Intro

In the past few years the term of cryptocurrency, web3, NFT and blockchain have popular around the net, in this article i will explain what is Blockchain and what are the use cases for it.

Hmmm... so what is Blockchain?

Blockchain is not a program or a tool, its a technology that can maintain records of information that cant be manipulated by other people, so we can define it as a transaction record database that is distributed, validated and maintained around the world by a network of computers. Instead of a single central authority such as a bank, a large community oversees the records in Blockchain, and no individual person has control over these records.

Blockchain is based on decentralized technologies. This functions as a peer-to-peer (P2P) network.

Blockchain can be defined as “A peer-to-peer, decentralized, distributed ledger that records transactions efficiently, and in a verifiable and robust fashion.”

History of Blockchain

In 1991, researcher scientists named Stuart Haber and W. Scott Stornetta introduce Blockchain Technology, However, this Technology became unused when Patent came into existence in 2004. However, in the same year 2004, Cryptographic activist Hal Finney introduced a system for digital cash known as “Reusable Proof of Work”.

4 Main types of Blockchain network

there are 4 types of Blockchain network and the first two are the most common popular around.

• Public Blockchain
• Privet Blockchain
• Hybrid Blockchain
• Consortium Blockchain

Public Blockchain

Public blockchains are permissionless in nature, allow anyone to join, and are completely decentralized. public blockchains are primarily used for exchanging and mining cryptocurrency. You may have heard of popular public blockchains such as Bitcoin, Ethereum, and Litecoin.

Privet Blockchain

Privet Blockchain is deferent then public Blockchain since it run and operated by an entity. for example Hyperledger and XRP.

Hybrid Blockchain

The hybrid blockchain is best defined as the blockchain that attempts to use the best part of both private and public blockchain solutions. In an ideal world, a hybrid blockchain will mean controlled access and freedom at the same time.

The hybrid blockchain architecture is distinguishable from the fact that they are not open to everyone but still offers blockchain features such as integrity, transparency, and security.

Consortium Blockchain

also known as a federated blockchain, is similar to a hybrid blockchain in that it has private and public blockchain features. But it's different in that multiple organizational members collaborate on a decentralized network.
