Blockchain Basics

Blockchain Possibilities

A permanent secure digital distributed ledger was the simplest definition of Blockchain that emerged in the previous post from this series. A long conversation on the possibilities with blockchain resulted. As the ideas were wrestled with, the contours for further conversation needed to be sealed. And this post is just that. The contours for further conversation.

Truth be told, none of these above terms are missing in the world of technology today. We have secure databases, digital databases, distributed ledgers even. Why then, is Blockchain considered as the messiah of the internet? Why is it said that the ‘world wide web’ is about the exchange of information and Blockchain will be about an exchange of value?

The industry is expecting Blockchain to be able to resolve world hunger, serious! Proponents claim Blockchain will make it easier to trace ‘blood diamonds’, something that has plagued us for decades. Be able to reduce and even eliminate accounting fraud. Think Enron! Voting in the elections. Moscow and NASDAQ are in the process of deploying Blockchain for electoral and shareholder voting to prevent fraud.

Now take a giant leap across and Blockchain supporters believe that it will make it possible for you and me to borrow from peers and not just depend on a bank. A completely new fundraising mechanism. The currency exchange guys believe that Blockchain will reduce their transfer transaction times from days to seconds. Tough to imagine that level of improvement in productivity and efficiency. Days to seconds! Wow. Artists are singing praises because they believe Blockchain will deliver them from the clutches of record labels who corner more profits than the artists for their work.

Look around you, intermediaries in every industry sector and transaction garner far more value than the buyers and sellers. Think of the farmer getting a pittance for his produce while you pay escalating prices for greens.  With intermediaries a.k.a traders/middlemen earning a significant chunk.

A world without intermediaries. Really?

Summarising the possibilities gets this list below to emerge. A broad cull from all the herd of hype about Blockchain.

• Transparency and Privacy (yup together!)
• Improved Traceability
• Immutability
• Enhanced Security
• Decentralized
• Faster Transactions with reduced costs
• Trust or rather Trustless

The above possibilities emerge in the way many of these existing technologies of Digital databases, distributed ledgers have been intertwined with newer concepts such as Consensus Protocol, Smart contracts, Proof of Work, cryptography to create the Blockchain framework. Thereby unleashing immense possibilities and benefits.

Each of these sits well for deeper conversation and exploration. And will soon come here too.

There are much jargon and ‘big’ words in the post. Thereby straying a distance from a key objective of keeping it simple. That is part of the challenge that is being wrestled with.  With time, practice and deeper conversation and real work, this space will read better.

Jump in. Let’s keep the conversation going. In our own small pockets and larger forums. We’ll get somewhere.

 

Blockchain Basics

Well if you are like me, you have heard this word ‘Blockchain’ bandied about. You have read and heard so much about it in the news yet you wonder if you really do understand it. It can seem that everyone is talking about blockchain and ledger technologies, but the truth is most of us are not yet up to speed, just like me! What Blockchain is and ‘could be’ is fuelling industries the world over. Everyone seems to be seeking possibilities. So, what are some ‘Blockchain Basics’? 

In this space, I along with a colleague, will try and explore an understanding of the technology and possibility called Blockchain. We invite you to join us. We will attempt to understand Blockchain and it’s many terms in as simple a manner as possible, through this series. 

‘What is Blockchain’, is a good place to start.

In a nutshell, Blockchain is; A permanent secure digital distributed ledger.

Am sure that meant nothing! It didn’t when we read it the first time and was trying to understand what Blockchain was about.

Let’s see if an example makes it any better. Something we can relate to, an excel sheet?

Think of Blockchain as an excel sheet which is open on all computers in the network. Any changes being made to the excel will be visible to all in the network as it is being made. It hence always is transparent and in a state of consensus. To be clear, it is not one excel in a central location shared by hundreds of computers. It is hundreds of copies of the same excel stored on hundreds of different computers across the world.

It also makes the data secure. Think of a hacker who has to erase the data from hundreds of systems to alter anything; earlier all he had to do was change it on ‘one’ master system.

Let’s try another example exploring why the world is falling over itself imagining the immense possibilities Blockchain holds.

Blockchain Basics with an example

Let’s assume that ‘you’ have a file of financial transactions on your computer. Three accountants have the same file stored on their computers. As you make another transaction buying something, your computer sends an email to each of them informing them of the transaction.

All three accountants rush to be the first one who will verify if the transaction is correct and you can afford the ‘buy’. The first one who verifies the transaction shares the logic with all the other accountants and gets paid a salary. If the other accountants agree that the transaction is correct and you can afford it, then everyone updates their excel sheet automatically.

This whole concept is nothing but Blockchain Technology.

If you wanted to indulge in tech-geek speak, here is your way to do it. 

And voila you got geeky! Next time let’s explore some of these terms Proof of Work, Distributed ledger, Consensus Protocol, Smart contracts and see what we see…

 

Until then here are some links for you to explore what Blockchain is, one is a video featured on OWL (Our Work is Learning) Newsletter which explains Blockchain to a toddler and professional.

Another one I found useful which explained Blockchain in simple English is here

What do you think? Your comments would be great to help evolve an understanding. Thanks much.
