A skeptic’s take on blockchain:
Each purported use case — from payments to legal documents, from escrow to voting systems—amounts to a set of contortions to add a distributed, encrypted, anonymous ledger where none was needed. What if there isn’t actually any use for a distributed ledger at all? What if, ten years after it was invented, the reason nobody has adopted a distributed ledger at scale is because nobody wants it?
It is easy being a skeptic, and it is easier being a believer. What is hard is being patient to see how things unfold. Everyone is using obvious examples but what if the use cases come in more mundane forms? I have seen time and time again, that use cases come in the non-obvious places. Same will be true for Blockchain.
