The fourth session of the workshop took place unusually just a week after the third one. Actually, it was an unusual workshop : instead of having just me presenting a concept and then explaining how to use it, we started with 2 short presentations.

The first by Patrick Guillaud which was about Bitcoin as a digital object, and the second by Thibaut Tauveron about Docker and how he created the Insacoin Docker images. I then explained how to handcraft Insacoin transactions but we had a slight problem with network connection…

Bitcoin as a digital object

In this presentation Patrick, which has been using Bitcoin for more than 7 years, presented it from another point of view : an object-oriented view. He started by defining the characteristics of a physical (tangible) object and then applied it to a bitcoin (without the capital “B”, I’m talking about the token). He explained that a bitcoin has all the properties of an object, and even more. What if Satoshi, with Bitcoin, also created the first tangible digital object ?

Insacoin in a Docker container

Here is the presentation (in french) of Thibaut, the “how to” has already been detailed in “How to use Insacoin with Docker”.

Hand-made raw transactions

I have already written a whole post about it on Medium so I won’t copy/paste it here nor I will rephrase it.
