7. Cryptocurrency

You must have heard of Bitcoin, right? That’s just one single face of the cryptocurrency market. A decentralized digital currency secured by strong cryptography within a digital ledger is known as blockchain.

Some of the cryptocurrencies that add to the dynamic list are:  Ethereum (ETH), Namecoin (NME), Litecoin (LTC), TRON (TRX), Ripple (XRP), Dogecoin (DOGE), and others. The market continues to evolve, bringing forth exciting possibilities and technologies for users and investors.

Types of Blockchain

1. Private 

Private Blockchains are centralized and governed by a person or organization that determines who has access to the Blockchain development technology, who can be added as a node, and who verifies records. Private Blockchains, unlike public Blockchains, are closed and have access restrictions. Anyone who wishes to participate in a private Blockchain must first obtain permission from the administrator.

Example: B2B virtual currency exchanges like Hyperledger.

2. Public

Blockchains enable a decentralized, open network of multiple computers that anyone can use to request or verify the accuracy of a transaction. It enables users to generate new blocks, access all blocks in the Blockchain, and validate data.

Since they are open and require excellent security, they use concepts such as proof of stake or proof of work. Block miners who validate transactions are financially rewarded. Public Blockchains are basically utilized for cryptocurrency mining and exchange.

Example: Litecoin, Bitcoin, and Ethereum Blockchains.

3. Hybrid

Hybrid Blockchains combine the benefits of both public and private Blockchains. They can be centralized or decentralized, and they enable organizations to create a permission-based private Blockchain in addition to a public Blockchain. As a result, organizations can control data access in the Blockchain and what data is publicly accessible. 

4. Consortium

Instead of a single individual, these permissioned Blockchains are governed by a group of companies or organizations. To increase security, they are more decentralized than a private Blockchain. It allows for restricted access, and the consensus process is determined by the current nodes.

Furthermore, it serves as a validator node, initiating, receiving, and verifying transactions, whereas member nodes may initiate or accept transactions. Users can transfer digital assets from one Blockchain to another with greater efficiency and scalability using this service.

Example: Consortium Blockchains are used in banking and payments , such as Corda and Quorum. 

5. Permission-based

Permissioned Blockchain networks, also known as hybrid Blockchains, are private Blockchains that provide special access to authorized individuals. Businesses typically set up these types of Blockchains to get the best of both worlds, and it enables better structure when determining who can participate in the network and in what transactions.

Example: Popular permission-based Blockchains include R3 Corda, Quorum, and Hyperledger Fabric

6. Sidechains

Sidechains are separate Blockchains that operate in parallel with the main Blockchain, providing additional functionality and scalability. Sidechains enable developers to experiment with new features and applications without compromising the main Blockchain’s integrity. For instance, they can be used to build decentralized applications and implement specific consensus mechanisms. Sidechains can also be used to handle main Blockchain transactions, reducing congestion and increasing scalability.

Example: Side-chains comprises the RootStock or RSK or Liquid Network.

Advantages of Blockchain Technology

1. Cost-efficiency

Blockchain eliminates the need for intermediaries, such as banks or payment processors, which reduces transaction processing costs significantly. Businesses leveraging blockchain, like Bitcoin, can save substantial amounts by bypassing the traditional payment system and its associated fees.
