@theAusicist I looked into what you reported around block gas limit with the core team and they say that this is expected. Later we will charge the user for storage in a separate way and it will be not mixed with the gas so you won’t be having these issues. Plus, we won’t be allowing 17MB contracts later on, it is too much.
