This page is one file and nothing else. Your browser connects straight to mempool.space over its public API — there is no server behind this site, no accounts, no analytics, and nothing leaves your machine. When Parasite mines a block, the page takes over the screen and draws the block's real shape — every rectangle is an actual transaction, sized by weight, colored by fee rate. Download the file and open it locally and it works exactly the same. The pool itself lives at parasite.space.
