Hi, my name is Rohit, right now I am working on my thesis for developing Dapp, to provide the decentralized secure database, for the storage of data I came across ethereum blockchain which provides the solution but regardless, executing the smart contracts to store the data, however, consumes a token. It needs a wallet which in turn complicates the use of the app for the users. So is there an option in blockchain to execute it and not making it heavy for the users. A bit confused on the selection, so the option for other databases like OrbitDb and BigchainDb or Gun. How can I achieve the things incase of ethereum-go instead, to do the same work along with encryption without tokens?
Yes, the biggest barrier for Dapps (or decentralized apps) is the requirement for users to sign every transaction with a private key. Most users just want to use username / password, and do not wish to do the chores of private key management. That is why most dapps you see today are "money" related -- investment, gambling etc. There are really two ways to mitigate this. We discussed both options at length in the book. https://www.buildingblockchainapps.com/
1. Build key management into your client. That is, to provide a "wallet" in your web app or mobile app and help the user access the key transparently once they login.
2. Automatically generate keys for public apps. This approach is essentially what you see when you create and publish a Dapp from the BUIDL IDE tool:
