What is Blockchain?
Even if you lived under a rock during the entire past decade, you still would have heard about Blockchain and Cryptocurrency. In today’s market, both cryptocurrencies and Blockchain are well known.
The goal behind developing blockchains was to keep a track record of online digital currency like Bitcoin. However, no one at that time could have predicted that this technology of Blockchain could have such an impact in any near future.
One cannot think of a sector in which blockchains cannot positively reform because Blockchain has been successfully implemented in ads, manufacturing, utility, and even healthcare.
But. What exactly are blockchains? To put it simply well, Blockchain is an interconnection of blocks, through which they form a chain. Do not think that these are your average block and chain we are talking about. The blocks here in question are pieces of information, and the chain is actually any public database.
Because of such “block” and “chain” design, blockchains are actually decentralized. This means that there is no one particular central database in which you will be able to find all the data that is stored in the Blockchain.
The same decentralized nature also allows the blockchains to be a lot flexible and secure because hackers would have to go from node to node in order to gain all the information.
Since all the databases in nay blockchains are public, it means anyone would be able to see all the information in the Blockchain (they have to be a member of the Blockchain to be able to do that.) This fact also allows blockchains to be transparent, unlike the traditional form of centralized.
All the benefits, as mentioned earlier, allow blockchains to have such a wide application. Then it should come as no surprise to anyone when we say that even the jobs in the sector are increasing. More importantly, the CTC for any blockchain job is easily in the eight figures range (Indian National Rupees).
The lack of formal education that teaches Blockchain allows this market to land into the hands of thousands of people online. In a sea of online courses that feel similar to each, we come in to help you come to a decision. We have done our research, and we are ready to present you with what we feel to be the best online blockchain courses and best blockchain courses.
But before we discuss our picks, we feel it’s our onus to equip you with the right tools to be able to make the decision yourself.

How to Choose a Course?
So, listed below are some tips which should help you make the final decision:
1. Course Contents and the Teacher
When you are doing your preliminary search of any best online blockchain courses, you should look at the course contents that are being and who the teacher is going to teach you. You should be able to eliminate many courses with this simple method.
Just look at the trial video that is available on any course page. That should give you a fair bit of idea of how the teacher is and are you guys on the same wavelength.
2. External Resources
Generally, it is seen that courses tend to bundle in a lot of useful resources, which could prove to be different in many cases. For example, imagine the course is about machine learning using MATLAB, and the course provides you with a MATLAB license for the duration of the course (MATLAB is a licensed software for which you would have to pay extra).
How good that would be! You could find many such deals. So, always look at all the resources that they will provide you.
Technically speaking, money is one deciding factor. Many people find their ideal course only to find that it is too costly. We understand that, however, we have seen people go in a completely different direction as well.
These people sort the courses from low to high and pick the first one without even determining the course’s quality. We believe treating money as a metric this way is an entirely wrong way to go about it.
Instead, you should look to maximize the amount of learning you will be getting out per rupee that you are spending. We believe doing your math this way would allow you to find some really high-quality courses without having to spend much.
The knowledge that you have just gained should prove the perfect Segway for our list of the best blockchain courses.

What makes Blockchain important?
Most of the companies make use of data, especially financial data, to run their companies. If the data is made available quickly and accurately, the companies get the benefits. Blockchain technology helps companies access the information accurately and promptly through a secure and transparent medium (known as a ledger) to authorized members of the Blockchain network. A blockchain network also offers the facilities of tracking transactions, orders, payments, production, accounts, etc. The ledgers in Blockchains are immutable, and the details of the transactions are made available to all the members. Lastly, the best part about Blockchain is that anything that holds value can be tracked and traded on a blockchain network, which reduces the risks and cost.
What are the key elements in Blockchain technology?
There are three key elements in Blockchain technology that are a must for the proper functioning of the network. The first is a distributed ledger's technology. Because of this technology, all authorized network participants have access to the distributed ledger and its immutable record of transactions. The second element is immutable records. Since the records are immutable, no one can alter or tamper with a transaction after being logged into the shared ledger. In case of a wrong transaction record, a new transaction is added and both the incorrect and correct records exist. The third and most crucial component is smart contracts, a collection of rules stored on the Blockchain network and executed automatically to speed up transactions.
How does Blockchain work?
On a blockchain network, a digital transaction is merged with other transactions that happened during the same time period in a cryptographically secure block. The block is subsequently transmitted to the whole network. The nodes, or participants, in a blockchain network, validate and send transaction data. The block of transactions is verified by miners, who use processing power to solve a cryptographic problem and validate the block of transactions. A reward is given to the miner who solves and verifies the block first. A chain of blocks is formed when each verified block is linked to the block before it. A key cryptographic component of blockchains is the hash function. Blockchain hashing power creates a reliable, instantly computable, and preimage-resistant system.
