The block chain is an undeniably ingenious invention — the brainchild of a person or group of people known by the pseudonym, Satoshi Nakamoto. By allowing digital information to be distributed but not copied, block chain technology created the backbone of a new type of internet. Originally devised for the digital currency, Bitcoin, (Buy Bitcoin) the tech community is now finding other potential uses for the technology.
Bitcoin has been called “digital gold,” and for a good reason. To date, the total value of the currency is close to $112 billion US. And block chain can make other types of digital value. Like the internet (or your car), you don’t need to know how the block chain works to use it. However, having a basic knowledge of this new technology shows why it’s considered revolutionary.
Picture a spreadsheet that is duplicated thousands of times across a network of computers. Then imagine that this network is designed to regularly update this spreadsheet and you have a basic understanding of the block chain. Information held on a block chain exists as a shared — and continually reconciled — database. This is a way of using the network that has obvious benefits. The block chain database isn’t stored in any single location, meaning the records it keeps are truly public and easily verifiable. No centralised version of this information exists for a hacker to corrupt. Hosted by millions of computers simultaneously, it’s data is accessible to anyone on the internet.
And that is why, there’s a buzz around the term cryptocurrency and namely Bitcoin. Since the information is available over the internet and is accessible by everyone, anyone can verify each block in a block chain. After verifying these, you will provided with cryptocurrecy. This verification technology is known as Hashing and the whole process is now also known as cryptocurrency mining ( you will be familiar with this term). Any one can start mining. But, it will take more than 200 years for you to mine one Bitcoin (this is not the case with other currencies), if you are doing it individually. You can join any pool (like slushpool, the very first bitcoin mining pool),or form a pool so that, the individual power of your own system can be combined together to do mining.

To get started with block chain and to develop them, there are some courses. Some of them are:
1) Block chain course by IBM — This course is free of cost.
3) Block chain Developer Fundamentals by Udacity — This course costs around $730 (Rs 53100) but you will get the second term for free (should apply a coupon). Therefore, the effective cost for a term reduces to $365.
There are a lot of courses available other than these, on edX, Udemy, NPTEL, etc. I recommend you to read the above blog (by Blockgeeks) first and then choose a course that suits you. Each one of them has their own advantages and disadvantages.
So, get started in Block chain technology and leverage the technology to the maximum level.
