Took the class on Cousera and it was very informative. I often reference the book as well. To be honest, it wasn't the technical aspects of the class but the "political economy" implications of crypto-anarchy that were particularly fascinating. At the time, the Isle of Man regulations had just come out as the first attempt to integrate bitcoin into the market. Prof. Felten's mild pushback against the consequences of a shadow, unregulated monetary system really moderated my own opinions. I would love to see a deeper historical framing of digital money as a way to think about the future.

The recent Filecoin ICO has also gotten attention. And this might be a good place to jump off for a second course: "Applied Crypto Entrepreneurship". How to package, market and sell your existing computing resources, knowledge and skills for financial gain and social good. How blockchains and DLTs can be used not just to encode trust, but transactions for all digital goods and data. Even a section on using machine learning for time series analysis and building algorithmic trading bots. And also including lots of practical exercises in smart contract development and introductions to third-party tools, APIs and BaaS platforms.

Good luck and looking forward to seeing the next version! I'd say you've really got your work cut out for you trying to stay up-to-date on this ever shifting foundation.

I'm utterly sick of the politics around the scaling debate, but it would be comforting to read an impartial design document analyzing the many legitimate technical approaches to adjusting the number of end-user Bitcoin transactions that can happen in a given unit of time. The technical question is not as zero-sum as the warring political factions want us to believe.

Such a discussion would be generally applicable to an abstract cryptocurrency, and thus pertinent to this lecture series.

Thank you so much for doing this and posting it online. I have learned a tremendous amount from your coursera course.

Whilst I appreciate that you are not seeking to teach the details of specific currencies, could you use some of the newer currencies to teach by example?

For example, could you discuss some of the concepts detailed in several of the white papers (and the legitimacy thereof) such as IOTA's tangle or some of the features of the new coins built on ethereum or the utilisation of XRP by banks?

Could you discuss future possibilities such as decentralized exchanges?

Thank you again.

Could you cover the topic of SegWit? Since Bitcoin core has adopted that as their first scaling code change post 1MB blocks, I think it would be helpful to understand what's going on with that.

I loved the book. Read it front to back. In an update I would love to see a deeper dive into smart contracts, the Oracle problem, thoughts on ICOs.

Can't wait to watch the videos.

Seems that some new coins such as Ethereum have relatively different designs than those of the old coins. It would be great if you could explain those a bit more.

A lecture series walking through the internals of Bitcoin Core source code would be well received.

I imagine it must be fairly surreal to be Satoshi, period.

I thought "he" was the CIA? :D

What if Satoshi isn't a single person but an entire organization?

Specifically what if Satoshi is a decentralized autonomous organization and the original bitcoin paper was an output generated by the Satoshi DAO?

Why would Satoshi do that you may ask. Well they need to make sure the whole blockchain concept was created in the first place or otherwise Satoshi DAO would not have come into existence...

what do they code?

What did you expect? This course are theoretical course. You are looking for wrong thing in wrong place!
