Sometimes I think "DASH" has some kind of advantage over Bitcoin because it has some rewards not just for the miners, also for the full nodes. Am I correct? Is not this a strength (a prevention) against Sybil attacks?

Does anyone ever thought of any kind of "payback" that could reward the bitcoin full nodes with satoshis trough the lightning network? Maybe just a fraction of the block reward could be distributed to the full node network.

I'm newbie, but the reducing number of full nodes due to the increasing size of the blockchain (or other attacks/technical difficulties) scares me.

Thank you.

    A users ‘reward’ for running a full node is their sovereignty. This is valuable, even if it is a somewhat intangible value. Otherwise, a Sybil attack is precisely the reason why rewarding full nodes isn’t tenable: what’s to stop me from running a million nodes and gaining a million such rewards? Miners must expend energy in order to be ‘rewarded’, the same is not true of full nodes. – chytrik Mar 1 at 4:32

    Nor is "more full nodes" something desirable on itself. Certainly the ecosystem is helped by having a large number of independent full node users (people whose economic activity is verified by independently-run nodes), but this is not something that can be measured. How many full nodes do you need? One, your own. – Pieter Wuille Mar 3 at 19:53

Dash does not reward full-nodes, it rewards so called "masternodes", which are nodes that hold at least 1000 Dash. At one point, that was worth 1.5 Million dollars. It is a way to encourage long-term investment. The masternodes also get to vote on how 10% of the block reward are spent. This is used to pay for development of the software and to fund projects.

Bitcoin can't have such a system, as there is almost no capital required to set up a node. It would be easy to run 1000+ nodes on a decent server, without helping the network more than a single node would, but I would still receive 1000x the reward every normal node operator receives.
