In this tutorial, we discuss what is Blockchain, the content of the course of Blockchain, what are use cases of Blockchain along with simple demonstration, what are the key topics to be covered in main topics, how it is useful to industries, who want to jump start their career in Blockchain as fresher, Is Blockchain right technology for their career path.
Blockchain, is growing list of records, called blocks, that are linked using cryptography. Each block contains a cryptographic hash of the previous block. In other words, distributed consensus. Blockchain was invented by a person using the name called Satoshi Nakamoto in 2008.
The invention of the Blockchain for bitcoin made it the first digital currency to solve the double-spending problem without the need of trusted authority or central server. Blockchain that are readable by the public are widely used by Cryptocurrencies.
Cryptography, is about constructing and analyzing protocol that is to prevent third parties or public from reading private messages, various aspects in information network security such as, confidentiality, authentication, email compatibility and data integrity. Real strength of Blockchain. Cryptography can be used such as, electronic commerce(e-commerce), chip-based payment cards, computer passwords and military communications.
Bitcoin is permission less Blockchain, it is one of most popular Blockchain. Which is successfully implemented and good amount of material. It is decentralized digital currency without a central bank or single administrator that can be sent from user to user on the peer-to-peer bitcoin network. The permission Blockchain (only limited access) that is, Hyperledger fabric.
In December 2015, Linux foundation had announced the creation of Hyperledger project. The objective of the project is to advance cross-industry collaboration by developing Blockchain and distributed ledger, with a focus on improving the performance and reliability of these systems so that they are capable of supporting global business transactions by major technological, financial and supply chain companies.
Key concepts and Functionalities of Hyperledger fabrics are identity management, privacy and confidentiality, efficient processing, modular design, assets, consensus.
The Blockchain technology are integrated into multiple areas such as, video games, cryptocurrencies use to record multiple transactions, smart contracts, financial services, health care, banking, automobile industries and other uses.
Blockchain can be helpful for many people and more businesses to experience its potential in banking and finance industry.
