Types of Blockchain TechnologyBlockchain technology is a versatile tool that can be applied to many different purposes, and as such, there are several types of blockchain networks. The most popular types of blockchain networks are public, private, and consortium blockchains.
Public BlockchainsPublic blockchains are open-source networks where anyone can join and participate in the network. These networks are entirely decentralized, which means they don’t rely on any central authority for validation and consensus.
Transactions on these networks are verified by miners who use specialized hardware to solve cryptographic puzzles. Examples of public blockchains include Bitcoin, Ethereum, Litecoin, and Dash.
Private BlockchainsPrivate blockchains are networks that are owned and operated by a single entity or organization. These networks are not open to the public, which means that only authorized members can access them.
Transactions on private blockchains are validated by the owner of the network, and they don’t rely on miners for consensus. Examples of private blockchains include Ripple and Hyperledger Fabric.
Consortium BlockchainsConsortium blockchains are networks that are owned and operated by multiple entities or organizations. These networks are not open to the public, but they are open to a select group of members who have been pre-approved by the network’s governing body. Transactions on consortium blockchains are validated by the members of the network, and they don’t rely on miners for consensus.
Examples of consortium blockchains include R3 Corda and Quorum.

How Does Blockchain Technology Work?Blockchain Technology is an innovative new way of processing digital transactions. Blockchain technology works by creating a digital ledger of transactions that is secure and transparent. This ledger is composed of a series of blocks, which are linked together using cryptography.
Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. This makes it impossible for any user to modify or delete any transaction in the ledger, as doing so would require altering the entire blockchain. When a transaction is made, it is broadcast to the entire network and recorded in the blockchain. All participants in the network will then validate the transaction by verifying its authenticity and accuracy.
If the transaction is valid, it is added to the blockchain and becomes part of an immutable record of all transactions that have ever occurred on the network. The blockchain technology is decentralized, meaning there is no central authority or single point of control. Instead, all participants in the network validate and store the data in a distributed manner, ensuring that no single user or entity has control over the blockchain. This makes it virtually impossible for anyone to alter or delete any data stored on the blockchain. Blockchain technology has already revolutionized many industries, and its potential for new applications is still largely untapped.
It is secure, distributed, and immutable, making it a reliable and efficient solution for many use cases. Companies of all sizes are already taking advantage of blockchain's benefits, and its implementation will only continue to grow in the future. This guide has gone over the basics of what blockchain technology is, how it works, the types of blockchains available, and its various applications. With more companies turning to blockchain technology for their operations, it is sure to become an increasingly important part of modern business.
