Blockchain? Das hat doch was mit Bitcoins und Kryptowährungen zu tun – oder? Aber was genau ist die Blockchain eigentlich und wozu ist sie gut? Das erklären wir in diesem animade Erklärfilm. youknow ist einer der führenden Anbieter von Erklärvideos und E-Learning-Lösungen im deutschsprachigen Raum. Weitere Infos auf 🤍, 🤍 und 🤍. Du darfst dieses Erklärvideo gerne für eigene Zwecke verwenden. Voraussetzung ist, dass du uns namentlich nennst (youknow) und auf unsere Website verlinkst (🤍). Blockchain? Das hat doch was mit Bitcoins zu tun! Oder? Aber was genau hat es mit der Blockchain auf sich? Um das Prinzip einer Blockchain zu verstehen, hilft der Vergleich mit einem Gruppenchat: Ben, Lisa und Mia haben sich um 14 Uhr im Park verabredet. Diese Information ist nach dem Absenden auf jedem Handy im Chatverlauf gespeichert. Mia überlegt es sich anders und möchte sich erst um 16 Uhr treffen? Diese Entscheidung kann sie nicht alleine fällen. Sie kann auch nicht einfach die Uhrzeit im Chatverlauf nachträglich ändern. Mia muss also entweder gemeinsam mit den anderen von vorne planen, oder sie steht um 16 Uhr alleine im Park. Niemand kann nachträglich etwas verändern – dieses Prinzip ist der Kern einer Blockchain: Auch hier werden Informationen in einem Verlauf gespeichert. Jede Information bildet einen Block. Für diesen wird ein Hash, also eine Art digitaler Fingerabdruck, berechnet und er enthält zusätzlich auch den Hash des vorherigen Blocks. Über die Hashes werden die Blöcke miteinander zu einer Kette verbunden. Ähnlich wie bei einem Chatverlauf können Informationen nicht verändert werden. Denn ändert sich eine Information, ändert sich auch ihr Hash und die Kette würde auseinanderbrechen. Genau wie Mia und ihre Freunde mit der Planung von vorne beginnen müssten, müssten die Hashes aller folgenden Blöcke neu berechnet werden. Im Chat ist das kein Problem. Bei einer Blockchain ist das nicht so einfach. Sie wird über ein dezentrales Netzwerk verwaltet, dem jeder beitreten kann. Jedes Mitglied hat eine vollständige Kopie der kompletten Blockchain auf dem Computer und dieser prüft, ob sie noch intakt ist. Ein neuer Block wird erst hinzugefügt, wenn ihn jeder Computer im Netzwerk verifiziert hat. Das macht eine Blockchain so sicher. Jeder kontrolliert jeden – wichtig ist dafür aber nicht der Mensch vor dem Computer oder eine dritte Instanz, wie beispielsweise ein Notar: Die Kontrolle und somit das Vertrauen werden von der Blockchain technisch hergestellt. Und was hat das nun mit Bitcoins zu tun? Nun, die Blockchain ist die Technologie, Kryptowährungen sind nur eine Anwendungsmöglichkeit. Mit ihr lässt sich aber noch viel mehr machen: von der dezentralen Speicherung von Patientendaten, über die lückenlose Dokumentation von Lieferketten, bis hin zu sicheren Wahlen. Alles klar? Dann können sich unsere Freunde endlich im Park treffen. Aber wo bleibt Mia? Quellen: 🤍 🤍 🤍 🤍 🤍 🤍 🤍 🤍 🤍 🤍 🤍 🤍 🤍 🤍 🤍 🤍 🤍 🤍

What is BLOCKCHAIN? The best explanation of blockchain technology

Blockchain explained in plain English Understanding how blockchain works and identifying myths about its powers are the first steps to developing blockchain technologies. Blockchain is an algorithm and distributed data structure for managing electronic cash without a central administrator among people who know nothing about one another. Originally designed for the crypto-currency Bitcoin, the blockchain architecture was driven by a radical rejection of at (government-guaranteed) money and bank-controlled payments. Blockchain is a special instance of Distributed Ledger Technologies (DLTs), almost all of which have emerged in Bitcoin's wake. HOW DOES BLOCKCHAIN WORK? Blockchain is a Distributed Ledger Technology (DLT) that was invented to support the Bitcoin cryptocurrency. Bitcoin was motivated by an extreme rejection of government-guaranteed money and bank-controlled payments. The developer of Bitcoin, Satoshi Nakamoto envisioned people spending money without friction, intermediaries, regulation or the need to know or trust other parties. Technically, the original blockchain is separable from Bitcoin, but this report will show that the blockchain design is so specific to Bitcoin that it's not a good fit for much else. The central problem in electronic cash is Double Spend. Because pure electronic money is just data, nothing stops a currency holder from trying to spend it twice. Blockchain solves the Double Spend problem without a digital reserve fund or similar form of umpire. Blockchain monitors and verifies Bitcoin transactions by calling upon a decentralized network of volunteer-run nodes to, in effect, vote on the order in which transactions occur. The network's algorithm ensures that each transaction is unique. Video created by the Centre of International Governance Innovation.

The true power and potential of blockchain is incredible. This is way more impactful than the power of any social media platform or digital-born business like Uber, the blockchain can actually change the fundamental structure of society, and not everyone is necessarily going to be happy about it. There is a lot of good to come from blockchain technology and cryptocurrencies, but there are plenty of entities who are in control now that would lose their power if blockchains were to become part of everyday life. Be aware of these things as you are navigating the space and always keep in mind the long term consequences this technology can have on how the world operates. — ► Check out my main YouTube channel here: 🤍 — Gary Vaynerchuk is a serial entrepreneur and the Chairman of VaynerX, a modern day communications parent company, as well as the CEO and Co-Founder of VaynerMedia, a full-service digital agency servicing Fortune 500 clients across the company’s 4 locations.

While I was modeling in Hong Kong, I eventually felt the desire to further my education. I decided to depart the modeling world and move back to Canada, knowing that could be the end of my modeling opportunities. I attended Ryerson University for GCM (Graphic Communications Management), as I thought I might still work in the fashion industry in another capacity. It was in my last year of university, I was introduced to a very basic coding course. I instantly fell in love. From there I knew I wanted to pursue software development but didn't have a clue where to start. I didn't want to go back to university as I just completed a four-year degree. I decided to enroll in a 10-week intensive coding Bootcamp. From there I started working at a small startup learning and growing my technical and soft skills. I then transitioned to a larger company where I am a software developer and technical consultant today. How To Become a Blockchain Developer in 2022? #BlockchainDeveloper #TiffInTech

Some crypto enthusiasts want a new kind of internet that yanks power away from Big Tech and hands it to people. Can they succeed? Remember AOL chatrooms and downloading songs through Napster? The internet has come a long way. Today, it’s dominated by Meta, Google and a handful of other tech giants whose services have made it easier for billions of people to communicate and share content online. But at what cost? “If something is free, you are the product,” so the saying goes — the only reason platforms like Facebook and YouTube can offer their services for free is because they use our personal data to target us with ads. “Right now, you have big organizations who are controlling your data and providing you services that use your data,” says Bertrand Perez, chief operating officer of the Web3 Foundation. Web3 is a hypothetical, future version of the net based on blockchain technology. Crypto enthusiasts say their vision for the web would decentralize it, pushing it closer to its roots. But big-name detractors — from Jack Dorsey to Elon Musk — aren’t convinced. Watch the video to learn more about Web3 — what it is, and what its future may be. #CNBC #Web3 #Blockchain - Subscribe: 🤍 CNBC International TV: 🤍 Facebook: 🤍 Instagram: 🤍 Twitter: 🤍

"Wir und die Blockchain" AKA "The Blockchain And Us": Filmregisseur Manuel Stagars porträtiert die Versprechungen von Blockchain-Technologie in neunzehn Interviews mit Softwareentwicklern, Kryptografen, Wissenschaftern, Unternehmern, Beratern, Investoren, Buchautoren, Politikern und Zukunftsforschern aus den U.S.A., Kanada, der Schweiz, England und Australien. Wie könnte die Blockchain-Technologie unser Leben und Zusammenleben verändern? Manuel Stagars geht dieser Frage in seinem Film "Wir und die Blockchain" nach. Sein Beitrag spinnt einige der Hauptaussagen aus dem Film weiter. Regie: Manuel Stagars Hauptdarsteller: Alex Tapscott, Manuel Stagars, Dave Birch Als die Gebrüder Wright 1903 das Flugzeug erfanden, konnte man sich kaum vorstellen, dass heute zu jedem Zeitpunkt mehr als 500.000 Menschen in der Luft unterwegs sein würden. Im Jahr 2008 erfand Satoshi Nakamoto den Bitcoin und die Blockchain. Seine Erfindung machte es zum ersten Mal in der Geschichte möglich, Geld ohne Banken, Regierungen oder andere Vermittler rund um den Globus zu schicken. Satoshi ist eine geheimnisvolle Figur, und genau wie die Gebrüder Wright hat er ein unlösbares Problem gelöst. Das Konzept der Blockchain ist nicht sehr intuitiv. Dennoch glauben viele Menschen, dass es ein Game Changer ist. Trotz ihrer mysteriösen Anfänge könnte die Blockchain das Flugzeug unserer Zeit sein. Manuel Stagars porträtiert diese spannende Technologie in Interviews mit Softwareentwicklern, Kryptologen, Forschern, Unternehmern, Beratern, VCs, Autoren, Politikern und Futuristen aus den USA, Kanada, der Schweiz, Großbritannien und Australien. Wie kann die Blockchain den Volkswirtschaften der Nationen nützen? Wie wird sie die Gesellschaft verändern? Was bedeutet das für jeden von uns? The Blockchain and Us erklärt nicht die Technologie, sondern startet eine Konversation über ihre potenziellen, weitreichenden Auswirkungen. Der Film wirft bewusst mehr Fragen auf, als er beantwortet. Für einen tieferen Einblick, sehen Sie alle Interviews in voller Länge aus dem Film-Stream auf der offiziellen Website des Films. ✘ Website - 🤍 #bitcoin #kryptowährung #blockchain COPYRIGHT: All of the films published by us are legally licensed.

Cryptopia | Web 3.0 | Future of the Internet | Bitcoin Documentary | Blockchain

Do you suffer from Crypto Confusion? Then this entertaining and educating documentary is for you! It has won more than a dozen awards at international film festivals. Five years after his first Bitcoin documentary, award-winning producer/director Torsten Hoffmann revisits the topic and sets out to explore the evolution of the blockchain industry and its new lofty promises. Can this technology, designed to operate independent of trust and within a decentralized network, really provide a robust alternative to the Internet as we know it (web3.0)? Cryptopia (2020) Director: Torsten Hoffmann, Michael Watchulonis Writer: Torsten Hoffmann Stars: Andreas M. Antonopoulos, Vitalik Buterin, Laura Shin, Roger Ver, Torsten Hoffmann Genre: Documentary Country: Australia, United States, Germany Language: English, German Also Known As: Cryptopia: Bitcoin, Blockchains and the Future of the Internet Release Date: 14 January 2020 (Australia) Duration: 86 min Filming Locations: Australia, United States, Germany, United Kingdom, Switzerland, Japan, Hong Kong Storyline: Bitcoin has been called one of the most disruptive technologies of our times, threatening banks by building an alternative and decentralized currency system. Some say that its "blockchain" could provide a blueprint for a better and fairer Internet - challenging the dominating technology giants. Despite this potential, Bitcoin is undergoing severe price volatility and the community is facing a bitter internal 'civil war'. Moreover, much of the media coverage is often misinformed or misleading and the general public is still confused about the technology and its larger implications. Join filmmaker Torsten Hoffmann (Bitcoin: The End of Money As We Know It) on his journey to better understand this decentralised technology and the promise of web3.0. This Screen Australia supported and crowdfunded feature documentary introduces the 'big brains and big egos' of this new industry including Andreas Antonopoulos, Laura Shin, Dr. Jemma Green, Charlie Lee, Vitalik Buterin, Preethi Kasireddy, Dr. Robert Kahn, Wences Casares, Samson Mow, Roger Ver, Craig Wright, and many more. Some of the hackers, hipsters and hustlers that Torsten interviewed 5 years ago are now creating a new decentralised web, while others have broken their promises. Can we trust them to build a trustless new cyber utopia or are their projects as unfairly distributed, and easily manipulated as our current systems? Reviews: "A very well balanced and easy to follow documentary that not only hears from the proponents of the space, but also its critics and controversial figures. The documentary opens the kimono to reveal many things newbies and even veterans in the space may have not known. A recommended watch for those curious about Bitcoin and its hardcore fan base." - Written by millioncents on IMDb.com "I watched the first film in 2014 as a Bitcoin noob.
