The Ether denominations are called Finney, Szabo, and Wei. What/who are these named after?
When Satoshi announced the first release of the software, I grabbed it right away. I think I was the first person besides Satoshi to run bitcoin. I mined block 70-something, and I was the recipient of the first bitcoin transaction, when Satoshi sent ten coins to me as a test. I carried on an email conversation with Satoshi over the next few days, mostly me reporting bugs and him fixing them.
Please note that Solidity 0.7.0 removed the `finney` and `szabo` denominations. The reason is because "They are rarely used and do not make the actual amount readily visible. Instead, explicit values like `1e20` or the very common `gwei` can be used."
