    What is blockchain? 

    A blockchain is a distributed database or ledger among the nodes of a computer network. A  blockchain is a digital record of transactions that is replicated and distributed across a  network of blockchain computing systems. Each block of the chain contains multiple  transactions, and whenever a new transaction occurs on the blockchain, a record of that  transaction is recorded in the ledger of each participant. Distributed ledger technology  refers to decentralised databases managed by a large number of people (DLT). As blockchain  technology evolves and becomes easier to use, it’s your job to understand it and plan for the  future. If you are new to blockchain, this is the best place to start.  

    This means that the change is immediately visible when adjusting the pickup. To crack a  blockchain system, hackers must change every block of the chain in every distributed  version of the chain. Blockchains like Bitcoin and Ethereum continue to expand as blocks are  added, greatly increasing the security of the ledger. 

    What Is a Block? 

    Every chain consists of multiple blocks and each block has three basic elements: 

    • The data in the block. 

    • The nonce — “number used only once.” A nonce in blockchain is a whole number  that’s randomly generated when a block is created, which then generates a block  header hash. 

    • The hash — a hash in blockchain is a number permanently attached to the nonce. For  Bitcoin hashes, these values must start with a huge number of zeroes (i.e., be  extremely small). 

    Types of Block chain 

    Private Blockchain Networks 

    Public blockchains, also known as permission-less blockchains, are completely open  and follow the idea of decentralisation to a T. Bitcoin and Ethereum are both  examples of public blockchains. Anyone on the network can access the chain and add 

    blocks. Public blockchains are also largely anonymous, unlike private blockchains  that do not hide the identities of those involved in transactions. 

    Public Blockchain Networks 

    Bitcoin and other cryptocurrencies originate from public blockchains, which also  played a role in the spread of distributed ledger technology (DLT). Public blockchains  also help overcome some of the challenges and issues, such as security vulnerabilities  and centralization. With DLT, data is distributed over a peer-to-peer network instead  of being stored in one location. 

    Permissioned Block chain Network 

    Permissioned block chains, sometimes referred to as hybrid blockchains, are private  blockchains that allow special access to authorized individuals. Organizations usually  set up this type of blockchain to get the best of both worlds, and it allows for better  structure in determining who participates in the network and in which transactions. 

    Consortium Blockchains 

    A consortium blockchain is halfway between public and private blockchains, as it  includes not only one organization’s block chain, but a cluster of them owned by  different organizations. However, it exists within a controlled group of users, unlike a  publicly distributed ledger. 

    What’s the big deal about blockchain?  

    There have been many attempts to create digital currency in the past, but they have always  failed. The main theme is faith. Bitcoin was designed to solve this problem by using a  specific type of database called blockchain. Most regular databases, such as SQL databases,  have an owner who can modify the entries. Blockchain is different because no one person is  in charge; It is run by the people who use it, so the people holding that money can be sure it’s  worth something. 

    Blockchain technology achieves decentralised security and trust in a number of ways. New  blocks are always stored linearly and chronologically at the beginning. That is, they are  always added at the “end” of the blockchain. Once a block is added to the end of the 

    blockchain, it is very difficult to go back and change the contents of the block unless the  majority of the network agrees. This is because each block contains its own hash along with  the hash of the block before it, as well as the aforementioned timestamp. 

    Advantages of blockchain: 

    Decentralization. This is the main feature of blockchain technology and its strength is that  no other organization needs to act as an intermediary to confirm transactions or transactions,  reducing the time it takes to confirm transactions.  

    network distribution. This point offers several advantages at the same time, because when  this network is distributed, no one owns the network at first, which allows different users to  always have multiple copies of the same data. This feature also makes it robust and fail-safe  because the fact that a node is down does not imply any general failure in the network.  

    Similarly, a distributed network means that there is almost no error, because the  information must be confirmed by many participants in the network. Incorrect or malicious  information becomes almost impossible within the blockchain.  

    Low cost for users. The decentralized nature of blockchain allows for person-to-person  transactions to be verified quickly and securely. Eliminating the need for a middleman  reduces costs for users. 

    Disadvantages of blockchain: 

    Privacy – Data on a public blockchain is encrypted and anonymous, yet it is accessible to all  network nodes. As a result, everyone on the network has legal access to this information.  Transaction data may be used to trace someone’s identify online, much as firms frequently  employ web trackers and cookies. This demonstrates that, unfortunately, the blockchain is  not completely safe.  

    Financial regulatory systems provide a difficulty to blockchain deployment. In the event of  fraud, blockchain applications must build a procedure to identify the perpetrator, which is  rather hard. Other regulatory elements of blockchain technology must to be established in  order for it to be widely used.

    Transparency – Blockchain makes the history of transactions more visible than ever before.  Because it is a distributed ledger, each node in the network has a copy of the documents.  Everyone has easy access to the information on the blockchain ledger. Everyone on the  network may view the modifications and the updated record when the transaction history  updates. As a result, everyone has access to all currency exchange information. 

    The future of blockchains  

    While the Bitcoin system is the most well-known implementation of blockchain technology,  many other cryptocurrencies are based on this new technology. While it remains to be  seen if bitcoin will succeed in replacing other types of traditional payment systems,  blockchain technology deployment is developing quickly, and proponents believe it will  bring about significant changes across sectors. 

    This technology is going to be the game-changer in the days to come. According to a Gartner  report, many new innovative companies will use it and at least one business created using  this advanced technology would be worth $10 billion by 2022. By 2030, it could be used as a  foundational technology for 30 per cent of the global customer base. 

    How Does a Blockchain Work? 

    The goal of block chain is to allow digital information to be recorded and distributed, but not  edited. In this way, a block chain is the foundation for immutable ledgers, or records of  transactions that cannot be altered, deleted, or destroyed. This is why block chains are also  known as a (DLT). 

    Is Blockchain Secure? 

    Block chain technology achieves decentralized security and trust in several ways. To begin  with, new blocks are always stored linearly and chronologically. That is, they are always  added to the “end” of the block chain. After a block has been added to the end of the block  chain, it is extremely difficult to go back and alter the contents of the block unless a majority  of the network has reached a consensus to do so. 

    Why Is Blockchain Important? 

    Block chain is an especially promising and revolutionary technology because it helps reduce  security risks, stamp out fraud and bring transparency in a scalable way.

    Popularized by its association with cryptocurrency and NFTs, block chain technology has  since evolved to become a management solution for all types of global industries. Today, you  can find block chain technology providing transparency for the food supply chain, securing  healthcare data, innovating gaming and overall changing how we handle data and ownership  on a large scale. 


    Block chain isn’t only used for financial transactions. Due to its secure and transparent  nature, the technology is versatile to needs beyond one area of expertise. Industries covering  energy, logistics, education and more are utilizing the benefits of block chain every  day. Block chain’s most well-known use (and maybe most controversial) is in  cryptocurrencies. Cryptocurrencies are digital currencies (or tokens), like Bitcoin, Ethereal or  Lite coin, that can be used to buy goods and services. Just like a digital form of cash, crypto  can be used to buy everything from your lunch to your next home
