It's not relatively new. That “transaction file” thing in your database? Event Sourcing.

I disagree. Not having a single point of failure (one place that can get hacked) is valuable.

Of course it does. The protocol of blockchains makes them work with "proof of X". Appending to any event store, whether in Kafka or SQL does not require proof of anything.
> Blockchains are built for trust, databases for throughput. Event sourcing allows us to achieve a hybrid model with characteristics of both.
No, the reason blockchains can't have high throughpout / almost infinite horizontal scalability... is because there's a logic check. E.g. in bitcoin, you can't send more bitcoins than you have a balance. Event sourcing gives you the high throughpout if there's no logic checks across aggregates --- if there are, you won't have immediate consistency, and you have to be ready for compensating events.
I recommend two books, that cover event sourcing from a Domain Driven Design perspective. The consequences are similar.
If that doesn't do it for you, please just remember the good old CAP theorem.
