In the most simple sense, blockchain can be understood as a transaction and storage medium, but it is one that is structured in a fundamentally way compared to traditional databases and data storage techniques. While the explanation of exactly how and why is beyond the scope of this article, it’s still worth quickly going over blockchain’s advantages. Anyone can read and write to private blockchain vs public blockchain the blockchain; transactions are publicly visible to all network participants.
Are Private Blockchains Better Than Public Blockchains?
Instead, we use decentralized identifiers (DIDs) to enable users to securely store data on their personal devices and organizations to instantly verify the https://www.xcritical.com/ authenticity of their credentials. Public blockchains can be used to securely transfer funds across borders, reducing the risk of fraud and increasing trust in the financial system. For example, a public blockchain could be used to record and verify the transfer of funds between banks or other financial institutions. This would allow for greater accountability and transparency in the transfer process.

Ethereum miners altered the blockchain following the DAO hack in order to rewrite history so it never happened. Some felt this broke the immutable principle and decided to continue using the old chain, now called Ethereum Classic. Moreover, all the histories of the transactions are kept hidden, away from the public eyes.
Private Blockchain vs. Public Blockchain: What’s the Difference?
To gain access to a private blockchain network, individuals must receive an invitation and verify their identity or provide the necessary information. Access to the underlying biometric data does not necessarily have to be an open affair for everyone. Data can be stored, managed, and protected using private or hybrid blockchains to give restricted access to a defined set of authorities. The issuance of digital identities can be done by the government or a tech firm. Irrespective of the issuing authority, a public blockchain is not ideal, as access to the stored data by the general public can unduly compromise people’s data. Asset management can best be boosted using private enterprise blockchain solutions.
Private Blockchain Uses/Examples
For example, a hospital could use a private blockchain to store patient records securely, ensuring that only authorized medical staff can access the information [2]. Hybrid blockchain solutions such as Unibright and Baseline Protocol make it easy for businesses to transition to modern IT and data management systems without starting from scratch. Unibright Connects (part of the Unibright framework) allow businesses to connect their off-chain systems to the blockchain with ease, including creating standards, so each new client doesn’t have to start at the beginning. For example, the German Ministry of Health is now using a combination of both the private Hyperledger and public Ethereum blockchains for their internal processing and transactions.
Difference between Public and Private blockchain
One of the most well-known public blockchains is Bitcoin, which serves as both a digital currency and the underlying technology that records and verifies transactions. Bitcoin’s decentralized nature and robust security have made it a global phenomenon, enabling peer-to-peer financial transactions without intermediaries. The purpose-built and exclusive nature of private blockchains actually render them more insecure than the public blockchain. Since both the sources of data and their validators are oftentimes within the same industry, all it takes is a bit of friendly collusion to completely rewrite the blockchain at will. Since the public blockchain is validated as quick as possible by numerous independent data centers all around the world, consensus is fast and data tampering is nearly impossible.
Which One is Right for Your Business?
This could enable much safer product creation as it allows for greater oversight over the whole process. A business may want to use a blockchain but it might not want all its data publicly accessible. A public blockchain could breach data protection acts or give away business secrets. The right one depends on whether you need access, governance, security, or big sizes.
The many nodes involved in transaction processes make it difficult to scale up in public blockchains. Should the transactions be increased, the number of nodes that will process them in a private blockchain is defined already, making scaling not an issue to worry about. The difference between a private blockchain and public blockchain technology is very pronounced in many aspects numbering more than one. While both may share similarities in that the data or transactions are stored within blocks and encrypted using cryptographic keys, their core functionalities are markedly different from each other. To date, public blockchains are primarily used for exchanging and mining cryptocurrency. You may have heard of popular public blockchains such as Bitcoin, Ethereum, and Litecoin.
- This level of transparency fosters trust and eliminates the need for a central authority to control the system.
- Although this blockchain is full of features, still it’s not that much suitable for enterprise solutions.
- While private blockchains can easily be adapted to boost business processes making them usable in various industries, there are some unique instances where public blockchains are just the best fit.
- A public blockchain is open to anyone who wants to join, and there’s no need for permission.
- PoS requires participants to hold a stake in the network to validate transactions and uses less energy.
- However, this process can be energy intensive and take a significant amount of time.
- Public chains show a ledger of all transactions and give users the ability to trade, interact, and participate on the blockchain without any permissions needed.
In this blog post, we will delve into the key differences between public and private blockchains, discuss their respective advantages and disadvantages, and explore various use cases for each type of blockchain. Public blockchains are open networks where anyone can join and participate. They offer high security and transparency but can be slower and less scalable.
The potential for DLT could spread to military and governmental solutions, which of course would demand the utmost privacy and security for sensitive data to be stored, or communicated with by any new system implementation. Dock enables organizations and individuals to create and share verified data. Public blockchains are transparent, meaning that anyone can view and trace the history of transactions on the network.
Consortium or federated blockchains operate with a particular group of participants who control the blockchain, rather than a single entity. This group sets the rules, edits or cancels incorrect transactions and solicits cooperation among its members, according to a Blockchain Council report. Hybrid blockchains use both private and public blockchains, rather than being a standalone solution. Other concerns may center on the entity that runs or sponsors the private blockchain. This entity calls the shots, potentially leaving some users on the private blockchain network to wonder if that organization’s needs will be met before theirs, she added.
In China, cryptocurrency has been declared illegal, and even entire exchanges have been banned in the country. Also, China has a firm hold on its stance on cryptocurrency restrictions, and it doesn’t look like China will loosen up its bans any time soon. However, Chinese citizens are still able to find ways to work around the ban by using platforms that China’s firewall can’t catch. To help you easily compare them, take a look at this public VS private blockchain comparison table. Public blockchain’s core functionalities and underlying protocols are generally pre-defined and difficult to modify. While there might be some ongoing development and upgrades to the core protocol, these changes typically require widespread consensus among users and miners on the network.
One advantage of a public blockchain is that the more participants there are in the network, the safer it becomes. The more nodes there are within the network, the more complex it becomes for hackers to gain control. No “update” or “delete” options are available in neither the public blockchain nor the private blockchain. This feature is especially useful because it allows for accuracy, accountability, and transparency.
However, while encrypting data is an important security measure, it is not a foolproof solution. As computing power and technology continue to advance, encryption algorithms can become easier to break, making it possible for hackers to access sensitive data that has been encrypted. This is why Dock never adds Verifiable Credentials or personally identifiable information on the blockchain chain to maximize data security. With Dock, Verifiable Credentials and personally identifiable information is never stored on our public blockchain. The private blockchain vs. public blockchain exposition will best be understood with the analysis of the examples of both. This section will be dedicated to discussing the examples of these unique types of blockchain, and the companies that are utilizing them.
With these fundamentals in mind, let’s now explore the differences between public and private blockchains. Currently, cryptocurrency transactions are the primary use case for most public blockchains. Regulations for these cryptocurrency transactions are evolving every day all over the world. Cryptocurrency regulations are essential in combatting criminal activity, but they can also cause an inconvenience for those who want complete privacy and anonymity. In a private blockchain, the network operator can grant access to who can read, write, and add to the ledger. Plus, the operator can decide on the allocation of nodes across the network.
Some designers have solved it using a competitive and distributed validation/block proposing/reward system, while others have solved it using a collateralized system. By the time any wannabe bad actor could theoretically identify a transaction to target, millions of transactions have already been written to the blockchain, further enhancing security. Public blockchains are open and decentralized networks where anyone can take part.
It ensures the validity and security of transactions and prevents problems like double-spending. On the other hand, private blockchains have fewer participants and handle only a smaller number of transactions. The beauty of a public blockchain is that it’s completely transparent and open.
Another disadvantage is the potentially slow speed of transactions, which can also be a big impediment for the adoption of public blockchains in the business world. Public blockchains are permissionless, decentralized, and censorship-resistant. Private blockchains are not fully decentralized, as there is an organizing party who can choose participants who read and write on the chain. The critical advantage for private blockchains and DLTs is cryptographic verification of identity. The third option is to combine the two and create a hybrid blockchain business solution.
The business could also choose to have the blockchain and supporting systems automate its invoicing, payments, bookkeeping, and tax reporting. If both authorities and the company have an official shared reference of where the records are kept, then not only can they trust each other, but the public can trust them as well by extent. But this “private only” conclusion is actually simply not true, and is what we like to label as one of the most significant and fundamental misconceptions about blockchain. It’s also more secure since only trusted members can participate in the network.
