How it works #

It is a static site, built from block.space's public API (https://block.space/api/largest-inscriptions), with the thumbnails copied into the site, so the pages load nothing from another origin. The Space Blocks facts are fixed and checked against block.space on each build. The site is rebuilt daily at 00:40 UTC. Its whole-blocks page lists the whole-block works, largest first.
