What is Blockchain?
Blockchain is a growing list of records, called blocks, that are linked together using cryptography functions. Each block contains a cryptographic hash of the previous block (leading to Genesis block), a timestamp, a proof-of-work or similar form of block authentication, and transaction (or other) information.
Blockchain is core technology that powers the cryptocurrency such as Bitcoin, Etherum, etc. But, blockchain is not limited to cryptocurrency. It can be used on a wide range of areas where third party trust is involved.
