I'm only getting started with my knowledge of Blockchains, but one thing has me confused.
If I were to build a Dapp offering a service for users, such that users don't have to pay to use the service, how can the transaction fees from executing the computation be paid for?
If a way around this was to only show data (i.e. so nothing is being written to the Blockchain, only read), would that have a computation cost? Does reading data count as a transaction?
Thank you in advance for your help. Please don't hesitate to correct any of the above.
