I'm positive it's used in crypto, but there's nothing novel about append only logs. It just means you don't remove the old stuff.

To elaborate a bit, crypto is backed by tokens specifically to ensure integrity in a distributed network (on machines you don't own)

If you own the DB you don't need this.

Of course you can pay for each new log entry using crypto tokens, but you don't have to.

You can use an open source version of AOL (Append-Only Log) SW for free, alternatively you can use a managed cloud version, but there you will have to pay with something called USD which is a social construct 1:1 pegged to a crypto-tokens like Tether USDT, MakerDAO DAI, and other so called "stablecoins" ;)
