What does Finney, Szabo mean?
These are names for smaller denominations of Ether, with a Finney = 1/1,000,000,000,000 ETH and a Szabo = 1/1,000,000,000,000,000 ETH. These denomination names came from real life people, with the Finney named after Hal Finney, the first Bitcoin user after Satoshi Nakamoto, and the Szabo being named after Nick Szabo, who came up with the idea of Bit Gold and smart contracts.
