Difference Between Public & Private Blockchain
Blockchain can be defined as a decentralized data ledger that allows for secure data transfer. Blockchain technology allows a restricted number of people to share information.
The information in each block is dependent on and related to the information in previous blocks, producing a time-based chain of transactions. A blockchain ledger’s contents can be shared but not changed. If someone tries to change data, all participants will be notified, and the perpetrator will be identified.
Types Of Blockchain
Every ‘block’ is a database section that stores data in granularity. There are two sorts of blockchain: public and private, and the primary distinction is the level of access granted to users. Let’s have a look at the types of blockchains in a detailed way.

Anyone may join in public blockchains since they are permissionless and completely decentralized. In public blockchains, all blockchain nodes have equal access to the network, and they produce new data blocks and validate data blocks.
Public blockchains are the types of blockchains that is now mostly used for bitcoin trade and mining. Some well-known public blockchains are Bitcoin, Ethereum, and Litecoin. The miners work like modern-day bank tellers, completing transactions and receiving (or “mining”) a fee in exchange.
Private blockchains, also known as managed blockchains, are blockchains administered by a single entity. In this types of blockchains, a node is selected by the central authority itself. Additionally, each cluster does not always have the same authorization to perform functions as the foremost authority.
Because of the reason public access to private blockchains is restricted in a way, they are partially decentralized. Ripple a business-to-business virtual currency exchange network. Hyperledger is an umbrella project for open-source blockchain applications. The above are two instances of private blockchains.

Differences Between The Two Types Of Blockchains
Let’s have a look at the difference between blockchain types on the following basis:
A single organization controls the network in a private blockchain. This indicates that the general public is not invited to attend. As a result, the network is only accessible to a selected few.
In a public blockchain system, on either hand, everybody can engage.
A private blockchain seems more vulnerable to hacking, hazards, and data failure than a public blockchain. It’s easy for corrupt actors to jeopardize the entire network, and as a result, it is less secure.
While a public network is more secure due to decentralization and active involvement, it is nearly impossible to assault the system and seize control of the consensus network due to the many nodes.
3. Transaction Speed
Only authorized parties can access and participate in the transaction process in a private blockchain network. As an outcome, the performance does not change.
On the other hand, a public blockchain allows anyone to see and request a transaction/record. Because so many customers request many transactions, the platform takes a long time to process each, slowing down the network’s speed.

4. Transaction Cost
A low-cost private blockchain platform is available. The pricing does not fluctuate significantly based on the number of requests received; it stays steady, exact, and affordable.
The transaction cost of public blockchain platforms is greater than that of private blockchain platforms. The venue, in actuality, has a large number of nodes, which slows down performance. As a result, costs have risen dramatically.
5. Handling Data
In a private blockchain, just a single organization may view and write a separate ledger. Furthermore, only a small number of users/participants have access to the catalogue and depending on the ledger’s legality, they can even delete a block.
As the name indicates, this blockchain is open to the public, enabling anybody to read and edit the roster. This ledger, however, cannot be amended or edited once it has been finished.
6. Chances Of Collusion
Only a single organization can read and write a separate ledger in a private blockchain. As the name says itself, this blockchain is open to the public, allowing anyone to view and report on the roster. However, once it is complete, this ledger cannot change or edit.
As expressed above, blocks can be erased from the record in specific conditions. Consequently, Private Blockchain is unchanging (to some extent).
We realize that once a block gets on the chain, there is no possibility the block can be corrected or erased. This implies that a public blockchain network is entirely changeless.
A private blockchain is almost always efficient because a few nodes have authorization and access to the ledger. Public blockchain platforms face scalability issues due to the many users accessing the register in real-time, and public blockchain networks, as a result, are less efficient.

As you may be aware, blockchain technology is a vast and complex field that encompasses many concepts and blockchain kinds. It’s crucial to grasp these concepts. Knowing what distinguishes public and private blockchains(different types of blockchain) is necessary and beneficial to take your knowledge to the next level.
Understanding the different types of blockchain networks is as important as knowing what a blockchain is and how it relates to bitcoin. When it comes to which blockchain is superior, a public blockchain appears to be the ideal option because it can use in many applications due to its lack of restricted access.
