Inefficiencies are often perpetuated not by a lack of technology, but by (historical) structures. Blockchain technology is therefore not a patent solution for change, but it does provide an opportunity to make change.
Disruptive technologies require time to develop, mature and unfurl their full potential. Not every innovation succeeds, though, and it remains to be seen how the application of blockchain technology will develop.
Following the revolutionary beginnings with bitcoin, the prevailing view now seems to be that blockchain applications will spread rather more gradually. One might therefore speak of evolution rather than revolution. Before we can even ask questions about the broader use of this technology, we must first be sure that using this new technology is at least as secure, efficient and cost-effective in financial transactions as conventional technology.
Blockchain technology could become a game changer, in the financial industry and, perhaps in particular, beyond. The potential of blockchain technology is often compared to that of the internet. It should be remembered that it took some time before the truly beneficial applications of the internet emerged. With blockchain, we are only at the very beginning of a potential development of this kind.
Innovations are the lifeblood of a continually developing economy. Moreover, evolution processes are never linear. The first great wave of euphoria, which was also seen in the media, is being followed by a phase of checking, weighing-up and consolidation, before new offers and technologies are rolled out on a broad scale.
Ladies and gentlemen, Goethe once said: "We know accurately only when we know little; with knowledge doubt increases."
My impression is that with the increasing efforts being devoted to blockchain technology, doubts will also increase as to whether this technology can meet the expectations being placed on it, which in some cases are extremely high. The question that we want to examine in more detail in this workshop is what specific doubts we have and whether the technology can overcome them.
