How Does Public Blockchain Differ From Private Blockchain?

Public Blockchain Vs Private Blockchain - How To Find A Better Blockchain Platform For Your Business Needs ?

Nowadays, Public and private blockchain has been a topic of discussion ever since the invention of blockchain technology. It is important to understand the significant distinctions between the two. Public and private blockchain are crucial for businesses seeking people to choose their best solution. And a lot of people continue to mix them up. Therefore, this blog will give you clarity to find the right blockchain by knowing their similarities and differences with unique features and choosing anyone that best suits your business needs.

What Is A Public Blockchain?

A blockchain network that anyone can access easily whenever they need is said to be a public blockchain network. It is a permissionless blockchain. Generally, there are no limits to participation. Anyone may view the ledger and participate in the consensus process, which is even more advantageous. 

For example, Ethereum is one of the public blockchain platforms. Thus, if you are in need of a complete decentralized system, then the only choice is the public blockchain. But, it is a bit risky when you try to implement it in the enterprise blockchain function. 

These platforms operate more slowly than usual. Additionally, it may attract bad actors who use the site for illicit purposes because of its anonymous nature. 

What Is A Private Blockchain?

Let us dive into private blockchain before getting into the comparison of public and private blockchain. 
A unique form of blockchain technology is called a private blockchain that allows networks controlled by a central authority. It is a permission blockchain. Truly, any private blockchain solution will include some sort of permission system to identify users accessing the platform. 

Additionally, private blockchain use cases appear to be the ideal solution, since businesses need to maintain their anonymity. If sufficient privacy is not maintained, then their competitors can use the platforms and disclose important material to the media. The long-term effects on brand value are enormous. In some cases, corporate secrecy is essential. 

Let us have a look at similarities and differences with feature aspects of both public and private blockchain.

Similarities Between Public And Private Blockchain 

Here are some of the similarities between public and private blockchain before we go on to the key differences: 


Both public and private blockchains depend on their users and members for the verification or approval of alterations such as the insertion of new or activities to the virtual ledger. 


Whether in their public or private forms, blockchain technologies are all irreversible. In other words, verified data cannot be entirely changed or destroyed by a single person or a large group of individuals. 

Peer-Peer Ledger Replica

To avoid instances of illegal manipulation, public and private blockchains are maintained and disseminated real-time clones of blocks or data throughout every machine on the network.

Key Differences Between A Public And Private Blockchain

There are some key differences to be considered such as, 


Due to the lower volume of transactions that are conducted on a private blockchain, they are lighter and have higher transactional throughput than public blockchain which are heavier due to the enormous volume of transactional activities that are constantly occurring on them. 


Public blockchain are preferred because they provide decentralized power in the hands of all users of the virtual ledger platform, as opposed to private blockchain which is known for centralizing control of the network in the hands of a restricted number of users. 

Accessibility levels

In public blockchain, anyone can access from anywhere in the world and can verify, add, and use data. Private networks differ in that case and only authorized parties can enter the network.


The decentralized architecture and engaged user base work together to increase network security on public blockchain. While, there is a higher danger of hacks, breaches, and internal manipulation due to fewer players managing the network with private blockchain. 

Advantages / Features of Public And Private Blockchain 

Advantages /Features of Public Blockchain

Public blockchain are the original distributed ledger architecture that drove the development of blockchain technology. They can be audited, sent, received, and verified by anyone from anywhere on the globe. Every node or computer that makes up the network must agree to approve a transaction before it can be considered valid on the network.

The most well-known public blockchain include for Litecoin, Ethereum, and Bitcoin. Its features and benefits are, 

Unlike client-server platforms, public blockchain do not have a centralized databases. Each node participates in the validation of fresh transactions and maintains its own master copy of the database on the blockchain network. This aids in getting rid of the unwanted middlemen that are frequently present in centralized transaction chains. 

Public blockchain are difficult to manipulate or launch an attack because it is hard to simultaneously update all of the copies of the database that are stored on each node in the network. 

Another important key advantage of public blockchain is user anonymity. The use of cryptographic identities known as public keys shields user identities from prying eyes. 

Benefits /Features Of A Private Blockchain 

The key components of the private blockchain are access control and permission networks. Typically the admin or founder of the platform will extend an invitation and need validation of new users with respect to standards they have established. Enterprise blockchain are typically used by companies for intra company transactions with limited access to members and staffs. 

Its benefits and features are , 

Private blockchain stand out for their extensive admin control who can and cannot use the system. though the business identity management systems, new users are verified and granted entry to enterprise the data. 

Public blockchain have more nodes while enterprise blockchain have fewer. Due to a lower percentage of users acceptance to establish consensus , processing , and validating transactions or activities become incredibly quick.

The entire virtual platform is under the jurisdiction of a single entity in private blockchain. The platform's day to day administration is guaranteed by the admin according to the rules, procedures , techniques , and tools that are set forth. 


Thus, we have concluded this blog with informative aspects of public and private blockchain. This could give you some idea to choose your platform without any confusion. You have seen their features benefits, key differences and also similarities to get some knowledge about blockchain and usage in different aspects. We, Bitdeal leading Blockchain  Development Company can provide you both blockchain platforms to build your business needs.
