I was wracking my brain on a way to honor Hal, and this is the idea I came up with. I shared on Reddit, Twitter, and other places, but I thought I would share here too. I propose we rename 0.0000001 BTC as the Finney. Just as we honor Satoshi for 0.00000001.

Or using scientific notification:

1e-7 BTC = 1 finney
1e-8 BTC = 1 satoshi

You can see other comments/discussion on Reddit:

Not sure how something like this becomes official, but I guess if enough people use it, then it becomes part of the Bitcoin language.
