Blockchain distributed laboratory

Why am I watching Blockchain Online Course from Distributed laboratory? 

Some time ago I started using cryptocurrencies in my calculations. Naturally, my first cryptocurrency was bitcoin. Many people know that using bitcoin for payments is quite problematic. But I was not the one who "ordered the music" and I had to get into this process that is new to me and involves a lot of unfamiliar to me operations.

FROMtime I learned how to turn deposits of coins into fun process of buying and-Selling of altcoins, but after some disappointing losses I decided to give up trading and went deep into mining. 

Soon I got interested in investing in projects at the stage of ICO. That was how I for the first time encountered new terms: blockchain, smart-contracts, decentralized assets management, tokenization of real assets. There was more and more information. I faced with a lack of knowledge and with a search for answers to questions I had.

I am not new to internet trading, I work in a successful internet project and I am interested in all possible activities related to IT and the Internet, so it was only a matter of time before I was introduced to the Distributed Lab campaign. And it was just a matter of time.


Last summer I heard that in Kharkiv there will be a Bitcoin Meetup Kharkiv. I visited this event. That was my first time to get acquainted with Distributed Lab.

In a relaxed atmosphere, the speakers made reports on topics that have long been interesting to me. They shared information and the latest trends in blockchain technology. After this event, I tried not to miss such events in Kharkiv and Kiev. In addition to reports from the podium it is very useful to communicate with each other live and to ask the speakers questions and get answers to them.

At one of the meetings I met with Pavel Kravchenko. There are such charismatic people who evoke sympathy at first sight, have an excellent command of the subject and are able to captivate the audience of listeners. MITAPs conducted by Pavel and Distributed Lab are very useful in terms of information, they popularize cryptocurrencies and solutions created with the help of blockchain technology, these mittaps gather interested audience and constantly expand the range of questions discussed. But all of us know the feeling when after an interesting and information-packed event, after a while it is very hard to remember all the nuances of speakers' presentations. Mitap is a place to get acquainted with the issue but not for its detailed study.

Pavel Kravchenko is well aware of this peculiarity of the human brain, that's why on one of the mitaps he announced an online course on Blockchain, which unites knowledge about how blockchain systems and cryptocurrencies work. Pavel Kravchenko makes no secret that this course was created by Distributed Lab for self-promotion and to find new developers for his team, nevertheless the course gives the most objective information about the technology blockchain technology and cryptocurrencies.

Online course on Blockchain is available for everyone on YouTube channel

At present the course consists of 31 video lessons which you will need time, patience and desire to learn new knowledge. Course lectures are made in an easy to understand and easy manner, at the same time lessons are filled with useful information and visual materials.

Among the lecturers of the online course are true professionals who have a lot to teach their listeners:
  • Pavel Kravchenko - the founder of Distributed Lab
  • Bogdan Skryabin- researcher of Distributed Lab
  • Yaroslav Panasenko- Distributed Lab developer
  • Roman Oleynikov- researcher at IHK
  • Andrey Sobol- CTO of Pandora Boxchain
  • Alexander Ivanov - mathematician at Pandora Boxchain

How useful is this online training course??

I've attended about 10 mitups organized by Distributed Lab company, so I know the lecturers already. The topics of lectures are also familiar, because all these questions were covered in the meetings.

But it is one thing to sit in a crowded room with a mass of irritants and try to grasp the essence of the report, and quite another thing to watch this report in a comfortable environment at a convenient time, with the ability to see the repetition of incomprehensible moments.

This training course is a wonderful addition to the meetings and it seems to me that it should be continued and filled with new lectures, and there will come a time when meetings will be a useful addition to the course.

Why am I wasting my time studying this course??

I have plans to apply Blockchain technology to my existing business. In order to communicate with developers and to draw up a correct and valid requirements specification, I must have a certain set of knowledge. I gain this knowledge thanks to this online course.

Now I will briefly describe each of the lectures. To be honest, I haven't studied all the lectures of this course in details yet, so I am going to describe them word by word.
