Block and chain, because the word suggests, a sequence made of blocks! So we determine what are these blocks. Blocks certainly are a kind of database! People who work with computers know databases well! And for people that do not know, whenever we say in simple language, then a database is known as Collection of Data! Data, little else, whatever information you type on the computer, that details are stored inside electronic form in the computer! Similarly, every information about the Internet is a type of data! And this is often a collection of data database! This database is kept in the computer so that it can be searched.

In blocks, the database is collected in groups which group is named blocks. Each block features a limited space or capacity to collect the database! And whenever a block is entirely filled using the database, it really is automatically from the next block! In this way one block gets attached with another block! And there’s a series! This is what is termed the chain of blocks, which is, the blockchain!

What include the elements of Blockchain?

There are three types of elements in a blockchain-

Data kept in blocks

Hash (Transition Hash) generated from that transition

Hash.(Previous Hash) from the first block connected with that block

Note – The first block inside blockchain is named the Genesis Block!

What are nodes in blockchain?

The computers which blockchain information is stored! They are called nodes and all the nodes which can be connected to the blockchain use a copy of the blockchain! Which updates every 10 mins! With the help of these nodes, it could be found out using a Hash make certain there has become no change in it. If all the transitions within the blockchain are approved by the nodes, that’s, the proof work is approved, chances are they’ll are designed in blocks! With the help of nodes, the data in the blockchain is stored, spread and preserved. A copy of every transition made in the blockchain on each of the nodes is updated every 10-10 mins! That’s why it can be considered safe!

How does blockchain process?

Each block includes a cryptographic hash of the previous block which is generated on every transition made inside blockchain! Hash can be a string of numbers and letters. That is, Hash can be a mathematical function that encrypts the input data in to the output of a fixed length. So, no matter the size with the input data, the Encrypted Unique Hash is usually of a hard and fast size! And at the same time it can be also from the Hash made from the previous block’s transition!

Why is blockchain technology considered secure?

If someone would like to edit the database of the Blockchain Technology, another new hash is generated! Due to which the setting of most after blocks is changed and it is easy to know where the setting has become changed! So no one can tamper with the information on this blockchain! Now if you already know that you must make some changes in the block chain, then you have to show the evidence of work, that is, for whatever changes you’re going to make, all of the computers (Nodes) coupled to the blockchain need to make this change. The information has to be sent and only if the majority from the computers approve, then you can definitely change it!

Where can blockchain technology be used within the future?

In preventing corruption

Yes, corruption can be prevented by utilizing blockchain technology because whatever database is kept in the blockchain is copied on every nodes if anyone desires to change your data then everyone else will know regarding it!

In maintaining government records

The utilization of blockchain technology in government offices can prove to be very secure.

Anyone whose name is held in the database cannot be changed while exchanging properties using Blockchain technology! Due to which any disputes regarding properties can come down.

Patient record keeping inside the hospital

If all the information associated with patients is kept inside the blockchain, this will be correct and anyone will probably be able to jump on.

In virtual currency | In Cryptocurrency

People previously started investing within the cryptocurrency you are seeing in the online market like bitcoin, ethereum, dogecoin etc and this currency is increasing faster than gold! One advantage with this is that it really is decentralized i.e. it does not require any middleman like in the ordinary currency we use, we have to use banks to transfer money in one place to another! And they also charge some fees because of this, banks will never be needed inside the transition to Cryptocurrency! And you is going to be able to transact with crypto currency anywhere inside the world!
