With that patch people are still free to choose to provide bloom filtering services by setting -peerbloomfilters=3D1 > I believe there's a network security obtained by having a large quantity = of > people following the Bitcoin headers based on longest weighted chain.

There really isn't due to sybil attacks; we already have good reason to bel= ieve that the Bitcoin network is subject to them by deanonymization/chainanalysis services. Indeed there's a good argument that creating services that are vulnerable to sybil attacks encourages them by making them succesful at something. That creates its own risks, for instance the risk that the sybil attacker will themselves screw up and cause a bunch of nodes to go offline at once. --=20 https://petertodd.org 'peter'[:-1]@petertodd.org --vomkg5jbtcqzt3cv Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEFcyURjhyM68BBPYTJIFAPaXwkfsFAl03b90ACgkQJIFAPaXw kfto/Qf/VF/0LSq8Uw15YzoR9wynw/2zJvrm5YCy71Ju06/QHXLA84wXk89uQDUv Kg2eAptgkQvQ56qDBNXHv2TBaAby14hm2euq+DpHPWwtSIvuHDMH0bE879vzaatN znB+2pjX0WWUkuclmDe4jaZ0qPgup1f5WkJlcQSpyfK4WqyIUF1VHoG1wRtB3PyX /kRpl5GydDTBZepcdy+eWG4i2IpVk3l7pdPtVlwQfnpkzZIQjuKEzLawVTdW4Uc1 FJPrLuJCZtITEe+lxn8dVzHLaO6J26vheDLfzwbSo6QlEERQLW4cG3Wm6jee6lS7 WeigJQkOiraGO26k9Yrc0dfemNLpgw== =S/sE -----END PGP SIGNATURE----- --vomkg5jbtcqzt3cv--
