Differences Between Private Vs Public Blockchain

The Internet has revolutionized our lifestyle. Teaching, learning, shopping, marketing, outing, entertainment and so many things we are doing through online platforms. Indeed, we are rapidly moving towards a virtual world where you can do various things that usually people do by physically going there. By using the most advanced technology, Cosmic Interstellar Public Chain provides you with safe access to your passionate business through the most reliable blockchain products. The purpose of this service is to create an alternative protocol for building decentralized business applications. 

What Is Blockchain?

In simple, blockchain is a digital world where you can develop a distributed database. On this platform, you can put a series of information in a particular format called a block having a timestamp. There is a highly secured connection between these blocks through cryptographic hash functions. 

With the increasing quantity of data, the number of blocks also increases. But here, cryptography provides secure communications between the sender and the intended recipient for their content. This highly established trust offers the traders and consumers to ingress and interact confidentially.

Blockchain has become the most secure virtual place for online businesses. It has great potential to facilitate people in several industries like education, traveling, healthcare, finance, entertainment, and many more. Because of several variations, there are many types of blockchains like Cosmic Interstellar Public Chain but primarily two are common; public and private.

Public Blockchain

A public blockchain is a domain where anyone can join freely and participate in core activities without any restrictions. You need just a computer and an internet connection to be the node or user of this type of network. Generally, people use public blockchains for mining and exchanging cryptocurrency.

Bitcoin, Ethereum, and Litecoin are common examples of public blockchains. As registered users, people have access to the current and past records of transactions. You also have proof of your work and cryptocurrency mining. 

Private Blockchain

You cannot become a part of a private blockchain directly. It is managed and controlled by a network administrator and you need the invitation to join the network. This network works in a completely private mode because outsiders are not able to connect to the network. 

More than one entity is involved in controlling the network. If you need to join the network you will require an invitation and you have to submit your documents for registration. After verification of the document, the network administrator approves your request and gives you the right to participate.

Differences

Here we’ll discuss the major differences between public and private blockchains by comparing their basic features:

Network Access

In a public blockchain, anyone can join the network and read, write, and participate. Actually, it is a non-permission network. Thus it is called a public blockchain.

Whereas, in a private blockchain, nobody could enter directly, until an already member sends you an invitation request. If you accept the invitation you need to submit your necessary documents. Thus it is a permission-based blockchain.

Network Participants

In a public blockchain, the participants are not familiar with each other because anyone can participate. While in a private blockchain, people become members after identity verification thus their identity is noticeable. 

Database Location

A public blockchain is decentralized in which data is stored in distributed networks or computer servers around the world. 

Whereas a private blockchain is more centralized. Here information is stored on nodes that work as building blocks of the whole database system.

Order Of Magnitude

An Order-of-Magnitude Estimate of the Relative Sustainability of the Bitcoin. In a Public blockchain, this order is quite lesser compared to a private one.

Native Token

Every blockchain usually offers its own native cryptocurrency to reward miners when they add new blocks and is also used for financial tractions including service charges. 

In a public blockchain, it is a must whereas in a private blockchain it is not essential.

Transaction Speeds

It is the speed of data transfer from one participant to the other in terms of the transaction. It depends on various factors like block size, block time, internet speed, and service charges.

In a public blockchain, the transaction per second speed is slow whereas, in a private blockchain, the working is fast.

Data Security

As the database in the public blockchain is decentralized and distributed in a higher number of networks or nodes, thus it is almost impossible to hack the database scattered on different computers. 

But in a private blockchain, the database system is centralized and at a higher risk. So the hackers easily induce the database system and make it less secure. 

Energy Consumption 

Being a distributed and decentralized database, a public blockchain consumes a lot of energy compared to a private blockchain because of a centralized database with less number of servers.

Consensus Algorithms

In order to keep all nodes in the network honest it works as a record-keeping mechanism. It provides proof of work, proof of stake, proof of burn, proof of space, etc., in a public blockchain.

Whereas in a private blockchain, you get proof of Elapsed Time (PoET), Raft, Istanbul BFT, etc.

Miners Collision

As the database in the public blockchain is decentralized so no one is capable to know about the validators. This increases the risk of collisions between miners. 

While in a private blockchain, it is hardly a chance for miners because everyone knows each validator and their credentials in the network.

Effects On Costs

In a public blockchain, this potentially disturbs the business models through disintermediation. It lowers the infrastructure cost.

For a private blockchain, it reduces transaction costs by simplifying document handling and compliance mechanisms.

Examples

In a public blockchain, you have Bitcoin, Ethereum, Monero, Zcash, Dash, Litecoin, Stellar, Steemit, etc.

In a private blockchain, you have R3 (Banks), EWF (Energy), B3i (Insurance), and Corda.

The Bottom Line

Having diverse characteristics, blockchain gives you various benefits over normal banking. But depending on your way of working, investing, and manipulating the circumstances, the investment through blockchain can give such profits that you generally can’t expect in a normal situation.

The technology of the Cosmic Interstellar Public Chain is the most advanced. It promises endless interaction with communities through its digital business solutions. You can share your data with other people and grow your business in a digital world completely safe from cybercrime.
