To my knowledge there aren't any SPV implementations that do address caching; they all use the peer servers in a centralized fashion every time they connect. If those peer servers are setup to only return nodes on one side of the fork or the other, that's all they'll connect too and they'll never see another chain. --=20 'peter'[:-1]@petertodd.org 00000000000000000402fe6fb9ad613c93e12bddfc6ec02a2bd92f002050594d --l+goss899txtYvYf Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- iQGrBAEBCACVBQJV1Q/oXhSAAAAAABUAQGJsb2NraGFzaEBiaXRjb2luLm9yZzAw MDAwMDAwMDAwMDAwMDAwNDAyZmU2ZmI5YWQ2MTNjOTNlMTJiZGRmYzZlYzAyYTJi ZDkyZjAwMjA1MDU5NGQvFIAAAAAAFQARcGthLWFkZHJlc3NAZ251cGcub3JncGV0 ZUBwZXRlcnRvZC5vcmcACgkQwIXyHOf0udyPqgf+NUpK0nadAMo9aYiYPfT0RGHR bitQdh1Gr1bmkbg2Hx0SCa4GI5BzwwHP2zeNnnrePp+ixpXRIIk6E0oMBs49TXo/ 1hBTs/wJ+vD7kOmqjQVYV7W0X2GDX4s6kF+05wEx7katv7BTtHDIjaCcGMgvTvfq geswmJ/3j4szxxHLih6Z1QJf+iB6OOPPdP8m7BKyOC9K944+i5Z5LM196+eofvEL JXsvgALjiDu0nKifABM7UZaYEv5MlOo41GJ6x/dSWK0DCOJ3e6SfbQvl3Jghk8Eg NAFcf9KlnX/NTyWVubPGYJUtQvVma6PIHwftgnzN1qENojJ8e2+Xb132NY3oQQ== =7cJp -----END PGP SIGNATURE----- --l+goss899txtYvYf--
