Anyone found good free BLOCKCHAIN study resources besides the obvious ones?
I've already gone through the standard "BLOCKCHAIN" results on Google and most of it is just selling prep courses. Looking for actual free resources.
What I've tried:
- Practice tests here (solid, especially for Blockchain Developer)
- A few YouTube channels but the quality is all over the place
- Reddit threads from 2+ years ago (some outdated)
What I haven't tried yet:
- The official BLOCKCHAIN study guide — is it actually worth reading cover to cover?
- Library resources — anyone actually found useful materials there?
- Specific YouTube channels that cover BLOCKCHAIN exam well
I don't mind paying for something that's genuinely better than free, but I want to max out free options first. Budget is tight.
What resources did you use that you'd actually recommend?
If you're looking for a starting point, the blockchain developer test 2 is worth trying — the questions closely match what you'll see on test day.
I actually failed the first time by a few points. Total gut punch. But passed on the second attempt with a comfortable margin.
What changed: I stopped trying to memorize answers and started actually understanding the material. Specifically on BLOCKCHAIN exam — I went back to basics and worked forward from first principles.
Also switched from reading to doing. Less time with the textbook, more time on practice questions with detailed answer explanations.
You've got this. The second attempt is always better because you know exactly what the exam is like.
Quick data point: I spent 8 weeks studying, 2-2 hours a day, and passed with a 78%.
The section on BLOCKCHAIN exam took me the longest to feel confident about. Eventually I just drilled practice questions until I could answer them without hesitation.
What testing center did you end up booking? Some of them have much shorter wait times than others right now.
Quick update: just cleared 84% on my most recent blockchain-developer practice set using blockchain developer smart contract development. Sitting for the real thing in 3 weeks. Feeling cautiously optimistic.
For anyone finding this later: blockchain-developer is passable with consistent effort even working full time. I studied 67 minutes a day for 11 weeks. The blockchain developer smart contract development kept me honest about my actual gaps.
Quick update since I posted a few weeks ago stressing about this -- finally broke 80% on a practice test yesterday, which honestly I didn't think would happen this fast. The blockchain fundamentals stuff clicked once I stopped trying to memorize everything and just kept running through the practice questions until the patterns made sense.
I'm aiming to sit the real exam in about three weeks. Nervous but I feel like I'm actually ready this time, not just hoping for the best. If you're in the middle of studying right now just keep drilling the practice tests, it's slow at first but it really does compound.
