The author of Microservice Architecture Patterns, @cer has given a presentation on Event Sourcing with a Money Transfer application example: https://plainoldobjects.com/presentations/building-and-deploying-microservices-with-event-sourcing-cqrs-and-docker/
This is the GitHub example: https://github.com/cer/event-sourcing-examples
If enough contributors think this was an interesting idea, it would be a nice showcase for both JavaMoney/JSR 354 and other technologies including MicroProfile, JNoSQL (MongoDB) or Docker.
