The blockchain is an undeniably ingenious invention
– the brainchild of a person or group of people
known by the pseudonym, Satoshi Nakamoto. But
since then, it has evolved into something greater,
and the main question every single person is asking
is: What is Blockchain?

Dark Web
The Dark Web is a term that refers specifically to a
collection of websites that exist on an encrypted
network and cannot be found by using traditional
search engines or visited by using traditional

Web hide their identity using the Tor encryption
tool.

Silk Road was an online black market and
the first modern darknet market, best
known as a platform for selling illegal

Bitcoin Mining, Explained
Bitcoin mining is the process of adding
transaction records to Bitcoin's public ledger of
past transactions or blockchain. This ledger of
past transactions is called the block chain as it is
a chain of blocks. The block chain serves to
confirm transactions to the rest of the network as
having taken place.
