What is Blockchain technology?

Blockchain Defined: Blockchain is a shared, unchanging ledger that simplifies the process of recording transactions and tracking assets in a business network. Property can be intangible (house, car, cash, land) or intangible (intellectual property, patent, copyright, branding). Anything of value can be tracked and traded on a blockchain network, which reduces risk and costs for all involved.

In simpler words, the digital ledger is like a Google spreadsheet shared among numerous computers in a network, in which, the transactional records are stored based on actual purchases. The fascinating angle is that anybody can see the data, but they can’t corrupt it.

Blockchains are typically managed by a peer-to-peer network for use as a publicly distributed ledger, where nodes collectively follow protocols to communicate and validate new blocks. Although blockchain records are not unchanging as forks are possible, blockchain can be considered secure by design and exemplify a distributed computing system with high Byzantine fault tolerance.

Key elements of a blockchain

Let us know the key elements of a blockchain as follows

Distributed laser technology

All network participants have access to a distributed ledger and an unalterable record of its transactions. With this shared ledger, transactions are only recorded once, which eliminates the duplication of effort characteristic of a traditional business network.

Immutable records

No participant will be able to modify or tamper with the transaction once it is recorded in the shared ledger. If the transaction record contains an error, a new transaction must be added to reverse the error, and both transactions become visible later.

Smart contracts
To speed up the transaction, a set of rules – called a smart contract – is stored on the blockchain and executed automatically. Smart contracts can define conditions for corporate bond transfers, including travel insurance payment terms and much more.

Why is Blockchain Popular?

Suppose you are transferring money from your bank account to your family or friends. You will be able to log in to online banking and transfer money using another person’s account number. When the transaction is completed, your bank updates the transaction record. That sounds simple enough, right? There is a potential problem that most of us overlook.

These types of transactions can be tampered with very quickly. People who are aware of this fact are often wary of using these types of transactions, hence the evolution of third-party payment applications in recent years. But this weakness is essentially why blockchain technology was created.

Most people assume that blockchain and bitcoin can be used interchangeably, but in reality, they are not. Blockchain is a technology capable of supporting a variety of applications across multiple industries, such as finance, supply chain, manufacturing, etc., but Bitcoin is a currency that relies on blockchain technology to stay secure.

Extremely safe

It uses the digital signature feature to conduct fraud-free transactions, making it impossible for other users to corrupt or alter a person’s data without a specific digital signature.

Decentralized system

Traditionally, you need the approval of regulatory authorities such as the government or the bank for transactions; However, with blockchain, transactions are done with the mutual consent of the users resulting in easier, safer and faster transactions.

Automatic capacity

It is programmable and can automatically generate systematic actions, events, and payments when trigger criteria are met.

Benefits of blockchain

Greater transparency

The most well-known benefit of blockchain is to provide transparency. This element may seem contradictory to the blockchain’s privacy and security possibilities, but the two benefits can work together.

Decentralization

Decentralization is one of the top reasons for the steady increase in Bitcoin popularity. In the case of Bitcoin, miners around the world monitor and maintain the integrity of the Bitcoin blockchain. They validate transactions on the Bitcoin blockchain by performing cryptographic calculations.

Transactions are stored in blocks that are hashed together. To compromise with the Bitcoin network, an attacker would need to own 51% of its global hash power, which is extremely expensive and no longer durable. In this way Bitcoin prevents fraud and double-spending, allowing anyone to become their own bank without the need for intermediaries. The decentralized design of Bitcoin makes it impossible for governments to control or influence external influences. This decentralization enables fast and cheap global transactions, a good collection of value and censorship resistance.

Eliminating intermediaries

When buying or selling items online, there has traditionally been a need for intermediaries. Blockchain, however, introduces the ability to send global peer-to-peer transactions without the need for intermediaries. It allows you to pay even without banks, PayPal or other financial institutions. Large corporations such as Alibaba and Starbucks are exploring these blockchain capabilities, paving the way for the future in which cryptocurrency can be used for a variety of purchases. As more blockchains evolve, as is the case with smart contract libraries, a number of applications without intermediaries become available to users. These applications introduce a global marketplace that allows developers to monetize their work but also streamlines the solution-building process by making smart contracts easily accessible.

Cost reduction for business

Blockchain has the potential to reduce costs for businesses and their processes in virtually any industry. Take, for example, the Internet of Things called IoT. Although blockchain integration for this industry is still considered to be in its infancy, it has already introduced visible improvements in operational costs and efficiency.

More security

Consensus is required on the accuracy of the data from all network members, and all valid transactions are unchanging because they are permanently registered. No one, not even the system administrator, can delete a transaction.

New business models

Blockchain capabilities, especially since they relate to cryptocurrencies, are perfect for experimenting with new business models. It is now possible to encourage and reward people for making good life choices, be it health-related or financial, which will ultimately save them money in the long run. With apps on blockchain and new or existing tokens, you can verify that someone has walked 10,000 steps in a day and reward them for doing so. This is a simple example of a completely new type of business model made possible by blockchain capabilities and tokenization.

Advantages and disadvantages of blockchain

Like all types of technology, blockchain has many advantages and disadvantages that need to be considered.

Advantages

One of the major advantages of blockchain is the level of security it can provide, and this means that blockchain can secure sensitive data from online transactions. For anyone looking for fast and convenient transactions, blockchain technology also offers this. In fact, it only takes a few minutes, while other transaction methods can take several days to complete. There is also no third-party interference from financial institutions or government agencies, which many users see as a benefit.

Disadvantages

Blockchain and cryptography involve the use of public and private keys, and, according to reports, private keys have encountered problems. If a user loses their private key, they face a number of challenges, which makes blockchain a disadvantage. Another disadvantage is the scalability restrictions, as the number of transactions per node is limited. Because of this, multiple transactions and other tasks can take several hours to complete. It can also be difficult to change or add information after recording, which is another significant disadvantage of blockchain.
