@pete That's really cool!
Oh I just realized you can proof the value of your block by just showing the coinbase tx.
I wonder if you have a low-hashrate miner if you could build an invalid block with a high-value coinbase output to get larger shares as long as you never actually mine your block.
But I suppose the same holds for anyone mining an invalid block that gets paid.
However like this, mining invalid blocks might give you a higher payout over the long run as you're uncensorable anyway.
