Ether (also known by its currency code ETH) is the native digital asset of the Ethereum blockchain platform.
Ether is an asset that operates as:
– a monetary vehicle for the transfer of value
– the unit of accountancy for the Ethereum network

Just as in the case with Bitcoin where 1 Bitcoin consists of 100,000,000 sub-units called satoshis; 1 Ether consist of 1,000,000,000,000,000,000 sub-units called wei.
