I haven’t written up any of the production work I’ve done in this vein, but here’s a demo application I built as a hiring challenge (apologies for the broken demo link, it was hosted by the now-defunct Hyper.sh): https://github.com/notduncansmith/agree/blob/master/README.m...

Given no firm deadline, I timeboxed to 12 hours so it’s not fully fleshed-out but I like to think it illustrates the concept well.

Ah, that's cool! I like your writeup; it makes the advantages of your approach clear. I hope you got the job!

Thanks! I did, though now working at another co and spending my free time generalizing this into a library that makes this paradigm easier to adopt (basically Redux-ifying your backend but with end-to-end encryption on the stored event logs). The initial version should be ready to publish in the next few weeks :)

If you remember, please email me or contact me on Twitter when it comes out! I'd love to check it out. And I'll definitely pass it along to the Prevayler community, who I'm sure will be tickled.
