Err… what? Is any database now a centralized blockchain? I don‘t even get from the sentence that this is using any kind of cryptographic verification (though it might).

I think we can probably think more along the lines of the postgres wal (write ahead log) and _journaling_ file systems here.

I think a lot of younger people and crypto-influenced people today think of "journaling" as "like a blockchain" based on the overlaps (not the cryptographic portion, the "blocks" half).

I dislike crypto and have argued against it many times just on this site. But other than financial audit DBs, I haven’t seen many use cases for a cryptographic ledger db. AWS’s own ledger DB, QLDB, was discussed in the context of blockchains on HN when it was announced several years ago.
