What is Blockchain?

Blockchain technology has the potential to revolutionise how we conduct business. The technology is adaptable, providing benefits ranging from increased operational efficiency to cost savings. As a result, blockchain applications are numerous and diverse, ranging from financial services and supply chain management to healthcare and identity management.

What are the different types of Blockchain?

Public Blockchain: These blockchains are entirely open to the concept of decentralization. They have no constraints; anyone with a desktop and access to the internet can join the network. A public blockchain is one in which anybody is allowed to join and take part in the blockchain network’s core activities. We can also perform transaction or record verification here on the public blockchain.

Private Blockchain: As these blockchains are not as decentralized as public blockchains, only selected nodes can take part in the process, making them more secure than the others. Few people are permitted to take part in a network within a company/organization in this case.

Hybrid Blockchain: It is a mix of the two private and public blockchain content, with some parts controlled by one organization and others made visible as a public blockchain. There are permission-based and permissionless systems in use. Here smart contracts provide users with information access.

Consortium Blockchain: It is a creative approach to addressing the organization’s needs. This blockchain authenticates transactions as well as initiates and receives them. Federated Blockchain is another name for it. This is a novel approach to meeting the needs of the organization. It is partly public and partly private. The blockchain is managed by more than one organization in this case.

Who is a Blockchain Developer?

A blockchain developer is in charge of developing and optimising blockchain protocols. They are also in charge of developing smart contracts and designing the architecture of a blockchain system. They collaborate with web apps that use blockchain technology. A blockchain developer is someone who works on the advancement of blockchain technology. This role is classified into two major groups, which are as follows:

Core blockchain developers
Blockchain software developers

Blockchain-based Applications
