a smesher creates votes in the following steps: - select a Ballot in the past as a base Ballot - calculate the opinion difference on history between the smesher and the base Ballot - encode the opinion difference in 3 list:

  • ForDiff contains blocks we support while the base ballot did not support (i.e. voted against) for blocks we support in layers later than the base ballot, we also add them to this list
  • AgainstDiff contains blocks we vote against while the base ballot explicitly supported
  • NeutralDiff contains layers we vote neutral while the base ballot explicitly supported or voted against

example: layer | unified content block ----------------------------------------------------------------------------------------------- 

N   | UCB_A (genesis)

----------------------------------------------------------------------------------------------- 

N+1  | UCB_B base:UCB_A, for:[UCB_A], against:[], neutral:[]

----------------------------------------------------------------------------------------------- 

N+2  | UCB_C base:UCB_B, for:[UCB_B], against:[], neutral:[]

----------------------------------------------------------------------------------------------- 

(hare hasn't terminated for N+2)
N+3  | UCB_D base:UCB_B, for:[UCB_B], against:[], neutral:[N+2]

----------------------------------------------------------------------------------------------- 

(hare succeeded for N+2 but failed for N+3)
N+4  | UCB_E base:UCB_C, for:[UCB_C], against:[], neutral:[]

----------------------------------------------------------------------------------------------- NOTE on neutral votes: a base block is by default neutral on all blocks and layers that come after it, so there's no need to explicitly add neutral votes for more recent layers.

TODO: maybe collapse Support and Against into a single list.
