Blockchain is an unchangeable, distributed ledger that makes recording transactions and managing assets (both tangible and intangible) within corporate networks more accessible. A blockchain network makes virtually any value recordable and tradeable, reducing risk and costs for all involved. What exactly are blockchain networks?
Blockchain networks provide technical infrastructure for applications to access ledgers and smart contracts. Smart contracts are used primarily for initiating transactions, sent out across the network nodes, and stored unalterably on each copy of their respective ledger. App users include end-users using client applications as well as network administrators.
Blockchain networks can track orders, accounts, payments, production, and more. Members can access one version of truth for every transaction from inception until completion, granting you greater confidence and increasing efficiency and opportunities. How many blockchain networks exist?
In most instances, multiple organizations form a consortium to establish blockchain networks, with their permissions being determined by policies set out when configuring it initially. There are three other types of blockchain networks: public, private, and permissioned. This guide will introduce the four primary forms of Blockchain networks and highlight their benefits, drawbacks, and applications.
Blockchain Technology: Key Features
Blockchain uses decentralized networks of users rather than one central authority to validate and record transactions, creating consistent, fast, safe transactions that are also affordable. These are some of its attributes.
Rapid Delivery: All transactions can be sent directly from sender or receiver to recipient without an intermediary.
Consistent: Blockchain networks operate around the clock, 24 hours per day and seven days a week.
Cost-Efficient: Blockchain networks operate more cost-effectively because no middlemen seek to rake in transaction profits.
Secure: Blockchains offer collective protection from attacks and outages through their distributed network of nodes.
Tamper-Proof: Once data has been added to a ledger and timestamped, it cannot be altered, making the blockchain impregnable by fraud or criminal activity. Anyone with access to a public blockchain network can see all transactions.

Blockchain Networks Are Classified Into Different Types
There are many ways to build a blockchain network. They can be private, public, permissioned, or built by a consortium group.
Public Blockchain Network
Public blockchains allow anyone to view it, send transactions, and ensure that they will be included in the chain if valid. They can also shape a consensus system, which determines new blocks added to the chain and its current state.
Cryptoeconomics combines economic incentives with cryptographic verification processes such as Proof-of-Work for Bitcoin or Proof-of Stake for Ethereum to secure public Blockchains (Ethereum). Such blockchains can generally be considered "completely decentralized."
Public blockchains can help protect app users by showing that specific actions fall outside the authority of app developers. As public blockchains are open-source technologies, they will likely be adopted and verified by multiple organizations.
Another factor that contributes to Bitcoin's growing popularity is anonymity. Though Bitcoin offers secure and open platforms where users can conduct business efficiently and safely, revealing your real identity or name to take part can be unnecessary - your anonymity means no one can track your activities on the blockchain network list. Security in blockchain use cases across industries must consider these factors for optimal results.
Private Blockchain Network
Private blockchains, or managed chains, are permissioned and administered by one entity. Within such an environment, a central authority determines which nodes may participate. Each node may not always receive equal rights to perform functions; private blockchains are only partially decentralized, as public access may be limited.
Two prominent examples of private blockchains include Ripple (which facilitates the exchange of virtual currencies between businesses) and Hyperledger (an umbrella project for open-source blockchain applications).
Sharing corporate network data requires a higher degree of privacy for data confidentiality reasons, in which case a private blockchain would provide an ideal solution. A private network provides more stability as only selected users can access transactions.
Compliance is vitally essential across industries. Any technology that doesn't adhere to stringent compliance standards will eventually fail; private blockchains incorporate all relevant compliance regulations into their ecosystem to facilitate seamless transactions and ensure smooth operations.
Public and private blockchains both present challenges. Public chains validate data more slowly than private ones; on the other hand, private chains may be more vulnerable to fraudsters or bad actors; their centralized structure requires too many third-party tools for management and only benefits certain participants in an industry. To combat these shortcomings, consortium blockchains were developed.
Consortium Blockchain Network
Consortium blockchains differ from private blockchains by being managed by multiple organizations rather than just one to increase security and be more decentralized than their private counterparts.
Establishing a consortium can be challenging as it involves working closely together between multiple businesses, which poses logistical difficulties and increases the risk of antitrust violations. Certain supply chain members may lack the technology or infrastructure to adopt blockchain. They may be unable to afford the initial costs associated with digitizing data and connecting multiple supply chains.
R3 Software Development's popular blockchain solutions can be found across industries, from financial services to manufacturing. A consortium blockchain can be managed by one party but must remain free from dominance. If all members agree, this individual may impose rules, change balances, and cancel transactions that have proven themselves invalid. They also perform other duties to foster collaboration among businesses sharing similar goals.
A consortium blockchain provides highly secure privacy because any information in blocks that have been verified remains hidden from public view. Accessible only to those who have joined the consortium, this blockchain requires no transaction fee for accessing it.
Flexibility is another aspect that differentiates consortium blockchains from public blockchains. Public chains may present more challenges concerning validators agreeing and synchronizing; any divergence from that agreement leads to forks in such networks, unlike in consortium networks where any such disagreement could cause forks.
The consortium blockchain can bring many advantages yet also presents some disadvantages. Chief among these drawbacks is being centralized and, therefore, susceptible to malicious players; since participation numbers are limited, it's assumed one participant must be the one at fault. Launching a consortium blockchain can be arduous, requiring all consortium members to approve of its communication protocol among members, and more time is taken to establish public networks between businesses due to less flexibility among large enterprises.
Permissioned Blockchain Network
Businesses that have created a private blockchain will most likely create a permissioned network. Note that public blockchain networks are also permissible. It limits the transactions that can be performed by those who are authorized to participate in the network. Participants must receive an invitation or authorization before they can participate.
Permissioned Blockchain networks are a decentralized platform. This means that data isn't stored in a centralized repository; anyone can access it anywhere and at any time. This ensures that every record has an immutable signature. All information and transactions are cryptographically encrypted, ensuring data security and safety. The network's participants and miners remain anonymous.
Transparency is another advantage of permissioned Blockchain. All data and information are visible to everyone. This benefit, however, has backfired and prompted concerns about data safety in the permissionless Blockchain.
On the permissioned Blockchain, one does not have to prove one's identity. All you need to do to join the network is devote your computing power. Anyone who can determine the nonce value solves the complex mathematical puzzle and joins the system as 4 types of blockchain networks.
The limitations of the permissionless system make it a potentially risky proposition for many businesses. For them, permissionless blockchain is not a good option for selling enterprise solutions. Due to these disadvantages, Ethereum's permissionless blockchain is switching from proof of work to proof-of-stake for its consensus method.
Anonymity can be a positive thing, as it keeps the identities of trading participants hidden. However, anonymity can also cause problems. The permissionless blockchain, for example, makes it difficult to trace the people involved in a trade or a scam. These features are the reason why many people use blockchains for illegal activities.

Benefits Of Blockchain Technology For Various Industries
Blockchain technology has many uses in various sectors, such as supply chain management, finance, real estate, and gambling. Smart contracts allow companies and individuals to avoid the costs and uncertainties associated with third parties when conducting regular business dealings; instead, they create code that executes itself and stores on an unalterable blockchain network.
Several payment-focused cryptocurrencies utilize blockchain technology. Blockchain is more efficient and globally accessible than traditional third-party providers. Blockchain technology can benefit energy industries, including utilities and providers of gas and electricity. It serves as an online marketplace for smart grids to sell power to nearby consumers at competitive prices. Blockchain enables safe data sharing amongst residential intelligent metres at the same time.
Blockchain network protocols are also helping industries such as digital identity and healthcare discover innovative, cutting-edge solutions. Blockchains allow users to remain anonymous while still securely transmitting their data using public key encryption, providing users with public and private keys for data transfers.
Blockchain can be an effective tool for governments and agencies worldwide to secure transactions, streamline operations, and foster citizen trust. Governments could utilize it to protect sensitive data such as social security numbers, birth dates, addresses, and driver's license numbers and reduce costs while improving efficiency with Blockchain's ability to cut redundancies while streamlining processes and guaranteeing data accuracy.
Blockchain Technology: What Are The Concerns?
Decentralization and throughput must be given top priority when creating blockchains since they are susceptible to assaults and central control if they lack a stable and auditable consensus mechanism or a safe ecosystem of network members. Industry experts are quite interested in The Trilemma approach, which aims to increase throughput while balancing scalability and decentralization on a single network.
Environmental concerns associated with blockchain include its environmental footprint. Proof-of-work consensus consumes large quantities of electricity, while its complexity and intimidation pose additional obstacles to adoption.
Blockchain technology has only recently appeared in our everyday lives and businesses, following cryptocurrency's rapid rise on the financial scene. More industries are using it now, and more individuals are seeing its advantages. The blockchain sector is growing rapidly, and it may eventually find its way into digital infrastructure.
