Are There any Prerequisites to Developing a Blockchain app?

· Dapp browsers include desktop Mist, Parity, Metamask and mobile versions include Toshi, Cipher and Trust

· The Solidity to allow smart contracts

· Open Zepplin: smart contract development

· Embark: Framework for serverless, decentralized applications that utilize Ethereum, IPFS and other platforms

· Truffle: The most loved Ethereum framework for testing and development.

· Metamask: to run Ethereum dApps within your browser, without having to run an entire Ethereum node

· Parity: the most modern Ethereum deployment client

· Etherscan: Block Explorer on Ethereum to monitor

Apart from the frameworks mentioned above, normal frameworks can also be used for server and app development, such as react.js, NodeJS and native technologies to develop mobile apps.

Development

This is the primary aspect of developing blockchain applications. To simplify things, we’ll follow the steps as described in 2c. above i.e. using tokens that are already on blockchain platforms. It is essential to know the mechanism of transactions first.

Token is an alphanumeric string that acts as an identifier unique to your smart contract/coin. Every user of blockchain wallets has their own private and public key (similar with lengthy passwords). The keys identify users who are able to debit or credit their funds, or to indicate the address of the smart contract towards. This is similar, however it is much safer, as compared to the process of adding a new beneficiary to your bank account by using their bank account numbers.

You are able to create your own smart contracts or token using the Solidity language that is compatible with Ethereum. First, you should create a test token to check its functionality before placing it on a actual blockchain. Use this guide on how to create your very first Ethereum token, and read this blog post to learn the intricacies of making the token of your choice. After you have created the contract or token and then put the token “on the chain” which is essentially referring to the same thing as placing your code to the server.

The transaction begins by one person sending an intention to distribute a token, which is then confirmed by the network to be valid (if you are the owner of the token and haven’t given the token to any other person). The token’s information is coupled with your private key that then generates an electronic code that is later confirmed by the network by using that sender’s private key. This is possible due to the fact that contracts signed with private key is valid by using public keys, but there is no connection between public and private keys can be determined, and so the information is safe.

In essence, the entire procedure is similar to decryption and encryption. The decentralization of information and the incorporation of history of blocks to secure it makes it safe and secure.

Additionally, you’ll also build APIs for:

· Auditing and performing functions.

· Retrieving and storage of data.

· Generating keys in pairs as well as mapping these keys to particular addresses.

· Data authentication is performed with the aid of hashes and digital signatures.

· Controlling and triggering of smart contracts that run the features of a business application.

The Key Takeaway

This is also the conclusion of our building an application for blockchain. This is the process of creating an application for blockchain development from scratch.

In the next step, you will need to test the contract thoroughly before you move it to blockchain. You could also build the front-end to the app and try it out. If you’re not keen on doing this, it is possible to fire up the console and gain access to the variables and functions to try things out!

However, if you’re not fully aware of the benefits of blockchain technology, then we recommend that you begin our blockchain course for free to understand more about the technology. If you do not know how it works, understanding the concepts of programming will be difficult for you.
