@detlev - sorry for tagging you as André has no account - Costs for such a world record are the issue - however if we compare to our Rally Car costs why not worth a try - of course you need invest for a big success - and it needs to be focused on a REAL use case - hence I like the idea more and more now. Being part of a record awesome - the smart solution via Poland is cool - to be part of an NFT seems to attract certain communities that wanna be part of something or able to touch something and then own an NFT - true ownership of physical and digital assets combined is good - we need to make sure the value of the digital thing has a chance to increase in value - but did not see it yet or I missed a thing.
Second one with Canvas to Blockchain by scan QR code of a graphic - you own picture behind the picture - nice for people interested in such things - André mentioned Hologram and then QR code would be an additional security feature - is that real? Can hologram not be copied at all? Adding @reiseamateur who might know more here than me.
