This application is built on the Flow blockchain using fcl-js to interact with the blockchain. It is a fully frontend application. It allows users to prove proof of ownership of their assert on IPFS (InterPlanetary File System). Ownership can be publicly verified by comparing the signature retrieved from the blockchain to the accompanying account address.
