Blockchain is a shared immutable ledger used for recording transactions and tracking assets.

It’s a data structure consisting of linked blocks of data.

It operates a decentralized technology that allows the participants of a peer-to-peer network to make transactions without the need for a central authority.

An asset can be tangible (cash, land, or house) or intangible (intellectual property rights, branding it copyrights)

Types of blockchain

We have mainly four types

Public blockchains: this is the first type of blockchain, it removes the problems of centralization so a user which is part of the public can access previous records, and there is full transparency of transaction, the anonymity of this blockchain is why so many people are attracted to it

Private blockchain: private blockchains are not as open as public,

They have only selected nodes as participants which makes it more secure,

The rate of a transaction is very high due to few participants, for data confidentiality, networking at the corporate level frequently necessitates a higher level of privacy.

Hybrid blockchain: this is a mixture of both public and private because some parts are controlled by the organizations while some are made visible as a public blockchain.

Consortium blockchain: this is also known as a federated blockchain

it’s an innovative method to solve company needs, some parts are public, and some parts are private.
