Moreover, it maintains trust among the whole community of users as everyone in the network feels incentivized to work towards the improvement of the public network. The first example of such a Blockchain is Bitcoin that enabled everyone to perform transactions. Litcoin, Solana, Avalanche https://www.xcritical.com/ and Ethereum are also examples of public Blockchains..

This usually means that the organization needs to hire somebody familiar with Hyperledger. Cryptocurrency EY recently published a report where they estimated the costs of using Hyperledger to be approximately $150K a year. Private blockchains can be more suitable for businesses that need to comply with regulations such as HIPAA or GDPR. To help you easily compare them, take a look at this public VS private blockchain comparison table. The first miner to crack the code earns the right to add the block to the blockchain, receiving a reward in the process. This competition ensures the security of the network since any attempt to tamper with the blockchain would require immense computational power.
- However, having said all of the above, not all public blockchain projects are fit for enterprises use-cases.

- To fully understand the public VS private blockchain debate, let’s see the pros and cons of private blockchains.
- The choice between public and private blockchains depends on specific use cases and organizational requirements.
Ready to add blockchain solutions to your business or government agency?
The only real public vs private blockchain difference is how easy it is to obtain the analytics on one chain vs. another. Private and permissioned blockchains have smaller networks which would be easier to analyze compared to a public blockchain with a larger number of players you have to identify and analyze.. This Blockchain is a permissionless, non-restrictive, distributed ledger system, which means anyone who is connected to the internet can join a Blockchain network and become a part of it. The basic use of such Blockchain is for exchanging cryptocurrencies and mining.
What Are the 4 Types of Blockchains?
As a type of distributed ledger technology (DLT), blockchain is highly resistant to tampering and hacking. Altering data on the blockchain is nearly impossible due to its decentralized structure and robust cryptographic mechanisms. Even the world’s most powerful supercomputers would struggle to compromise its security. These open-source networks enable the execution of smart contracts, allowing a wide range of applications, including decentralized finance, decentralized exchanges, and crowdfunding.
Introducing Public and Private Blockchains
A private blockchain works in a restrictive environment like a closed network or is under the control of a single entity. While it operates like a public blockchain network in the sense that it uses peer-to-peer connections and decentralization, this type of blockchain is on a much smaller scale. Instead of just anyone being able to join and provide computing power, private blockchains typically are operated on a small network inside a company or organization. Private blockchains operate on permissioned networks, offering businesses a safe haven for managing data and transactions with a high degree of control and privacy. Unlike their public counterparts, they cater to customization and ensure data confidentiality. Businesses define the governance rules and manage access points, ensuring compliance with industry regulations and safeguarding sensitive information.
The major difference between the Blockchains is that the public is highly accessible, whereas private is confined to a particular group of people. Moreover, a private Blockchain is more centralized due to the fact that a single authority maintains the network. IBM, R3 Corda, Hyperledger Fabric, Hyperledger Sawtooth, etc. are the examples of private Blockchains.
Issues like these raise questions on whether private blockchains will remain part of the blockchain landscape in the future. The restricted access, or “trusted” blockchain system, tends to make this more attractive to enterprises who wish to keep some or all of their transaction information private. It’s important for businesses to carefully evaluate factors such as data privacy and security, governance, transaction speed, cost, scalability, and regulatory compliance when selecting a blockchain. Consulting with experts and conducting thorough research can also be beneficial in making an informed decision.
Unlike public blockchains where the identity of people are largely anonymous, the identity of people involved on a private blockchain is known. Only selected users may maintain the shared ledger while the owner can override, edit, or delete entries on the blockchain as they see fit. Because public blockchains have dominantly been used by cryptocurrencies to date, less people are aware of the growing number of use cases for public blockchains. Public blockchains provide a secure, transparent, and decentralized platform for a wide range of applications and industries including healthcare, finance, and government. Hybrid blockchains are blockchains that are controlled by a single organization, but with a level of oversight performed by the public blockchain, which is required to perform certain transaction validations. An example of a hybrid blockchain is IBM Food Trust, which was developed to improve efficiency throughout the whole food supply chain.
Private blockchains offer unique advantages in enterprise settings, from supply chain management to financial services. A private blockchain is a type of blockchain network that is restricted to a specific group of participants or organizations. Unlike public blockchains, where anyone can join and participate in the network, private blockchains have controlled access, and typically, only known and trusted entities are allowed to operate as nodes.
An example of securing data linked to a blockchain is by issuing credentials such as identity documents, school degrees, and driver’s licenses as Verifiable Credentials. However, having said all of the above, not all public blockchain projects are fit for enterprises use-cases. In fact, the vast majority of them are oriented towards decentralised applications (such as defi, web3, etc.), and are not fit for large scale consumer applications. Blockchain has enabled a new wave of technological progress that can disrupt many industries and systems before us. This article will take a look at the core differences between public vs private blockchain and the different use cases that both are suited for. Each type of blockchain meets the specific needs of its users and has its own idiosyncrasies to address during development and testing.
The owner or operator has the right to override, edit, or delete the necessary entries on the blockchain as required or as they see fit to make changes to the programming. Private and permissioned blockchains are generally used by organizations or businesses with specific needs. For example, a company could put their data on a private blockchain to keep the information confidential but add a digital fingerprint of the data on a public blockchain to secure it. If someone suspects that the data may have been manipulated and wants to investigate, they can compare the information on the private blockchain with the public blockchain fingerprint.
Initiatives like blockchain bridges, protocol standards, and cross-chain technologies are paving the way for a more interconnected and efficient blockchain landscape. Private blockchains are particularly attractive for enterprise blockchain solutions, where organizations prioritize data confidentiality and regulatory compliance. Account-based systems within public blockchains enable easy use of traditional graph analysis tools.
The platform supports seamless and secure data exchange across various healthcare services, enhancing patient care through improved data accuracy and availability. Scalability can be an issue, particularly when dealing with large transaction volumes that can lead to slower processing times. Privacy concerns loom large, as all transactions are publicly viewable, potentially hindering the use of this technology for sensitive data. Finally, the evolving regulatory landscape surrounding cryptocurrencies and blockchain technology can create uncertainty for businesses looking to leverage this technology. Choosing the right private vs public blockchain depends on your specific needs.
At its core, blockchain is a decentralized, transparent, and immutable digital ledger, where transactions and data are securely recorded. Unlike centralized systems controlled by a single authority, blockchain operates through a distributed network, ensuring trust and accountability. Scalability, or the ability to handle a growing amount of work or transactions, has been a bottleneck for many blockchain networks.
