Over the past few years, blockchain technology has been a significant player in the global economy. Businesses now have more secure data handling options because of blockchain technology. Blockchain will undoubtedly continue to impact business operations in the coming decade.
The impact of blockchain technology is being felt across many industries, and the number and quality of cutting-edge use cases are increasing by leaps. Blockchain technology spending is predicted to exceed $19 billion by 2024, and the global blockchain market will reach $39.7 billion by 2025. Blockchains come in two flavors: public and private. In the business world, each type of Blockchain has a certain function. How do you choose the one that is ideal for your company? We delve deeper into the ideas and assist you in selecting between public and private Blockchains.
What is Blockchain?
For the past ten years, blockchain has been a significant tech development. Everyone seems to be talking about it, but underneath the surface chatter, there's no clear understanding of Blockchain or its workings. Blockchain's basic idea is simple, despite its reputation for being difficult to understand. It has the potential to transform industries from the bottom.
Blockchain technology allows for secure information sharing. A database is where data is stored. A ledger is a transaction-recording account book. A distributed database or ledger is a blockchain. One of today's most well-liked technological trends is this. It indicates that all private or public computer network users (or nodes) share the authority to update the Blockchain. DLT, or distributed ledger technology, is the name for this. Nodes are provided digital tokens or money to update blockchains.
Blockchain enables records and transactions that are transparent, unchangeable, and permanent. This allows you to swap any valuable item, whether it be a physical object or a digital one. There are three essential traits of a blockchain: A blockchain database needs to be safe using cryptography. This means that you will require two cryptographic keys to access the database or add to it. The database address is the public key. The private key is the individual key that the network must verify. A blockchain, a digital log of transactions or databases, is the next step. It's completely online.
The ultimate definition is a blockchain, which is a distributed database that may be shared through a public or private network. One of the most well-known public blockchain networks is the Bitcoin network. Anyone can join the social network or create a Bitcoin account. Private networks may also exist. These blockchains are especially helpful for fintech and banking since they make it possible to identify participants and data accessors. There are also hybrid and consortium blockchains that combine elements of both public and private blockchains.
How does Blockchain Work?
Understanding Blockchain and other DLTs may be possible by taking a deeper dive. Everyone can view and change data on a blockchain. The record is stored alongside other transactions in a "block." A blockchain's transactions are secured using different, immutable hashes. The old ones do not overwrite the new data blocks. Just adding them together enables tracking of any changes. Records cannot be overwritten because all transactions are encrypted. The network can recognize and reject any changes made to the ledger.
These encrypted data blocks are "chained" together and recorded sequentially and indefinitely. This creates a perfect audit trail that gives visibility into previous versions of the Blockchain. Each new data added to the network must be confirmed and verified as legitimate by most nodes. Based on financial incentives or with permission, this is possible. A new block can be added to the chain if consensus has been obtained. Then, all nodes are updated by the blockchain ledger.
The first node that can credibly verify the legality of a transaction is given an economic incentive in a public blockchain network. It is referred to as "mining."
What can Businesses Do to Benefit From Blockchain Technology?
According to research, Blockchain and DLTs can open up new business options. They promote cost-efficient transactions, drive automated and secure contract fulfillment, raise network transparency, and cut risk and compliance costs. Let's take it one step further.

- Lower Compliance Costs and Risk: Banks rely heavily on "know your Customer" (KYC) processes to attract and keep customers. Many of the existing KYC processes need to be updated. They can lead to bank costs of up to $500 million annually. Each customer's KYC may need to be verified once under the new DLT system. This will make it possible to increase productivity, lower costs, increase transparency, and improve customer satisfaction.
- Cost-Efficient Transactions: It can save time and money by digitizing records and issuing them via a universal ledger. As part of a letter of credit transaction, two businesses used Blockchain to trade approximately $100,000 in butter and cheese. Instead of taking ten hours, issuing and approving a letter of credit took less than four.
- Secure and Automated Contract Fulfillment: Smart contracts are instructions that have been coded into tokens on a blockchain and can be self-executed under certain conditions. These contracts can be automated to fulfill them. For instance, one store started documenting all procedures and actions, from vendors to customers, and putting them into smart contracts on a blockchain to improve its supply chain management operations. This made it much easier to track the origin of food, making it safer to consume and reducing the amount of human effort required to find lost products.
What Could Blockchain Look Like in the Future?
Reports predict Blockchain will see two major development horizons in the next five years.
- Blockchain as a Service (BaaS): Growth BaaS, a cloud-based service that creates digital products for DLT or blockchain environments, does not require infrastructure setup. Big Tech companies currently lead this service.
- Interoperability Between Blockchain Networks and Other Systems: Different systems can access, see, and exchange one other's data while retaining integrity thanks to interoperability between blockchain networks and external systems. Cross-network use cases like the Internet of Things employing blockchain architecture depend on scalable consensus methods and standardized hardware.
Increased pressure from regulators and customers and improving supply chain transparency will make these changes partially achievable. In part due to consumers seeking out autonomous, centrally regulated systems due to economic uncertainties. Successful pilot programs from large firms will boost consumer and other organizations' trust.
Many elements might restrict potential growth: For starters, the scalability of many popular programs is constrained. Infrastructure and energy needs are included. For instance, consumers may get anxious about regulatory and governance developments if it is not apparent who would enforce smart contract rules. Cyberattacks should be a concern for potential blockchain users.
What is a Public Blockchain?
As the name implies, a public blockchain is a public platform. This means that anyone can join the public Blockchain. It is a network where participation is unlimited. This was the first type of Blockchain to appear in shared networks. A public blockchain is the best choice if you're looking for a decentralized system.
It can be challenging to integrate public Blockchain into an enterprise blockchain network. However, we have plenty to support it, as shown below. This includes equal rights for all participants and security issues.
Public Blockchain has Many Benefits
These are some of the benefits that public Blockchain offers over private varieties.
Maximum Security
Each platform component of the public Blockchain was created with security in mind. Online hacker assaults frequently threaten shared networks. Because of this, public blockchains make an effort to have the best security measures.
All are Welcome
Openness is one of the most critical assets of a public Blockchain. Anybody can log in to the system regardless of where they are located or what device they use. All you need is an internet connection that is stable and reliable. It is accessible to all without restriction so that you can reap the benefits of blockchain technology in a secure and reliable environment.
Anonymous Nature
The anonymity of the public Blockchain is one of the main reasons it has been so popular. It is an open, secure platform that allows you to make efficient and accurate transactions. However, you don't have to disclose your identity or real name to participate. Your digital identity will be secured so no one can track your activity on the network.
There are No Regulations
The use of network servers is not subject to any restrictions on the public Blockchain. There are no limitations on how this platform can be built. This is fantastic for consumer platforms where the Blockchain is not restricted to internal networking.
Indeed, Everything is Decentralized
True decentralization is one of the main draws for all publicly traded blockchain startups. This is a feature that is often absent in private Blockchains. A single platform does not manage the network. Instead, it is a distributed system in which every user has a copy of the ledger. Maintenance activities can be performed from various nodes, and the log is kept up on a consensus basis.
Absolute Transparency
Full transparency is the best thing about any shared network system. This policy is straightforward. Public blockchain companies will allow anyone to see the ledger if they have it. You, as a user, will have access to the entire catalog. This eliminates discrepancies, gray areas, and any corruption in the network.
Impermanence
The open Blockchain cannot be destroyed. Why does this matter? As a result, a block that has already been created and joined to a chain cannot be altered or removed. No changes can be made to the network. Any user wanting to alter the block must create a separate chain.
The User has Full Power
Users are bound to various rules and protocols in any network chain. A public blockchain is a different situation. Users have complete control over the system and can contribute without being supervised by a central authority.
Public Blockchain has its Disadvantages
Public blockchains have many pros and cons. They aren't suitable for internal use because they aren't regulated. They are, therefore, difficult to use in blockchain projects with strict guidelines. They can also be easily hacked by people who want to use the network for illegal activities.
Examples of Public Blockchain
Let's look at some examples of public blockchains currently available on the market.

Blockchain Bitcoin
The most wide range of well-known technology for utilizing the public Blockchain is probably Bitcoin. Its capabilities were constrained. Only blockchain wallets can be used to transfer money between users. The Bitcoin blockchain has developed to provide swift and secure financial transactions.
Ethereum Network
Another excellent illustration of a blockchain that is open to the public is the Ethereum network. Vitalik Buterin was the founder of Ethereum. He identified the weaknesses in the Bitcoin network and set out to create a solution. The landscape was designed to allow smart contracts to be deployed on a decentralized application blockchain platform. This work on blockchain technology was groundbreaking. Later, it was changed in many ways to produce blockchains more conducive to contracts.
Litecoin
The general population has access to Litecoin. Users can transfer money between accounts using the currency as an online banking system or PayPal. Units of Litecoin are used for all transactions. It is faster than Bitcoin, which takes 600 seconds to process one block.
What is a Private Blockchain?
Private blockchains are primarily used to develop internal networks within a small group of users. A private blockchain's management method is different from its public counterpart's. A central system typically manages it with a network administrator at the network's top. Users must have permission to join this type of Blockchain.
The fundamental concept of Blockchain is this. A central body governs its operations. This would imply that the Blockchain is reliant on external programs. The Blockchain is only accessible to those engaged in transactions and has access to it. Nobody else on the Blockchain can access these private transactions.
Private Blockchain has Many Benefits
Private Blockchain is more accessible but has its own set of valuable features:
High Efficiency And Speed
The public Blockchain allows for participation from all users. However, this reduces their productivity and speed. On the other hand, a private blockchain makes use of all resources, which makes it faster and more efficient.
Absolute Privacy
Network sharing at the enterprise level necessitates higher privacy for data confidentiality reasons. Because of this, a private blockchain might be your best choice.
Organization Empowerment
Private blockchains are frequently used by enterprises, not people, to empower them. Each company or organization that wants to run efficiently needs a solid network. Private blockchains begin smaller since there are initially fewer users. This allows them to manage their ecosystem more efficiently with minimal downtime and maximum uptime.
Stable and Balanced
Because only a few users have access to specific transactions, private blockchains provide a safer network choice. Each user group is assigned a set of nodes, which offer network stability so that users can access it. Because they have fewer nodes than public blockchains, private blockchains operate better and facilitate transactions.
Compliance
In any industry, compliance is essential. Technology that does not adhere to strict standards will eventually be in trouble. Private blockchains follow the same rules and incorporate all necessary compliance measures into their ecosystem to speed up transactions.
Speed
Private blockchains can process more transactions per second since only a select few users have been permitted to participate. This shortens the time it takes to achieve an agreement and speeds it up.
Scalability
With the help of qualified blockchain developers, you may scale your private Blockchain. A central system speeds up decision-making and promotes speedier processes because only a few nodes can operate the network.
Completely Legal Activity
Private blockchains are protected against illegal activity. This is partly due to the fact that only a few people have access to the network and must go through a strict authentication process. It is possible to filter out criminal intrusions into the network. This feature is precious for corporate environments. The likelihood of illegal activity being committed is significantly reduced because only verified users can access the system.
Private Blockchain's Disadvantages
The disadvantage is that the central system tends to rely on the same companies and promotes using third-party management solutions:
Private Blockchain Examples
Let's look at some examples of private Blockchain currently available: Hyperledger, Quorum and R3 Corda.
Hyperledger
Hyperledger software can offer customized blockchain technology financial services. It is focused on trust and accountability between all shareholders. A set of rules governs the Blockchain, and each unit follows a predefined procedure. It encourages permissioned transactions. Users must have the required permissions and verifications to join the network.
There are many frameworks within Hyperledger, including Hyperledger Fabric and Hyperledger Grid. Hyperledger Indy also has Hyperledger Indy and Hyperledger Sawtooth. Hyperledger Caliper and Hyperledger Ursa are available.
R3 Corda
R3 Corda has been a significant player in the blockchain technology industry. It works uniquely: it relies on a "state object," with consensus at the transaction level rather than the entire ledger. Transactions don't have to be approved by all nodes in the network.
Quorum
Quorum is an open-source network that leverages the Ethereum private Blockchain. It is excellent for large enterprises due to its privacy-centric features. Smart contracts enable it to work with individual voting rights. Vote-by-vote processing means that a majority, rather than a unanimous vote, must approve each transaction.

Comparing Public and Private Blockchain
We have now covered the basics of private and public Blockchains. It's time for you to choose which one best suits your needs:
Control
Public and private blockchains function differently in terms of authority. The public Blockchain functions more like a decentralized system without centralized control. Users all possess the same power. The private Blockchain, however, only completely decentralizes power. The network is under the supervision of a single authority.
Who can Have Access
Public and private blockchain access is hugely different. The open-source platforms with fewer constraints are better suited for the public version. Everyone has access to the ledger and can participate in the decision-making process because it is shared. But access to the private Blockchain is constrained. Access to the network is restricted to those who have been given permission.
Transaction Fees
Users' wallets are often empty with public blockchains. The number of users does not affect the allocation of resources. An excess of nodes in a network can significantly slow down network performance. It takes longer to process transactions and thus increases the transaction cost. However, private blockchains have many resources that users can use. This means that increasing the volume of transactions will not result in more expensive processes.
Consensus
For your business, the public Blockchain is the ideal choice to reach a complete consensus. All users equally own the network, its nodes, and its permissions. By joining the network, users can read the ledger and mutually contribute their thoughts. Different is the private Blockchain. It functions differently. Who may join is decided by a central authority.
Transaction Speed
Transaction speed is a crucial consideration in discussions about private versus public blockchains. With the former, only specific nodes can participate in transactions. This guarantees that resources won't run out too quickly while maintaining transaction speeds.
However, public blockchains allow for an unlimited number of nodes. The process may slow down if fewer transactions are being requested. Both networks start off with the same efficiency and speed.
Data Control
There will be differences in data handling capabilities. You can read and write on the public Blockchain. Once an action is recorded and written, it can't be undone or modified. Private blockchains allow only one governing entity to report on the ledger. This is limited to a small number of nodes.
System Efficiency
There are substantial differences in system efficiency between private and public blockchains. Because they have fewer transactions and nodes, personal versions are more stable. The public Blockchain has all nodes available to everyone. This can slow down the network and make it less efficient.
Impermanence
The immutability of the Blockchain reveals its validity and security. Its openness is a strength, even though it may appear less secure than a private blockchain. There is no way to undo the writing on or addition of blocks to a chain. Data manipulation and breaches are less likely. The private Blockchain is only partially unchangeable, though. The central authority may occasionally have the power to add or remove blocks from the chain as needed.
