Simplest DApp is a simple DApp on Nervos CKB which allow user to create, update and delete cell data.
Simplest DApp is an example for Nervos CKB developers to start to develop their own DApps.
Simplest DApp never touch users' private keys and it's all operations which need private keys will delegate Keypering to complement. Keypering is a desktop wallet that manages user's private keys and lock scripts and responds to requests from DApps.
For example, when Simplest DApp need to sign transaction, it will send request to Keypering and delegate it to sign transaction with its' private keys and return signed transaction to Simplest DApp.
