The way of developing a blockchain-based application is to develop it using a popular existing blockchain platform. These blockchain platforms are open-source, so you can fork their repositories and deploy the code on your own servers. Few popular platforms are Ethereum, Hyperledger Fabric, and Hyperledger Sawtooth This step is very crucial. That's why you should take your proper time to design the blockchain instance. Step 6: Application Programming Interface (APIs) Now that you have your blockchain instance up and running, it is now time to manage the application programming interface(APIs). There are already pre-made APIs depending on the platform of your choice. This means that some platforms might not offer APIs at all Try dApp-browser and Ethereum-wallet on Android Try the test dApp, which receives messages from users and saves them in the blockchain. You can browse messages, sent by other users, and send yours. For sending messages to a smart-contract, you need to pay ETH for gas, required for sending the transaction Cut the 'blockchain' folder and the script and paste them in the 'app' folder in the main directory. Within the backend folder, we need to create the main script file
