Blocky saysNFTs are on-chain proofs of ownership for unique items — provable scarcity for digital things.
A non-fungible token records that a specific token id belongs to a specific address. That makes "owning" a digital item verifiable and transferable without a platform. The value isn't the image itself (anyone can copy pixels) but the on-chain provenance and ownership record. Use cases run from art to tickets to memberships.

Example code
<!doctype html><html><head><meta charset="utf-8"></head>
<body style="background:#06040d;color:#e6e0ff;font-family:monospace;padding:20px"><pre>NFT proves: 0xabc owns tokenId 7 (provenance)
NFT does NOT prevent: copying the image
NFT ≠ copyright by default</pre></body></html>
