metaplex VS IKB

What blockchain would offer the best pre-built libraries and out of the box support to get a marketplace up and running quickly? Probably solana is my bet, based on libraries like this --> https://github.com/metaplex-foundation/metaplex

The use of the candy machine smart contract is very low cost though; it just takes some on-chain rent for data storage until the end of the mint, and you'll probably want to pay arweave storage fees in SOL, so that the NFTs themselves have adequate longevity. But when it comes down to the minting website, it's open source software that's free to use. Look for the candy-machine-ui in Metaplex's offering. If you have JavaScript experience, it's pretty straightforward to integrate into your project website.

Did you lookin git? https://github.com/metaplex-foundation/metaplex

To upload the pngs to Solana we are going to use Metaplex, the protocol that is defining the NFT standard for the network. Go to Github and clone https://github.com/metaplex-foundation/metaplex

You can deploy smart contracts if you want, but it is highly recommended to use Metaplex (Docs here) since they already deployed the infrastructure and is currently the popular NFT standard.

> This is not only not a very convincing argument, it's a little bit of an insulting one.

My apologies if I came across as insulting, but I do feel a sense of frustration with some of the arguments provided in discussions like these, and I think we can agree that some of the language critiquing NFTs here does not scream "open minded".

First, let me correct a misconception that may give you a slightly different perspective. You write "since there are multiple blockchains that handle NFTs, an NFT is just unique on that blockchain". It is worse than that! There is nothing that enforces uniqueness of an NFT within a single blockchain; not in a way that would make such a duplicate any different than a duplicate on a different chain. You couldn't prevent such duplicates, even if you wanted to. First, artists may on purpose create multiple copies; second, the only way such unique could be detected would be hashes, which can easily be fooled. Third, a scammer minting an NFT of an image belonging to an artist, would then block that artist from being able to mint the NFT themselves. It sounds bad, but it really doesn't matter for the concept to work. People scamming by pretending they are selling art pieces they did not create is a problem, but it is not a problem NFTs set out to solve (and indeed cannot).

The NFT does not confer any legal rights, correct. But what legal authorities would you want it to confer to the owner? There are a couple that are really useful: The right to download a copy of the art piece from a website. Yes. The right to use the art piece as a profile picture on Twitter. Sure! And artists do often provide license agreements along those lines. (If they don't provide any license information, I believe an owner could try to argue that there is an implied license, and may or may not succeed in that claim.) Some artists put their work even into the public domain.

I would agree that owning an NFT which you do not have the permission to copy to your hard-drive, or which you cannot see on OpenSea because the artist refuses to allow OpenSea to show that image, seems quite degraded. It will probably be not very popular. And yet, some people just might pay for it anyway, because the ownership of the token on a blockchain is what matters in the end. If a popular artist such as beeple were to publish an NFT, explicitly denying that the owner has any rights to even make a copy of the image, there is no doubt someone would buy it. Call it conceptual art. There is no legal system required, because like you say correctly, the NFT itself does not confer any legal rights. The blockchain is the definitive record of ownership, because legal modes of ownership are basically orthogonal.

Consider the example of Mitchell F. Chan's Digital Immaterial Zones (I recommend the blue paper: https://github.com/mitchellfchan/IKB/blob/master/Digital-Zon...), which explicitly is a token without any visual media attached; there is nothing that exists outside of the blockchain that you even could own. It is the pure distillation of this idea.

There is a difference between an artist saying "you have the right to download my file" and the artist saying "I consider you the owner of this immaterial piece that I created, I will only acknowledge 10 owners maximum, and also all of you have the right to download the file".

The latter kind of agreement can certainly be modeled with a conventional contract, and indeed that has been done in the art world, but it is just so much easier on a blockchain to track those 10 owners, verify that the person selling to you is an authentic owner and that they sell their claim only once, and so on.
