Blockchain – The Game Changer @PlovDev 2018

I had the opportunity to visit the city of Plovdiv last year for my talk at TEDxPlovdiv, and I have to say, I loved it. If you ever get a chance to visit it, I would suggest you go to their big statue atop a hill overlooking the whole city.

And I am very excited that this year, I will be visiting the city again. But this time, it would be for my talk at PlovDev – the biggest annual developer conference in Plovdiv.

This year, the event will be hosted on 24 November at Eccoplexx Cinema. There will be more than 200 attendees, many of which are students from local universities.

The talks we see in the agenda this year mainly touch the web development space – REST APIs, Microservices, SignalR. But there will be some diversity as well, as my topic is called Blockchain – The Game Changer.

In it, we will touch some of the most basic and common use cases of Blockchain, and we will go through a technical introduction to the technology by a developer for developers.

I am very excited about this event and can’t wait for it to come. If you feel the same way, want to meet some awesome people from Plovdiv, want to hear some pretty cool talks, then I will see you at Eccoplexx Cinema, 24 November.

Introduction to Solidity Assembly @ Blockchain Developers Meetup

This week, I was invited to lead the Fourth Blockchain Developers Meetup in Sofia, Bulgaria.

The Blockchain Developers Meetup is a series of events organized by some awesome crypto enthusiasts at Hack.bg. So far, I’ve watched their other meetups about zero-knowledge proofs, dark DAOs, building AI-run economies and there are many more exciting events to come.

The topic I chose for my part was something you can hardly find in any book, tutorial or documentation – how to write solidity assembly in order to achieve high-performance smart contracts.

It was surprising to see over 20 people interested in such a deep technical topic, who even endured through the end.

Perhaps I could write an article, where I extract the content of that seminar due to the scarcity of such content around the internet.

Until then, though, you can check out my slide deck and you can also explore the code snippets I demoed during the meetup, which are included in the slide deck description.

Learn Blockchain By Building it @ Java2Days, 2018

Java2Days is the biggest annual Java conference in Bulgaria. There, you can meet some of the greatest professionals from the Java world in Bulgaria and not only. Apart from that, you will be able to hear some of the hottest topics from the Java world nowadays – Java Architecture, Backend, Android, JVM languages and much much more.

But the greatest surprise is that for the first time ever this year, you will be able to hear a Blockchain topic as well. And I’m very happy to tell you that I will be leading it. For the second time, I am honored to be among the Java2Days speakers line-up.

On Java2Days, this year, we will be learning Blockchain. This new technology with the potential to revolutionize the way we interact and live. But you will not merely listen to some dry theories about it.

We will be learning it, by building it from scratch. We will address concepts like nodes, mining, synchronization, proof of work, addresses and much much more.

So if you don’t want to fall behind and learn about the potential Blockchain can bring to your business and industry, come to Java2Days on 27-29 November.

I will be waiting for you there!

Leading the Blockchain Dev Camp at Iloilo, Philippines

Today, I am writing this article from my desk at Sofia, Bulgaria. But several days ago, I was saying goodbye to my new Filipino friends at Iloilo, Philippines.

I, along with my team at Kingsland University and Software University, just finished leading a one month immersive Blockchain Development camp there.

The experience was great. For both trainers and students.

Speaking at SoftUnit Conference about Blockchain

SoftUnit Conference, Bulgaria is one of the largest tech conferences in Bulgaria. The event will be hosted on the 28 and 29 September at Paradise Center, Sofia. This year, I was invited to the conference as a Blockchain speaker.

The event is huge. There are more than 2000 attendees expected to come to this event. Also, the speakers front-line looks pretty well. Not because I am there, but because there are names which are some of the most well-known in the tech industry in Bulgaria.

And what am I speaking about? My talk is called “From Mining to Proof of Stake”. This talk will be about the problems Mining imposes on the Blockchain industry and the world we live in. Unfortunately, it is the most widely spread consensus algorithm in cryptocurrencies nowadays. So what are the alternatives? Proof of Stake? What’s that? How does it work? Why is it not massively adopted yet?

If you want to find out and you want to have a great time at an awesome event, come at the 28 September to Paradise Center, Sofia and I’ll meet you there!
