Posted this question in the Zano Telegram group named Stakin:
The Dev Fund received in this Transaction ID: https://explorer.zano.org/transaction/a247e6abf22415e0dd1ba44deb034c5f4bc37700a14d32aec21de861c7c789f8 a POS reward of 0.999430891264 ZANO instead of 1 ZANO. I am just curious to learn more why was it not 1, but less? What is the (technical) explanation for this?
Answer:
It’s a block size penalty, these two blocks happen to be very large
