Glyphs allow Bitcoin transactions to etch, mint, and transfer Bitcoin-native digital commodities. They are very similar to the Runes protocol, but rely soley on OP_RETURNs, and do not support inscriptions. Glyphs are designed to be compatible with nostr npubs and bitcoin taproot.
Whereas every glyph is unique, every unit of a glyph is the same. They are interchangeable tokens, fit for a variety of purposes.
Glyph protocol messages, called glyphstones, are stored in Bitcoin transaction outputs.
