You might be somewhat familiar with the idea of blockchains, or you might have only heard of the phrase in passing (or you might not have any idea what a blockchain is but thought the article title sounded more interesting than the topic currently being discussed in the meeting your supervisor is making you sit through…). Either way, there are still a lot of questions that you probably have. What is a blockchain? How does a blockchain actually work? Are blockchains really as secure as they claim to be? Can you invest in blockchain itself? What is the advantage of blockchain? Maybe you’re getting more involved and want to delve deeper into the exciting and fascinating world of blockchains. In that case, your questions might be more advanced like: What programming language is used for blockchains? Is blockchain open source? Is blockchain hackable? Are there other use cases for blockchain beyond bitcoin storage? Will blockchain change the world? No matter what your string of queries, the best place to find the answers is always the internet. There are thousands and thousands of videos out there explaining the definition, uses, and inner workings of the blockchain. I know what you’re thinking. Great! Let’s sift through thousands of videos to find the ones that actually make sense, answer your questions, and give over the information you want in an appealing manner. If that doesn’t sound as much fun as a barrel of monkeys (why would a barrel of monkeys be fun anyway?!), then you’re in luck. Since we know how interested our readers are in the topic, we’ve aggregated the best videos from across the web that talk about blockchains. From the straight-up definition to the more advanced jargon that most of us will never really understand, check out the 5 most useful blockchain videos out there to help you get started down the path of blockchain wisdom. Great Blockchain Video #1: What is blockchain? CNBC Explains by Tom ChittyAnd here’s why: It gives you all the important information you want to know, starts from the beginning, and explains the entire concept well There are a lot of blockchain for beginners videos. You’ll recognize them by the names like, what is a blockchain, blockchain explained, or blockchain for beginners. The truth is, though, that most of these videos take a lot for granted, assume you know more than you actually do about the topic, or don’t really explain the concept in a practical way. And that’s why this CNBC exclusive done by Tom Chitty is our first recommendation for anyone who is just starting out on the learning journey to blockchain technology. If you can understand the accent and overlook the poor wardrobe choices, then you can actually learn a ton from this explanation video. Chitty goes through the ABCs of blockchains, showing the negatives alongside the positive uses for blockchains. He also shows you exactly how it works, why it is so secure, and what future applications might be possible for this technology. The CNBC video also takes you through the benefits and possible financial ramifications that are involved in embracing this technology. All in all, Chitty does a great job of explaining a complex topic and gives you a lot of food for thought. Great Blockchain Video #2: New Kids on the Blockchain by Lorne LantzAnd here’s why: Practical ways people are currently putting blockchain to good use and how they will even more so in the future Aside from the fact that this is a TED talk, which automatically makes it amazing, Lorne Lantz explains exactly how blockchain works quickly and eloquently. He then moves on to break down how blockchain works within the bitcoin universe, something that most people are curious about. Finally, Lantz illustrates how blockchain can be used in other instances. This is not only fascinating, but it is a great way to educate the public about how this brilliant technology can be utilized in the future and within our day-to-day interactions. Great Blockchain Video #3: Understand the blockchain in two minutes by Institute for the Future (IFTF)And here’s why: It’s fast and easy to watch but surprisingly thorough for a two-minute video We all want to know more about various topics like cybersecurity, the effect of drug and alcohol combinations, or depression and prevention. But let’s face it, we’re lazy! And what’s more, our attention spans are shorter than Michael Jordan’s laughable attempt at becoming a baseball star. For this reason, I am highlighting this video from IFTF. The Institute for the Future does snapshots of interesting topics, trending concepts, and technological advancements that they deem worthy of a closer look. This video on blockchain is just two minutes long, but somehow it manages to explain everything you really need for a cursory understanding of the topic (and even a little more). So, if you’re already antsy just from reading this intro, check out the IFTF blockchain video (you can watch it double speed if you’re that strapped for time!). Great Blockchain Video #4: How the blockchain will radically transform the economy by Bettina WarburgAnd here’s why: Food for thought on a more advanced technology that is offering a safer and more reliable forum for value exchange Whether you’re a conspiracy theorist, a budding financial mogul, or just someone who thinks it’s really cool to see entire empires brought to their knees by the unlikely underdog (think David and Goliath or Spartans against the Persians), this is a must watch video. Bettina Warburg explains briefly how throughout history we have used various methods to exchange values within our societies. From protection to fish and coins and now to the more advanced banks and digital currencies, the world has always had its way of trading valuables for desired goods. In this video (yep, another TED talk), Warburg takes us through the process of how blockchain is the next chain in the evolution of value exchange. She expertly breaks it down, so you can see how this makes sense on a sociological, economic, and technological level. What’s more, she demonstrates how blockchain is the safest, easiest, and most reliable method we have come up with yet. So basically, Warburg’s video shows viewers how blockchain is like a solid, unbreakable safe, which makes it more trustworthy and evergreen than any other transaction method that came before it. I don’t want to spoil the video for you, so just watch it for yourself. Great Blockchain Video #5: Blockchain: Massively Simplified Richie EtwaruAnd here’s why: A fabulous twist This video starts off seemingly like all other beginner’s guides to blockchain. It talks about the early days of the internet (those dark times of dial-up modems and even earlier ARPAnet packet switching technologies) and quickly fast forwards to show you how kickass technology has become (as if we needed a video to tell us that). All very interesting stuff, but nothing new. And then Etwaru does something that nobody else we’ve seen so far attempt. He takes blockchain and explains how it can bridge a gap that no other technology has been able to traverse, a gap that is so fundamental to human interactions and our society as a whole that it’s truly a marvel that we’ve gotten this far in history without having a more reliable failsafe for it. In this video, Etwaru explains that inventions are all about bridging gaps in our society, world, and lives. He then continues on illustrating how blockchain bridges the gap of trust, one of the most core and necessary element of our society, one that holds trillions of dollars on its wobbly shoulders. With his mesmerizing voice, witty personality, and mind-blowing revelation, Etwaru really blows the top off of this simplified concept. And that’s what makes his video on blockchain really stand out. Blockchain Explained, Expanded, and Explored So, there you have it. Sure, you could sit there for hours and hours watching video after video, sifting through the crap and suffering through the clunky terminology, but why bother? We’ve rounded up the cream of the crop, the best videos out there, the ones that’ll give you the biggest bang for your buck. In fact, if you just watch these five videos, you’ll: • Know all the basic information about what blockchain is, how it works, and what it’s used for • Be able to hold your own in a conversation that is arguing the different sides of blockchain • Have some interesting ideas to help stir up controversy when everyone’s talking about this technology at the office water cooler, at your next family barbecue, or this Thursday night at the bar • Just generally sound like a smartass because you know more about an interesting topic than almost anyone else in the room Of course, if you are a real newbie to the blockchain concept, then here’s some quick information to warm you up to the subject and to ensure you don’t sound like a complete idiot the next time the subject comes up. • Blockchain is an online database that can be accessed by anyone and from anywhere in the world (provided you have an internet connection) • Blockchain is decentralized, which means its ledger is shared on every computer around the world, so it has no single central location • Blockchain can be added to by anyone, but once a record (or block of information) is created, it cannot be tampered with, changed, or deleted • Bitcoin is NOT the only use case for blockchain technology. In fact, it’s just the beginning baby! From banking to cybersecurity, crowdfunding, Internet of Things, and healthcare, blockchain has so many real-life applications. Now that you’ve got all this information in your head, knowledge is power. So, get out there and do the best thing anyone can do with a boatload of interesting information; flaunt it in front of your friends. This article was originally published at YouTubetoMP3Shark.
