Bitcoin Q&A: MimbleWimble and Dandelion Video

What is the story behind MimbleWimble? What is Grin? What is a Dandelion transaction relay, as described in BIP156, and how does it improve the anonymity of the Bitcoin network?

CLARIFICATION/ CORRECTION: At 1:14, I talk the origins of MimbleWimble. The PDF was submitted to the Bitcoin research IRC channel on August 2nd, 2016. The pseudonymous author used the name "Tom Elvis Jedusor," which is the French version of Voldemort's real name. I also say that the name "MimbleWimble" was referencing the name of a spell from Harry Potter, which is the Tongue-Tying Curse and prevents someone from speaking about (not "seeing") something: http://harrypotter.wikia.com/wiki/Tongue-Tying_Curse

At 6:08, I was unable to list the names of the team members behind the Dandelion proposal. They are Giulia Fanti, Shaileshh Bojja Venkatakrishnan, Surya Bakshi, Bradley Denby, Shruti Bhargava, Andrew Miller and Pramod Viswanath (researchers at Carnegie Mellon, MIT, and the University of Illinois).

NOTE: As usual, this video is intended as an educational resource on topics such as blockchain protocols (i.e. MimbleWimble) and not as an endorsement of specific implementations (e.g. Grin).

About the Site 🌐

This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥

Origins of the Idea 🌱

The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠

Challenges Faced 🤔

Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.

Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍

Creating Truly Random Links 🛠️

The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.

About YouTube 📺

YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟

Content and Users 🎵

Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.

While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.

Monetization and Impact 🤑

YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.

As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. 📈
