Bitcoin’s emergence as a global digital currency has been as revolutionary as it has been erratic. But while fledgling investors obsess over every fluctuation in the cryptocurrency market, nation-states are more interested in the underlying blockchain technology and its ability to revolutionize how business is done on the internet and beyond. VICEs Michael Moynihan travels to Russia with Vitalik Buterin, inventor of the ethereum blockchain, to get a front-row seat to the geopolitical tug of war over Internet 3.0.
Richie Etwaru, discusses the opportunity and implications of blockchain as a paradigm to slow/chose the expanding trust gap in commerce. He unpacks blockchain to a level of simplicity to be consumed by those that are just starting to understand and explore the paradigm. He lays out a current state of commerce, suggesting that every company is currently at risk of being disrupted or incurring severe strain from a blockchain version of itself.
Professionally, Richie Etwaru is a c-level at a Fortune 500 Company, an author, the owner of international patents, the founder of multiple ventures, an experienced keynote speaker, an angel investor, a member of advisory boards, and a recognized thought leader in the area of digital, technology, and design.
Specific to this TEDx talk, Richie is an adjunct professor of blockchain management at Syracuse University in New York, he has delivered over 100 blockchain keynotes across the world, he has written well read blockchain blogs, he has been interviewed on blockchain in online TV shows, and has advised governments and venture funds on blockchain opportunities.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx

Typo correction: At 14 minutes 45 seconds, the last index on the bias vector is n, when its supposed to in fact be a k. Thanks for the sharp eyes that caught that!
For those who want to learn more, I highly recommend the book by Michael Nielsen introducing neural networks and deep learning: goo.gl/Zmczdy
There are two neat things about this book. First, its available for free, so consider joining me in making a donation Nielsens way if you get something out of it. And second, its centered around walking through some code and data which you can download yourself, and which covers the same example that I introduce in this video. Yay for active learning! github.com/mnielsen/neural-networks-and-deep-learning
For those of you looking to go *even* deeper, check out the text «Deep Learning» by Goodfellow, Bengio, and Courville.
Also, the publication Distill is just utterly beautiful: distill.pub/

— Animations largely made using manim, a scrappy open source python library. github.com/3b1b/manim
If you want to check it out, I feel compelled to warn you that its not the most well-documented tool, and has many other quirks you might expect in a library someone wrote with only their own use in mind.
If you want to contribute translated subtitles or to help review those that have already been made by others and need approval, you can click the gear icon in the video and go to subtitles/cc, then «add subtitles/cc». I really appreciate those who do this, as it helps make the lessons accessible to more people.
