Develop your own cryptocurrency with Substrate Part 2
This is the second part of a series where we are implementing an ERC20 token with a Substrate node and accessing it from a NestJS application. The first part is available here. In this part, we will have a glimpse of the implementation of the ERC20 token using Substrate Runtime. We will also access it from a NestJS app. You can access the working project on GitHub Before we start Before we start, build the node, purge the chain, and run it in development mode. We will be using the smart contract…
What do test automation and karaoke have in common?
A well-known strategy for explaining the unexplainable and adding context and meaning to something complex and obscured is using a metaphor. Engineers usually find automation testing hard to describe in detail, especially to a less-technical person. It is a process rather than an action or idea and there are so many different properties of it and variables in it that it can be tough to wrap one’s head around it. That is why I came up with a quirky comparison that hopefully will make things…
No risk, no fun or: How I learned to stop worrying and love the risk management.
I’ve been researching and writing about the agile approach to risk management for quite a few years now but mostly in relation to safety-critical software (for example here , here and here ). This time I wanted to address other types of projects, how it can work in practice and why the risk is not necessarily a bad thing. I started to write this blog post back in March, I already had the title and some notes. And then something unexpected (but apparently still predictable) happened - a global…
Develop your own cryptocurrency with Substrate PART 1
In this blog post I will guide you through the process of implementing an ERC20 token with use of a smart contract on a Substrate node and accessing it from a NestJS application. If you would like to get a basic concept of what blockchain, Substrate or smart contracts are you may check our previous blog post. NestJS is a framework for building Node.js applications, to get the basics you can visit it's documentation website. You can access the working project on GitHub. Substrate node First of…

Which hat should I wear today? How to make your team meetings more effective
There are lots of efficient brainstorming techniques for teams such as visualisation-based method, step-ladder technique, mind mapping, rapid ideation and many others. All of them can create a large space from which to pull the best ideas and make your meetings successful, but today I would like to focus on one method that I have found really meaningful and effective - The Six Thinking Hats method by de Bono. I heard about Edward de Bono a few years ago, but it wasn’t sooner than last year that…
Why would you use Substrate?
Substrate is a framework to build blockchains. People behind Substrate had built many blockchains before and noticed that they had to do the same hard work over and over again. Thus they tried to create a framework which would make deploying a blockchain as easy as can be. At the same time they wanted it to be as generic as possible, so that a developer can customize it to their needs. Before we dive into Substrate, let’s take a look at what the blockchain itself is. Data Blockchain is a…
Brief introduction to transfer learning
In this item, I want to share with you the core idea behind transfer learning. We will solve a simple classification problem where we will try to correctly classify surfing, windsurfing and kitesurfing images but you can easily solve different problems relying on described steps Transfer learning is a very important and broad research problem. In general, it relies on transferring domain knowledge from one solved task to another unsolved one (but somehow related to the solved task). Consider…
7 sins of demotivation every manager should be aware of
Being a team manager is quite a challenge nowadays as your team is usually a bunch of people with different personality traits, different life experience, different needs, priorities and often a different attitude to life. And what is more important, being a manager means being cautious enough to make these people work effectively together, and being careful enough not to omit the moment of potential crisis that would not be able to be undone anymore. I sometimes meet managers who do not see…
Creativity in quarantine?
Today during the pandemic times, the times of social distancing, proper 30 sec washing hands, times of sanitisers, masks, gloves and quarantine we all seem to feel isolated and lose our creative vibes. I don’t want to divide people here on creatives and non-creatives. I believe that every profession requires creativity and every person is creative in their own unique way. Creativity is an inspiration drawn from the outer world, from people we meet, from conversations we conduct and things we see…
