What are the 4 different types of blockchain technology?

Transacting in a safe network is the fundamental use of the blockchain. For this reason, various applications of blockchain and ledger technologies exist. To guard against unwanted access to private information, multichain can be set up. It can only be accessed by authorized entities within the organization and is not accessible to the general public. Which type an organization needs to choose for its job depends on that organization.

We can follow orders and payments from beginning to end by using blockchain.

The benefits of blockchain technology include:

  • Greater data security is provided.
  • increased user trust
  • Reduce the production cost.
  • Boost your speed.
  • Tokenization and invocation.
  • It offers unchangeable recordings.
  • Sensible contracts

Blockchain disadvantages include:

  • the impossibility of data tampering
  • For a huge database, substantial storage is needed.
  • If the owner forgets or misplaces the private key, they are unable to access it again.

Application of blockchain in real life

Here is a list of real-world issues that blockchain can help with:

  • utilizing a safe and error-free voting management system.
  • the management of the supply chain
  • In healthcare administration.
  • real estate undertaking.
  • NFT industry.
  • Avoid using original content and copyright.
  • The system of personal identification
  • to create a permanent data backup.
  • Network of Things

Unrestricted Blockchain

It is sometimes referred to as a trustless or public blockchain because it allows anybody to take part in the blockchain’s process for validating data and transactions. These are employed in networks where a high level of transparency is necessary.


  • Blockchain without permission lacks a central authority.
  • Everything about the platform is open-source.
  • complete openness in the transaction.
  • heavy token use


  • Anyone can join as long as they have access to good hardware and the internet.
  • encourage user or entity trust.
  • As a result of being a larger network, it has a high level of transparency.
  • increased participation through a wider decentralization of access.


  • Inefficient use of energy because of a huge network.
  • lower scalability of performance.
  • less privacy because more things are exposed.

Licensed Blockchain

In a particular blockchain network, only a specific set of groups are permitted to validate transactions or data. These are utilized in networks when there is a need for extreme privacy and security.


  • Transparency based on the organization’s goals is a key characteristic.
  • The absence of anatomy and the constrained user base are other features.
  • There is no central authority in it.
  • created by a private organization.

Blockchain is of 4 types:

  • Public Blockchain.
  • Private Blockchain.
  • Hybrid Blockchain.
  • Consortium Blockchain.

1. Public Blockchain

These blockchains are amenable to implementing the decentralization concept. Anyone with a computer and access to the internet can join the network; there are no limitations.

This blockchain is accessible to all users because its name is public, which implies it is not controlled by anyone.

Anybody with access to the internet and a computer with decent hardware can take part in this open blockchain.

Each computer in the network has a copy of any other nodes or network blocks that are present.

We can also carry out transactions or record verification in this open blockchain.


  • Trustworthy: Algorithms exist to identify any scam. Participants don’t need to be concerned about the network’s other nodes.
  • Secure: This blockchain is big since it’s accessible to everyone. There is a greater distribution of records in a huge size.
  • Anonymous Nature: You do not need to give your name or identity to participate, making it a secure platform for your transaction.
  • Decentralized: Each user has a copy of the ledger; there is no single platform that manages the network.


  • Processing: As a result of its magnitude, the transaction procedure moves at a fairly slow pace. The procedure of verifying each node takes a long time.
  • Energy Use: Producing a proof of work requires a lot of energy. To join the network, quality computer hardware is required.
  • Acceptance: Because there is no centralized authority, governments must deal with the challenge of implementing technology more quickly.

Use Cases: Public blockchains can replace existing financial systems since they are safeguarded by proof of stake or proof of work. The smart contract that made it possible for this blockchain to facilitate decentralization is its more advanced aspect. The public blockchains Bitcoin and Ethereum are examples of this.

2. Private Blockchain

These blockchains are not as decentralized as the public blockchain, which is more secure than the others because only a small number of nodes can participate in the process.

Compared to a public blockchain, these are less transparent.

Only certain authorized users have access to them.

These blockchains run on a private network.

In this, only a select few individuals are permitted to join a network within a business or organization.


  • Speed: Due to the transaction’s tiny size, the rate is high. Each node’s verification takes less time.
  • Scalability: The scalability can be changed. The network’s size can be chosen manually.
  • Privacy: Due to business demands for confidentiality, the level of privacy has increased.
  • Balanced: The transaction is more balanced because only a select few users have access to it, which boosts network efficiency.


  • Security- Because there are fewer nodes of this type, there is a potential that they could be manipulated. These blockchains have higher security risks.
  • Due to its centralization, one of the key drawbacks is the difficulty of establishing trust. This is a tool that businesses can employ for misconduct.
  • Count- Due to the limited number of nodes, the blockchain system as a whole may be in danger if any nodes go down.

Use Cases: This blockchain is a terrific asset to secure information without exposing it to the public eye with adequate security and upkeep. As a result, businesses employ them for asset management, voting, and internal audits. Hyperledger and Corda are two instances of private blockchains.

3. Hybrid Blockchain

It consists of a mixture of private and public blockchain content, where some portions are under the authority of a single company and others are made publicly accessible.

Both public and private blockchains are combined in it.

Systems with and without permissions are employed.

Smart contracts allow users to obtain information

Despite being the owner of a hybrid blockchain, a principal entity cannot change a transaction.


  • Ecosystem: This blockchain’s hybrid nature is its greatest asset. Since 51% of users do not have access to the network, it cannot be hacked.
  • Cost: Transactions are inexpensive because just a few nodes verify them. As not all nodes carry out the verification, there is a reduction in computational cost.
  • Architecture: It offers a great degree of adaptability while upholding integrity, security, and transparency.
  • Operations: It can decide which blockchain users to include and which transactions should be made public.


  • Effectiveness: Not everyone can put a hybrid Blockchain into practice. Additionally, the business has certain issues with maintenance efficiency.
  • Transparency: Someone can keep some information secret from the user. Whether an organization will grant access to someone seeking it through a hybrid blockchain depends on the organization.
  • Ecosystem: This blockchain lacks the incentives for network membership because of its closed ecosystem.

Use Case: It offers a better answer to the government, real estate, finance, and healthcare sectors. It offers a solution for situations in which data must be protected privately but must be accessible to the public. The Ripple network and the XRP cryptocurrency are examples of hybrid blockchains.

4. Consortium Blockchain

It is an original strategy that meets the organization’s needs. The transaction is validated by this blockchain, which also sends or receives transactions.

Federal Blockchain is another name for it.

This approach is novel in how it addresses the organization’s needs.

A portion is both public and private.

In this arrangement, the blockchain is managed by multiple organizations.


  • Speed: Verification is quick because there aren’t many users. Organizations can use this more readily because of the fast speed.
  • Authority: It can be dispersed at every level and involve multiple entities. Decentralized power increases security.
  • Privacy: The checked blocks’ information is hidden from the general public. however, it is accessible to all blockchain participants.
  • Flexible: The flexibility of the blockchain varies widely. The decision can be made more quickly because it is not a big one.


  • Approval: The procedure is less flexible because it has the support of all the members. There may be discrepancies in the vision of interest since one or more entities are participating.
  • Transparency: If the organization turns corrupt, it might be hacked. Information may be kept from users by organizations.
  • Vulnerability: This blockchain is more susceptible if a small number of nodes are compromised.
  • Cases of Use Businesses, banks, and other payment processors have a lot of possibilities for it. The organizations’ food monitoring is a federated solution that is perfect for them to use because they constantly work with their sectors. Tendermint and Multichain are two examples of consortium Blockchains.
