IPFS stands for InterPlanetary File System and is a peer-to-peer hypermedia protocol designed to make the web faster, safer, and more open. It allows anyone to upload a file, and that file is hashed so that if it changes, so does its hash. This is ideal for storing images since it means that every time the image is updated, the on-chain hash/tokenURI also has to change, meaning that we can have a record of the history of the metadata. It’s also really easy to add an image onto IPFS and doesn’t require running a server!

IPFS에 저장하면 된다
서버 구축할 필요 X
(IPFS node가 다운될 경우를 대비해서
Pinata 이용 가능)
