NFT User Story and Technical Requirements Outline

[deerwolf]

I am working in Rounds over many sessions and have put a lot of work into my music. I am happy with it, it is finished and it is ready to be shared with the world.

Before I do this however, I am going to “mint” my Rounds as an NFT. This way I can be sure that I can sign and be credited as the creator of my work, as the owner of my work and can assure that my music made in Rounds will live on in ways that make it accessible to people in a variety of different formats forever.

To do this I first navigate to the “Mint NFT” option through one of the three places of the UI:
Under the “Share” icon
From the Project drop down on the drop panel
From the “…” list on the Project list.

When I click “Mint NFT”, the app opens my Ethereum Wallet in a new tab / or launches app on Mobile. Here I can see the details of the NFT and am able to sign to confirm the minting via an “Are you sure you area ready to mint?” dialog.. Once the NFT is signed in my wallet, I am brought back to Rounds. At this point all my Rounds information (JSON from Firebase, MIDI export of the musical score, SoundFont2 export of the sampler instruments used, Raw Audio Files, and Project Image which is a snapshot of the rounds visualization for the project) are available for download. These assets are also uploaded to IPFS for future decentralized storage and their IPFS URLs are captured for display in Rounds.

Now that I have minted my Rounds, I can use the embed code provided in the “Share” menu to copy-paste-embed a read-only player version of my minted Rounds music. There is also a new QR code in the Share menu that links to the Rounds.studio NFT gallery. I can also see here the creator information (my ethereum address) as well as the owner information (also my ethereum address as I have not sold or transferred ownership of my work) along with the URL to all my Rounds assets on IPFS.
