Wall Street rethinks blockchain projects as euphoria meets reality
What does &quot;blockchain&quot; even mean in this generalised context? When we are talking about crypto currencies, it is a distributed database with a consensus mechanism that is extremely costly to run. But this is not something you would need or want in most other situations, because there is always some degree of trust with your counterparties (and legal recourse if necessary).<p>If we strip away the consensus mechanism, all that is left is a trivial data structure that anyone with a CS background could come up with. So, the question becomes where the real value proposition is in &quot;blockchain technology&quot; outside of the realm of crypto currencies. What are the things you can only do with &quot;blockchain technology&quot; that cannot be achieved with existing technology? It looks more like a marketing buzzword than anything that has actual merit for the average use case.
