Soft nodes and mainnet nodes will share in the total DAG reward pool for HGTP. The rewards for mainnet nodes will be weighted higher at a 60/40 ratio:

weight = 0.6 * [total mainnet nodes] + 0.4 * [total soft nodes]
​per mainnet node = (0.6 / weight) * total rewards
​per soft node = (0.4 / weight) * total rewards

The amount of total rewards accumulated will be dependent on the current parameters of the network and how many nodes are being operated.
