I am new to Ethereum.
We are planning to use Ethereum for building an application where-in we don't want the users to buy and use Ether's. We want the user's to safely store and retrieve / share the information in the Ethereum Blockchain.
I have explored on the basics of Gas and their reduction for each step of execution in the SmartContract.
However, I would like to know if I can use the platform without requiring the user's to buy Ether and submit their data for sharing / storage. Also note that, I am planning to try out building an application that uses 0 Gas and 0 GasPrice.
I have read this question to be relevant, but the user wants to run in the local system, where as I would like to have it hosted in Ethereum network and make it available for public use.
