Events

[domwoe]

On the EVM, developers are used to generate events in their smart contracts to which clients can subscribe.

On ICP, there's no platform-level support for such a mechanism. Still, we could implement a similar mechanism on the application level, and I'd like to discuss if this could be a beneficial addition to this CDK.

The general idea would be to have a certified log with events stored in stable memory together with an API to e.g. retrieve the N latest events by type (to be discussed).

In addition, the websocket project could be used to allow subscribing to events.
