What is a collection on block.space?

A set of NFTs with a membership source (chain, index or asserted), ranked by blockspace.

A collection on block.space is a set of NFTs with a membership source, its provenance: chain (written on Bitcoin, such as parent inscriptions), index (a protocol's own index) or asserted (a published list, such as the Degent Club list). block.space/collections ranks them by blockspace, by Book A by default. Fungible tokens are left out.
