Blockchain Development Guide: Build a Blockchain From Scratch

Blockchain technology is at the forefront of innovation making a massive influence on the industries and redefining the traditional methods around us. At present, blockchain technology is in the early phase that involves the creation and maintenance of decentralized, distributed systems. It helps us to tackle the problem with ease to improve its acceptance to the next level and also increase its deployment in almost every aspect.

In the early days, it was the platform that was used for supporting Bitcoin, blockchain exhibiting the quality of versatility and security started to impress many businesses to notice its ability and began to introduce it into their relevant field.

What is Blockchain Development?

Blockchain has been one of the major tech stories in the past few years. It is the type of database used to store data in the form of blocks linked together via cryptography which differs from the traditional database. This makes information easy for the computer to recognize the required data. This secured database is shared across a network of participants where the data is accessed by everyone at the same time.

Blockchain Development is the process of building a shared, immutable, distributed ledger system that securely stores the transactions and tracks the assets. Blockchain operates on a peer-to-peer network where no single entity has control, thus this decentralization enhances security and eliminates the need for intermediaries.

Prerequisites to Develop a Blockchain Network 

By having these prerequisites, it is easy to navigate the complexities of blockchain technology.

Network: As it operates on peer-to-peer networks, it is vital to understand the concept to ensure proper communication between nodes.

Cryptograph: It is a method of securing the data from tampering ensuring the integration.

Data Structure and Algorithms: It helps to strengthen your understanding of the problem wider scale and optimize the solution with the available constraints.

Decentralized Systems: Blockchain relies on the principle of decentralization where the authority is not controlled by a single entity.

Programming Language: It is essential to have some knowledge of coding to develop a blockchain network

Key Concepts to Consider to Make a Blockchain

It is important to learn about some basic concepts to program your blockchain

Cryptographic Hash and Digital Signature: Hashing is a program used to convert data into equivalent hexadecimal form and digi sign is the cryptographic output to check the authenticity.

Immutable Ledger: Data once entered cannot be altered.

P2P Network: It allows the user to make transactions between the nodes with the central server.

Consensus Algorithm:  It is an algorithm that brings agreement on the single data from all nodes of the blockchain.

Block Validation: It is a process where each node performs a series of tests to validate the transaction.

How to Build a Blockchain?

Building the Blockchain is time-consuming, and highly dependent on your distinct business requirements. Some of the key steps involved in developing a blockchain are:

Find Your Uses Cases

It is important to understand the concept of blockchain technology because this will change the way transactions are done in the upcoming years. So before starting to develop a blockchain, it is vital to find the use case that makes business sense. Things that blockchain can perform well are:

Data Authentication and Verification

Data, which includes digital signatures, immutable storage, and encryption, can be stored in any format in the blockchain. Blockchain can also build private-public key pairs used for developing and verifying digital signs.

Smart Asset Management

Smart assets that include issuance, payment, exchange, escrow, and retirement, are the tokenized form of a real-world asset like gold, or silver.

Smart Contracts

They digitally execute the agreement through self-executing code on the blockchain, thus mitigating the losses of risks with the secured and transparent mechanism.

Draft Your Business Requirements

After finding your business needs, draft a detailed plan to define the technology requirements for your business. This information will help to sketch the basic product map to make sure that you meet your deadlines and understand the resource needs.

Identify a Suitable Consensus Mechanism

A consensus mechanism is a program that helps to attain the distributed agreement on the current state of the ledger. Primarily, Proof of Work(PoW) is used as a consensus mechanism in the blockchain technology that powers the bitcoin. 

But today there are multiple groups of consensus mechanisms available, so choose the apt algorithm according to your business needs. Some of the available mechanisms are:

1. Proof of Stake (PoS) 

2. Delegated Proof of Stake (DPoS)

3. Proof of Elapsed Time (PoET)

4. Proof of Importance (PoI)

5. Proof of Capacity (PoC)

6. Proof of Weight (PoWeight)

7. Proof of Activity (PoA)

8. Practical Byzantine Fault Tolerance (PBFT)

9. Simplified Byzantine Fault Tolerance (SBFT)

10. Directed Acyclic Graphs (DAG)

Tangle & more.

Choose The Suitable Blockchain Platform

Today there are many distributed ledger systems available, most of which are free and open-source. Depending on the consensus mechanism chosen from the above step, precisely choose the suitable platform that fits your business needs. Some of the platforms available are:

Design The Nodes

Determine whether your blockchain network is constructed as a permission or permissionless network.

The permissionless network is where anyone can join and begin to verify which includes Bitcoin and Ethereum networks. The permission network is where the network owner approves the members who can join and only a few have access to verify the blocks.

It can also be private, such as the contract-based management system in a healthcare firm, public like the Bitcoin platform, or hybrid such as a group of banks functioning on the shared KYC.

Additionally,  to determine the hardware configuration issues like processor, memory, or disc space, determine whether the node will run on the cloud, on-premises, or both.

Plan Blockchain Configuration

For most blockchain platforms, it's essential to strategize for various configuration elements. Some elements can be modified during runtime while some cannot, so this is a crucial step to consider. Some of the elements are the following:

1. Permissions

2. Asset issuance

3. Asset re-issuance

4. Atomic exchanges

5. Key management

6. Multi-signatures

7. Native assets

8. Address formats

9. Key formats

10. Block signatures

Build the APIs

Most of the immutable blockchain platforms come with pre-build APIs whereas some don’t. So per your requirements, you may need the following to build an API:

1. Production of key pairs and addresses

2. Performance of audit-related functions

3. Data authentication (through digital signatures and hashes)

4. Data storage and retrieval

5. Smart-asset lifecycle management

6. Smart contracts

Testing and Quality Assurance In Blockchain 

Test your blockchain thoroughly to identify and fix bugs or vulnerabilities and also set up a test net to simulate real-world conditions.

While developing the blockchain network, make sure that the quality check goes hand in hand with the coding which means that  QA engineers have to work following the developers to catch and fix the issues early on.

Deployment and Integration

Once the blockchain passes testing, start deploying it in the live blockchain network where developers do containerization of blockchain components.

They also facilitate the integration between the blockchain and standard software infrastructure. The final stage involves the actual testing of the network in collaboration with clients. Following this, it is necessary to integrate the additional needs of clients before launching the networks.

Maintain and Update the Network

Maintaining and updating a blockchain network involves regular monitoring, security audits, timely software updates, and scaling solutions as needed. Backups and recovery processes must be done on a timely basis and also smart contracts must be updated periodically.

Ensure that the team is trained on emerging technologies and security practices and also maintain the testing environment for updates. Being updated helps us to stay in the current trend.
