List of publicly known Ethereum addresses (name tags) as seen on https://etherscan.io/
Before the creation of the Ethereum name service there were no official way to identify the ownership of an Ethereum address.
Etherscan provided a name tag to help Ethereum users differentiate important addresses from others and bring more confidence to a user when sending values to an identified address.
