Node operators are a valuable part of the xx ecosystem. Nodes receive a share of the reward generated for each block. Assuming that each node performs well in every role it plays, then, over time, the network will allocate the same amount of block rewards to each node. This is due to the random selection of nodes participating in mixing, endorser, and block producer teams. However, if nodes do not perform well, they will be penalized and lose some, or all, of the block rewards that they would normally earn.
