You will also know topics that are very important for any beginner or pro who is interested in Blockchain and Cryptocurrency Blockchain! A Term that is surfacing on the Internet, Social media, News and grabbing high volume attention globally for more than a decade now. 2020 has been a year for the blockchain industry, New technological use cases, Smart contracts, Defi, and the aggressively growing Interest of millennials. Is Blockchain, Bitcoin, Cryptocurrency on your mind? Are you struggling to understand how Blockchain operates? Are you looking for core information about this ecosystem that will help your investment ideas? You\u2019ve been on the right Page and at the right time. Blockchain & It\u2019s Working Blockchain technology is referred to as \u2018Distributed Ledger Technology\u2019 or \u2018DLT\u2019 is a technology that allows digital information to be distributed but not copied. In this technology, the digital information is transferred in the form of \u2018Blocks\u2019 which is stored in the public database called \u2018Chain\u2019. Blocks in the blockchain are specifically made up of digital information like transaction date, participant details, etc. Each block stores a unique code called \u2018Hash\u2019 which distinguishes each block from one another. How does the blockchain Operate? Consider a spreadsheet that can be easily shared with a network of computers where-in thousands of duplicates can be created. You update any data in your spreadsheet and it gets updated on all the computers within the network. Blockchain works similarly. Whenever a new transaction is requested on the blockchain network, a new block is created with the details of the transaction. This block is given a unique Id called \u2018Hash\u2019. The block is sent to all nodes in the network for the confirmation of the transaction. The nodes validate the transaction and share their Proof-of-Work. Nodes receive a reward for a successful proof-of-work. The transaction is completed by adding the block to the existing chain. Why is Blockchain Untampered and Untraceable? Every block contains three main information: - Data, Previous Hash value, and current Hash value. When a person called A has to transfer $100 to a person B. A block is created with the details of the transaction and a unique hash value. Further, if person B transfers $50 to person C, a new block is created with the previous hash value and the new hash value is calculated and stored. As we can see, every new block carries the Hash value of the previous block. And for this reason, the possibilities of any illegal activities would be nullified. If in any case the transaction is altered, the hash values are not replaced but the new block is created with a new hash value.

There are only 21 Million Bitcoins (21,000,000) ever created, so this is the Maximum supply of bitcoin. Bitcoin transactions are processed using a method called \u201cBitcoin Mining\u201d wherein a global network of computers use complex mathematical algorithms to verify each BTC transactions to execute the blocks and are rewarded for successful mining. Today, We have over 7.1 million active Bitcoin users globally who are able to easily store and exchange it easily in multiple forms over multiple platforms under the ecosystem.

Cryptocurrency mining Cryptocurrency mining is a process of verifying the transactions on the blockchain and adding it to the ledger. This is done by programmed computers(miners) by solving some complex equations. Each transaction initiated on the blockchain must be verified by multiple computers in the mining network to complete the transaction and then add these records to Blockchain ledger called Proof-of-Work ( POW). The mining process is basically new coins in exponential value which is the reward for miners on each successful verification. Bitcoin mining, altcoin mining, or Cryptocurrency mining has been a very popular term since the time of the invention of bitcoin, it involves interesting factors like halving, Pool, Schemes. Follow our detailed guide in Cryptocurrency mining to understand more about mining and how to start your own mining setup What are Smart Contracts and Its Working? You must have certainly heard of Ethereum (ETH) - The world\u2019s 2nd largest cryptocurrency next to bitcoin. Smart Contract is an open source protocol ( software) provided by the Ethereum team and built on Blockchain technology. A smart contract acts as a virtual agreement between 2 parties and can be processed only if the agreement conditions are matched. The Platform allows users to develop their own Cryptocurrency token that can be accessed on Ethereum-Blockchain just like bitcoin. Smart Contracts are not only used to develop decentralized applications and currencies but also used in Financial agreements, insurance agreements and places where records must remain untampered and real-time. Understand more about Smart Contracts to join the upcoming defi and other decentralization projects.
