Why are empty blocks not all the same size?
On Monero Blocks I see a different size for blocks with zero transactions.

1157855 block size 210
1157856 block size 254

Usually, empty blocks can vary within a couple bytes, as monero amounts (present in the coinbase transaction even in "empty" blocks) are stored in a varying length encoding.

1157856, however, is a lot larger because it's got extra info in the extra field. It's probably been mined by MinerGate, who tends to add their own private information in blocks.

  • The amounts in empty blocks is related to the block reward I assume?

  • Amounts of what ? If amounts of monero, yes.

  • "Amounts of what ?" => Actually I didn't know. I was referring to the amounts in your answer. (by the way; thank you for the quick and useful answers)

  • Ah, yes, it is amounts of monero in that case. I will edit for clarity.
