Many of you have probably questioned the usefulness of blockchain in general and Ethereum in particular. Some of you may have gone further in your curiosity and came across numerous fancy characteristics, such as decentralization, transparency, trust without intermediaries, and hack resistance. That’s remarkable, isn’t it? It sure is, but…
In its current state, blockchain is a perfect match for fulfilling a narrow range of tasks, unless you consider “adding some nanotechnologies for a wow effect” to be a task – in fact, you can adjust nearly anything to align with this objective. Of course, something needs to be done for a start, with various experiments helping understand the potential and showing where the demand can be, where an unexpected dead end is, and where the drawbacks turn out not as critical as predicted. You do need to know about the boundaries, though, in order to make an informed decision whether it’s reasonable to try and step over them in a particular scenario.
