Public Blockchain Vs. Private Blockchain-A Comprehensive Guide


Have you ever wondered what is the main reason why people use blockchain technology? The point is that it creates a high level of trust to protect your data and processes in a secure network. Since the founding of Bitcoin by Satoshi Nakamoto in 2008, blockchain technology has disrupted every industry as it has been rapidly adopted by companies of all sizes, small, medium, and large. And many companies have realized the revolutionary potential of this technology and are trying to apply it in their daily activities.

Understanding Blockchain

Blockchain technology is becoming the latest trend and has created a lot of buzz in the tech industry. Many startups and entrepreneurs have started their businesses based on blockchain development services. Blockchain has become the talk of the town today. Blockchain technology has created a lot of buzz in many industries such as banking, finance, healthcare, supply chain management, and more. This technology has also proven its great potential in the creation of digital currency. Thus, this technology brought us Bitcoin and Ethereum. Now it is popular all over the world.

It is a distributed, decentralized, ever-growing ledger with a list of records stored in block format. These blocks are connected to the blockchain using cryptography that keeps transactions confidential. A blockchain is a collection of immutable (tamper-proof) records managed by a collection of computers, not a central authority. All data that is provided in this network is known to all participants, and each of them is responsible for their own actions. Blockchain completely defines a democratic system.

After the birth of digital currency, blockchain technology got familiar to most people. The widespread of blockchain technology has eloped to develop many services in blockchain development. Blockchain has not only benefited the digital currency development, but it has also been used in other big sectors like Data analytics, supply chain management, Agriculture, Tourism, and much more. Generally, blockchain has two major types namely public and private blockchain. In this article, let us analyze the major difference between the private and public features along with its features. 

What is a Public Blockchain?

A public blockchain is a permissionless open source network. This type of blockchain can be used by everyone without exception. Anyone can download it to their computer. They can also see the entire history of the blockchain. You can also store information, send money, receive money and even create smart contracts on the blockchain. So anyone can write, join and participate in the blockchain here. Mining is a feature of a public blockchain that helps users receive rewards for their support in the network.

The public blockchain is completely decentralized and no one controls the network. Once the information is fully verified on the blockchain, cyber attacks cannot change or tamper with the information. This helps protect your data and information. It is fully encrypted and stored on most devices along with a copy of the blockchain. The purpose of public blockchains goes beyond cryptocurrencies such as Bitcoin and Ethereum. These two cryptocurrencies are good examples of a public blockchain. This helps many communities share data securely and transparently.

Features of public Blockchain 

Distributed ledger

Full transparency


High security

Open environment

Full user empowerment

What is a private Blockchain?

A private blockchain is just opposite the public blockchain and it is not a permissionless network and provides full control of the owners. That is, this blockchain will restrict the people who can participate and access the blockchain network. Moreover, the participating people need to have permission to write, read or modify the blockchain which helps to keep their data and information confidential. This blockchain has multiple layers of data access. Hence, a private blockchain will give a huge level of security, performance, and privacy.

Features of private Blockchain

Better scalability

Faster transactions with high efficiency

Compliance support

Full privacy


Before looking at the differences between these two types of blockchain. Let's first look at the similarities between them.

Similarities of public and private blockchain

Blockchain technology have evolved over the years, and the terms are often confusing. This is because private and public blockchains have some similarities.

Both blockchains will only act as an append-only ledger where the information can be added but cannot be modified or deleted. Hence, these are known to be immutable records. 

Every node on both of these blockchains has a full copy of the ledger. Both are decentralized and distributed across a peer-to-peer network of computers.

In both cases, the validity of the entry is checked, thus ensuring a significant level of immutability, which helps prevent tampering with the records.

Both blockchains rely on multiple users to verify changes to the distributed ledger, thus allowing a new master copy to be created that is accessible to everyone at any time.

Now let's look at the main differences between public and private blockchains.

Public Blockchain Vs. Private Blockchain

Public Blockchain vs Private Blockchain: Which to Choose?

Currently, security measures for public blockchains are being strengthened. Moreover, their value will increase even more in the future. However, Private blockchain providers will help a user to control and limits access to certain individuals. This is why these two blockchain technologies serve different business scenarios. Public blockchains offer better services to B2C players. While private blockchains are more suitable for B2B scenarios. So ultimately, the adoption of private or public blockchain depends on the organization using it. Therefore, a business must choose a type of blockchain platform.
