There is a difference between the knowledge of individuals and knowledge of institutions. Many people who seriously looked into these things said it was bogus. But the institutions didn't know it was bogus. They didn't know whether to believe the nay-sayers or not. So "our" (for some weird abstract sense of "our") knowledge increased by doing these doomed experiments.

Wal-Mart and Louis Vuitton both announced they were adopting blockchain. Walmart's was for supply chain tracking of lettuce. LV's was for authenticating genuineness and preventing sales of counterfeits. Both were to be run entirely by the company. Centralized. No distributed anything.

There was no reason to use blockchain in these cases, except that writing a press release about blockchain would cause a stock price pop.
