Unit 3 · Level 4 · NFTs beyond jpegs
Unit review: NFTs
You now know what an NFT actually is (a provenance record, not a jpeg), what the mania taught (attention prices round-trip), how the market tricks you (floors, sweeps, wash trades), and where the tech might genuinely earn its keep. Quick lap to lock it in.
Free to play. No ads, no token, no account needed to start.
What you get asked
Your friend says 'I bought the image'. What did they actually buy?
The chain stores the receipt; the image usually lives elsewhere, and copyright usually stays with the creator.
The cheapest listed NFT in a collection sets the ___ price.
And that floor is only as real as the next actual buyer; thin markets make quoted prices optimistic.
Match the phenomenon to the honest lesson
Four headlines, one thread: check what's real before believing what's loud.
A collection's floor is 0.8 ETH and ETH trades at €2,500. What's the floor in euros?
0.8 × €2,500 = €2,000, if and only if a real buyer shows up at the floor.
Which NFT use case has the strongest 'why blockchain?' answer?
When strangers need to verify ownership without trusting a middleman, the receipt earns its blockchain. Everything else has to beat a database on merit. 🐜
