Provenance
The provenance record of each Space Ghoulie spawned. Each image is firstly hashed using the SHA-256 algorithm. This hash is stored individually on each Space Ghoulie's metadata on the Solana blockchain. A combined string is obtained by concatenating the SHA-256 of each Space Ghoulie image in the specific order as listed(ascending order starting from 0). The final proof is obtained by SHA-256 hashing this combined string. The final provenance record for each Space Ghoulie is stored on chain as well. This means there are two hashes stored on each Ghoulie's metadata. The final provenance hash and the individual Space Ghoulie hash for the image.
Credit to the Bored Ape Yacht Club for this hashing idea. Though most Solana NFT collections don't provide this type of provenance we've found that additional reassurance is important. Not only is it additional reassurance, but it also guarantees you get the original Ghoulie image and assets handed to you come post-mint. You could simply hash the asset you receive and see that it matches the same hash stored on chain. We realize it isn't completely necessary for the Candy Machine smart contract or on Solana, but we'll have a blog post talking more about this shortly. We will have all the information and more found on that post and on our website.
