The ERC1155 smart contract utilizes an immutable URI that points to a link that stores the JSON file. Decentralisation is achieved through storage of data files in IPFS systems, which delivers content with a peer-to-peer distributed method of storage. Consequently, files stored on a public domain are subject to garbage collection, which deletes the file after a period of inactivity. IPFS pinning services allow content to be marked available even with a period of inactivity, by redistributing the file.
