A living portrait of Bitcoin at this exact moment. The glowing ring is the next block — a block that does not yet exist, which miners around the world are competing to produce right now. Around it, the live mempool: transactions competing for limited block space, the higher-paying gathered closer in. The dashed boundary marks the population currently projected into the next block — inside it, every light is a specific projected transaction; the wider field beyond is drawn statistically from the live mempool at the scale shown (white-cored points are individually observed). The network writes the events; the artwork supplies the motion. Nobody knows when the next block will come. When it does, the projected front of the queue collapses into it, and the newborn block becomes a deterministic constellation — generated from its immutable Bitcoin data, identical for everyone who ever looks it up. Tap any dot inside the dashed boundary to inspect it.
