Here, I will show you a rundown of cryptocurrency and blockchain technology.

While many people are familiar with the terms crypto and cryptocurrency trading, the technologies involved and the mechanisms for how the processes work are often misunderstood. 

Whether you are an active cryptocurrency trader or simply interested in learning more, understanding the rundown of cryptocurrency and blockchain technology is essential. This guide is here to help you better understand what technologies are used in cryptocurrencies and blockchains. 

What Is Blockchain Technology? 

What Is Blockchain Technology

A blockchain is a form of a decentralized ledger that stores all transactions and tracks assets across a peer-to-peer network. A blockchain acts as a form of database that stores information electronically. 

Blockchains play a vital role in cryptocurrencies such as Bitcoin, as they maintain a secure and decentralized record of transactions. 

What makes blockchain technology so different from traditional databases is the way that it is structured. 

A blockchain collects information together into groups, which are known as blocks. These blocks have a certain level of storage capacity. Once the blocks are filled, they are then closed and connected to the previous block, forming a data chain.

Other Technologies To Know 

technical blockchain terms

Some other technical terms that you will likely encounter when you enter the world of cryptocurrency trading are listed below: 

  • Wallet

Your wallet is the location where you will store your cryptocurrency holdings. Wallets are either hot, which is online and software-based, or cold, which is offline, stored on your device. 

  • A Smart Contract¬†

This is an algorithmic program that enacts a contract automatically based on a code. 

  • A Private Key¬†

This is an encrypted code that will allow you to access your cryptocurrency directly. 

  • A Public Key¬†

A public key is a name for your wallet’s address that acts like a bank account number, allowing you to share your information with others so you can send or receive cryptocurrencies. 

  • Node¬†

This is the name of a computer that connects to a blockchain network. 

  • Hash¬†

This is the unique string of numbers and letters that identify blocks that are then connected to cryptocurrency buyers and sellers. 

  • Exchange¬†

An exchange is a digital marketplace location where cryptocurrency traders will buy and sell cryptocurrency. Exchanges can also be used to find out more information about the history and standing of a cryptocurrency. For example, you access OKX’s Ethereum live price charts to gain more knowledge about your trading opportunities. 

  • Decentralized Applications¬†

Decentralized applications, otherwise known as DApps, will exist on a blockchain with the purpose of allowing users to carry out actions without any intermediaries. 


The majority of cryptocurrencies out there exist without backing from a central bank or government. Instead, cryptocurrencies exist with the help of a decentralized technology known as blockchains.

Not only do cryptocurrencies not have the banking of physical banks, but they also exist without the need for physical notes or coins. Instead, cryptocurrencies exist online as virtual tokens that can be boarded or sold for different values depending on the market forces.

A cryptocurrency is formed through a process known as mining. Mining involves using computer processing power to solve a series of complex mathematical problems to earn coins, which is both resource and time-intensive. The only legal way to obtain a cryptocurrency other than mining is to buy the currency.

A Simple Rundown of Cryptocurrency and Blockchain Technology: FAQs

Cryptocurrency and blockchain technology are hot topics, but can be confusing. Here's a breakdown in frequently asked questions:

What is cryptocurrency?

Cryptocurrency is a digital form of money that uses cryptography for security. Unlike traditional currencies controlled by governments, cryptocurrency operates on a decentralized system. Transactions are recorded on a public ledger called a blockchain.

How does blockchain work?

Imagine a shared record book, accessible to everyone, where transactions are chronologically listed. This is essentially a blockchain. Each entry (called a block) contains transaction information and is linked to the previous block using cryptography, creating a secure chain.

What are the benefits of blockchain?

  • Security: Cryptography makes it nearly impossible to tamper with data on the blockchain.
  • Transparency: Everyone can see the transaction history, promoting trust and accountability.
  • Decentralization: No single entity controls the blockchain, reducing reliance on central authorities.

What are some popular cryptocurrencies?

  • Bitcoin (BTC): The first and most well-known cryptocurrency.
  • Ethereum (ETH): A platform for building decentralized applications (dApps).
  • Litecoin (LTC): Often seen as a faster and cheaper alternative to Bitcoin.

How can I buy cryptocurrency?

Cryptocurrency can be purchased on cryptocurrency exchanges using traditional money like USD or EUR.

Is cryptocurrency a good investment?

Cryptocurrency is a highly volatile and speculative market. While some have seen significant gains, there's also a risk of losing your investment.

How is cryptocurrency used?

  • Digital payments: Some merchants accept cryptocurrency for goods and services.
  • Investment: People buy cryptocurrency hoping for future value appreciation.
  • Decentralized finance (DeFi): Blockchain enables new financial applications like peer-to-peer lending.


Blockchain technology is still evolving, but blockchain has the potential to revolutionize various industries beyond finance, such as supply chain management and voting systems.

It's important to do your own research before making any investment decisions related to cryptocurrency.
