BlockChain

In Blockchain, there are blocks which contain information and these blocks are interlinked forming a chain  

it is basically a collection of records > linked each other with blocks > are strongly resistant to alteration>protected by cryptography 

blockchain is not only used for a cryptocurrency(Bitcoin)  but we can use this in many other sectors for storing data safe like keeping medical records, land records, keeping any companies data safe     

there are 3 special characteristics of blockchain, making it unique and talk of the town 

1)The way it tracks and stores data: it doesn't change the already stored data information instead it adds a new block with information to the chain, it uses ledger method that is a chain of blocks related to the particular transaction are considered as a ledger, whenever a change happens it simply opens that ledger and adds one more block with information to the chain

it decentralizes its data across no of computers and networks this way no one can tamper the data if one can successfully tamper the information in one computer but they can't do so to all the computers which have the data so hacking or tampering data is impossible

2)Building trust in data: before adding a block of information to the chain a computer solves a difficult cryptographic puzzle (this is creating a block)

 then the computer which solved the puzzle shares the solution with many other computers in its network(This is known as proof of work)

the network of computers then verify the proof of work if the solution is correct then only the block of information will be added to the chain

the combination of solving complex cryptographic puzzles and verification by many computers makes this process highly secured   

 3)No more intermediaries: let us take an example of a land record dispute between two people there will be a lawyer who acts as intermediary and he keeps all the data with him and for that, he takes a huge amount of money and also its time consuming with the help of blockchain we can store all the land-related data safely as no one can temper them and we can show the data whenever required this way blockchain removes the intermediaries and thus saves a lot of money and time 

and when we use blockchain for bitcoin transactions there will be no transaction charges and there is no scope of failure or pending of transactions as it happens in case of banks due to issues in their servers blockchain servers are always active 

Business opportunities: blockchains immutable ledgers are helpful in continuously tracking realtime data, thus blockchain can be used in various sectors such as 

Supply chain management, 
banking, 
finance, 
healthcare, 
legal, 
insurance,

cryptocurrency exchanges
