A deep dive into BlockChain Technology

A Definition of the Term „BlockChain“
“A blockchain […] is a distributed database that maintains a
continuously-growing list of ordered records called blocks. Each block
contains a timestamp and a link to a previous block. By design
blockchains are inherently resistant to modification of the data: once
recorded, the data in a block cannot be altered retroactively.”
https://en.wikipedia.org/wiki/Blockchain_(database)
