one other thing I haven't been able to figure out... do we know what a "block" is?  Is one block equal to one plot?  Or do a series of your plots constitute one block?

I'm imagining that you have 629 blocks, right now doing nothing but sitting there waiting to be picked by the lotto, right?  So you win a block and now one (or more) of your plots are being utilized by the blockchain, is that an accurate understanding?
