Master Blockchain Fundamentals — Gain the Proficiency to Kickstart Your Career Today

Even If You Know Nothing About Cryptography, Blockchain Networks, or Smart Contracts
(This Training is Tailored for Mid-to-Senior Level Java Developers)

This program is for you if:

You’ve reached the salary ceiling in your current company and are looking to transition to a better job.
You’re tired of writing your 549th CRUD and front-end form to fill it.
You want to deeply understand how blockchain works.
You’re at the beginning of your journey.
You enjoy learning through practical exercises.
You need contact with someone who can answer your questions and address your doubts.
You don’t have the time or ability to search for everything on your own.
You’re encountering projects that use blockchain at work and need to know what you’re doing.

This program is not for you if:

You’re more familiar with blockchain than your pocket.
After reviewing the program content below, you conclude you’ll be bored because you already know everything.
You implement your own blockchain solutions daily at work without any issues.
You make PRs to white papers with corrections to official ETH/BTC documentation.
You’re not willing to invest time in independent work, such as completing homework assignments.

About Your Instructor

I was fortunate enough to join a team developing a new Ethereum client (Mantis) around December 2016. (I’ve been working as a programmer since 2010). During this project, I learned from scratch how blockchain works, as well as the underlying mechanisms of smart contracts, network, and other components. I had to learn this if I wanted to be a part of the project.

It cost me some stress and a lot of time.
Using this knowledge, I’ve developed this course to save you stress and time. This is the exact training I wish I had at the beginning of my work with blockchain.
From what I’ve observed, even official materials such as white and yellow papers can contain errors that can cause frustration, for instance: my correction to the Ethereum documentation [link].

Testimonial from a Participant of the First Edition:

Was it worth the purchase? Definitely. Even if I didn't use the knowledge immediately, I now have a resource I can return to for a refresher, complete with up-to-date information. I see vast potential in this technology and I aspire to contribute to its development.

Bartek

Every trainee gets to implement individual elements that, later in the course, enable them to create their own blockchain. The training is perfectly structured, and Adam's knowledge and teaching skills make it the best source of blockchain technology information I've found in the Polish market.

Arek

Your passion inspired me to delve deeper into blockchain-related topics. I've started tinkering with my own projects, particularly involving smart contracts, and I've even managed to monetize them. The training cost has already paid for itself several times over, and we're not even halfway through!

Piotr

I participated in the first edition of Adam's training, and I highly recommend it if you have the time and desire to understand the nuances of Ethereum. The smart contracts segment will open your mind to new ideas and blockchain applications. The training is practical, and the examples make it incredibly engaging. I believe it will be money well spent.
