Blockchain lingo!

 Blockchain, AI and machine learning are the latest buzzwords in the IT industry. Building a blockchain is also becoming a need for various businesses. Recall, that a “Blockchain” is the distributed shared ledger for recording and storing transactions. Each of the participant in the business network has a copy of the ledger which is updated regularly.

Before building a blockchain, there are a few keywords that have to be mastered and we will discuss them today.

What is ‘Blockchain’?

Blockchain is the distributed, shared ledger system with no central authority. We have all encountered ledgers in our lives. We have our own personal ledgers for keeping track of transactions. But in the case of a large business scenario, the number of transactions is huge. The number of people keeping track of those very transactions is huge too. Each person involved in the business might have their own version of transactions. Blockchain solves this problem by each ‘node’ having their own copy of the ledger.

Asset

The Blogchatter A to Z has kicked off and I start off my set of posts primarily around the theme of technical and personal posts. My latest fascination has been ‘Blockchain’ and I am striving to do my technical posts around my latest interest. 

‘Blockchain’ is the common shared digital ledger that every participant in the business sees. In the Blockchain world, any thing that has value is  called as an ‘Asset’. Assets are sold and bought and these are recorded on the Blockchain ledger. Asset is the key aspect of Blockchain. 

Assets are further classified into tangible assets and intangible assets. Tangible assets are those that can be seen and visualized. Examples of tangible assets are car, motorcycle, house.

Intangible assets are those that are abstract and cannot be seen but they play an equally vital part in the blockchain  cosmos. Examples of intangible assets are mortgage, patent, trademark. 

Cash is yet another form of ‘asset’ but it is completely anonymous. We cannot track its movements. We don’t know who we received it from and where it will go next. 

We discussed ‘Asset’ in the Blockchain world. Drop by tomorrow as I continue my ‘Blockchain’ journey…

Use cases of Blockchain

Even as the concept of ‘Blockchain’ is bouncing off everyone’s radar and everyone is keen to know more about this trending topic – let us see more about this new and emerging technology. 

Introduction:

‘Blockchain’ is popularly associated with ‘Bitcoin’ cryptocurrency. The Blockchain system shot into prominence and more industry experts took notice of it only after Bitcoin’s surge and ultimately its downfall!

‘Blockchain’ as you might recollect from my earlier post is the shared ledger system. Each transaction is recorded and added to the shared ledger after being approved by the ‘miners’.  The beauty of ‘Blockchain’ is that each miner or node has a copy of the transaction. None of the transactions can be modified or deleted.It allows total transparency of the system with no central authority and promises complete anonymity and security.

Bitcoin and Blockchain: What next?

It seems every other day has a new headline regarding ‘Bitcoins’. I am sure most of us give a casual glance at this word and wonder where it will go next. From a humble value of $1019 on January 1,2017 the value of Bitcoin has soared to $16,860 till date. This type of meteoric rise will obviously roll a few eyes! πŸ™‚

I had already written about Bitcoins in my earlier post “Introduction to Bitcoins“. Let’s refresh briefly:

  1. ‘Bitcoin’ is a cryptocurrency
  2. It was created by a highly doubtful ‘Satoshi Nakamoto’ in January 2009
  3. It does not have any physical form
  4. It is largely based on ‘decentralised’ way of transacting business or the ‘blockchain'(no common authority to enforce regulation)
  5. It is accepted in a few countries and some goods can be bought with them
  6. Acceptance by different governments and countries is still an ongoing process
  7. In addition to its legal use,it is also used for illegal activities

What is Blockchain?

‘Blockchain’ is the underlying technology that supports Bitcoin. In simple terms, blockchain is a global ledger. Sending and receiving bitcoins are some example of transactions. A group of transactions will be considered as a ‘block’ which when approved is added to the ‘chain’. This chain cannot be deleted or changed. It is continously added and maintained by all nodes in the network.

Without a regulating authority like a bank, ‘blockchain’ has kept the Bitcoin journey alive for the past 8 years!

 

Future of Bitcoin:

I am no Bitcoin analyst and I do not have the crystal ball, but I can certainly state a few things! πŸ™‚

  1. ‘Bitcoin’ and other cryptocurrencies will continue to hold people’s imagination and urge to invest for at least a certain period of time
  2. Since it is a completely volatile currency, it is not for the faint hearted
  3. Since it is not regulated, people with disposable income are the best individuals to invest in Bitcoin
  4. Even if one would like to invest in Bitcoin, good to start with a small amount
  5. Since the technology itself is evolving and nobody understands its implications fully, better to wait and watch and understand the nitty gritty details of ‘Bitcoin’.

Whether the cryptocurrencies will stand the test of time, the underlying blockchain technology will definitely shake things up in the technology world and will most likely outlive ‘Bitcoin’!

Most of the world’s top universities including Stanford university, Princeton university and e-learning portals like udemy, Coursera have taken notice and started courses in Blockchain.
