Blocks is a fully on-chain collection: one NFT for every Ethereum block, from genesis #0 to #29,999,999, all 30,000,000 of them. Each block's artwork is generated on-chain from that block's own data, so every piece is a unique fingerprint of a real moment on the chain. The whole collection is wrapped across the six faces of one cube; each face is a layer of ~5M blocks you can explore, mine, own, and paint.
Dual token (DN-404 / ERC-7631). Blocks is an ERC-20 (ticker BLOCKS) and an ERC-721 at the same time, linked 1:1, so 1 whole BLOCKS = 1 block NFT. It trades on a DEX like a token and sits in your wallet as an NFT.
On-chain art & data. Every NFT is a treemap mosaic seeded by the block's blockHash, carrying 9 real on-chain traits: height, timestamp, transactions, block reward, size, withdrawals, gas used, log events, and base fee. tokenId = block height (so tokenId 0 = genesis, July 30, 2015).
Mining. Sacrifice 0.00001 ETH + gas per block, up to 150 in one transaction. Blocks the chain hasn't produced yet (the darker future Blocks) can't be mined until the chain reaches them.
⚠ How the 404 moves your blocks. Your NFTs follow your whole balance (5 whole BLOCKS = 5 block NFTs). Trading, sending a fraction, or adding BLOCKS to a liquidity pool releases your specific block NFTs back into the open pool, where a rare or beloved Block can be bought out by someone else and lost to you forever. Keep any Blocks you want to keep in a wallet you won't trade from or add to a liquidity pool, and hold whole-number balances so your blocks stay yours.
Block Theory turns Ethereum into a giant virtual map: every block is land, every transaction a plot, every event log a pin — parcels you can own, trade, and (once builders deploy on top of this contract) build real applications on. Every Ethereum block from Genesis Block #0 to #29,999,999 is archived on-chain in this collection, Blocks — 30,000,000 of them, until the last Block is claimed. Blockspace should be cheap, and the people who use the chain decide what it costs. The Block you mine is land you own. Add it to liquidity pools, list it on NFT marketplaces, build on top of your land, or use it as a billboard on the main BLOCK. Each mine batches up to 150 Blocks into a single transaction of roughly 22 to 26 million gas — a meaningful slice of an Ethereum block, sized to sit at or under the post-EIP-1559 gas target (~30M of the ~60M cap), so every mine is real demand at the gas price you set and leaves room for the rest of the block. Mine at the lowest gas you'll accept and never bid it up: EIP-1559 ticks the base fee down by up to 12.5% per block that runs under target, so a backlog of floor-priced mints compounds the fee back toward zero. Walk the base fee home to genesis (block #0, July 30, 2015). 30,000,000 disciplined claims is a multi-year covenant, not a sprint.
