Fees and VSPC(Virtual Selected Parent Chain)

No, in Kaspa each blue block receives a reward. The main reason is that rewarding only chain blocks (VSPC blocks) creates incentives for selfish mining.

But there are other (milder) advantages to being a chain block:

1. In GHOSTDAG ordering, it precedes any block in the same mergeset - therefore, if two blocks in the same mergeset have the same transaction, the chain block will receive its fees.
2. If it points to a red block, it will receive its reward. This rule has an exception: if the red block is outside the difficulty window, its reward will vanish (see more info here)
