It is random, every miner with at least one recall block has a chance to earn rewards the same as everyone else, assuming they have a good enough internet connection to download at least part of the block in time.

Ok cool,

Is there the whitepaper already? Because now I have more questions :)

Is this abuse safe? if someone split a server into different Wallets for more tickets to provide the minimum needed, for block rewards?

Or is there a rewards mechanic to rent a big boy to give many resources to the network for rewards?

Random eh? As far as I know the only way to create random number lotteries in crypto is via POW mining. I guess I should do more research on node consensus via POS networks. Looking forward to the whitepaper.
