Satoshi to Nicholas Bohm: the +50.10 was a transaction fee (May 24, 2009)

That’s the transaction fee feature. If you generate a block containing a transaction that includes a transaction fee, you earn the transaction fee in addition to the 50.00. Someone must have included a 0.10 fee with one of their transactions. The setting to do that is under options. Including a fee is completely optional, more of a donation to nodes for helping out.

Bitcoin continues to run smoothly, but I noticed an unusual event:

731 blocks      11/05/2009 15:58    Generated         +50.10

All prior and subsequent generated packers have been of exactly 50.

Just in case this is of interest!

Regards,

Nicholas
