Blockchain Revolution Summary

Imagine you want to buy someone’s house. You’re sure you want it, but once you start the buying process, the person selling says they don’t want any notary or bank involved in the process. Does a red flag go up? 

In today’s world, we rely on middlemen to make sure a transaction is done legitimately. They have an important purpose because they put both the seller and buyer at ease that everything happens in a fair way. 

 However, if we know anything from history, it’s that middlemen like banks aren’t 100 percent trustworthy. Banks can go bankrupt and even lose your money. But imagine a world where we don’t need a middleman, where transactions can be trustworthy and transparent for both parties. 

This system actually already exists on the internet, and it is going to radically change everything we know about money. In Blockchain Revolution: How the Technology Behind Bitcoin is Changing Money, Business, and the World, we explore the exciting and revolutionary technology that makes up Bitcoin.  

Authors Don and Alex Tapscott reveal just how different our world could be if we fully utilize the technology known as the blockchain.  In doing so, we could not only cut out unnecessary middlemen but have a completely transparent financial system finally free of corruption and dark money. Pretty crazy, right? 

These are 3 of the best lessons the book teaches:

  1. It’s nearly impossible to tamper with the blockchain.
  2. Using blockchain makes everything about finances quicker, cheaper, and more equal than our current banking system.
  3. Blockchain has many uses, including privacy and transparency.

Let’s get right to it so we can understand why blockchain is so cool!

Lesson 1: Tampering with the blockchain is almost impossible.

First off, you might be wondering why we call it “blockchain.” Put simply, every transaction is recorded in what’s known as a block. Each new block is linked to the block before it, making it like a chain.  

Each new block placed on the chain contains information from the previous block as well as its own information. When a new block is added, its data is broadcast across the network and a consensus algorithm is triggered. This system makes the blockchain virtually impossible to tamper with, because everything must line up perfectly. 

The proof-of-work algorithm is a way Bitcoin ensures that records are accurate without a central authority figure. It is used to create a new block on the chain. But to confirm a transaction and build a new block, so-called miners must compete to solve complex mathematical problems that need huge amounts of computer power. The miners get rewards for solving the problem correctly with cryptocurrency.  

It ensures that when new blocks are added to the chain, the others behind it cannot be removed and replaced. In order to pull this off, someone would have to create blocks faster than all of the computers on the network and have enough power left to solve the math puzzle. 

But doing this wouldn’t even be worth it anyway. The cost of that kind of computational power would be more than whatever you could get through manipulating the blockchain. All of this is to say that the system is extremely secure.

Lesson 2: Our current banking system is much slower, more expensive, and less equal than blockchain.

Have you ever tried to make a transaction or deposit and you were told you would have to wait one or more business days for it to go through? You might wonder why this kind of thing is still taking so long when you can email someone and they receive it instantly. It goes to show how outdated our financial system is. 

Banks are unnecessarily slow and complicated. Even if you’re doing online banking, you are slowed down by a myriad of middlemen. Examples of these middlemen include investment banks, credit card companies, security firms, stock exchanges, and more. These middlemen make things slow, and even worse, they make things more expensive and profit from it. 

The crazy thing is, Bitcoin could eliminate all of this. They take only about 10 minutes to be transferred directly from one account to another account with no middlemen like you would have with a credit card purchase.

Besides being slow and expensive, banks don’t help the poor. Because of their complicated and expensive way of doing things, a payment of under 20 cents isn’t profitable for them. A staggering 2.2 billion people in the world are living on less than a dollar every day. This is partly why 2.2 billion people don’t have a bank account. 

In contrast, blockchain could provide many of the services a bank could at no cost since it handles small payments. All one would need to use blockchain is an internet connection, making this form of money much more accessible, and not to mention globally universal.

Lesson 3: You can use blockchain to allow for transparency or security.

One of the big problems facing our modern world of technology is how we can keep our personal information safe online. Blockchain could also help us in this area, because transactions allow you to have both transparency and privacy, depending on the situation. 

Blockchain users have the option to choose their level of privacy by using cryptographic keys that can be their signature. Anyone can protect their privacy by choosing to use a new signature each time they make a transaction. But they can decide whatever level of privacy they want. 

Government organizations and NGOs could choose to use the same identifiable signature on all transactions. Why? So the public could track their spending and know they can trust them. For the first time ever, governments could use blockchain and show taxpayers how exactly their money is being spent. 

Blockchain also lets you manage your presence on the system by using smart contracts. These are where you pick and choose what data can be shared with authorized people and what stays private. For example, if a cop pulled you over, you could choose to give them temporary access to your personal data. They could quickly and easily see in the database that you don’t have a criminal record. 

If you wanted to earn some extra money, you could give out pieces of your personal data to an advertising or marketing company. You could even donate information to medical researchers who need it and all the while keep your identity secret.

Blockchain Revolution Review

Technology is so cool and so is Blockchain Revolution! I’m so excited to learn about all of the advances we’ve made recently when it comes to our monetary system. I can only hope that society and the government will fully adopt things like the blockchain so that we can improve the awful inefficiencies in our financial system.

Who would I recommend the Blockchain Revolution summary to?

The 46-year-old that’s tired of having to deal with slow and insecure banks, the 73-year-old who wants to get caught up on the current money trends, and anyone that wants to understand blockchain so they can be prepared for the future.
