After discussing how to solve the data blob signing issue and complexities, we decided to go a different route and let every legit pop participant (registered machines) ask for an explicit receive address so that the RDDLS can be sent there. The service will store the relation between the receiving address and the machine (planetmint address).
After receiving the RDDL tokens on the address, the mint request will be issued, and the address will be disregarded and not be used again.
