I'm collecting here a few essays on the net about tokenization in the art world. This list is likely biased and by no means exhaustive.

There are a growing number of articles providing various thoughts and criticisms, but I haven't found too many that dive into the technical underpinnings of NFTs for a beginner-ish audience (i.e. somebody who may be fairly tech savvy but not an expert on code/blockchain/etc). I think this is fairly important, as those using NFTs and crypto typically own their own private keys and thus need to own their own security (i.e. a bank is not managing their assets for them), and so the more they understand the technology the better prepared they will be to deal with phishing & exploits, and the less likely they will be to make mistakes.

Please let me know if you find further resources.
