A Bid-Based NFT Advertising Grid

This is an experiment in creating finite, competitive digital advertising space using NFTs. The system consists of a fixed grid of positions, where each position is represented by an NFT and ranked by bid value. Higher bids move ads upward in the grid, while displaced ads shift downward rather than being removed. There are no buyouts, no resets, and no infinite inventory — just continuous price discovery over scarce digital real estate.

NFTs are used here not as art objects but as transferable claims to ranked positions within a bounded system. Ownership, bidding history, and placement are verifiable, while most ordering logic remains off-chain to keep costs low. The goal isn’t click-through optimization but persistent visibility and transparent competition, closer to a public billboard than traditional digital advertising.
