Created by: Blockchain at Berkeley Organization

Last updated November 2017

Our take

Based on the ratings of 736 students, a sample of their written reviews and the syllabus, as the course stood in November 2017. No course pays to be reviewed.

Despite the long syllabus on its page, this is only the free first module of Blockchain at Berkeley's Ethereum bootcamp. It has eight lectures and 42 minutes. It sets up Truffle, deploys a Greeter contract and attaches a React front end through web3. The Solidity in-depth, MetaMask deployment and security modules listed in the description are not in it. That gap is the main thing to know going in. About 25,600 students have taken it, and the rating is 4.3 from 736 reviews.

Reviewers like that it is short and to the point. One calls it a step-by-step guide for beginners, and another says it got their first Hello World running on Ethereum. Blockchain at Berkeley's instructors are called technically good, though a couple of people found the delivery flat and the audio weak. The complaints are louder in the low stars. 105 of the 736 ratings are one or two stars, and many of the low-star reviews in our sample say the code is outdated. Truffle migrate errors and project files that no longer load by default are among the specifics. Some also wanted more explanation of what is being typed and why.

The last update was November 2017, so expect to fix commands as you go, or look up a newer walkthrough alongside it. Since it costs nothing, an hour is a small risk if you are curious and comfortable debugging npm and Truffle errors. Anyone who wants to learn Solidity properly should start with a course that is current. One reviewer said it ends with a screen asking for a full course and was not inclined to take it.

Best forCurious beginners who want a quick look at Truffle, web3 and a React front end before choosing a fuller Solidity course.
Skip it ifYou want current Solidity or the security topics in the syllabus; those modules are not in this free lesson.

Pros

  • Short at 42 minutes, so a first Hello World on Ethereum fits in one sitting
  • Covers Truffle init, migrations and a React front end talking to a contract through web3
  • Free, with about 25,600 students and a 4.3 average from 736 reviews
  • Reviewers call it a clear step-by-step start for people who already know basic JavaScript

Cons

  • Last updated in 2017, so newer Truffle and Node versions break the commands shown
  • Only the free first module; the Solidity depth and security topics in the syllabus are missing
  • Flat delivery and weak audio, with some steps typed without much explanation
short but meangful contents and helped to run my first Hello World program on Ethereum

Labeled beginner and asks for basic JavaScript; commands are shown on Linux, and one reviewer wanted a Windows walkthrough instead.

This course was actually great, I now have a study guide for my front end blockchain project.

short but meangful contents and helped to run my first Hello World program on Ethereum

By Mandla William Mahlangu on 8/18/2019

I have the knowledge only on when i should buy or sell currencies, buy and hold as doing investments. What i am not clear of is that transactions making, like funding accounts online. This is the knowledge i need to on thanks.

By Alfred Farrington on 1/29/2019

Yes it was, but here is what is going to happen to new users. Some of the steps didn't work because there was an update. I know it's hard to keep updating the training, but that is what will make it valuable (where you can charge, and patrons won't complain).

By Jeremy Josey on 12/14/2018

Would like to see it go a little farther maybe a full crud example. Good job!

By Dwight Spitzer on 11/3/2018

Course needs to explain some things in more detail to help in debugging. Maybe tools/library's have changed too fast or I did something incorrectly or out of sequence, but nearly impossible for 'beginning' level to debug mistakes.

By Jaydipsinh Raol on 8/19/2018

excellent !! To compile and migrate greeter contract , migration file for greeter should rename like 2_deploy_contract.js in order to migrate successfully. otherwise it wont be deploy on server.

By Xinghou Liu on 2/25/2018

Need to update with the truffle 4.0.x way of testing, no need to install TestRPC anymore.

By Nikola Stamenkovic on 12/24/2017

Very good course to start with. Videos are very clear and up to the point. I enjoyed it. I gave it only 4 starts, because virtually there is no help in Q&A section and there are many unanswered questions. That is definitely a part which is in need of improvement.

By Darron Beetge on 12/13/2017

I'm really enjoying the course so far. I had a few issues setting up my development environment at first, but realised it was my mistake after watching the videos again.
