Hey everyone,
does anyone know where the rarity classification for a Moment is stored on NBA Top Shot? (common, rare and legendary). I didn’t find it in the metadata - maybe it’s stored outside the chain?
Tnx
The rarity classification is not stored on chain, though it is based on on-chain data. Moments on-chain have a certain number minted for each edition, and editions that have less moments in them are generally considered more rare. Does that make sense?
Tnx @flowjosh thank you for your prompt answer. That is helpful. And how are Editions stored on-chain? All that I can see in the contract: Series, Sets, Moments & NFTs. And what is the logic behind Packs?
an edition is a combination of a set and a play. The number of moments in an edition is tracked by this field: https://github.com/dapperlabs/nba-smart-contracts/blob/master/contracts/TopShot.cdc#L246-L250
They don’t call them editions on chain, but they do off-chain.
Packs are also an off-chain construct for now, but that will change in the future
Tnx @flowjosh - awesome
@flowjosh, in your post from September 2021, you wrote “Packs are also an off-chain construct for now, but that will change in the future”
has there been a change to include pack information on–chain? thanks.
No, there has not be a change to include pack on chain yet. The team is working on a mechanism for it, but it is still in development. On-chain packs are difficult to get right.
