What is a blockchain?
A
blockchain, originally block chain, is a growing list of records,
called blocks, which are linked using cryptography. Each block contains a
cryptographic hash of the previous block, a timestamp, and transaction
data.
By design, a blockchain is resistant to modification of the data. (Source: Wikipedia)
