Bitcoin merchant adoption starting around 2012

How do discover merchants that accept bitcoin?

• OpenStreetMaps is open source and adaptable through tags
• Coinmap began displaying this data through an easy to navigate web interface
• CoinATMRadar began building its own proprietary database
• Point of Sale services may have their own proprietary maps, e.g. IBEXMercado

The case for OpenStreetMaps

• Open
• Wiki-style editing process (or use a web form)
• Adaptable
• Easy to build on top of or integrate, e.g. local communities or payment processors
• Data is often mirrored into corporate competitors

Tags commonly used:

currency:XBT=yes
payment:onchain=no
payment:lightning=yes
payment:lightning_contactless=yes
