This is an interesting idea but this is the wrong board for it. In all honesty, this thread should probably be moved to "Off-Topic" since it doesn't actually have anything to do with bitcoin, cryptocurrency or the blockchain. You should consider it because there's nothing from preventing anyone else from doing the same thing. If they do, is the "digital real estate" you're selling actually "scarce" anymore?
When you say, "the owner controls the visual block and link for that specific minute on the global grid", I'm not exactly sure what you mean, but this has to be a big enough incentive to keep it valuable. Anyway, putting it on a blockchain could therefore verify that people are getting the original one (yours). Good luck.
Thanks for the constructive feedback. You bring up the exact dilemma of Web2 vs Web3 scarcity, which is exactly why I wanted to discuss it here.
Fair point on the board placement—if the mods feel it fits better in Off-Topic, I completely understand and they are welcome to move it.
To clarify the "visual block" part: Think of it like the Million Dollar Homepage, but based on time instead of pure pixels. The site features a live grid displaying all 1,440 minutes. If you own the "12:00" slot, your custom image and hyperlink are permanently displayed in that specific block for all visitors to see. The incentive is global visibility and the ability to resell that prime slot later as traffic grows.
Regarding your point about clones: You hit the nail on the head. Anyone can copy the PHP and make a duplicate grid tomorrow. But just like anyone can fork a popular NFT collection or clone a social network, the actual value isn't in the code—it's in the network effect, the brand, and being the "first mover". The grid that captures the attention and community consensus is the only one that holds real estate value.
However, your suggestion about using a blockchain to mathematically prove people are buying into the *original* grid is spot on. If the secondary market continues to grow, bridging this to Web3 to verify authenticity might be the inevitable next step to protect buyers from clones.
I'll shoot you a PM with the link so you can visually see how the grid operates. It makes much more sense when you see it live!
