Activity becomes density
Transaction count is normalized against the prior 512 selected blocks, then mapped to 8–128 visible elements.
Data is Beautiful
Cardano, seen from inside the block.
Every block carries a fingerprint: activity, value, time, and a hash that identifies it on-chain. We turn those signals into deterministic chainprints you can inspect all the way back to the ledger.

The signal in the noise
Three characters. Twelve bits. One strange lens.
This study follows historical Cardano block hashes beginning with
ada. A three-digit hexadecimal prefix represents 12
bits—an expected frequency of roughly one in 4,096 under uniform
hashing. The prefix finds the blocks; the data inside each block
makes every result different.

The block atlas
Twenty-five chainprints. One reproducible system.
Trace the river, filter a geometry, or let the atlas drift. Dot size follows transaction count; vertical position follows total block output on a logarithmic scale.

Decode the mapping
The picture is a data receipt.
Change the source block and the picture changes. Keep the source block, prior-epoch normalization snapshot, and mapping version fixed, and the same SVG returns byte for byte.
Value bends symmetry
Total block output contributes to the visual symmetry score and spatial intensity. It is not presented as economic volume.
The hash chooses a language
Hash-derived seed bytes select palette, layout, scale, accent, texture, and perceived motion without a random reroll.
Time tunes the geometry
Epoch and absolute slot influence deterministic placement and framing, tying the composition to its position in chain history.
A new kind of block explorer
Don’t just read the chain. Learn to see it.
Ledgers are usually presented as tables, hashes, and totals. Data is Beautiful asks a different question: can Cardano’s structure become a visual language that remains inspectable, reproducible, and unmistakably its own?

Built with the same bias: verify first.
Simba Pool is the public home for this experiment and our wider work around Cardano data, transparent infrastructure, and useful on-chain receipts.
