A lot of the hype surrounding blockchain technology can feel like an abstract concept that is difficult to understand, but with the proper framework, it doesn’t have to be so hard to grasp. In this guide on how blockchain technology will work in 2022, we’ll help you go from knowing nothing about blockchain to understanding how it works and why it matters.
What is Blockchain?
A blockchain is a digital catalogue of all cryptocurrency transactions. Blockchain technology will continue to grow and expand its usage throughout our lives.
Like any new technology, there are still some bugs to be ironed out. It is anticipated that by 2022, blockchain technology will have advanced to the point that it will be quicker, less expensive, and more efficient than the existing transaction methods we use. Blockchain technology has been projected to play a significant role in how individuals buy, sell & trade goods in their daily lives and business transactions from 2019 onwards.
Who Invented Blockchain?
The answer to this question only reached those curious enough to dig deeper into the history of blockchain. In 2008, Satoshi Nakamoto invented blockchain technology as the underlying structure for Bitcoin. Since then, many industries and organisations have adopted blockchain as a secure way to store data and conduct transactions.
In the future, blockchain will become ubiquitous to stay ahead of the curve. It’s essential to partner with a Blockchain Development Company that can help you take advantage of this technology.
Types of Blockchain
Blockchain technology is constantly evolving, and blockchain development companies develop various types of technologies. Mainly there are four types of blockchains:
1 – Public Blockchain
These blockchains are public, and anyone can join as a participant. The most popular are Bitcoin, other cryptocurrencies, and many others, such as Ethereum (ETH) and NEM (XEM). Public blockchains can be used to record any transaction, including the transfer of bitcoin and the execution of sophisticated smart contracts. Because all participants on a public blockchain network can view all transactions, only authorised participants can make changes and update records.
2 – Private Blockchain
These blockchains are not public, and only authorised users can join. They allow for secure transactions on a private network with access granted to selected participants rather than being open to everyone.
Any transaction within a private blockchain is visible only to those with permission to see it, and there’s no need for other network participants to be aware of it. That’s why many companies build their blockchain-based solutions instead of using a public one.
3 – Consortium Blockchain
These blockchains provide semi-decentralized control where they require more than one node to verify the transactions. Usually, they involve a group of entities who want the benefits of blockchain technology without the cost or responsibility of running nodes themselves.
These entities will jointly operate nodes connected via consensus algorithms, consequently eliminating troubles like double spending, which could be present in a fully decentralised blockchain.
4 – Hybrid Blockchain
Hybrid blockchains are a mix of public and private blockchain solutions that offer certain benefits for both. They have semi-decentralized control but with limited and preselected participants having permission to join. In theory, hybrid blockchains provide companies with all of the advantages of blockchain technology without downsides, but it’s still early days for them.
Is there is any Cryptocurrency on the Blockchain?
You can find various types of cryptocurrency, but Bitcoin is the most well-known. Bitcoin is a decentralised digital currency not subject to government or financial institution control. Yet, Blockchain technology powers Bitcoin and other cryptocurrencies and a distributed database maintain a secure ledger for transactions.
Neither an individual nor an entity can control the currency and that’s why you need to Hire Blockchain Developers to create a wallet to use Bitcoin.
How does Proof of Stake Work?
Blockchain technology involves a ledger that is distributed across a network of computers. Each computer has a copy of the catalogue. Every time transaction is made, it is broadcasted to the network, and each node updates its ledger. For a transaction to be considered valid, most nodes must.
Once you have decided to go with a distributed ledger, there are several options for setting it up. The most usual method is called Proof of Work (PoW). Under PoW, miners verify transactions by solving complex mathematical problems. The miners create hashes from all their transactions dealings a block. Once they decrypt a hash that meets specific requirements, they can earn cryptocurrency as a reward.
Privacy vs Anonymity in Blockchain Technology
It’s essential to understand the difference between privacy and anonymity when discussing blockchain technology. While Bitcoin offers a high degree of anonymity, Ethereum focuses on privacy. However, both platforms have been working to improve their scalability and hire blockchain developers to help them reach their goals.
Now let’s dig into blockchain development. Why are companies hiring blockchain developers? It all comes down to scalability. How do you create a system capable of dealing with millions or billions of users? The answer isn’t to create a new blockchain system. Instead, companies are building on top of existing networks. They’re hiring blockchain developers, and their demand is exploding.
Understanding Mining
Mining is essentially finding solutions to puzzles. The miners verify transactions on a blockchain by adding them to a block that needs to meet specific criteria, like making sure there are no duplicate transactions.
Proof of work and stake are two very different yet equally vital forms of mining. Proof of work (PoW) is currently more popular than Proof of Stake (PoS), and that’s why we’ll explain what both processes entail below.

What is a Proof of Work?
This form of mining relies on solving complex math problems, often called mining. Anyone can do this, but miners must have a powerful computer with specialised hardware or a mining rig to make it worthwhile. Proof of work (PoW) utilises large amounts of computing power to create blocks that are added to a blockchain.
You need Proof of work for a transaction block to be added to a blockchain. While all cryptocurrencies use some form of verification of work, Ethereum uses an approach called Ethash, which was designed specifically for its platform. To add transactions and create new blocks on its blockchain, Ethereum requires miners to use PoW, known as Ethash.
What is a Proof of Stake (PoS)
PoS is a different way of achieving consensus and verifying transactions on a blockchain network. It doesn’t require solving complex math problems like PoW, but it has its challenges. Participants with Proof Of Stake(PoS) mine coins to verify transactions by putting up their money.
Consider it as buying shares in a company. Instead of owning all of a company outright, you’d buy shares that entitle you to dividends from future profits. Using PoS, blockchains can more easily process more significant numbers of transactions per second than they could if they used only PoW.
Smart Contracts & DApps Explained
In simple terms, DApps are ‘decentralised applications run on a blockchain. They are usually open source, and anyone can contribute to their development. Blockchain development companies will create and manage these smart contracts and DApps.
Developers have created Ethereum, a blockchain-based distributed computing platform with built-in smart contract functionality. This helps developers build apps on top of it and deploy their smart contracts to the blockchain.
Ethereum enables developers to write applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. Some well-known examples of DApps include Augur, Golem and DigixDAO.
Security Through Encryption Algorithms
All transactions made utilising blockchain technology are encrypted using algorithms. Due of the difficulty of breaking into the system and altering the data, this offers a high level of security. Additionally, because each block is connected to the one before it, if one block were to be altered, the other blocks would immediately show it.
This data is then stored on thousands of computer systems connected worldwide using blockchain technology. If a hacker tries to access one of these computer systems, they can only change their copy of that block’s information. The rest of the system would still show all other documents as correct and valid. It would be immediately apparent if such tampering occurred.
