Blockchain is a record or logs spread over different nodes commonly used by all endpoints in a computer. Blockchains are well known for their substantial contribution to cryptocurrency systems like Bitcoin by maintaining a secure and transparent log of transactions.
A blockchain serves as a database for storing information electronically. Without the help of external parties, participants can have confidence and reliability using blockchain technology.
Working Process of Blockchain and Overview
Blockchain aims to enable sharing and recording of digital information without editing. A Blockchain is a basis for permanent ledgers or records of activities that are neither modified, removed, or erased. Blockchains are also termed Distributed Ledger Technologies because of this (DLT).
Initially, the idea was put forth as a study in 1991. After its introduction and use in Bitcoin, many cryptocurrencies, decentralized finance programs, and NFTs emerged and proliferated. Look for the transaction process of this technology here.
Bitcoin and Blockchain are different
Many people have the mentality of thinking that Bitcoin and Blockchain are the same things. However, it is not the case; Bitcoin works on the principle of Blockchain.
After the introduction of Bitcoin, Blockchain had its first application use. Bitcoin is simply a virtual currency that is designed to be independent and cannot be controlled by any central body in the world. There are many currencies like Bitcoin available currently. Some of them are Dodge coin, Ethereum, Tether, etc.
This Cryptocurrency uses Blockchain Technology to collectively share the transaction list, which is available to all the users and allows Transparency, Decentralization, and security.
Is Blockchain Technology only used in Cryptocurrencies?
No, Blockchain Technology is not limited only to cryptocurrencies. It has a wide range of applications, and now, with the web upgrading its version to 3.0, its domain may expand rapidly.
This Technology can be used in smart contracts, Non-fungible Tokens, secure payment systems, etc. This technology is for anyone looking for speedy and convenient transactions.
Types Of Blockchain
Blockchain Technology is categorized into different categories according to their needs and uses. They are as follows:
Private Blockchain Network
Private blockchains function well for private corporations and organizations on a connection set for only limited users.
It allows businesses to set network characteristics, availability and permission choices, and other crucial security features. A single authority controls a private blockchain network.
Instead of being kept in one place, data is spread throughout a peer-to-peer network using DLT. A consensus algorithm verifies the legitimacy of information; proof of stake (PoS) and proof of work (PoW) are two popular consensus techniques.
It spread about the Distributed Ledger Technology and minimized the problem of centralization and insecurity.
Permission Blockchain Network
They are also called hybrid blockchains, 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 the network and in what transactions.
It provides the feature of both Private and Public Block Chain Networks.
Consortium Blockchain Network
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.
What is the meaning of the Term ‘Mining’ in Blockchain?
Everyone is familiar with the term mining, as we have heard terms like Gold mining, Diamond Mining. In Blockchain Technology, Mining is not just digging up resources.

Despite being linked to Bitcoin, the phrase is also used to describe other Blockchain technologies. To ensure the security of the entire Blockchain without needing a centralized system, mining includes creating a block transaction hash that is difficult to falsify.
Disadvantages or Limitations
Public and private keys are used in cryptography and blockchain; reportedly, private keys have caused issues. One drawback of blockchains is that users face several difficulties if they misplace their private keys.
Another drawback is the scaling limitations resulting from the cap on transactions per node. As a result, completing many transactions and other chores can take several hours. Another important drawback of blockchain is that information can be hard to add or change once it has been recorded.
