Are full nodes going to be incentivized with block rewards?[/b]

Yes. Anyone that runs a full node and participates in the network node funds allocation program will receive their share of 3.43% of the coinbase rewards. Additionally one of the functions of the DAO will be to maintain network node size and may allocate additional funds to node operators.

The Zen network target size is to be at least 1,000 fully operational nodes. At this size at least 7.40 zen will be rewarded to each node operator. In the event the Zen network size has not been reached the DAO may allocate some of its discretionary funds to encourage node deployment.
