There are various crypto's that reward staking by keeping your wallet open and there are crypto's like SIA, MaidSafe, Burst that offer reward for storage capacity. However, I am not aware of any crypto-projects that offer the opportunity to get rewarded through staking traffic? I have plenty of bandwith to offer, which is not used most of the time.
It's this the same concept as we saw in Freenet? Never used it but supposedly everyone stored everyone else's data encrypted, and then it would be impossible to stop the network since every computer would be a node, similar to Bitcoin nodes storing the blockchain, but without proof of work involved.
If Core devs didn't entertain this idea im sure there are big problems with it. I remember Maidsafe never delivered on its promised thus far..
