Bitcoin Q&A: Schnorr Signatures and the Privacy Roadmap Video

How important are privacy improvements to Bitcoin in the roadmap? How will second layers and atomic swaps help with this? When will Schnorr signatures / signature aggregation be added to Bitcoin? What are Taproot and Graftroot? Will it be done through a soft or hard fork? Should we keep transaction transparency instead of adding privacy features?

CORRECTION / CLARIFICATION: At 3:47, I mention that Schnorr signatures had to overcome "patent encumbrances" and guessed that the patent expired somewhere around 2010. The precise expiration date of the U.S. Patent (No. 4,995,082) was February 2008. At 4:22, I say that ECDSA and EC-Schnorr are based on the difficulty of solving the discrete logarithm problem over a prime-order field. While this is true for the digital signature algorithm (DSA), ECDSA and Schnorr are based on the discrete log problem over an elliptic curve group. (h/t Daira Hopwood)

Chapters
0:00 I know we have Zcash and Monero. Do you see a second layer protocol for Bitcoin that will render those unnecessary? Which one of those protocols is the most promising for obfuscation and keeping your transactions private?
2:43 After a quick reminder of what doors Schnorr signatures will open for Bitcoin, could there be any reason not to want them implemented into Bitcoin? Can you also tell us how you think this would be rolled out, in a soft fork or a hard fork? Is there any timeline for these changes?
11:53 If people will have an untraceable, anonymous cryptocurrency with a high degree of privacy, don't we also need a traceable and transparent cryptocurrency for states, NGOs, and politicians? Could you do atomic swaps between them?


These questions were part of the monthly live Patreon Q&A session in July and the Denver event as part of 'The Internet of Money Tour' at the Hilton Denver Inverness, which took place on July 28th and August 6th 2018 respectively.

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. 📈
