How to Develop Blockchain: Step by Step Guide

Blockchain technology is making the future transparent by disrupting various industries and is now considered the essential part of secure, transparent, and decentralized systems. If you want to create your blockchain for a specific use case, you’ve come to the right place. In this comprehensive guide, we’ll navigate you through some steps that are necessary to develop blockchain. Whether you’re a blockchain enthusiast, developer, or business owner exploring blockchain applications, this guide will provide you with authentic, valuable insights with practical knowledge.

Blockchain Overview

A decentralized, distributed digital database that maintains a continuously growing list of ordered records, called blocks. These blocks when linked together using cryptography, contain a hash of the previous block → a time stamp, and transaction data.  → This means anything that is added to a blockchain cannot be altered and becomes immutable. Before delving into the steps to develop blockchain, you should know how is blockchain different from traditional database models.

How to Develop Blockchain: Step-By-Step

By getting into the details, you can make informed decisions regarding your blockchain development. The below steps are essential to lay a strong foundation for successful blockchain development.

Step 1: Define Your Objectives

• Firstly, determine the specific industry or use case for which you are developing the blockchain. Whether it’s supply chain, finance, healthcare, or any other sector, your objectives must align with the industry’s unique needs.
• Secondly, define the exact use case or problem you intend to solve with the blockchain. For example, in supply chain management, your goal might be to enhance transparency and traceability.
• Thirdly, identify the primary users and stakeholders who will interact with the blockchain. Are you targeting consumers, businesses, or both?
• Lastly, establish measurable KPIs to assess the success of your blockchain. This could include transaction speed, security, cost savings, or user adoption rates.

Step 2: Choose the Right Consensus Algorithm

• Proof of Work (PoW): If you select PoW, be aware that it requires substantial computational power and energy. It’s known for its security and decentralization but can be slower and resource-intensive.
• Proof of Stake (PoS): PoS is more energy-efficient and scalable, making it a good choice for certain use cases. However, it may lack the same level of security as PoW.
• Other Consensus Algorithms: Depending on your requirements, you might consider alternative consensus mechanisms like Delegated Proof of Stake (DPoS), Practical Byzantine Fault Tolerance (PBFT), or others. Research these options thoroughly to make an informed choice.
• Security Considerations: Different consensus mechanisms offer varying levels of security. Ensure the mechanism you choose aligns with the security needs of your project. For instance, financial applications demand a higher level of security compared to a supply chain use case.
• Scalability: You should assess how scalable the consensus mechanism is that you have chosen because scalability is a priority, especially if your blockchain is expected to handle a high volume of transactions.

Step 3: Pick the Ideal Blockchain Platform

First of all, consider your requirements as your choice should be influenced by the specific needs of your project. For example, if you’re building a public, decentralized application, Ethereum might be ideal. If you’re an enterprise focusing on supply chain transparency, Hyperledger Fabric could be a better fit. Here are some of the examples listed below; 

• Ethereum: If you’re looking for a widely adopted platform with smart contract capabilities, Ethereum is a strong contender. It’s the go-to choice for decentralized applications (DApps) and offers a vibrant developer community. However, it may face scalability challenges due to its Proof of Work (PoW) consensus.
• Hyperledger: Hyperledger provides a range of frameworks designed for enterprise applications. It’s a solid choice for businesses looking to implement private or consortium blockchains. Hyperledger Fabric, for instance, offers robust permissioned blockchain solutions.
• Binance Smart Chain (BSC): BSC is known for its high speed and low transaction costs, making it suitable for DeFi projects and applications that require fast execution. It’s a fork of Ethereum, which means it’s compatible with the Ethereum Virtual Machine (EVM).

Step 4: Design the Data Structure

We have listed some aspects that should be addressed through the process of selecting the ideal blockchain platform and designing the data structure, crucial elements in the development journey. These steps are fundamental to ensuring your blockchain aligns with your project’s objectives and performs efficiently.

• Data Organization: It is the time to make the right choices like how data will be structured within blocks. You’ll need to decide on the format for transactions, including the data they will contain and how they’ll be validated.
• Storage Mechanism: Consider the storage mechanism for your blockchain. Will you use a relational database or a NoSQL database? This decision impacts data retrieval speed and overall performance.
• Linking Blocks: Describe how blocks will be linked to form a chain. Explain the concept of hashing and how each block’s hash is based on the previous block’s data, creating a secure and unchangeable record.
• Efficiency and Security: Emphasize that a well-designed data structure ensures the blockchain’s efficiency and security. It enables quick data retrieval and, most importantly, safeguards against fraudulent activity.

Step 5: Develop Smart Contracts

Smart contracts are the building blocks of a blockchain. For developers alike, this step involves writing code that defines the rules and conditions of a contract. Here’s a more detailed explanation:

• Coding Languages: You should select the appropriate coding language for your smart contracts. Ethereum, for instance, uses Solidity, while other blockchains have their own languages like Chaincode for Hyperledger Fabric.
• Automation: Describe how smart contracts automate processes and transactions, removing the need for intermediaries and reducing the risk of errors or fraud. Use real-life examples to illustrate their practical applications.
• Testing: Emphasize the significance of testing your smart contracts rigorously. Any vulnerabilities or bugs in a smart contract can have catastrophic consequences, and thorough testing is essential to prevent these issues.

Step 6: Ensure Security and Scalability

There are ways to ensure the scalability and security of smart contracts and security is our priority; 

• Security Best Practices: Highlight the importance of implementing security best practices, such as code audits, secure development standards, and the use of secure libraries. Security breaches can lead to significant financial losses and reputational damage.
• Scalability Solutions: Explain the challenges associated with blockchain scalability, particularly for platforms like Ethereum. Mention potential solutions, like layer 2 scaling solutions (e.g., Optimistic Rollups) or sharding, and how they address these challenges.
• Consensus Mechanism’s Role: The chosen consensus mechanism (mentioned in Step 2) can impact both security and scalability so you need to discuss it. For example, PoW offers robust security but may suffer from scalability limitations.

Step 7: Test and Debug

The testing and debugging phase is where the rubber meets the road. First of all, perform all kinds of testing or what you want to do, Here’s how you can do it; 

• Identifying and Resolving Issues: Emphasize that the purpose of testing is to uncover issues and bugs. Elaborate on how developers must identify, prioritize, and resolve these issues promptly to ensure the blockchain functions correctly and securely.

Step 8: Launch Your Blockchain

The launch phase is a significant milestone. Here’s how you can provide more insights into this step:

• Public vs. Private: Discuss the differences between public and private blockchains. Public blockchains are open to anyone and often used for cryptocurrencies, while private blockchains are restricted to a specific group and commonly used in enterprise settings.
• Infrastructure Setup: Explain the technical setup required for the launch, including nodes, network configuration, and consensus mechanism activation. Mention that the choice of blockchain platform (Step 3) plays a vital role in this setup.
• Deployment Strategies: Address deployment strategies, such as a phased rollout to mitigate risks. Highlight the importance of monitoring and maintenance post-launch to ensure the blockchain’s continuous operation.
