I am a noob at this. When a miner get an accepted share and got a Node in the network (from normal node to shard backup or backup node), I assume it will get a reward. The second time the miner get an accepted share (next 00 block), is this trying to get the node into becoming a DS Node?
Secondly, if my node is already a shard backup or backup node, why do I need to mine to that node again? Wouldn’t the 2/3 rewards keep giving the node free rewards for getting into the network the first time?
