blockchain

In April 2019 I decided to completely stop developing my cryptocurrency project ending entire year of full time work in failed tech startup which I wanted to create. During that time:

I spent about 2200 hours hardcore coding, writing, meeting, pitching, calling and everything else related to building a startup - in that case a software product I've implemented ~ 80 000 lines of code which never experienced production usage. Registered company which did not gained any profit only expanses. Finally spent about 10 000 USD on life living costs without any income;

I would like to share my story. I believe it may be an inspiration and bring some answers for anyone who dreams about running own startup. During that time I've done tons of mistakes but I've also achieved a lot of milestones. This was a very interesting adventure and I believe anyone can enjoy that chronicle.

I invite you for the story of a dream and a failure.

The recent news about 1400 bitcoins loss caused a lot of buzz: the amount of Bitcoins worth about 16.3 million $, not any kind of exchange hack, all happened using Electrum wallet - one of the oldest and still very popular Bitcoin wallet.
I share the lessons which could be learned from that story.

Lisk to jeden z projektów blockchain, których głównym celem jest umożliwienie tworzenia efektywnych aplikacji opartych o blockchain. Aktualnie termin "Lisk" może być użyty do opisu blockchaina Lisk Core (z natywną kryptowalutą LSK), jak i do opisu SDK dedykowanego tworzeniu aplikacji blockchain. Projekt rozwijany jest już od kilku lat, ale wersja Alpha SDK (narzędzi dla developerów) jest całkiem świeża.
Przejdźmy pokrótce przez historię projektu Lisk oraz sprawdźmy w jakim miejscu projekt znajduje się obecnie.

Lisk is one of the blockchain projects, whose primary focus is to enable building highly efficient blockchain based applications (dapps). The term "Lisk" at the moment can be called to describe the Lisk Core blockchain (with the native LSK cryptocurrency) and the SDK for building blockchain applications. The project is developed already few years, but the Alpha SDK version of Lisk is quite fresh.
Let's make short overview of the project genesis (history) and the current state.

The blockchain technology spreads. Mainly this can be visible in the context of cryptocurrencies popularity gain (which can be noticed by rising Bitcoin price). Blockchain became useful or even created plenty of new branches like tokenization which who knows - maybe will revolutionize the investments and the way we represent the ownership in general.

Choosing the right technology can impact development process and among the others: the performance of the solution. I would like to compare the performance of the Hyperledger Fabric chaincode implemented in the Node.js and Java.

Entering the Blockchain world you can be sure, that sooner or later you will hear about the Hyperledger. Even if the blockchain technology is most often related to Bitcoin or Ethereum as the grandfathers of that technology, Hyperledger is very important player which grows stronger very fast.
