A public blockchain allows anyone to join freely, while a private blockchain allows only selected and verified participants on the blockchain in this article, we’ll be looking at these two types of blockchain
Blockchains are the decentralized ledger technologies that underpin cryptocurrencies like Bitcoin and Ethereum.
The combination of these cryptocurrencies and the blockchain technology that underpins them makes it possible to transfer value over the internet without needing a third party to act as an intermediary, such as a bank or credit card company. This is made possible by the decentralized nature of the blockchain.
Most cryptocurrencies cannot function without the immutable public ledger known as the blockchain, which contains a list of all transactions.
This is because it enables people who are not familiar with one another to make secure payments to one another without the need to go through a third-party validator such as a bank.
Transactions that are performed using traditional debit or credit cards have the potential to be less secure than those that are made utilizing blockchain technology. This is because blockchain networks are, by their very nature, encrypted.
Blockchain Explained
What is Blockchain?
In late 2008, an anonymous author or authors using the moniker Satoshi Nakamoto released a whitepaper outlining the ideas behind a new form of the digital currency they termed Bitcoin. Each new coin built on these principles is an improvement.
Nakamoto's purpose in creating Bitcoin was to eliminate the need for a trusted third party (such as a bank, a credit card company, or a payment processor like PayPal) in online transactions between strangers.
Because of this, a method was needed to prevent “double spending,” which is the practice of spending money twice without making a new purchase. A network designed to monitor Bitcoin transactions in real time is the answer. The blockchain is that system.
Bitcoin transactions are recorded and validated by a distributed network of computers that cannot be controlled by any single entity, even a government. The “blockchain” refers to the distributed ledger that stores all this data.
A blockchain is a distributed digital ledger of all the transactions that have occurred on the network of computers that make up the blockchain. Because of this, the blockchain is very safe to use.
Several transactions in each block of the chain are recorded whenever a new transaction takes place on the blockchain, and a copy of the transaction is added to the ledgers of all nodes in the network.
Distributed ledger technology is a decentralized database managed by a network of individuals rather than a single entity (DLT).
Advantages of Blockchain
- Global access
- Privacy protection
- Ease of accessibility
Global access
Blockchain technology makes it possible to send cryptocurrency transactions worldwide speedily and inexpensively.
Privacy protection
Payments made using blockchain-based cryptocurrencies do not require users to provide their personal information. This eliminates the risk of compromised users' personal information or stolen identities.
Ease of accessibility
Transactions on cryptocurrency networks is transparent because they are recorded in a distributed ledger called the blockchain. That rules out any opportunity for monetary or transactional manipulation and any mid-game rule changes. In addition, these currencies are based on open-source software that anybody may access and examine.
Disadvantages
- Limited Scalability
- Storage issues
- Data immutability
- Limited Scalability: Unlike their centralized competitors, blockchains have limited scalability. If you've ever transacted on the Bitcoin network, you know that transaction times fluctuate based on how busy the network is. As additional users or nodes join the network, the probability of a decrease in speed increases.
- Storage issues: A storage issue arises due to the fact that blockchain databases must be kept indefinitely by all nodes in the network. As the number of transactions increases, so does the size of the database, which exceeds the capacity of a single personal computer.
- Data immutability: The inability to alter information stored in a blockchain is a major drawback of the technology. It's good for the economy and the logistics network. If the network's nodes are evenly dispersed, then immutability can exist. If a single organization controls more than 50 percent of a blockchain network's nodes, the network is at risk.
Types of Blockchain
There are three types of blockchains, and they are;
- Public blockchain
- Private blockchain
- Permissions blockchain
In this article, we'll focus on public and private blockchains.
Public Blockchain
A blockchain is considered public if it allows anyone to join and participate in the fundamental operations of the blockchain network without any restrictions. On a public blockchain network, anybody may read, publish, and audit the ongoing actions, which helps create the self-governed and decentralized nature typically emphasized when blockchain is addressed.
A public blockchain is decentralized, meaning no one entity controls the network. This means that anyone can use it. In addition, once data on a public blockchain has been authenticated, it is not feasible for the data to be modified or altered. This makes the data on such a blockchain extremely safe.
Characteristics of Public Blockchain
- Safe and secure
- Accessible
- Anonymity
- Absence of regulations
- Transparent
- User-controlled
- Fixed
- Decentralized
- Safe and Secure: It is safe to use public blockchains. As a result of Mining (the 51% rule).
- Accessible: The public blockchain is open and accessible to all users
- Anonymity: Everyone using a public blockchain can remain anonymous. Because there is no requirement for you to use your valid name or identity, everything would remain secret, and no one would be able to find you down based on that.
- Absence of regulations: The nodes on a public blockchain are not required to comply with any rules. Therefore, there is no end to how one might utilize this platform for their benefit.
- Transparent: The nodes that make up a public blockchain are not compelled in any way, shape, or form to conform to any set of regulations. Because of this, there is no limit to the number of ways an individual can use this platform to their advantage.
- User-controlled: Users on virtually any network are expected to abide by many rules and protocols. In many situations, the practices may not even be fair to follow. However, this does not apply to public blockchain networks. Because there is no centralized authority to monitor the actions of the users at this location, everyone who uses it is given complete control over their actions.
- Fixed: Once the information has been added to a public blockchain, that information cannot be altered in any way.
- Decentralized: The public blockchain is decentralized; hence there is no third-party involvement
Private Blockchain
A private blockchain is referred to as an entire blockchain because its users are required to obtain permission from the network administrator before joining the network.
A network administrator manages a private blockchain. Because one or more businesses control the network, users are forced to rely on third parties to complete financial transactions.
In this kind of blockchain, only the entities that took part in the transaction are privy to the information regarding how it was carried out, and no one else will be able to have access to that information; hence, transactions are kept secret.
Characteristics of a Private Blockchain
- Absolute Confidentiality
- Highly Centralized
- Fast and Reliable transactions
- Improved Scalability
- Absolute Confidentiality: It gives priority to issues relating to privacy.
- Highly Centralized: Private blockchains have a higher degree of centralization.
- Fast and Reliable transactions: When you spread the nodes locally and have significantly fewer nodes participating in the ledger, the performance is much faster. This results in both higher efficiency and faster transaction times.
- Improved Scalability: Having the capacity to add nodes and services on demand can be a significant benefit to the organization.
Conclusion
For both public and private blockchains, when deciding whether to use a public BSV blockchain or a private blockchain, organizations should consider the use case they have in mind for the blockchain and whether the former features would be more appropriate for their needs.
Researching the distinctions between public and private blockchains can help you make a well-informed choice.
This will guarantee that the blockchain you choose can process the volume of transactions you anticipate and has the scalability you need to avoid future bottlenecks in your business's performance.
