I think we should copy along (maybe edit the first post on this topic), the “Motivation” for this incentivised testnet, from @Adamefr 's initial post in November:
There’s also another reply by @alonmuroch on the V3 version, about one of the objectives…
It is clear to me that this incentivised testnet is very ambitious, with a broad spectrum of objectives, and these objectives need more visibility.
I am in favor of LAUNCHING IT as soon as possible.
The team needs feedback.
Codebase needs to be tested in as many scenarios as possible.
The interaction between validators and operators also needs to be tested.
The network economics is a huge factor, and I think it cannot be really tested without an incentivised testnet.
While this may not be perfect, IMHO, launching it will greatly benefit the project.
