What Is Cryptocurrency? Everything You Need to Know


Have you ever imagined a world where money is just in digital form and is not managed by banks or governments?

How would a world without middlemen or agencies, where transactions are decentralized, secure, and transparent look like?

This is what cryptocurrency is all about a world offering digital currencies for diverse utility.

But what exactly is the purpose of cryptocurrencies? How does it function? Is it the future of money or a store of value?

We will go into these issues and solve the puzzles surrounding this revolutionary type of money in this article.

What is a cryptocurrency and how it works

A cryptocurrency is a type of digital currency that uses cryptography, a technique for securing communication and transactions.

It’s used to control the creation, ownership, and security of crypto.

Cryptocurrencies are decentralized, which implies that no single entity, such as a government or financial institution, has power over them.

Cryptocurrencies are created through “mining” or are pre-programmed with a limited supply.

In contrast to traditional currencies like the US dollar or the Euro, which are issued and regulated by central banks.

Since no central bank or body is controlling how cryptocurrencies operate, additional units can only be introduced if certain requirements have been satisfied.

For instance, fresh Bitcoins can only be created when a block is uploaded to the blockchain, then the miner will be rewarded in Bitcoins.

After the 21 millionth Bitcoin has been created, none more will be made.

Cryptocurrency transactions are tracked on a public ledger known as a blockchain.

Blockchain is a decentralized and transparent technology that aids in transaction security and verification.

Trading cryptocurrencies is complicated and uncertain, and there are huge risks involved. Prices are subject to change at any time.

Due to its price volatility, trading crypto is suitable for a few investors.

As a result, investing in cryptocurrencies should be regarded as high risk.

Know the dangers associated with investing before making a decision, and seek financial advice.

Understanding the origins and evolution of cryptocurrencies

Cryptocurrency has its roots in the late 20th century. Here is a brief history of cryptocurrency and Bitcoin:

The Developing Concept – 1980s

The creation of digital currency started in the 1980s when researchers like David Chaum and Stefan Brands presented the idea of creating digital cash that will enable private, anonymous, and secured transactions over the Internet.

Chaum is widely acknowledged for the creation of digital cash, which was the predecessor to cryptocurrencies like Bitcoin.

Early Attempts – 1990

Digital currency creation has been attempted in many ways, including DigiCash, eCash, and CyberCash.

These initial efforts, meanwhile, ran across technical and legislative problems and failed to find widespread support.

The Birth of Bitcoin – 2008

Using the pseudonym Satoshi Nakamoto, an individual or group of individuals produced a white paper in October 2008 titled “Bitcoin: A Peer-to-Peer Electronic Cash System.”

This white paper described the architecture of Bitcoin, a decentralized digital money built on the blockchain, a decentralized ledger.

Bitcoin Operation Begins – 2009

For the first time, the Bitcoin software is made accessible to the general public, and mining, which starts the process of creating new Bitcoins, and recording and validating transactions on the blockchain, starts.

Growth And Valuation – 2010

It was impossible to put a monetary value on the units of the newly developing cryptocurrency because it had never been traded, only mined.

For the first time, someone chose to sell theirs in 2010, exchanging 10,000 Bitcoin for two pizzas.

At today’s Bitcoin pricing, the buyer’s Bitcoins would be worth more than $281,100,000 Million if they had been kept.

As an alternative to conventional fiat currencies, Bitcoin gained acceptance in the 2010s, and a few years later several additional cryptocurrencies were created, known as altcoins.

Such as Litecoin, Ripple, and Ethereum, which gave the cryptocurrency industry new features and capabilities like quicker transaction speeds, enhanced privacy, and smart contract capability.

Crypto Market Boom – 2017

The price of numerous cryptocurrencies rose to an all-time high as the cryptocurrency market saw major growth.

This resulted in increased adoption and investment because it gained extensive media attention and publicity.

Cryptocurrency continues to grow rapidly as acceptance among mainstream investors and institutional investors announce their support for cryptocurrency.

Some countries even went to create their digital currencies, known as Central bank digital currencies (CBDCs).

How are Cryptocurrencies Created

Creating a coin requires expertise, patience, and the drive to develop something that others will want to use and own.

There are various ways/methods you can use in creating your Cryptocurrency which include;

  • Developing your native cryptocurrency and blockchain.
  • Create your new crypto on an existing blockchain.
  • Hire a blockchain developer to build a coin for you.
  • Modify the code of an existing blockchain.

The methods above needs an advanced understanding of blockchain technology and how the crypto ecosystem work exactly.

However, in this article, I’ll explore the common method you can use in creating your cryptocurrency.

  • Determine Your Project’s Utilities: this is the first very step every creator or developer must consider before creating. Cryptocurrencies can serve several purposes such as:
  • Means of payment
  • Transfer of Money
  • Smart contract support
  • E-Voting
  • Store of value

It is important to design an attractive use case before introducing your currencies to digital currency marketplaces.

For example, Solana is a cryptocurrency with over 5 different use cases: NFTs marketplace, Decentralized Applications, Decentralized Finance (DeFi), Web 3.0 & Games.

  • Choose A Suitable Blockchain Platform: A blockchain platform serves as the foundation of all cryptocurrencies.

As a result, a system of accountability is established and every transaction is guaranteed to be documented and spread over the blockchain.

With this method, it is difficult for outsiders to hack, deceive, or alter the digital ledger.

Platforms differ based on the consensus method they employ.

A blockchain is fundamentally a type of digital ledger that records each cryptocurrency transaction over time. But not all transactions are taken into account.

Some, for instance, might be fraudulent. Consequently, a screening procedure is needed. In the realm of blockchains, a consensus mechanism offers that.

A consensus mechanism is like a digital voting system that ensures everyone on a network agrees on the same information so that transactions and decisions can be made in a trustworthy and decentralized way.

In layman’s explanation, a consensus mechanism is like a game in that a group of friends plays together to agree on the rules and make decisions so that everyone can play fairly and have fun.

Below are some types of consensus mechanisms:

  • Proof of Stake: Each block is built by a group of miners, with a random miner receiving the reward. Miners must show ownership of a sizable share in the currency they’re extracting.
  • Proof of Work: Proof of work is a technique used by cryptocurrencies to verify the accuracy of new transactions that are added to a blockchain. To make a block, miners must answer challenging arithmetic problems. In exchange for completing the block-building process, miners receive bitcoin.
  • Proof of Authority: a technique called Proof of Authority (PoA) is used with blockchains to transmit transactions relatively quickly through a consensus mechanism based on identity as a stake. Example of the platform using this algorithm
  • Prepare Your Nodes: The nodes that make up the blockchain must be created after you’ve chosen a blockchain. Nodes are often quick computers that join a blockchain network to process and validate transactions.

Nodes record and share data that is eventually added to the digital ledger while maintaining the currency.

Some Factors to consider while setting up a node:

  • Chose an ideal operating system: Ubuntu or Fedora are the most preferred by developers. It enables them to reconfigure the OS to their cryptocurrencies’ unique needs.
  • Determine who access the nodes: Some ledgers are open for the public to access while other are made private.


  • Identifying the location of nodes’ hosting: A node can be hosted by a cloud network, however, local nodes may be preferable to offer on-premise support for PCs that serve as nodes.
  • Selecting the necessary hardware: Because nodes demand faster hardware so that they can execute more transactions in less time, components like processors, RAM, GPUs, and hard drives are crucial factors to take into account.


  • Select A Blockchain Structure: Blockchains don’t all function in the same manner when it comes to sharing data. Similar to conventional architecture, digital architecture must take into account both design and how everything fits together to function as efficiently as possible.

Think about the following three popular blockchain architecture formats:

  • Decentralized: Data are shared among different nodes on the blockchain.
  • Centralized: Information from multiple nodes is sent to one central node on the blockchain.
  • Distributed: A private distributed system allows the users to configure the ledger data while the public distributed ledger lets the users review the content.
  • Establish APIs: An interface connecting to a client network or a blockchain node is known as an application programming interface or API. For instance, an API can act as an interface between a currency exchange and a program that gathers information about that currency.

In the world of cryptocurrencies, APIs can be used for a variety of tasks, but the most frequent ones are currency trading, data security, and currency analysis.

  • Create A Standard UI/UX: Consumers and miners are more likely to be able to simply set up their settings and manage their investments the simpler the UI and UX.

Interfaces need a server and database to function, and someone needs to be prepared to create a website or software that enables data configuration and inspection.

  • Understanding the Legal Requirements: Before creating any crypto you should consider the legal aspect and regulation, & license from the necessary government agencies.

Different Types of Cryptocurrencies

There are thousands of different cryptocurrencies in the world with different functionality. But, they all rely on consensus mechanisms and a blockchain to function properly without the help of a middleman.

Below are the major categories of cryptocurrency:

  • Utility Tokens:

A cryptocurrency on a blockchain with smart contracts known as a utility token performs a specific task inside the ecosystem of a cryptocurrency project.

Utility tokens, unlike cryptocurrencies like Bitcoin (BTC), aren’t intended to be used as a medium of trade in the real world.

Ether’s use case, as an example, is for paying transaction fees to write something to the Ethereum blockchain or building and purchasing Dapps on the platform.

  • Means Of Payment:

A payment cryptocurrency serves as a means of payment as well as peer-to-peer electronic cash to facilitate transactions, as the name suggests.

Examples include Bitcoin, Monero, Dogecoin, Litecoin, and Bitcoin Cash.

  • Governance Token:

Tokens can also be used for governance.  The right to vote on specific issues inside a cryptocurrency network is granted by these tokens to their holders.

These typically involve greater, more important decisions or adjustments and are required to preserve the network’s decentralized nature.

Examples of these tokens include Curve DAO, Uniswap DAO, Aave, & Decentraland.

  • Stablecoins:

This is a type of coin the value is pegged to a reference asset, either money, exchange-traded commodities, or another cryptocurrency. Examples include USDT & BUSD.

  • Non-Fungible Tokens (NFTs):

These are the digital representation of art or real-life asset. They cannot be traded like other cryptographic assets like Bitcoin or Ethereum.

Understanding the advantages of using cryptocurrencies over traditional currencies

Cryptocurrency Traditional Currency
1.)    Borderless Transactions: you can make the transfer to any country using crypto without the need for a middleman. 1.)    Foreign Ex Control: all transactions done here are subjected to foreign exchange control, which can sometimes not approve the transaction.
2.)    Decentralized: no government or central bank can control cryptocurrencies because transactions are carried out on a peer-to-peer network. 2.)    Centralized: Central banks issue and control traditional currencies, which affects monetary policies, exchange rates, and inflation rates.
3.)    Security & Privacy: Cryptocurrencies use advanced blockchain technology to protect information and transactions. This helps in resisting potential fraud. 3.)    Possibility of Fraud: Traditional currencies are vulnerable to fraud and counterfeiting, which might cost people and businesses money. Since transactions can typically be tracked, privacy issues might arise.

Risks and Challenges Associated with Cryptocurrencies

  • Government Does Not Back Cryptocurrency

The value of a cryptocurrency is independent of obligations made by a government or central bank, unlike the majority of traditional currencies like the US dollar.

  • Payment Are Irreversible

Once you’ve made payment to anyone using cryptocurrency it is difficult to get the money back.

You can only get your money back after making a cryptocurrency payment if the person you paid sends it back.

Investigate the reputation of the seller before making a cryptocurrency purchase to learn more.

  • No Legal Protection:

In the unlikely scenario of a problem, credit cards and debit cards are legally protected.

For instance, your credit card issuer offers a procedure to help you get your money back if you need to dispute a purchase.

Such safeguards are generally absent from cryptocurrencies.
