Jumping on a blockchain thread to ask this question-

Can anyone imagine ANY uses for a centralized blockchain?

IOTA uses tangle, but the idea is the same. Storing immutable data.

I understand Bitcoin, people commit currency fraud. Bitcoin is decentralized. Trustless currency sounds fantastic.

I do not understand these data coins that are centralized. It isnt trustless, and at this point, why not store in a write only sql database?
