Looking at the ANN, it shows that the final product isn't expected to be available until 2019. If there will only be Alpha and Beta testing in 2018, will you be paying the miners thaty are helping to test your software in the early stages?
Thanks for your question.
We are happy to announce that our Beta Version of the Leonardo Render software is on the way. Many improvements and stability tests have been made. The Beta version will be accessible via free download and the rendering service will be available for free for the duration of the Beta-Stage. Stay Tuned for more info.
Best,
