Blockchain is an immutable, distributed registry that records transactions and makes assets (tangible and intangible) much easier to access in corporate networks. Virtually anything of value can be registered and traded in the blockchain network, reducing risks and costs for all participants. But what is a blockchain network?
A blockchain network is a technological infrastructure that allows applications to access registry services and smart contracts. Smart contracts are mainly used to create transactions, which are sent to all balancing nodes in the network and immutably recorded in a copy of the register. End users or blockchain network administrators who use client applications are examples of application users. Orders, invoices, payments, production, and more can be tracked through a blockchain network. By sharing a single vision of reality, members can see all the facts of a transaction from start to finish, giving them more confidence and adding efficiency and opportunities. If so, how many blockchain networks will there be?
In many cases, several organizations form a consortium to build a network, and their rights are determined by a set of policies agreed by the consortium when the network is initially set up. Different types of blockchain networks can be public, private, and authorized.
This guide explains all four types of blockchain networks.
Features of Blockchain Technology
Instead of a single authority, the blockchain relies on a decentralized network of users to verify and record transactions. This feature makes blockchain transactions consistent, fast, secure, accessible, and resistant to counterfeiting. These features are described below.
- Fast: Transactions are sent directly from sender to recipient, no intermediaries are required.
- Stable: The blockchain network operates 24/7 worldwide. Inexpensive: blockchain networks have lower operating costs because there is no centralized leasing intermediary.
- Security: The blockchain’s decentralized node network provides collective protection against attacks and disruptions. Resistant to manipulation: data is transparent and cannot be changed once the registry is marked by time, preventing blockchain fraud and other criminal activities. Similarly, anyone with access to the public blockchain network can view the transactions made.
Types of Blockchain Network
Blockchain networks can be built in a variety of ways. They can be built by a group of people called public, private, authorized or consortium
Public Blockchain Network
A public blockchain is where anyone in the world can see and send transactions, and if they are valid, those transactions are recorded and can participate in the consensus process to decide which blocks are added to the chain and which are in their current state. to be.
Cryptoeconomics, a combination of cryptographic verification and economic incentives using procedures such as proof of work (Bitcoin) or proof of stake (Ethereum), secures the public blockchain (Ethereum). These blockchains are generally considered “completely decentralized”.
A public blockchain provides a mechanism to protect application users from developers, making it clear that certain actions are not accessible even with the permission of the application developer. Because public blockchains are public, they can be adopted by many organizations without third-party verification.
The anonymity of public blockchains is another reason why it attracts many followers. Yes, it is a safe, secure, and open platform to do business well and efficiently. In addition, you do not have to provide your identity or name to participate. No one can track your online activity as long as your identity is protected.
However, it requires a lot of computing power, has little or no confidentiality for transactions, and has no security. An important consideration for blockchain use cases in these industries.
Private Blockchain Network
A private blockchain, also known as a managed blockchain, is an authorized blockchain, managed by a single entity. The central authority of a private blockchain decides who can be a node. Also, a central authority does not always grant the same privileges to each node to perform its functions. However, it is only partially decentralized, as public access to private blockchains is limited. Ripple (XRP), a virtual enterprise exchange network and Hyperledger, a comprehensive project for open source blockchain applications, are two examples of private blockchain.
For data confidentiality, corporate network sharing often requires a high level of confidentiality. If you need this, a private blockchain is the best bet. Private blockchains are certainly a permanent network alternative, as only a few users have access to certain transactions. Consistency is also very important in any industry. Any technology that does not comply with strict compliance rules will fail at some point. To make transactions easy and straightforward, the private blockchain maintains all the rules of compliance and integrates them into the ecosystem.
Both private and public blockchains have their disadvantages. Public blockchains take longer to validate new data than private blockchains, and private blockchains are more vulnerable to fraud and malicious parties. In addition, a centralized approach often encourages over-reliance on third-party management tools and benefits many industry players. To overcome these shortcomings, a blockchain consortium was created.
Industries that Benefit from Various Blockchain Networks
Blockchain technology is effective in several industries, such as supply chain, finance, real estate, and gambling. By using smart contracts, which are automatically executed codes stored and accessible on an immutable blockchain, companies and individuals can avoid the cost and ambiguity of interacting with third parties to conduct sustainable business. Bitcoin (BTC), Bitcoin Cash (BCH), Litecoin (LTC), and other payment-oriented cryptocurrencies demonstrate the use of blockchain technology. Traditional third-party payment providers are in many respects less efficient than blockchains and are globally accessible. In addition, energy companies such as gas and electricity suppliers and utilities can benefit from the blockchain in several ways. One such application is the smart grid, which requires a local market for energy supply and demand. Another blockchain application is the secure sharing of data between smart meters in the house.
In addition, industries that rely on efficient and secure data ownership and management mechanisms, such as healthcare and digital ID, are primarily looking for new advanced solutions supported by blockchain network protocols. Blockchain allows users to send data anonymously and securely, using public key cryptography, which provides a public key for receiving transactions and a private key for sending transactions.
For governments and institutions around the world, the blockchain can be a powerful tool for securing transactions, streamlining operations, and increasing public confidence. For example, governments can use blockchain to protect sensitive information, such as date of birth, social security number, address, and driver’s license number. Another potential benefit of the blockchain for governments is cost savings and reduced inefficiency. Blockchain technology eliminates redundancy, simplifies procedures, and ensures data integrity.
Concerns Surrounding Blockchain Technology
Despite its various advantages, a blockchain without a stable ecosystem of network participants or a validated consensus process is vulnerable to attacks and centralized control. Decentralization and flow, the amount of data that a blockchain can process at any one time, are important factors to consider. The blockchain trilemma – balancing and maximizing scalability, decentralization, and security in a single network is receiving a lot of attention.
Another problem with blockchain is the environment. For example, consensus schemes for proof of work (PoW) often consume a lot of energy to function. Other concerns relate to the technological complexity and threats that blockchain technology will bring to businesses and individuals. The rapid growth of cryptocurrencies in the global financial scene was just the beginning of the integration of blockchain technology in business and everyday life. Many industries are experimenting with blockchain technology, and many are learning about the benefits and benefits that blockchain-based products and services can bring to their daily lives. Unfortunately, the blockchain business shows no signs of slowing down, and the technology has great potential to become part of, or even completely replace, the digital architecture of the world in the future.
