What is Blockchains Technology?
Blockchain is a technique for storing data that makes it difficult or impossible for the system to be altered, hacked, or otherwise abused. A blockchain is a type of distributed ledger that distributes and copies transactions among the network of computers involved.
Blockchain technology is a framework for storing public transactional records (sometimes referred to as “blocks”) across multiple databases in a network connected by peer-to-peer nodes. This type of storage is frequently referred to as a “digital ledger.”
Every transaction in this ledger is validated and protected against fraud by the owner’s digital signature, which also serves to authenticate the transaction. As a result, the data in the digital ledger is quite safe.
Types of Blockchain
- Private Blockchain network
- Public Blockchain Network
Private Blockchain Network
On closed networks, private blockchains function well for private corporations and organizations. Private blockchains allow businesses to set network characteristics, accessibility and permission choices, and other crucial security features. A private blockchain network is controlled by a single authority.
Public Blockchain Network
Public blockchains, which were the source of Bitcoin and other cryptocurrencies, also helped spread awareness of distributed ledger technology (DLT). Public blockchains also aid in removing some difficulties and problems, including as centralization and security weaknesses. Instead than being kept in one place, data is spread throughout a peer-to-peer network using DLT. The legitimacy of information is verified by a consensus algorithm; proof of stake (PoS) and proof of work (PoW) are two popular consensus techniques.
Permissioned blockchain networks
Permissioned blockchain networks, sometimes referred to as hybrid blockchains, are private blockchains that grant approved users exclusive access. These kinds of blockchains are frequently set up by businesses in order to achieve the best of both worlds. They provide better structure when determining who can join in the network and in what transactions.

Consortium Blockchains
Similar to permissioned blockchains, consortium blockchains feature both public and private components; however, a single consortium blockchain network will be managed by numerous companies. Though initially more difficult to set up, these blockchains can provide superior security once they are operational. Consortia blockchains are also the best for working with various organizations.
