Once again, we run into a product of that inventive genius who went by the pseudonym, Satoshi Nakamoto. And I thought he/they just made Bitcoin. Silly me.

The Beginning

Why Was Blockchain Needed

Satoshi needed a way to keep track of Bitcoin. Who owned how much, where it was stored, etc. Otherwise, it would so random and hacked that BTC would be beneath useless. Blockchain was invented to hold that information in a safe, distributable, and not copiable way.

With blockchain technology, Bitcoin could be mined and transferred safely across the digital world. Everyone using BTC was using blockchain technology.

Evolution Of Blockchain

This new way of transferring digital finances did not unnoticed. People realized how to separate blockchain from digital currency and began using it as a means of holding, logging, and moving all kinds of digital valuables.

Research was being done by almost every major financial institution. Blockchain went from being a novel way to handle cryptocurrency to be a fantastic new medium for transactions of all sorts.

What It Does

“The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value.” – Don & Alex Tapscott, authors Blockchain Revolution (2016).

Stores Records

We had paper ledgers, then computerized databases and spreadsheets. These could be kept privately, hidden, erased, hacked, copied, and/or forgotten. It also took humans to input most of the information. We know what that means.

If I buy an online book from you through Amazon, I transfer money from my bank to Amazon. Amazon gives you your share after it gets its percentage, then you see the money in your account and send me the link for the book. Sounds simple. What if your bank says it never got the money? What if the link is broken? What if Amazon is hacked?  What if someone hacked your PayPal account?

With blockchain technology, the money, book, and transfers are all visibly stored and moved in digital blocks. One block transfers its information to the next block that adds its information and so on. All in real-time, visible to all. It can’t be duplicated and there’s no point in hacking it. Done deal.

Moves Records

These little blocks just create more blocks, storing a little compact part of themselves in the next block so the data is seamless. The process takes a few seconds to complete.

From block to block and new blocks made along and no old blocks lost. How exactly this all works is beyond the scope of my little article.

Who Uses Blockchain

Digital Currencies

It was started along with and for the service of digital currency; it goes without saying that most all altcoin would share the usage with Bitcoin. Blockchain technology is 100% free. If I want to exchange digital currency with you, the only charge will be a fee from the app that handles the transaction.

More of these online digital wallets are becoming available, and the fees vary. I use Coinbase, which is great for low-level holdings. Big time users will often have their own little high-tech devices that store all their data behind highly encrypted passwords.

These People Are, Too

  • Banks
  • Pharmaceuticals
  • Fashion
  • Cross-border Payments
  • Food Safety
  • Humanitarian Crises
  • Jewelry

(Did I just get lazy? Let’s move on.)

Who Is Resisting Blockchain

Why would anyone resist blockchain?  Developers are in high demand! Why not join forces? Well, some people get too comfortable in their current soon-to-be-redundant positions, and they won’t learn to use their skills for the new era.

Title Insurance

There is speculation that blockchain could make the whole billion-dollar title industry obsolete. Others say this scenario is unlikely. As the industry struggles with the challenges and opportunities of blockchain, a better picture of anticipated impacts is forming.

Arguments include the idea that since blockchain is virtually impenetrable, the duties of title companies in investigating fraud could become obsolete. Others insist that title companies do more than just investigate fraudulent documents, and therefore will continue to be necessary.

Public Records Agencies

You would think this wouldn’t be an issue since computers and the Internet have been around for so long. Yet, some say that most aspects of these agencies will become redundant. The arguments are beyond the scope of the average beginner’s article – some other time.


Ripple XRP is an international payment system that works around Visa. However, with Visa switching to blockchain and also beginning to utilize LiteCoin, Ripple’s future is uncertain.

It already struggles to maintain world dominance even though it is recognized by the World Bank. It seems that Ripple XRP has strong proponents. Trillions are at stake!

Middlemen, in general, are being made redundant. With blockchain flawlessly transferring data by itself, at the whim of the companies and individuals involved, who needs a middle man?

This idea puts certain large companies, such as Fiverr and possibly even some elements of Uber, in a position of uncertainty.


That’ s all peanuts in the grand scheme of things. Perhaps this article has a little too much of this and too little of that.

  1. Great article! I’m glad you wrote to those people who are absolute beginners (like myself) in this topic! I heard about bitcoin beforehand, but found it too risky to invest in. This blockchain system though sounds like a great and totally transparent way of dealing with crypto currencies.

  2. Hi Cathy,
    I have never heard of blockchain before so it’s always great to be educated about something new in very simple terms, otherwise I wouldn’t have a clue!
    I guess technologies like this are inevitable as we progress and move forward, but I always think that even if old jobs become obsolete, new ones are usually created (or old ones evolve and adapt) in the process.
    I like the sound of blockchain technology from a customer perspective. I like to know when I make a transaction online that my money is safe and secure and they are offering this vital service. Good on them!

    1. Thank you for the comment, Stefanie! Blockchain was being implemented right under our noses and I was completely unaware. Sometimes it’s great to know what financial institutions are up to. I agree with your ideas completely. 🙂

  3. Wow I honestly didn’t know that much about Blockchain technologie until I read this article. I feel like I need to read more of your posts to understand more about this “new” technologie. I was a little surprised to see that Visa was switching to Blockchain tech.
