What is a Blockchain?
Extreme large set of sequential records which are broken into blocks and united by chains creating a link between each other. These links are created using hashes. Hashes are irreversible (one-way) functions which does a tit-for-tat. You give an input and hash generates a hexadecimal hash as an output. Here, we cannot determine the input unless we know the output. So this way the hashes are unique to the input given. And this 32 character hexa-decimal output carries encryption which cannot be decoded easily. For example: Harry is trying to tell his friend a number without actually revealing the number, harry hashes out “fu75seh3aumrer7343873934njd34df” which will be generated only if the input is 87. So hashes form the basic data securing part of the Blockchain.
Who can learn Blockchain?
With a good understanding of python and server responses and requests like HTTP/HTTPS you can get the most out a Blockchain programme. The recent version of python 3.7 along with a pip.
How can you learn?
Learning Blockchain technology can sometimes be hard without the proper resources in places. We would suggest you to take up a professional course and get certified on Blockchain for better learning and career. Now, let us see the basic structure of building a Blockchain:
Building a Blockchain:
- Represent the Blockchain – Build a chain that will be class to which creates a list and stores transactions
- Look and Feel of a Block – Each block looks like a unified indexed timestamp
- The previous block hashes are shown in the next block
- Add transactions to the block
Create a proof of work (PoW) for decoding the hashes using python
- Creating an API framework with Blockchain:
- Put the Blockchain into work:
- Centralized the Blockchain:
- Create a consensus algorithm
- Create new nodes
- Implement the consensus code
The above is a sample tutorial which you will find online too. The whole challenge lies in creating a Blockchain framework for real-time data. If you are learning Blockchain for a job, it is always advised to learn other important language Python. Python tutorial are given by industry experts in India and we can find most of them online. Since Python has become an essential factor for learning Blockchain, the existing python experts are getting an edge over others who do not know. There are other languages through which we can do Blockchain, but python is preferred all-over due to the flexibility of the language.
It is interesting to see the IT space growing and evolving. In today’s world, Blockchain has become a household name and everyone is interesting in knowing about it as the synonym for Blockchain create by media is “Money”. Engineering is no longer the most chased after and it would be great to see colleges adopting to latest technologies and bring it in their syllabus. All these will happen towards the better of the people, if not for the business.
