Blockchain - A new era of internet

Blockchain is a technology built using existing set of technologies that provides a list of records called `blocks` which together forms a chain. This a highly secure and transparent to keep the records that are distributed.

In simple terms, a time-stamped series of immutable records of data that is managed by a cluster of computers not owned by a single entity.

Blockchain can be public(permission-less) and private(permission-ed).  Ethereum is one of the public blockchain whereas Hyperledger Fabric is permission-ed/private.
