Comentários e feedback de alunos de Bitcoin e Tecnologias de Criptomoedas da instituição Universidade de Princeton

Amazing course

The course covers not just mechanics of bitcoin and some altcoins per se, but also explains philosophy behind block chain, reasons why particular design decisions were made, alternatives considered and how the system protects itself from possible attacks. The material is also interesting as an application of different crypto primitives (but their nature is not covered). Assignments are cool, but... java-based. One of them helps to understand alternative approach to reach distributed consensus which is not covered in the lectures (see ripple).

Extremely good and self contained course. Highly recommended

If possible I would rate a 4.5 out of 5 for this course. The lecturers are very good and comprehensive (compared to all other sources I found in the web) at explaining how cryptocurrencies (especially BTC) work and what the up- and downsides are. The workload for lecture videos is pretty low for each week (1-2h a week) which makes the learning targets pretty easy to achieve in the proposed time. I found the programming assignments quite difficult when beginning with each one, since one needs to read and understand (most) of several hundred lines of starter code and also needs to understand the task setting which uses a somewhat different terminology than used in the lectures. Also for assignment 1 and 3 there is no simple test code provided to at least partially test your code submission candidates. That makes it hard to debug in case of small logical errors that cannot be detected by the compiler but probably break the complete solution and result in a very low score. I had no experience in Java programming before the start of this course but with a one day crash course of Java for Python programmers I managed to complete all assignments in time (and learn at least the basic principles of Java, which is nice for itself). Each assignment is expected to take 3h by the creators of the course. The come up with a high score (not just passing) I needed to invest about 5-9 hours for each assignment which is probably but not exclusively due to the little knowledge of Java. Nevertheless I would encourage the creators of this course to use Python assignments for future courses since this would make prototyping a lot easier (due to it's interactivity) and attract more students without having real downsides (at least to my knowledge). All in all I really enjoyed this course and would like to thank all lecturers and the Princeton University for making this course accessibly free of charge for everybody. Thanks a lot!

Exceptionally detailed introduction to Bitcoin. The exercises were thought provoking and helped understand the bitcoin mechanics and the problems the Bitcoin creators needed to solve. The exercises are however tough without easy access to a testing harness.

A LOT of information. It put a lot of the technology into perspective. Definitely worth the time if you're trying to pick up some knowledge.

If I had one criticism, it is that some of the stuff included is already dated. Which is bound to happen with tech that moves so fast.

very interesting and useful.

Best course I've had for Bitcoin!

One of the best courses I have had! Great for understanding the technical aspects, as well as the economics and social implications of blockchain technologies. Thanks a lot!

Very good course,

Excellent, Thanks you

A fundamental course in crytocurrency. Very interesting.

Absolutely essential for everyone who wants to know everything about Bitcoin and blockchain. Big shout out to the instructors and dept of the course. Would absolutely recommend!

Dev work is too difficult for noobs, you'll probably need to make others simpliest exercises.

Programming assignments are probably the best part as they force your to learn.

Great course to learn about bitcoin and blockchain technologies.

This course is somehow old 2014, but completely shows the how the bitcoin works, and in fact how crypto currencies work in general. They have an awesome chapter about anonymity. Extra material weeks are really good.

Great content

awesome!

overall excellent

Very well organized course about this fascinating technology!

Incredible oportunity

It is good course with clear technical concepts

This is a very good overview course for Bitcoin and underlying blockchain and crypto technology - along with homework that is difficult enough to force one to think a bit and review your java skills. Appreciated and enjoyed.

Good all round content and programming assignments ensured we had to understand details
