Public Vs Private Blockchain: How Do They Differ?

A blockchain application can be applied to a wide range of industries, from banking to agriculture. It is a distributed ledger, with transactions being recorded by each participant in the chain.
There are two types of blockchains: public blockchains that are open to all, and private blockchains that are accessible only to those that have been given permission to use them.

What Is Public Blockchain?
The word “public blockchain network” refers to a network of blockchains that is open to everyone at any time. By and large, there are no restrictions on who can participate. Additionally, someone who has access to the ledger would be a part of the consensus process.

If you want a fully open network architecture, the decentralised blockchain is the way to go. However, when attempting to merge a public blockchain platform with an enterprise blockchain operation, complications can arise.

In any case, the public blockchain network was the revolution’s initial implementation of the blockchain technology. Bitcoin is credited with setting the groundwork for blockchain technology in general.

What is Private Blockchain?
Private blockchain technology is a subset of blockchain technology in which the network is operated by a single individual. As a result, the general public is not eligible to participate.

All private blockchain solutions will employ some form of authentication to determine who is signing into the network. Private blockchain applications, in essence, include these platforms for an organization’s internal networking system.
As a consequence, you must have confidence in this platform in order to use it. This network model does not work unless there is mutual trust between the nodes. As a consequence, it is restricted to employees inside a company.

The difference between Public and Private Blockchains
A decentralised blockchain is a distributed network. Through downloading the protocol, everyone can read, write, or communicate with the network.
A distributed and autonomous blockchain is a public blockchain. A chain of transactions is formed by registering and connecting blocks of transactions. Each new block must be timestamped and checked by all nodes prior to being added to the blockchain (computers connected to the network).

Each node is identical to the previous one, and all transactions are public. This prevents data on a decentralised blockchain from being altered before it has been checked.

Bitcoin and Ethereum are the most well-known decentralised cryptocurrency blockchains: they are open-source, smart contract-based blockchains.
A private blockchain is a network that is available only by invitation and is operated by a single entity.

For newcomers to the network, permission to read, write, and inspect the blockchain is required. There may be various levels of access available, and data may be encrypted to maintain business confidentiality.

Private blockchains allow businesses to use distributed ledger technology without disclosing sensitive data.

They do, however, lack a critical feature of blockchains: decentralisation. Private blockchain critics would claim that private blockchains are centralised networks that use distributed ledger technology rather than blockchains.

Private blockchains are faster, more efficient, and less costly than public blockchains, which take an inordinate amount of time and resources to validate transactions.

Wrapping up
There are several distinctions between the two technologies. Both public and private blockchains are suitable for business environments if the functionality required is included.
