Distributed P2P network is a network in which different computers are connected to each other having same blockchain on each system.So if someone tries to attack or hack the blockchain it has to change the block and the block coming after it.
Let's say you hacked a system/pc and changed the entire blockchain after a block but the connected computers having same blockchain communicate with this attacked system and the majority of right chain stops the blockchain to get hacked.
In simple words to hack a blockchain a person needs to hack at least 50% of the computers/laptops to change the entire blockchain which is practically impossible because of the computational time taken for hacking and in this period the other systems corrected the chain (or the new validated blocks get added).
Technology has a great impact on human life and is meant to make life easier and better, with this notion Web 2.0 made it easy to get the things or products easily either it's within the nation or across the boundaries. But it is failing sometimes to get the assured and authentic ordered item. Many a times the product sold is fake and doesn't show the basic details from using raw material to fine product to shipping to an address. But with using blockchain the problem can be removed as- 1- For people using product They can get to know each detail about the item and can be assured of quality used, process, manufacturing and it is because of using the concept of hashing and securing each step in making the product. It also reduces the cost price of product. 2- For people employed in industry It is seen that the person responsible for your product can be a child doing child labour which is against law. So a child can be saved from it. This is helping the people in becom...
