HashSpiral is NFTs in form of the ERC721 compatible Smart Contract on the Etherum blockchain.

Each Item has a unique randomized seed which is used by a deterministic, procedural algorithm. This means that every NFT is strictly linked with its image and metadata – the algorithm always generates the same HashSpiral from a single seed.

After all items are minted, binaries of the algorithm will be published, so everyone will be able to regenerate any NFT from its seed.

MD5 checksums of binaries are already printed on the Smart Contract, which prevents any modifications of the algorithm.

Full ownership and unlimited commercial usage rights are given to the owners of HashSpiral.

Metadata of NFT also contains raw data about Etherworld’s content, so it can be used by other developers.
