Blockchain Technology 101: A Complete Guide
Published at February 22, 2023

The development of blockchain technology has completely changed how businesses run. Building an app is becoming more and more common as companies look to benefit from this ground-breaking technology.

Blockchain technology is an innovative idea with the potential to uplift many industries. It is a blockchain system that enables data to be managed and stored securely without needing a hierarchy of authority.

It can be found in many industries, including banking, healthcare, legal advice, and government processes. Since blockchain technology is decentralised, it has many benefits, including increased security and transparency.

Although blockchain has long been a significant technology, 2023 will be a turning point for businesses that promise to develop brand-new, unique experiences, according to a report from Globant’s latest Tech Trends. Enterprises are seeking fresh approaches to reach consumers who want experiences that merge the virtual and physical worlds.

As the Web3 ecosystem progresses past the “JPEG” phase of NFTs, defined by low-utility digital art projects, it is anticipated that in 2023, the use of non-fungible tokens (NFTs) will become more complex, personalised, and commercial. The name “NFT” won't always imply digital art, instead, it will be used in a wider range of applications. Hence blockchain enables online cryptocurrency trading between buyers and sellers.

Further, to know more about blockchain, so here is the definition of blockchain technology, its security, how blockchain works, and the types of blockchains below.

What is blockchain technology?

One article from McKinsey showed that blockchain is a technology that securely shares information. A ledger, an accounting journal, is used to keep track of transactions.

The ability to update a blockchain is shared among the nodes, or participants, of a public or private computer network, which is one of today's top technological developments.

A blockchain is a distributed database or ledger. Distributed ledger technology (DLT), is often known as DLT. Blockchain updates are encouraged by providing nodes with digital tokens or currency.

Further, here are three central attributes of blockchain:

  • Cryptographically secure: Two cryptographic keys are required to access or contribute data to the database. First cryptographically is a public key, which is essentially the database address, and a private key, which is a unique key that the network must verify.
  • Since a blockchain is a digital transaction log or database, all transactions occur entirely online.
  • A database that is shared over a public or private network is called a blockchain. The Bitcoin blockchain is one of the most well-known public blockchain networks.

How does blockchain work?

According to IBM, here is the explanation of how blockchain work:

1. A block of data

Each transaction results in the creation of a “block” of data. They prove the movement of an asset, which may be material (a product) or intangible (intellectual).

Your choice of information can be recorded in the data block, including who, what, when, where, how much, and even the condition, such as the temperature of a food shipment.

2. Each block is connected

Each block connects with the ones that came before and after it, forming a chain of information as an asset is moved around or ownership changes.

The blocks confirm the correct timing and prevent any blocks from being changed or inserted between two existing blocks by linking firmly together the order of transactions.

3. Transactions are blocked together

A blockchain is an irreversible chain of transactions that are blocked together. Every new block reinforces the previous block's verification, and by extension, the blockchain as a whole. By doing this, you and other network users may create a trusted ledger of transactions and cut the chance of tampering by malicious actors.

Types of blockchain technology

According to Geeksforgeeks, there is four blockchain technology below:

1. Public Blockchain

These blockchains are open to implementing the decentralisation concept. Anyone with a computer and internet access can join the network, there are no limitations.

Because its name is public, this blockchain is accessible to all users, and no one controls it. Everyone can access this open blockchain. We can also carry out transactions or record verification in this open blockchain. Ethereum and Bitcoin are examples of public blockchains.

2. Private Blockchain

The private blockchain is safer than the public one because only a few nodes can participate in the transaction.

Further, the private blockchain has characteristics such as not being as transparent as a public blockchain, only a select group of approved users can access it, and a closed network is used to run these blockchains.

3. Hybrid Blockchain

It is a hybrid of a private and public blockchain, where some parts are under the authority of a specific organisation and other parts are accessible to the public.

It has characteristics such as combining both private and public blockchains, there are permission-based and permissionless systems, smart contracts enabling the user access to data, and the transactions cannot be changed even if a primary entity owns a hybrid blockchain.

4. Consortium Blockchain

A consortium blockchain is an original strategy that meets the organisation's needs. The blockchain validates transactions, including sending or receiving transactions.

It has characteristics such as a consortium also known as a federal blockchain, it is innovative for the organisation’s needs, it also has a public and private system, and the blockchain is managed by multiple organisations.

How secure is blockchain?

According to McKinsey, a group of determined hackers may attack the blockchain's algorithm by seizing control of more than half of the network's nodes. The hackers can reach an agreement with this simple majority, giving them the authority to confirm fraudulent transactions.

That's exactly what hackers accomplished in 2022 when they stole over $600 million from the blockchain gaming site Ronin Network. It will be necessary to address this problem in addition to the ones related to scalability and standards. Until now, blockchain still has a lot of potential for business and society.

Wrapping Up

The way data is stored and exchanged could be changed entirely by blockchain technology. In several industries, this may make it possible for transactions to be more secure, faster, and less expensive, which would be advantageous to both businesses and customers. However, even though blockchain technology has issues with security, it is predicted it will be popular in the future.
