The metadata document at that URI describes the token and points to its image. If either pointer can be changed without limits, the thing a collector sees can change even though the token itself never moved.</p> <p>That is a trust problem.</p> <p>In this post, I will use <a href="https://ipfs.tech/">IPFS</a> and <a href="https://www.pinata.cloud/">Pinata</a> to give the image and metadata layers content-addressed identities. I will also use my <a href="https://github.com/Coderrob/pinata-ipfs-scripts-for-nft-projects">Pinata IPFS scripts for NFT projects</a> to pin images independently and pin the finished metadata as a directory.</p>
