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. They are huge and specific problems.
Nevertheless, there are industry people saying that “blockchain immutability” is the biggest problem of a blockchain.
And so we have tons of blockchain/alter-coins, but “centralized” or “owned” by someone. But if I need to trust “someone”, why using a blockchain system in the first place! Just use a damn distributed database!
