By paying only $399 per year ($33.25 per month on average), you will be able to access all 3000 courses and specializations on Coursera (entire course, not just audit) without the need to subscribe and pay individually for each program you enroll.
From another perspective, the average fees you pay for Coursera Plus are even cheaper than the individual subscription fees for any specialization (costs $39-$79).
Hence, Coursera Plus provides excellent value for money. If you are a studious student, don’t hesitate to opt for Coursera Plus now.
Below are other alternatives that you might want to consider. However, all of these courses have issues that prevent me from including them in the list.
Blockchain and FinTech: Basics, Applications, and Limitations – This edX course from the University of Hong Kong will guide you through the design rationale behind the blockchain and unveil high-potential opportunities provided by blockchain platforms.
I chose not to recommend this course because it barely touches the Fintech aspect of blockchain despite its name. Furthermore, the majority of course content consists of video recordings of guest speakers, which will not provide the best learning experience.
Blockchain Specialization – This Coursera specialization from the University of Buffalo will explain how blockchain revolutionizes decentralized application programming and steps to develop and create smart contracts and Dapps.
This specialization mainly covers the same content as Udacity’s but in a far less in-depth manner. The best thing about this course is that there are numerous hands-on exercises that help you understand the concepts in no time.
Still, I decided not to recommend this specialization because most of its content is outdated.
LinkedIn Learning – LinkedIn Learning has various short courses on Blockchain basics and relevant technologies (NFT, Dapps, etc.) However, most of the courses are outdated, which may not be optimal for taking.
PluralSight – PluralSight offers multiple short blockchain-related courses. However, most of its courses are outdated (they received last updates back in 2018-2019).
Below are lists of the “best courses” that some learners who want to continue their learning in blockchain development might find helpful.
