Blockchain Technology

You must have heard the term Blockchain technology many times, but do you know what blockchain is and its usage? In today’s time, everything has become online, starting from buying clothes to ordering groceries to booking tickets and whatnot. There is a high risk of scams and tracing your important information with all these transactions online. There are various reasons for the popularity of blockchain technology, and one of the significant ones is that it creates trust between different organisations.

As a result, these companies will be willing to do business dealings involving transactions or data sharing that they might not have done otherwise.

What is Blockchain Technology?

Here is blockchain technology explained in detail for you. It is a distributed database intercommunication among the nodes of a computer network. Blockchain, as a database, saves all the data electronically in digital form. It is a shared and unchangeable ledger that enables recording trades in a business network.

Blockchain has become an inevitable part of businesses today because every business runs on information, and this technology helps deliver that information faster. The best thing is that it can be accessed only by permitted network members.

How does Blockchain Work?

Blockchain is defined as digital information to be stored and distributed in a database but cannot be altered. Therefore, it comprises immutable ledgers or records of transactions that cannot be tampered with, erased or destroyed. This is the reason why it is referred to as distributed ledger technology.

Here is the explanation of the transaction process-

• A new transaction is documented
• This transaction is then sent across various networks of peer-to-peer computers worldwide.
• All these networks together decrypt the equation to review the transaction’s validity.
• As they guarantee their validity, they are clustered together in blocks.
• These blocks are chained to build a history of all the permanent transactions.
• After this, the process is completed.

Therefore, you need to remember that it is recorded as a block of data in the blockchain as every transaction happens. Every block is connected to the block before and after it, they link securely so that no block can be tampered with or a new block being inserted between two existing blocks.

Key Elements of Blockchain Technology

By now, you know what a blockchain is? Now, let us understand the key elements involved in the blockchain technology.

Distributed Ledger Technology- Every network participant has access to the distributed ledgers and records of transactions, but they cannot make changes to them. They are immutable ledgers where the users can record transactions just once, and the best part is that it averts the chance of duplication.

Immutable Records- The most notable thing about blockchain technology is that no participant can alter the transaction once recorded on the shared ledger. If there is an error in the transaction record, in that case, it is important to add a new transaction to reverse the error. Once this is done, you will be able to see both the transactions on the ledger.

Smart Contracts- If you wish to have in-depth knowledge of blockchain, you cannot miss an understanding of smart contracts. To increase the speed of transactions, a set of rules is saved on the blockchain and is executed automatically.

Is Blockchain Secure?

Security and trust are made possible by blockchain technology in a number of ways. To start, new blocks are always chronologically and linearly stored. In other words, they are constantly added to the blockchain’s “end.” It is very difficult to go back and change the contents of a block once it has been added to the blockchain unless a majority of the network has agreed to do so. This is due to the fact that each block has its own hash, as well as the hash of the block that came before it and the aforementioned date. A mathematical function that converts digital information into a string of numbers and letters produces hash codes. The hash code also changes if that data is altered in any way.

Data structures created by blockchain technology include built-in security features. It is founded on cryptographic, decentralised, and consensus concepts that guarantee the integrity of transactions.

Benefits of Blockchains

Here are some of the key benefits of blockchain technology:

• Accuracy of the Chain: A network of thousands of computers approves transactions on the blockchain network. By virtually eliminating human involvement from the verification process, less human error and an accurate record of the information are produced.
• Reduced Costs: Consumers typically pay a bank to confirm a transaction, a notary to sign a document, or a preacher to officiate a wedding. Third-party verification is no longer required, and with it, its accompanying costs.
• Efficient Transactions: The settlement of transactions made through a centralised authority may take many days. For instance, if you try to deposit a check on Friday night, you could not actually see any money in your account until Monday morning.
• Decentralization: None of the data on a blockchain is kept in a single location. The blockchain is instead duplicated and dispersed among a network of computers.
• Privacy: Many blockchain networks function as open databases, making the network’s transaction history available to anybody with an Internet connection.
• Transparency: The majority of blockchains use only open-source code. Its code can therefore be viewed by anybody and everyone. This enables auditors to assess the security of cryptocurrencies like Bitcoin.

How Many Blockchains Are There?

There are 4 major types of blockchain:

• Public Blockchain: This blockchain is accessible to all users because its name is public, which implies it is not controlled by anyone. Anybody with access to the internet and a computer with decent hardware can take part in this open blockchain.
• Private Blockchain: Compared to a public blockchain, these are less transparent. Only certain authorised users have access to them. These blockchains run on a private network.
• Hybrid Blockchain: Both public and private blockchains are combined in it. Users can access information through smart contracts.
• Consortium Blockchain: The transaction is validated by this blockchain, which also sends or receives transactions. In this arrangement, the blockchain is managed by multiple organisations.

What Is a Blockchain Platform?

An established blockchain infrastructure can be extended by users and developers using a blockchain platform. Ethereum is one instance, which contains a built-in coin called ether (ETH). However, the Ethereum blockchain also enables the development of programmable tokens for initial coin offers (ICOs), smart contracts, and non-fungible tokens (NFTs). All of them are constructed around the Ethereum network’s infrastructure and are protected by nodes.

Pros and Cons of Blockchain

Pros

Blockchain Applications

After understanding blockchain meaning, it is time to look at its applications. Here are some of the key applications of blockchain technology:

Cryptocurrency

Cryptocurrencies like Bitcoin are built on the blockchain. Blockchain enables Bitcoin and other cryptocurrencies to function decentralised by dispersing their activities across a network of computers. In addition to lowering risk, this also does away with numerous processing and transaction expenses. Moreover, it can provide people in nations with weak financial systems or currencies with a more stable currency that has a wider range of uses and a larger network of contacts with whom they can do business both locally and abroad.

Cybersecurity

Data structures created by blockchain technology include built-in security features. It is founded on cryptographic, decentralised, and consensus concepts that guarantee the integrity of transactions.

Supply chain

End-to-end tracking in the supply chain can be made more transparent and precise thanks to blockchain. The ability to trace assets from production to distribution or end-user use is made feasible by organisations’ ability to digitise physical assets and generate a decentralised immutable record of all transactions.

Conclusion:

This was everything about what is blockchain and how works. It has various benefits because every organisation has started using it, such as individual control of data, visibility & traceability, increased speed, reduced costs and improved security & privacy.

Including it in your system can help gain the clients’ trust, as they have the faith that their confidential data will not be leaked or shared with anyone else. Blockchain is a revolutionary technology that stamps out fraud and helps get transparency.
