Julien Klepatch

Hi and welcome to Eat The Blocks!

My name is Julien Klepatch. I am a blockchain developer, and I run this website,

In 2011, one of my friend showed me this new thing called Bitcoin. I briefly had a look at it, but I thought it would probably only be a fad, so I dismissed it. In 2016, while randomly sifting through Hacker News links, I saw this headline about the DAO hack. Curious, I read the article, and that was the beginning of my journey inside the amazing world of crypto currencies.

Quickly after reading about the DAO hack, I decided it was time for me to understand what was Bitcoin and the blockchain. I bought myself a copy of the wonderful book Mastering Bitcoin by Andreas Antanapoulos. I read the whole book in a day, fascinated by the technology and the political changes it could bring to the world. I was so into it that I re-read the book 3 times the following weeks.

But what about this news that brought me into the blockchain industry, the DAO hack? It wasn’t about Bitcoin, but about Ethereum. I realized that this new crypto-currency generalized the ideas of Bitcoin by allowing to run so-called smart contracts on the blockchain. ¬†One could not only have transactions on the blockchain, but also run small programs. Sky was the limit. The concept was so powerful. I got hooked instantly.

Fast-forward one year, I have now accumulated a solid experience in blockchain technology, having helped many ICOs and blockchain projects, mainly on Ethereum and Monero. I contribute to blockchain open source projects, such as the Monero RPC Client.

It wasn’t easy though. Although the blockchain technology is great, the learning resources are still limited. In particular, I wish there was a good screencast to teach blockchain developers.

That’s why have decided to create this screencast, I will release regularly short videos about blockchain technology. It will be mainly about Ethereum Dapps and smart contracts, but we will also study other blockchain technologies such as Bitcoin and Monero. The videos will be posted on the youtube channel of Eat The Blocks.

Happy learning, and feel free to reach me at julien [at] eattheblocks [dot] com, or on twitter at @jklepatch.

    I really enjoyed your story. I am starting out as a Blockchain developer and have signed up for your Dapp30 course. How did you get involved in open source contribution?

      Just saw your message, thank you!
      I looked for easy commits, with "easy-for-beginners" or "help-wanted" on github.
