From my understanding, PIX tokens will be used for both of these. Look at the [ANN] thread and the WP:

To grow a database with over one billion datasets, we determined that the most effective approach is to use PIX tokens as a form of compensation for contribution. PIX tokens will be used to pay miners and voters for their contributions. There are many modules used in the architecture of the Lampix device and database ecosystem. A few include the data storage database, gateway and data submission, and smart contract for voting module.
