How Does Blockchain Development Work

A "blockchain" is essentially a set of time-stamped "blocks" consisting of digital data encrypted with a special hash function. This data can be in the form of files, transactions, or simply certain information. In a blockchain ledger, it is arranged by three categories: data regarding transactions, data regarding the participants, and unique information (hash) specific to each block that distinguishes them from each other. The database for this information is shared among a group of computers forming a network or a “chain”, associated with the particular information in the ledger. 

Every blockchain adheres to a set of rules befitting to it. Typically, a large number of computers (“nodes”) that function on a peer-to-peer basis verify all inbound data before storing them in the ledger, thus making blockchain development decentralised. A blockchain record is unchangeable, timeless, and secured by numerous levels of cryptography. Furthermore, regardless of the fact that all operations on a blockchain network are completely public, it protects the identification of its network participants by offering total anonymity.

In a nutshell, this is how a blockchain transaction operates:

Someone requests a transaction, which is represented as a block. This contains the current hash and the hash of previous block and data. Now this block is broadcast to all the members of the network and they use the rules of the particular blockchain to validate the transaction. Once a consensus is reached about its legitimacy, the block is added to the chain and the miners are rewarded by using tokens specific to the blockchain platform. The shared ledger is then updated and the information is automatically shared among all network members. 

How does blockchain development work?

Blockchain technology can be incorporated in literally every discipline you can think of - it only streamlines the operations in the field for the better. From healthcare and telecommunications to real estate, media, and finance - blockchain solutions facilitate every arena. Blockchain development companies use the following steps for the procedure of blockchain development and integration:

  1. First, the problem or goal is identified:
    Prior to delving deeper into the blockchain development process, it's critical to first identify the problem statement. You should know precisely how your company will benefit from blockchain development services along with what problems the suggested approach is supposed to answer at this point of your business. To exemplify, if you're a food supplier interested in developing a blockchain-based supply chain app, you should be aware of the app's various use-cases and how they will help your company and consumers.
     
  2. Then it is time to decide the suitable blockchain platform to build the programme:
    To create a decentralised application without needing to create a blockchain from zero, you'll need a readymade blockchain framework. The following step is to identify the best blockchain platform for your project once you've determined that your organisation requires a blockchain-based solution. Your choice will be determined by the consensus protocol and the issues you'll be addressing. Ethereum, Hyperledger Fabric, Hyperledger SawTooth are few such popular systems. Each one has distinct qualities that can assist you in making your pick.
     
  3.  After that, business ideas and requirements need to be discussed and determined:
    The blockchain development company that you hire should be guiding you for assessing, formulating, and prioritising use cases for blockchain experimentation at this stage of the blockchain development process. You must also pick which parts of the app will be "on-chain" and which will be "off-chain", meaning which parts of your web app or mobile app will have blockchain integration and which will run normally on a general cloud hosting, respectively. After that, you will need to prepare a product roadmap, including when an alpha, beta, and ready-to-launch version of the app will be released.

    Another important decision to make is which section(s) of your application should be permissionless and which component(s) should be permissioned. In a permissioned blockchain, everyone on the network can join with no restriction and gets involved in the verification process. On the other hand, permissioned blockchain allows only a few users to verify blocks and the network owner determines who can join the network. The consensus techniques for the two networks can be similar or completely different, depending on the conclusion you arrive at in collaboration with your trusted blockchain development services team.
     
  4. Only after all this is completed, a proof-of-concept (consensus) is created:
    A proof-of-concept is a technique to illustrate a blockchain project's practical viability. It can be either a theoretical construct or a prototype. For this, first proposals are created to explain the viability and predictability of the project to the end-user. It's also crucial to document the technical GDPR compliance requirements so that you know where it should be implemented. 
     
  5. Finally, your product is developed:
    After completing the theoretical build-up and collecting input from all stakeholders, a prototype is developed incorporating sketches, information architecture, mockups, designs, and a tested product. Here, many blockchain development companies suggest the creation of one’s own tokens/smart contract. After creating it and putting it “on the chain”, your code is essentially deployed on a server.

    Then user interfaces are created for every part of the software and APIs that can be combined with user interfaces are built in order to execute the programme on the back-end before proceeding to the development process. APIs are developed to perform auditing functions, data storage and retrieval, to create key pairs and assign them to certain addresses, to use hashes and digital signatures for data authentication, and/or to coordinate and activate smart contracts to power an application's business capabilities. Overall, blockchain development companies advise you to make the application capable of scaling up and down as per the evolution of company needs and priorities.

Conclusion

Making smart contracts “smarter,” ensuring that your coins are unhackable, or at the very least incredibly tough to hack into, and so on are all highly challenging tasks. You can create a minimal functional product for your blockchain-based application by following the steps above. However, to build a really great application with the integration of blockchain, you will need the help of reputed and experienced blockchain development services that will guide you throughout the way.
