Many have emphasised the potential of blockchain technology in the field of taxation and VAT.[1] However, applying blockchain to taxation is often seen as something that is only possible in the long run, mainly because of scalability issues attributed to blockchain technology. In this blogpost, we clarify that the latter statement is not correct given the specific requirements in the field of taxation. We will first analyse the number of invoices sent within the European Union (EU), in order to estimate how many invoices per second an invoice reporting system should be able to process (this was not as easy as it sounds!

State secretary for the Interior Raymond Knops wrote in a letter to the Parliament: “My appeal to public services is to release the source code, unless they have good reasons not to”.[1] The usage of open source software has been increasing within governments all over the world.

To give people a better understanding of VAT and different VAT systems, we will start a new series of blog posts! In these articles, we will discuss VAT with experts from all over the world. These VAT specialists will give their perspective on the latest developments within the VAT world, specifically focusing on VAT fraud.

Governments all over the world have the same problem: there is a difference between the tax revenue collected and the tax revenue that should have been collected. This is called the tax gap. It is estimated that almost €1 trillion is lost on an annual basis within the European Union (EU) alone.[1] In this blogpost we’ll discuss the gaps of different types of taxes; import duties, personal income tax (PIT), corporate income tax (CIT), and value added tax (VAT).

During the last months, many governments announced economic rescue packages with a value of trillions of euros to tackle healthcare issues and related economic problems that the outbreak of the coronavirus is causing. These packages vary per country. However, all countries seem to agree on the fact that VAT adjustments can help.

For reliability we wanted to make our monitoring system highly-available, with two Prometheis and Alertmanagers on different machines, which meant that the Alertmanagers needed to be in cluster mode to talk to each other and de-duplicate alerts. This cluster traffic needs to be secured, and since we don’t use any kind of service mesh like Consul or Istio, our initial thought was to use mutual TLS between the Alertmanagers, which we can do fairly easily with our reverse proxy[1], Haproxy.

To illustrate this: every 39 seconds a cyber attack occurs in the US.

@Photo by Giammarco Boscaro on Unsplash Previously, we wrote about Value Added Tax (VAT) fraud. VAT is an excellent form of taxation as the responsibility to pay consumption taxes is distributed over the complete value chain, whilst only the end consumer actually pays taxes. This makes VAT a neutral form of taxation and to a certain extent both self-administering and self-policing. The rapid increase in the number of countries using a VAT system shows that the vast majority of countries agrees with the above.

At summitto we get to enjoy dependency management in C++ and more often than not, vendoring things using git submodules is the easiest solution to do this. However, submodules are not without their problems and nicer tools exist. In this blog post we’re going to look at two tools that are supposed to make our lives easier when working with git submodules. The shortcomings Before we start looking at the potential solution, let’s first quickly examine the problem.

Summitto created an explanatory video! Over the last couple of years, many people asked us “but how does TX++ actually work?” Blockchain is a relatively new technology and at times hard to understand. We tried to explain the benefits of blockchain in our last blogpost, but it is hard to know how these benefits are put into practice in TX++ in an article. To show people how TX++ works, we demonstrated our system in an operational environment on several occasions.
