How to publish data from one node to all other?
asked
I want to send some files or data to all other nodes or if possible to some specific nodes (like say gps location wise). How can i do this using DLT or anything else? 
It may be a silly question. Help will really be appreciated. Thank you in advance

this article on using IPFS to transfer files around on a blockchain. However, so far I am not sure if it is possible to limit the information you propagate in a network. Being able to share information to specific nodes would mean that the information distribution across the network is not uniform and can cause discrepancies in validation. However, using a concept of oracles and smart contracts you should be able to do something like that. But it voids to an extent the anonymity of the users hosting the node. It can be done but you can think about whether doing so over a blockchain makes sense or maybe rephrase your problem to see if blockchain can solve it. I hope that helps.
