Guide to Different Networks of Blockchain Technology

Since the inception of cryptocurrency, the popularity of blockchain technology has reached its limit. Today, blockchain applications go beyond the scope Cryptocurrency. There are many use cases, saving companies money and increasing transparency and security of operations. blockchain technology It has an impact on various sectors In different ways, from how to enforce contracts to making government work more efficient.

Blockchain Technology Explained

Blockchain exploits recording information to make it difficult or impossible to modify, hack or spoof the system. It serves as a digital ledger of transactions distributed over computer networks on the Blockchain.

The chain consists of blocks in which each block contains several transactions. Whenever a new transaction occurs on Blockchain, The computerized transaction history is added to the shared ledger. The technology that powers decentralized databases managed by multiple participants is called

Blockchain and acts as a type of DLT, which records transactions using an immutable cryptographic signature called a Retail.

In building a blockchain model like this, if a block is modified, it is clearly interfering with the system. Any hacker activity must modify all blocks of the chain in all versions of the distributed chain.

In the world of cryptocurrencies, blockchains like Bitcoin and Ethereum are constantly growing and adding to the chain, which sums up the security of the ledger.

Blockchain is a technology model that allows applications to access contracts, smart services, and ledgers. The use of smart contracts essentially initiates transactions, which are further transmitted to each peer node in the network and statically recorded on their copy of the ledger.

Why is Blockchain Technology Successful?

Previously, there were several attempts to create a digital currency that did not affect people’s trust. For example, if you invested x dollars, there is no tangible certainty that the return will be in x dollars without theft or fraud.

Bitcoin He bridged this gap and boosted confidence. Bitcoin is a cryptocurrency that uses a specific database called Blockchain. Popular databases like SQL always have someone involved responsible for manually editing the entries.

It provides a specific roadmap for orders, accounts, payments, production and more, keeping track of everything and usage of the blockchain network. Blockchain allows the user to see the end of all transaction facts with a single view of the truth.

Many blockchain networks

A blockchain network can be built in various ways to validate and record transactions. These networks can be

  • Spread
  • public
  • authorized
  • Alliance

1. Public blockchain network

How it works?

The public blockchain is the first blockchain network in which Bitcoin originated. there public blockchain network It eliminates the problems associated with centralization, such as low security and transparency. It also helped popularize distributed ledger technology (DLT).

DLT does not store information only in one place; Instead of distributing it to Peer to Peer Network. This determines the current status of the Blockchain and which blocks should be added to the chain. These networks are those in which anyone in the world can view and send transactions. These transactions are often expected to be included if they are valid.

The public blockchain network technology is not restricted and anyone can register on the blockchain platform to act as an authorized node.

This network is ideal for organizations based on trust and transparency, such as NGOs, social support groups, etc.


  • Public blockchain technology is completely independent of organizations. For example, if the organization you started is dissolved, public blockchains can still operate with the same power as a computer network.
  • These are highly transparent blockchain networks. Also, it depends a lot on the users who follow the security protocols to meet the security level.


  • Difficult to climb well.
  • Networks slow as more nodes are connected.

2. Private blockchain network

How it works?

there private blockchain It works in a restricted way, like a closed network or one that controls a single entity called the Private Blockchain Network. It operates as a public blockchain network using the same decentralized network and peer-to-peer network. However, it works on a smaller scale. These are often known as licensed blockchains or corporate blockchains because they run on a small private network.

Blockchain technology network is often used for Supply chain management, asset ownership and internal voting.


  • A trusted organization creates levels of authorization, security, and accessibility. Here, the organization controlling the Blockchain can see which nodes can view, add or modify data.
  • Restrict access to information to third parties.
  • These are small, so private block chains can run faster and even process transactions faster than public block chains.


  • Private Blockchain networks are often advertised as non-native blockchain networks, as the primary operating basis of Blockchain is decentralization.
  • It is difficult to obtain trust in private blockchain networks because the central nodes determine what is valid.
  • Since it is a small network, this means less security. In the event of an evil knot, it includes the entire consensus method.

3. Hybrid blockchain network

How it works?

Many organizations have chosen a middle ground where they want to have the best of both worlds – the public and private blockchain. So Hybrid blockchain technology It takes elements from public and private blockchain networks. This hybrid blockchain network provides control over who can access specific data in the Blockchain and what data will be open publicly. Take advantage of institutions to create a private permission-based system alongside a public permission-free system.

To simplify, transactions made on the Hybrid Blockchain are announced but can be verified when needed by smart contracts. Separate private information is stored within the blockchain network, although it can be verified.

This technology network is widely used in the real estate sector. Companies can operate their business privately but can disclose advertisements when needed. Specific financial markets can also use this network.


  • It operates in a closed ecosystem that eliminates the chances of hacker activity.
  • It supports privacy but also enhances third party connections.
  • Scalability often trumps a public blockchain network with cheap and fast transactions.


  • The network is not completely transparent due to the vetted information.
  • It does not provide incentives for users to participate or contribute to the network.

4. Blockchain Consortium

How it works?

The fourth and final blockchain network is called AllianceIt works similarly to the Hybrid Blockchain with both private and public network capabilities. It is a private blockchain network technology with limited access to a particular group in an easier way. It differs in how many members of the organization collaborate in a decentralized network. Therefore, it removes the potential risks associated with an entity controlling the network on a private blockchain.

Consensus actions check the predefined nodes and come up with a validation node that initiates, receives and validates transactions. There is also a membership contract for creating and receiving transactions.

It is extremely secure and this blockchain technology adapts to banking and payment models. Banks can also band together to form a union, deciding which nodes will validate transactions. It works well with supply chains, especially food and pharmaceutical applications. Additionally, it works perfectly for research organizations as well.


  • It is a highly secure blockchain network with greater scalability and efficiency.
  • It also offers access controls such as private and hybrid Blockchain.


  • Consortium blockchain networks show less transparency than public blockchains.
  • Network functionality can be compromised if a member node is compromised.


blockchain technology It is rapidly gaining popularity in all sectors. This innovation brought to the table is something no one has ever seen before.

The blockchain networks The ones discussed above have potential applications for increasing trust and transparency and even creating a seamless transnational registry.

The immediate rise of cryptocurrencies such as Bitcoin and others globally is a springboard for integrating Blockchain technology into business and daily life. Today, a group of companies support the technology and know the benefit and advantages that blockchain technology offers.

The next few years and a promising future lock technology They just highlighted the fact that this technological space is not going to stop any time soon. It could lead to a major shift in the way large companies operate. The use cases of blockchain technology to bring about a significant change in digital architecture are increasing.

While the benefits of Blockchain technology networks are broad, there are growing concerns that they lack a stable environment for network participants or a verified consent process and are vulnerable to hacker attacks.

Another growing problem for the world is how Proof of Work (PoWBlockchain technology affects the sustainable future that the world believes in. Another point like blockchain technology It brings technological complexity and an intimidating factor to companies and individuals.
