Rarity on PopRank

Our Rarity Calculation

rating(num_nfts_with_trait, collection_size) = collection_size / num_nfts_with_trait
Shoutout @_etash for allowing us to feature his 4T ape
  • Reduce the rating difference between similarly rare traits
  • Have the meta Trait Count be more impactful
  1. Reduce the rating difference between similarly rare traits
def rating(trait_type, num_nfts_with_trait, collection_size, average_trait_count):
return collection_size / math.sqrt(num_nfts_with_trait - 0.8) * (average_trait_count if trait_type == "Trait Count" else 1)

Going Forward

Closing Thoughts

  1. transparently provide a range of rarity calculations that collectors can choose between
  2. give collection owners the ability to indicate their preferred rarity calculation
