What Is Blockchain Technology : Blockchain technology is a technology that leads to a chain of blocks, containing digital information stored in a public database. It is a distributed database existing on multiple computers at the same time, which constantly grows as new sets of recordings or blocks are added to it.
How Does Blockchain Work : Blockchain consists of three important concepts: blocks, nodes and miners.
What Are Blocks :
* Every chain consists of multiple blocks and each block has three basic elements:
* The data in the block. A 32-bit whole number called a nonce. The nonce is randomly generated when a block is created, which then generates a block header hash.
* The hash is a 256-bit number wedded to the nonce. It must start with a huge number of zeroes (i.e., be extremely small).
When the first block of a chain is created, a nonce generates the cryptographic hash. The data in the block is considered signed and forever tied to the nonce and hash unless it is mined.Source : News on Air
