type VerifiedActivationTx struct {
	*ActivationTx
	// contains filtered or unexported fields
}

func (*VerifiedActivationTx) BaseTickHeight added in v1.0.0 

func (vatx *VerifiedActivationTx) BaseTickHeight() uint64

BaseTickHeight is a tick height of the positional atx.

func (*VerifiedActivationTx) GetWeight added in v1.0.0 

func (vatx *VerifiedActivationTx) GetWeight() uint64

GetWeight of the ATX. The total weight of the epoch is expected to fit in a uint64 and is sum(atx.NumUnits * atx.TickCount for each ATX in a given epoch). Space Units sizes are chosen such that NumUnits for all ATXs in an epoch is expected to be < 10^6. PoETs should produce ~10k ticks at genesis, but are expected due to technological advances to produce more over time. A uint64 should be large enough to hold the total weight of an epoch, for at least the first few years.

TickHeight returns a sum of base tick height and tick count.

type Vote added in v1.0.0 

type Vote = BlockHeader

Vote additionally carries layer id and height in order for the tortoise to count votes without downloading block body.

type Votes added in v1.0.0 

type Votes struct {
	// Base ballot.
	Base BallotID
	// Support block id at a particular layer and height.
	Support []Vote `scale:"max=10000"` // sliding vote window size is 10k layers, vote for one block per layer
	// Against previously supported block.
	Against []Vote `scale:"max=10000"` // sliding vote window size is 10k layers, vote for one block per layer
	// Abstain on layers until they are terminated.
	Abstain []LayerID `scale:"max=10000"` // sliding vote window size is 10k layers, vote to abstain on any layer
}

Votes is for encoding local votes to send over the wire.

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.
