It's not a proposal, It's already in the Bitcoin Core client.
Just to make sure I fired up my Bitcoin QT client and, sure enough, it displays bitcoins to 8 decimal places. So the Bitcoin QT client is displaying satoshis as described above (100,000,000 satoshis = 1 bitcoin). I do not have the very latest version of the Bitcoin QT client. Did they switch to displaying only six decimal places? Can someone with the latest client look into this and let me know if they changed something (especially related to the definition of the "satoshi").
Why use "bits" when you can use "sats"?
You could use either. A bit is just a shorthand for 100 "sats" (assuming you are using "sats" as a shorthand for satoshis). Use BTC, bits, sats, or satoshis - whatever your heart desires.
BTW I have never seen anyone anywhere seriously propose that we change the definition of a satoshi from 100,000,000 satoshis/BTC to 1,000,000 satoshis/BTC.
That would cause some real confusion!If anyone sees a proposal to change the definition of the satoshi please let me know so I can give them a piece of my mind. The satoshi, as 1/100,000,000 th of a BTC, is pretty much set in stone at this point as far as I and everyone I know is concerned. Please, let's not mess with that.
