Every Bitcoin block is a day that happened once. Type a block number — or a date — and see it drawn from its own transactions, as a true bitmap district. If it's still free, seal it and name it forever, in a single move.

◱ Reading the districts
Watch Bitcoin fill up
Each district is drawn from its block’s real transactions, and sized by how full that block was. For the first two years almost no one was sending coins — most blocks carried nothing but the miner’s reward, so those districts are mostly open ground. Then the chain fills, block by block, year by year.

How sealing works. Bitcoin blocks are public history — they belong to no one. A district is the museum's on-chain label for a block: sealing one inscribes your claim on the DOM wallet and, if you name it, burns 0.05 ICP into the museum's endowment. One block, one owner, one name — forever. •
What it isn't. Sealing a block is a cultural act, not ownership of the Bitcoin block itself, and names are references — not affiliation with any company, product or person. Claiming happens in the DOM wallet.
