Small rant about "blockchain" overuse
A lot of startups are using “blockchain” as a replacement hyped word for “distributed database”. Well, a blockchain is the most inefficient and slow “distributed database” ever created. Blockchain strength is not in being a database! Stop doing that! The blockchain power is in avoiding divergent transactions, and guarantee a not falsifiable and immutable history. That is, no node in the system can alter the past of the chain. That’s it.
