The purposes behind NFTs and IPNFTs are somewhat different although they can both be combined with an artistic element to boost their value.
I understand the purpose of IPNFTs is to allow fractionalised ownership rights to IP (such as RCT data and patent rights generated by a particular project), and provide the owner with rights to receive outcome or royalty payments proportional to their ownership.
I had envisioned using artwork NFTs as a crowdfunding mechanism to raise a “public good” / longevity generic drug repurposing fund under a pay for success contract proposed in VDP-17: VDP-17: CrowdFundedCures.org Partnership Proposal - Generic Drug Repurposing Social Impact Bond. The amount paid for the NFT would represent what someone would pay for an off-patent longevity intervention that has been shown to work in Phase 2 or 3 RCTs. Ideally, there would be a royalty paid into the generic drug repurposing fund every time the NFT is sold (e.g. 10-20%).
Both IPNFTs and off-patent NFTs could be combined with artwork to boost their value, but this way, their value is also tied an investment in longevity R&D. It would be great to try and see if this would work with our proposed PFS model outlined in VDP-17 and also perhaps use the funds raised to support a Gitcoin round and leverage the quadratic funding to boost the amounts available in the longevity public good / generic drug repurposing fund. Of course, for this specific project, it might be a bit complicated and easier just to keep them as plain artwork NFTs / collectables.
