Blockchains, Digital Assets, Smart Contracts, Decentralized Autonomous Organizations
In the 1980s, the world entered the computer age, with PCs becoming part of many homes and workplaces. To some people, however, this development was anything but welcome. To them, it seemed to foreshadow the rise of a complete surveillance state, not unlike something out George Orwell’s 1984. So a handful of computer programmers decided to fight back, and their weapon was code.
Thus, in the late eighties, the cypherpunk movement began. Their main aim was the protection of people’s privacy in the digital world.
One of the founders, the American programmer Eric Hughes, cataloged their goals and intentions in the 1993 book A Cypherpunk’s Manifesto. The cypherpunks wished to see safe, encrypted communication in the digital world; this would allow people to make anonymous transactions. Unlike credit card transactions, where the payer and sender can be identified, cypherpunks desired a digital currency where people could send and receive money without being tracked – not unlike paying with cash at the local corner store.
They took the first step toward a private communication system in 1997, by launching the Cypherpunks Distributed Remailer (CDR), which was basically an anonymous, decentralized email system. Not long afterward, came the first version of a cryptocurrency, called b-money, whose invention is credited to an individual with the online handle “Wei Dai.”
Remarkably, b-money worked similarly to how bitcoin works today: all users of the currency held a copy of the transaction log, so that each payment was posted for all to see and potentially approve or dispute. The big difference between b-money and bitcoin is this: in b-money’s day, there was no decentralized way to maintain the accounts.
Nevertheless, other attempts at cryptocurrencies followed, but each died when the dot-com bubble burst around the turn of the century.
Nearly a decade of silence followed. And then, in 2008, bitcoin emerged, becoming the world’s first decentralized digital currency.
Bitcoin’s inventor is known as “Satoshi Nakamoto,” but his real name remains a mystery. However, Nakamoto did make his intentions clear. He wanted to make the concept of a traditional bank – that is, of a central financial institution – obsolete. This is why Bitcoin doesn’t operate on any central registry and why all transactions are made directly between the users.
Now that you know how cryptocurrencies were born, let’s look at how they work.
Ethereum (2016) introduces readers to the world of blockchains, digital currencies and smart contracts, while paying special attention to how the Ethereum cryptocurrency works. It provides a compelling account of where this technology is heading, explaining both how blockchains may revolutionize society and commerce and why Ethereum is currently the most advanced blockchain available.
Blockchains will be to finance what the Internet was to music and video.
Ich bin begeistert. Ich liebe Bücher aber durch zwei kleine Kinder komme ich einfach nicht zum Lesen. Und ja, viele Bücher haben viel bla bla und die Quintessenz ist eigentlich ein Bruchteil.
Genau dafür ist Blinkist total genial! Es wird auf das Wesentliche reduziert, die Blinks sind gut verständlich, gut zusammengefasst und auch hörbar! Das ist super. 80 Euro für ein ganzes Jahr klingt viel, aber dafür unbegrenzt Zugriff auf 3000 Bücher. Und dieses Wissen und die Zeitersparnis ist unbezahlbar.
Extrem empfehlenswert. Statt sinnlos im Facebook zu scrollen höre ich jetzt täglich zwischen 3-4 "Bücher". Bei manchen wird schnelle klar, dass der Kauf unnötig ist, da schon das wichtigste zusammen gefasst wurde..bei anderen macht es Lust doch das Buch selbständig zu lesen. Wirklich toll
Einer der besten, bequemsten und sinnvollsten Apps die auf ein Handy gehören. Jeden morgen 15-20 Minuten für die eigene Weiterbildung/Entwicklung oder Wissen.
Viele tolle Bücher, auf deren Kernaussagen reduziert- präzise und ansprechend zusammengefasst. Endlich habe ich das Gefühl, Zeit für Bücher zu finden, für die ich sonst keine Zeit habe.
Hol dir mit Blinkist die besten Erkenntnisse aus mehr als 7.000 Sachbüchern und Podcasts. In 15 Minuten lesen oder anhören!
