And on my desktop setups payment protocol URLs don't work = for various reasons, and I'd forgotten I'd manually disabled them ages ago. Just checked and Bitfinex, BTCC, and Shapeshift all don't seem to use the payment protocol. Other than BitPay and Coinbase, do you have an example of a service support= ing the payment protocol? > ~10 Mio BitPay users > 8 Mio Bitcoin Wallet users > Plus Bitcoin Core, Electrum, etc (sorry no numbers) >=20 > Probably the only usecase for naked addresses is paper wallets, right? > I'm not sure if paper wallets can expire. User-to-user payments pretty much always use naked addresses. --=20 https://petertodd.org 'peter'[:-1]@petertodd.org --azLHFNyN32YCQGCU Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- iQEcBAEBCAAGBQJZzk//AAoJECSBQD2l8JH7rmgH/j18CiwAAswJNTHgz7mr6E/G 5e+uaRnvAqnfNVUoLfs3vll1lOMkh3FXfuVwYJLffnNYToHdJpl+oZTRVDhF9C0T P1vUxEe1XHjwETgwFi3M1ltjXP9EWilAi+hzMKeLELOg7ZxW3mNGlMlqkPSdJHag fCJtMrt2M8v3++BpCY3piDShQf+wqM6vPxZbeFGrzSYK2EQ8JHVExVSxikcBvtq/ 6hDhKqhE3YOPpPGgnaswNp2ki6mZuNvBaJ7M4cGOA4MDH7kT8QNaKAnISbJLAlyE KPefAJ3GuDm9CqYN7B3k9AtIovQZQuK/HaS87crUTyskL7fDwo157Rr8MxABH8Y= =p8IC -----END PGP SIGNATURE----- --azLHFNyN32YCQGCU--
