FAQ

Where does BTC Map take its data from?

The data is provided by OpenStreetMap:

https://www.openstreetmap.org

Can I add or edit places?

Absolutely, you are very welcome to do that. This is a good place to start:

Tagging Instructions

BTC Map shows a place which doesn't exist, how can I delete it?

You can delete such places from OpenStreetMap and BTC Map will pick up all your changes within 10 minutes.

I've found a place on BTC Map but it doesn't accept bitcoins

OpenStreetMap might have outdated information about some places, you can delete the currency:XBT tag or set it to no in order to remove this place from BTC Map.

Verifying signatures

Release APKs are signed by a long-lived release key owned by the BTC Map team. You can verify the signature by checking the certificate's SHA-256 fingerprint:

a63de0923b0c27e3de6ef4e90f3a0d81cca917f9689d2638f1b31949657f1435

With apksigner

The Android SDK build-tools include apksigner:

apksigner verify --print-certs path/to/app.apk

The SHA-256 digest line for Signer #1 certificate should match the fingerprint above. The certificate subject is O=Team BTC Map.

With keytool

If you'd rather inspect the certificate from a downloaded APK directly, unzip it and pass the META-INF signature block to keytool (the exact filename under META-INF/ varies between builds):

unzip -p app.apk META-INF/*.RSA | keytool -printcert | grep SHA256
