Over the past several years there has been a lot of talk about cryptocurrencies, such as bitcoin, and the blockchain technology that underpins them. However it can be difficult to understand how the blockchain actually works in practice, and why it is such a clever method for currency exchange. Two of our graduates are currently developing our own cryptocurrency for use within Scott Logic, as an attempt to better understand the practical uses of the blockchain. In this blog post, we aim to explain the inner workings of the blockchain and help people to understand how it manages to keep transactions both secure and anonymous. This post will go into the low level algorithms of blockchain and provide verified examples alongside each algorithm; this post is not for the faint of heart!

This post uses React to show how we can use features from functional programming in everyday JavaScript, and integrates RxJS to show how these approaches are common across many frameworks today.

Mondo Bank has recently moved into public Beta, sending out 1,000 cards to trial customers each week. I received my Beta card a few days ago, and have been using it ever since. This blog post takes a quick look at the Mondo API and how I used it to automate expense claims!

Automation of user interactions in browsers can be difficult. Even more so when you have to hunt for elements in a single page application. How can we ensure reliable location of these and reduce flaky checking?

Business must attract broader people into software and ensure the gender-based conditioning that has resulted in a male industry is confined to history.

d3-path is an abstraction over SVG path creation which uses the canvas element's Context2D interface. Previously creating path generation code involved a lot of concatenating SVG path commands like M0,0 or L2,2, and the somewhat more cryptic C70 20,120 20,120 10. Even with ES6 string interpolation such code can be incredibly hard to read (and write!).

I recently created a site which I'm proud to say now hosts an impressive collection of tweet-sized D3 creations from the hugely creative people of the internet. In this post I'll talk through deconstructing one or two of those creations with the aim of giving any aspiring artists a starting point.

Making the jump to fully modularized applications in javascript is now incredibly easy with ES6 modules and javascript package manager (jspm). We'll take a look at the refreshing simplicity in the jspm workflow and how it goes about achieiving this.

The next version of D3, the data visualisation library, is on the way. As we maintain D3FC (a charting library built on top of D3) we want to stay on top of those changes, to make sure that the library makes appropriate use of any new functionality and to embrace any new conventions that have emerged.
