution, money laundering, etc. While some of the criticism might be rectified, one needs not only to keep the problem of fungibility in consideration, but furthermore should ask whether they would want for anyone to know that they were just hospitalized, that they are spending their holidays somewhere, or what they just invested in? So, while lots of privacy has its pros and cons, the magic will be somewhere in the middle. Some anonymity and some transparency are not only okay, but needed…” (Pg. 121)
After listing 14 different types of cryptocurrencies, he admits, “My belief is that most of the coins will probably go to 0 over time, and with that I mean over 99% of them. However, the 1% will not only make up for all the losses, but can actually make you rich. Many times, we have a rising tide, and it appears as if all ideas and coins will be successful… Crypto winter will come at some point. No one knows when and how, so the only thing you can do is to be prepared and don’t fall for shiny objects that actually do not deliver any real value.” (Pg. 133-134)
He admits, “storing cryptocurrencies safely is crucial… One of the worst examples in history was the collapse of MtGox in 2013, where a lot of people lost access to their coins. The solution is to move your cryptocurrencies OFF an exchange as soon as you buy them and you don’t intend on selling them right away.” (Pg. 135-136)
This book hardly makes cryptocurrencies “understandable to a 10-year-old,” but its level of detail will be of great interest to anyone seriously wanting to know how cryptocurrencies actually WORK.

The book covered the intended purpose I thought it would have initially which was to serve as an introduction to cryptocurrencies and the technology allowing their existence - blockchain.
Nonetheless, even though it covered my initial expectations, there were clear elements worth pointing out.
Firstly, my view is that in some cases, the explanation of the concepts could do some improvement. As a book written to the common audience, I understand that the language and concepts had to be conveyed with appropriate language and complexity of ideas. Nonetheless, in some chapters, I felt that either the explanation given wasn't sufficient (there were sub-chapters literally 1 paragraph long) or what I had just read raised more questions (or should I say "unanswered" questions) than it answered.
Additionally, it seemed that this book went over very little scrutiny and editing before being launched. Throughout the book, I found that some images were poorly relatable with the writing while in a myriad of cases I felt more that I was being sold something than reading.
My final assessment is that these lines serve as a good introduction to the topic, despite the downsides.

Quick introduction of Blockchain from a practitioner of blockchain. Dr. Julian Hosp is the founder of Tenx, a blockchain company. The book is short, can be read in one sitting on a weekend. It covers topics from the history of how cryptocurrency as the first killer apps of blockchain appeared, then followed by a few brief technical introductions such as cryptography, private-public key, the mining process, and wallets. There some presentation about altcoins and how altcoins can come, one of it from forking.
I read this after reading many other resources, hence I can quite follow the presentation. However, I don't think one that read only this book can grasp wide areas and topics around blockchain. Nevertheless, it is still a good read on top of additional resources that are coming in this hyped topic.

Ich habe die deutsche Fassung dieses Buches gelesen (5. Auflage 2021) und mein Fazit ist:
Wäre es nach 4 Auflagen nicht mal sinnvoll gewesen, einen (besseren) Lektor einzustellen?
Über den Inhalt will ich mich nicht beschweren - es gibt wenig qualitativ hochwertige, deutsche Literatur zum Thema Kryptowährungen und Julian Hosps Beitrag ist da noch einer der besseren - aber ich kann die unzähligen Fehler einfach nicht akzeptieren.
Was ich in meinen Händen halte, ist die Rohfassung eines Buches, das ganz dringend ein Lektorat oder wenigstens eine Handvoll Korrektur-Leser benötigt!
Beispiel: Seite 51 "genauer gesagt 2256 Stück (eine Zahl beginnend mit 1 gefolgt von achtzig Nullen)"
So etwas muss einem doch beim Korrekturlesen sofort auffallen...

Ich fand das Buch wirklich gewöhnungsbedürftig, nicht wegen dem österreichischen Akzent - den finde ich eher erfrischend - sondern wegen dem umgangssprachlichen und unpräzisen Formulierungsstil. Mir ist da Vorlesen in korrekter und wissenschaftlicher Sprache lieber.
Ansonsten war das Buch eine sehr gute Einführung bzw. Bestätigung meines Wissens der Materie. Es ist sinnvoll strukturiert, verständlich und bewegt sich auf einem guten Abstraktionsniveau.

Great book for beginners
I heard Dr. Hosp on a podcast and appreciated the things he had to say about the crptyo space. I really liked his book and the "Barney" style that he uses to explain the topics plus the geek in me enjoyed the more detailed explanations. I have already started sharing the things I learned.

Great book, very easy to read and understand. Loved how each chapter was divided into sub-questions, super easy to refer back if you need to check something. Gave a great overview and basics into how blockchain works and into cryptos. Warm recommendation if you’re a crypto rookie!

Crypto is a mystery (to me). This book helped greatly in understanding the basic concepts. It's still a mystery, but less so. If you want to know what crypto is and how to manage cryptocurrency, give this a read.

The book is a good starting point. It’s very easy to unterstand and gives a basic and clear overview on the field of cryptocurrency. I only disliked that the book seems sometimes like an ad for his own Startup.

Ich bin bei der Hälfte vom Buch und habe gemischte Gefühle. Manche Erklärungen drin sind schon infantil, wiederum bei anderen Sachen wird gar nichts erklärt. Was ist bspw. Merkle-root? Es wird immer wieder verwendet, wurde jedoch nie erklärt. Auch die Erklärungsweise mit der Puzzlemetaphor ist recht fantasielos und bei einigen Dingen einfach nicht anwendbar. Nach 100 Seiten über Krypto verstehe ich immer noch nicht ob es mehrere Blockchains bei einer Währung gibt, ob nur ein chain berechnet wird und allgemein das ganze Mining ist immer noch sehr unverständlich. Ich denke das Buch ist nicht der beste Einstieg ins Krypto...

unglaublich gut erklärtes & simpel gehaltenes Buch, das mir Einblicke in Kryptowährungen & vor allem in das dezentrale System gegeben hat, was ich wesentlich besser finde als die zentralen staatlichen Institututionen.
