In the 21st century, Blockchain is the most discussed emerging revolutionary technology due to its vast applications in transforming the modern world by revolutionizing different industries like health care, supply chain management etc. Blockchain has modern human thinking about handling data, security and consumer trust. But what exactly a blockchain is and how does it work? Curious to know and Learn?? In this article, we will break down the fundamentals of blockchain in simple words and explore its potential and how it transforms our lives and works.
What is Blockchain?
Term blockchain comes from the way that how this technology works
Blocks: a stack that contains transactional data.
Chain: a series of blocks that are stacked up chronologically.
Basically a chain is a digital ledger that records transactional data in a secure, transparent and temper proof method.
Visualize Block chain as a stack of digital “blocks”and that stack of digital blocks referred to as a Block chain, where each block contains a list of transactional data, once a block is added, it cannot be altered or changed making the system highly secured and reliable.
Blockchain is a decentralized technology, which means not a single person has control over the entire network which makes it more transparent secure and smooth and resistance to fraudulent activities is very high unlike traditional ledgers controlled by central authorities like banks or governments.
How does BlockChain work?
To understand how this technology works, Let’s break it down into a simple step-by-step process.
1. Initiated a transaction
Let’s suppose someone wants to send someone a cryptocurrency or any data, the transaction is initiated.
2. Verification of Transaction
Once a transaction is initiated, it is broadcasted to a networks of computer called nodes. to verify this transaction validity these nodes uses complex algorithms.
3. Added to Block
Once the validity of the transaction is verified the transactional data is stacked with other transactions into a block each block has a unique code called hash which links the particular block to the previous block.
4. Added to a chain
once a block is stacked it is added to the existing blockchain, creating a permanent and unchangeable record.
5. Transaction is completed
Now the transaction is completed and is visible to everyone on the network.
The major security feature of blockchain relies in consensus mechanisms which ensures that all nodes agrees on the validity of this transaction also the whole process is secured by the cryptography technology which ensures that data cannot be tempered or changed.
Blockchain Key Features
Blockchain technology is more superior and reliable than traditional ledgers due to its core and unique features.
1. Decentralize network
The most unique feature of blockchain is its decentralization means not a single identity has the control to operate the network which reduces the fear of corruption and fraud.
2. Transparency
Once a transaction is completed on Blockchain it is visible to everyone on the network which promotes trust and accountability
.
3. Invariability
Once a transaction is recorded on the blockchain it cannot be changed, altered nor get deleted which ensures the integrity of data and privacy of consumers.
4. Security
Blockchain technology uses advanced security features of cryptography and the data is end-to-end encrypted which protects the data from hackers and frauds.
Applications of Blockchain
Blockchain is not only related to cryptocurrency technologies it also offers a wide range of applications in the modernization and revolution of different industries
1. Cryptocurrencies
Blockchain powers digital currencies like bitcoin,Ethereum and litecoinsetc by acting as a decentralised network that ensures the privacy and security of the consumer by providing the seamless experience of peer to peer transactions.
2. Supply chain Management
To ensure transparency and to avoid fraud companies should use block chain technology to track products from origin to consumer which will eventually increase there productivity also increase their profits as well.
3. Healthcare
blockchain also provides vast applications in healthcare industries hospitals should use blockchain technology to track and maintain patients’ records which also ensures data privacy.
4. Voting Systems
Blockchain technology also helps in conducting elections it helps in creating a tamper-proof voting system which improves election integrity.
5. Smart contracts
By using blockchain technologies cryptocurrencies have executed contracts that automate their agreements without intermediaries.
Advantages and Disadvantages of Blockchain
Like any other technology blockchain technologies also have their advantages and drawbacks as well.
Advantages:
Let’s discuss the advantages of blockchain first.
1. Advanced Security
Data stored in the block chain is end-to-end encrypted which makes an extra layer of security which is nearly impossible to hack.
2. Transparency
All transactions in blockchain are transparent and are visible to everyone reducing the risk of fraud.
3. Efficiency
There are no intermediaries involved in the chain, so the process of the transaction is efficient and the cost of the transaction reduces.
Disadvantages:
Like other technologies, blockchain also has some drawbacks let’s discuss them.
1. Scalability
Due to the increased popularity of blockchain among people and adoption of this technology massively this network technology becomes slow as it grows.
2. Energy consumption
Due to the increased adoption of technology, some of the consensus mechanism requires significant energy.
3. Complexity
As this technology is new it can be difficult to understand and implement for layman
Future of Blockchain
Blockchain is an emerging technology and still in its early stages but its potential is unmatchable and enormous and has the power to revolutionize different industries and make a world better place to live in.
Here are some important trends of blockchain to watch:
Decentralized Finance (DeFi)
This is one of the most important trends of blockchain which should nearly be adopted in future it destroys the complexity of traditional ledgers and allows to introduced a financial systems which will be operated without any banks or intermediaries.
Non-Fungible Tokens (Nft’s)
It allows people to invest in unique digital assets like different art, music and different collectables.
Web 3.0
blockchain has the potential to empower the connectivity experience of people by introducing the internet powered by blockchain which is more efficient and faster than conventional internet.
As the Blockchain technology evolves and becomes more familiar to people around the globe it will transforms the industries, empowers individuals, and create more transparent and righteous world.
Blockchain is a revolutionary and emerging technology which enhanced the concept of data handling, sharability and security of data. By adding extra layers of transparency and security blockchain increased the trust factor among individuals in the digital age. Whether someone is interested in cryptocurrencies, smart contracts or the future of the Internet. Understanding the fundamentals of blockchain is the first step toward unlocking its potential.
