All you need to know about Cryptocurrency and Blockchain Technology

Time is money, and both time and money are evolving rapidly. The discovery of the internet disrupted the way the world operated, bringing political, business, economic and social changes. It improved business processes and made online transactions, and banking, among other things, quicker and less complicated. And this is just the beginning; we humans are, after all, constant inventors and innovators.

Traditionally, political, economic, and legal systems structures are defined by contracts, transactions, and records. Nations and organisations set boundaries of operation to identify and chronicle managerial and social events.

But now it’s time for economic transformation. However, the slow and administrative regulations are stifling the digital transformation. 

Blockchain technology is here to help!

What is Blockchain?

Blockchain is an open, distributed technology that enables the process of recording unalterable transactions and tracking assets. Blockchain works on five basic principles:

  1. Distributed database
  2. Immutable records
  3. Transparent access
  4. Algorithm-based computational logic
  5. Two-way participant transmission

Blockchain gets its name because of the way the transactions are grouped together into blocks of data, then chained together by way of a mathematical function that creates a hash code

Blockchain has disrupted the business industry with its application in financial services, healthcare, artificial intelligence (AI) and the internet of things (IoT) for supply chain, retail sector, oil and gas, telecommunications, insurance, smart contracts, voting and crypto of course.

So, how do blockchain technology and cryptocurrency work together?

Since its first implementation in 2009, blockchain has not been well known. Blockchain technology is the foundational technology for cryptocurrency, which was first implemented just a decade ago but was revolutionised with the widespread use of the application by Bitcoin. Bitcoin was the first cryptocurrency and operated through blockchain.

Blockchain is the foundational technology for cryptocurrency

Blockchain made it possible to record bitcoin transactions without a central authority establishing trust in a trustless environment. Being a digitalised, decentralised, public ledger, blockchain allows the formation of digital information into blocks, which are stored across a network of computers, creating a database. When verifiable transactions take place, the data is stored in blocks, which, when complete, are added to the chain.

Cryptocurrencies like Bitcoin, Ethereum, Litecoin and, USD Coin are used to buy goods and services. And cryptocurrency uses blockchain, an enhanced cryptographic security system, as a public ledger with immutable records that cannot be deleted or altered. 

Cryptocurrency is used as a digital form of cash to buy goods and services through various trading platforms or digital wallets. The blockchain technology here records the transaction when ownership is transferred to the new owner. Every transaction, therefore, is a public ledger, unalterable, secure and time-stamped.

The pace of technology will not slow down. Cryptocurrency and blockchain hand in hand continue to disrupt much more than the financial services industry.

    Good article!

    Blockchain is best know for cryptocurrency, but it has a lot of potential in other areas such as smart contracts for real estate and procurement. Even the ledger format of blockchain allows for more utility usage on banking, data/information storage and customer service.

    The article was a good introduction to blockchain.
    The anonymity of the transactions seems to be a great concept, yet after trading in crypto for a few years now, I see room for third party oversight. I’m my opinion oversight is required to make crypto-currency viable in the long run. Work completion, (proof of work) and contracts seem to be part of the solution. I feel that we still need oversight to limit underworld trades or at least force those currency streams into the light where it can be monitored and if interdiction is necessary, the third party would be able to act. This of course subverts part of the idea of a strict two party transaction or contract. Unfortunately there are enough criminals who will move their currency across these unmonitored networks and continue to prosper by contributing to our global ills.
    A third party, though not ideal, seems to be the only way. Crypto-currency would have more attributes of fiat currencies that can be tracked and even devalued as it is misused.

  3. I’m starting to think I need to reconsider my own thoughts on this topic. That’s how highly influential your views are in this article. I’m sure I’m not the only reader who feels this way.

  4. Thanks For Sharing This Article. It’s Very Much Helpful For Us. To Understand The Digital Currency.
    codes are created by a math function that turns digital information into a string of numbers and letters.
    If that information is edited in any way, the hash code changes as well.
    Waiting For The More Exclusive Articles LIke This. Once Again Thankyou So Much For Sharing.

    Amazing article. Thanks for sharing. Its very helpful for people like me who is gathering knowledge about digital currency. looking forward for some more helpful content from you.

  6. Great Article,
    That’s amazing your information is really valuable to me, I didn`t know much about blockchain and cryptocurrency. but I always want to know some informative information related to this, you helped me thanks for that. I have a question for you “is cryptocurrency replacing the currently used payment methods”?

    • Hi, It’s good to know that the blog helped you learn more about Cryptocurrency and blockchain. To answer your question, no, cryptocurrency is still in initial stages of currency evolvement, where traditional payments methods cannot be replaced fully.

  7. This is an amazing article; thank you for sharing it! Blockchain technology is rapidly evolving these days, and most people are unaware of blockchain app development. looking forward to more great content!

  8. Well, NFTs are also a concern in terms of environmental impact because they are stored on blockchain networks that consume a significant amount of energy
