Yeah blockchain seems like overkill here.
But the world of corporatism is just as susceptible to fads like every other subculture.
It's like execs are desperate to force blockchain on every problem because it's the hip new thing. Even though most problems don't need blockchains and there are far better and simpler solutions.
Similar to the nosql fad. Who needs ACID compliance? If things fail silently and we lose a few transactions here and there, what could go wrong? Get with the times. The cool kids are into nosql now.
