I want a new procedure or so added to a private copy of the satoshi client 0.8.1. 

When finished, there should exist a new RPC call not unlike
    getcoinbasepayouts <hash> [n=1]
where n is the number of blocks to accumulate totals over.  This shall work even if the block-hash is a chain-tip that is stale.  The default for n is 1.

The output from this RPC call shall give the list of all bitcoin addresses and their corresponding amounts that were paid in coinbase transactions by block-hash and the previous n-1 blocks.  It should not be stylistically jarring compared to the other RCP responses.

Please feel free to produce a quote on producing the diff files which produce working source when applied to
    git clone https://github.com/bryan-mills/bytecoin
This alt-coin client is virtually identical to the 0.8.1 bitcoin client.  You may or may not be able to develop your code from the core 0.8.1 bitcoin client on the bitcoin block-chain if you already have that on hand.

I am still undecided whether this alt-coin was an April fool's prank or not, I am aware that the last block was mined on or near last September 2016, and that there may not be any active nodes, other than my intermittent one.

The terms will be fixed bid, pay on acceptance.  I do not think there is a large amount of work for someone already up to speed.  This request is valid for delivery by April 1, 2017, but may be re-issued.
