Say, the total payout of mining a block is half of the fees from the block you mined, a quarter of the fees from the block your parent mined, an eighth of the block before that, etc. The fee payout of mining a block becomes the sum of block_n_fees * 1/n^2 for the last n blocks (bounded by the minimum respresentable value, "1 Nakamoto" or whatever it's called).
