What is Blockchain? How does it work?

In this video, we're going to learn about "Blockchain system".

How can Blockchains solve real world problems like voting systems.
We need to understand, implement, and develop a Blockchain based applications, because Blockchain is the cutting-edge of technology.

By allowing digital information to be distributed but not copied, blockchain technology created the backbone of a new type of internet. Originally devised for the digital currency, Bitcoin blockchain, (Buy Bitcoin) the tech community has now found other potential uses for the technology.

A blockchain is, in the simplest of terms, a time-stamped series of immutable records of data that is managed by a cluster of computers not owned by any single entity. Each of these blocks of data (i.e., block) is secured and bound to each other using cryptographic principles (i.e. chain).

The blockchain network has no central authority — it is the very definition of a democratized system. Since it is a shared and immutable ledger, the information in it is open for anyone and everyone to see. Hence, anything that is built on the blockchain is by its very nature transparent and everyone involved is accountable for their actions.
