Solidity is one of the languages that is used to author smart contracts. Smart contracts will be dealt with in detail in the following chapters.

Earlier, Solidity was part of the Geth installation; however, it has moved out of Geth and should be deployed using its own installation.
The Solidity compiler also known as solc can be installed using npm:
npm install -g solc
The preceding command line generates the following output:
