Are you familiar with Kusama’s Proof of Ink protocol, Kappa Sigmu Mu? It was started by Gavin Wood, the co-founder of Ethereum and founder of Polkadot. I got a tattoo of the Kusama ID like 3 years ago as part of that group. They had very clear rules on the tattoo and how to validate it periodically. I’d recommend looking into it. (The Human Blockchain: Join the Kappa Sigma Mu Society on Kusama Network - HackMD).
I’m not sure how realistic this is. Is there a budget for this proposal by the way? I didn’t see one.
Have you taken a look at the Guiness World Record gin and tonic AIP? (AIP-495: Organization of the Guinness World Record Attempt for the Largest Gin & Tonic During NFT Paris 2025)
