Private blockchains provide a secure platform for sharing patient data among healthcare providers while ensuring compliance with data protection regulations like HIPAA. This facilitates better coordination of care while safeguarding sensitive medical information. A 2022 study by IBM found that 56% of healthcare executives plan to implement a private blockchain solution by 2025 to enhance data security and interoperability. Public blockchains often employ resource-intensive consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS) to validate transactions. Private blockchains, however, can https://www.xcritical.com/ use more efficient consensus algorithms, as they operate within a trusted network of known participants. One of the big advantages of hybrid blockchain is that, because it works within a closed ecosystem, outside hackers can’t mount a 51% attack on the network.
Similarities Between Public vs Private Blockchains
While private blockchain development offers clear benefits, it’s important to consider potential drawbacks. Its centralized control can raise concerns public blockchain vs private blockchain about potential manipulation by the governing entity, as it deviates from the core principle of decentralization that underpins blockchain technology as a whole. In simpler terms, public blockchains are digital ledgers that are completely open and accessible. This makes them a crucial part of the public VS private blockchain discussion.

In recent years, blockchain technology has revolutionized various industries, with private blockchain emerging as a popular solution for secure and transparent data management. As enterprises explore blockchain applications, understanding the differences between private and public blockchains becomes crucial. This article delves into the key distinctions, use cases, and considerations for choosing between private blockchain and public blockchain solutions.
Private Blockchain vs. Public Blockchains: Key Differences and Use Cases
While some of the top cryptocurrency exchanges are, indeed, based in the United States (i.e. KuCoin or Kraken), there are other very well-known industry leaders that are located all over the world. For example, Binance is based in Tokyo, Japan, while Bittrex is located in Liechtenstein. While there are many reasons for why an exchange would prefer to be based in one location over another, most of them boil down to business intricacies, and usually have no effect on the user of the platform. In layman’s terms, a cryptocurrency exchange is a place where you meet and exchange cryptocurrencies with another person. The exchange platform (i.e. Binance) acts as a middleman – it connects you (your offer or request) with that other person (the seller or the buyer). With a brokerage, however, there is no “other person” – you come and exchange your crypto coins or fiat money with the platform in question, without the interference of any third party.
Disadvantages of Public Blockchains
This transparency builds trust among participants, as everyone can see what’s happening. It also minimizes the risk of fraud since any shady activity would be out in the open for all to see.

Decentralized finance, or DeFi, is an emerging sector leveraging public blockchain technology to recreate traditional financial services in a decentralized manner. DeFi platforms offer a wide range of financial services, including lending, borrowing, trading, and asset management, without the need for intermediaries like banks or brokers. For example, platforms like Uniswap and Compound operate on the Ethereum blockchain, allowing users to trade tokens and earn interest on deposited assets without relying on centralized exchanges or financial institutions. Transparency is a core feature of public blockchains, where every transaction is recorded on a public ledger that is accessible to all participants. This transparency enhances trust among users, as they can independently verify transactions and track the flow of funds. For instance, anyone can inspect Bitcoin’s blockchain to verify the validity of transactions and the total supply of coins in circulation.
A permissioned blockchain is a public or private blockchain where multiple users are given permissions, roles, and abilities. Some designers have solved it using a competitive and distributed validation/block proposing/reward system, while others have solved it using a collateralized system. Private blockchains that limit user access, and manage user privileges centrally, offer better privacy. This should be of limited concern to most users, since blockchain already offers massively improved security and privacy. But these transaction fees reflect the higher costs of operating these high-redundancy, high-node-count blockchains.
- Because it’s decentralized, public blockchains are called “permissionless” and also “trustless” with its anonymous users.
- We’ve got blockchain guides, Web3 ebooks, and complete tutorials on all things blockchain and Web3.
- First and foremost, private blockchains are centralized, meaning that an organization manages them.
- Public blockchains are open to anyone with an internet connection, allowing for inclusivity and participation from individuals and organizations worldwide.
- This should be of limited concern to most users, since blockchain already offers massively improved security and privacy.
- As you may now know, blockchain technology is a highly complex and profound field which consists of numerous concepts and different types of blockchains.
This reduces the computational burden and allows for faster transaction processing compared to public blockchains. With this permissioned structure, private blockchains give businesses more control over who sees their sensitive data and who can participate in specific transactions on the network. Fewer participants also means private blockchains can validate transactions much faster.
Private blockchains, such as Quorum and Corda, excel in controlled environments. With permissioned access and limited validators, they often offer faster transaction processing than public blockchains, but at the cost of transparency and decentralization. The disadvantages of permissioned blockchains mirror those of public and private blockchains, depending on how they are configured. One key disadvantage is that because permissioned blockchains require internet connections, they are vulnerable to hacking. By design, some might use immutability techniques such as cryptographic security measures and validation through consensus mechanisms.
However, you might still be curious about how they are applied in real life. Let’s see public and private blockchains’ practical applications in this section. Quorum, another notable private blockchain, was developed by JPMorgan Chase and offers both high performance and robust privacy features.
51% attacks–Occur whenever a threat actor gains more than half of the blockchain’s hash rate and performs a complete takeover. In this situation, perpetrators can alter transactions, prevent validation, and even reverse completed transactions to trigger double-spending. Due to their size, public blockchains are incredibly difficult, if not impossible, to hack. To attack a public blockchain, threat actors must get past the network’s size, bypass every node, and circumvent cryptographic protocols. In other words, a blockchain is a massive, shared database that stores data in the form of blocks.
This would significantly streamline the data verification process, enabling cheap and fast transactions. More importantly, blockchain holds amazing potential for authenticating transitions without the need of a central authority. Public blockchains are permissionless in nature, allow anyone to join, and are completely decentralized. Public blockchains allow all nodes of the blockchain to have equal rights to access the blockchain, create new blocks of data, and validate blocks of data. Conversely, permissioned blockchains restrict access to the network to certain nodes and may also restrict the rights of those nodes on that network. The identities of the users of a permissioned blockchain are known to the other users of that permissioned blockchain.
Every individual using the respective blockchain can see every single transaction that ever takes place. Both private and public blockchains are “append-only”, meaning that the network can only have information or data added to it, and participants in the network can not alter it. Furthermore, this particular feature of the blockchain technically means that the blockchain is immutable. The only rare case that can change this occurs if a hacker gains a majority of the network’s “hash power” (51%).
