Scoring System
[In-depth explanation of the scoring system in progress. For now, see Program Overview.]
MEV Commission Score
mev_commission_score = {
1.0 if max(mev_commission[t1, t2]) ≤ mev_commission_bps_threshold
0.0 otherwise
}
where:
t1 = current_epoch - mev_commission_range
t2 = current_epoch
Running Jito Score
running_jito_score = {
1.0 if any MEV commission exists in t1 to t2
0.0 otherwise
}
where:
t1 = current_epoch - mev_commission_range
t2 = current_epoch
Delinquency Score
delinquency_score = {
1.0 if (vote_credits[t] / total_blocks[t]) > scoring_delinquency_threshold_ratio
for all t1 ≤ t ≤ t2
0.0 otherwise
}
where:
t1 = current_epoch - epoch_credits_range
t2 = current_epoch - 1
Commission Score
commission_score = {
1.0 if max(commission[t1, t2]) ≤ commission_threshold
0.0 otherwise
}
where:
t1 = current_epoch - commission_range
t2 = current_epoch
Historical Commission Score
historical_commission_score = {
1.0 if max(historical_commission[t1, t2]) ≤ historical_commission_threshold
0.0 otherwise
}
where:
t1 = first_reliable_epoch = 520
t2 = current_epoch
Blacklisted Score
blacklisted_score = {
0.0 if blacklisted in current epoch
1.0 otherwise
}
Superminority Score
superminority_score = {
0.0 if in superminority in current epoch
1.0 otherwise
}
Vote Credits Ratio
vote_credits_ratio = sum(vote_credits[t] for t in t1 to t2) / sum(total_blocks[t] for t in t1 to t2)
where:
t1 = current_epoch - epoch_credits_range
t2 = current_epoch - 1
Note: total_blocks is the field in ClusterHistory that tracks how many blocks were created by the cluster in a given epoch. This represents the maximum number of vote credits that a validator can earn. Vote credits are synonymous with epoch credits.
Yield Score
yield_score = vote_credits_ratio × (1 - max(commission[t1, t2]))
where:
t1 = current_epoch - commission_range
t2 = current_epoch
Note: Yield score is a relative measure of the yield returned to stakers by the validator, not an exact measure of its APY.
Final Score
final_score = mev_commission_score × commission_score × historical_commission_score ×
blacklisted_score × superminority_score × delinquency_score ×
running_jito_score × yield_score
