Blockchain is a neutral database. People in the cryptocurrency world tend to emphasize its distributed nature over neutrality. In computer science, distribution is merely a technical means to enhance or measure the robustness and resilience of a system or network. The number of nodes has little effect in terms of security; edges among nodes are what’s important.
Neutrality means that there is no conflict of interest among users. Let’s say there is an industry problem that competing companies mutually face. For example, intermediating payments among banks. To solve this problem, the industry needs a neutral player that can act as a middle-man by accepting data from these competing entities.
If Goldman Sachs wants to expand their business by becoming the middle-man, Bank of America won’t be using the service because they don’t want their competitor to become a platform which they rely upon. Instead, what the industry needs is another party, such as clearinghouses, that are free from the conflict of interest among banks.
Intermediaries exist to mitigate complexity in business interests. What intermediaries essentially do is to maintain a database for competing entities. We live in a world full of middle-man businesses. Payments between people are intermediated by banks. Payments between banks are intermediated by clearinghouses and central banks.
